High performance aqueous exterior wall paint

Abstract

The invention relates to high performance aqueous exterior wall paint. The paint is composed of, by weight, the following raw materials: 100-115 parts of titanium dioxide, 80-90 parts of wollastonitepowder, 75-85 parts of calcium silicon powder, 3-4 parts of a dispersant, 20-22 parts of ethylene glycol, 300-310 parts of a pure acrylic emulsion, 160-180 parts of light calcium powder, 25-30 parts of bentonite, 4-5 parts of talc powder, 3-4 parts of the bentonite, 1-2 parts of hydroxypropyl methyl cellulose, 1-2 parts of a defoaming agent, 55-60 parts of a wetting agent, 25-28 parts of methanesiliconic acid sodium salt, and 250 parts of water. The paint has the characteristics of simple preparation, good usage effect, economical efficiency, strong stain-resistant capability, and good water resistance and alkali resistance, can effectively prevent mildew and cracking, and is suitable for wide popularization and application.

Description

technical field [0001] The invention belongs to the field of building materials and relates to exterior wall paint. Background technique [0002] With the rapid development of economic construction, there are more and more high-rise buildings, and the appearance decoration of buildings is becoming more and more important. Because it not only protects the wall, but also reflects the taste and style of the building. At present, most high-end buildings use ceramic tiles to decorate the exterior walls, which not only costs more, but also increases the load on the wall, and over time, the adhesive between the facing bricks and the wall will always age, and the facing bricks may fall and hurt people. Therefore, it is imperative to develop exterior wall coatings to replace ceramic tiles and mosaics. [0003] Although the development of exterior wall coatings in our country has a history of many years, the varieties of exterior wall coatings have increased year by year, and the qu...

Problems solved by technology

[0003] Although the development of exterior wall coatings in our country has a history of many years, the varieties of exterior wall coatings have increased year by year, and the quality has also continued to improve. However, due to the influence of production technology and process level, most of the products are low-grade exterior wall coatings. Weak staining ability, poor water and alkali resistance, easy to mold after rain; it is difficult to meet the requirements of modern architectural decoration, therefore, research and development of high-performance, high-quality architectural exterior wall coatings is the development trend of the coatings industry today
