This invention relates to a method for forming a transparent conductive coating,
More specifically, the present invention relates to a method for forming a conductive coating film with excellent transparency on an object such as a thermoplastic synthetic resin plate. Thermoplastic synthetic resin boards coated with transparent conductive coating have excellent antistatic properties, so they are mainly used for semiconductor wafer storage containers, other electronic and electrical components, and construction materials such as window frames, wall materials, and flooring materials. It is used in parts for By the way, since transparent conductive paints generally contain conductive fine powder made of metal elements or their oxides, the resulting paint film tends to be cloudy, which reduces the transparency and color tone of the paint film. I was jealous that it would be damaged. Furthermore, due to its hygroscopicity, this coating film had a risk of decreasing its adhesion to the substrate and peeling off from the substrate. This invention was made in view of the above-mentioned circumstances, and while maintaining antistatic properties,
An object of the present invention is to provide a method for forming a transparent conductive coating film that can improve transparency and adhesion to a substrate. The coating film forming method according to the present invention involves applying a coating material mainly composed of a thermoplastic resin and conductive fine powder to an object and curing it, and then applying the same coating material to the object in order to form a cured coating film. After coating, the object having the coating film is heated under pressure. As the paint for forming the transparent conductive coating, known paints can be used as they are. Typical examples thereof include commercially available "transparent antistatic paint" (manufactured by Mitsubishi Metals Co., Ltd.) and those described in Japanese Patent Application Laid-open No. 85866/1983. As the constituent resin of the paint, any resin for general paints such as polyester, acrylic, polyvinyl chloride, and polycarbonate can be used. The conductive fine powder is a fine powder made of a metal element or its oxide, and in particular a white one whose optical refractive index is close to the optical refractive index of resin, 1.6 to 1.7, and whose fine powder diameter is 0.2μ or less. Fine powder is preferably used. Powder diameters exceeding 0.2μ are not preferable because they cause a lot of scattering of visible light and impair the transparency of the coating film. Application of the paint is carried out according to conventional methods. Typical examples thereof include a spray method, a roll coater method, a gravure printing method, and an offset printing method. The thickness of the coating film is approximately 0.5 to 20μ. The object to be coated is not particularly limited as long as it can withstand pressure and heating. In particular, plates, sheets, films, etc. made of transparent thermoplastic synthetic resin are often used. Examples of the resin include polyvinyl chloride resin, methacrylic resin, acrylonitrile-butadiene-styrene resin, polycarbonate resin, and the like. After coating, the object is heated under pressure using a conventional hot plate press, heated roll press, or the like. The pressurization and heating conditions are as follows. (a) Pressure = 5Kg/cm2 or more. If it is less than 5 kg/cm 2 , air bubbles mixed in the coating film will not be removed, and a uniform and smooth surface will not be obtained. However, even if the pressure is extremely high, the transparency will not be significantly improved, so the pressure is usually about 100 Kg/cm 2 or less. (b) Temperature = 60℃ or higher. At temperatures below 60°C, the cloudiness of the coating film hardly decreases. However, if the object to be coated is made of thermoplastic resin, the heating temperature is below its formation temperature. Therefore, the upper limit of the heating temperature range varies depending on the type of resin.
For example, when the object to be painted is a hard vinyl chloride sheet and a laminate is made from it,
If this is heated above the lamination press temperature of approximately 170°C, the resin will soften, making it impossible to obtain a laminated product of uniform thickness, and causing discoloration of the resin. Therefore, in this case, the heating temperature is about 170°C or less. As a result of the pressure and heat treatment according to the present invention, the haze of the coating film is significantly reduced. Although the reason for this is not certain, it is thought to be as follows. That is, since the coating film is based on a thermoplastic resin, heating it softens the coating film. When the coating film is pressurized in this state, the conductive fine powder present on the surface of the coating film is pushed into the softened coating film. As a result, the coating surface becomes uniform and smooth throughout, and haze is reduced.
The reason why the adhesion of the coating film is improved is thought to be that the coating film is dehumidified and degassed by pressurizing and heating the coating film. Next, some examples of this invention will be listed. However, all of these are illustrative and do not limit the invention. Example 1 Made of transparent polycarbonate resin, thickness 3.0 mm
``Transparent antistatic paint'' (product code: TEP-30) manufactured by Mitsubishi Metals Co., Ltd. was applied to one side of the substrate using a roll coater method to a thickness of 1.0 μm. The coated substrate is then left at room temperature for 1 hour to harden the coated layer.
A coating film was formed. In this way, a coated product A was obtained. Further, a coating film is formed on one side of the substrate using the same method as above, and then, as shown in FIG. A mirror plate protection film 15 is placed between the substrate 12 and the upper mirror plate 13. In this state, the coated substrate 12 was heated by a pair of upper and lower heating plates 16 and 17 at a pressure of 50 kg/cm 2 and a temperature of 100° C. for 10 minutes. In this way, a coated product (B) was obtained. For the above coated products (A) and (B), the haze, surface resistance value, and coating film adhesion were measured, respectively. The results are shown in Table 1.

