WATER-REPELLENT SURFACE MATERIAL
PROBLEM TO BE SOLVED: To provide a water-repellent surface material excellent in drainage performance and an antifouling property.SOLUTION: A water-repellent surface material 1 comprises a drainage structure part 10 being 90 degrees or more in a water contat angle of a surface, and the drainage structure part 10 comprises a plurality of projection parts 11 and a plurality of recessed parts 12 juxtaposed alternately, and respective ones of the plurality of projection parts 11 and the plurality of recessed parts 12 extend in a line shape along the drainage direction, and are inclined along the drainage direction, and in a cross section orthogonal to the drainage direction, (a) an angle θ formed by two virtual straight lines L1 and L2 of connecting the apex P of the projection parts 11 and the respective lowest points Q1 and Q2 of the two recessed parts 12 adjacent to the projection parts 11 is 160 degrees or less, and (b) a height (h) from the lowest point Q of the apex P is 5 mm or less, and (c) a distance (d) between the adjacent apexes P is 8 mm-20 mm.SELECTED DRAWING: Figure 4
【課題】排水性及び防汚性に優れた撥水性表面材を提供する。【解決手段】撥水性表面材１は、表面の水接触角が９０度以上である排水構造部１０を備え、排水構造部１０は、交互に並んだ複数の凸部１１及び複数の凹部１２を有し、複数の凸部１１及び複数の凹部１２の各々は、排水方向に沿ってライン状に延び、かつ、排水方向に沿って傾斜しており、排水方向に直交する断面において、（ａ）凸部１１の頂点Ｐと凸部１１に隣接する２つの凹部１２の各々の最下点Ｑ１及びＱ２とを結んだ２つの仮想直線Ｌ１及びＬ２がなす角度θは、１６０度以下であり、（ｂ）頂点Ｐの最下点Ｑからの高さｈは、５ｍｍ以下であり、（ｃ）隣り合う頂点Ｐ間の距離ｄは、８ｍｍ以上２０ｍｍ以下である。【選択図】図４
