Abstract
A PBT composite material having high heat resistance and high gloss for a vehicle mirror and a method for preparing the same are provided. The PBT composite material includes 57.2-88.9 wt % of PBT, 5-20 wt % of PET, 5-20 wt % of calcium silicate, 0-10 wt % of coupling agent-modified talc, 0.1-0.3 wt % of an antioxidant, 0.5-1.5 wt % of a flowing aid and 0.5-1.0 wt % of a nucleating agent. In the preparing method, the above components are placed into an extruding machine to perform a melt plasticization, and a molten material extruded by a die head of the extruding machine is water-cooled and stretched into a stripe to be granulated. The resulting PBT composite material has an excellent heat resistance and a good surface gloss and is suitable for manufacturing a high heat-resistant and high gloss vehicle mirror.