Example 2 A coating film was formed on a substrate in the same manner as in Example 1, except that a transparent polyvinyl chloride resin plate was used as the substrate instead of a transparent polycarbonate resin plate. Further, the above operation was repeated while variously changing the pressurizing and heating conditions. The haze and surface resistance values of the obtained coated products were measured. The results are shown in Table 2.

Demonstrated transparency. Example 3 A coating film was formed on one side of a 0.05 mm thick film made of transparent polyvinyl chloride resin by the same method as in Example 1. Next, as shown in FIG. 2, the film 22 is placed between the pair of upper and lower mirror plates 23 and 24 with the coating film 21 facing upward, and the mirror protection film 25 is placed between the film 22 and the upper mirror plate 23. At the same time, 286 sheets of transparent polyvinyl chloride resin having a thickness of 0.5 mm were placed between the film 22 and the lower mirror plate 24. In this state, the coated film was heated by a pair of upper and lower heating plates 26 and 27 at a pressure of 30 kg/cm 2 and a temperature of 170° C. for 10 minutes.
In this way, a coated laminate product (C) with a thickness of 3.0 mm was obtained. For comparison, we also show an adhesive laminated product (D) in which six of the above sheets are simply laminated to the above film, and a painted adhesive product in which a coating film is formed on this adhesive laminated product (D) using the same method as above. A laminated product (E) was manufactured. The haze and surface resistance values of these laminated products (C), (D), and (E) were measured, respectively. The results are shown in Table 3.

Example 4 In FIG. 3, a rolled film 31 made of transparent polyvinyl chloride resin and having a thickness of 0.05 mm was passed between a pair of upper and lower coating rolls 32 and 33 to form a coating film 34 on the upper surface of the film 31. Next, the film 31 was passed between a pair of upper and lower heaters 35, 36, and then between a pair of upper and lower pressure rolls 37, 38 to heat and press the coated film. In this way, a coated product (F) was obtained. Example 5 A coating film was formed on one side of a 0.05 mm thick strip film made of transparent polyvinyl chloride resin by the same method as in Example 1, and the film was wound into a roll. Next, as shown in FIG. 4, the film 43 with the coating film 42 pulled out from the roll 41 and the sheet 45 with a thickness of 0.5 mm made of heated transparent polyvinyl chloride resin extruded from the extrusion device 44 are placed in the film 43. Stack the sheets 45 on the non-painted surface of the top, middle and bottom gloss rolls 46, 47, 4.
Passed between 8 and 8. In this way, a painted laminated product (G) was obtained. As described above, according to the coating film forming method of the present invention, a coating material mainly composed of a thermoplastic resin and a conductive fine powder is applied to an object and cured, and then the object having the cured coating film is coated. Since the heating is carried out under pressure, it is possible to reduce the cloudiness of the coating film while maintaining the antistatic properties of the coating film, and to improve the adhesion of the coating film. Therefore, according to the present invention, it is possible to form a coating film that does not lose its transparency and color tone and is free from the risk of peeling over a long period of time.
