Anti-icing wing leading edge

一种防冰机翼前缘

Abstract

一种防冰机翼前缘,包括机翼前缘壳体和位于壳体外部的防冰涂层,该防冰涂层包括底漆和面漆,所述底漆为环氧富锌底漆、面漆为有机硅改性丙烯酸酯涂料;底漆和面漆的干膜厚度分别为14微米和32微米;所述有机硅改性丙烯酸酯涂料包括:按重量计,有机硅改性丙烯酸树脂55-65%,颜色填料20-25%,纳米二氧化硅3%,纳米氧化锌3%,流平剂1%,消泡剂0.8%,分散剂1.2%,催化剂0.5%,溶剂3-5%。根据本发明的机翼前缘能够有效减少冰层在机翼前缘上的形成,且有利于已经形成的冰层的脱落。
An anti-icing wing leading edge comprises a wing leading edge shell and an anti-icing coat positioned outside the shell, the anti-icing coat comprises a primer and a finish, the primer is an epoxy zinc-rich primer, and the finish is an organosilicon modified acrylate coating; the thicknesses of the dry films of the primer and the finish are 14mum and 32mum respectively; and the organosilicon modified acrylate coating comprises 55-65wt% of an organosilicon modified acrylic resin, 20-25wt% of a color filler, 3wt% of nano-silica, 3wt% of nano-ZnO, 1wt% of a leveling agent, 0.8wt% of an antifoaming agent, 1.2wt% of a dispersant, 0.5wt% of a catalyst and 3-5wt% of a solvent. The wing leading edge made in the invention can effectively reduce the formation of ice layers on the leading edge of a wing, and is in favor of the shedding of formed ice layers.
