Environment-friendly high-reflectivity powder coating for lamp cavity .and preparation method thereof

Abstract

The invention discloses an environment-friendly high-reflectivity powder coating for a lamp cavity and a preparation method thereof. The environment-friendly high-reflectivity powder coating comprisesthe following components in parts by weight: 25-30 parts of epoxy resin, 25-30 parts of polyester resin, 1-2 parts of a leveling agent, 0.5-1 part of a defoaming agent, 20-25 parts of titanium dioxide, 10-15 parts of precipitated barium sulfate, 3-5 parts of a light-reflective material and 0.05-0.1 part of a pigment. The preparation method of the environment-friendly high-reflectivity powder coating for the lamp cavity comprises the following steps: mixing formula materials, melting, extruding, tabletting, roughly crushing until the crushed grain diameter to a median diameter of 26um+ / -1um, and packaging into a finished product, the finished product is suitable for the lamp cavity, conforms to ROHS instructions and REACH regulations, can manufacture high-gloss and sub-gloss high-reflectivity coatings, and has stable coating and simple production process.

[0001] 【Technical field】

[0002] The invention relates to the technical field of powder coatings, in particular to the technical field of an environment-friendly high-reflectance powder coating for a cavity of a lamp and a preparation method thereof.

[0003] 【Background technique】

[0004] In the past, the surface protection and decoration of the lighting industry usually used electroplating, which has beautiful, diverse, decorative and anti-corrosion properties. However, the material selection requirements of the electroplating solution are relatively high, the cost is high, and the pollution of electroplating is relatively large. In addition, with the rapid development of the decoration industry and supporting products driven by the construction industry and real estate development, consumers are increasingly emphasizing and pursuing unique lamps and lanterns with different styles in public and home decoration, and pay more attention to the overall color tone. harmony.
