Organo-Mineral Composite Materials Based on Sodium Liquid Glass, Tolylene-2,4-diisocyanate, Epoxy Oligomer, and Polyisocyanate

Resumo

Organo-mineral composite materials based on sodium liquid glass combined with tolylene-2,4-diisocyanate (TDI), polyisocyanate, and epoxy oligomer have been synthesized. When heated, the organic components of the composites form a polymer network through the trimerization reaction and TDI curing of the epoxy oligomer. The composite materials after heating to 130°C have a uniform structure. The resulting hybrid composite materials are not brittle and exhibit enhanced heat resistance as compared to common polyisocyanurate compositions. Hybrid composites can find wide application in various fields of engineering.
