Abstract: The methyl silicone resin sealant with good performance is synthesized by copolymerization and condensation of tetraethoxysilane (TEOS),methyl trimethoxysilane (MTMS),dimethyl dimethoxy silane,silicone resin and glacial acetic acid.The influences of the molar ratios among raw materials in the reaction system on the performance of sealant are investigated.The hardness and corrosion resistance of sealant film coated on the nickel-plated plate are analyzed and studied.Fourier transform infrared spectrometer,EIS and scanning electron microscopy are used to characterize the morphology and microstructure of resin film.Results show that the hardness of the sealant film formed on nickel-plated plate can reach 5 H and the immersion test in salt solution can reach 96 h when the molar ratio of TEOS to MTMS is 1∶0.65,the mass content of silicone resin in the reaction system is 3%,the mass content of dimethyl dimethoxy silane is 5% and pH of reaction system is 4.5.
