Ageing resistant power line sheath material and preparation method thereof

Abstract

The invention discloses an ageing resistant power line sheath material and a preparation method thereof. The ageing resistant power line sheath material is prepared by using the following raw materials, by weight, 45-65 parts of ultrahigh molecular weight polyethylene, 25-35 parts of chloroprene rubber, 10-20 parts of polybutylene terephthalate, 1.5-2.5 parts of vinyltrimethoxy silane, 2-3 parts of dicumyl peroxide, 4-8 parts of basic magnesium carbonate, 22-28 parts of nanometer kaolin, 14-26 parts of glass bead, 3-6 parts of glyceryl monoricinoleate, 10-15 parts of nylon acid dibutyl ester, 8-16 parts of dicyclohexyl phthalate, 5-10 parts of phosphoric trichloride, polymer with 1,3-benzenediol, phenyl ester, 5-10 parts of tris(2,3-dibromopropyl)isocyanurate, 1-2 parts of dibasic lead phosphite, 1-2 parts of calcium stearate, 1-2 parts of barium stearate, 4-6 parts of paraffin oil, 0.5-1.5 parts of tetramethylthiuranm monosulide, 1-2 parts of 2-mercaptobenzothiazole and 20-25 part of an assistant. The sheath material has the characteristics of strong ageing resistance, good chemical stability, high mechanical strength, wide use temperature, excellent flame resistance, excellent impact resistance, excellent wear resistance, excellent chemical corrosion resistance, durability, and wide application prospect.

Description

technical field [0001] The invention relates to a power cord sheathing material and a preparation method thereof, in particular to an anti-aging power cord sheathing material and a preparation method thereof. Background technique [0002] The power cord is a wire that transmits current, and the sheath is an indispensable structural part of the power cord, which plays the role of protective insulation, ensures the safety of the power cord, isolates the conductor from water, air and other media, and avoids leakage. At present, the power cord sheath material on the market has the disadvantage of poor aging resistance, and it is prone to aging and cracking after long-term use, thus affecting the normal operation of the power cord. Therefore, be badly in need of developing a kind of anti-aging power cord sheathing material. Contents of the invention [0003] The object of the present invention is to provide an anti-aging power cord sheathing material and a preparation method t...
