Problems solved by technology

[0006] The purpose of the present invention is to address the deficiencies in the prior art, to provide a high imitation metal powder coating and its preparation method, by improving the formulation and production process, a high imitation metal powder coating is produced, which can not only compare with the market Add more metal powder pigments to other metal powder coatings on the market, which has a strong metallic feel, and does not gamble or spit powder in the later spraying process, and also has excellent leveling characteristics, which solves the problem of adding pearlescent luster to existing metal powders on the market. Or too much metal powder pigment, too much will cause problems such as gun blockage, powder spit out, poor leveling and weak metal feeling. It is an ideal substitute product for "oil to powder"

Abstract

The invention discloses high imitation metal powder paint and a preparation method thereof. The high imitation metal powder paint is prepared from the following raw materials including a fast ingredient A, a slow ingredient B, a surfactant and metal powder pigment. The invention also provides a preparation method. The fast ingredient A and the slow ingredient B are subjected to burdening, high-speed mixing, fusion extrusion, tabletting, cooling and crushing into flake materials; then, the surfactant is added and mixed to prepare bottom powder; finally, the bottom powder and the metal powder pigment are subjected to bonding treatment. The high imitation metal powder paint prepared by the method has the advantages that the metal pigment quantity capable of being added is greater; the metal feeling is stronger; the gun blocking and powder discharging cannot occur in the later-stage spray coating process; the leveling performance is very good; the high imitation metal powder paint belongsto an ideal oil-to-powder substitutable product.

Description

technical field [0001] The invention belongs to the technical field of powder coating preparation, and in particular relates to a high imitation metal powder coating and a preparation method thereof. Background technique [0002] Due to the large amount of VOC emitted by spraying metal paint and the difficulty of pollution control, many metal electroplating factories have used metal powder instead, and the coating effect is ideal. In recent years, due to the advantages of close to zero VOC emissions, powder coatings have become a rapidly developing field in the paint and coating industry. Under the background of the current national green environmental protection and sustainable development, it has driven its rapid development. Most foreign aluminum alloy wheels are painted with metal flash powder coating, which has a smooth, shiny appearance and good mechanical properties. Most of the metal powder coatings used in China are imported. At present, the bonding method is main...
