                      摘要：以环氧 E-12 为基体树脂，改性酚类为固化剂，K-7318 为固化促进剂，可有效降低固化温度；以
                  SA-186 为粗糙剂，加入经 1H,1H,2H,2H-全氟辛基三乙氧基硅烷修饰的纳米 SiO 2 和氟蜡，可有效提高疏水
                  性；加入适量石墨烯，可有效提高防腐性能。 通过熔融挤出、磨粉，成功制备了低温固化超疏水防腐粉末涂
                  料。 通过 SEM、TEM、中性盐雾、耐冲击、接触角测试等方法对低温固化超疏水防腐涂层性能进行了表征和
                  测试，考察了固化剂及固化促进剂对固化温度的影响；考察了改性纳米 SiO 2 、氟蜡和石墨烯用量对涂层疏
                  水性和防腐性的影响。 结果表明，经优化后的涂层具有优异的疏水性、防腐性能和机械性能。

                     Abstract:; Low temperature curing hydrophobic anticorrosive powder coatings were successfully
                  fabricated via melt extrusion and grinding methods using epoxy resin E -12 as binder; modified
                  phenolic as curing agent; K-7318 as curing accelerator and SA-186 as coarse agent. It is revealed
                  that curing temperature can be effectively reduced. Meanwhile, the hydrophobic property and
                  anticorrosion can be improved using 1H,1H,2H,2H - Tridecafluoro -n -octyltriethoxysilane
                  functionalized nano -SiO2 particle, fluorine wax and graphene. The coating properties were
                  characterized by SEM, TEM, neutral salt spray, impact resistance and contact angle tester, etc. The
                  effects of the curing agent dosage and curing accelerator dosage on the curing temperature were
                  examined. In addtion, the effects of the curing accelerator, fluorine wax, functionalized nano-SiO2
                  particle and graphene dosage on the hydrophobic property and anticorrosion of the coating were
                  investigated. The results showed that the optimized coating had excellent hydrophobic, anticorrosion
                  and mechanical properties.
