Title:
RESIN COMPOSITION, POLYURETHANE MATERIAL, POLYURETHANE COMPOSITE MATERIAL, AND PREPARATION METHODS
Document Type and Number:
WIPO Patent Application WO/2023/284618
Kind Code:
A1
Abstract:
The present invention provides a resin composition comprising an isocyanate component, a reactive component, and a free radical initiator. In the reactive component, the sum of the average number of acrylate double bonds and active hydrogen contained in each molecule is not less than 2.1. The acrylate double bonds are double bonds on acrylic acid groups or on methacrylic acid groups, and can help improve product performance, and effectively reduce the water sensitivity of the resin composition, thereby avoiding, to the greatest extent, a foaming problem in the subsequent production, preparation, and processing process of the composite material. The present invention further provides a polyurethane material, which is prepared from the resin composition, a polyurethane composite material comprising the polyurethane material, and preparation methods for the resin composition, the polyurethane material, and the polyurethane composite material.
