Problems solved by technology

[0005] However, water-based coatings will be oxidized by air or aged by ultraviolet rays during use, resulting in micronization, which reduces the service life. Moreover, during use, after a long time of use, the gloss will decrease, which will affect the appearance. and also cause the object to be susceptible to corrosion

Abstract

The invention discloses a coating additive for a waterborne coating. A formula of the coating additive for the waterborne coating comprises raw materials as follows: 20-25 parts of a substrate wetting agent, 5-15 parts of a dispersing agent, 10-25 parts of a defoaming agent, 6-12 parts of a thickening agent, 5-10 parts of a coalescing agent, 10-15 parts of nano zinc peroxide, 8-15 parts of an ultraviolet absorbent agent, 10-22 parts of an inorganic antibacterial agent, 12-16 parts of a mold inhibitor and 2-10 parts of a surfactant. The coating additive for the waterborne coating adopts a simple formula and has effects of mold prevention, bacteria killing, oxidation resistance and ultraviolet resistance; besides, the prepared finished product has a good anti-corrosion effect, and the thixotropy and the glossiness of the coating are improved.

Description

technical field [0001] The invention relates to the technical field of water-based paints, in particular to a paint additive for water-based paints. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. Water-based paints include water-soluble paints, water-diluted paints, and water-dispersible paints (latex paints). Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. Water-dilutable paint refers to the paint prepared by the post-emulsification emulsion as a film-former, so that the solvent-based resin is dissolved in an organic solvent, and then with the help of an emulsifier, the resin is dispersed in water to form an emulsion by strong mechanical stirring, which is called post-emulsification. Em...
