Aluminum silver powder powdery paint and preparation method

Abstract

The invention discloses an aluminum silver powder powdery paint and a preparation method. The powdery paint mainly comprises, by weight, 25 to 35% of E-12 epoxy resin, 25 to 35% of polyester resin, 21 to 41% of precipitated barium sulfate and titanium dioxide, 1 to 3% of aluminum silver powder, 1 to 1.2% of a levelling agent, 1.2 to 1.5% of a sensitizer, 0.2 to 0.8% of wax powder, 0.5 to 0.6% of benzoin and 0.5 to 1% of an anti-oxidant. The aluminum silver powder powdery paint can improve levelability and enhance the performance of wear resistance and scratch resistance, and has good performance of environmental protection. The invention also discloses a preparation method for the aluminum silver powder powdery paint. Metal pigments prepared by the method can bond to the surface of resin powder of a substrate, thereby enabling the produced products to have high strength in resisting impacts, corrosion resistance and strong ability in adapting to environment and enabling curing time to be short and cost to be saved.

Description

technical field [0001] The invention relates to a coating, in particular to a powder coating, which belongs to the technical field of chemical coatings. Background technique [0002] As a new type of coating with high performance, low pollution, less pollution and energy saving, powder coating has become one of the important products to replace traditional solvent-based coatings. Among the many branches of powder coatings, aluminum silver powder coatings have become the mainstream direction of the development of modern coatings industry due to their extremely low content of volatile organic compounds and energy saving. [0003] The main components of aluminum-silver powder coatings are metal pigments and resin powders. Existing aluminum-silver powder coatings have the following defects: the separation of metal pigments and resin powders occurs during use; There will be a certain difference in the content of the material, resulting in inconsistent appearance of the material ...

[0003] The main components of aluminum-silver powder coatings are metal pigments and resin powders. Existing aluminum-silver powder coatings have the following defects: the separation of metal pigments and resin powders occurs during use; There will be a certain difference in the content of the material, resulting in inconsistent appearance of the material and color cast phenomenon; metallic pigments are easy to accumulate, and when spraying with an electrostatic gun, it is easy to block the muzzle; the selection range of metallic pigments is narrow, and a variety of colors cannot be blended; metallic pigments The low chargeability makes the powder coating rate of powder coating low
