Polystyrene electric cable sheath material with characteristics of light weight, water resistance and fire retardation

Abstract

The present invention relates to an electric cable material, particularly to a polystyrene electric cable sheath material with characteristics of light weight, water resistance and fire retardation, wherein the material comprises the following raw materials by weight: 15-18 parts of a phenol formaldehyde resin, 30-35 parts of polystyrene, 12-15 parts of polyvinyl acetate, 28-33 parts of fluorite powder, 4-5 parts of alumina, 1-2 parts of an antioxidant DSTP, 2-3 parts of propylene glycol, 5-8 parts of silica powder, 6-8 parts of ethylenebis(stearamide), 25-30 parts of epoxy butyl oleate, 10-12 parts of N351 carbon black, 1-2 parts of an anti-aging agent OD, 6-8 parts of dimethyl fumarate, 2-3 parts of triethoxyvinylsilane, 1-2 parts of ammonium dihydrogen phosphate, and 14-16 parts of an auxiliary agent. According to the present invention, the material integrates advantages of the phenol formaldehyde resin, polystyrene, polyvinyl acetate and other raw materials, the processing performance and the mechanical property are improved, and the prepared material has characteristics of light weight, good flexibility, water resistance, damp resistance, high temperature resistance, fire retardation, chemical reagent corrosion resistance, safety, durability and broad market requirement prospect, and can be widely used for production of various types of electric cable sheath insulating materials.

Description

technical field [0001] The invention relates to a cable material, in particular to a lightweight waterproof flame-retardant polystyrene 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, th...

[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.
