Problems solved by technology

[0003] Although general UV-curable coatings have the characteristics of high gloss and high hardness, they also have the following defects: easy to be stained by fingerprints, imprints of oil-based pens are not easy to remove, and poor pollution resistance
In China, the research on anti-fingerprint UV-curable coatings used on PC plastic parts has not yet been reported.

Abstract

The invention discloses a fingerprint resisting ultraviolet curing paint which mainly comprises the following components according to the mass percent: 25-28 of stain resisting low polymer, 4-6 of multifunctional-group aliphatic urethane acrylate, 5-6 of urethane acrylate, 22-25 of polymer modified acrylate, 25-30 of tri(propylene glycol) diacrylate, 15-18 trimethylolpropane methylacrylate, 4-5 of 1-hydroxycyclohexy phenyl ketone, 0.4-0.5 of stain resisting photo-curing assistant, 0.1-0.3 of flatting agent and 120-130 of diluting agent. The invention develops the fingerprint ultraviolet curing paint which has fingerprint resisting effect, easy cleaning of permanent pen marks and better oil stain resistance and is used for a PC board by adopting stain resisting low polymer as main resin and adding the stain resisting photo-curing assistant in the formulation, and solves the problems that common ultraviolet curing paint is easily stained by fingerprints, the permanent pen marks are not easy to remove and the stain resistance is poor.

Description

technical field [0001] The invention relates to curing technical coatings, in particular to an anti-fingerprint ultraviolet curing coating used on PC boards and an operation method thereof. Background technique [0002] In recent years, with the rapid development of modern science and technology, UV-curable coatings (UVCC), as a new type of curing technology coating, have shown a good momentum of rapid development with each passing day. Because of its fast curing speed (0.1 to 10 seconds to complete curing), energy saving (energy consumption is about 1 / 5 to 1 / 10 of thermal curing coatings) and excellent coating performance (such as high gloss, high hardness, etc.) , Good chemical resistance, etc.) and other advantages, it is widely used in different fields such as building materials, sporting goods, electronic communications, packaging materials and auto parts. [0003] Although general UV-curable coatings have the characteristics of high gloss and high hardness, they also ...
