  • High heat resistant and high scratch resistant water-based polyurethane and manufacturing method thereof
    Patent number: 11053336
    Abstract: A method for manufacturing high heat resistant and high scratch resistant water-based polyurethane, which can improve the mechanical strength and water resistance of water-based polyurethane by using acrylate graft modification, is provided. In particular, 2-hydroxyethyl acrylate (2-HEA), methyl methacrylate (MMA), ethyl acrylate (EA), acrylic acid (AA), glycidyl methacrylate (GMA) and triallyl isocyanuric acid ester (TAIC) are used to dilute polyurethane prepolymer. As a result, the prepolymer has a good dispersing effect, and further, waterborne bridging agent and cellulose nanofiber are added to the water-based polyurethane to obtain water-based polyurethane which has high heat resistance and scratch resistance.
