The tire oil consumption accounts for 20% to 30% of the vehicle's fuel consumption, which is an important part of the low-carbon and energy-saving of the automotive industry. Relying on technological progress, the use of new materials, new processes, and new formulas to further reduce tire rolling resistance and achieve green tires have become a major goal for the tire industry in the future. This is the information that the reporter obtained from the Green Concept, Low-Carbon Economy, 2010 China Tire Technology Forum held by the Tire Branch of the China Rubber Industry Association on July 7-8, 2010.
Fan Rende, head of the China National Rubber Association, said that fuel-efficient, environmentally-friendly and safe tires have become the mainstream trend in the development of automotive tires. Although China is the world's largest tire producer, there is still a gap in technology compared with the world-famous tire companies. Product homogenization is still common. In particular, the European Union, the United States, and Japan all impose stricter regulations on the fuel efficiency of tires, which means that higher standards are imposed on tire performance. China's tire companies can only meet this requirement by developing low-rolling-resistance energy-saving and environmentally-friendly tires.
According to Cai Weimin, secretary general of the tire division, tire rolling resistance is reduced by 20%, fuel saving can be achieved by 2% to 4%, mileage of tires is increased by 35%, carbon dioxide emission is reduced by 4 grams per kilometer, and each vehicle can save 23 liters of fuel each year. . Under the premise of not changing the body, using only green tires will enable the car to achieve better emission reduction targets. Therefore, the greenization of the tire industry will certainly contribute to the development of China's low-carbon economy.
Cai Weimin believes that China's tire industry should integrate resources and cooperate extensively with production, teaching, and research to innovate from the source of product design: in terms of tire shape design and tread pattern development, improve design and improve product quality; in terms of new materials, strengthen natural rubber, Researches on gutta percha, synthetic rubbers and skeletal materials focus on the development and application of environmentally friendly, light weight, and recyclable materials. In terms of process technology and equipment, we must develop from stand-alone design and manufacturing to integrated linkage devices, especially to speed up testing. The R&D and manufacturing of equipment and the construction of tire testing grounds; the use of green additives to support the development and application of special materials such as carbon black and white carbon.
At present, major domestic tire companies have also realized the importance of low-carbon economy for enterprise development. For example, Hangzhou Zhongce Rubber Company has invested 80 million yuan in the development and manufacture of green tires last year; Triangle Tire Company proposes that green tire products will be developed in the next three years. More than 70%; South China Rubber Tire Co., Ltd., through a series of technological innovations, significantly reduced energy consumption; Fengshen Tire Co., Ltd. developed low rolling resistance tires to improve tire retreadability; Shuang Qiang Co., Ltd. actively developed all-steel radial tire nitrogen vulcanization. New technology and so on.
