Title (EN) WATER-REPELLENT BASE MATERIAL AND METHOD FOR MANUFACTURING SAME
(FR) MATÉRIAU DE BASE HYDROFUGE ET SON PROCÉDÉ DE FABRICATION
(JA) 撥水性基材とその製造方法
Abstract:
(EN) This water-repellent base material (1) includes an aluminum base material (2), an alumite layer (3) provided on a surface of the aluminum base material, and a water-repellent coating (4) provided on a surface of the alumite layer. The alumite layer has a base layer (31) integrated with the aluminum base material, and a surface relief structure (33) formed from a plurality of pin-like protrusions (32) provided side-by-side on a surface of the base layer. With respect to the ten-point average roughness Rzjis of the surface relief structure, the contact surface area ratio of the pin-like protrusions is 0.01 or less in a virtual cross section (A) at a height at which the Rzjis cut ratio is 20% from the position of the maximum height of the surface relief structure, and the water-repellent coating is formed from a hydrocarbon-based water-repellent material.
(FR) Cette invention concerne un matériau de base hydrofuge (1), comprenant un matériau de base en aluminium (2), une couche d'alumite (3) disposée sur une surface du matériau de base en aluminium, et un revêtement hydrofuge (4) disposé sur une surface de la couche d'alumite. La couche d'alumite possède une couche de base (31) intégrée au matériau de base en aluminium, et une structure de surface en relief (33) formée d'une pluralité de protubérances en forme de broches (32) disposées côte à côte sur une surface de la couche de base. En ce qui concerne la rugosité moyenne d'après dix points Rzjis de la structure de surface en relief, le rapport de surface de contact des protubérances en forme de broches est inférieur ou égal à 0,01 dans une section transversale virtuelle (A) à une hauteur à laquelle le rapport de découpe Rzjis est de 20 % par rapport à la position de la hauteur maximale de la structure de surface en relief, et le revêtement hydrophobe est formé à partir d'un matériau hydrophobe à base d'hydrocarbures.
(JA) 撥水性基材(1)は、アルミニウム基材(2)と、該アルミニウム基材の表面に設けられたアルマイト層(3)と、該アルマイト層の表面に設けられた撥水皮膜(4)とを備える。上記アルマイト層は、上記アルミニウム基材と一体の基層(31)と、該基層の表面に並立する多数のピン状突起(32)とからなる凹凸構造(33)を有し、該凹凸構造の十点平均粗さRzjisに対し、上記凹凸構造の最大高さ位置からRzjisカット率20%となる高さの仮想切断面(A)において、上記ピン状突起の接触面積率が0.01以下であり、上記撥水皮膜は、炭化水素系撥水材料からなる皮膜である。
