Problems solved by technology

Masterbatch coloring has the advantages of good dispersibility, no pollution and convenient use, and overcomes the problems of color points, color difference and production environment pollution that exist in direct coloring with toner. However, polytrimethylene terephthalate masterbatches are more With PTT resin as the carrier, PTT resin has poor heat resistance, and it will change color after many times of heat history, which hinders the development of polytrimethylene terephthalate masterbatch

Description

technical field [0001] The invention relates to a poly(trimethylene terephthalate) toughened color masterbatch and a preparation method thereof, belonging to the technical field of macromolecules. 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 environm...
