Abstract

The invention relates to a cloth winding rubber hose compositely extruded by fluorubber and silastic, and a preparation method thereof; the turbo charging rubber hose made of the fluorubber, oil-proof silastic and cloth winding silica gel comprises a fluorubber inner layer 1, an oil-proof silica gel middle layer 2, and a silica gel cloth outer layer 3, wherein, the thickness of the inner layer is 0.4mm to 1.0mm, the thickness of the middle layer is 1mm to 3mm, and the thickness of each silica gel cloth is 0.5mm to 1.5mm. The preparation method of the invention comprises the following steps of the tube blank manufacturing operation, the reinforcement layer preparation, and the vulcanization and forming process. The invention adopts the silica gel cloth as the reinforcement layer instead of the previous aramid yarns, one layer of cloth winding can be carried out when the aramid yarns are adopted, a plurality of layers of cloth winding can be carried out according to the requirements when the silica gel cloth is adopted, and the rubber hose adopts the technology of firstly and compositely extruding the fluorubber and the oil-proof silica gel, then winding the silica gel aramid cloth, thus further improving the bursting pressure and long-term pulse performance of the turbo charging rubber hose of a heavy-duty vehicle, and prolonging the service life of the rubber hose used in the heavy-duty vehicle.

Description

technical field [0001] The invention relates to the technical field of turbocharged hoses for heavy-duty vehicles, in particular to a fluororubber-silicon-rubber compound-extruded cloth-wrapped hose and a preparation method thereof. Background technique [0002] Turbochargers are increasingly used in modern diesel engines, which can increase the power of diesel engines and improve economic performance. After the diesel engine uses a turbocharger, the engine has high power per liter, low fuel consumption, less pollution, and both indicated power and effective power are improved, which means that the mechanical efficiency is improved, and the economy of high-load operation can be obviously improved. The turbocharger increases not only the power range, but also the economical operating range at high loads. In the low load area, the turbocharger does not significantly improve the economy. [0003] This feature of the turbocharger is very beneficial for heavy-duty diesel vehicl...
