Problems solved by technology

The existing wire and cable sheath materials are mostly made of synthetic rubber. Although the synthetic rubber sheath has excellent physical and mechanical properties, acid and alkali resistance, high and low temperature resistance, etc., for the sheath used in oil wells, good oil resistance is required. However, the current sheath made of synthetic rubber has poor flex resistance and cannot meet the increasing market demand.

Abstract

The invention discloses an oil-proof rubber sheathing material for a cable and a preparation method thereof. The oil-proof rubber sheathing material for the cable is prepared from, by weight, 50-70 parts of chloroprene rubber, 20-40 parts of chlorosulfonated polyethylene, 10-15 parts of nitrile rubber, 3-5 parts of magnesium oxide, 2-4 parts of zinc stearate, 10-15 parts of ammonium polyphosphate, 5-10 parts of boron nitride, 3-4 parts of anti-aging agent, 8-12 parts of nano-magnesium hydroxide, 11-15 parts of nano-titanium dioxide, 15-20 parts of fumed colloidal silica dispersion, 2-3 parts of sodium benzoate, 10-15 parts of glycidyl methacrylate, 5-10 parts of dicapryl phthalate, 3-4 parts of accelerant and 3-5 parts of composite filler. The oil-proof rubber sheathing material has excellent heat resistance, wear resistance, aging resistance, ultraviolet radiation resistance, oil resistance, acid and alkali resistance and the like. Meanwhile, the oil-proof rubber sheathing material for the cable is durable in use.

Description

Technical field [0001] The invention relates to the field of cable sheaths, in particular to an oil-resistant rubber sheath material for cables and a preparation method thereof. Background technique [0002] The cable sheath is an indispensable middle structural part of the cable. It protects the cable, ensures the safety of the cable, and isolates the copper wire from water, air and other media to avoid leakage. The existing wire and cable sheathing materials are mostly made of synthetic rubber. Although the synthetic rubber sheath has excellent physical and mechanical properties, acid and alkali resistance, high and low temperature resistance, etc., the sheath used in oil wells needs good oil resistance. However, the current sheath made of synthetic rubber has poor flexural resistance and cannot meet the increasing market demand. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an oil-resistant rubber sheath material fo...
