Polyvinyl chloride cable material

Abstract

The invention relates to a polyvinyl chloride cable material with excellent performance, which is composed of the following components in parts by weight: 100 parts of polyvinyl chloride resin, 25 parts of inorganic filler, 4 parts of triphenyl phosphate, and 10 parts of epoxy oil Butyl acid, 24 parts of aluminum hydroxide, 0.6 parts of antioxidant 1010, 1.8 parts of antioxidant 1024, 2 parts of magnesium oxide, 3 parts of zinc oxide, 2 parts of stearic acid, 0.6 parts of aluminate coupling agent. The cable material has excellent weather resistance, cold resistance, aging resistance and excellent oxygen and copper resistance.

Description

technical field [0001] The invention relates to a cable material, especially a polyvinyl chloride cable material with excellent properties. Background technique [0002] In the cable production process, the oxidation and discoloration of copper conductors is a long-standing problem. The conventional solution is to use physical methods to block the contact between copper and air, and to use chemical methods to form a passivation film to block the oxidation of copper conductors. Thermoplastic insulators normally have no effect on copper wire oxidation. However, many existing cable materials use low-quality raw and auxiliary materials. Although the conventional inspection indicators are qualified, long-term use will cause damage to the copper wire. Commonly used PVC plasticizers, such as dioctyl phthalate, dioctyl sebacate, diundecyl phthalate, trioctyl trimellitate, chlorinated paraffin, etc., all have free acid ion precipitation , corrode the copper wire and oxidize and bla...

AI Technical Summary

Problems solved by technology

However, many existing cable materials use inferior raw and auxiliary materials. Although the conventional inspection indicators are qualified, long-term use will cause damage to the copper wire.

Commonly used PVC plasticizers, such as dioctyl phthalate, dioctyl sebacate, diundecyl phthalate, trioctyl trimellitate, chlorinated paraffin, etc., all have free acid ion precipitation , corrode the copper wire and oxidize and blacken, which seriously affects the performance of the cable
