Title:
ISOCYANATE-CONTAINING COMPOSITION AND TWO-PART REACTION TYPE POLYURETHANE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/244650
Kind Code:
A1
Abstract:
The present invention improves, in a polyurethane resin composition containing an inorganic filler, the miscibility of an isocyanate-containing composition with respect to a polyol-containing composition while suppressing the reduction in storage stability of the isocyanate-containing composition. An isocyanate-containing composition according to an embodiment of the present invention is to be used as a polyisocyanate component for a two-part reaction type polyurethane resin composition, and contains: an isocyanate group-containing urethane prepolymer obtained by causing a reaction between a polyisocyanate and a polyol having an average functional group number of 2.5 or less and a weight average molecular weight of 700 or more; an inorganic filler; a plasticizing agent; and at least one selected from the group consisting of compounds represented by general formula (1) and/or compounds represented by general formula (3).
