Corrosion-resisting and impact-resisting PVC cable material formula

Abstract

The invention discloses a corrosion-resisting and impact-resisting PVC cable material formula. The corrosion-resisting and impact-resisting PVC cable material formula is prepared from the following raw materials in parts by weight: 30 to 40 parts of PVC resin, 8 to 15 parts of natural rubber, 5 to 10 parts of composite polybenzoxazine material, 3 to 6 parts of metallocene ethylene-hexene copolymer, 3 to 7 parts of polyolefin elastomer, 0.5 to 1 part of lithium oxide, 1 to 3 parts of polystyrolsulfon acid, 1 to 2 parts of antioxygen, 2 to 5 parts of silicon carbide fiber, 1 to 3 parts of nanometer zirconium dioxide, 1 to 2 parts of silver-loaded zeolite, 2 to 5 parts of glass fiber, 4 to 10 parts of aluminum oxide, 5 to 10 parts of magnesium hydroxide, 1 to 3 parts of antiager, 3 to 6 parts of chlorinated paraffin, 3 to 5 parts of coupling agent and 1 to 4 parts of plasticizer. The cable material disclosed by the invention is modified by blending and crosslinking PVC with the natural rubber, so that wear resistance, an adhesive force and corrosion resistance of the PVC are greatly improved; the PVC and the composite polybenzoxazine material serve as film-forming materials, so that the wear resistance, impact resistance, corrosion resistance and adhesion property of a corrosion-resisting and impact-resisting PVC cable material are greatly improved.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a corrosion-resistant and impact-resistant PVC cable material formula. Background technique [0002] Wires and cables include bare wires, wires and cables for electrical equipment, power cables, communication cables and optical cables, and winding wires.

AI Technical Summary

Problems solved by technology

[0003] In the production process of marine cables, the corrosion resistance of cables is very high. Many existing cable materials use inferior raw and auxiliary materials. Although the conventional inspection indicators are qualified, long-term use will cause damage to copper wires.

Commonly used anti-corrosion additives are easy to corrode copper wire and oxidize and blacken, which seriously affects the performance of cables

How to suppress the occurrence of this phenomenon is very important for cable production; for some special industries, it needs to be used on heavy machinery, and it needs to follow the equipment to move continuously and keep in contact with the ground and wall lamp objects. Conventional cables cannot meet its requirements. Abrasion resistance and impact resistance requirements
