Recently, the world's longest-lasting automobile shock absorber oil seal was born in Anhui Province. Anhui Zhongding Seals Co., Ltd. and Anhui University have overcome the "bottleneck" of rubber-based ceramic nano-powder dispersion technology and developed rubber ceramic nanocomposites with excellent performance.
The most difficult thing about nanotechnology is not the preparation of nano-powders, but the application of nano-materials, and the most important technology to solve the agglomeration of nano-powders and achieve dispersion. In 2005, Zhongding Co., Ltd. and Anhui University jointly implemented the national science and technology research topic - rubber nanocomposites and automotive rubber parts products research and development. After one and a half years, the research team prepared rubber ceramic nanocomposites with excellent performance, and developed the automotive rubber for the automobile shock absorber oil seal, the EPDM rubber wear-resistant rubber hose and the shock absorber rubber for the automobile. Main parts and components. Tested by the testing center of the Shanghai Rubber Products Research Institute, the national statutory testing institution, the life of the oil shock absorber of the automobile shock absorber has reached more than 15 million times, which is 3 to 5 times higher than that of the domestic similar products, and is obviously superior to similar foreign products. The life span of EPDM rubber wear hose has reached more than 1 million times, ranking the international advanced level. The dynamic durability of the stopper rubber for automobile shock absorbers has been greatly improved, reaching the domestic advanced level. At present, all three products have been trial-produced in small batches.
