Abstract

The invention provides antistatic and anti-bacteria PC / PBT (poly carbonate / polybutylene terephthalate) alloy and a preparation method thereof, and belongs to the field of polymer materials. The antistatic and anti-bacteria PC / PBT alloy is obtained by performing melt blending on PC (poly carbonate), PBT (polybutylene terephthalate) and MWCNT (multi-walled carbon nanotubes)-g-SiC-NH2-g-PBT master batches; and the MWCNT-g-SiC-NH2-g-PBT master batches are obtained by performing graft copolymerization on MWCNT-g-SiC-NH2, DBTO (dibutyl tin oxide) and the PBT. The prepared PC / PBT alloy has antistatic, anti-bacteria, high-temperature-resistant, high-hardness and wear-resistant characteristics, safety performance of an automobile can be improved effectively, by the preparation method, equipment such as an extruder can be protected, and the preparation method is easy and convenient to operate and suitable for industrialization.

Description

technical field [0001] The present invention relates to a modification technology in the field of polymer materials, in particular to a modified PC / PBT alloy and a preparation method thereof. The alloy material contains MWCNT-g-SiC-NH 2 (Amino-modified silicon carbide graft-coated modified multi-walled carbon nanotubes), with antistatic, antibacterial, temperature-resistant, high-hardness and wear-resistant properties. Background technique [0002] PC / PBT alloy has good heat resistance, impact resistance and toughness, and is easy to process. It is an ideal material for manufacturing automotive fuel tank caps, handles, radiator grilles and other components. People often pay attention to the temperature resistance of these components and continuously improve them, while ignoring the influence of other properties on automobile safety. The antistatic properties of materials also play a very important role in automobile safety, especially for products such as fuel tank caps. Ma...
