Modified oilproof aging-resistant polyvinyl chloride cable sheath material

Abstract

The invention relates to a cable material, and in particular relates to a modified oilproof aging-resistant polyvinyl chloride cable sheath material which is prepared from the following raw materials in parts by weight: 24 to 28 parts of SG-1 polyvinyl chloride, 20 to 24 parts of POE (Polyolefin Elastomer), 5 to 8 parts of low-density polyethylene, 6 to 9 parts of antimonous oxide, 2 to 3 parts of Ca-Zn stabilizing agent, 2 to 3 parts of nylon fiber, 8 to 10 parts of coumarone, 2 to 3 parts of potassium stearate, 3 to 4 parts of polyethylene wax, 18 to 20 parts of dioctyl phthalate, 3 to 5 parts of zinc oxide, 1 to 2 parts of accelerant M, 0.5 to 1.0 part of bis(isooctylmercaptoacetate) dioctyldilauryltin, 12 to 15 parts of attapulgite, 12 to 15 parts of nano silicon dioxide and 14 to 16 parts of auxiliary agent. The prepared cable sheath material is high in strength and good in flexibility, and has the performances of high-temperature aging resistance, oil osmosis resistance and chemical solvent resistance by combining the advantages of SG-1 polyvinyl chloride, the POE, the low-density polyethylene and the other raw materials. Thus, the prepared cable sheath material can be widely used for preparing various cable sheath insulating materials, thereby having broad market demand prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to an oil-resistant and anti-aging modified polyvinyl chloride cable sheath material 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 saf...

[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.
