First Claim
Patent Images
1. The process for the production of polyisocyanate-polyester silicate plastic by mixing the following components:
- (a) 20 to 70 parts by weight of an organic polyisocyanate or polythiocyanate;
(b) 3 to 80 parts by weight of an unsaturated polyester resin;
(c) catalytic amount of a free-radical initiator to polymerize the unsaturated polyester resin;
(d) 0% to 100% by weight of an inorganic water-binding component, said water-binding component being capable of absorbing water to form a solid or a gel, and based on the total weight of components (a) and (b);
(e) 10% to 100% by weight of a polyisocyanate curing agent, based on the total weight of components (a), (b) and (d), but with the proviso that the polyisocyanate curing agent is added last.

Abstract
A polyisocyanate is reacted with an unsaturated polyester containing a vinyl monomer and a water-binding agent, then cured with water containing an oxidated silicon compound and an initiator such as a peroxide to produce solid or cellular solid inorganic-organic plastic.
