Abstract

The invention discloses a cable material for an anti-fracture cable and a preparation method thereof. The cable material for the anti-fracture cable comprises, by weight, 40-50 parts of polyvinyl chloride resin, 8.5-10.5 parts of urea formaldehyde resin, 6-8 parts of EBST, 10-12 parts of dioctyl phthalate, 2.5-3.5 parts of sodium tripolyphosphate, 4-6 parts of melamine cyanurate, 10-12 parts of modified hard clay, 1.5-2.2 parts of modified fly ash, 7-9 parts of cracking resistant additive, 0.4-0.6 part of polyethylene wax, 0.4-0.6 part of zinc stearate and 1.5-2.5 parts of vulcanizing agent. The cable material is good in mechanical property and high in oil resistivity and chemical resistance, the compatibility and compactness of all the materials are enhanced by adding the cracking resistant additive and other auxiliaries, and the tearing strength, resilience force and the like of finished products are further improved.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to a cable material for anti-crack optical cables and a preparation method thereof. Background technique [0002] At present, the cable materials on the market have the disadvantages of easy breakage and low overall strength. Because polyolefin has the characteristics of low relative density, chemical resistance, good water resistance, good mechanical strength, electrical insulation, etc., polyolefin compositions with elasticity and good thermoplastic properties have been widely used in various fields. For example, it can be used in films, pipes, plates, various shaped products, wires and cables, etc. When polyolefins are used in wires and cables, the hardness of the cable material will increase, and it is not suitable for occasions where soft cables are required. Contents of the invention [0003] The object of the present invention is to provide a cable material for crack-resista...
