Automotive rubber products to large-scale development of specialized high-performance

The automobile industry has been a major market for rubber products. General Motors rubber tires in addition to means other than a variety of rubber products, including a variety of hose, belt (V belt, timing belt), sealing products (oil seal, seal, the ring pad, etc.), rubber shock absorption and safety Products. A car with the rubber parts are 100 to 200 to Santana sedan, for example, the quality of its rubber products amounted to 66 kilograms, or nearly rubber 20 kg. As the world automobile production and sales volume to maintain the continued growth in non-tire rubber used in automotive rubber products, plastic consumption volume has been on top of the list. In the car in a big country, 90% and 70% of the damping rubber hose are used in the automotive industry. Such as Japan in 2004 on sales of automotive rubber products, rubber General Motors accounted for 35% of sales; 2004 U.S. auto sales accounted for rubber when U.S. sales of industrial rubber products of 37.6 percent. The two countries have annual production of automotive 10,000,000 or so, about a million vehicles need to use the car rubber 500,000,000 U.S. dollars. This shows that the automotive rubber in the rubber industry occupies an important position. In recent years, foreign automotive rubber products and the development of the main features of the movement are:

To achieve universal high-performance and high functionality of

At present, companies are actively developing new models required for the development of a new type of rubber and seek to improve the performance of existing products. If the vehicle V belt, is now using hydrogenated acrylonitrile-butadiene rubber manufacturing; in the automotive rubber shock absorption, high-function liquid-filled engine and the pad sleeve, Elastomer rubber seal so fluid, the shock occurred when the rubber spring Deformation, which has played the role of a buffer; the early 1980s, the United States successfully developed oil-filled PTFE composite materials, the successful resolution of the engine oil leakage problem, at the same time greatly improved the performance of automotive technology.

New materials development and application of rapid progress

Special rubber such as fluorine rubber in the car on the popularization and application, making it a vehicle in recent years the use of special rubber consumption in the fastest-growing types of plastic. Fluorine rubber in the automobile industry the main engine for the stem seal, cylinder seals, sealing the clutch, fuel pumps and fuel sealed plastic inner tube, and so on; HNBR heat-resistant, oil-performance, anti-aging resistance and a variety of media , Is a new generation of nitrile rubber products in high-performance auto parts in an increasingly wide range of applications, mainly used as a vehicle by the end of rubber timing belt, high-performance V at the end of rubber band, a variety of automotive rubber inner tube, contact seals, such as fuel ; Acrylate rubber prices are more moderate, heat the oil and heat aging performance, the auto industry in recent years become a focus on promoting the development of a sealing material mainly used for high-temperature oil, hydraulic shock absorber unit and hose; In the 1990s, energy saving and environmental protection of foreign auto thermoplastic elastomer (TPE) increase in the amount of material quickly, with some of the original neoprene, EPDM rubber-made parts have been or are being diverted to TPE manufacturing.

Process equipment innovation to make new progress

Rubber mixing rubber processing is the most basic technology, is currently a small number of large-scale automotive rubber rubber mixing plant have reached a more advanced system large-scale and intelligent, but the vast majority of small and medium-sized enterprises can not configure a large rubber mixing a high degree of automation equipment, for which foreign Has formed a special production of a variety of rubber, rubber-CMB's manufacturing industries; pressure forming a typical integration process is automatic tube production line in order to gain control of the computer LPC process, the solution for many years the existence of the wall thickness Uneven, eccentric and the size of the phenomenon of the first. Some also adopted CAD ~ CAM, so that further high-pressure hose in a row of vulcanization; model in the production of products, to meet the needs of high-temperature rapid curing, automatic vacuum plate curing, injection molding machines sulfide has been widely used.

The expansion of production scale and improve the professionalism

Rubber foreign auto parts enterprises increasingly expand production scale, have a strong scientific research strength, and a high degree of specialization, advanced production technology and equipment and a high degree of automation of the management system and therefore high productivity. Japan in the East China Sea, such as rubber is a vehicle to the production of rubber-based companies, in the United States and the building of a damping rubber hose factory, with annual sales of 2 billion U.S. dollars, only 1,000 employees, per capita sales 200,000 U.S. dollars more than similar companies in China to ten times higher.
