Title: Improvements in or relating to protective coatings and drier compositions for use inprotective coating materials
IPC: C09F9/00
Filed: 1931-07-13
Abstract: Hydrocarbon resins are prepared from the unsaturated hydrocarbons of cracked distillate, or from a diolefine and an olefine, or from a diolefine and a substituted benzene, or from an olefine a diolefine and a substituted benzene, by reacting these materials in the presence of a metallic halide catalyst such as an anhydrous aluminium halide.  The reaction is ended by neutralizing the mixture, the catalyst is separated, and the resinous product is hardened.ALSO:Phenol, beta-naphthol, or chlor-phenol are incorporated in metallic driers with solvents miscible with drying oils, and the resulting drier composition is used in paints and varnishes to form a non-crystallizing fast-drying coating material.  By using beta-naphthol in this way, tung oil may be used with any type of resin and prolonged heating of the tung oil for bodying is unnecessary.  The use of phenol or chlor-phenol in addition to beta-naphthol prevents darkening of the film on drying.  The metallic drier and the phenolic body may be stored as a dry mixture and dissolved when required for use.  Solvents specified are denatured ethyl alcohol, amyl and butyl alcohols, mineral spirits, solvent naphtha, benzol, toluol, and turpentine.  A mixed solvent may be used.  The drier and the phenol may be dissolved in different solvents and the solutions mixed.  Driers specified are the resinates, linoleates, naphthalene sulphonates and homologues of the latter, of cobalt, lead, manganese, iron, cerium and p  vanadium, and mixtures of such driers may be used.  Proportions are specified.  The examples describe the use of beta-naphthol with cobalt resinate and butyl alcohol; beta-naphthol with manganese linoleate and ethyl alcohol; beta-naphthol with a mixture of lead and manganese driers of the naphthalene sulphonate type and ethyl alcohol; and beta-naphthol with phenol or chlor-phenol, and with lead and manganese linoleates, solvent naphtha, and ethyl alcohol, with or without turpentine.  The driers are suitable for varnishes containing a neutral hydrocarbon resin made from the unsaturated hydrocarbons of cracked distillate, or from a diolefine and an olefine, or from a diolefine and a substituted benzene, or from an olefine, a diolefine and a substituted benzene, by reacting these materials in the presence of a metallic halide catalyst such as an anhydrous aluminium halide.  In preparing such resins, the reaction is ended by neutralizing the mixture, the catalyst is separated, and the resinous product is hardened.  Varnish is prepared by bodying tung oil at 230-320 DEG  C. for about 5 minutes, adding the neutral hydrocarbon resin in solution, adding the solution of metallic drier and phenolic substance, and thinning.
