Abstract
The invention discloses a modified ethylene-methyl acrylate-containing cable sheath material and a preparation method thereof. The modified ethylene-methyl acrylate-containing cable sheath material comprises modified ethylene-methyl acrylate, low-density polyethylene resin, precipitated silica, zirconia, ceramic powder, insoluble sulfur, an antiager RD, dicumyl peroxide, a rare earth stabilizer, 2,6-di-tert-butyl-4-methylphenol, dibutyl maleate and magnesium hydrate. The preparation method utilizes the modified ethylene-methyl acrylate as a main material. Through modification of ethylene-methyl acrylate, performances such as tensile strength, elongation at break, a tensile strength retention rate after aging, a breaking elongation retention rate after aging, and an impact brittle temperature are greatly improved. Zirconia and ceramic powder are used as fillers so that low smoke, no halogen, environmental protection and good safety are realized.
