Title:
THERMOSETTING FOAM WITH IMPROVED THERMAL INSULATION AND FLAME RETARDANCY, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/027726
Kind Code:
A1
Abstract:
Provided is a thermosetting foam comprising: a polyisocyanurate foam formed by polymerizing a polyol-based compound and an isocyanate-based compound; a nucleating agent; and a flame retardant, wherein the thermal decomposition initiation temperature of the thermosetting foam measured by thermogravimetric analysis is 310 ℃ or higher. In addition, provided is a method for preparing a thermosetting foam having the thermal decomposition initiation temperature measured by thermogravimetric analysis of 310 ℃ or higher, comprising the steps of: mixing a polyol-based compound and a nucleating agent; adding a flame retardant to the mixture of the polyol-based compound and the nucleating agent; stirring an isocyanate-based compound with the mixture obtained by adding the flame retardant thereto to polymerize a polyisocyanurate.
