Color master batch for plastic cement and preparation method thereof

Abstract

The invention discloses black master batch for plastic cement and a preparation method thereof. The color master batch for plastic cement is prepared from the following components by mass percentage: 60-80% of pigment, 10-30% of carrier, 5-15% of compatibilizer, 0.1-2% of dispersant, and 0.1-1% of anti-oxidant. The beneficial effects reside in that: when used for coloring a plastic cement product, the color master batch provided by the invention has characteristics of good dispersibility, uniform coloring, high concentration, small usage amount and no influence on mechanical properties of the plastic cement product; and in secondary usage, the color master batch provided by the invention simplifies a production technology process co-mixed with the plastic cement raw material, avoids environment pollution, and has advantages of convenient usage, easy coloring, and time and raw material saving.

Description

technical field [0001] The invention relates to the field of plastic coloring, in particular to a color masterbatch for plastics and a preparation method thereof. Background technique [0002] Plastic is mainly composed of carbon, oxygen, hydrogen and nitrogen and other organic or inorganic elements, and can be formed into plastic products of various shapes and colors. It has been widely used in every field of modern life, such as household appliances, instruments Apparatus, wire and cable, construction equipment, communication electronics, automobile industry, aerospace, daily hardware, etc. There are three kinds of coloring methods for producing plastic products in the prior art: toner coloring, dyeing and pulling grain coloring and masterbatch coloring. When directly using toner for coloring, the coloring is very simple, but it has the disadvantages of easy to produce color spots, difficult to control color difference, and great environmental pollution. Dyeing Dyeing is...

When directly using toner for coloring, the coloring is very simple, but it has the disadvantages of easy to produce color spots, difficult to control color difference, and great environmental pollution

Dyeing Dyeing is to mix plastic raw materials and toner and then use mixing equipment such as twin-screw extruder for melt blending and coloring. Compared with coloring with toner, the coloring effect of granules has been greatly improved, but the plastic It needs to be heated twice, which not only increases the production cost, but also damages the mechanical properties of the product to a certain extent
