Abstract

The invention is applicable to the technical field of composite materials and provides a PBT (polybutylece terephthalate) composite material and a preparation method thereof. The polybutylece terephthalate composite material comprises the following components in parts by weight: 5 to 35 parts of an TPEE (Thermoplastic Polyeher Ester Elastomer), 10 to 82 parts of PBT, 5 to 35 parts of a reinforcing agent, 5 to 25 parts of a flame retardant, 3 to 7 parts of a compatilizer and 0.1 to 2 parts of a coupling agent. According to the invention, the low-temperature resistance of the PBT composite material can be enhanced remarkably through adding the TPEE, and meanwhile, the consistency of the TPEE, the PBT, the reinforcing agent and the flame retardant is modified through the compatilizer and the coupling agent, so that the influence of the reinforcing agent and the flame retardant to the low-temperature resistance of the composite material can be eliminated effectively, and the purpose that the PBT composite material has low-temperature resistance, flame retardancy and high intensity at the same time can be achieved. In addition, when the PBT composite material is prepared, all that is needed is to perform melt extrusion after the corresponding components are mixed step by step. The method is simple in process, low in cost, high in productivity effect and very suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a PBT composite material and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT) has the characteristics of excellent thermal stability, creep resistance, electrical insulation and flame retardancy. It is a general-purpose engineering plastic with excellent performance. The country has formed industrialized production, and the technology continues to develop. The performance of unmodified PBT is not good, and PBT needs to be modified for practical application. Among them, glass fiber reinforced modified grades account for more than 70% of PBT. PBT reinforced materials have excellent performance and are currently widely used. It is mainly used to make parts of electronic appliances, automobiles, mechanical equipment and precision instruments, and has replaced metal materials such as copper, zinc, aluminum and iron ...
