Problems solved by technology

[0002] With the rapid development of the construction industry, its supporting coating technology is also constantly updated. Waterproof coating is one of the most popular coatings in modern society. It not only requires good waterproof performance on the wall, but also has Good flame retardant effect and high-strength adhesion ability, but the existing waterproof coating is very strong and at the same time, and due to the need for viscosity and anti-oxidation performance, it does not meet the requirements in terms of environmental protection, and contains a large amount of harmful substances such as formaldehyde

Abstract

The invention relates to special waterproof paint for a building and a preparation method thereof. The special waterproof paint is prepared from the following ingredients in parts by weight: 4 to 6 parts of polyurethane, 15 to 20 parts of acrylic emulsion, 3 to 5 parts of titanium dioxide, 3 to 4 parts of polyvinylether, 2 to 3 parts of hydrophobic silica, 6 to 10 parts of mica powder, 10 to 15 parts of styrene-acrylate emulsion, 3 to 5 parts of sodium carboxymethyl cellulose, 2 to 4 parts of diacetone acrylamide, 3 to 5 parts of aromatic polyamides, 2 to 3 parts of putty powder and 25 to 30 parts of ethyl alcohol. The special waterproof paint has the advantages that the materials can be easily obtained; the anti-ultraviolet radiation is effectively realized; the oxidization resistance, aging resistance, insulation and flame retardance are realized; a surface coating is formed for achieving the waterproof effect; the paint can also seep into the substrate to form crystals so as to prevent water passing; the duplex waterproof effect is achieved; the bonding performance is high; the dispersion is uniform; the smooth degree is high; one-step coating is performed; the work efficiency is improved; the cost is reduced; the curing time is short; the application range is wide.

Description

Technical field [0001] The invention relates to the field of waterproof coatings, in particular to a special waterproof coating for buildings and a preparation method thereof. Background technique [0002] With the rapid development of the construction industry, the matching coating technology is constantly updated. Waterproof coating is one of the most popular coatings in modern society. It not only requires good waterproof performance on the wall, but also has Good flame-retardant effect and high-strength adhesion ability, but the existing waterproof coatings are very strong and take into account at the same time, and due to the needs of viscosity and oxidation resistance, they cannot meet the environmental protection requirements and contain a large amount of formaldehyde and other harmful substances . Summary of the invention [0003] The purpose of the present invention is to provide a special waterproof coating for buildings and a preparation method thereof in order to over...
