Easily peeled PVC (Polyvinyl Chloride) cable sheath material and preparation method thereof

Abstract

The invention belongs to the field of cable materials, and in particular relates to an easily peeled PVC (Polyvinyl Chloride) cable sheath material which is mainly prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 3-8 parts of anti-impact modifying agent, 45-50 parts of plasticizing agent, 0.1-0.5 part of antioxidant, 3-10 parts of fluorine lubricant, 3-7 parts of thermal stabilizing agent, 25-35 parts of filling agent and 15-20 parts of flame retardant. The easily peeled PVC cable sheath material provided by the invention is excellent in mechanical physical property, and meanwhile a product meets the environment-friendly requirements; due to addition of the fluorine lubricant, a cable sheath layer has good release properties with an insulating layer, and when being recycled, the insulating layer and the sheath layer can be easily separated.

Description

technical field [0001] The invention belongs to the field of cable materials, and in particular relates to an easily peelable PVC cable sheath material with high recycling efficiency and a preparation method thereof. Background technique [0002] In modern society, wires and cables can be seen everywhere, such as wires and broadband access lines used in homes and hotels; power cables and overhead cables laid by power departments, etc. Wires and cables play a very important role in national economy and social activities. status. With the rapid development of the economy, the wire and cable industry has become the second largest industry in my country. With the increasing development of life, various power systems and electrical appliances are updated and eliminated, and a large number of waste cables will be produced every year. The main components of waste cables include copper, aluminum, plastic, rubber, etc., which have a very high recycling rate. value. If a large numb...

AI Technical Summary

Problems solved by technology

When the cable is recycled, its conductive layer and non-conductive layer need to be separated and recycled. The non-conductive layer of the cable is divided into an insulating layer and a sheath layer. It is not easy to separate the insulating layer and the sheath layer in existing cables.

For this reason, someone has invented processing equipment dedicated to wire and cable recycling. For example, the utility model patent with the authorized announcement number CN202363822U provides a waste cable stripping recycling processing equipment. However, this equipment focuses on cables of various shapes. The recycling of the wire is not specifically aimed at the separation of the insulating layer and the sheath layer that are not easy to peel off and recycled.
