Title:
BLOCKED POLYISOCYANATE COMPOSITION, PREPOLYMER COMPOSITION AND METHOD OF MANUFACTURING SAID COMPOSITIONS, AND THERMALLY DISSOCIABLE BLOCKING AGENT OF BLOCKED POLYISOCYANATE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2014/045620
Kind Code:
A1
Abstract:
The present invention imparts a low-temperature thermosetting property superior to that of a phenol resin prepolymer to a prepolymer that is a blend of a blocked polyisocyanate compound and a polyisocyanate reactive compound, and the generation of an unpleasant odor or toxic gas that affects the environment is suppressed during manufacturing or thermosetting, the thermoset plastic that results from the thermosetting is provided at a cost comparable to that of a phenol resin, and the generation of formaldehyde is suppressed. At least one selected from a group consisting of an alkali metal carbonate, an alkali metal hydrogencarbonate, an alkali metal percarbonate, an alkali metal phosphate, an alkali metal hydrogenphosphate, an alkali metal dihydrogenphosphate, an ammonium carbonate, an ammonium hydrogencarbonate, an ammonium percarbonate, an ammonium phosphate, an ammonium hydrogenphosphate, and an ammonium dihydrogenphosphate is used as a thermally dissociable blocking agent that reacts with the polyisocyanate compound and enables dissociation at a very low temperature.
