Abstract

The invention discloses a polybutylece terephthalate (PBT) reinforced material with high thermal conductivity. The PBT reinforced material comprises the following components in percentage by mass: 30-40% of PBT resin, 12-16% of phenolic resin, 5-10% of polycarbonate, 6.5-8.2% of heat-conducting powder, 4.2-5.3% of heat-conducting filler, 2.87-3.65% of a fire retardant, 2.12%-2.56% of an anti-hydrolysis agent, 1.86%-2.24% of a wear-resistant agent, 3.45-4.26% of an antioxidant, 2.34-3.28% of a toughening agent, and the balance of a heat-conducting adhesive. The formula of the PBT reinforced material is more scientific and reasonable. According to the PBT reinforced material with high thermal conductivity, the PBT resin is taken as a main raw material, and the phenolic resin and the polycarbonate are added cooperatively, so that insulation performance of the material can be improved; the heat-conducting powder, the heat-conducting filler and the heat-conducting adhesive are added, so that heat conduction performance of the material can be greatly enhanced; wear resistance and surface strength of the material can be improved through the cooperative addition of the wear-resistant agent; and toughness of the material can be reinforced through the cooperative addition of the toughening agent, so that the formed material does not fracture easily, overall performance of the PBT material can be enhanced, and therefore, a good popularization effect is achieved.
