Embodiment 1～5

[0034] Examples 1-5 respectively provide a high wear-resistant, anti-fingerprint UV-curable coating composition, the components and contents of which are shown in Table 1.

[0035] The mixed solvent shown is a mixed solvent of butyl acetate, n-propyl acetate, isopropanol, and propylene glycol methyl ether with a mass ratio of 2:3:3:1.

[0036] The preparation method of described coating composition comprises the steps:

[0037] A. Place the high-functionality acrylate resin, fluorine-modified acrylate oligomer, acrylate monomer, nanoparticle dispersion, and solvent in a reaction kettle, stir and mix evenly;

[0038] B, add described photoinitiator, stir until dissolving completely;

[0039] C. Add the auxiliary agent and stir until it is uniformly dispersed to obtain the high wear-resistant and anti-fingerprint UV-curable coating composition.

Abstract

The invention provides an ultraviolet curing coating composition with high wear resistance and fingerprint resistance and a preparation method thereof. The composition is prepared from the following components in parts by weight: 30-50 parts of high-functionality acrylate resin, 5-15 parts of fluorine-modified acrylate oligomer, 5-20 parts of an acrylate monomer, 5-15 parts of nanoparticle dispersion liquid, 5-9 parts of a photoinitiator, 0.05-2 parts of an auxiliary agent and 30-50 parts of a solvent. Compared with the prior art, the steel wool of the prepared ultraviolet curing coating composition is excellent in wear resistance and has fingerprint resistance and hand sweat resistance; and the coating has high hardness, is suitable for surface protection of plastic base materials, has excellent comprehensive performance, and can be applied to the related fields of mobile phone plastic rear covers, mobile phone films and the like.

Description

technical field [0001] The invention relates to the field of ultraviolet light curing coatings, in particular to a high wear-resistant and anti-fingerprint ultraviolet light curing coating composition and a preparation method thereof. Background technique [0002] In recent years, mobile phone communication technology has developed rapidly. With the mature application of 5G technology, mobile phone communication equipment has been continuously updated and developed, especially in the field of mobile phone back covers. The original metal body has a certain impact on the transmission of 5G signals. Signal quality However, the back cover of glass and plastic mobile phones has received more attention. Due to the advantages of diversified performance, easy processing and low price, plastic substrates have received a lot of attention from many mobile phone manufacturers in the field of low-end mobile phones. Pay attention to. [0003] Conventional UV-curable coatings have a certa...
