MARINE COMPOSITIONS BEARING PREFERENTIALLY CONCENTRATED DOMAINS OF NON-TIN, ORGANO ANTI-FOULING AGENTS

Abstract: The present invention is addressed to a curable, marine anti-fouling composition of a thermoplastic or thermosetting binder, solvent, non-tin, organo anti-fouling agent, and optionally conventional additives, e.g. leaching agents, opacifying pigments, etc. The anti-fouling agents are found in preferentially concentrated domains (hereinafter, often referred to as ''PCD'') in the cured compositions. The PCDs can be termed non-homogeneous, phase-separated, or incompatible in the system. The art term used in describing the PCDs of anti-fouling agent is not limitative of the invention as the disclosure herein will demonstrate. Preferably, PCDs are created by forming an oligomeric adduct of the anti-fouling agent which adduct is formed into PCDs upon the curing of the composition. Additional techniques for forming PCDs of anti-fouling agent are revealed herein. The present invention also is addressed to new, low toxicity anti-fouling agents which comprise pesticide or herbicide compounds having a chi factor of between about 0.01 and 3, a Z value for vinyl or aromatic compounds of between about 0.01 and 0.08, and an LD50 value of greater than 200 mg/kg against rats or mice. Such pesticide or algicide compounds broadly can be selected from heterocyclic compounds, aromatic compounds substituted with heteroatom substituents, various amino compounds, carbocyclic vinyl ether ketones, certain phospho compounds, certain polychlorinated carbocyclic and acyclic compounds, certain chlorinated carbocyclic carboxylates, antimony tartrate, boric acid, and cupric oleate.

Description: MARINE COMPOSITIONS BEARING PREFERENTIALLY CONCENTRATED DOMAINS OF NON-TIN, ORGANO ANTI-FOULING AGENTS Background of the Invention The present invention relates to anti-fouling marine coatings and mor particularly to novel low toxicity anti-fouling agents therefor. One of the earliest need for performance-oriented coatings was in the marine environment. Early formulation were designed around known toxins, such as copper and mercury compounds Nineteenth Century marine coatings typically used creosote and natural drying oi formulations bearing the toxins. For ship bottoms, presently, anti-fouling compound based on copper and tin commonly are incorporated into somewhat water- sensitiv binders to afford gradual break-down of the film to permit a sustained release of th "poison". This required self-erosion property necessitates frequent repainting of shi bottoms, depending upon location and severity of exposure conditions. Today's anti-fouling coatings use two general leaching mechanisms, dependin on the type of resin matrix selected, soluble or insoluble. The insoluble-matrix typ leaves a resinous skeleton intact as the toxicant particles are removed by dissolving int solution in seawater. This also is called the contact type because it depends upon th toxicant migrating to the surface and entering solution by making contact with seawate Since the resins are somewhat water-permeable, the toxic particles may diffuse throug the semi-permeable coating, and as one particle dissolves, another is exposed t seawater. The contact type contains several times more toxicant than the soluble type The resulting thicker films of toxicant provide a longer service life to the anti-foulin topcoats. As a general rule, the insoluble-matrix type of paint does not contain a extended pigment, and the geometry of the dry film requires high toxicant loadings (52 to 74% by volume) to ensure the G12O particles will be in continuous contact with eac other. Below the level of cubic packing (52%), the resin will encase the CU2O particle and prevent solution; above the level of hexagonal packing (74%), the coating will b too resin-poor to maintain film integrity. These figures may vary somewhat in actua practice, and it is common to adjust the leaching rate and the effective range of toxican loading (e.g. by the addition of rosin or other natural resins). In common practice, bot natural resins and extender pigments are frequently used. When high levels of rosin ar used and high errosion might be expected, tougheners such as ester gum, ethy cellulose, and modified rubbers are added. (Paint Handbook, G.E. Weismantel McGraw-Hill, New York, New York, pp 14-43 and 14-44; and R.J. Dick, Marin Paints, Chapter 14). With respect to the toxins presently used in marine anti-fouling paints, rec U.S. federal legislation has severely restricted the use of organo-tin anti-fouling age Toxicity concerns appear to be a prime motivation behind this recent legislation. Pr proposals include, for example, Japanese Patents 56156202 and 52117425 report use of a combination of a napthoquinone and a thiuram disulphide in order to obtain a fouling activity, while Japanese Patent 63243067 proposes the use of diphenylamin Despite these proposals, there still is a substantial need in the anti-fouling arena for ne low toxicity anti-fouling coatings, caulks, and the like. Broad Statement of the Invention The present invention is addressed to a curable, marine anti-fouling compositi of a thermoplastic or thermosetting binder, solvent, non-tin, organb anti-fouling age and optionally conventional additives, e.g. leaching agents, opacifying pigments, e The anti-fouling agents are found in preferentially-concentrated domains (hereinaft often referred to as "PCD" or "PCDs") in the cured compositions. The PCDs can termed non-homogeneous, phase-separated, or incompatible in the system. The art te used in describing the PCDs of anti-fouling agents is not limitative of the invention the disclosure herein will demonstate. Preferably, PCDs are created by forming oligomeric adduct of the anti-fouling agent which adduct is formed into PCDs upon t curing of the composition. Additional techniques for forming PCDs of anti-fouli agent will be revealed herein. The present invention also is addressed to the use of new, low toxicity an fouling agents which comprise pesticide or herbicide compounds having a χ value between about 0.01 and 3, a Z value for vinyl or aromatic compounds of between abo 0.01 and 0.08, and an LD50 value of greater than 200 mg/kg against rats or mice. Su pesticide or algicide compounds broadly can be selected from heterocyclic compound aromatic compounds substituted with heteroatom substituents, various ami compounds, carbocyclic vinyl ether ketones, certain phospho compounds, certai polychlorinated carbocyclic and acyclic compounds, certain chlorinated carbocycl carboxylates, antimony tartrate, boric acid, and cupric oleate. Exemplary aromat compounds include diaromatic compounds linked with a sigma bond or with a carbon heteroatom linkage, fused aromatic rings, and mono-aromatic compounds. Advantages of the present invention include the ability to formulate marine an fouling compositions which contain low toxicity anti-fouling agents. Another advantag is the ability to formulate marine anti-fouling coating compositions wherein the lo toxicity anti-fouling agents display improved effectiveness by virtue of being formed i PCDs. These and other advantages will be readily apparent to those skilled in the based upon the disclosure contained herein.

