Embodiment 1

[0017] A kind of imitation red copper anticorrosion powder coating, by weight, the raw material is composed of: 40 parts of epoxy resin, 44 parts of carboxyl-terminated saturated polyester resin, 1 part of leveling agent, 13 parts of precipitated barium sulfate, 0.5 part of benzoin, 1.5 parts of polyethylene wax.

[0018] Put each component into a high-speed mixer in order to mix evenly, and then extrude through a twin-screw extruder, tablet, cool, crush, and sieve to make a powder coating base powder, and then mix 92 parts of base powder, 4 parts of pearl powder, and 4 A portion of red gold powder was put into a bonding machine, passed through a protective gas, and bonded at 65° C. at 600 rpm for 4 minutes to obtain a bonding powder.

Embodiment 2

[0020] A kind of imitation red copper anticorrosion powder coating, by weight, the raw material is composed of: 44.4 parts of epoxy resin, 43 parts of carboxyl-terminated saturated polyester resin, 1.2 parts of leveling agent, 10 parts of precipitated barium sulfate, 0.6 part of benzoin, 1.8 parts of polyethylene wax, 5 parts of nickel slag powder;

[0021] A method for preparing the above-mentioned imitation red copper anti-corrosion powder coating, each component is put into a high-speed mixer in turn to mix uniformly, and then extruded through a twin-screw extruder, pressed into tablets, cooled, crushed, and sieved to make a powder coating Base powder, then put 92 parts of base powder, 5 parts of pearl powder, 3 parts of red gold powder, and 5 parts of nickel slag powder into the bonding machine, pass in protective gas, and bond at 70°C and 500rpm for 3min to obtain bonding powder.

Embodiment 3

[0023] A kind of imitation red copper anticorrosion powder coating, by weight, the raw material is composed of: 40 parts of epoxy resin, 37.1 parts of carboxyl-terminated saturated polyester resin, 1.1 parts of leveling agent, 19 parts of precipitated barium sulfate, 0.8 part of benzoin, 2 parts of polyethylene wax, 6 parts of nickel slag powder;

[0024] A method for preparing the above-mentioned imitation red copper anti-corrosion powder coating, each component is put into a high-speed mixer in turn to mix uniformly, and then extruded through a twin-screw extruder, pressed into tablets, cooled, crushed, and sieved to make a powder coating For base powder, put 91 parts of base powder, 5 parts of pearl powder, 4 parts of red gold powder, and 6 parts of nickel slag powder into the bonding machine, pass in protective gas, and bond at 60°C and 900 rpm for 6 minutes to obtain bonding powder.

Abstract

The invention belongs to the field of powder coating preparation, and particularly relates to a pure-copper-imitated anti-corrosion powder coating. The pure-copper-imitated anti-corrosion powder coating is composed of, by weight, 35-40 parts of epoxy resin, 35-40 parts of terminal carboxyl group saturated polyester resin, 1-1.2 parts of flatting agents, 10-19 parts of precipitated barium sulphate, 4-5 parts of pearl powder, 3-4 parts of red gold powder, 0.5-0.8 part of benzoin, 1.5-2 parts of polyethylene wax and 5-6 parts of nickel slag powder. According to the pure-copper-imitated anti-corrosion powder coating, the pearl powder and the red gold powder are bound to be added, metallic pigment particles are bonded on powder coating particles to prepare a coating layer with the metal effect, and therefore the problem that the powder coating is difficult to achieve the paint effect can be well solved; nickel slag is added in the powder and is rich in amphoteric oxide of Al2O3 and Fe2O3, the amphoteric oxide can react with acid and alkali, and therefore the good acid and alkali resistance effects can be well achieved.

Description

technical field [0001] The invention belongs to the field of preparation of powder coatings, in particular to a copper imitation anticorrosion powder coating. Background technique [0002] Powder coatings are different from solvent-based coatings such as paints. After the dry powder is sprayed, baked, melted, leveled and solidified, metal substances are mixed in it. It is difficult to achieve the metallic effect of the paint, and only the color can be close. The colors of metal powder are mainly silvery white, champagne, red copper and brass. At present, there are few powder coatings with imitation red copper color on the market. And even if copper powder is added to the powder coating, it is difficult to achieve the metallic effect of imitating copper in the paint. Contents of the invention [0003] The object of the present invention is to provide a kind of anticorrosion powder coating imitating red copper aiming at the deficiencies of the prior art. By improving the ...
