Nano tire fuel-saving 5% will be listed on the market

A national 863 project undertaken by Beijing University of Chemical Technology and other units was approved recently. The name of this topic is: The scaled preparation technology of nano-elastomer composite materials for high-performance tires.

At present, new fuel-saving and safety tires developed using this technology have entered the mass production phase and will soon be on the market. According to reports, after assembling this new type of nano-tire, the fuel consumption of the sedan can be reduced by about 5% compared with the existing ordinary radial tire.

In addition to the shape of the car, vehicle weight and engine efficiency, the tire is also one of the key links in fuel economy. When the vehicle is running, the soft rubber tire is crushed and deformed by the road surface, and a large number of sliding frictions are formed inside, and the resistance increases to consume more fuel.

The tires developed by Beijing University of Chemical Technology are "smart". “We changed the internal structure of the tire tread rubber material. The intermolecular sliding force can be large when braking, and it is small when driving, which has achieved the purpose of fuel saving.” said Wang Yiqing, associate researcher of the State Key Laboratory of Organic Inorganic Composite Materials of Beibei Chemical Industry. .

According to reports, the fuel-saving mystery of the new tires lies in the use of solution-polymerized styrene-butadiene rubber. The overall performance of this material is superior to other traditional tire raw materials. In addition, fuel-saving tires also have a secret weapon - white carbon black.

Wang Yiqing said that in the past, the manufacture of tires required the addition of carbon black to the raw materials, which could help the rubber to resist ultraviolet rays and prevent the rubber from “aging” too quickly. However, there is a layer of scales on the surface of the carbon black, and the rubber is adsorbed on the scales. When the tire rolls, there is a slip between them and the frictional resistance increases. The structure of white carbon black and carbon black is different, the surface is smooth, and the rubber is chemically bonded. When the tire rolls, the frictional resistance can be minimized.

After actual calculation in the sports field, the new type of tires can save 5% of the radial tires currently used in large quantities, and the tires have now entered the factory production stage, and it is planned to form a capacity of one million sets per year.

It is reported that new tires will be mass-produced by domestic tire companies such as Linglong. A scientific and technological innovation result, which has just passed acceptance, can be transformed into productivity. Behind the “quick speed”, the shadow of the property rights alliance between research institutions and production companies is flashing.

According to the analysis, the tire company has a large scale of production. When the factory tests new technologies, it needs to suspend some of the production processes, which will cause production confusion; and the school provides test funding, but not enough to make up for the loss of the tire factory. If the scientific research department and the enterprise share scientific research results, the tire company can give priority to the use of the results, schools and research companies form a de facto alliance of property rights, and increase the enthusiasm of business participation. In addition, the company provides market information at the same time and finds the direction for scientific research.