Detailed Description of the Invention With the curtailment in permissible use of organo-tin anti-fouling agents due their human toxicity characteristics, the art truly needs to enable anti-fouling agen which exhibit low human toxicity characteristics. Once such agents are identified, th must be compatible with remaining formulation ingredients in marine coatings and oth marine compositions. Also, these low toxicity anti-fouling agents must display effica characteristics making them practical. Use of the non-tin, organo anti-fouling agents in marine composition will provide a modicum of protection to the substrate to which t composition is applied, yet enhanced, long-term protection is desired. Unexpectedly, was discovered that enhanced activity for extended periods of time could be achieved controlling the physical form in which the anti-fouling agents were presented in t cured marine compositions. Phase separation was the term initially used to define suc physical form. Later, the term "preferentially-concentrated domains" was adopted due the variety of techniques developed for achieving the desired physical form of the an fouling agents. Thus, islands, pools, or domains where the anti-fouling agen concentrate are created in the cured composition. Such domains typically will be the si of from about 0.3 μ to 500 μ (micrometers). - Techniques for achieving anti-fouling PCDs initially focused on chemicall linking the anti-fouling agent with an oligomer or polymer that phase-separated in th cured composition. This technique has the additional advantage in preventing the ant fouling agent from prematurely being leached from the cured composition resulting i loss of anti-fouling effectiveness. Other techniques envisioned include, for exampl dispersing an anti-fouling agent soluble (or compatible) with a compound whic compound itself is incompatible or domain-forming in the continuous phase of th composition. Such incompatible compound forms discrete domains in the cure composition which domains are enriched in the anti-fouling agent compared to th remainding continuous phase of the cured composition. Besides chemically linking th anti-fouling agent with an oligomer or polymer, the anti-fouling agent could complex o otherwise associate with a compound incompatible with the continuous phase of th composition. So long as PCDs of the anti-fouling agent are formed in the cure composition, the precepts of the present invention have been practiced. Conventional non-tin, organo anti-fouling agents may be used in the presen invention for forming PCDs thereof. The preferred non-tin anti-fouling agents useful i the present invention, however, broadly are selected from compounds which hav exhibited terrestrial biologic activity, e.g. known herbicides and pesticides. For presen purposes., herbicides are to be interpreted broadly as including not only compound which selectively and/or broadly kill various plant life, but also include various plan growth regulators, algicides, and the like. Pesticides, for present purposes, also shoul be broadly interpreted as compounds which are selectively and/or broadly toxic t harmful plant infestations, such as acaricides. These compounds, however, mu exhibit low toxicity to humans. For present purposes, "low toxicity to humans" i determined when the LD50 value is greater than 200 mg/kg against rats or mice. Within the broad spectrum of biologically active compounds described abov these compounds also must possess a χ factor of between about 0.01 and 3, and a value for vinyl or aromatic compounds of between 0.01 and 0.08. The χ factor is base upon the McGinniss predictive relationship as defined in Organic Coatings in Piasti Chemistry,. Vols. 39 and 46, pp 529-534 and 214-223, respectively (1978 and 198 respectively). The McGinniss predictive relationship defines the χ factor as a weig fraction of heteroatoms contained in the monomer or in the monomer repeat unit of a oligomer or polymer. The McGinniss predictive relationship defines the Z parameter a the weight fraction of π electrons contained in the monomer or in the monomer repe unit of an oligomer or polymer (e.g. π electron density of aromatic or viny compounds). Biologically-active compounds (as defined herein) that possess a χ facto and Z parameter within the ranges defined herein, and possess the requisite LD50 valu will be compounds which display anti-fouling characteristics in marine coatings. Though such compounds will exhibit anti-fouling characteristics, not all may b totally acceptable for all applications such as, for example, some high performanc marine coatings requirements, e.g. submarine exterior coatings. Nevertheless, th compounds will possess anti-fouling characteristics and low toxicity to humans whic makes their identification significant in the art's efforts at replacing conventional organo tin anti-fouling agents. The following biologically active compounds illustrate the LD50 values, factor, and Z parameter requirements possessed by the disclosed organo anti-foulin agents/reactants of the present invention and are offered as illustrative of the precepts o the present invention.

