The domestic organic silicon materials laboratory recently announced the completion of the technological breakthrough for a new generation of highly regular ethyl silicone oil. Through continuous anionic ring opening polymerization process, the spatial arrangement error of the ethyl side chain has been controlled within 2% for the first time, completely solving the industry problems of low-temperature viscosity drift and high-temperature oxidation of traditional ethyl silicone oil.
The core performance of this cutting-edge modified ethyl silicone oil has achieved a leapfrog improvement: it remains in a fluid state even in ultra-low temperature environments of -85 ℃, there is no significant volatilization loss under continuous working conditions at 180 ℃, and the total residual amount of metal ions is less than 0.3ppm, fully meeting the special lubrication needs of cutting-edge equipment such as deep space exploration and deep-sea submersibles. Unlike the hybrid ethyl silicone oil produced by traditional processes, the new material improves its continuous service life in extreme environments from 2000 hours to over 12000 hours through precise sealing design of molecular chain end groups. At present, the technology has completed pilot testing and the first round of adaptation testing by downstream aerospace institutes shows that as a space attitude control shock absorber fluid, its performance indicators comprehensively surpass those of similar imported products, marking China's official breakthrough of overseas technology monopoly in the field of special low-temperature silicone oil.
