▎ 摘  要

NOVELTY - Preparation of shape-memory modified polyurethane resin comprises adding graphene oxide to the reaction vessel, adding alkyd resin and dispersant, stirring, heating at 180-240 degrees C while stirring for 1-2 hours to obtain alkyd resin-graphene polymer, adding polyurethane prepolymer into the reactor, stirring, dispersing, adding chain extender and alkyd resin-graphene polymer, heating at 75-85 degrees C for 1-2 hours and cooling. USE - Method for preparing shape-memory modified polyurethane resin (claimed). ADVANTAGE - The product has temperature and pressure dual-response weather-resistance property.
