Embodiment 1-3

[0028] A kind of wear-resistant type UV curable coating, it by weight percentage, its each component is as shown in table 1:

[0029] Table 1

[0030]

[0031] The preparation method of the above-mentioned wear-resistant coating specifically comprises the following steps:

[0032] Weigh raw materials according to the formula of the above-mentioned wear-resistant coating, add nano-calcium carbonate powder, stabilizer and 30% ethyl acetate solvent into the container according to the weight percentage, stir at 1500r / min for 10-20min, and then ultrasonically 10-30min, then add anti-fingerprint additive and stir for 10-20min at 1500r / min, then add leveling agent and stir for 10-20min at 1500r / min, ultrasonic for 10-20min; , nine-official urethane acrylate and 30% isopropanol solvent are mixed evenly. Mix the two evenly, add a photoinitiator and stir for 10-30min under the condition of 1500r / min rotating speed to obtain the wear-resistant UV curable coating.

Abstract

The invention relates to a low-cost high-wear-resistance UV-curing coating and a preparation method and application thereof. The low-cost high-wear-resistance UV-curing coating comprises the followingcomponents in percentage by weight: 20-35% of hexafunctional urethane acrylate, 3-8% of nona-functional to pentadeca-functional urethane acrylate, 0.7-1% of nanopowder; 0.5-1% of an anti-fingerprintauxiliary agent, 0.3-1% of a leveling agent, 0.2-2% of a stabilizer, 0.5%-2% of a photoinitiator and 50%-75% of a solvent. The wear-resistant UV-curing coating is applied to the PMMA surface of a PMMA / PC composite substrate in a shower coating, spray coating or manual coating manner so as to enhance the wear resistance of the surface of a PMMA / PC plate. The low-cost high-wear-resistance UV-curingcoating can form a tough coating layer on the surface of the PMMA / PC composite substrate after UV curing, has good adhesive force on the PMMA / PC composite substrate, high surface hardness, good abrasion resistance and low cost, can effectively prevent a product from scratches, and shows the characteristics of good hydrophobicity and oleophobicity and easiness in cleaning.

Description

technical field [0001] The invention relates to the field of ultraviolet curing coatings, in particular to a low-cost and high wear-resistant UV curing coating used on the surface of PMMA / PC composite substrates, as well as its preparation method and application. Background technique [0002] With the advent of the 5G era, metal mobile phone back covers are gradually being replaced by plastic. PMMA / PC composite material has high transparency, and can obtain visual vitrification effect through surface treatment, so it is the best choice to replace metal. Different from the current hotter plastic alloys, PMMA / PC composite board is a composite material made by co-extruding two raw materials, PMMA and PC. One side of the PMMA / PC composite board is made of PMMA, which has high hardness and wear resistance, and is used for the outer layer of the mobile phone cover; the other side is made of PC, which is softer and used as the inner layer to improve the overall toughness of the ma...
