Abstract: The present invention discloses a modified graphene oxide UVLED light-cured polyurea coating and its preparation method. The modified graphene oxide UVLED light-curable polyurea coating includes component A and component B; said component A is obtained by reacting isocyanate compounds and amino-terminated compounds with unsaturated hydrocarbon compounds. Carbon-carbon double bond isocyanate prepolymer; the component B is a mixture of modified graphene oxide, amino-terminated compounds, photoinitiators, additives and solvents; the modified graphene oxide is composed of unsaturated carbon-carbon double The bond coupling agent is obtained by modifying graphene oxide. The paint film of the modified graphene oxide UVLED light-cured polyurea coating of the present invention has the advantages of high mechanical properties, strong adhesion, corrosion resistance, hydrophobicity, etc., during construction and curing, the curing energy is low, and the environment is friendly.
