Problems solved by technology

[0003] Currently on the market, the cable sheaths on the market tend to form burrs and cutting edges when the sheath is cut off. If they are not trimmed, the steel wire rope will rub against the burrs and cutting edges, resulting in abnormal noise and wear and tear when the wire rope penetrates into the wire rope. , if it is trimmed, the inner tube will be damaged to varying degrees, resulting in contact and friction between the steel wire rope and the metal part, resulting in product failure, especially the high failure rate of the throttle cable and lifter cable

Abstract

The invention relates to the technical field of inhaul cables, in particular to an inhaul cable sheath and a preparation method thereof. A sheath component is a section of half tube body which is provided with a draw pin and a mortise at two joint parts respectively. The inhaul cable sheath is characterized in that the sheath component is prepared from the following raw materials in parts by mass:10 to 20 parts of modified rubber, 6 to 12 parts of cyclodextrin, 5 to 8 parts of antioxidant, 3.6 to 6.4 parts of anti-ultraviolet agent, 1.2 to 3.6 parts of magnesium borate whisker, 1.2 to 3.6 parts of carbon nanofibres, 6 to 12 parts of vaseline, 2.4 to 4.8 parts of tourmaline particles, 1.6 to 3.2 parts of silicon carbide, 0.8 to 2.4 parts of diethylene glycol dibenzoate, 1.2 to 3 parts of nano titanium dioxide, 0.8 to 1.6 parts of calcium/zinc compound stabilizer, 1.2 to 5 parts of rare earth and 2.4 to 6 parts of flaky additives. The inhaul cable sheath disclosed by the invention has the advantages of good tensile strength, elongation and tensile modulus due to the use of the modified rubber; in addition, the proportion of raw materials is reasonable and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable sheath and a preparation method thereof. Background technique [0002] Car cables are divided into gear cables, clutch cables, and brake cables Definition: used to pull and change transmission gears, clutches, and brake wire ropes. Acting rod manipulation to change the speed or traction of machines such as machine tools, automobiles, tractors, cargo or door locks, consisting of many different diameters. Usually installed on the engine carburetor, fuel pump, throttle, transmission, clutch, wheel hub. [0003] Currently on the market, the cable sheaths on the market tend to form burrs and cutting edges when the sheath is cut off. If they are not trimmed, the steel wire rope will rub against the burrs and cutting edges, resulting in abnormal noise and wear and tear when the wire rope penetrates into the wire rope. , if it is trimmed, the inner tube will be damaged to varyin...
