Abstract

The invention discloses a brown masterbatch, which comprises the following components in parts by weight: 26.8-30.4 parts of carrier resin, 0.8-1.2 parts of plastic additive, 9.8-10.2 parts of dispersant, 6.0-6.4 parts of titanium dioxide, and red iron oxide 8.8-9.2 parts, bismuth vanadate yellow 5.8-6.2 parts, titanium yellow 35.9-37.1 parts, carbon black 2.5-2.9 parts. The brown masterbatch prepared by the present invention is safe and environmentally friendly. The color of the product obtained by adding the brown 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. For the problem of metamerism, 99% by weight of the chromogenic substance in the present invention adopts inorganic toner, which has higher light fastness, light fastness and corrosion resistance compared with organic toner, and is used in automobiles. The industry has obvious advantages.

Description

technical field [0001] The invention relates to the technical field of plastic processing and color matching, in particular to a brown 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 light conditions. There are three internal regulations in the automotive industry. Common light sources, namely D65, A and F11, the overall level of color matching 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, namely metamerism. For example, the overall color under natural light (...
