Problems solved by technology

[0007] However, when such a coating is installed outdoors, there is a problem that although it has a good anti-ice and snow effect at the initial stage of installation, after several weeks after installation, due to the adhesion of pollutants on the outside of the coating and the aging of the coating film itself, it will be damaged. Decreased hydrophobic performance, loses anti-ice and snow effect
In addition, in order to form a surface with a certain degree of smoothness, it is necessary to mix fine particles in the paint, etc., and there are various problems such as difficult handling during coating and short pot life of the paint.
In addition, such a process is complicated and the cost is very high.

Embodiment 8、 comparative example 3 and comparative example 6，100mm×100mm、1.5mm or 。 other Embodiment and comparative example ，100mm×100mm、3.0mm、()。 Embodiment 1

[0078] X-24-9270 (manufactured by Shin-Etsu Chemical Co., Ltd.), which is a fluorosilicone coating agent, was diluted to a solid content ratio of about 2.0% to prepare a coating liquid for a hydrophobic membrane. Then, the polycarbonate plate was dipped in the coating solution tank for the hydrophobic film, lifted at a speed of about 5 mm / min, dried at room temperature, and then heat-treated at about 80° C. for about 30 minutes to obtain the coating of Example 1. [Example 2]

Embodiment 2

[0079] Except diluting X-24-7890 (manufactured by Shin-Etsu Chemical Co., Ltd.), which is a fluorosilicone coating agent, to a solid content ratio of about 1.0%, to obtain a coating solution for a hydrophobic membrane, this product was prepared in the same manner as in Example 1. Covering of Example 2. [Example 3]

Embodiment 3

[0080] Use octadecyltriethoxysilane (ODTES), that is, a coating solution with LS6970 (manufactured by Shin-Etsu Chemical Industry Co., Ltd.) as the main component, so that the mixing ratio of the coating solution for the hydrophobic film is C 18 h 37 Si(OC 2 h 5 ) 3 : Ethanol [EtOH] : Water [0.01N, HNO 3 ] = about 1:150:8, stirred at room temperature for 5 hours, and used as a coating liquid for a hydrophobic membrane. Then, in an ambient atmosphere with a relative humidity below about 10%, immerse the polycarbonate plate in the coating solution tank for the hydrophobic film, lift it up at a lifting speed of about 10mm / min, dry it at room temperature, and then heat-treat it at about 60°C In about 30 minutes, the coating of Example 3 was produced. [Example 4]

Abstract

A covering has a property of allowing an accretion of snow to slide and comprises a coating layer formed on a surface of a substrate in order to prevent accretion of snow and ice. As for the coating layer, its external surface has such wettability that a contact angle relative to water is 70 degrees or greater, and also has such water sliding property that a waterdrop sliding angle is 40 degrees or less. Alternatively, the external surface of the coating layer has such water repellency that a surface tension is 35 dyne / cm or less, and also has such water sliding property that a waterdrop sliding angle is 40 degrees or less.

Description

technical field [0001] The present invention relates to structures that prevent snow from accumulating in cold areas, such as road safety structures such as signal machines, road signs, sight guidance signs, sound insulation walls, and protective barriers, building structures such as roofs, exterior walls, and fences, and telecommunications Ice and snow sliding coverings for structures exposed to snow or ice outdoors such as facilities for accumulating ice and snow. Background technique [0002] Ice and snow that occur in snow-covered cold areas generally bring various disasters and failures to life or industrial activities. For example, when there is snow on the wires, the wires break or the tower poles collapse, etc., causing large-scale power outages. In addition, the snow rolled up during the running of the train adheres to the pantograph or under the vehicle and sometimes causes obstacles to the running of the train. In addition, where it is involved in knowing the ex...
