Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0025] figure 1 It is a schematic diagram which shows the basic structure of the water-skiing surface structure in this embodiment, (a) is a cross-sectional view, (b) is a top view. figure 2 It is a cross-sectional view of a hard bump showing an enlarged basic structure of the water-skiing surface structure in this embodiment.

[0026] Such as figure 1 As shown, the glass substrate (substrate) 20 of the water slide glass 10 has a plate shape and can transmit visible light. The water slide glass 10 is provided with a water slide layer 30 on at least one surface of the glass substrate (substrate) 20. Moreover, this water ski layer 30 is composed of a hydrophobic layer 31, a hard layer 40, and a buffer layer 33.

[0027] The hard layer 40 is an assembly of hard protrusions 41. The top ends of these hard protrusions 41 are convex and the shape is roughly conical. They are e...

Abstract

The invention is aimed to provide a water slipping surface structure having high durability particularly against the wiping action by a wiping member such as a wiper in a water slipping glass keeping water slipping effect over a long time. In the surface structure of the water slipping glass 10 in which the water slipping property of droplets dropped on a glass substrate 20 is improved, a water slipping layer 30 provided with a hard layer 40 which consists essentially of a high hard material having a higher hardness than that of the glass substrate 20 and in which the projecting and recessed shapes are continuously formed, and a water repellent layer 31 filled in the recessed part of the hard layer 40 and comprising a water repellent material having >=90[deg.] contact angle with the dropped droplets is formed on the surface of the glass substrate 20.

Description

Technical field [0001] The present invention relates to a water-skiing surface capable of maintaining the water-skiing effect for a long time, and more particularly to a water-skiing surface structure having high durability for the wiping action performed by wiping components such as wipers. Background technique [0002] In order to prevent the deterioration of the visual field, people have taken some measures to make the surface of the window glass of the car hydrophobic, and try to improve its water slidability, that is, the performance of moving the water droplets attached to it by its own weight. As a means for improving the water slidability, a method of coating a glass surface with a fluororesin has conventionally been used. Through such a fluororesin coating method, the hydrophobicity of the glass surface is improved, and water droplets, oil droplets and dirt are not easily attached. [0003] However, the adhesion between the fluororesin and the glass is not good, and the ...
