Abstract

The invention discloses a high-imitation anodic treatment powder paint, which comprises the following raw materials by weight: 900-1000 parts of epoxy resin, 900-1000 parts of polyester resin, 20-25 parts of mica powder and 1-3 parts of an arrangement agent. The high-imitation anodic treatment powder paint disclosed by the invention can greatly improve the surface leveling properties and glossiness of a film formed by the powder paint, the leveling properties of the obtained paint film can reach level 10, and the glossiness can reach 600 degrees or above, the surface of the paint film has metal luster, and after the paint is coated on a device surface, a good anode-imitation effect can be achieved, so that the high-imitation anodic treatment powder paint provided by the invention can replace traditional high-pollution anode electroplating and be used for preparation of device surface coatings. The invention also discloses a preparation method and application of the high-imitation anodic treatment powder paint, the method adopts special multi-stage control speed stirring processing, has the characteristics of precise temperature control, convenient operation, low cost, and environment-friendly and pollution-free preparation process.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a high imitation anodized powder coating and its preparation method and application. Background technique [0002] Most of the high imitation anodized powder coatings currently use epoxy resin and polyester formulations, which are directly formed after stirring. The gloss of the product obtained by this method is relatively low, which can only reach about 200 degrees, and it is not suitable for outdoor requirements. Therefore, there is an urgent need for a powder coating with high surface gloss and adaptability to outdoor conditions, and to develop an outdoor high imitation anodized powder coating preparation process with easy control of the preparation process and high gloss without pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies and defects mentioned in the above background technology, provide a...
