Problems solved by technology

The turbocharger rubber hose is used to transport air and exhaust gas, and it usually has to withstand high temperatures above 180°C to play the role of connection, shock absorption, and noise reduction. Once damaged, the turbocharger will increase the speed and pressure ratio and cause the engine to work serious consequences
Since the high temperature resistant turbocharger is mainly made of silicone rubber, it has high technical content, difficult production and low efficiency, so it is not suitable for continuous extrusion process

Abstract

The invention discloses an ethylene-acrylic elastomer turbocharging rubber hose and a manufacturing method thereof. The ethylene-acrylic elastomer turbocharging rubber hose comprises a rubber hose body and is characterized in that the rubber hose body is composed of an inner fluororubber layer, a middle ethylene-acrylic elastomer layer, an aramid cord layer and an outer ethylene-acrylic elastomer layer; and the thickness of the inner fluororubber layer is 0.4mm-1.0mm, the thickness of the middle ethylene-acrylic elastomer layer is 1mm-4mm, the thickness of the aramid cord layer is 0.1mm-2mm, and the thickness of the outer ethylene-acrylic elastomer layer is 1mm-4mm. The ethylene-acrylic elastomer turbocharging rubber hose has the following beneficial effects that the fluororubber and ethylene-acrylic elastomer as well as ethylene-acrylic elastomer turbocharging rubber hose of the structure can meet the using requirements of being resistant to fuel oil, permeation and high temperatures, the bursting pressure is high, the using requirements of an automobile engine system can be met, and the adhesive force between the wall layers of the hose is higher than or equal to 3N / mm.

Description

technical field [0001] The invention relates to a turbocharger rubber hose and a manufacturing method thereof, in particular to an ethylene acrylate rubber turbocharger rubber hose and a manufacturing 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 70%, and in Asia and the United States are also growing. Turbochargers have become the mainstream direction for improving power performance. This means that the development and development of turbocharg...