Their diminished toxicity to humans is a decide benefit compared to conventional organo-tin anti-fouling agents. Broadly, the low toxicity anti-fouling agents of the present invention can described as biologically active terrestrial compounds (e.g. pesticides and herbicide that are heterocyclic, aromatic with heteroatomic substituents, amino compounds, an carbocyclic ketone vinyl ethers. The aromatic compounds can be further identified mono-aromatic, fused aromatic ring compounds, and diaromatic compounds linked wit a sigma bond or with a carbon or divalent heteroatomic substituent. In addition to th ring compounds, hetero-substituted aliphatic compounds that are biologically active an possess the requisite χ value and Z parameter also may find use as anti-fouling agents i accordance with the precepts of the present invention. Additionally, compounds whic do not quite fit any of the foregoing definitions also should be recognized as include within the scope of the anti-fouling agents of the present invention. These include bori acid which has been demonstrated to be quite active as an anti-fouling agent, as the dat will testify. Additional compounds include, for example, antimony tartrate and cupri oleate.

Linking of the anti-fouling agent with an oligomer or polymer can accomplished by a variety techniques, depending upon the available functionality of t anti-fouling agent. For example, ethylenic unsaturation in the anti-fouling agent can copolymerized with acrylate or other ethylenically unsaturated monomers in conventio fashion. See, for example, Acrylic Monomer, product literature, Dow Badisc Company, Form No. A-GB-101; Preparation, Properties and Uses of Acrylic Polyme product liturature, Rohm and Haas Company, Form CM-19 B/eh; and U.S. Pat. 4,566,962, the disclosures of which are expressly incorporated herein by referen Anti-fouling agents with reactive hydroxyl or other active hydrogen functionality (e.g NH, -NH2, -SH, or the like) can be reacted with a polyisocyanate for forming an an fouling agent adduct. See, for example, Macromolecular Synthesis, C.G. Overberg Editor, Vol. 1, pp 69-74, John Wiley & Sons, Inc., New York, New York (1963), t disclosure of which is expressly incorporated herein by reference. Additional reactio will be readily apparant to those skilled in such art, as stated above, depending upon t reactive functionality in the anti-fouling agent Additional techniques for forming PCDs include, for example, complexi (association or other mechanism) of the anti-fouling agent with another ingredient in t formulation, e.g., pigment, polymer or oligomer additive, or the like. Anoth technique involves the anti-fouling agent being relatively more miscible in discontinuous phase (or particles), than in the continuous phase of the coating. Agai PCDs would be formed. Regardless or the technique, so long as PCDs of the an fouling agent are formed in the fianl product, improved long-term anti-fouling activi will be expressed by the anti-fouling agents. The formulation of the marine compositions containing the anti-fouling agents the present invention is practiced in conventional fashion as those skilled in the a appreciate utilizing conventional film-forming binders appropriate for mari environments. Marine compositions broadly for present purposes include, for examp coatings, elastomers, sealants, caulks, grouts, concretes, and like polymeric structu appropriate for the marine environment The form of the marine composition can be a coating, as rigid or elastomeric (including foamaceous) objects, as a sealant or a three-dimensional configured structure such as villous trailing fingers in the exterior marine vessels. Conventional additives, organic solvents (including reactive solvents diluents), and the like are incorporated into the formulation. The proportion of a fouling agent generally is between about 1 and 20 weight percent by weight of t formulation. The following examples show how the present invention has been practiced should not be construed as limiting. In this application, all percentages and proportio are by weight and all units are in the metric system, unless otherwise expres indicated. Also, all citations are expressly incorporated herein by reference. EXAMPLES EXAMPLE 1 In order to bind an organic anti-fouling agent into a polymeric structure, a thr neck reaction flask fitted with a mechanical stirrer, thermometer, and reflux conden was charged with a polysulfide polymer (200 g of LP-3 polysulfide polymer, Thioko 1,2-dicyano, tetrachlorobenzene (100 g of Nopocide brand, Diamond Shamroc potassium hydroxide (80 g), and dimethyl sulfoxide (100 ml).

