Additive for coating used in public place

Abstract

The invention provides an additive for a coating used in a public place and relates to the technical field of coating additives. The additive comprises the following constituents in percentage by weight: 10-15 percent of nano-alumina, 15-20 percent of nano-silica, 8-10 percent of nano-zinc oxide, 5-10 percent of a drier and a solvent in balance amount, wherein the drier is one or two of zinc isoocatanoate and dibutyltin dilaurate; the solvent is one or more of butyl acetate, dimethyl carbonate and isopropanol. The additive provided by the invention has the advantages that the problems that the coating used in the public place is single in manufacturing function, cannot have good weather resistance, rapid drying performance, an anti-bacterial function and a self-cleaning function simultaneously, so that the problem that high public health security cannot be ensured is solved.

Description

technical field [0001] The invention relates to the technical field of paint additives, in particular to a paint additive used in public places. Background technique [0002] Coatings such as paints used in public places are required to have good weather resistance, that is, UV resistance, water resistance, heat resistance, acid rain resistance, etc., and also require no pollution to the environment, such as no irritating odor, etc., and are used in places where they are in contact with people , such as benches in parks, etc., are also required to dry quickly after use to avoid touching tourists. At the same time, the coating is required to have certain antibacterial and self-cleaning functions to ensure public health safety in public places; by adding functional additives to the coating It is a relatively common practice to improve the performance of coatings, but the coatings used in public places in the prior art have high manufacturing costs and single functions, and can...
