Abstract

The invention discloses an extrusion production, the fluorine rubber inner layer (1), resistance oil silicone rubber middle (2), kevlar line (3) and the outer layer of silicone rubber (4) composed of automobile turbocharged hose, broke the previous three-layer structure of the turbocharged, four- layer structure used, and uses advanced extrusion technology, braided hose to a molding process, the turbocharged hose reached appearance no impurities, without defects, flat and smooth. Not only increase production efficiency, but also through our compound formula, the structure of several aspects of research and development, so that the hose can meet the performance requirements of use, the hose improve the oil resistance, high temperature resistant, resistant infiltration, and improve the bursting pressure, the hose of the service life is extension.

Description

technical field [0001] The invention relates to the technical field of automobile turbocharger hoses, in particular to a fluorine rubber and oil-resistant silicone rubber, a silicone rubber turbocharger hose and a preparation method thereof. Background technique [0002] As automobile emission standards become more and more stringent, automobile manufacturers must not only meet environmental protection requirements, but also meet customer needs and ensure sufficient driving pleasure. Turbochargers do just that to lower emissions and improve fuel economy without sacrificing driving pleasure. Turbochargers provide better fuel economy because the boost delivers more air to the combustion chambers, resulting in more complete combustion and cleaner emissions. In Europe, turbochargers have accounted for 50%, and in Asia and the United States are also growing. Turbochargers have become the mainstream direction for improving power performance. This...
