METHOD FOR PREPARING POLYISOCYANURATE FOAM USING A LIQUID SILANE-BASED COMPOUND AS A LIQUID NUCLEATING AGENT AND POLYISOCYANURATE FOAM PREPARED BY THE SAME

摘要

PURPOSE: A method for preparing polyisocyanurate foam using a liquid nucleating agent and polyisocyanurate foam prepared by the same are provided to reduce the size of foamed cell using a liquid nucleating agent while using a foaming agent and to improve compressive strength and flexural strength.;CONSTITUTION: A method for preparing polyisocyanurate foam comprises a step of polymerizing a polyol-based compound and an isocyanate-based compound. A liquid silane compound is used as a nucleating agent for form formation. The content of the liquid silane compound is 0.5 ~ 10 parts by weight based on 100 parts by weight of the polyol-based compound.;COPYRIGHT KIPO 2011
