Abstract

The invention provides a PA/ABS composite material. The PA/ABS composite material comprises the following components in parts by weight: 25-40 parts of ABS resin, 25-40 parts of nylon 6 resin, 30-60 parts of graphite fillers, 5-10 parts of conductive carbon black, 1-5 parts of a compatibilizer, 0.1-1 part of an antioxidant and 0.1-3 parts of a lubricant.

Description

technical field [0001] The invention belongs to the technical field of conductive composite materials, and in particular relates to a PA / ABS composite material and a preparation method thereof. Background technique [0002] Graphite is an excellent natural material. According to incomplete statistics, the world's natural graphite reserves are about 2 billion tons, of which crystalline graphite is about 800 million tons. China's natural graphite reserves rank first in the world, and the total reserves of crystalline graphite mines are 473 million tons. China has now formed a comprehensive natural graphite industry for mining, beneficiation, processing, purification and product series. China is the world's largest producer of natural graphite. In 2009, the production of natural graphite reached 1.7556 million tons. China's production accounts for about 55% of the world's total output, ranking first in the world. Developed countries reserve their own graphite resources as str...
