▎ 摘　　要

NOVELTY - Preparing composite leveling agent comprises (i) mixing and stirring 40-50 pts. wt. acrylic monomers, 30-40 pts. wt. hydroxyalkyl acrylate, 3-5 pts. wt. graphene, and 1-3 pts. wt. initiator, heating, reacting, and uniformly dispersing to obtain graphene-supported acrylic resin, and(ii) compounding graphene-supported acrylic resin obtained in the step (i) with liquid metal of perfluoro-modified polyacrylic acid and gallium indium tin alloy to obtain composite leveling agent for powder coatings. USE - The agent is useful for powder coatings (claimed). ADVANTAGE - The agent is suitable for adding to epoxy resin and polyester thermosetting powder coatings.
