Rubber nanocomposile cross-scale design contributes to the successful development of AA1 products.

With the depletion of petroleum resources and the increasing greenhouse effect, energy conservation, emission reduction and environmental protection have attracted more and more attention from all over the world. Countries such as the European Union and Japan rose to the regulatory level in 2010 on tire rolling resistance and slippery, noise requirements. In order to meet the highest requirements of the EU labeling law, Shandong Lingling Tire Co., Ltd. Research Institute and Beijing University of Chemical Engineering Advanced Elastomer Materials Research Center set up a special research group to deal with the EU label law the highest level of "AA1" level tires, the development of a new high-level high-grade tire products
New products, with the help of Lingling Tire Research Institute and Beijing Chemical University's National Key Laboratory Research Platform for Organic Inorganic Composites, combine basic research such as cross-scale simulation calculation, nano-enhanced rubber permeable-stick mechanism with the development of high-performance tread gel nanocomposite formulations, scientifically apply special new materials, develop advanced continuous method mixing technology, realize the network structure regulation and functional coupling of multi-component multi-scale materials, and scientifically design tire structure and pattern arrangement. The new product can effectively reduce the sliding distance between the tire and the ground when braking, greatly improve the safety performance of the tire on wet road surface, and also significantly reduce the energy loss of the tire in the process of use, saving the vehicle fuel consumption.
completed the development of 2 specifications by July 2019, all reaching the AA1 level. 205/55R16, 235/55R19 specifications of the rolling resistance of products below 6.0, wet slip index of more than 1.60, through noise 68dB, the indicator reached the EU label law AA1 level, in the wet slip and roll resistance parameters performance is better than the EU label regulatory requirements. At present, the product has been in Lingling tires at home and abroad vehicle supporting projects on the successful application.
current maximum rating of the EU labeling method is AA1, i.e. wet slip index A, rolling resistance A, noise level 1. The successful research and development of Lingling Tire AA1 project fully reflects the company's research and development level, reflects the strength of cooperation between industry, science and research, and provides a solid technical guarantee for the company to continue to explore the European market and enhance brand value.
's leading research and development strength is lingling tires for many years such as day-to-day research and development investment and innovation. It is understood that Lingling tires in Tsingyuan, Yantai, Beijing, Shanghai, Germany, the United States set up research and development institutions, with a national industrial design center, the national identification of enterprise technology center, national accredited laboratory, to build a global coverage of integrated research and development pattern. Up to now, Lingling Tire has participated in the formulation and revision of 91 national and industry standards, undertaken 11 national innovation projects, granted more than 700 patents, patents in the forefront of China's tire enterprises. Successfully developed graphene to strengthen tread tires, 3D printing ultra-low heat and high-cut polyurethane tires, racing tires, air-deficase tires, low-odor tires, dandelion rubber tires, etc., to participate in the national large aircraft meridian tire advanced composite materials and structure design and manufacturing basic research, and independent research and development of urban rail transit products. Won the second prize of national technology invention, the second prize of national scientific and technological progress two national science and technology awards.
