Problems solved by technology

However, due to the large variety of resins, there is no universal carrier resin. Once the resin with poor compatibility is used, it will have an adverse effect on the product.
Secondly, due to the existence of the carrier, the color content in the masterbatch is low, the amount of the masterbatch is large, the coloring degree is not good, and it is difficult to make high-quality products

Abstract

The invention provides a carrier-free high-gloss oil black color master batch as well as a preparation method and application thereof. The raw materials comprise the following components in parts by weight: 35-50 parts of carbon black, 30-45 parts of dye, 15-25 parts of a dispersing agent and 1-5 parts of an antioxidant. The preparation method disclosed by the invention eliminates adverse effects caused by carrier resin, so that the product is good in dispersity, high in color fastness and excellent in coloring effect, is high in luminosity, free of marks on the surface, free of hard spots and oil black in color after application.

Description

technical field [0001] The invention relates to the technical field of color masterbatches, in particular to a carrier-free high-gloss oil black masterbatch and its preparation method and application. Background technique [0002] Masterbatch coloring is the most common plastic coloring method nowadays. Packaging, construction, automobile industry and other industries are inseparable from masterbatch coloring. The huge demand also promotes the rapid development of the color masterbatch market. The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading super-normal pigments in the resin, so its coloring power is higher than that of the pigment itself. With the development of society, consumers pay more and more attention to the beauty and environmental protection of products, and put forward higher requirements for masterbatches. However, relying on the carrier characteristics of color masterb...
