Problems solved by technology

[0003] At present, waterproof coatings do not have good elongation and breaking strength, and are poor in acid resistance, alkali resistance and weather resistance.
In addition, the existing common waterproof coatings have poor impermeability, weak adhesion, poor flexibility, and poor overall elasticity.
Therefore, in some military projects, mechanical pits, tunnels, swimming pools, pools, basements, water supply pipe drainage and irrigation sluices pasted with tiles, and concrete structures such as roofs, toilets, balconies, and pipeline joints, although they are coated with conventional waterproof coatings, , once the concrete cracks, there will still be water leakage at the cracks

Abstract

The invention discloses acrylic ester waterproof paint, which is prepared from the following components by a content ratio: 20-30 parts of titanium dioxide, 10-20 parts of talcum powder, 10-20 parts of ground calcium carbonate, 1-2 parts of a dispersing agent, 40-80 parts of emulsion, 2-4 parts of dibutyl ester, 3-6 parts of cellulose and 10-20 parts of deionized water. After a coating film is dried, a continuous coating is formed; the coating has good elongation and breaking strength, good acid resistance and alkali resistance as well as excellent weather resistance, and is convenient for construction and free from environmental pollution. The paint is aging-resistant and long in service life, can be made into various colors according to the needs, has effects of being decorative and waterproof, and is non-toxic, odorless and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of paint processing, and in particular relates to an acrylate waterproof paint. Background technique [0002] The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding Corresponding additives are viscous liquids prepared with organic solvents or water, which can cover the surface of objects for protection, decoration, and marking industries. [0003] At present, waterproof coatings do not have good elongation and breaking strength, and have poor acid resistance, alkali resistance, and weather resistance. In addition, the existing common waterproof coatings have poor impermeability, weak cohesive force, poor flexibility, and poor overall elasticity. Therefore, in some military projects, mechanical pits, tunnels,...
