Abstract

The invention provides a halogen-free flame-retarding polyester master batch specially used for simulative hairs, which includes 20-60 parts of PET resin, 15-60 parts of PBT resin, 30-60 parts of a halogen-free flame retardant, 1-5 parts of a lubricant, 0.2-1 part of an anti-dripping agent, 3-10 parts of an inorganic material, and 0.1-2 parts of a coupling agent. The inorganic material is one or more selected from SiO2, montmorillonoid, calcium carbonate and barium sulfate. The coupling agent is a silane coupling agent. The invention also provides a preparation method of the master batch, which includes the steps of: mixing the components in a high-speed mixer with material cylinder temperature being 60-120 DEG C; performing extrusive granulation to the mixed components through a twin-screw extruder. The preparation method is simple and is easy to carry out. The halogen-free flame-retarding polyester master batch, when being used for simulative hairs, especially high-temperature hairs, has excellent spinnability and combability, has good hand feel and shaping-ability, is good and durable in flame retarding effect, is low-smoke and toxic-free and has good charcoal-forming property.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant polyester masterbatch for artificial hair and a preparation method thereof. Background technique [0002] Polyester (PET) fiber has developed rapidly due to its advantages of high modulus, high strength, elasticity, good shape retention and heat resistance, and has become the fiber variety with the largest output and widest application in synthetic fibers. In addition to its use as textiles, its use in high-end artificial wigs has also increased day by day in recent years. However, due to some deficiencies in the material itself, the wigs produced by ordinary PET do not have the matteness, proper elasticity and flame retardancy of the hair. As a major exporter of high-end artificial wigs, my country relies almost entirely on imports of raw materials for the production of flame-retardant artificial hair to meet the flame-retardant requirem...
