Novel technological process of imitating electroplating powder coating

Abstract

The invention discloses a novel technological process of an imitating electroplating powder coating; the technological process comprises the following steps and raw material components by the weight percentages: step 1, slice mixing: slicing high-purity special solid polyester resin and epoxy resin for many times to form fine particles, and mixing the fine particles with a small amount of auxiliary agent at high speed in a specific proportion; step 2, mixing after smelting in a smelting tank, cooling for 25-30 min after tabletting, breaking up by a crusher, then grinding, finally separating bya cyclone separator and a screen, and thus obtaining a transparent resin powder; and step 3, fully mixing and bonding the transparent resin powder with a high-brightness metal powder by a time-sharing, frequency-sharing and constant-temperature bonding technology, and thus obtaining a bottom powder having a metal flashing effect. The novel technological process of the imitating electroplating powder coating can greatly improve the glossiness of the powder coating in use and make the glossiness greater than 100 GU. On the other hand, uneven surface distribution and hole shrinkage conditions ofa coating layer can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a novel imitation electroplating powder coating process flow. Background technique [0002] Powder coating is a new type of solvent-free, 100% solid powder coating, which has the characteristics of solvent-free, pollution-free, recyclable, environmental protection, energy and resource saving, labor intensity reduction and high mechanical strength of the coating film. It has the characteristics of energy saving, no VOC emission, good decoration, and safe use. In recent years, powder coating technology has developed rapidly. Powder coating is used as a decorative material. With the affluence of life, people are no longer limited to a single color requirement for powder coating coating. Bonded powder coatings with a metallic appearance are recognized as high-end products in the field of powder coatings. They are well received by home appliances, furniture and automobiles, a...

Problems solved by technology

Among them, the coating of the imitation electroplating powder coating process has excellent mirror effect and beautiful appearance, and is highly sought after by people; the existing imitation electroplating powder coating process has certain disadvantages in the process of use. First, in When in use, the gloss of the coating is dark, the gloss is less than 100GU, and there are unevenly distributed dark spots and shrinkage cavities on the coating. Therefore, we need a new imitation electroplating powder coating process
