Problems solved by technology

However, the high temperature aging resistance and ozone resistance of natural rubber are poor. The working environment temperature around the engine shock absorber cushion is generally -40-70°C. Some engine shock absorber cushions require high temperature resistance to reach 100°C. If the engine continues to work, In the high temperature environment, the elasticity of rubber products becomes poor and brittle, so that they cannot work normally during long-term high temperature use, and quality problems occur, which brings safety hazards during driving.

Abstract

The invention discloses a butadiene-acrylonitrile rubber material for automobile engine shock absorption and a preparation method thereof. The butadiene-acrylonitrile rubber material is prepared from the following raw materials: butadiene-acrylonitrile rubber, natural rubber, acrylate rubber, tricaprin, diethyl terephthalate, distearoyl isopropoxy aluminate, triallyl isocyanurate, methyl ethyloxy silicone oil, carbon fiber, acrylic pulp, diamond micro-powder, nano-zinc oxide, dibutyltin dilaurate, benzoylacetone, sulphur, 1,4-cyclohexanedimethanol, tetrahydrofurfuryk oleate, tin antimony oxide, potassium titanate whiskers, sepiolite fabric, and the like. According to the butadiene-acrylonitrile rubber material for automobile engine shock absorption and the preparation method thereof, the components are simple, and the preparation technology is simple; carbon fiber, potassium titanate whiskers, and the like, are added in the rubber, so that the shock resistant effect of the rubber is improved, the energy loss coefficient of the rubber is increased, and the rebound resilience is reduced; diethyl terephthalate, acrylic pulp, and the like, are added and matched, so that abrasion resistance of the rubber is improved, the dosage of a plasticizer is decreased, and properties such as flexibility of the rubber are improved.

Description

technical field [0001] The invention relates to a rubber material, in particular to an acrylonitrile-butadiene rubber material for shock absorption of an automobile engine and a preparation method thereof. Background technique [0002] The car engine is the engine that provides power for the car. It is the heart of the car and affects the power, economy and environmental protection of the car. According to different power sources, automotive engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids. Common gasoline engines and diesel engines are both reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy of piston movement and output power to the outside. [0003] The car engine is the main vibration source of the car. The transmission of engine vibration directly affects the reliability and service life of the vehicle, and also makes the driver's comfort worse and reduces ...
