Abstract

The invention discloses an energy-saving and environmentally-friendly coating and relates to the field of chemical products to mainly solve the problem that a traditional coating is easy to crack andpeel off in a natural environment. The coating comprises the following raw materials (by weight): 35-51 parts of polyamide resin, 24-38 parts of phenolic resin, 12-23 parts of fatty amine, 8-17 partsof glycerin, 5-11 parts of agar, 14-25 parts of closed-cell perlite, 2-7 parts of vacuum glass beads, and 1.6-3.3 parts of a dispersant. The coating of the invention has high thermal stability, and can be effectively avoided from cracking and peeling off under natural conditions such as exposure to sunlight and wind blowing, thus guaranteeing an effective service life. Meanwhile, the coating is green and environmentally-friendly. The volatile quantity of harmful substances can be greatly reduced, the environment is protected, thus avoiding from affecting the body health of surrounding people.

Description

technical field [0001] The invention relates to the field of chemical products, in particular to an energy-saving and environment-friendly paint and a preparation method thereof. Background technique [0002] Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. [0003] With the development of science and technology, there are more and more types of coatings, among which the development of protective coatings is particularly rapid, but the existing coatings still have certain defects, such as cracking, peeling, etc. At the same time, the phenomenon will volatilize more harmful gases, which will cause environmental pollution and also easily affect the health of su...
