Title:
POLYURETHANE RESIN RAW MATERIAL KIT, POLYURETHANE RESIN, ELASTIC MOLDING AND MANUFACTURING METHOD OF POLYURETHANE RESIN
Document Type and Number:
Japanese Patent JP2023115948
Kind Code:
A
Abstract:
To provide a polyurethane raw material kit capable of suppressing an internal defect of an elastic molding even when manufacturing a thick elastic molding, a polyurethane resin capable of suppressing an internal defect of an elastic molding even when a thick elastic molding is manufactured, an elastic molding containing the polyurethane resin, and a manufacturing method of a polyurethane resin capable of manufacturing a polyurethane resin capable of suppressing an internal defect of an elastic molding even when manufacturing a thick elastic molding.SOLUTION: A polyurethane resin raw material kit includes a main agent containing an isocyanate group-terminated prepolymer and a curing agent containing a chain extender. The isocyanate group-terminated prepolymer is a reaction product of the polyisocyanate component and the polyol component. The main agent and/or curing agent includes an organometallic catalyst and acetylacetone. A content of acetylacetone is 4 to 16 times the content of the organometallic catalyst.SELECTED DRAWING: None
