Description
Technical Field
The invention relates to an environment-friendly coating, in particular to an environment-friendly coating for a green building wall and a preparation method thereof.
Background
Paint (paint), which we commonly speak of as paint, is but one such. The coating is a liquid or solid material which can form a film under certain conditions and has the functions of protection, decoration or other special functions (insulation, rust prevention, mildew prevention, heat resistance and the like) when being coated on the surface of an object. Since the early coatings mostly used vegetable oils as the main raw material, they were also called paints. Synthetic resins have now replaced vegetable oils and are known as coatings. The coating is not liquid, and powder coating is a large category of coating. The paint belongs to organic chemical high molecular material, and the formed coating film belongs to high molecular compound type. According to the modern popular classification of chemical products, the coating belongs to fine chemical products. Modern coatings are gradually becoming a multifunctional engineering material, an important industry in the chemical industry. The main functions are four points: protecting, decorating and masking the defects and other special functions of the product, and improving the value of the product.
The coating applied to the exterior of the building wall at present can face the air in different shapes and colors due to long-term exposure, and the harmful substances can enter the room after the wall can not treat harmful gases and suspended particles because the wall is the first indoor protective line.