Preparation of this material is similar to that preparation described in Polymer Science, vol. 15, 427-446 (1955). Reaction production 45701-4 can represented conventionally below. It will be observed that the reaction product contai a hydroxyl group which could be reacted with isocyanate or other functionality for incorporation into a curable resin. EXAMPLE 4 To 1,4,5,6,7 ,7-hexachloro-5-norborene-2,3-dicarboxylic anhydride (37 g) w added hydroxyethyl methacrylate (37 ml). This reaction mixture was heated to 87° C f three hours to produce reaction product 45701-5 which can be represent conventionally as follows: EXAMPLE 5 Addition of a 10% solution of CuCl2 in ethanol to a 10% solution of hydroxyquinoline formed a dark brown complex immediately. This complex 45701 was washed with hexane and dried without further purification.

This mixture was heated to 90° for three hours until a clear solution was obtained. The product was used without an further purification. Reaction product 45701-8 can be illustrated conventionally below: EXAMPLE 9 Two different modified polymeric structures were prepared. Polymeric structur 45701-10 was prepared by adding DER 331 resin (11 g) to 2-mercaptobenzothiazole (1 g) dissolved in toluene solvent (35 ml). This reaction mixture was heated to 90" C three hours until a clear solution was obtained. The second polymeric structu identified as 45701-11 was prepared by the same reaction procedure utilizing morpholi in place of 2-mercaptobenzothiazole. Both structures can be represented conventional below: EXAMPLE 10 In order to demonstrate the affect which PCDs of organo anti-fouling displa anti-fouling formulations (Control Paint) were compounded as follows: TABLE 1 Test panels were 15.24 cm x 30.48 cm (6 in x 12 in) in dimension and we constructed of a white plastic top surface and a black plastic bottom surface. The te panels were coated on both sides with the two formulations above-tabulated at a fil thickness of about 5 mils dry. The test panels then were exposed horizontally with t white surface upward and the black surface downward in the ocean at Daytona Beac Florida, U.S.A. A control panel consisted of 12 wt-% triphenyl tin hydroxide dispers in a resinous vinyl binder (80 wt-parts of a vinyl chloride polymer, VAGH bran Union Carbide Corporation, New York, New York) reduced in methyl ethyl keto solvent to 50% solids content The following results were recorded.

As later examples will confirm, the polymeric anti-foulin agent was in the form of PCDs in the cured paint. EXAMPLE 11 The Control Paint of Example 10 was formulated with additional polymeric a as-is anti-fouling additives and evaluated as in Example 10, with the following resul being recorded: TABLE?

