Problems solved by technology

[0002] At present, traditional coatings are generally used for the decoration of building walls. Most of the coatings are limited to high elasticity, poor water resistance and water resistance, low tensile strength, and general adhesion. Generally, they are only used for interior decoration. Nowadays, people pay more and more attention to the living environment, so the outdoor decoration is getting more and more attention. However, because it is not water-resistant and not waterproof, the paint film will peel off as a whole after being washed by r

Abstract

The invention discloses a waterproof acid and alkali resistant paint. The waterproof acid and alkali resistant paint is prepared from the following raw materials in parts by weight: 15-40 parts of acrylic emulsion, 3-10 parts of polyurethane, 0.5-5 parts of rosin modified phenolic resin, 0.5-2 parts of triethoxyisobutylsilane, 5-10 parts of filler, 1-5 parts of hydroquinone, 10-30 parts of water, 2-4 parts of methyl isobutyl ketone, 0.5-2 parts of n-butyl acetate, 20-40 parts of heavy calcium carbonate, and 4-11 parts of expanded perlite micro powder. The waterproof acid and alkali resistant paint has acid and alkali resistance, good wear-resisting property, excellent waterproof performance and low cost.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a waterproof, acid and alkali resistant coating. Background technique [0002] At present, traditional coatings are generally used for the decoration of building walls. Most of the coatings are limited to high elasticity, poor water resistance and water resistance, low tensile strength, and general adhesion. Generally, they are only used for interior decoration. Nowadays, people pay more and more attention to the living environment, so the outdoor decoration is getting more and more attention. However, because it is not water-resistant and not waterproof, the paint film will peel off as a whole after being washed by rainwater, which looks unattractive. At present, acid rain The impact is getting bigger and bigger, which makes the requirements for the paint coating on the outer layer of the building higher and higher. The waterproof and anti-seepage of the building is related to ...
