ABSTRACT:
Polymerizable unsaturated polyester resin syrups can be extended with aqueous alkali metal silicate in compositions containing from 0.1 to 10.0 parts by weight of aqueous alkali metal silicate for each part by weight of the unsaturated polyester resin syrup. The preferred alkali metal silicate is aqueous sodium silicate. Compositions further can be extended (a) by the addition of reactive fillers such as metal oxides or hydrated metallic salts; (b) by the addition of inert fillers such as clay, silica, glass fibers, perlite; or (c) by the addition of both (a) and (b). The fillers also may include fibrous reinforcing materials such as dispersed glass fibers, randomly oriented fiber mats, wound filaments and woven fabrics. The fillers may be present in amounts from about 0.1 to about 5 times the combined weight of aqueous alkali metal silicate and unsaturated polyester resin syrup.
The compositions can be employed in coatings, laminates, cast articles, molded articles, or other shaped articles. The polymerized products are resistant to combustion, have a low fuel content, a low flame spread and are useful thermal insulating materials. The products furthermore have a low smoke content. When exposed to fire, the organic content of these materials is burned and the residual inorganic content is converted to a refractory ceramic material which resists further thermal deterioration and functions as a thermal insulator to resist thermal transfer.
