Problems solved by technology

In practical application, it is found that the formaldehyde purification efficiency of the coating reaches 86.8-88.2%, and the persistence of formaldehyde purification effect reaches 72.8-74.0%. The toluene purification efficiency reaches 52.1-54.2%, and the toluene purification effect persistence reaches 34.8-36.0%. Improvement, but people in modern society have higher requirements for quality of life, so higher requirements are put forward for more efficient and more environmentally friendly coatings

Abstract

The invention provides a preparation method of a formaldehyde adsorption water-based environmental protection coating. The preparation method includes the following steps that 1, styrene-acrylate resin liquid, pure acrylic emulsion, polyether-modified polysiloxane and poly(N-isopropylacrylamide)modified magnesium hydrate are added to deionized water, the mixture is heated and stirred to be uniform and filtered, and filtrate is obtained for use; 2, acrylate-styrene-vinyl acetate terpolymer, nanometer activated carbon, nanometer titania, calcined kaolin and an anion additive are added to a ball mill to be ground till the particle size is 60-80 nm, then the mixture is mixed and stirred, and a mixture is obtained; 3, the mixture obtained in step 2 and remaining hydroxyethyl cellulose, cellulose ether, 2-imidazolidone, 1-(2-hydroxyethyl)-2-imidazolidone, lauric acid and glycerin are added to the filtrate obtained in step 1, the mixture is mixed under the action of a high-speed blender and stirred for 30-40 minutes, then vinyl acetate-ethylene copolymer emulsion is added, the mixture stands still for 3-4 hours, and the formaldehyde adsorption water-based environmental protection coating is obtained.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a method for preparing formaldehyde-absorbing water-based environmental protection coatings. Background technique [0002] Paint is a chemical mixture paint that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called coating film, also known as paint film or coating.” It belongs to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compound. According to the classification of modern chemical products, coatings belong to fine chemical products....
