Summary, etc. <p>In order to improve the chemical resistance of epoxy resin and its toughness and corrosion resistance, in this paper, silicone modified epoxy resin was prepared with epoxy resin and two kinds of silicones, Dow Corning DC–3074 and Chenguang Z–1, as raw materials and dibutyltin dilaurate (DBTDL) as catalyst. The structure of the modified epoxy resin was characterized by Fourier transform infrared (FTIR) spectrometer and its performance was tested. The results showed that the epoxy resin modified by DC–3074 had better salt spray resistance compared with the Z–1. Therefore, the DC–3074 was selected as the epoxy resin E–51 modifier. The silicone modified resin was further synthesized with E–51 as the matrix resin, 12.5% DC–3074 silicone as the modifier, and 0.5% DBTDL as the catalyst. The obtained cured coatings showed good performance with the following results: product fineness of 20–25 μm, solid content of more than 95%, surface drying time of 25 min, smooth appearance, hardness of 2 H, adhesion level of 0, and salt spray resistance time of 432 h. The prepared modified epoxy resin coating has good salt spray resistance and good application prospect.</p>
