Abstract

The present invention discloses a flame-retardant polybutylene telephthalate composite material and a preparation method thereof. The flame-retardant polybutylene telephthalate composite material comprises the following components in mass percentage: 60% to 85% of PBT, 5% to 15% of glass fibers, 5% to 12% of flame retardant, 1% to 3% of antistatic agent, 0.5% to 2% of anti-aging agent, 2% -6% of plasticizer, 0.1% to 0.5% of antioxidant, and 0.1% to 1% of lubricant. The flame retardant is in the form of a compound composed of PSPPP, PDMS and nano-montmorillonite in the mass ratio of 4:2:1. According to the invention, the flame-retardant polybutylene telephthalate composite material is excellent in flame retardancy, mechanical property and hThe invention eat resistance, small in warping deformation, good in size stability, high in strength, good in chemical resistance, smooth and clean in product surface, simple in preparation process, low in production cost and easy to popularize.
