Antiaging water-resistant architectural paint and preparation method thereof

Abstract

The invention discloses an antiaging waterproof building paint and a preparation method thereof. The antiaging water-resistant architectural paint is prepared from the following raw materials in parts by weight: 35-50 parts of acrylate emulsion, 5-15 parts of polyvinyl alcohol, 5-10 parts of 2-methoxy-4-methylphenol, 5-15 parts of ethylene glycol, 3-8 parts of ethylene-vinyl acetate copolymer emulsion, 5-10 parts of titanium dioxide, 1-3 parts of sodium dodecylsulfate, 0.1-1 part of dimethyl silicone oil, 1-5 parts of propylene glycol methyl ether acetate, 0.1-1.0 part of antimicrobial agent and 0.1-1.0 part of ultraviolet absorbent. The types and consumptions of the ultraviolet absorbent and antimicrobial agent suitable for the external wall paint are selected according to reasonable proportioning, thereby enhancing the illumination aging resistance; and the paint has favorable antimicrobial property.

Description

technical field [0001] The invention relates to the field of paint technical materials, in particular to an anti-aging waterproof architectural paint and a preparation method thereof. Background technique [0002] Paint is a material that can be well bonded to the base material and form a complete and tough protective film on the surface of an object, called a paint. Paint and paint are the same concept. Paint is a customary name that people have used for a long time. After it was introduced into my country, it has been used in the construction industry. The role of coatings can be summarized into three aspects: protection, decoration, and special functions. The general composition of coatings: including film-forming substances, pigments and fillers, solvents, and additives. [0003] Architectural coatings have the functions of decoration, protection and habitability improvement. The proportions of various functions vary depending on the purpose of use. The decorative f...

Problems solved by technology

[0007] At present, the amount of acrylate elastic emulsion used as water-based wood coating is increasing day by day. Since acrylic emulsion is free radical polymerization, the molecular structure formed is linear, so the wood paint made of it has poor abrasion resistance and paint film resistance. Disadvantages of poor adhesion

In recent years, many researchers have carried out a lot of research work to further improve the performance of acrylate emulsions. The more common method is to introduce cross-linking monomers. At present, most of the emulsions on the market use acrylamide as a cross-linking agent. Introduced, played a certain cross-linking effect, but did not change the linear structure of the acrylic emulsion, so the performance improvement is not obvious
