Title:
POLYOL-BASED MIXED LIQUID COMPOSITION FOR PRODUCING HYDROCHLOROFUROOLEFIN FOAMED POLYURETHANE FOAM, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/239734
Kind Code:
A1
Abstract:
In the production of a hydrochlorofluoroolefin polyurethane foam using a known amine catalyst, there were problems in that a mixed liquid did not rapidly start the foaming reaction and that dripping occurred in a spraying method.　This polyol-based liquid composition, which is for producing a polyurethane foam and which includes (i) (A) a carbonate of an amine compound represented by general formula (1), (2), or (4), (ii) a foaming agent comprising (B) a hydrochlorofluoroolefin, and (iii) (C) a polyol, is used.
