▎ 摘　　要

NOVELTY - An acrylic emulsion comprises 20-40 parts mass methyl methacrylate, 10-30 parts mass styrene, 20-30 parts mass butyl acrylate, 10-20 parts mass hydroxyethyl acrylate, 1-10 parts mass emulsifier, 0.1-5 parts mass initiator, 0.1-5 parts mass aqueous ammonia, 0.1-5 parts mass graphene dispersion and 10-50 parts mass water. USE - Acrylic emulsion. ADVANTAGE - The acrylic emulsion has strong hardness , water resistance and good anti-corrosion and rust-proof ability by modifying graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of acrylic emulsion which involves adding methyl methacrylate, styrene, butyl acrylate, hydroxyethyl acrylate, emulsifier, initiator, aqueous ammonia, graphene dispersion and water into reaction vessel, stirring, dispersing, adding aqueous ammonia, adjusting the pH and filtering.
