Abstract

The invention discloses a flame-retardant anti-electric leakage high-performance environment-friendly PBT (polybutylene terephthalate) material and a preparation method thereof. The flame-retardant anti-electric leakage high-performance environment-friendly PBT material comprises the following components in percentage by mass: 45-60% of PBT, 18-25% of organic phosphorus flame retardant, 0.5-2% of calcium oxide, 15-35% of alkali-free glass fiber, 0.1-0.6% of antioxidant, 0.3-1% of lubricant, 1-5% of flexibilizer and 0.2-1.5% of silane coupling agent. The PBT material disclosed by the invention has the beneficial effects that by adopting calcium oxide as a synergist of the PBT material, the electric leakage resistance can be remarkably improved; by adding less than 2% of the PBT material and blending with 18-25% of organic phosphorus flame retardant, vertical burning can be guaranteed to meet the V0-level flame retardance requirement, the flame retardance is good, the thermal stability is high, little influence is brought to the mechanical strength, etc.; the preparation method disclosed by the invention has the advantages of simplicity and easiness in operation.

Description

technical field [0001] The invention relates to a PBT material and a preparation method thereof, in particular to a flame-retardant, leakage-resistant, high-performance and environment-friendly PBT material and a preparation method thereof. Background technique [0002] The English name of PBT is Polybutylece Terephthalate, and the Chinese name is polybutylene terephthalate or polybutylene terephthalate. It belongs to the polyester series and is composed of 1,4-butanediol and terephthalic acid ( PTA) or terephthalate (DMT) polycondensation, and a milky white translucent to opaque, crystalline thermoplastic polyester resin made through a mixing process. Due to the -CH2- chain growth of PBT resin, the molecular chain is easy to bend, so the glass transition temperature is lower than that of PET, and the curing speed is fast. PBT is a crystalline, high molecular weight polymer with excellent physical properties and processability. Because of the rapid crystallization of the m...
