Problems solved by technology

[0002] At present, most of the coatings with cracked appearance are sprayed by liquid solvent-based coatings, less prepared by environmentally friendly solid powder coatings, and mainly cracks on the silver surface, and cracks in other colors must first be extruded separately. Mix and spray with flour in an appropriate proportion, the resulting cracked coating has low surface gloss, poor fullness, and unstable cracked appearance

Embodiment 1

[0012] Weigh the following raw materials respectively: 40 kg of epoxy resin with an epoxy value of 0.11 to 0.13 mol / 100 g, 42 kg of polyester resin with an acid value of 50 to 75 mgKOH / g, 2 kg of stearic acid, and 0.5 kg of benzoin. 5 kg of color organic pigments, 0.3 kg of butyl acrylate and methacrylic acid copolymer with a fineness of 80-160 mesh, and 10 kg of complexion inorganic pigments.

[0013] Weigh epoxy resin, polyester resin, stearic acid, and base color pigments in proportion to prepare a pre-dispersed mixture, and then mix at high speed, melt extrusion, tablet pressing, crushing, and pass through a 140-160-mesh sieve. Make base powder, add butyl acrylate and methacrylic acid copolymer with a fineness of 80-160 mesh according to the proportion of the formula, mix evenly, and pass through a 100-160 mesh sieve to make a finished product.

Embodiment 2

[0015] Weigh the following raw materials respectively: 45 kg of epoxy resin with an epoxy value of 0.11 to 0.13 mol / 100 g, 44 kg of polyester resin with an acid value of 50 to 75 mgKOH / g, 5 kg of hydrogenated castor oil, and 0.3 kg of benzoin. 15 kg of color inorganic pigments, 0.3 kg of powdered acrylic homopolymer, and 5 kg of complexion inorganic pigments.

[0016] Weigh epoxy resin, polyester resin, hydrogenated castor oil, and base color pigments in proportion to prepare a pre-dispersed mixture, then mix at high speed, melt extrusion, tablet pressing, crushing, and pass through a 140-160 mesh sieve. Make a base powder, then add powdered acrylic homopolymer and face paint according to the formula ratio, mix evenly, and pass through a 100-160 mesh sieve to make a finished product.

Abstract

The invention discloses an epoxy / polyester typed crack powder paint, which comprises the following parts: 40-45% epoxide resin, 40-45% polyester resin, 0.5-5% flow accelerant, 0.1-0.5% benzoin, 1-20% fundamental color dye, 0.1-0.5% emulsion and 1-15% face color dye. the invention also provides a making method, which possesses high coating surface gloss and stable effect.

Description

technical field [0001] The invention relates to a coating, in particular to a coating which can be made into a cracked appearance coating. Background technique [0002] At present, most of the coatings with cracked appearance are sprayed by liquid solvent-based coatings, less prepared by environmentally friendly solid powder coatings, and mainly cracks on the silver surface, and cracks in other colors must first be extruded separately. Mix and spray with flour in an appropriate proportion, the surface gloss of the obtained cracked coating is low, the fullness is poor, and the appearance of cracks is unstable. Contents of the invention [0003] The purpose of the present invention is to provide an epoxy / polyester type cracked powder coating with high surface gloss, good plumpness and stable appearance cracking effect of the obtained cracked coating. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] An epoxy / polye...
