摘要：
With phenyltriethoxysilane (PTES) and β-3, 4-cyclohexyl epoxy silane preparation oxygen radicals (A186) as raw material, mixing methanol and ethanol as solvents, the reaction is carried out under acidic conditions to prepare compounds with Si-H bonds called epoxy oligosilsesquioxane(EP-POSS). The structures of the compounds were characterized by Fourier transform infrared (FT-IR), nuclear magnetic resonance (1H NMR), and nuclear magnetic resonance (29Si NMR). The epoxy resin was modified with the prepared EP-POSS, and the influence of the amount of EP-POSS on the adhesion, impact resistance, hydrophobicity and heat resistance of the resin coating was analyzed. The results showed that when the amount of EP-POSS is 5%, the adhesion of the epoxy resin coating reached grade 1, the impact resistance reached 50 cm, the contact angle to water is 90°, and the thermal stability is greatly improved. © All Right Reserved.
