Abstract

The invention discloses a cable sheathing material containing modified dickite powder and a preparation method thereof. The cable sheathing material is prepared from the following raw materials in parts by weight: 50 to 60 parts of natural rubber, 20 to 30 parts of butadiene rubber, 10 to 15 parts of polybutylene terephthalate, 15 to 20 parts of stearic acid, 4 to 6 parts of chlorosulfonated polyethylene, 8 to 10 parts of p-tert-butyl-phenolic resin, 4 to 6 parts of microcrystalline wax, 3 to 6 parts of epoxidized soybean oil, 8 to 10 parts of anilmomethyl triethoxy silane, 5 to 7 parts of decabromodiphenyl ether, 1 to 3 parts of nanometer alumina, 3 to 5 parts of zinc borate, 3 to 5 parts of fumed white carbon black, 8 to 10 parts of bentonite, 8 to 12 parts of modified dickite powder, 4 to 7 parts of brucite powder and 3 to 6 parts of tree ash. The cable sheathing material provided by the invention has excellent low-temperature resistance with the lowest temperature reaching minus 65 DEG C on the basis of guaranteeing physical and mechanical performances and flame retardance of the sheathing material.

Description

technical field [0001] The invention relates to the technical field of cable sheathing, in particular to a cable sheathing material containing modified dickite powder and a preparation method thereof. Background technique [0002] The cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and isolating the copper wire from water, air and other media to avoid leakage. The existing wire and cable sheathing materials have low crack resistance, poor low temperature resistance, brittleness greatly affected by temperature, and poor frost resistance. Therefore, for special environments such as low temperature environments, the current cable sheaths cannot reliably meet the requirements of long-term use under low temperature conditions. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a cable sheat...
