▎ 摘  要

NOVELTY - A modified acrylic resin solution comprises 30-50 parts mass polysiloxane acrylate, 2-5 parts mass hydroxyalkyl(meth)acrylate, 1-5 parts mass unsaturated carbon-carbon double bond-containing silane coupling agent, 30-60 parts mass (meth)acrylate, 2-5 parts mass mercapto-containing silane coupling agent, 10-20 parts mass hydroxyl-containing ester diluent, 0.1-0.5 part mass carbon hydroxyl modified graphene oxide and 0.5-2 parts mass initiator. USE - Modified acrylic resin solution used for anti-corrosive coating used for stainless steel surface protection (all claimed). ADVANTAGE - The modified acrylic resin solution improves anticorrosive performance and prolong the service life of stainless steel in a high salt environment. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of modified acrylic resin solution, which involves mixing polysiloxane acrylate, hydroxyalkyl(meth)acrylate, (meth)acrylate, hydroxy-containing diluent and carbon hydroxyl-modified graphene oxide to obtain mixture (A), mixing mixture (A) with unsaturated carbon-carbon double bond-containing silane coupling agent and mercapto-containing silane coupling agent in protective atmosphere to obtain mixture (B) and adding initiator to mixture (B); and (2) anti-corrosive coating, which comprises component (A) comprising 100 parts mass modified acrylic resin solution, 10-40 parts mass inorganic filler, 0.2-1 part mass leveling agent, 0.5-1 part mass defoaming agent, 0-3 parts mass dispersant, 0-1 part mass pigment and 0-1 part mass thixotropic agent and component (B) comprising curing agent, where mass ratio of component (A) and component (B) is 100:(2-90).
