Problems solved by technology

Compared with inorganic pigments, the existing paint formulations and techniques containing red powder have disadvantages such as low light fastness, poor weather resistance, poor hiding power and high cost, which are difficult to meet the application requirements.
The organic pigment industry has been reducing costs by adding inorganic fillers through simple mixing methods, but this method can no longer meet the requirements of improving the light resistance, heat resistance and weather resistance of organic pigments

Embodiment 1

[0012] The formula contains the following components according to the weight ratio: 30 parts of bisphenol A epoxy resin, 30 parts of saturated polyester resin, 25 parts of precipitated barium sulfate, 1 part of leveling defoamer, 0.5 parts of stearic acid, 7 parts of titanium dioxide, 0.5 parts of carbon black, 3 parts of red powder.

[0013] The process is to mix the components, then melt, extrude and cold-press them into flakes, then crush the flakes and grind them into powder, sieve the powder and mix it with aluminum powder with a particle size of 30-50 mm to make Finished glitter powder coating.

[0014] The weight proportion of aluminum powder is 3 parts.

Embodiment 2

[0016] The formula contains the following components according to the weight ratio: 28 parts of bisphenol A epoxy resin, 30 parts of saturated polyester resin, 25 parts of precipitated barium sulfate, 1 part of leveling defoamer, 0.5 parts of stearic acid, 8 parts of titanium dioxide, 0.5 parts of carbon black, 4 parts of red powder.

[0017] The process is to mix the components, then melt, extrude and cold-press them into flakes, then crush the flakes and grind them into powder, sieve the powder and mix it with aluminum powder with a particle size of 30-50 mm to make Finished glitter powder coating.

[0018] The weight proportion of aluminum powder is 3 parts.

Embodiment 3

[0020] The formula contains the following components in proportion by weight: 28 parts of bisphenol A epoxy resin, 28 parts of saturated polyester resin, 28 parts of precipitated barium sulfate, 1 part of leveling defoamer, 0.5 parts of stearic acid, 7 parts of titanium dioxide, 0.5 parts of carbon black, 4 parts of red powder.

[0021] The process is to mix the components, then melt, extrude and cold-press them into flakes, then crush the flakes and grind them into powder, sieve the powder and mix it with aluminum powder with a particle size of 30-50 mm to make Finished glitter powder coating.

[0022] The weight proportion of aluminum powder is 3 parts.

Abstract

The invention discloses a flashing powder coating containing a pigment scarlet. The flashing powder coating is characterized by comprising the following components in parts by weight: 28-30 parts of bisphenol-A epoxy resin, 28-30 parts of saturated polyester resin, 25-28 parts of precipitated barium sulphate, 1-1.2 parts of a leveling defoamer, 0.5-1 part of stearic acid, 7-9 parts of titanium dioxide, 0.5-1 part of carbon black and 3-4 parts of pigment scarlet; and the flashing powder coating is prepared through mixing various components, carrying out melting, extruding and cold pressing to form sheets, crushing and grinding the sheets into powder, sieving the powder and then mixing with aluminite powder of which the particle sizes are 30-50mm. The flashing powder coating prepared by adopting the formula and the process has the characteristic of being stable and persistent in flashing effect.

Description

technical field [0001] The invention belongs to the technical field of metallic coatings, and specifically discloses a flashing coating containing red powder. Background technique [0002] Azo organic pigment red powder is widely used in the coloring function of coatings, inks, paints, leather, rubber, plastics, latex products, building materials and cosmetics. Compared with inorganic pigments, the existing paint formulations and techniques containing red powder have disadvantages such as low light fastness, poor weather resistance, poor hiding power and high cost, which are difficult to meet the use requirements. The organic pigment industry has been reducing costs by adding inorganic fillers through simple mixing methods, but this method can no longer meet the requirements of improving the light resistance, heat resistance and weather resistance of organic pigments. How to adopt the best ratio and technology to improve the heat resistance and water dispersibility of the p...
