Problems solved by technology

Therefore, coating additives are an important component material of coating products, and have been widely used. Its addition can not only avoid many coating defects and coating film defects, but also make the production and construction process of coatings easy to control. , but currently there are many kinds of coating additives, but they are all additives with a single function, which cannot improve the paintability, dispersibility and thickening of the coating at the same time, so how to improve the multiple properties of the additives needs to be further improved

Abstract

The invention discloses a coating auxiliary agent which is prepared from the following raw materials in parts by weight: 12-20 parts of sodium polystyrenesulfonate, 6-10 parts of aluminium phosphate,3-6 parts of titanium powder, 6-9 parts of ethylene glycol, 5-10 parts of carboxymethylcellulose, 10-15 parts of nano zinc oxide, 8-16 parts of polyacrylic acid, 2.5-5 parts of epoxy chloropropane and1-2 parts of an alkaline substance. The alkaline substance is a composition of one or more of sodium hydroxide, ammonia, triethylamine and triphenylphosphine. The coating auxiliary agent is simple informula and low in cost, has a good coating property, improves the dispersibility and thickness of a coating, improves the coating production process and the coating storage property, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of additives, in particular to a coating additive. Background technique [0002] Coating additives are an indispensable component of coatings. They can improve production processes, maintain storage stability, improve construction conditions, and improve product quality. They are additives with special effects. Reasonable and correct selection of additives can reduce costs and improve economic benefits. Therefore, coating additives are an important component material of coating products, and have been widely used. Its addition can not only avoid many coating defects and coating film defects, but also make the production and construction process of coatings easy to control. , but at present there are many kinds of paint additives, but they are all single-function additives, which cannot improve the paintability, dispersibility and thickening of paint at the same time, so how to improve the multiple performan...
