Title:
POLYURETHANE RESIN AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/257317
Kind Code:
A1
Abstract:
The present invention provides a polyurethane resin and a preparation method therefor. The preparation method for the polyurethane resin comprises mixing a first component and a second component to prepare the polyurethane resin, wherein the first component is formed by mixing at least one organic polyol, an acrylate monomer, and a catalyst, the second component is formed by mixing an isocyanate and an initiator, and the weight ratio of the first component to the second component is controlled to be 100:(60-90), making the prepared polyurethane resin be a polyurethane resin having an operable time of 50-200 minutes while the viscosity is 20-300 mPa.s at a temperature of 25°C, and a thermal deformation temperature of the polyurethane resin during curing at a temperature of 70°C for 4 hours is greater than 60°C.
