Problems solved by technology

The curing mechanism of UV coatings is mainly the free copolymerization of acrylate functional groups. After curing, there are a large number of polar functional groups on the surface of the paint film. It spreads on the surface, so the surface of the UV coating is not very resistant to staining
[0004] In recent years, researchers have successively proposed to add anti-fingerprint additives to the existing UV coatings to solve the problem that the surface of the paint film is not stain-resistant. For example, a Chinese invention patent with application number CN200580014573. The perfluoropolyether modified acrylate with staining effect can improve the stain

Abstract

The invention relates to high-wear-resistance UV resin with an anti-fingerprint function and a preparation method of the high-wear-resistance UV resin. Raw materials of the resin comprise the following components: an isocyanate mixture, perfluoropolyether alcohol containing a hydroxyl group at one end, a mixture of single-end-carbon hydroxyl polysiloxane and double-end-carbon hydroxyl polysiloxane, linear polyester glycol free of fluorine and silicon, hydroxyl acrylate containing a polyurethane structure and a polyurethane reaction catalyst. According to the invention, perfluoropolyether and an organic silicon chain segment are introduced into a molecular chain of an UV resin polymer at the same time through reaction among the components, and the friction coefficient and the surface energyof the surface of the resin are reduced by utilizing the synergistic effect of fluorine-silicon molecules, so the prepared UV resin has good fingerprint resistance and wear resistance; and meanwhile,the hydrogen bond content of the molecular chain is increased by introducing carbamate with relatively high content into the molecular chain of the UV resin polymer, so the cohesive energy of the molecular chain is further improved, and the wear resistance of the UV resin is further improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high wear-resistant UV resin with an anti-fingerprint function, and further to a method for preparing the UV resin. Background technique [0002] With the rapid development of 5G technology, the utilization rate of plastic materials on surfaces such as electronic communication equipment is gradually increasing, and there is a great tendency to replace existing glass, ceramics and metals. However, the plastic surface is not wear-resistant and easy to stick to dirt, so it needs to be treated with wear-resistant and anti-fouling in practical applications. [0003] UV coatings belong to purple curing coatings, which are mainly composed of oligomers, reactive diluents, photoinitiators and additives. They have high hardness and good wear resistance. Coating on the surface of plastics can improve their resistance Moreover, UV coatings have the characteristics of low-tempera...