EXAMPLE 15 Testing of several additional anti-fouling agents in the paint formulatio described in Example 12 was conducted for 6 months and the results compared t several polymerized versions of the same anti-fouling agents, with the following result being recorded: TABLE 7 Anti-Fouling General Rating Panel # Agent 1 Mo. 4 Mos. 6 Mos. 6 Mos.* 5 13-A1 Eugenol** 0 13-A2 Eugenol** 0 0 0 0 0 0 4-6 0 4-6 0 0 0 0 *Free-radical polymerized version prepared as reported in Examples 2, 4, or 6 or urethane version prepared as reported in Example 2, depending on the functionality o the anti-fouling agent **Eugenol is 99% 4-allyl-2-methoxyphenol. 5 EXAMPLE 16 An epoxy resin system was examined for its ability to be modified so as t preferentially influence the concentration or location of an anti-fouling agent (No ocid N-96 , see Example 1) within its structure. A direct comparison was made between epoxy resin (EPON 828 epoxy resin, diglycidyl ether of bis-phenol A, Shell Chemic Company) and the same epoxy resin containing a domain structuring polymeric materi such as a polysulfide resin (LP-32 polysulfide resin, Thiokol Corporation). Bo systems contained the same anti-fouling agent The compositions formulated are s forth below: TABLE 8 Sample (g-) Ingredient Epon 828 9 6 9 LP-32 - 3 Hexachlorophene 1.41 1.29 Polymer of Nopocide N-96 and LP-32 polysulfide (3 parts LP-32 and 1.24 parts Nopocide) — — 1.7 Ancamine AD* HO 3Λ 5.10 *Amine hardner, 485 amine value, Pacific Anchor Corp. Sample 1 that contained only the hexachlorophene anti-fouling agent and not t domain creating polymer (LP-32 polysulfide), provided an even chlorine distributio throughout the surface of the sample. Sample 1 also showed no regular domain si structure present as can be seen by reference to Fig. 1. Sample 2, however, exhibited very unique regular domain size (less than 1 μ) structure or pattern which was created the LP-32 polysulfide polymer (see Fig. 2). Energy Dispersion Spectoscopy (EDS) analysis of the sample surface f chlorine from the hexachlorophene anti-fouling agent showed that there were tw distinct domains or regions where the chlorine could be found. Chlorine was identifie in both the sea-like structures and the small round island structures in the sample (Fi 2). What was unexpected, however, was the discovery that the chorine concentratio and, thus, the concentration of anti-fouling agent, was significantluy higher (48%) in t round island domains and lower (36%) in the sea-like domains of the sample. pictorial representation of these results is displayed in Fig.3. Similar results were observed for Sample 3. Sample 3 contained larger dom size structures (about 100 μ), and chlorine from the Nopocide was found only in t areas where the domain or island was located. Areas between the islands did not cont chlorine. A chlorine or sulfur density map of the sample surface follows the outline the domain structure (see Figs.4, 5, and 6). EXAMPLE 17 In this example, an unreacted toxicant was evaluated with respect to its ability preferentially concentrate in domains of another material created within a continuo polymeric binder or carier. For example, certain types of acrylic copolymers dispers in a polyvinyl chloride (PVC) polymer can create discrete domains wherein a toxica molecule can preferentially concentrate. In this case, the toxicant was the 3, dichloroanaline-based acrylate monomer of Example 2 (80 wt-% concentration, sha melting point at 180° C), the continuous phase was VAGH PVC polymer (see Examp 10), and the domain-creating polymer was a mixture of polyhydroxyethylmethacryla (10 wf-% concentration, melting point less than 250° C) and a polymer of a methacryl acid ester of an amino carbamate monomer (10 wt-% concentration, melting point great than 300° C). Scanning electron micrographs are shown at Figs. 7 and 8 for PVC containi 20 to 30 wt-% of the mixture set forth in Table 11. The domains created by t polymeric and unreacted monomer mixture in the PVC can be distinguished easil Surprisingly, the toxicant monomer molecules are preferentially concentrated with t acrylic ingredients which created the domains in the PVC binder. An oxygen densit map (oxygen is analyzed rather than chlorine because of the chlorine content of th binder) of the film surface (see Figs 9-12) clearly indicates that the only place oxyge resides is in the domains. Interestingly, the oxygen is not distributed in the domain voi or sea-like regions of the PVC. The oxygen maps clearly outline only thos regions/domains or islands where the toxicant molecules reside, and not in the sea continuous phase of the PVC. The light or bright areas in these figures are due to th presence of oxygen and the dark regions are due to the absence of oxygen. EXAMPLE 18 Sample 2 of Example 16 was prepared again, except that the hexachlorophen toxicant-was replaced by Nopocide N-96. Thus, a blend of domain-forming LP-3 polysulfide resin and the Nopocide is being evaluated with respect to the formation o PCDs of Nopocide. The cured epoxy resin system was subjected to SEM and E analysis with the results set forth at Figs. 13-15. Fig. 13 is the SEM micrograph of an area of the cured epoxy resin at 200 X. is evident that the LP-32 polysulfide polymer created discrete domains. Fig. 14 displa the EDS analysis of chlorine at 200 X, while Fig. 15 is for sulfur. A comparison of t two EDS maps reveals that chlorine and sulfur both are present at the same location the cured epoxy resin system. Chlorine comes from the Nopocide toxicant, while sul comes from the LP-32 polysulfide resin. Again, then, the formation of PCDs of no tin, organo anti-fouling agents is seen to have been achieved. Here, such formation due to the preferential formation of domains by the LP-32 polysulfide polymer with t concomitant preferential concentration of the toxicant with the polysulfide polymer.
