Abstract

The invention discloses a rubber material, and a preparation method and a use thereof. The rubber material comprises natural rubber, butadiene rubber, a diaryl secondary amine antioxidant, a dihydroquinoline antioxidant, a physical antioxidant, an activator zinc oxide, stearic acid, a silane coupling agent, carbon black, sulfur, 4,4'-dithiodimorpholine, tetramethylthiuram disulfide, N-cyclohexyl-2-benzothiazole sulfenamide and an anti-scorching agent. The rubber material has the advantages of low damping coefficient, good mechanical strength, good elastic ductility and satisfactory temperature resistance. The preparation method of the rubber material has the advantages of simple steps, convenience in operation, and suitableness for industrial production. An exhaust system cold end hanger made of the rubber material has the advantages of large pulling strength, long service life, wide vibration isolation frequency, and excellent NVH control efficiency in the acceleration stage in the high speed (90 km / h or more) driving process of an automobile.

Description

technical field

[0001] The invention specifically relates to a rubber material, its preparation method and application. Background technique

[0002] Exhaust system is one of the important components of modern automobiles, which plays an important role in purifying exhaust emissions and absorbing engine exhaust excitation noise. As a load-bearing and vibration-isolation component of the exhaust system, the lifting lug suspends the exhaust system and isolates the transmission of vibration excitation from it to the body. The basic properties of the lifting lug include: reasonable dynamic and static stiffness; high enough breaking force and service life; sufficient temperature range. The manufacturing materials of the lifting lugs are mostly silicone rubber and EPDM rubber. Silicone rubber has a silicon-oxygen chain structure and has extremely high and low temperature resistance. The working temperature range is -60 to 300°C, and it is especially suitable for the high tempera...
