[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

Abstract
The invention relates to an exterior wall coating material of a high-stability paint film. The exterior wall coating material is prepared from the following raw materials in parts by weight: 90-100 parts of water-based acrylic emulsion, 10-15 parts of mica powder, 10-16 parts of styrene-acrylic emulsion, 2-3 parts of ethylene glycol, 1-2 parts of alcohol ester twelve-film-forming additive, 1-2 parts of nano-zinc oxide, 1-2 parts of poly-butyl acrylate, 3-4 parts of sodium tripolyphosphate, 1-2 parts of water glass of 28-35 baume degree, 10-20 parts of deionized water, 1-2 parts of ethylene diamine tetra methylene phosphonic acid sodium, 0.8-1 parts of 1,2-double (triethoxy silicon-based) ethane, 0.3-0.5 parts of fatty alcohol sodium tripolyphosphate and 15-20 parts of compound modifier. The coating material has the advantages of hard paint film, good glossiness, strong impact force, soft texture, strong decorativeness, high weather resistance and scrubbing resistance, strong adhesive force and long service life, is not easy to craze, does not have special smell, heavy metals of mercury, lead, and the like and formaldehyde volatiles and accords with the technical requirements of environmental protection coating materials. Conventional titanium dioxide is replaced by the added compound modifier so that the surface glossiness of the paint film is improved and the production cost is saved.
Description
technical field [0001] The invention mainly relates to a paint, in particular to an exterior wall paint with a high stable paint film 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 weath...
