Problems solved by technology

Traditional sheath materials often have problems such as poor flame retardancy, poor chemical stability, high temperature deformation, poor mechanical properties, and short service life, especially in areas with high temperature, rainy, ultraviolet rays, and strong ozone. cracks and other aging phenomena, and aging further accelerates the deterioration of the mechanical properties of the cable sheath such as insulation and tensile strength, which seriously affects the performance of the cable and brings a lot of inconvenience to actual use. Therefore, it is urgent to change the original sheath material formula , improve material properties to meet the diverse needs of the cable market

Abstract

The invention belongs to the technical field of an electric material and provides an anti-aging cable sheath material and a preparation method thereof. The cable sheath material comprises the following raw materials in parts by weight: 52-64 parts of modified polyurethane resin, 13-22 parts of chlorinated polyethylene, 7-22 parts of dibutyl maleate, 12-19 parts of organic nanometer montmorillonite, 2-5 parts of bocour blue, 2-5 parts of chlorinated paraffin, 1-4 parts of an anti-aging agent, 0.6-2.8 parts of a coupling agent, 1.3-3.4 parts of an ultraviolet light absorber and 1.6-2.9 parts of a plasticizer. The cable sheath material provided by the invention has an anti-aging property. The modified polyurethane resin is used as a main raw material, and the organic nanometer montmorillonite, bocour blue, chlorinated paraffin, anti-aging agent and ultraviolet light absorber are used as auxiliaries, so that the prepared cable sheath material has an excellent anti-aging property.

Description

technical field [0001] The invention belongs to the technical field of power materials, and in particular relates to an anti-aging cable sheath material and a preparation method thereof. Background technique [0002] The cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and isolating the copper wire from water, air and other media to avoid leakage. With the development of the economy, the places where cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators of cable sheath materials, such as insulation, tensile strength, service temperature, flame retardant performance and other indicators There are strict requirements. Traditional sheath materials often have problems such as poor flame retardancy, poor chemical stability, high temperature deformation, poor mechanical properties, and short servi...
