Embodiment 1

[0033] Embodiment 1: get film-forming resin 60%, curing agent 4.5%, barium sulfate 12%, kaolin 22%, cellulose acetate butyrate 0.09%, antistatic agent 0.16%, benzoin 0.3%, pigment 0.95%, the above-mentioned formula Weigh the raw materials according to the weight percentage, put them into the high-speed mixer and mix them evenly, mix them for 3 minutes, discharge the materials, put the mixed raw materials into the twin-screw extruder for extrusion, and set the temperature of the three stages of the extruder to 30 degrees respectively , 85 degrees, 80 degrees, the extruded sheet is cooled and crushed and then put into the mill to be ground into powder. The classifier speed of the mill is 23Hz, and the fineness is 80 meshes. Add 2% copper and gold powder to the base powder coating, and stir evenly in a low-speed mixer to obtain the final product, which is the preferred result of the coating of the present invention.

Embodiment 2

[0034] Embodiment 2: get film-forming resin 65%, curing agent 4.5%, barium sulfate 12%, kaolin 22%, cellulose acetate butyrate 0.11%, antistatic agent 0.16%, benzoin 0.3%, pigment 0.95%, preparation method is the same Example 1.

Embodiment 3

[0035] Embodiment 3: get film-forming resin 55%, curing agent 4.5%, barium sulfate 12%, kaolin 22%, cellulose acetate butyrate 0.08%, antistatic agent 0.16%, benzoin 0.3%, pigment 0.95%, preparation method is the same Example 1.

[0036] The sample was obtained by spraying, and the appearance of the coating film was visually inspected, and the following results were obtained:

[0037] Example 1: The texture is similar to the hammer mark pattern left by a hammer hitting an iron plate, with high gloss and rich hue.

[0038] Example 2: The lines are large and flat, almost disappearing.

[0039] Example 3: The lines are very small, almost none.

Abstract

The invention discloses an automobile copper-gold hammer artistic coating and a preparation method thereof, wherein the automobile copper-gold hammer artistic coating comprises 55-65 percent of film-forming resin, 4-5 percent of curing agent, 10-20 percent of barium sulfate, 10-40 percent of kaolin, 0.08-0.11 percent of cellulose acetate butyrate, 0.14-0.17 percent of antistatic agent, 0.2-0.4 percent of benzoin, 0-1 percent of pigment and 2 percent of copper-gold powder. The invention has the characteristics that disadvantages are changed into advantages, the chemical resistance of a coated film is improved and the statute limitation is satisfied, and simultaneously brings a bran-new feeling to the coated film of an automobile.

Description

technical field [0001] The invention relates to the field of chemical coatings, more specifically, relates to copper-gold hammer pattern art coatings for automobiles and a preparation method thereof. Background technique [0002] High gloss, high flatness and high vividness are the mainstream requirements for the appearance of automobiles today. With the diversification of technology and the pursuit of individuality by customers, patterned and artistic appearances will also become a trend. Existing topcoats The variety is relatively single. If other effect pigments can be introduced, it will greatly enrich the appearance of the car body. [0003] Existing coating systems include solvent-based coatings, powder coatings, etc. Compared with solvent-based coatings, the leveling of powder coatings is slightly worse, and with the enhancement of environmental awareness and the release of various environmental regulations, solvents are greatly restricted. The use of type coatings, ...
