Abstract
The invention provides a UV curing high wear-resistant low luster coating and a preparation method thereof. The coating comprises the following components in percentage by weight: primer and a curingagent, wherein, the primer comprises 55-60 of hydroxyl acrylic resins, 10-13 of solution containing 20% of cellulose acetate butyrate resins, 4-6 of methyl isobutyl ketone, 0.1-0.2 of flow agent, 5-7of aluminum paste and 17-19 of ethyl acetate; the curing agent comprises 55-60 of hexamethylene diisocyanate, 10-15 of unsaturated aliphatic polyurethane acrylate and 26-32 of butyl acetate. The invention has the advantages as follows: the invention has low VOC discharge when being used for construction under common coating conditions; the invention can achieve the effects of high wear resistanceand difficult surface shining by using the common plastics coating method; the invention features simplicity and commonality of construction and has very good adhesion on the plastics and aluminum; the invention features thin film thickness and has cost lower than that of the common UV coatings.
Description
technical field [0001] The invention relates to an ultraviolet light-cured high-wear-resistant matte coating and a preparation method thereof. The coating is suitable for plastic keyboards, such as ABS+PC keycaps or aluminum keyboards. Background technique [0002] With the popularization of computers, the keyboard has become the most contacted product in our daily life and work, but the current keyboard is mainly plastic or a small amount of conventional matte UV-cured coating, due to the plastic itself and ordinary UV light The defects in the design of the cured coating itself lead to its non-scratch resistance, non-abrasion resistance, surface shine or coating loss after long-term use, which affects the appearance of the keyboard and reduces its protection. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a UV-cured high wear-resistant matte coating, which has the characteristics of thinner co...
