Abstract

The invention discloses an ultraviolet-curable anti-fingerprint antistatic paint composition comprising the components of, by weight: 5-10 parts of fluorine-modified acrylate oligomer, 10-20 parts of silicon-modified acrylate oligomer, 50-65 parts of high-functionality acrylate oligomer, 10-20 parts of high-functionality acrylate monomer, 5-10 parts of dual-functionality monomer, 4-6 parts of a photoinitiator, 2-5 parts of an antistatic auxiliary agent, and 0.05-3 parts of an auxiliary agent. According to the invention, UV-curable anti-fingerprint resin and UV-curable antistatic auxiliary agents are adopted. The composition can be directly used in an existing UV-hardened paint system. After UV curing, anti-fingerprint performance and antistatic performance achieve good synergetic effect. The coating has dual effects of preventing fingerprint and preventing static electricity. No auxiliary agent migration surface exists. Anti-fingerprint and antistatic effects are not influenced.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an ultraviolet curing anti-fingerprint and antistatic coating composition. Background technique [0002] Ultraviolet curing coatings (UV coatings) are developing rapidly. Because the cured coatings have the advantages of excellent scratch resistance, high hardness, and good fullness, and because of their advantages in high efficiency, energy saving, environmental protection, and economy, they are widely used in construction, It is widely used in sporting goods, electronic communication, packaging materials and auto parts. Due to the high light transmittance and low density of acrylic (PMMA, commonly known as plexiglass) or acrylic / polycarbonate (PMMA / PC) composite sheets, which are easy to process and shape, they are more and more used in the optical field, such as camera lenses. , touch screen, instrument panel protective cover, etc. The currently used PMMA sheet or PMMA / PC composite s...
