Abstract

The invention relates to the technical field of high polymer materials, and discloses a high-surface-gloss environment-friendly halogen-free flame-retardant PBT (polybutylene terephthalate) composite material and a preparation method thereof. The preparation method comprises the following steps: blending PBT used as the main raw material with PET (polyethylene terephthalate), toughener, halogen-free flame retardant, high-gloss black seed, antioxidant, lubricant, glass fiber and coupling agent, carrying out melt extrusion, and granulating. The invention has the advantages of wide raw material sources, favorable technical adaptability and low production cost; the obtained engineering plastic product has the advantages of high surface gloss and excellent material properties, and the impact strength reaches 8.2 KJ/m<2> above; the sample thickness is 1.6mm, and the flame retardancy can reach UL94V-0; and less black smoke and toxic gas are generated in the combustion process, and thus, the composite material achieves the environment-friendly level.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-gloss surface environment-friendly halogen-free flame-retardant PBT composite material and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT), also known as polyester, was successfully researched by Celanese Company of the United States in the early 1970s, and was listed under the trade name of Celanex, and then many manufacturers put into the ranks of producing PBT. PBT has the advantages of heat resistance, weather resistance, chemical resistance, excellent electrical performance, small water absorption, good surface, etc., and is widely used in electronics, automobiles, machinery, household appliances, etc., especially in the electronics / electrical industry, and Most of the materials in this industry have flame retardant requirements. [0003] For a long time, the PBT flame retardant system is mainly halogenated flame...
