Static-free low-wrap cold-resistant heat-resistant low-cost polypropylene composite material and preparing method thereof

Abstract

The invention relates to a static-free low-wrap cold-resistant heat-resistant low-cost polypropylene composite material. The material is prepared from the following components in percentage by weight: 30-60 percent of polypropylene, 8-18 percent of conductive material, 20-60 percent of talcum powder and glass microballoons, 0.3-1.5 percent of coupler, 5-15 percent of tougher, a suitable amount of disperser and others. The preparation method of the composite material comprises the following steps of: premixing and treating the conductive material, the talcum powder, the glass microballoons, the coupler and the disperser in a high-speed mixer for 8-10 min; then, adding polypropylene and the toughener and mix at a high speed for 8-10 min; storing the mixture in a charging barrel of a pelletizer; and mixing, extruding and pelletizing with a double-screw extruder. Products which are made from the material by adopting a plastic injection technology can be continuously used at 20 DEG C below zero to 120 DEG C and can be used as semiconductors and static-free production technology equipment and products in the petrochemical industry, military, the aerospace and aviation industry and the IT (Information Technology) industry as well as static-free devices and tools for production and living.

Description

1. Technical field [0001] The invention relates to an antistatic (conductive) low-warping heat-resistant and cold-resistant low-cost polypropylene composite plastic material and a manufacturing method, which are especially suitable for antistatic overlapping materials used in cold regions and high-heat environments. 2. Technical background [0002] Due to the extensive use of polymer insulating materials that are prone to generate and accumulate static electricity in modern life and production, it is very common to generate voltages from 2KV to 60KV. Due to the accumulation of a large amount of static electricity, sparks generated by electrostatic discharge or the action of electrostatic electric field force, it is easy to cause combustion and explosion of easy-to-enene objects and explosive gases, interfere with the normal operation of radio equipment, and make the aircraft deaf and blind; due to electrostatic attraction Dust makes the medicines not reach the standard purit...
