PET (polyethylene glycol terephthalate) color masterbatch

Abstract

The invention belongs to the technical field of high polymer materials, and particularly provides PET (polyethylene glycol terephthalate) color masterbatch. The PET color masterbatch is prepared from components in parts by weight as follows: 30-60 parts of PET vectors, 3-12 parts of turpentine oil, 5-15 parts of an anti-blocking agent, 10-20 parts of a slipping agent, 10-20 parts of an antistatic agent, 10-25 parts of pigments, 2-5 parts of a nucleating agent, 5-10 parts of liquid soap, 6-12 parts of an antioxidant, 15-25 parts of a flame retardant, 10-15 parts of a moisture-proof additive, 5-15 parts of polydimethylsiloxane, 2-10 parts of an antibacterial agent, 5-8 parts of low-molecular-weight polyethylene wax and 5-10 parts of a flatting agent. The preparation process is simple, the cost is lower, and the prepared color masterbatch has good coloring effect and less environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a PET color masterbatch. Background technique [0002] Polyethylene terephthalate (PET) is a crystalline polymer that is mainly used in synthetic fibers, electrical appliances due to its excellent mechanical strength, electrical insulation, heat resistance and chemical resistance. Collars such as insulating materials and films. At present, my country's PET output is about 20 million tons, one third of which needs to be colored, and the use of dyeing methods will bring 60 million tons of colored sewage discharge every year. There are three kinds of coloring methods: toner coloring, dyeing granule 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 and granulation c...

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 and granule coloring is to mix 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 effect of granule coloring has been greatly improved, but it needs to be experienced. Heating twice not only increases the production cost, but also damages the mechanical properties of the product to a certain extent
