The tire labeling regulations and related new standards in Europe, the United States, Japan, and South Korea will soon be implemented in succession, placing higher requirements on tire wet grip, energy efficiency, wear, noise, and service life. Industry experts recently agreed with an interview: As a big tire exporter, China should promptly integrate tire label regulations and regulations in the EU and other countries, improve relevant regulations and standards, improve the level of synthetic rubber raw materials, processes and equipment, and keep up with the demand for green tires.
“The EU is the second largest overseas export market for tires in China, second only to the United States. Maintaining this huge market share requires manufacturers to face challenges. Modern tires require improved performance in terms of wet skid, rolling resistance and wear, without sacrificing performance. For other properties, it is necessary to optimize the synthetic rubber process and accelerate the research and development of high-performance synthetic rubber production and processing technologies, said Su Bo, head of intelligence research at the Double Money Group Tire Research Institute.
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 carrying capacity, and comfortable ride. 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 tires with low fuel consumption, low noise, and high performance to enhance the safety of road transport and improve economic and environmental efficiency. The European Union's tire labeling system and related mandatory standards, which will be implemented in November 2012, are stricter and comprehensive tire labeling regulations, and impose higher requirements on the tire's energy efficiency, wet skid, noise, and service life.
Li Huating, deputy chief engineer of the Beijing Rubber Industry Research and Design Institute, predicts that under the impetus of the new regulations, the global share of green tires will increase by more than 15%. At the same time, new requirements for the application of raw materials such as synthetic rubber will be put forward, including the development and changes of various raw materials. With the changes in technology, production and processing technology changes, the use of new types of equipment.
“The consumption of tire rubber accounts for more than 60% of the total rubber production. The change in tire product structure also determines the variety and technology development of rubber used in tires, including formulation technology, process technology and new equipment technologies. The key is to improve the performance of synthetic rubber. Improve product quality and performance, reduce production costs, improve work efficiency, achieve energy saving and consumption reduction of tires, and meet environmental protection requirements, said Li Hua Ting.
Yang Xiuxia, a senior engineer of the Institute of Economics and Technology of SINOPEC, also believes that the introduction and implementation of the series of tire safety, environmental protection, and energy saving standards represented by the European Union's tire labeling method will make SSBR (Soluble Polymerized Styrene Butadiene Rubber) and Nd-BR The demand for high value-added rubber products such as polybutadiene rubber has rapidly increased. Domestic synthetic rubber enterprises should speed up the construction of related product systems, strengthen cooperation with downstream tire companies, 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 related standards, China must accelerate the improvement of SSBR processing application technology and the development of new brands. “SSBR is used to make green tire treads to meet the requirements of low tire roll resistance, high wet skid resistance and abrasion resistance of automobiles. It can effectively reduce vehicle fuel consumption and accelerate the development of SSBR manufacturing and processing application technology is to promote domestic The core force of green tire industrialization," he said.
In addition, Nd-BR and trans-isoprene rubber are also current research hotspots. The rubber produced from lanthanide polymers has high abrasion resistance. When used to make treads and sidewalls of green tires, it has high fatigue resistance and resistance to crack growth and cutting. Combined with SSBR, it can ensure high surface resistance. Coupling and low roll loss while reducing 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 resulting blended compound has rolling resistance and heat reduction, abrasion resistance and resistance. Features such as increased fatigue, make the tire more fuel-efficient, longer life, and more secure.
Compared with the introduction of tire label regulations and related standards in foreign countries, China’s research and implementation of tire labeling regulations, including the promotion of labeling regulations, started relatively late, resulting in the lack of the introduction of EU mandatory regulations for some domestic synthetic rubber and tire companies. Necessary countermeasures. In this regard, Su Bo suggested that China should speed up the pace for the early integration with the international energy efficiency labeling system and further improve the technical level of the synthetic rubber and tire industry.
“Establishment of energy efficiency standards is the basis for launching energy-saving product labeling systems. China should pay close attention to the revision and formulation of energy efficiency standards for tire products. First, it must strengthen the promotion of energy efficiency standards and tire labeling systems so that enterprises can focus on the production of energy-saving tire products. , to enable consumers to understand and recognize energy-saving products; Second, to collect information on relevant laws and regulations in advanced technology countries, and to understand key objectives such as its implementation objectives, technical requirements, testing methods, certification methods, and time nodes, so that technical improvements can be synchronized with laws and regulations. Implementing,†said Su Bo, “we should learn from international successful experience to further study the feasibility and methods of implementing the tire labeling system in China in order to promote the market development of high-performance energy-saving auxiliary raw material products in China. We should increase investment in R&D, including the training of talents. , the introduction of technology, and the allocation of resources to bring the raw material and tire technology levels to meet or exceed regulatory requirements in the shortest possible time."
At present, China has no relevant tire standards and mandatory standards. According to Li Huating, at present, the formulation of relevant standards for domestic green tire products has been initiated, and the tire rolling resistance limit standard has been determined and will soon become a mandatory standard. At the same time, it also indicates the direction of follow-up for synthetic rubber.
