China's tire related regulations and standards need to be in line with the tire label regulations and related new standards of some foreign countries, such as Europe, the United States, Japan and South Korea, which will be implemented one after another, putting forward higher requirements for tire wet grip, energy efficiency, wear, noise and service life. Industry experts recently unanimously suggested that, as a major tire exporter, China should timely integrate with the tire labeling regulations of the EU and other foreign countries, improve relevant regulations and standards, improve the formulation, process and equipment level of synthetic rubber raw materials, and keep up with the supporting needs of green tires

"the European Union is the second largest overseas export market of China's tires after the United States. To maintain this huge market share, manufacturers need to face the challenge. Modern tires require that the wet, rolling resistance, wear and other properties be improved without sacrificing other properties, so it is necessary to optimize the synthetic rubber process and speed up the production and processing technology research and development of high-performance synthetic rubber." Su Bo, director of the Information Office of the tire Research Institute of shuangqian group, said

he introduced that green tires have the advantages of good elasticity, low rolling resistance, low fuel consumption, low heat generation, wear resistance, puncture resistance, large bearing capacity and comfortable riding. At present, all countries are building relevant regulatory frameworks to promote the green development of tires. Among them, the tire labeling system aims to promote the low fuel consumption, low noise and high performance of tires to enhance the safety of highway transportation and improve economic and environmental efficiency. The EU tire labeling system and relevant mandatory standards, which will be implemented in november2012, are relatively strict and comprehensive tire labeling regulations, which put forward higher requirements for tire performance such as energy efficiency, slippery, noise and service life

lihuating, deputy chief engineer of Beijing rubber industry research and Design Institute, predicts that the global share of green tires will increase by more than 15% in the near future, driven by the new regulations. At the same time, it puts forward new requirements for the application of synthetic rubber and other related raw materials, including the development and change of various raw materials and matching technology, the change of production and processing technology, the use of new equipment, etc

"the rubber consumption of tires accounts for more than 60% of the total rubber output and is very environmentally friendly. The change of tire product structure also determines the variety change and technical development of tire rubber, including formula technology, process technology and new equipment technology. The key is to improve the quality and performance of products through the improvement of synthetic rubber performance, reduce production costs, improve work efficiency, achieve energy saving and consumption reduction of tires, and meet the requirements of environmental protection." Lihuating said

yangxiuxia, senior engineer of Sinopec economic and Technological Research Institute, also believes that the introduction and implementation of a series of regulations on tire safety, environmental protection and energy conservation represented by the EU tire labeling law, focusing on the implementation of key elements such as Juli personnel, enterprises, projects and parks, will rapidly increase the demand for high value-added rubber varieties such as SSBR (solution polymerized styrene butadiene rubber) and nd Br (neodymium based polybutadiene rubber). With the economic recovery, domestic synthetic rubber enterprises should speed up the construction of relevant product systems, strengthen cooperation with downstream tire enterprises, seize market opportunities, and jointly develop personalized products that meet the needs of high-performance tires

Su Bo believes that in order to adapt to the tire labeling system and relevant standards, China should speed up the improvement of SSBR processing and application technology and the development of new brands. "SSBR is used to manufacture the tread of green tires. It meets the requirements of automobiles for low rolling resistance, high wet skid resistance and wear resistance of tires. It can effectively reduce automobile fuel consumption. Accelerating the development of SSBR manufacturing and processing application technology is the core force to promote the industrialization of green tires in China." He said

in addition, nd BR and trans isoprene rubber are also current research and development hotspots. The rubber produced by neodymium polymer has strong wear resistance. When used to manufacture the tread and sidewall of green tires, it has high fatigue resistance, crack growth resistance and cutting ability. Combined with SSBR, it can ensure its high clutch and low rolling loss with the road surface, and reduce tire wear. Trans isoprene rubber can be blended and co crosslinked with natural rubber, styrene butadiene rubber, CIS butadiene rubber, CIS isoprene rubber, etc. the blended rubber has the characteristics of reduced rolling resistance and heat generation, improved wear resistance and fatigue resistance, which will make the tire more fuel-efficient, longer life and safer

compared with the introduction of tire labeling regulations and related standards abroad, the research and implementation of tire labeling regulations in China, including the promotion of labeling regulations, started late, resulting in the lack of necessary response measures for the introduction of mandatory EU regulations by some domestic synthetic rubber and tire enterprises. In this regard, Su Bo suggested that China should speed up the pace, strive to integrate with the international energy efficiency labeling system as soon as possible, and further improve the technical level of the synthetic rubber and tire industry

"The formulation of energy efficiency standards is the basis for carrying out the labeling system for energy-saving products. China should speed up the revision and formulation of energy efficiency standards for tire products. First, we should strengthen the publicity of energy efficiency standards and tire labeling system, so that enterprises pay attention to the production of energy-saving tire products, so that consumers can understand and understand energy-saving products. Second, we should collect information on relevant laws and regulations of technologically advanced countries, and understand their implementation objectives, technical requirements, testing methods and recognition Certification methods, time nodes and other key contents, so that the technical improvement and promotion work can be implemented synchronously with the laws and regulations. " Su Bo said, "we should learn from the successful international experience and further study the feasibility and methods of implementing the tire labeling system in China, so as to promote the development of domestic high-performance energy-saving supporting raw material products with full orders. We should increase investment in research and development, including training talents, introducing technology and allocating resources, so as to make the technical level of raw materials and tires meet or exceed the regulatory requirements in the shortest possible time."

at present, there are no relevant tire standards, regulations and mandatory standards in China. According to lihuating, at present, the formulation of relevant standards for domestic green tire products has been started. The tire rolling resistance limit standard has been determined and will soon become a mandatory standard. At the same time, it also points out the direction for the follow-up of synthetic rubber
