Abstract
The invention relates to a multifunctional leveling agent for powder coatings. The multifunctional leveling agent for powder coating provided by the present invention comprises a leveling agent monomer and a brightening agent monomer, and the mass ratio of the leveling agent monomer and the brightening agent monomer is 1:2 to 3:4, and the leveling agent The monomer is composed of acrylate monomer and α-methylstyrene according to the mass ratio of 80:20~90:10. The brightener monomer is composed of acrylate monomer: methacrylate monomer: α-methylstyrene It is composed according to the mass ratio of 5:70:25~8:80:12. The multifunctional leveling agent for powder coatings provided by the present invention is added with a high softening point substance α-methylstyrene, thereby increasing the respective softening points of the leveling agent and the brightening agent, and then mixing in proportion to obtain a material with suitable elasticity and toughness, so that the flow The leveling agent and the brightening agent can better achieve their respective functions, and take into account the characteristics of both the leveling agent and the brightening agent, which can reduce the production and application process, cost and energy consumption of the auxiliary agent.
Description
technical field [0001] The invention belongs to the field of powder coatings, in particular, the invention relates to a multifunctional leveling agent for powder coatings. Background technique [0002] Powder coating is a solid powder synthetic resin coating composed of solid resin, pigments, fillers and additives. Since it does not use solvents, it has the characteristics of harmlessness, high efficiency, resource saving and environmental protection. Leveling agent is a commonly used powder coating additive, it can promote the coating to form a flat, smooth and uniform coating film during the drying and film forming process; it can effectively reduce the surface tension of the coating liquid, improve the leveling and uniformity of the powder coating It can also improve the permeability of the coating solution, reduce the possibility of spots and marks when brushing, increase the coverage, and make the film formation uniform and natural. Brightener is a kind of powder coati...
