Tear-resistant cable insulation material and preparation method thereof

Abstract

The invention discloses a tear-resistant cable insulation material and a preparation method thereof. The preparation method can obviously reduce the roller sticking phenomenon in the mixing process, reduce the actual operation time, improve the preparation efficiency, reduce the risk of raw material aging, and produce a product with low temperature resistance, high strength and aging resistance. The tear-resistant cable insulation material has the advantages of low temperature resistance, high strength and aging resistance. The preparation method has strong operability, obvious effects and a high promotion and application value.

Description

technical field [0001] The invention relates to cable insulating materials, in particular to a tear-resistant cable insulating material and a preparation method thereof. Background technique [0002] At present, with the development of science and technology, both industry and human daily life are developing in the direction of electrification, and the status of cables in the field of industry and power is gradually increasing. Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, aluminum alloy cables and so on. The cable is usually a rope-like cable twisted by several or several groups of wires, and each group is twisted with at least two wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulated The outer sheath is used to connect circuits,...

[0004] However, due to the addition of a large amount of additives and fillers during the preparation process, the sticky roll phenomenon occurs during the preparation process, and the sticky roll further leads to uneven mixing and uneven performance of rubber products. In addition, the preparation process requires multiple Cleaning the sticky rollers will lead to a long preparation time, and the prolongation of the mixing time will further cause the aging of the rubber raw materials, increasing the risk of the strength and performance of the prepared rubber products. On the other hand, the sticky rollers will lead to uneven mixing of raw materials, resulting in rubber Part of the product has better performance, but some performance cannot meet the requirements

However, if the amount of filler is reduced, although the sticking phenomenon will be reduced, the performance of the rubber will be reduced, which does not meet the requirements of field composite rubber with anti-aging, high strength and low temperature resistance.

[0005] At present, the outer sheath of the cable made of the outer sheath of the cable will lose its elasticity and become more brittle at extremely low temperatures, and cannot withstand repeated movements or bending, so that the cable is discarded and cannot be used.
