Abstract

The invention belongs to the field of cable materials, and particularly relates to a low-temperature-resistant cable material. The low-temperature-resistant cable material mainly comprises the following raw materials in parts by weight: 100 parts of EPDM (ethylene-propylene-diene monomer), 10-20 parts of reinforcing agent, 10-20 parts of cold-tolerance plasticizer, 40-60 parts of filler, 15-20 parts of high / low-temperature-resistant modifier, 2-4 parts of softener, 0.1-0.5 parts of ultraviolet light absorber, 0.1-0.5 part of anti-ageing agent, 1-3 parts of tert-butylperoxyisopropyl benzene, and 1-3 parts of triallyl cyanurate. The cable material disclosed by the invention is not cracked in low-temperature impact tests and bending tests at a temperature of minus 50 DEG C, so that the cable material meets the application of cables in low temperature environment; in addition, due to the used environmental-friendly auxiliary materials, the cable material can meet the environment-friendly requirements of ROHS (Restriction of Hazardous Substances) of the EU (European Union).

Description

technical field [0001] The invention belongs to the field of cable materials, and in particular relates to a low-temperature-resistant cable material and a preparation method thereof. Background technique [0002] In the extremely cold areas near the Arctic Circle and the Antarctic Circle, the temperature is very low (especially in winter) and the ultraviolet light is strong. The sheath and insulation of general tool wires and extension wires will crack at low temperatures, lose their protection for power transmission and fail. In addition, the ultraviolet light in the extremely cold areas around the Arctic Circle and the Antarctic Circle is strong, and ordinary organic polymer materials cannot withstand ultraviolet light aging and fail. Since the tool wire will be used outdoors and needs to be moved frequently, the flexibility of the cable is highly required, especially at extremely low temperatures, and the product is required to have good weather resistance. [0003] At ...
