Oil-proof flame-retardant modified polyvinyl chloride cable sheathing material

Abstract

The invention relates to a cable material, and particularly relates to an oil-proof flame-retardant modified polyvinyl chloride cable sheathing material. The material comprises the following raw materials in parts by weight: 35-38 parts of SG-2 polyvinyl chloride, 12-14 parts of light calcium carbonate, 2-3 parts of stearic acid, 7-9 parts of titanium dioxide, 23-26 parts of chlorinated polyethylene, 12-14 parts of isotactic polypropylene, 6-9 parts of acrylonitrile butadiene styrene (ABS) high-glue powder, 7-9 parts of ethylene vinyl acetate (EVA), 14-18 parts of nano celestite powder, 1-2 parts of triethanolamine, 23-24 parts of castor oil, 1-2 parts of bisphenol A, 12-13 parts of semi-refined paraffin wax, and 14-16 parts of assistant. By adopting the insulated material, the advantages of the raw materials such as the SG-2 polyvinyl chloride, the chlorinated polyethylene, the isotactic polypropylene and the like are combined; the prepared material is high in strength, good in weathering resistance, ozone resistance, oil-resistant flame retardancy and chemical stability, safe to use, and wide in market demand prospect, and can be widely applied to fabrication of kinds of cable sheath insulated materials.

Description

Technical field [0001] The invention relates to a cable material, in particular to an oil-resistant flame-retardant modified polyvinyl chloride cable sheath material and a preparation method thereof. Background technique [0002] With the development of economy, the places that need to use cables have become diversified, and there are more stringent and diverse requirements on the performance indicators of cable sheath materials, such as insulation, tensile strength, use temperature, flame retardancy, etc. All have strict requirements. Continuously improving the performance of sheath materials is an urgent need for economic and social development. Traditional sheath materials have poor flame retardancy, poor chemical stability, high temperature deformation, poor mechanical properties, and short service life. Such problems have brought a lot of inconvenience to actual use, and even threatened people's life and property safety. Therefore, it is urgent to change the original sheath ...

Problems solved by technology

[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.
