water-repellent structure of the inclined structure surface, and water-repellent molded article with its water-repellent structure

摘要

The present invention weatherability by implementing water repellency by a groove or projection provided at larger intervals than the particle size of the water spray particles, to improve the durability such as abrasion resistance, without repair or refurbishment, etc. water-repellent structure of the inclined structural surface to be able to sustain the water-repellent effect, and, and there is provided a water repellent shaped article having the water-repellent structure. SOLUTION: In the water-repellent structure of the inclined structure surface to be inclined at a predetermined angle or more, so as to form a cusp-shaped projection 2 consisting of shape that the tip was pointed at predetermined intervals, in the apex-shaped protrusion 2, valley from the top Toward a plurality of grooves 5 and 6 gradually becomes shallower, so as to form a larger interval than the particle size of the water spray particles is continuous valley 3 between cusp-shaped projection 2 is bent in a zigzag line symmetry, this valley 3 It wants to form another valley 4 that intersect at right and left like an angle to the bent portion.BACKGROUND 1
