Super-abrasion-resistant anti-fouling UV-cured coating and preparation method and application thereof

Abstract

The invention discloses super-abrasion-resistant anti-fouling UV-cured coating. The super-abrasion-resistant anti-fouling UV-cured coating comprises A component clear varnish and B component abrasion-resistant matting paste; the A component clear varnish is mainly prepared from the following raw materials: organosilicone polyurethane acrylate oligomer, polyurethane acrylate, epoxy acrylate, an acrylate monomer, an organic solvent, an nitiator and a leveling agent; and the B component abrasion-resistant matting paste is mainly prepared from the following raw materials: organosilicone polyurethane acrylate oligomer, a silane coupling agent, high-hardness powder, matt powder, an organic solvent, a dispersant, an anti-settling agent and an antifoaming agent. According to the super-abrasion-resistant anti-fouling UV-cured coating, the organosilicone polyurethane acrylate oligomer is introduced into the UV-cured coating, thus resin has the low surface tension, the good anti-fouling propertyis given to a coating coat, super-high hardness and abrasion resistance are given to a paint film, and durability of the anti-fouling effect of the finish paint coating can be achieved.

Description

technical field [0001] The invention belongs to the field of ultraviolet curing coatings, in particular to a super wear-resistant and antifouling UV curing coating and its preparation method and application. Background technique [0002] With the development of industrial technology, the 5G era is approaching. The materials of mobile phone casings have changed from plastic to metal, and now they are non-metallic. At the same time, people have higher and higher requirements for the appearance and performance of such electronic products. At present, the processing technology of mobile phone shells is mainly PVD coating and ribbon transfer printing. The process requirements and costs are difficult to control, and mass production is very difficult. Using the spraying process, the equipment is easy to operate, high in efficiency, and easier to achieve mass production. The use of spraying technology requires spraying coatings to have good construction performance and physical and...

AI Technical Summary

Problems solved by technology

Many manufacturers have been committed to wear-resistant, stain-resistant, and high-hardness UV-curable coatings. However, their wear resistance can be achieved by adding high-hardness inorganic materials (silica powder, ceramic powder, alumina, etc.) and physically mixing with the resin system. As a result, the combination fastness of inorganic materials and organic coatings is limited, and the hardness of ordinary inorganic materials used in coatings is limited (Mohs hardness is less than 9), which leads to wear-resistant, scratch-resistant and susceptible to abrasion on the surface of the coating, which is not enough to protect the surface Free from scratching, oil sticking and tarnishing
