Ten years ago, few people in China would have imagined the number of cars and the congestion of roads in Beijing, Shanghai, Guangzhou and other cities. With the development of national economy and the continuous improvement of people's living standards, cars have entered ordinary families. Private car purchase has become the main growth point of automobile consumption, which promotes the rapid development of automobile industry as a pillar industry in China. According to statistics, in 2006, China's automobile production reached 6.94 million, an increase of 31.4% over 2005. In 2007, China's automobile production exceeded 8.88 million, an increase of 27.9% over 2006. Since 2003, China's automobile production has grown at an annual rate of more than 25%. China's automobile production has leaped from the third place in the world in 2006 to the second place. It has surpassed Japan, second only to the United States, and ranked second in the world. According to the prediction of the authoritative department of Beijing auto show in 2008, China's auto production is expected to reach 10 million in 2008. China has become a real big country of automobile production and consumption in the world.

Here are some important automobile rubber pipes, such as radiator rubber pipes. With the development of automobile towards energy saving and low pollution, the engine temperature has increased by 15 ~ 50 ℃ in recent years, so we also have higher requirements for automobile rubber pipes. Therefore, the radiator rubber pipes produced by sulfur curing system are gradually used in peroxide system They are replaced by the products they produce.
The main feature of this kind of hose is that it has good heat resistance. In foreign countries, the turbocharger hose is basically all rubber structure, that is, the inner rubber layer is composed of fluororubber and silicone rubber with good heat resistance, the reinforcing layer is composed of high-strength aramid fiber knitted fabric, and the outer rubber layer is made of silicone rubber, which makes the hose have stronger heat resistance Thermal performance.
Although a few manufacturers can produce fluororubber and acrylic oil seals, the output and quality can not keep up with the needs of the automotive industry, and its service life is less than 100000 km. The key parts of car oil seals, such as crankshaft rear oil seal and automobile guide rod oil seal, still rely on imported parts, so the localization rate is very low. For the framework oil seal, it is the future task to further improve the heat resistance, dynamic fatigue resistance and compression shrinkage deformation performance of the compound, improve the level of tooling and automation, and improve the accuracy of mold processing. The main material of oil seal will be widely used in fluorosilicone rubber, Chloroether rubber, hydrogenated nitrile rubber and acrylic rubber.
High speed, safety, comfort, energy saving and environmental protection are the goals of modern automobile. With the development of automobile technology, rubber products not only meet the requirements of more stringent physical and mechanical properties, but also have higher requirements of low-temperature durability. In fact, every high performance of modern automobile depends on the technical progress of rubber products to provide protection. The performance and quality of rubber products play a key role in improving the quality level of automobile. It is worth noting that the role of rubber products is accessories, but this accessory always affects the technical progress and level of the host. Therefore, it can be said that the technology and quality of automobile rubber products can basically reflect the technical level of automobile.
