Abstract

The invention discloses a high gloss high abrasion resistance ultra-violet (UV) curing overprinting varnish of mobile phone and a preparation method thereof. The method of the invention uses low-viscosity polyester acrylate and aliphatic polyurethane acrylate as base resin which combines with ethoxylated pentaerythritol tetraacrylate, Trimethylolpropane triacrylate, Tri(propylene glycol) diacrylate, 1,6-hexanediol diacrylate and 2-ethylhexyl acrylate which are used as active diluent, alcohol and ethyl acetate which are used as diluent, benzophenone and 1-hydroxycyclohexyl phenyl ketone which are used as photoinitiator, reactive amine coinitiator, defoaming agent, flatting agent, slip agent and other agents to mix evenly and prepare the UV overprinting varnish. The overprinting varnish of the invention adopts the special raw material formula and has good lustrousness, adhesive force and mechanical stability; as some polyfunctional resins and resins with special functional groups are added, the crosslink density of the UV varnish is increased in the curing process and the hardness of the product is up to 5-7H; and as solid wax powder used as the slip agent is added, the coefficients of friction can be reduced and the product can have extremely high wear resistance.

Description

technical field [0001] The invention relates to the field of varnishes, in particular to a layer of UV varnishes used on mobile phone casings. Background technique [0002] At present, there are many varieties of mobile phone UV varnishes on the market. Since most of the raw materials are imported products, the price of the products produced is too high, and the final domestic performance still cannot meet the requirements of customers. Therefore, low-cost high-performance mobile phones are developed. UV varnish has a broad market prospect. Contents of the invention [0003] The present invention is just to overcome the above-mentioned deficiencies, and the technical problem to be solved is to provide a high-gloss and high-wear-resistant mobile phone UV varnish with low price and excellent performance. [0004] The technical problem that the present invention also needs to solve is to provide the manufacture method of above-mentioned mobile phone UV varnish. [0005] In ...
