Abstract

The present invention provides an environmentally-friendly, fully recyclable composite mining screen which has sufficient rigidity to replace existing metal and metal covered plastic mining screens. The inventive composite screen insert contains stiff reinforcing fibers (glass, carbon, etc.) and exhibits the rigidity of metal and metal-covered plastic mining screen inserts so as to minimize deflection in use. The inventive mining screen is also completely recyclable because at the end of its useful life, the broken and used screen can be ground into polymer particles and the particles incorporated into new screens or other parts.

Abstract

Provided is a process for producing a polyisocyanurate comprising: trimerizing an aliphatic polyisocyanate with a trimerization catalyst in the presence of a thermally decomposable acid at a molar ratio of acid to catalyst of from 0.1 to 10, wherein the polyisocyanurate has a greater pot life than the pot life of the polyisocyanurate not containing the thermally decomposable acid. Polyisocyanurates made according to the inventive process lengthen the pot life of pultrusion composite formulations made therefrom without affecting the reactivity of the formulations. The pultrusion composite formulations of the invention may be cured and pultruded to yield a variety of products such as wind turbine blades, yacht shells, window frames, door frames, ladder frames, telegraph pole cross arms, tent poles, solar cell frames, solar cell backsheets, radomes, highway guard rails, floor boards, pipes, telegraph poles, auto trunks, luggage holders, engine covers, golf clubs, tennis poles, badminton poles, bicycle frames, surfboards, and snowboards.
