The invention discloses a resistance-reducing and antifouling structure and a preparation method thereof, and relates to the technical field of resistance reduction and antifouling, each resistance-reducing and antifouling unit comprises a main rib structure, two secondary rib structures and two common rib structures, the two secondary rib structures are located on the two sides of the main rib structure respectively, and the two common rib structures are located on the outer sides of the primary rib structures respectively; the height of the main rib structure is greater than that of the secondary rib close to the main rib structure, the height of each secondary rib in the secondary rib structure is reduced from the direction close to the main rib to the direction far away from the main rib, and the height of the outermost secondary rib in the secondary rib structure is greater than that of the common rib; the main ribs of the anti-drag and anti-fouling units and the main ribs of the adjacent anti-drag and anti-fouling units in the longitudinal direction are located on the same straight line, and the anti-drag and anti-fouling units and the adjacent anti-drag and anti-fouling units in the transverse direction share one common rib. The surface of the anti-drag and anti-fouling structure has excellent anti-drag and anti-fouling effects, the situation that a traditional shark-imitating groove surface cannot give consideration to the anti-drag effect and the anti-fouling function is broken through, and anti-drag and anti-fouling integrated preparation is achieved.
本发明公开了一种减阻防污结构及其制备方法,涉及减阻防污技术领域,各减阻防污单元包括主肋结构、两个次肋结构和两个共用肋结构,两个次肋结构分别位于主肋结构的两侧,两个共用肋结构分别位于一次肋结构的外侧;主肋结构的高度大于靠近主肋结构的次肋的高度,次肋结构中各次肋的高度由靠近主肋向远离主肋的方向减小,次肋结构中最外侧的次肋的高度大于共用肋的高度;减阻防污单元的主肋与其在纵向上相邻的减阻防污单元的主肋位于同一直线,减阻防污单元与其在横向上相邻的减阻防污单元共用一个共用肋。本发明的减阻防污结构的表面具有优异的减阻防污效果,突破传统仿鲨鱼沟槽表面不能兼顾减阻效果和防污损功能,实现减阻防污一体化制备。
