Problems solved by technology

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

Embodiment 1

[0013] A plastic coloring masterbatch, its components are proportioned by mass percentage: ethylene-vinyl acetate copolymer (EVA) 26%, carbon black 65%, low molecular weight polyethylene wax 8%, polyphenol antioxidant 1010 and sub Phosphate antioxidant 168 compound 1%, wherein, the specific surface area of ​​the carbon black is 150-300m 3 / g, the particle size is between 15nm and 25nm, and the pH value is 6-9.

[0014] Preparation method: mix each component according to the weight ratio, then mix in a high-speed mixer for 15 to 30 minutes, then use a twin-screw extruder to extrude and granulate, then dry and pack to obtain a plastic compound of the present invention. Color masterbatch.

Embodiment 2

[0016] A plastic coloring masterbatch, its components are proportioned by mass percentage: polyethylene (PE) 15%, carbon black 75%, montan wax 9%, polyphenol antioxidant 1010 and phosphite antioxidant 168 1% of the compound, wherein, the specific surface area of ​​the carbon black is 150-300m 3 / g, the particle size is between 15nm and 25nm, and the pH value is 6-9.

[0017] Preparation method: mix each component according to the weight ratio, then mix in a high-speed mixer for 15 to 30 minutes, then use a twin-screw extruder to extrude and granulate, then dry and pack to obtain a plastic compound of the present invention. Color masterbatch.

Abstract

The invention discloses a plastic color master batch and a preparation method thereof. The plastic color master batch comprises, by mass, 10-30% of a carrier, 50-80% of carbon black, 3-10% of a lubricant and 0.1-1% of an antioxidant. The plastic color master batch has the advantages of very good blackness, good dispersibility, less consumption, no untoward influences on the mechanical performances on plastic products, production technology simplification, convenient use, environmental pollution avoiding and time saving when the plastic color master batch is used in the coloring of the plastic products.

Description

technical field [0001] The invention relates to the field of plastic coloring, in particular to a plastic coloring masterbatch 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 t...
