Problems solved by technology

[0003] At present, the biggest defect of many AG anti-glare coatings is that they feel rough and have poor anti-fingerprint and anti-friction properties.
The reason for this kind of problem is generally that the matting powder added has not been processed, and the particle size is small. During the curing process, the matting powder is easy to migrate to the surface of the paint film, making the surface of the paint film rough and causing bad hand feeling and wear resistance. Poor performance, and the high surface energy of general matting powder also makes it poor in anti-fouling and anti-fingerprint effect

Abstract

The invention discloses an anti-dazzle anti-fingerprint wear-resistant hardening liquid with rubber hand feeling, and a preparation method thereof. The hardening liquid comprises, by weight, 40-50 parts of organic fluorine-silicon special modified polyurethane acrylic resin, 10-15 parts of special modified UV matte polyurethane acrylic resin, 5-10 parts of an acrylic monomer, 1-5 parts of a photoinitiator, 1-2 parts of fluorine-containing acrylic compound resin, 1-3 parts of a rubber skin feeling auxiliary agent, 4-5 parts of matting powder, 3-4 parts of wear-resistant powder, 1-2 parts of an anti-settling agent, 1-2 parts of a wetting dispersant and 20-30 parts of a solvent. The hardening liquid obtained by the invention is high in hardness, good in hand feeling, good in wear resistance and excellent in anti-fingerprint effect, can meet the higher requirements of the market on anti-glare hardening liquid, can be used for spraying and also can be used for shower coating, and compared with spraying, the shower coating can greatly reduce the production cost, avoid environmental pollution and relieve harm to human bodies.

Description

technical field [0001] The invention relates to the field of mobile phones, tablet computers and other 3C electronic back covers mainly based on PMMA / PC composite plates, in particular to a rubber skin-feeling anti-glare anti-fingerprint anti-fingerprint wear-resistant hardening liquid and a preparation method thereof. Background technique [0002] Anti-glare coatings generally add matting powder or wax paste to the coating to make the surface of the coating uneven during the curing film formation process, thereby increasing the scattering of light and reducing reflection, reducing the gloss of the paint film , in order to achieve the effect of anti-glare (Anti-glare). [0003] At present, the biggest defect of many AG anti-glare coatings is that they feel rough and have poor anti-fingerprint and anti-friction properties. The reason for this kind of problem is generally that the matting powder added has not been processed, and the particle size is small. During the curing p...
