Abstract

The invention discloses an aluminum pigment for plastic paint. The aluminum pigment is characterized by consisting of the following raw materials in parts by weight: 40-60 parts of micron-scale spherical aluminum powder, 0.1-0.2 part of polyglycerol ricinoleate, 1-2 parts of n-butyl acetate, 20-30 parts of 200# solvent oil, 1-2 parts of talc powder, 0.3-0.5 part of silane coupling agent A-151, 1-2 parts of tributyl acetyl citrate, 8-12 parts of ethyl orthosilicate, 0.5-1 part of zinc stearate, 4-6 parts of polytetrafluoroethylene micro powder, 0.2-0.4 part of glycerol monolaurate, 0.5-1 part of silane coupling agent KH-550, 8-10 parts of ethyl acetate, 0.5-1 part of propylene glycol and 2-4 parts of aids. The aluminum pigment disclosed by the invention has good adhesive force on the surface of a plastic substrate, is convenient to coat, long-acting and fouling resistant, has good mechanical property and self-cleaning effect, can effectively solve the problems that the plastics are easy to age, scratch and stain and is suitable for the plastic paint.

Description

technical field

[0001] The invention relates to the field of metal pigments, in particular to an aluminum pigment for plastic paint and a preparation method thereof. Background technique

[0002] Plastic has the characteristics of light weight, easy processing, corrosion resistance, rich resources, etc., and is widely used. However, when plastic products are molded and processed, defects such as uneven color, monotonous color, and mottled defects will occur, and problems such as aging and brittleness, scratches, and stains will easily occur. Applying plastic paint can avoid the above-mentioned defects and problems. Metallic pigments are pigments made by grinding metal or alloy particles or flakes. They have metallic luster, can give the product a metallic appearance, and form a smooth thin-layer coating film. They have unique decorative and hiding power and are widely used. in the paint industry. Due to the chemical characteristics of metal pigments, their stability in th...
