Abstract

The invention discloses a preparation method of an improved low-smoke halogen-free cable rubber jacket. The preparation method includes following steps: A, using EPDM rubber, methyl vinyl silicon rubber, 1, 3-acetone dicarboxylic acid diethyl ester, tetrabutyl ammonium hydrogen phosphate, dimethyl urea, m-caborane, 3-methoxy benzene methanol, 3-nitro-4-aminophenol, calcium sulfate, carbon black and zirconium oxide to preparing a cable inner jacket; B, using polyethylene, EVA rersin, EDTA, dicumyl peroxide, triethanolamine, tertbutyl isosulfate, 3-nitro-4-methyl acetophenone, potassium hydrogen sulfate, dibutyl fumarate and benzoyl acetonitrile to prepare a cable outer jacket; C, socketing the cable inner jacket prepared in the step A and the cable outer jacket prepared in the step B, and filling a flame retardant between the cable inner jacket and the cable outer jacket. By the preparation method, the defects of the prior art can be overcome, and mechanical performance of cables is improved further.

Description

technical field [0001] The invention relates to the technical field of cable fire prevention, in particular to an improved low-smoke halogen-free cable rubber sleeve and a preparation method thereof. Background technique [0002] With the rapid development of the global economy and the enhancement of human awareness of environmental protection, the requirements for the quality and performance of wires and cables in various fields are getting higher and higher, and there are more and more fires caused by the aging of wires and cables. How to reduce the fire Low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or magnesium hydroxide to polyolefin subst...
