Weatherable toughened modified polyethylene cable sheath material

Abstract

The invention relates to a cable material, and specifically relates to a weatherable toughened modified polyethylene cable sheath material. the material comprises the following raw materials in parts by weight: 15-19 parts of SG-2 PVC resin, 23-25 parts of POE, 24-28 parts of low-density polyethylene, 14-18 parts of calcined potter's clay, 1-2 parts of silver nitrate, 3-4 parts of sodium chloride, 2-3 parts of silane coupling agnet KH-550, 1-2 parts of zirconium fluoride, 6-8 parts of nanometer titanium dioxide, 2-3 parts of nanometer titanium phosphate, 8-10 parts of dimethyl isooctyl thioglycolate tin, 1-2 parts of anti-aging agent 4010, 12-15 parts of diatomite powder, 2-3 parts of ammonium polyphosphate, 25-30 parts of tributyl citrate and 14-16 parts of an auxiliary agent. The insulating material combines the advantages of low-density polyethylene, POE, PVC resin and the like, the prepared material is good in rigidity, high in toughness, good in mechanical properties, resistant to environmental aging, resistant to heat, resistant to flame, and safe and reliable to use, is widely applicable to preparation of various cable sheath insulating materials, and has wide market demanding prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to a weather-resistant and toughened modified polyethylene 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 safety,...

[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.
