The hottest new material, green tires, makes cars

New materials green tires make cars more fuel-efficient

recently, at the third China rubber materials development forum held by the rubber materials special committee of China Rubber Industry Association, Wang Fengju, Secretary General of the rubber materials special committee of China Rubber Association, said that according to the regulations on the management of fuel consumption identification of light vehicles issued by the Ministry of industry and information technology, from January 1, 2010, most passenger cars and light commercial vehicles must be marked with the actual fuel consumption when they are sold. At that time, the fuel economy requirements of automobile manufacturers for only one yellow abetting tire after power on will be greatly improved. The development of green tires is the general trend, and downstream tire enterprises must actively prepare for the application of new materials to develop green tires

vehicles equipped with green tires can achieve the goal of substantial emission reduction and reduce fuel consumption without changing the body. Generally, green tires can reduce rolling resistance by about 26% and save fuel by 3%-8%. At the same time, the performance indicators of tires, such as wear resistance, low noise, dry and wet road grip, are maintained at a relatively ideal level. According to Michelin company statistics, if the rolling resistance of tires is reduced by 20%, each vehicle can save 23 liters of fuel per year. While solution polymerized styrene butadiene rubber, rare earth butadiene rubber, high vinyl butadiene rubber, etc. meet the requirements of high-speed, energy-saving, safe and environmental protection of high-performance tires (2) adopt the requirements of wheel amplitude load sensor, Green production means that "the environmental conditions (including platform environment) around the tested product created by the experimental equipment should meet the requirements of environmental conditions and tolerance specified in the product experimental specifications "Tires are indispensable new rubber materials.

Wang Fengju said that SSBR has high anti-skid performance and does not increase rolling resistance. At present, China has the conditions to supply SSBR. For example, the products produced by the 100thousand ton/year SSBR plant of Sinopec Gaoqiao Company have been recognized by the market, and the 100thousand ton/year SSBR plant of PetroChina Dushan subsidiary will be put into operation in 2010.

China Petroleum Technology Wangguilun, senior director of the division, also introduced that rare earth butadiene rubber is superior to nickel butadiene rubber currently used in terms of wear, heat generation, fatigue, aging and rolling resistance, and should be gradually replaced. At present, the 15000 ton/year rare earth butadiene rubber plant of Dushan subsidiary has successfully realized pilot production, and will eventually form a complete set of process technology with independent intellectual property rights. In addition, environmentally friendly rubber filling oil and high vinyl butadiene rubber series that meet the requirements of EU REACH regulations are being actively developed

it is understood that the EU stipulates that all new cars must be equipped with green tires with low rolling resistance from 2012. The new energy policy formulated by the Obama administration also requires that the average mileage of cars per gallon of gasoline must reach 351 by 2016. First, check the displacement sensor Five miles. These Regulations of European and American countries put forward higher requirements for China's exported tires. Domestic tire enterprises must speed up production transformation and expand the application of new materials in order to meet the environmental protection and energy conservation requirements of modern society
