Abstract

The invention relates to a quaternary compound color master batch and a preparation method thereof. The quaternary compound color master batch mainly comprises red, yellow, green and blue toner. According to the scheme of compounding the quaternary toner with the color master batch, the color effect of the carbon black is perfectly copied in light-color and white plastics, and the black spot appearance problem caused by the characteristics of small primary particle size, easiness in agglomeration and difficulty in dispersion of the carbon black is fundamentally solved; meanwhile, the compoundcolor master batch is more excellent in dispersion effect, color control is more convenient, raw materials are cheap and easy to obtain, and extra cost is not increased in production.

Description

technical field [0001] The invention belongs to the field of plastic products, in particular to a quaternary composite color masterbatch and a preparation method thereof. Background technique [0002] In the production of light-colored modified plastic pellets, in order to facilitate color difference control and production process control, a certain amount of low-concentration diluted carbon black is often added to the toner formula. Typical carbon black is made of diameter 10-100nm, specific surface area 5-1500m 2 / g of spherical primary particles, the particle size of carbon black is very fine, and the specific surface area is large, which determines that the dispersion of carbon black is poor during use, so that black spots will be generated during subsequent processing. Carbon black is the main source of heterochromatic points in light-colored modified plastics. Modified plastic materials containing more than specified heterochromatic points can only be judged as defect...
