Classification of automotive rubber products and their role in automobiles:

The rapid development of China's automobile industry has promoted the development of other related supporting industries in China, especially the rubber industry. In the past few years, automotive rubber products have developed into a unique specialized product industry. Automotive rubber products are an indispensable component in automotive accessories. There are about 100-200 rubber products installed in each car, and about 200-500 rubber parts are used. In addition to tires, depending on the size of the car, the consumption of rubber materials is about 15-60 kg, while automotive rubber products (excluding tires) account for about 6% of the total cost of the car. There are more than 1,000 varieties of non-tire rubber products for the automotive industry, with specifications exceeding 8,000. According to statistics, the automotive industry accounts for more than 70% of the world's annual consumption of raw rubber, of which 60% of tires and 40% of automotive rubber parts.

High speed, safety, comfort, energy saving and environmental protection are the goals pursued by contemporary cars. With the development of automobile modernization, the requirements for automotive rubber products are becoming increasingly strict and demanding. Not only rubber materials with various special properties are required to meet the new technical requirements of automobiles, but also rubber materials have higher physical and mechanical properties, such as Anti-aging, high temperature resistance, low temperature resistance, new fuel resistance, excellent dynamic fatigue performance, and durable service life. In fact, every high-performance of modern cars relies on the technological advancement of rubber products. The performance and quality of automotive rubber products play an important role in improving the quality of complete vehicles. It is worth pointing out that the role played by rubber products is always an accessory, but this accessory always keeps abreast of the technical progress and technical level of the mainframe. Therefore, it can be said that the technology and quality of automotive rubber products can basically reflect the technical level of automobile.

Rubber tires are called the two legs of a car, and the important role of the tire in the car is self-evident. Tires are rubber products with the largest amount of glue in the rubber industry, so in the rubber industry, tires are often separated from rubber products into a special type. In automotive parts, rubber tires are a special accessory.

Automotive rubber products can be divided into seven categories: tires, sealing products, shock absorbing products, safety products, tape products, hose products and other products such as wipers, fenders, adhesives, sealants and interior products.

1. Tire

• Car tires play the role of carrying the weight of the car, the weight of the people and the goods on the car, and also play the role of the car to advance, retreat, turn and brake. The safety, comfort and driving performance of a car depend to a large extent on the high performance and quality of the tire.
• Rubber tires have a history of 160 years. As early as 1845, the British R. W. Thomso put a hose on the wooden wheel, which reduced the rolling resistance of the wheel and reduced the vibration, but this early rubber tire was very popular at the time. Of course this should be attributed to the excellent properties of rubber materials. Until 1888, the British J. B. Dunlop invented pneumatic tires. In the next hundred years, with the development of the automobile industry, rubber tires have experienced the development and advancement of several generations of products. The development of tire frame materials from cotton cords, rayon to nylon cords To today's steel radial tires.
• Humans invented pneumatic tires, which effectively promoted the development of automobiles. Because the pneumatic tire has excellent shock absorption performance, the vibration is obviously reduced, the safety of the vehicle is better, the ride is more comfortable, and the driving speed of the vehicle can be greatly improved. With the continuous advancement of rubber materials, formulation technology, manufacturing equipment and manufacturing processes, the safety and durability of automobile tires are greatly improved. For example, in 1900, the mileage of each tire was only 800km; by 1978, the mileage of each tire had reached 60,000km; to the 21st century, the mileage of each tire was no less than 140,000km, or even 20 Ten thousand km. The speed of the car has increased significantly with the rapid construction and commissioning of the expressway, from tens of km/h to 100km/h, 140km/h and even 200km/h.

2. Sealing Products

• Sealing products are divided into three categories: O-rings, skeleton oil seals and sealing strips. O-rings and skeleton oil seals are installed in the engine, gearbox, car main shaft and hydraulic pneumatic transmission system to prevent leakage of lubricating oil, hydraulic oil and other liquids or gas leakage, to ensure the normal operation of various component systems, and to prevent external grit Dust impurities enter the system and affect the normal operation of the machine. O-ring seals and skeleton oil seals are primarily used for the sealing of rotating shafts or reciprocating shaft systems. According to the structure, the skeleton oil seal can be divided into internal skeleton oil seal, outer skeleton oil seal, semi-exposed skeleton oil seal, lip seal oil seal, with lip oil seal and combined oil seal, etc.; according to the installation position in the automobile, it can be divided into crankshaft front oil seal and crankshaft rear oil seal. , gearbox oil seal, cam box oil seal, wheel housing oil seal, semi-shaft oil seal, pneumatic guide oil seal and shock absorber oil seal. Sealant strips are mainly used in automobile doors and windows, trunks, engine covers, etc., and serve as sealing, windshield, rain, shock absorption and sound insulation. According to the structure, it can be divided into pure rubber sealing strip (also can be divided into sponge rubber and dense rubber) and composite sealing strip (divided rubber/metal skeleton composite strip, two or more rubber composite strips and rubber plastic composite strip).

3. Shock Absorption Products

• Rubber shock absorbers are mainly installed in engines, body, air conditioning and car suspension systems. It is mainly used to reduce the vibration and noise when the car is running, and to improve the stability, safety and comfort of the car. With the continuous improvement of the comprehensive performance of modern automobiles, higher and higher requirements are placed on the performance and quality of rubber shock absorbing products. Mainly required to have shock absorbing damping properties, anti-dynamic fatigue performance and long life durability. Automotive rubber shock absorbers mainly include air springs, engine front and rear suspension pads, flexible couplings, rubber bushings of various shapes, gaskets, and the like. In the premium car, special shock absorbers with excellent performance are also installed in each tire support.

4. Safety Products

• Automotive rubber safety products play a role in braking reliability, driving safety and personal safety in automobiles. Safety products mainly include brake film (diaphragm), cups, brake pads, airbags and bumpers.
• The brake film and the cup are directly related to the safety of the car. When an accident occurs in the car, the car is quickly decelerated and stopped to ensure the safety of the vehicle and personnel. Airbags are rubber products that provide safety for vehicle personnel in the event of an accident in the vehicle. The bumper is used to reduce the impact of a car in the event of a collision.

5. Hose Products

• Hose products are used in three parts of the chassis, engine and body.
