Problems solved by technology

[0003] Although general UV varnish has the characteristics of high gloss and high hardness, it has the following defects: it is easily stained by fingerprints, the imprint of oil-based pens is not easy to remove, and its pollution resistance is poor; thus, it is limited to a certain extent. its application
In China, the research on anti-fingerprint UV varnish used on PC / ABS plastic parts has not been reported yet.

Abstract

The invention discloses fingerprint resisting UV light oil which mainly comprises the following components according to the weight portion: 30-35 of stain resisting low polymer, 5-6 of urethane acrylate, 15-18 of polymer modified acrylate, 15-18 of tri(propylene glycol) diacrylate, 25-30 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 120-140 of diluting agent. The invention develops the fingerprint UV light oil which has fingerprint resisting effect, easy cleaning of permanent pen marks and better oil stain resistance and is used for an ABS+PC plastic piece 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 UV light oil 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 UV coatings, in particular to an anti-fingerprint UV varnish used on engineering plastic parts and an operating method thereof. Background technique [0002] At present, UV coatings are the most widely used in high-efficiency protective and decorative coatings, mainly used in different fields such as wood floors, wooden furniture, plastic floors, electronic components, PC (polycarbonate) lampshades, packaging materials, etc. ; Moreover, as people pay more and more attention to environmental protection, the application of UV coatings will become more and more extensive. [0003] Although general UV varnish has the characteristics of high gloss and high hardness, it has the following defects: it is easily stained by fingerprints, the imprint of oil-based pens is not easy to remove, and its pollution resistance is poor; thus, it is limited to a certain extent. its application. [0004] Anti-fingerprint UV varnish not only has th...
