▎ 摘　　要

NOVELTY - Composition comprises isocyanate-containing urethane acrylate UV resin, graphene powder, monofunctional reactive diluent, defoamer, leveling agent, photoinitiator and wetting dispersion agent. USE - The composition is useful in the field of UV-moisture dual curing corrosion-resistant coating (claimed). ADVANTAGE - The composition contains isocyanate-containing urethane acrylate UV resin, which is moisture-curing/UV-curing resin, and thus ensures moisture curing and UV curing of prepared product. The product prepared using the composition has improved hardness, adhesion, scratch resistance and corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the composition, comprising (i) mixing monofunctional reactive diluent, wetting dispersion agent and graphene powder, stirring and homogenizing to obtain graphene slurry, (ii) mixing isocyanate-containing urethane acrylate UV resin with monofunctional reactive diluent, defoamer and leveling agent, stirring to obtain first product, (iii) mixing the first product with the graphene slurry, carrying out first dispersion and second dispersion in sequence to obtain second product, where the dispersion speed of the first dispersion is less than that of the second dispersion, and (iv) mixing the second product with photoinitiator, stirring, allowing to stand for defoaming, and then filtering to obtain final product.
