Embodiment Construction

[0026] The present invention is described in further detail now in conjunction with embodiment.

[0027] UV bright coating with high wear resistance and high toughness is prepared by the following steps:

[0028] (1) each component is taken by weight;

[0029] (2) First mix polyurethane acrylate resin, polyester acrylate resin, acrylic acid monomer and mixed solvent evenly, then add leveling agent and photoinitiator, and mix evenly to obtain UV bright coating.

[0030] See Table 1 for details of the components and their weight percentages of Examples 1-5 and Comparative Examples 1-7.

[0031] Table 1

[0032]

[0033]

[0034] Among them, polyurethane acrylate resin and polyester acrylate resin can be selected from the products of American Corning Company, American Sartomer Company, Nippon Gosei, American Cytec, Guangzhou Runao Chemical and other companies with corresponding number of functional groups.

[0035] The UV bright paint prepared by embodiment 1-5 and compa...

Abstract

The invention belongs to the technical field of coatings, and in particular relates to a UV bright coating with high wear resistance and high toughness, which consists of the following components in parts by mass: 40-65 parts of polyurethane acrylate resin, 1-10 parts of polyester acrylate resin, Acrylic monomer 1-10 parts, leveling agent 0.1-2 parts, photoinitiator 1-5 parts, mixed solvent 15-30 parts. The present invention uses urethane acrylate resin and polyester acrylate resin as the main resins. The urethane acrylate resin has good wear resistance, adhesion, flexibility and weather resistance, and the polyester acrylate resin has low viscosity and good flexibility. , Low film shrinkage, good adhesion between coatings, etc., the combination of the two can make the paint film have good adhesion, abrasion resistance, flexibility, weather resistance, etc., suitable for 3C products, through UV curing, energy saving and environmental protection; Trifunctional urethane acrylate can provide flexibility and make the paint film have a good feel, and hexafunctional urethane acrylate is beneficial to improve the strength of the paint film and improve the abrasion resistance of the paint film.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a UV bright coating with high wear resistance and high toughness. Background technique [0002] At present, single-component or double-component paints are widely used in the field of 3C manufacturing. The common processing technology is: plastic raw materials→injection molding→cleaning→spraying→packaging. Various appearance effects can be made on the surface of the material by spraying, covering the defects of the material, playing a certain protective role, increasing the aesthetics and practicability of the product, and improving the user experience for consumers. After the product is sprayed, it needs to be disassembled, packaged, and the whole machine needs to be assembled later. These processes can easily lead to cracking of the paint film and affect the appearance. Therefore, there are extremely high requirements on the wear resistance and toughness of the co...
