Abstract

The invention relates to a light solidifying high-abrasion resistant fingerprint resistant coating which is used for the surfaces of plastic shells of portable electronic products, such as mobile phones, MP3, digital cameras, handheld computers, and the like and comprises the following components: 10-35 percent of high-functionality urethane acrylate, 5-25 percent of bifunctional urethane acrylate, 0.01-20 percent of acrylic ester monomer, 5-20 percent of high-functionality acrylic ester, 5-40 percent of fluorin-contained acrylic ester, 0.01-10 percent of nano inorganic powder filler, 1-5 percent of light initiating agent, 0.01-5 percent of auxiliary agent and 5-30 percent of solvent. The invention improves the fingerprint resistant capability of a coating film by the enrichment and microphase separation of a fluorin-contained group added into the coating on the surface of a coating surface, provides excellent abrasion resistance and hardness by using the polyurethane structure in the coating and the added nano abrasion resistant filler and meets the requirements of abrasion resistance, scratch resistance and fingerprint resistance of the portable electronic products.

Description

technical field [0001] The invention relates to a light-cured high wear-resistant and anti-fingerprint paint used on the surface of plastic shells of portable electronic products such as mobile phones, MP3 players, digital cameras, and laptop computers. technical background [0002] UV curing coating is a coating that can undergo physical and chemical changes in a short period of time after being irradiated by ultraviolet light. Compared with traditional natural drying or heat-curing coatings, UV-curing coatings not only have fast curing speed, energy saving, excellent coating performance, wide application range for substrates, and less volatile solvent consumption, but also have a significant Features: The curing process does not require heating, which is very useful for some plastic, optical and electronic parts that cannot withstand heat, so it is very suitable for the protection and decoration of the plastic shell surface of mobile phones, computers and other electronic ...
