Problems solved by technology

But like most hydrocarbon polymers, EPDM rubber is also very flammable, and the oxygen index of pure rubber is only about 19. In addition, the current cables generally have poor cold resistance and are prone to embrittlement.

Abstract

The invention discloses a cable material with high cold resistance and a preparation method thereof. The cable material is prepared from the following raw materials in parts by weight: 100 to 120 parts of Germany Lanxess EPDM rubber 9650, 20 to 30 parts of active chlorine type acrylate rubber AR-400, 10 to 15 parts of chloroprene rubber CR121, 10 to 15 parts of di-n-butyl nylon acid ester, 5 to 10 parts of trioctyl trimellitate, 5 to 10 parts of triethyl phosphate, 1 to 2 parts of sulfur, 2 to 4 parts of benzoperoxide, 1 to 2 parts of triallyl isocyanurate, etc. The cable material provided by the invention has the advantages of excellent flame retardance and nonflammability, good high-temperature and low-temperature resistance, corrosion resistance, water resistance, wear resistance, ozone resistance and aging resistance, and durability in use.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a high-cold-resistant cable material and a preparation method thereof. Background technique [0002] Since the advent of EPDM in 1962, due to its excellent ozone resistance, weathering resistance and heat aging resistance, as well as good electrical insulation, thermal deformation and chemical corrosion resistance, relative density It is small and has a large amount of filling, which is valued by the cable industry. At present, it has replaced traditional styrene-butadiene rubber, natural rubber and butyl rubber, and has been widely used in medium and high voltage cables for marine and mobile applications. However, like most hydrocarbon polymer compounds, EPDM rubber is also easy to burn, and the oxygen index of pure rubber is only about 19. In addition, the current cables generally have poor cold resistance and are easy to embrittle. Therefore, the development and development of...
