Problems solved by technology

[0005] However, in the structure described in Patent Document 1, the entire microporous layer contains a fluororesin, the affinity between the microporous layer and the waterproof material is high, and a large amount of waterproof material can be retained, but the waterproof material inside the microporous layer It is difficult to supply to the surface of the fine porous layer, and there is a possibility that the waterproof material cannot be fully utilized, and the waterproofness may decrease
[0006] In addition, if the affinity between the fine porous layer and the waterproof material is low, a sufficient amount of the waterproof material cannot be retained.

Embodiment 1

[0098] (Preparation of coating liquid)

[0099] 50 mmol of water, 11 mmol of triethylene glycol, and 13 mmol of isopropanol were uniformly mixed, and 0.2 g of 32N sulfuric acid was added to prepare a solution A.

[0100] Next, solution B was prepared by mixing 54 mmol of tetraethoxysilane and 13 mmol of isopropanol.

[0101] The above-mentioned solution A and the above-mentioned solution B were mixed, stirred by a stirrer for 15 minutes, and a sol was prepared. This sol solution was diluted 5 times with ethanol to prepare a coating solution.

[0102] (coating)

[0103] The above coating solution was applied on soda lime glass by the spin coating method (rotation speed: 2000 rpm, rotation time: 20 seconds, humidity 60%).

[0104] (temporary sintering)

[0105] Within 1 minute after coating, the coated glass plate was put into an oven heated to 150° C. to dry for 1 hour, then placed in the oven, cooled to room temperature (25° C.) and temporarily cured.

[0106] (sintering)...

Embodiment 2

[0113] An antifouling structure was produced in the same manner as in Example 1 except that the condition of spin coating was changed to rotation speed: 1500 rpm.

Embodiment 3

[0115]An antifouling structure was produced in the same manner as in Example 1 except that the condition of spin coating was changed to rotation speed: 700 rpm.

Abstract

A soil-resistant structure according to the present invention is provided with a fine porous layer and a soil-resistant liquid on a base material. Further, the fine porous layer has a liquid retentionpart on a surface thereof, and has in an inner part thereof a liquid ejection part of which an affinity with the soil-resistant liquid is lower than that of the liquid retention part. The soil-resistant structure is characterized in that a film thickness of the liquid retention part is 1 / 100 to 1 / 50 of a film thickness T of the liquid ejection part.

Description

technical field [0001] The present invention relates to an antifouling structure having a microporous layer that holds an antifouling liquid, and more specifically, relates to an antifouling structure that has both the ability to hold an antifouling liquid and the ability to supply the antifouling liquid to the surface of the fine porous layer , and form an antifouling structure with a long-term self-healing antifouling surface and an auto part with the antifouling structure. Background technique [0002] Conventionally, there is known a configuration having a slippery surface with antifouling properties. [0003] For example, Patent Document 1 discloses a waterproof product retained by a fine porous layer of a waterproof material made of silica sol and fluororesin. Furthermore, the water-repellent product has excellent water-sliding properties (water-sliding properties) even after being irradiated with ultraviolet rays for a long time, or after the surface is worn.
