Abstract

The invention discloses a safe antistatic oil-proof modified PVC (polyvinyl chloride) cable sheath material and a preparation method thereof. The invention is characterized in that the cable sheath material is prepared from the following raw materials in parts by weight: 66-69 parts of polyvinyl chloride resin, 13-15 parts of carbon nanotube, 10-13 parts of dioctyl terephthalate, 13-14 parts of acrylic acid, 2-3 parts of calcium carbonate, 2-3 parts of antimony trioxide, 0.02-0.03 part of azodiisobutyronitrile, 1-1.2 parts of titanate coupling agent TC-2, 2-3 parts of tallow, 1-2 parts of stearic acid, 2.5-3.5 parts of vinyl trimethoxy silane, 1-2 parts of dibenzoyl peroxide and 7-9 parts of assistant. The carbon-nanotube-base polymer is utilized to modify the PVC, thereby enhancing the mechanical properties and electric properties of the product. The product is electrically conductive, and can leak static electricity on the surface in time, thereby preventing potential safety hazard. The assistant is added to enhance the wear resistance and flexibility of the product, and the product has favorable processing flowability and favorable dispersity. The cable sheath material has bending resistance, and can be recycled.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a safe antistatic oil-resistant modified PVC cable sheath material and a preparation method thereof. Background technique [0002] The existing cable materials are various and suitable for various purposes. Safety anti-static oil-resistant cable is a signal cable suitable for use in special environments. It needs to work frequently in gasoline or diesel pools. It must be anti-static, oil-resistant, bending-resistant, and wear-resistant at the same time. In the prior art, polyurethane and other elastomers are used to make such special cable materials, but the cost is high. Through research, the present invention decides to modify PVC with carbon nanotube-based polymers to obtain safe anti-static and oil-resistant cable materials. . The hardness of carbon nanotubes is equivalent to that of diamond, but it has good flexibility and can be stretched. Adding carbon nanotubes can greatl...
