The surfactant component of the present invention may be any surfactant capable of forming microcells during the making of the first layer In a preferred embodiment, the surfactant component comprises a fast soap, such as ammonium lauryl sulfate (ALS) (e.g. Stepanol AM; Stepan Chemicals, Northfield, Ill.) and sodium lauryl sulfate (SLS). Generally, a “fast soap” is a soap which is capable of efficiently modifying the surface tension of a solvent, such as water. However, other surfactants may also be used which are not characterized as fast soaps but which are capable of forming microcells. Fast soaps, such as ALS, form microcells that are resilient and are generally stable to the heat of processing. Surfactant-generated microcells are generally not stable at temperatures above 350° F. Additional components may be added to further stabilize the microcells, as further discussed below. However, if so desired, a surfactant which forms “weak” microcells may be used. The “weak” microcells may burst during processing to produce collapsed microcells which produce a less flexible composite material.
The gel catalyst component of the present invention may be any component known in the art which is capable of catalyzing gel formation. In a preferred embodiment, the gel catalyst is SSF-GEL available from Parachem (Dalton, Ga.). In addition, other catalysts may be added to promote vulcanization to provide permanent cross-linking and to thermoset the first layer which can enhance the strength of the surfactant-generated microcell structure. In a preferred embodiment of the present invention, UP-750 (a sulfur catalyst available from Tiarco, Dalton, Ga.) is such a catalyst. In addition, Octocure®-590, Octocure®-456 and Octocure®-462 (available from Tiarco, Dalton, Ga.) may also be used for this purpose.
In one embodiment of the invention, the binder/surfactant mixture is subjected to a roamer. The foamer acts to inject air into the mixture so that the surfactant forms microcells within the mixture. The foamer may comprise a tube-like component having a multitude of pins which are capable of rotating in opposing directions (e.g. some pins move clockwise and some move counterclockwise). The mixture of binder and surfactant is added to the foamer through a port on one side and, as it passes through the foamer, the pins rotate causing the introduction of air and the creation of surfactant-generated microcells. Additional air may also be introduced into the roamer at another port to further enhance surfactant-generated microcell formation. After surfactant-microcell generation, the gel catalyst may be added through a port of the foamer. The mixture may then be spread onto a substrate, such as a fiberglass mat. Alternatively, if no substrate is desired, the mixture may be spread onto a receiving platform, such as a steel tray to form a free-standing sheet. Whether applied to a substrate or a receiving platform, the material is then subjected to heat in an oven. Processing temperatures are preferably between about 280° F. to about 350° F. The heat of processing further enhances gel formation by causing the reaction to occur at a faster rate.
In a preferred embodiment, the surfactant-generated microcells are stable to the heat of processing. As noted, generally surfactant-generated micrcocells are not stable at temperatures above 350° F. The filler is added to the mixture together with the surfactant and binder and before the addition of the gel catalyst. Preferably, the surfactant-generated microcells are relatively small and uniform in size.
In the present invention, clay is a preferred filler because of its elongation properties (it has a low modulus), its abrasion resistance, its tear resistance, and its tensile strength. Moreover, clay is a good heat barrier; it does not disintegrate when an open flame (temperature ≧1500° F.) is applied directly to a first layer of the present invention that includes clay. In addition, clay provides a slick, elastic, glassy surface which exhibits flexibility. Furthermore, as noted, clay is inexpensive and thus can provide a low cost fabric material.
Examples of woven materials that may be useful in the present invention include continuous fiberglass veils, such as Pearlveil™ 110, Pearlveil™ 210, Curveil™ 120, Curveil™ 220, Flexiveil™ 130, Flexiveil™ 230 and Pultrudable veil (all available from Schmelzer Industries, Inc., Somerset, Ohio). The non-woven materials may be Airlaid (Precision Fabrics Group, North Carolina) and Spunbond (Freudenberg Non-Woven, North Carolina). Nonlimiting examples of filament materials include C, DE, G, H, K, M filaments (glass fiber filaments of differing thicknesses) of various grades, including electrical grade, chemical grade and high strength grade (all available from BFG Industries, Inc. of Greensboro, N.C.). As used herein, a fiberglass mat includes nonwoven and woven fiberglass mats. In one embodiment, the fiberglass mat is a non-woven mat which comprises from about 70-95% H glass filaments, from about 0-5% Evanite microglass at 4.5 microns, from about 0-15% polyester fiber (50/50 mix of ¼ inch and ½ inch length), and from about 5-10% acrylic based binder with a glass transition temperature (Tg) at 18° F.
