Abstract

The invention discloses an anti-yellowing priming paint which consists of the following components in parts by weight: 40-50 parts of acrylic resin, 10-15 parts of pentachlorodiphenyl, 10-15 parts of flax oil, 5-10 parts of titanium dioxide, 20-25 parts of a filling material, 1-2 parts of bentonite, 1-5 parts of an auxiliary and 1-15 parts of a solvent. The provided anti-yellowing priming paint has extremely strong anti-yellowing capability, and the anti-yellowing performance is obviously superior to that of the conventional priming paint product, so that the quality of the product using the provided priming paint is improved, and the provided priming paint has a wide market prospect.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an anti-yellowing primer. Background technique [0002] A primer is a paint that is applied directly to a surface to serve as a solid base for a topcoat. The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat and increase the fullness of the topcoat. The primer can also ensure the uniform absorption of the topcoat. At the same time, the primer can also provide the paint system with alkali resistance, Anti-corrosion and other functions, so that the paint system can play the best effect. [0003] At present, the yellowing resistance of the primers sold in the market is generally poor. After the surface of the material is coated with the existing primer, after a period of ultraviolet radiation, the primer will appear yellowing. [0004] Therefore, prior art needs further improvement. Contents of the invention [0005] The object of the pr...
