[0002] Polybutylene terephthalate (PBT) is a thermoplastic engineering plastic, which has been widely used in electronic appliances, home appliances, automobile industry and other fields, but due to its poor low-temperature impact toughness and high notch sensitivity at room temperature, No flame retardant effect and anti-static resistivity up to 10 -15-20 The shortcomings of high insulating materials such as Ω have great restrictions on the application of electronic products, and it is seriously difficult to control the hazards of static electricity: during use, it may cause heavy losses to human body discharge or products of various industries and disasters such as ignition and explosion, but at present In the past 20-30 years, various industries in China have used traditional (carbon-based) electrostatic conductive products in the application, such as (carbon-based) acetylene black, graphene, carbon fiber and other blended materials. In the process of turnover transportation, the carbon-based dust on the surface is micron-level after friction, collision and scratches: instant take-off and electrification enters the microelectronic components, causing defects such as easy circuit breakage of products in the electronic system due to electrostatic breakdown. With the continuous development of electronic technology, Innovation and new electrostatic materials are changing with each passing day. Carbon-based (black) materials are replaced by natural-color electrostatic materials. This project develops a PBT electrostatic material and its preparation method and application (natural color) to adjust the color without affecting the material (physics, mechanics) Equal performance, clean and beautiful appearance, permanent stable volume resistance and surface resistance, moderate price, simple process, and incomparable with traditional (carbon series) electrostatic materials in quality and cleanliness, breaking the reliance on imported white electrostatic materials for several years and High-priced and monopoly products, involving independent innovation in this field PBT composite electrostatic material is an important key point that needs to be solved urgently
