Oil-resistant and temperature-resistant PET cable sheath material with low cost

Abstract

The invention relates to a cable material and particularly relates to an oil-resistant and temperature-resistant PET cable sheath material with low cost. The material is prepared from the following raw materials in parts by weight: 30-34 parts of waste PET bottle particles, 23-25 parts of polyvinylidene fluoride, 12-15 parts of EVA, 2-3 parts of a calcium and zinc compound stabilizer, 1-3 parts of ammonium molybdate, 4-5 parts of copper oxide, 3-4 parts of iron sesquioxide, 2-3 parts of sodium hexametaphosphate, 1-2 parts of 10-hydyroxyl-2-caproleic acid, 16-18 parts of acetyl tri-n-butyl citrate, 12-13 parts of epoxy ethylhexyl stearate, 3-6 parts of calcium sulfate, 30-40 parts of N330 carbon black, 5-6 parts of antimonous oxide and 14-16 parts of an assistant. The insulating material combines the advantages of raw materials such as PET, polyvinylidene fluoride and EVA. The prepared material is high in strength, good in mechanical performance, can resist oil and chemical corrosion, can resist high temperature and low temperature aging, can resist oxidization and ray radiation and has a long service life. PET in the formula is a recycled waste, so that the production cost is effectively lowered, and the material has an extremely huge market popularization and application value.

Description

technical field [0001] The invention relates to a cable material, in particular to a low-cost oil-resistant and temperature-resistant PET 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.
