The invention discloses an anti-drag coating as well as a preparation method and application thereof. The anti-drag coating comprises the following components: epoxy resin, a fluorosilicone modifier, a modified silicon dioxide filler, an amine curing agent, a plasticizer, a solvent and a defoaming agent, wherein the fluorosilicone modifier is prepared by firstly reacting hexafluoropropylene oxide dimer with methanol and then reacting with N-[3-(trimethoxysilyl) propyl] ethylenediamine; the modified silicon dioxide filler is obtained by modifying nano silicon dioxide powder and a fluorosilicone modifier according to the weight ratio of 1: (0.02-0.2), and the drag reduction coating can fully infiltrate the surface of a ship matrix and is cured to form a drag reduction layer with the super-hydrophobic characteristic, the excellent mechanical property and the self-repairing capacity; in addition, the drag reduction layer adopts a specific groove structure, so that the drag reduction rate of the drag reduction layer can be increased to 57.4% or above.

    本发明公开了一种减阻涂料及其制作方法和应用,该减阻涂料的组分包括环氧树脂、氟硅改性剂、改性二氧化硅填料、胺类固化剂、增塑剂、溶剂和消泡剂;其中,氟硅改性剂由六氟环氧丙烷二聚体先与甲醇反应再与N‑[3‑(三甲氧基硅基)丙基]乙二胺反应制得;改性二氧化硅填料由纳米二氧化硅粉体与氟硅改性剂按照重量比1:(0.02~0.2)改性得到,该减阻涂料能够充分浸润船舶基体表面,固化形成了具备超疏水特性、优异力学性能以及自修复能力的减阻层;并且,减阻层采用特定沟槽结构,能够使得减阻层的减阻率提升至57.4%以上。
