Title:
WATER-REPELLENT BASE MATERIAL AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2017/110200
Kind Code:
A1
Abstract:
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.
