Scouring-resistant paint and preparation method thereof

Abstract

The invention discloses a scouring-resistant paint. The paint consists of the following raw materials in parts by weight: 75-85 parts of water-borne acrylic emulsion, 20-25 parts of styrene-acrylate emulsion, 8-10 parts of hydroxypropyl methyl cellulose, 5-7 parts of white carbon black, 2-3 parts of tributyl citrate, 1-3 parts of glycerol, 1-2 parts of diamylamine, 1-2 parts of sodium polyacrylate, 1-2 parts of poly (butyl acrylate), 2-3 parts of sodium hexametaphosphate, 0.2-0.4 part of dimethicone, 1-3 parts of hydroquinone, 10-20 parts of deionized water, 0.8-1 part of aminopropyltriethoxysilane and 10-14 parts of a compound modifier. The produced paint has the advantages of hard paint film, good glossiness, strong shock resistance, difficult cracking, soft texture, strong decorative performance, high weather resistance, scouring resistance, strong adhesion, long service life, no peculiar smell, no heavy metals such as mercury and lead and no formaldehyde volatile matters; and the paint satisfies the technical requirements of environment-friendly paints, and the added compound modifier replaces the conventional titanium dioxide.

Description

technical field [0001] The invention mainly relates to a paint, in particular to a scrub-resistant paint and a preparation method thereof. Background technique [0002] In recent years, water-based, environmentally friendly, multi-functional and high-performance have become the development trend of building exterior wall coatings. With the improvement of people's living standards, the functions of exterior wall coatings such as waterproof, mildew proof, and insect resistance have gradually become popular among the public. Therefore, higher requirements are put forward for the decorative effect of coatings. External wall coatings require water resistance, self-cleaning properties, hard and smooth paint films, and dirt will fall off as soon as they are washed. [0003] At present, the exterior wall coatings used in my country are mainly based on acrylic emulsion. Water-based acrylic coatings have the advantages of moderate cost, excellent weather resistance, good adjustabi...

Problems solved by technology

[0004] However, the acrylic paints currently on the domestic market have disadvantages such as low gloss, poor adhesion, poor cold resistance, intolerant to water, water vapor, acid and alkali, salt solutions and organic polar solvents, poor elasticity at room temperature, and poor wear resistance. High temperature is easy to stick back, low temperature is easy to be brittle, resulting in easy cracking and peeling of the paint, and rainwater is easy to penetrate into the wall and corrode the wall, which not only affects the decoration of the building, but also reduces the service life of the building
