Waterproof flame-retardant cable material and preparation method thereof

Abstract

The invention discloses a waterproof flame-retardant cable material. The waterproof flame-retardant cable material is prepared from the following raw materials by weight: 30 to 60 parts of tetrafluoroethylene-propylene rubber, 25 to 40 parts of EPDM, 20 to 35 parts of chlorinated polyethylene, 10 to 30 parts of ammonium polyphosphate, 10 to 20 parts of kaolin, 20 to 30 parts of nanometer carbon black, 1 to 5 parts of sulfur, 15 to 30 parts of a fire retardant, 1 to 5 parts of an anti-oxidant and 1 to 5 parts of a lubricant. The invention also discloses a preparation method for the waterproof flame-retardant cable material. The preparation method is simple and is easy to operate. The prepared waterproof flame-retardant cable material has the characteristics of water resistance, damp resistance, flame retardation, aging resistance and the like, appears to be smooth and fine, can adapt to specific application environment condition and has broad market application prospects.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a waterproof and flame-retardant cable material and a preparation method thereof. Background technique [0002] With the development of the economy, the demand market for cables is broad, which promotes the progress of the production technology of cable materials. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, tensile strength, service temperature, and flame retardancy. There are strict requirements on performance and other indicators. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have poor flame retardancy, high temperature deformation, poor mechanical properties, poor waterproof performance, and long service life. Short and other problems bring a lot of inconvenience to the actual use, an...

Problems solved by technology

[0002] With the development of the economy, the demand market for cables is broad, which promotes the progress of the production technology of cable materials. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, tensile strength, service temperature, and flame retardancy. There are strict requirements on performance and other indicators. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have poor flame retardancy, high temperature deformation, poor mechanical properties, poor waterproof performance, and long service life. Short and other problems bring a lot of inconvenience to actual use, and even threaten the safety of people's lives and property. Therefore, it is urgent to change the original cable material formula and improve material performance to meet the diverse needs of the cable market.
