Abstract

The invention provides a low temperature-resistant cable sheath material and a preparation method thereof. The low temperature-resistant cable sheath material comprises the following raw materials inparts by weight: 90-110 parts of an ethylene-vinyl acetate copolymer, 20-40 parts of bisphenol A-type polyarylate, 1-5 parts of polyphenylene sulfide fiber, 5-15 parts of calcium oxide, 5-15 parts ofparaffin oil, 0.2-0.6 part of diisononyl phthalate, 0.1-0.3 part of terephthalate and 0.05-0.15 part of a light stabilizer. The preparation method comprises the following steps: S1, preparing raw materials; S2, premixing the polyphenylene sulfide fiber, the calcium oxide and the paraffin oil; S3, mixing; S4, extruding, moulding and drying. The cable sheath material provided by the invention is reasonable in formula, low in temperature resistance and wear resistance, good in aging resistance and long in service life, the raw materials and the preparation process are environment-friendly, the preparation method is simple, reproducibility between batches is good, and the suitability for industrial production is achieved.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a low temperature resistant cable sheath material and a preparation method thereof. Background technique [0002] Cable is a general term for items such as optical cables and cables. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, power transmission, etc. It is a common and indispensable thing in daily life. In order to improve the service life and safety performance of the cable, a protective sheath is usually provided on the outside of the cable. Currently, commonly used materials for the cable sheath include rubber, polyethylene, and the like. Rubber cable sheaths have good elasticity, but poor anti-aging performance, and are prone to cracking when exposed to sunlight, which shortens the service life of cables. However, the anti-aging properties of polyethylene cable sheaths currently used P...
