POLYISOCYANURATE FOAM AND PRODUCTS COMPRISING THE SAME

摘要

PURPOSE: Polyisocyanate foam is provided to improve excellent adhesion, insulating performance and mechanical properties using four kinds of mixed polyols which are different from each other. CONSTITUTION: Polyisocyanate foam is formed by foaming a foam composition which comprises an isocyanate component, a polyol component, and a foaming agent. The polyol component comprises 40-70 wt% of a polyol obtained by reacting glycol to terephthalate, 10-30 wt% of a polyol obtained by reacting glycol to adipic acid, 10-20 wt% of a polyol obtained by reacting one selected from ethylene oxide and propylene oxide, and 10-30 wt% of a polyol obtained by reacting glycol to phthalic anhydride.
