It is reported that in 2009, China's total domestic automobile tire production reached 380 million, and in 2010 it is expected to reach 400 million, accounting for nearly one-third of the world's total production. Tires have a great impact on the energy consumption of automobiles. If the tires have the advantages of smaller rolling resistance, more wear resistance, and comfortable ride, the energy loss in China will be reduced, and our trips will also be more environmentally friendly. This type of tire will become a trend in the current tire industry.
The “green tires†featuring safety, high efficiency, energy saving and environmental protection are the mainstream of the international tire industry. "Green tire" adopts a new technology formula design, which has the advantages of good elasticity, low rolling resistance, low fuel consumption, low heat generation, wear resistance, puncture resistance, large carrying capacity, and comfortable ride. Compared with traditional tires, it highlights many advantages such as environmental protection, energy saving, new processes, and new materials.
Due to the addition of carcinogenic rubber compounding agents, traditional tires dissipate in the air as the tread wears and seriously pollute the environment. At the same time, hundreds of millions of tires are discarded each year in the world. They not only occupy a lot of space, but also are difficult to decompose. It poses a great threat to the environment and is known as "black pollution." With the continuous improvement of people's environmental awareness, while continuing to work hard to reduce rolling resistance, it has begun to attach importance to the use of environmentally friendly materials to manufacture tires, and efforts to extend the mileage of tires to reduce the number of used tires. After a large number of cars use green tires, they have a great effect on fuel economy and pollution reduction. The widespread use of green tires will save millions of barrels of oil each year and significantly reduce CO emissions.
Conventionally used black tires are made of standard synthetic rubber and natural rubber. Under the condition that the car driving temperature is increased, the structure and performance of the protective material are changed, and the resistance to wheel rolling is also increasing. Compared with ordinary tires, green tires reduce the weight of tires and reduce the energy consumption (hysteresis) of composites. Therefore, compared with tires of the same specifications, green tires can reduce rolling resistance by 22% to 35%, and thus reduce automobile fuel consumption by 3% to 8%, resulting in a reduction in automotive CO emissions, and other properties such as wear resistance. , low noise, grip on wet and dry roads, etc. are all maintained at a good level.
By optimizing the carcass design, green tires improve the car's grip on smooth roads with excellent elastic treads, making driving smoother, shorter braking distances, and greatly improving driving safety. Research shows that the friction generated by green tires can reduce the braking distance of 15% on wet or icy roads, and increase the winter driving performance of cars by 10%-15%. This has great significance in reducing accident rate and casualties.
Therefore, green tires with energy saving and low carbon will become the development trend of the future tires.
