Problems solved by technology

[0003] However, in the application of the speckle powder coating, it is found that the speckle coating film still has obvious smearing and fading phenomenon, which is caused by the inherent insufficient wetting of the texture pigment and the base resin, and even the products produced by the hot mixing process cannot be eliminated.

Embodiment 1

[0019] An artistic powder coating with a stripe effect, which is prepared by mixing A powder, B powder and pearl powder at a weight ratio of 90:5:5;

[0020] Described A powder is made up of following raw material: epoxy resin 40wt%, carboxyl-terminated polyester resin 40wt%, precipitated barium sulfate 5wt%, cellulose acetate butyrate 0.2wt%, titanium dioxide 14wt%, carbon black 0.8wt%;

[0021] The B powder is composed of the following raw materials: 90wt% hydroxyl-terminated polyester resin, 5wt% pigment, and 5wt% polyether polymer.

[0022] The polyether polymer is polyoxypropylene glycol.

[0023] A method for preparing the art type powder coating of the above-mentioned speckle effect, comprising the following steps:

[0024] 1) Mixing epoxy resin, carboxyl-terminated polyester resin, precipitated barium sulfate, cellulose acetate butyrate, titanium dioxide and carbon black, extruding, tablet crushing, grinding and sieving to obtain powder A;

[0025] 2) Mixing, extrudi...

Abstract

The invention belongs to the field of powder coating preparation and particularly relates to an artistic powder coating with the stripe effect and a preparation method thereof. The coating is obtained by mixing power A, powder B and pearl powder according to the weight ratio of 90: 5: 5; the powder A is composed of, by weight, 40% of epoxy resin, 40% of carboxyl-terminated polyester resin, 5% of precipitated barium sulphate, 0.2% of cellulose acetate butyrate, 14% of titanium dioxide and 8% of carbon black; the powder B is composed of, by weight, 90% of hydroxyl-terminated polyester resin, 5% of pigment and 5% of polyester polymer. The obtained coating is good in weatherability, adhesion is obviously improved, the phenomenon that pigment particles fall in the coating wiping process is obviously reduced, and product quality is comprehensively improved.

Description

technical field [0001] The invention belongs to the field of powder coating preparation, and in particular relates to an art-type powder coating with a stripe effect and a preparation method thereof. Background technique [0002] Artistic powder coatings are one of the important varieties of powder coatings. At present, artistic powder coatings mainly include sand wrinkle, orange grain, hammer grain, embossing, flash, metallic color, etc. Among them, the pattern powder coating is based on the optimal appearance and visual sense. , outstanding concave-convex touch, excellent physical and mechanical properties and good covering effect are constantly gaining people's favor. [0003] However, in the application of the speckle powder coating, it is found that the speckle coating film still has obvious smearing and fading phenomenon, which is caused by the inherent insufficient wetting of the texture pigment and the base resin, even if the product is produced by the hot mixing pro...
