Abstract

The invention relates to a paint and particularly relates to a matt coating paint. The matt coating paint is prepared from the following components in percentage by weight: 35-45% of modified alkyd resin, 20-30% of tung oil, 10-16% of an epoxy resin composition, 2-5% of terephthalic acid, 12-16% of palm kernelate, 5-8% of ethyl methacrylate, 1-3% of matt acrylic paint, 5-10% of polyvinyl butyral, 3-5% of a defoaming agent, 2-4% of an emulsifying agent and the balance of a paint thinner. A high net structure formed by drying a painted film is less in possibility of ageing, soft and firm, friction-resistant, good in water resistance, alkali-resistant, dampness-heat-resisting, mildew-resisting, excellent in salt spray resistance, mineral-oil-resisting and good in alcohol solvent resistance.

Description

technical field [0001] The invention relates to a paint, especially a matte film paint. Background technique [0002] Due to the influence of external conditions such as sunlight, temperature changes, wind and rain, the coating film will appear a series of aging phenomena such as fading, discoloration, cracking, chalking and strength decline. At present, the corrosion resistance of many coatings is not strong, which cannot meet the increasing needs of people. 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 coat...
