Embodiment 1

[0017] A color masterbatch for plastics, its components are proportioned by mass percentage: titanium dioxide (titanium dioxide) 70%, polypropylene (PP) 18%, ethylene-octene copolymer (POE) 10%, low molecular weight polyethylene Wax 1.2%, hindered phenol antioxidant 1076 and phosphite antioxidant 168 compound 0.8%.

[0018] 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 the plastic coloring agent of the present invention. Masterbatch.

Embodiment 2

[0020] A color masterbatch for plastics, its components are proportioned by mass percentage: 80% of azo pigment, 10% of ethylene-vinyl acetate copolymer (EVA), 8% of styrene-maleic anhydride copolymer (SMA) %, OP wax 1.5%, hindered phenol antioxidant 1076 and phosphite antioxidant 168 compound 0.5%.

[0021] 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 the plastic coloring agent of the present invention. Masterbatch.

Embodiment 3

[0023] A color masterbatch for plastics, the components of which are: carbon black 60%, ethylene-vinyl acetate copolymer (EVA) 24%, methyl methacrylate-glycidyl methacrylate-propylene ethylene Ester terpolymer (MGE) 15%, OP wax 0.8%, hindered phenol antioxidant 1076 and phosphite antioxidant 168 compound 0.2%.

[0024] 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 the plastic coloring agent of the present invention. Masterbatch.

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...
