Abstract

The invention discloses a gray masterbatch, comprising the following components in parts by weight: 76.64-78.68 parts of carrier resin, 0.8-1.2 parts of dispersant, 19.7-21.1 parts of titanium dioxide, 0.62-0.66 parts of nickel-titanium yellow, and carbon black 0.10-0.20 part, 0.10-0.20 part of phthalocyanine green. The gray masterbatch prepared by the invention is safe and environmentally friendly, and the color of the product prepared by adding the gray masterbatch to the plastic is completely consistent with the color of the target sample under different light source conditions, which effectively solves the problem between the product and the target sample. The problem of metamerism is that 99% by weight of the color-developing substance in the present invention adopts inorganic toner. Compared with organic toner, inorganic toner has higher light resistance, weather resistance and corrosion resistance. Internal advantages are obvious.

Description

technical field [0001] The invention relates to the technical field of plastic processing and color matching, in particular to a gray masterbatch and a preparation process thereof. Background technique [0002] Cars will encounter different lighting environments during use. Therefore, in the process of making plastic parts for cars, it is necessary to ensure that the color of the product is consistent with the color of the standard sample under different lighting conditions. The automotive industry internally stipulates three types Common light sources, namely D65, A and F11, the overall color matching level in the existing plastic dyeing industry is insufficient, and it is basically impossible to ensure color uniformity under different light sources, resulting in the result that the color of the product is inconsistent with the color of the standard sample under different light sources. problem, the phenomenon of metamerism. For example, if the overall color is under natur...
