Problems solved by technology

Due to the influence of construction equipment and curing conditions, architectural powder coatings are limited in the application of architectural exterior walls
In addition, the coating of inorganic silicate gel film-forming substances has poor adhesion, no elasticity, easy to crack, and not easy to efflorescence and other problems.

Abstract

The invention discloses building external wall powder paint, which comprises the following ingredients: silicate cement, high-alumina cement, ethylene terpolymer polymer, hydroxyethyl methyl cellulose, defoaming agents, water reducing agents, waterproof agents, kaolin, coarse whiting, alkali-resistant glass fiber, natural fillings and inorganic pigment. The building external wall powder paint hasthe beneficial effects that the white silicate cement is used as film forming materials, the acetic ether or ethylene terpolymer powder is used for modifying the inorganic silicate cement, the pigment and the natural inorganic decoration fillings are matched, a coating has good attaching force and strong decoration performance through organic silicon functional auxiliary agents, the building external wall powder paint has the characteristics of good ageing resistance and chemical resistance performance of an inorganic coating and also has ventilation, waterproof and strain-proof functions, and the problem of influence on the coating appearance caused by silicate saltpetering is solved. The building external wall powder paint has the advantages that the product preparation and the construction are simple, the water is added for stirring when the paint is used, the paint can be constructed in a way of spray coating, brush coating and scrapping coating, the practicability is high, and the application range is wide.

Description

technical field [0001] The invention relates to a building coating, in particular to a building exterior wall powder coating and a preparation method thereof. Background technique [0002] In recent years, the construction industry has gradually developed into a pillar industry of the national economy, and the proportion of architectural coatings in coatings has also increased year by year, accounting for 40% of the total coatings, of which the application of exterior wall decorative coatings has exceeded 35% of architectural coatings . Architectural coatings are directly related to people's health and living environment, reflecting people's living standards. With the development of modern life, culture and social economy, people have higher requirements for architectural coatings, which determines the development trend of architectural coatings in the future. [0003] Powder coating is a 100% solid content, solvent-free powder coating. Due to no solvent pollution, 100% f...
