POLYISOCYANURATE FOAM AND PRODUCTS COMPRISING THE SAME |
摘要 |
PURPOSE: Polyisocyanurate foam is provided to have excellent insulating performance and excellent adhesion while having a good heat-insulating performance and mechanical properties. CONSTITUTION: Polyisocyanurate is formed by foaming a foam composition which comprises an isocyanate component, a polyol component and a foaming agent. The NCO/OH ratio of the isocyanate component and the polyol component is 1.3-2.5. The polyol component is obtained by reacting 40-70 wt% of a polyol which is obtained by reacting glycol to terephthalic acid, 10-30 wt% of a polyol which is obtained by reacting glycol to adipic acid, 10-20 wt% of a polyol obtained by reacting one or more selected from ethylene oxide and propylene oxide to sorbitol, and 10-30 wt% of a polyol obtained by reacting glycol to a phthalic anhydride.
