Abstract

The invention provides a rubber material, a cooling rubber pipe prepared from the rubber material and an automobile engine comprising the cooling rubber pipe, which relate to the technical field of automobile fuel systems. The rubber material is mainly prepared from ethylene propylene diene monomer, ethylene propylene diene monomer, mineral powder and a coupling agent according to specific component contents. The ethylene propylene diene monomer and the ethylene propylene diene monomer which have good heat resistance and aging resistance are creatively matched and used according to a specificratio, so that the prepared rubber material has good high-temperature resistance and chapping resistance; meanwhile, the mineral substance powder is added, so that the mechanical strength and the extrusion fluidity of the rubber material are improved; in addition, the invention also comprises a coupling agent, and the coupling agent can connect the ethylene propylene diene monomer with the mineralsubstance powder in a chemical manner, so that the resistance effect is better achieved. Therefore, the performance of the existing rubber material is optimized by selecting the raw materials of thecomponents and compounding the contents of the components.

Description

Technical field [0001] The present invention relates to the technical field of automobile fuel system, in particular to a rubber compound, a cooling hose prepared therefrom, and an automobile engine containing the cooling hose. Background technique [0002] Nowadays, the design of automobile engines tends to be small and light. However, this design tendency directly leads to an increase in the temperature in the engine compartment of the automobile, and at the same time, the reduction in the size of the engine and the more compact space bring about problems such as heat concentration in the engine compartment and difficulty in dissipating heat. [0003] Automobile cooling system pipelines are distributed in various positions of the engine compartment, and the closer to the engine, the higher the temperature. However, the existing radiator pipes and heater pipes made of traditional EPDM rubber are prone to cracking and aging risks under excessively high ambient temperature. The ex...
