摘　　要：选用自行设计合成的梯形聚甲基倍半硅氧烷Ⅰ和梯形聚苯基倍半硅氧烷Ⅱ为基料,添加适量的钛白粉、滑石粉等填料和适当溶剂,研制出了耐高温抗粘涂料。该涂料能经受550℃的高温;蒸馏水、正庚烷、0#柴油、甲苯在钢片涂层上的接触角分别为110.5°、29.6°、35.6°、38.2°;在盐水、酸性和碱性溶液中浸泡7天后,钢片涂层不起泡,具有很好的耐盐水和耐酸碱性能。A high-temperature resistant coating was synthesized with ladderlike polymethylsilsesquioxane I and ladderlike polyphenylsilsesquioxane Ⅱ as basic material, and titanium dioxide, talc and proper solvent as additives. It can resist high temperature of 550℃. Thecontact angle of distilled water, heptane, 0# diesel oil, toluene on steel coatings is 110.5 ℃ , 29.6℃, 35.6 ℃ and 38.2 ℃. After dipping in the brine, acid and alkaline solution for 7days, the steel sheet coating has no bubble, which shows thecoatings posed excellent thermal stability, salt-water and acid-alkari resistance.
