Exterior wall coating

Abstract

The invention provides an exterior wall coating. The coating is prepared from deionized water, propylene glycol, hydroxyethylcellulose, silica sand powder, dispersant, nonionic surfactant, defoamer, lignin, kieselguhr, potassium tripolyphosphate, titanium white, zinc oxide, nepheline syenite powder, coalescent solvent, preservative and acrylic copolymerizing emulsion. The exterior wall coating has the characteristics of high durability, high toughness, high alkali resistance and the like.

Description

technical field

[0001] The invention belongs to the field of building materials and provides an exterior wall paint with high durability, high flexibility and high alkali resistance. technical background

[0002] Exterior wall coatings are building materials, for which mechanical properties, durability, fire-resistance, health, flexibility, alkali resistance, waterproof, appearance, production, construction and environmental protection are usually considered. For the development of high-performance exterior wall coatings, many inventors have proposed solutions.

[0003] For example, the Chinese patent "CN1308103 Latex exterior wall paint and its preparation method" provides a latex exterior wall paint, the main components are pigments and fillers, nanoparticles, additives A, additives B, polymer emulsion, additives C, water, etc. , after dispersing, stirring, mixing, grinding, toning, etc., the product is prepared, which can absorb and reflect ultraviolet light and prolong ...
