Abstract

The invention discloses a paint leveling agent which comprises the following components in parts by weight: 5-10 parts of butyl acrylate, 3-9 parts of polyether modified polysiloxane, 2-7 parts of tetrasodium pyrophosphate, 3-7 parts of sodium chloride, 4-9 parts of bamboo powder, 2-7 parts of low-temperature-curing polyester resin, 3-9 parts of epoxy resin and 5-10 parts of carbon black. The leveling agent has favorable leveling property and decorating property, accelerates and balances the volatilization of the solvent, can enhance the shining effect of the paint, can reduce the dust adsorption in the paint production process, enhances the release capacity of the coating solvent, inhibits the inter-coating dissolution action, prevents the paint from yellowing, and enhances the leveling property and hand feeling.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a paint leveling agent. Background technique [0002] Powder coatings and coatings have become one of the rapidly developing coating varieties due to their characteristics of resource saving, energy saving, pollution-free, high labor production efficiency and easy realization of automatic coating. Now it has become a recognized 4E type coating product that meets the requirements of high production efficiency, excellent film performance, eco-environmental protection and economy. [0003] In thermosetting powder coatings, leveling agent is one of the indispensable additives in the composition of powder coatings. Whether it is high-gloss, glossy, semi-gloss, matt or matt powder coatings, leveling agents must be added to powder coating formulations. Compared with liquid coatings, the leveling of powder coatings is much more difficult than that of liquid coatings, and th...
