Abstract

The invention relates to the technical field of color masterbatches, and in particular relates to a highly cold-resistant and toughening color masterbatch and a preparation method thereof. The color masterbatch comprises the following raw materials in parts by weight: 45-61 parts of polypropylene resin, 32-53 parts of toner, 2-7 parts of a dispersing agent and 1-5 parts of a cold-resistant and toughening agent, wherein polypropylene is a mixture of co-polypropylene and homo-polypropylene which are in a weight ratio of 1 to 1.4-2.2, and the cold-resistant and toughening agent is a mixture of an amide Beta crystal form nucleating agent and a dicarboxylate Beta crystal form nucleating agent which are in a weight ration of 1 to 1.2-1.8. The highly cold-resistant and toughening color masterbatch has an obvious toughening effect and higher impact strength at a low temperature of -20 DEG C than normal temperature; in addition, the rigidity of the highly cold-resistant and toughening color masterbatch is improved obviously at normal temperature; the addition of the color masterbatch is small; the color masterbatch is convenient and flexible to use and add. The preparation method of the color masterbatch and materials provided by the invention are used together so that the materials can take full effect; the process is simple and convenient to operate and control; the quality is stable, the production efficiency is high, and large-scale industrial production can be realized.

Description

technical field [0001] The invention relates to the technical field of color masterbatches, in particular to a highly cold-resistant and toughened color 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 enviro...
