A METHOD FOR PREPARING POLYURETHANE NANO COMPOSITE AND POLYURETHANE NANO COMPOSITE PREPARED BY THE SAME

摘要

PURPOSE: A producing method of a polyurethane nano composite, and the polyurethane nano composite produced therefrom are provided to prevent material degradation by using a coherence force of a solid additive. CONSTITUTION: A producing method of a polyurethane nano composite comprises the following steps: mixing a polyol containing compound with a liquefied silane-based nucleant; stirring the mixture; and obtaining a polyurethane by mixing a diisocyanate group containing compound with the mixture. The liquefied silane-based nucleant is a compound in which more than one hydrogen atom of a silane group is substituted with a methyl group. The polyol is either polyester polyol or polyether polyol.
