Abstract
The invention discloses an improved anti-UV scratching resistant paint. The paint is composed of the following raw materials in parts by weight: 0.6 to 1.4 parts of styrene, 3.5 to 5.4 parts of dihydroxy polymethyl vinyl siloxane, 2.2 to 4.4 parts of sodium-based bentonite, 2.5 to 4.5 parts of molybdenum disulfide, 3.4 to 6.6 parts of thickening agent, 2.6 to 3.8 parts of dioctyl phthalate, 1.5 to 2.5 parts of titanium dioxide, 5.8 to 7.8 parts of water, 0.2 to 0.5 part of filling material, and 0.6 to 0.9 part of film-forming auxiliary agent. The provided paint is a UV-cured scratching resistant paint that can be applied to window membrane and window protective membrane. The raw materials are easily-available, and the paint has excellent stability, so the industrial promotion and application is easy to perform. Furthermore, the paint has the characteristics of fast curing speed and simple preparation technology, and the production cost can be largely reduced. The coating formed by the paint has the characteristics of moderate hardness and good light transmittance.
Description
technical field [0001] The invention relates to a coating, in particular to an improved anti-ultraviolet and scratch-resistant coating, which belongs to the field of coatings. Background technique [0002] Scratch-resistant coating is a kind of thin-film coating, which has the characteristics of high hardness, wear resistance, and good light transmission. Film forming operation. Among them, the ultraviolet light curing method has the advantages of environmental protection, energy saving, and high efficiency. Scratch-resistant coatings are widely used in automotive solar film, automotive explosion-proof film, LCD display protective film, camera lens protective film, etc. However, the hardness of existing scratch-resistant coatings on the market is generally lower than 2H. Some scratch-resistant coatings have a hardness higher than 2H, but their transparency is not high, and they do not have the function of anti-ultraviolet rays, so they are not suitable for the requirement...
