Embodiment Construction

[0038] The technical solutions of the present invention will be further described below through specific embodiments.

[0039] Unless specifically stated, various raw materials of the present invention can be purchased commercially, or can be prepared according to conventional methods in the art.

[0040] The present invention prepares UV hardening liquid by following preparation method:

[0041] 1) In terms of mass percentage, 1-4% of 1-hydroxy-cyclohexyl phenyl ketone (184) and 0.1-0.8% of 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO) was added into 30-65% methyl isobutyl ketone, stirred and dissolved, and stirred for 10-30 minutes to completely dissolve the initiator to obtain a mixed solution;

[0042] 2) In terms of mass percentage, add 40-80% of the resin grafted with fluorine-containing acrylic compound to the mixed liquid in step 1), and stir for 30-60 minutes to dissolve the resin;

[0043]3) Filter the solution obtained in step 2 with a 0.5-1 μm filter eleme...

Abstract

The invention provides a UV-curable liquid and a preparation method and an application thereof. The UV-curable liquid disclosed by the invention consists of the following substances in percentage by weight: 1 to 4 percent of 1-hydroxy-cyclohexyl phenyl ketone, 0.1 to 0.8 percent of 2,4,6-trimethylbenzoyldiphenyl phosphine oxide, 30 to 65 percent of methyl isobutyl ketone and 40 to 80 percent of fluoroacrylate compound-grafted rein, and the sum of the weight percentage contents of the substances is 100 percent. After the UV-curable liquid disclosed by the invention is cured to form a film, the film has high hardness and good wear resistance and fingerprint-proof property; and the UV-curable liquid can be used as curable liquid for PMMA (polymethylmethacrylate) board, and can be applied in the field of processing shells of electronic products.

Description

technical field [0001] The invention belongs to the technical field of resin coatings, and relates to a UV hardening liquid and its preparation method and application. Background technique [0002] Polymethyl methacrylate (PMMA) sheet, commonly known as plexiglass, is a thermoplastic with excellent light transmittance. It uses methyl methacrylate as the main base material, and adds initiators, plasticizers, etc. made. PMMA has excellent light transmission, can pass through 99% of light, and can pass through 73.5% of ultraviolet rays. It has high mechanical strength, good heat resistance, cold resistance and weather resistance, corrosion resistance and insulation. Good; Dimensionally stable and easy to process under certain conditions. With PMMA board as the base material, many product applications can be derived, such as mobile phone panels, mobile phone cases, etc. Most of the mobile phone casings require wear-resistant hardness and anti-fingerprints, so various UV harde...
