[0048] First, as a halogen-based rubber without reactive functional groups, chloroprene rubber (CR) or chlorinated polyethylene (CPE) is used, and as a halogen-based rubber with reactive functional groups, chloroprene rubber (CR) is grafted. 3% glycidyl methacrylate reactive functional group CR-A, chloroprene rubber (CR) grafted 1% maleic anhydride reactive functional group CR-B, chlorinated polyethylene (CPE) grafted 3% glycidyl methacrylate reactive functional group CPE.

[0049] In addition, the modified PTFE is produced by the following method.

[0050] The PTFE7AJ (Mitsui Fluorochemicals) powder was heat-treated in the air at 360°C for 60 minutes, and the melting point was adjusted (about 328°C) to remove unstable crystals. While heating it in a heating furnace with an oxygen concentration of 0.5 Torr (66.65 Pa) a...

Abstract

The invention aims at tackling a problem of providing a halogen composition which has excellent low friction and excellent tensile property in a sliding environment and has high abrasion resistance, and a wire and a cable using the same. The method of solving the problem is providing a halogen composition which is acquired by the following steps: a halogen rubber which does not have a reactive functional group and a halogen rubber which is formed by a halogen rubber grafting reaction functional group and thus has a reactive functional group are taken for cooperation in mass ratio above 95 / 5 yet below 80 / 20, and with respect to the halogen rubber which does not have the reactive functional group and the halogen rubber having the reactive functional group, a modified PTFE is added above 5 and below 20 mass fractions, and further an amines above 0.1 yet below 2 mss fractions is added.

Description

Technical field [0001] The present invention relates to a halogen-based composition excellent in low friction properties in a sliding environment, and electric wires and cables using the halogen-based composition. Background technique [0002] Wires and cables are passed through or dragged around in conduits, pipes, etc. during wiring and laying. In addition, sometimes the wires and cables are in contact with each other or with other parts during use, so that they are slid for use. Therefore, it goes without saying that the coating materials of electric wires and cables are excellent in abrasion resistance, and low friction properties with good lubricity are also required. [0003] As a method to improve the situation, the coating material is usually mixed with solid lubricants such as graphite, molybdenum disulfide, tetrafluoroethylene resin (PTFE), silicone resin, lubricants, etc., but it may cause mechanical strength such as tensile strength. Significantly reduce such shortcom...
