Plants are well-known rubber enterprises to follow up
In recent years, with the advancement of global tire R&D technology, the plant rubber materials such as ginko rubber, dandelion rubber, and gutta percha are invented, injecting new forces into the development of new tire materials in China.
According to experts, ginko is a xeric shrub that grows in the southwestern United States. At present, Bridgestone , Cooper and other internationally renowned tire companies have successfully developed a silver plastic chrysanthemum rubber tire. Chuck Yurkovich, senior vice president of Global R&D at Cooper Tire, said that even if only 10% to 15% of the original material is replaced with ginko, it is a huge success in reducing the demand for natural rubber.
The company's goal is to produce 100% tires using Acrylic rubber material without affecting its cost and performance.
Dandelion rubber is the closest material to the Hevea rubber and is expected to be a direct replacement. As early as 2007, Cooper and Bridgestone carried out tests on dandelion extracted rubber in Ohio, USA. Now, this special dandelion has been grown on a large scale in Europe and the United States. Wang Feng, Chairman of Shandong Linglong Tire Co., Ltd. pointed out that Linglong Tire has also established a research and development team for dandelion rubber, and it is expected that the developed dandelion rubber product can inherit 80% of the performance of natural rubber.

"Compared with the development of the first development of garcinia rubber and dandelion rubber in foreign countries, eucommia gum may be more suitable for China's national conditions. China has more than 95% of the world's Eucommia resources, and development of eucommia ulmoides has natural and monopolistic advantages, and is expected to crack China. Insufficient supply of natural rubber,†said Yuan Zhongxue, director of the National Rubber and Tyre Engineering Technology Research Center and chairman of the Soft Controls Co., Ltd., said that Gutta Percha is currently the only renewable special natural polymer new material in the world and is currently the only one in China. Natural gum with development potential alternative resources. The gutta percha is used in different ways in treads, sidewalls, triangle cores or belts, etc., which can significantly improve its performance and has a higher cost performance. At the same time, the new type of rubber from UCI has significantly extended the service life of existing tires and can reduce the amount of rubber consumed.
Synthetic rubber independent innovation progress
With the continuous improvement of environmental protection requirements in various countries, the current tire industry is developing in the direction of meridianization, flattening, and tubeless. This requires a large amount of synthetic rubber, environmentally friendly environmental protection products, and high-performance and functional synthetic rubber varieties. It has become the focus of R&D for rubber companies at home and abroad.
However, only a few enterprises in China have mastered the production technology of environmental protection products. Therefore, a considerable amount of synthetic rubber must be imported every year.
Professor Li Guixian of Lanzhou University of Technology believes that the transformation and upgrading of the synthetic rubber industry is imminent. He suggested integrating industry resources, making great efforts to do a good job of intellectual property protection, making great efforts to grasp independent innovation, and researching key technologies and products according to the needs of the market, and changing China’s key technologies and fields in the production of high-end products. status quo. Zhang Yiheng, a professor at Qingdao University of Science and Technology, pointed out that in the future development, the synthetic rubber industry should shoulder the historical responsibility of developing from a big synthetic rubber country to a strong synthetic rubber country, and leapfrog development in high-end technology, materials, equipment, etc., in high-end products. And made new breakthroughs in technology.
At present, many universities, research institutes and enterprises in China are carrying out extensive cooperation in production, teaching and research, and have made breakthroughs in the fields of high-end styrene-butadiene rubber, nitrile rubber, and butadiene rubber. “Soluble-polymerized styrene-butadiene rubber (SBR) is an essential material for the manufacture of green tires and has always depended on imports. The key technologies for the application of domestic SBR rubber in the manufacture of green tires have broken through foreign green technical barriers and significantly reduced raw material costs. A company can save hundreds of millions of yuan each year.†Ding Naixiu, a professor at Qingdao University of Science and Technology, said that the project solved the contradictory technical problems of rolling resistance, noise, and wet skid resistance at one stroke, allowing the traditional upgrade of rubber tires. It also enhances the international competitiveness of China's tire industry.
In addition, Qilu Petrochemical Rubber Factory, which has the largest synthetic rubber production capacity in the country, cooperated with Qingdao Science and Technology University and Beijing Chemical Industry Research Institute to conduct research on the development of a new molybdenum-based catalyst pilot process for the development of tread rubber industry, and a major breakthrough was achieved. Molybdenum-based high-vinyl butadiene rubber has laid a good foundation in the market.

Additives A variety of new products come out
In addition to natural rubber and synthetic rubber, tires are also heavily loaded with oils and fillers. It is understood that 67% of the world's carbon black is used as an active reinforcing agent in tire rubber, making the tire more resistant to abrasion, tearing, and more slippery. However, some nano-carbonate materials are used as inert fillers to improve the chemical resistance of tires, and some functions of reinforcing agents are also available after modification.
The recently listed Jinneng Technology Co., Ltd., the first raised investment projects include high-performance carbon black. "Using this high-performance carbon black to make tires can reduce pollutants by 20% to 30%, and it can increase the tire's rolling efficiency by 3% to 5%, which is not only more fuel-efficient, but also can extend tire life by about 10%." According to Gu Wenbin, Deputy General Manager of Energy Technology. At the same time, adding graphene to the tire rubber can also improve the wear resistance and grip of the tire. For this reason, Twinstar Group has set up a graphene tire center laboratory.
The world’s first intelligent production line for graphene conducting tires was put into operation at Qingdao Sen Unicorn Tire Co., Ltd. "Graphite conductive tires use graphene and colloidal composite modification preparation technology, its core function is to eliminate the need for additional vehicle equipment to derive static body." Lin Yulong, general manager of Sen Qilin tires, said that the company's production of graphene conductive Tires.

The thermal performance and mechanical strength have outstanding performance. Tensile strength, tear strength, rolling resistance and wet slippery properties are all improved by more than 50% compared with ordinary tires. It can reduce tire burst, improve vehicle driving safety and tire bearing capacity.
Carbon nanotubes are another hot topic in the industry. The material is a one-dimensional quantum material with a special structure, its electrical conductivity, thermal conductivity is usually up to 10,000 times that of copper, its tensile strength is 100 times that of steel, and its density is only 1/6 of that of steel. Wide range of cutting-edge materials.
At present, Shandong Fengyuan Tire Co., Ltd. has produced carbon nanotube tires that are recognized by the market. This type of tire has lower rolling resistance, higher wear resistance, lower carbon and energy saving than ordinary tires, and it can easily brake even on snowy roads in cold winters, and its service life is 30% higher than that of ordinary tires.
In addition, the international tire giant Goodyear Tire & Rubber Company announced that it will launch a new material tire in China. Its core raw material, silica, can be extracted from rice hulls. In the past two years, Goodyear has been researching and testing silica extracted from rice husk ash at Akron Innovation Technology Center. Silicon dioxide is used in tires compared to conventional tires that use carbon as a reinforcing agent.
The tire's rolling resistance can be reduced, which will help improve the vehicle's fuel efficiency. Coupled with the drainage of silica, it can effectively improve the wet grip performance of tires.
