Problems solved by technology

One of the ways to improve the metallic feeling is to reduce the thickness of the coating, but if the coating is too thin, it will lead to insufficient shielding, poor wear resistance of the coating, and easy to be scratched
In order to solve the problem of wear resistance, a layer of gold oil is usually electroplated, the process is complicated, the qualified rate of the product is reduced, and the cost is increased

Embodiment 1

[0030] A coating for coating the surface of metal materials, comprising the following components proportioned in parts by weight:

[0031]

[0032] The above-mentioned coating for coating the surface of metal materials is prepared by the following method:

[0033] (1) Grind and disperse 15 parts of butyl acetate, 40 parts of acrylic resin, and 5 parts of polyethylene micropowder in proportion to make the particle size less than 5 μm;

[0034] (2) After step (1) is completed, add 5 parts of cellulose acetate butyrate CAB381 while stirring, and disperse with a disperser;

[0035] (3) After step (2) is completed, add 5 parts of byk 310 leveling agent while stirring, and disperse with a disperser;

[0036] (4) After step (3) is completed, add 10 parts of aluminum-silver paste while stirring, and disperse with a disperser;

[0037] (5) After the step (4) is completed, add the remaining 15 parts of butyl acetate while stirring, and disperse with a disperser to obtain a coating ...

Abstract

The invention discloses a coating for coating surfaces of metal materials. In percentage by weight, the coating for coating surfaces of metal materials comprises 25-35 parts of solvent, 40-50 parts of unsaturated polyether resin, 3-6 parts of leveling agent, 2-7 parts of cohesive directional agent, 10-15 parts of effect pigment and 5-20 parts of polyethylene micro powder. The invention also discloses a preparation method of the coating for coating surfaces of metal materials. Due to addition of the cohesive directional agent, the solvent release property of the coating for coating surfaces of metal materials is strengthened; and a substrate is coated with the coating and the cohesive directional agent prompts the solvent to volatilize rapidly, so that a coating film shrink rapidly, and by means of the rapid and strong shrinking force, the directional arrangement of the effect pigment is realized, the shielding property of the coating is improved, the appearance of the coating film is uniform in color and smooth and the metal texture is improved. As the polyethylene micro powder is added, the wear resistance of the coating is improved and the coating film is scratch-resistant; and the coating surface does not need to be electroplated with gold oil, so that the cost is saved.

Description

technical field [0001] The invention relates to a paint for coating the surface of metal materials and a preparation method thereof. Background technique [0002] Unsaturated polyester resin (UPR) has high hardness, high fullness, good weather resistance, water resistance, oil resistance, high gloss, excellent electrical insulation, light weight and low price. In recent decades, the research on the modification of UPR coatings has been a hot spot of attention, and a series of UPR coatings have been produced, which are widely used in the coating of home appliance shells and furniture, anti-corrosion of metal components, and road markings. The planning of the ship, the antifouling of the ship, the insulation of the electronic equipment and the flame retardancy of the fireproof equipment, etc. [0003] At present, the paint used to coat the surface of metal materials prepared by UPR paint, in the spraying process, from the coating used to coat the surface of metal materials on...
