Abstract

The invention relates to paint, in particular to paint with good gloss retention. The paint comprises the following components in percentage by weight: 12-18% of alkyd resin, 20-30% of tung oil, 10-16% of epoxy resin, 2-5% of terephthalic acid, 3-6% of acrylate modified alkyd resin, 12-16% of palm wax ester, 5-8% of methacrylic resin, 0.5-1% of isophthalic acid, 1-3% of propylene pigment, 3-6% of phthalic anhydride, 5-10% of polyvinyl butyral, 3-5% of an antifoaming agent, and the balance of a thinner. The paint has the advantages that the use is extensive, the properties are excellent, a high-density reticular structure is formed after a paint film is dried, the paint is not easy to age, the gloss retention is good, the property of resisting mineral oil and alcohols solvents is good, and the water resistance, the insulativity and the oil resistance of the paint are greatly improved after being torrefied.

Description

technical field [0001] The invention relates to a paint, especially a paint with good gloss retention. . Background technique [0002] Coating is a material that can be coated on the surface of an object by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. It belongs 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] The coating film will lose its original luster when it is exposed to light, and many coatings currently have poor gloss retention. Contents of the invention [0004] The present invention ...
