Anti-ageing fire-retarding modified polyolefin elastomer cable sheath material

Abstract

The invention relates to a cable material, and particularly relates to an anti-ageing fire-retarding modified polyolefin elastomer cable sheath material. The material is prepared from the following raw materials in parts by weight: 24-28 parts of a polyolefin elastomer, 18-22 parts of polyvinyl chloride, 12-15 parts of diatomite, 8-10 parts of kaolin, 1-2 parts of chloroplatinic acid, 0.1-0.2 part of cerium oxide, 0.2-0.4 part of lanthanum oxide, 2-3 parts of bismuth trioxide, 2-3 parts of dipentaerythritol hexaacrylate, 15-20 parts of tributyl citrate, 8-10 parts of petroleum resin, 15-20 parts of aluminium hydroxide, 1-2 parts of an accelerant TMTD, 3-4 parts of diaminodiphenylmethane and 14-16 parts of an additive. The insulating material is combined with the advantages of the raw materials including the polyolefin elastomer, polyvinyl chloride and the like, so that the prepared material is firm, wear-resisting, high temperature and low temperature ageing-resisting, chemical corrosion-resisting, good in low-temperature toughness, safe in fire retardance, long in service life, widely used for manufacturing various cable sheath insulating materials, and wide in market requirement prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to an aging-resistant flame-retardant modified polyolefin elastomer 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 propert...

[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.
