Abstract

The invention relates to the field of conducting composite materials, particularly a high-strength PVC (polyvinyl chloride) conducting composite material and a preparation method thereof. The high-strength PVC conducting composite material is prepared from the following raw materials in percentage by weight: 15-18% of carbon black, 0.2-0.5% of manganese powder, 0.5-0.8% of iron powder, 2.0-3.0% of copper powder, 0.1-0.2% of zirconium powder, 1.6-1.8% of nickel powder, 0.05-0.2% of titanium white, 0.5-1.0% of dispersing agent and the balance of PVC powder. The preparation method comprises the following steps: proportionally and evenly mixing the raw materials, oscillating in an oscillation tank for 100-120 minutes until the components are uniformly dispersed into the PVC matrix, taking out the oscillated reaction product, filling into a mold of a flat vulcanizing machine, carrying out high-temperature hot pressing, and demolding to obtain the high-strength PVC conducting composite material. The high-strength PVC conducting composite material has the advantages of favorable conductivity and favorable tensile strength. The preparation method has the advantages of high reaction efficiency, energy saving, no industrial waste, low production cost and favorable market prospects.

Description

technical field [0001] The invention relates to the field of conductive composite materials, in particular to a high-strength PVC conductive composite material and a preparation method thereof. Background technique [0002] PVC (polyvinyl chloride) is one of the five general-purpose resins, with a huge production volume at home and abroad and a wide range of applications. A large part of products in daily life are made of PVC, but its own defects, such as electrical insulation and low mechanical strength, greatly limit its application range. The preparation of insulating PVC into a composite material with good electrical conductivity and high strength will expand the application of PVC in integrated circuits, chemical equipment, outer packaging materials, aerospace and other fields. [0003] In terms of the preparation method of the PVC conductive composite material, the PVC matrix and the carbon black powder are mixed and plasticized according to a certain ratio by an int...
