Abstract

The invention relates to a macromolecular material and a preparation method thereof, in particular to a PBT (polybutylece terephthalate) composite material and a preparation method thereof. The PBT composite material comprises the following components in percentage by weight: 20-25 percent of polybutylene terephthalate, 6-20 percent of bromine containing flame retardant, 5-15 percent of phosphorus and nitrogen containing flame retardant, 5-15 percent of inorganic flame retardant, 20-40 percent of glass fiber, 2-8 percent of toughening agent, 0.2-0.4 percent of antioxidant and 0.3-2 percent of lubricating dispersant. The preparation method comprises the following steps of weighing the components in the percentage by weight; putting plastic and adjuvant into a high-speed mixing machine, mixing the plastic and the adjuvant for 2-5 minutes and discharging a mixture; controlling a double-screw extruder to extrude and granulate the mixture; and adding glass fiber in the extruding process to obtain the PBT composite material. The flame-retardant property and the strength of the PBT composite material are obviously improved; using requirements of more occasions can be met; the PBT composite material has high application value and good market prospect; and the used raw materials are the conventional products in the field of engineering plastics and are low in cost.

Description

technical field [0001] The invention relates to a polymer material and a preparation method, in particular to a PBT composite material and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT) is a thermoplastic engineering plastic widely used at present. It is widely used in electronic appliances because of its excellent heat resistance, weather resistance, and chemical resistance. With the development of modification technology, glass fiber reinforcement and mineral filling can effectively improve the shrinkage defect and greatly increase its application range. [0003] After its flame retardant modification, it is widely used in low-voltage electronic and electrical components. With the EU's increasingly stringent glow wire standards for electronic products in extreme environments, from the initial 750°C for 30s to the current 850°C for 30s, it can be seen that the resistance The fuel standards are gradually increasing. Therefore, ...
