Abstract

The invention discloses an anti-cracking high density polyethylene cable material and a preparation method thereof. The anti-cracking high density polyethylene cable material is prepared from the following raw materials in parts by weight: 50-70 parts of high density polyethylene, 20-30 parts of ethylene-vinyl acetate copolymer, 15-20 parts of ethylene-tetrafluoroethylene copolymer, 10-15 parts of methyl methacrylate-acrylonitrile-butadiene-styrene copolymer, 5-10 parts of ethylene-vinyl acetate copolymer graft maleic anhydride, 10-15 parts of magnesium hydroxide, 5-10 parts of red phosphorus, 4-6 parts of zinc borate, 3-5 parts of ethylene bis stearamide, 2-3 parts of calcium stearate, 10-15 parts of activated aluminum oxide, 2-4 parts of dicumyl peroxide, 1-2 parts of di-n-butyltin dilaurate, 15-20 parts of epoxidized soybean oil, 10-15 parts of nano wollastonite, 5-10 parts of coarse whiting powder, 4-8 parts of basic magnesium sulfate whisker, 1-2 parts of antioxidant 1035, 1-2 parts of antioxidant DSTP and 3-6 parts of compound filler. The cable material disclosed by the invention has excellent anti-cracking performance, good mechanical property, high / low-temperature resistance and bending property, can work for a long period of time in the working environment of -50 to 130 DEG C without cracking, can bear various bends, is durable and has broad application prospect.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a crack-resistant high-density polyethylene cable material and a preparation method thereof. Background technique [0002] In recent years, with the vigorous development of my country's telecommunications network, urban rail transit, railways, building construction and other projects, the demand for wires and cables has risen sharply, prompting a rapid increase in the use of cable materials. Although the performance of the cable material has been greatly improved with the continuous improvement of the material technology, the problem of easy cracking of the cable sheath that has been plaguing the industry has not been solved. The industry generally believes that the cable bending force and heat and cold are the causes of the above problems. In order to prevent the industry from being troubled by the problem of cable sheath cracking, it is necessary to develop a...
