preparation example Construction

[0066] Diamond colorful UV coating of the present invention is made by above-mentioned composition, and preparation method comprises as follows:

[0067] Mix 20-40 parts by weight of film-forming substances, 3-15 parts by weight of pigments, 5-10 parts by weight of functional materials, and 5-15 parts by weight of coating additives, and disperse uniformly at high speed, and mix 2-5 parts by weight of initiator with solvent until dissolved , and then added to the mixture of film-forming substances and the like, stirred and dispersed uniformly to obtain the diamond multicolored UV coating.

[0068] Therefore, contain the component of following weight portion in the multicolored UV coating of diamond of the present invention:

[0069] 20-40 parts by weight of film-forming substances;

[0070] Pigment 3~15 parts by weight;

[0071] 5-10 parts by weight of functional materials;

[0072] 5-10 parts by weight of coating additives;

[0073] Initiator 2~5 parts by weight;

[0074]...

Embodiment 1

[0096] Preparation of Diamond Colorful UV Coatings

[0097] Prepare raw material according to the weight part in following table 2, adopt following steps to make coating:

[0098] First, put the UV resin and monomer into the dispersion tank, control the speed at 500 rpm, and disperse for 5 minutes until uniform; slowly add the functional material, wetting agent, and defoamer into the dispersion tank at 900 rpm, and disperse at a high speed 20 minutes; dissolve the initiator in part of the solvent first, disperse at 600 rpm until clear and transparent, and then add it to the dispersion tank; wet and soak the aluminum powder with solvent weight 1:1 for 1 hour, and stir at 400 rpm for 10 minutes Add it to the dispersion tank until it is uniform; add other toning pigments and disperse for 20 minutes; finally adjust the viscosity with a solvent for 15 seconds (NK-2# viscosity cup), and then the finished product is made.

Abstract

The invention relates to a high-hardness super wear-resistant and fouling-resistant diamond colorful UV coating. Specifically, the coating disclosed by the invention is prepared from 20 to 40 weight parts of a film forming substance, 3 to 15 weight parts of a pigment, 5 to 10 weight parts of a functional material, 5 to 15 weight parts of a coating additive, 2 to 5 weight parts of an initiator anda diluent, wherein the film forming substance is 6-15-polyfunctional group aliphatic acrylic polyurethane and 4-6 functional group aliphatic monomer, and the functional material is a nano-scale hardening wear-resistant material. The UV coating prepared from the composition of the invention has 8-9 H pencil hardness, 100 times of tests on the coating with a tungsten resisting needle show that the coating is non-discoloring, and the high-hardness super wear-resistant and fouling-resistant diamond colorful UV coating is resistant to fouling and fingerprints, can be made into various colors and appearances, can be sprayed at one time, and can be widely applied to 3C products and medical equipment.

Description

technical field [0001] The invention relates to a UV paint, in particular to a high-hardness, super-abrasion-resistant and pollution-resistant colorful UV paint, which can be widely used in the decoration and protection of high-end and high-end expensive equipment. Background technique [0002] In recent years, high-end 3C devices such as mobile phones and computers have higher and higher requirements for paint films, such as the hardness of paint films, scratch resistance, fingerprint resistance, pollution resistance, and appearance diversity. At the same time, in terms of coating construction simplification and cost control, it is faced with the need to continuously reduce and enhance competitiveness. [0003] The disadvantages of traditional coatings are: [0004] 1. Insufficient hardness, generally between 1-4H; [0005] 2. The scratch resistance is insufficient, and the scratch resistance of tungsten needles is generally within 30 times; [0006] 3. Multiple coats of...
