Publication number: 20240327285Abstract: The present disclosure discloses an organic silicon nano-precursor medium transmission inhibitor and its preparation method and use. The organic silicon nano-precursor medium transmission inhibitor is composed of an organic silicon and its derivatives, a catalyst, a dispersant, a stabilizer, a surfactant, and water. The organic silicon nano-precursor medium transmission inhibitor in-situ generates nanoparticles during a hydration process. The nanoparticles not only have a hydrophobic function, but also can effectively fill the pores of the concrete, which effectively solves a problem in which a hydrophobic material in a state of full water cannot reduce the diffusion of an erosive medium. The problems such as uneven dispersion and poor stability of nanoparticles added can be effectively solved by in-situ generating the nanoparticles, thereby effectively improving the ion corrosion resistance performance of the concrete.Type: ApplicationFiled: June 30, 2020Publication date: October 3, 2024Inventors: Jiaping LIU, Jingshun CAI, Song MU, Jianzhong LIU, Xiaocheng ZHOU, Qi MA, Pengcheng WU, Jinxiang HONG
