摘要:A preparation method for an acrylic polymer leveling agent, comprising: polymerizing different types of (meth)acrylic acid low-carbon alkyl ester monomers, olefin monomers, and vinyl silicone resins in a polyhydroxy polyether solvent under the action of an initiator to obtain polymer 1; polymerizing different types of hydroxyalkyl acrylates in the polyhydroxy polyether solvent under the action of the initiator to obtain polymer 2; and finally compounding polymer 1 and polymer 2 to obtain a leveling agent. The introduction of the vinyl silicone resins in polymer 1 promotes the wetting of a substrate by the leveling agent and eliminates shrinkage cavities, to form a low-surface-energy interface on the surface of a coating, thereby controlling the surface state of the coating and avoiding problems such as orange peel, shrinkage cavities, flooding and floating, sagging, and brush marks on the surface of the coating. The introduction of the polyhydroxy polyether solvent in the polymer synthesis process improves the compatibility and leveling performance of the leveling agent.
