Problems solved by technology
However, the polarity of fluorosilicone and silicone rubber is very different, and direct bonding cannot achieve a satisfactory bonding effect.
In addition, when the hose is used at high temperature, it is easy to cause the inner layer of fluorosilicone to fall off due to adhesion failure.

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings.
[0018] Depend on Figure 1-4 It can be seen that a composite oil-resistant rubber hose includes a mandrel 1, an inner layer of fluorosilicone rubber 2, an intermediate layer of fluorosilicone tape 3, an intermediate layer 4 of fluorosilicone tape, and an outer layer 5 of silicone rubber compound. The mandrel 1 is wound with vulcanizing agent Fluorosilica gel inner layer 2, on which the vulcanizing agent is added and the middle layer 3 of the silicone tape with a certain distance is wound, and the middle layer 4 of the fluorosilicone tape with the vulcanizing agent added is wound on the middle layer 3 of the silica gel tape. The middle layer 4 of the silicone belt is not completely overlapped with the middle layer 3 of the silicone belt, wherein an outer layer 5 of silicone rubber compounded with a vulcanizing agent is wound on the middle layer 4 of the fluorosilicone b...

Abstract
The invention relates to a composite oil-resistant rubber tube. The composite oil-resistant rubber tube comprises a core rod, a fluorosilicone rubber inner layer, a silicone rubber strip intermediatelayer, a fluorosilicone rubber strip intermediate layer and a silicone rubber mixed rubber outer layer, the core rod is wound with the fluorosilicone rubber inner layer with an added vulcanizing agent, the fluorosilicone rubber inner layer is wound with the silicone rubber strip intermediate layer with an added vulcanizing agent, the silicone rubber strip intermediate layer is wound with the fluorosilicone rubber strip intermediate layer with an added vulcanizing agent, the fluorosilicone rubber strip intermediate layer and the silicone rubber strip intermediate layer are not completely overlapped, and the fluorosilicone rubber strip intermediate layer is wound with the silicone rubber mixed rubber outer layer with an added vulcanizing agent. The composite oil-resistant rubber tube is simple in structure and reasonable in design, the oil-resistant rubber tube can be prepared by using silicone rubber and fluorosilicone rubber compound of any types, raw materials are not limited, and thefluorosilicone rubber layer and the silicone rubber layer are firmly compounded and cannot fall off permanently, and are particularly suitable for products such as a high-temperature oil-resistant pipe, a turbocharging pipe, a supercharged air outlet pipe and the like.
Description
technical field [0001] The invention relates to a composite oil-resistant rubber hose, which belongs to the technical field of automobile rubber hoses. Background technique [0002] Fluorosilicone rubber is a special type of silicone rubber. In addition to high and low temperature resistance, high resilience, weather resistance, easy processing, insulation, low surface energy and physiological inertness, it also has oil resistance, acid and alkali resistance and aromatic hydrocarbon resistance. Solvent and other advantages, it is currently the only elastomer material that can be used for a long time in the fuel environment of -60-210 ℃, and is widely used in aerospace, automobile and military industries. In recent years, fluorosilicone has been used as the inner lining material of turbocharger tubes, and turbocharger tubes with inner fluorosilicone and outer silicone are used in well-known car brands such as Mercedes-Benz and BMW. [0003] However, due to the high price of ...
