Modified polyvinyl chloride cable sheath material capable of resisting ultraviolet radiation aging

Abstract

The invention relates to a cable material, specifically to a modified polyvinyl chloride cable sheath material capable of resisting ultraviolet radiation aging. The material comprises the following raw materials by weight: 50 to 60 parts of polyvinyl chloride, 30 to 40 parts of calcium carbonate, 2 to 3 parts of an anti-oxidant 1035, 2 to 3 parts of propylene glycol, 4 to 5 parts of potash feldspar powder, 12 to 14 parts of nanometer titanium dioxide, 1 to 2 parts of copper oxide powder, 1 to 2 parts of calcium lignin sulphonate, 10 to 12 parts of rosin pentaerythritol ester, 23 to 26 parts of tributyl citrate, 1 to 2 parts of 2-mercaptobenzimidazole, 1 to 3 parts of vinyltris(beta-methoxyethoxy)silane, 1 to 2 parts of oleamide, 23 to 25 parts of dolomite, 10 to 12 parts of bauxitic clay and 14 to 16 parts of an auxiliary agent. According to the invention, the cable sheath material improves performance of traditional polyvinyl chloride materials and has improved mechanical properties; nanometer titanium dioxide can assist the material in resisting ultraviolet radiation aging; and the prepared material has heat resistance, stable properties, resistance to weathering and long service life, can be widely applied to preparation of a variety of cable sheath insulating materials and is greatly needed in market.

Description

technical field [0001] The invention relates to a cable material, in particular to a modified polyvinyl chloride cable sheath material with anti-ultraviolet aging and a preparation method thereof. Background technique [0002] 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, and continuous improvement of the performance of sheath materials is an urgent need for economic and social development. Traditional sheath materials often have poor flame retardancy, poor chemical stability, high temperature deformation, poor mechanical properties, and short service life. And other problems, bring a lot of inconvenience to the actual use, and even threaten people's life and property safet...

[0002] 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, and continuous improvement of the performance of sheath materials is an urgent need for economic and social development. Traditional sheath materials often have poor flame retardancy, poor chemical stability, high temperature deformation, poor mechanical properties, and short service life. And other problems, bring a lot of inconvenience to the actual use, and even threaten the safety of people's lives and property. Therefore, it is urgent to change the original sheath material formula and improve the material performance to meet the diverse needs of the cable market.
