[Industrial Application Field] The present invention is applicable to sports such as swimming and skiing, dust,
This invention relates to an anti-fog processing method for goggles used to protect eyes in environments such as toxic gases and explosions. [Prior Art] In recent years, swimming has become popular at beaches, pools, etc. for the purpose of promoting health. In particular, indoor pools are now heated and can be used for swimming all year round. However, as the water temperature rises, the amount of disinfectant used also increases, which can damage the eyes, so the use of goggles, that is, underwater glasses, has become essential. Furthermore, goggles are commonly used in winter sports such as skiing or skating to protect the eyes from snow, strong winds, etc., and also to protect the eyes in work environments where dust, toxic gas, explosions, etc. are present. However, the inner surface of the goggles mentioned above is hydrophobic, so if there is a temperature difference with the outer surface, the inner surface will become cloudy.
There is a fatal drawback that it is easy to cause. Several anti-fog techniques have been proposed to solve this drawback. Conventional anti-fog processing methods include, first, a method of forming a coating film with a hydrophilic transparent liquid polymer substance on the inner lens surface of goggles (Utility Model Application Publication No. 122238/1989);
Second, a method in which an acetylcellulose resin plate of a size corresponding to the lens surface is saponified with caustic soda solution to prevent fogging only on the inner lens surface of the goggles molded with polycarbonate resin, and then fitted. A third method is to attach an acetyl cellulose film to the inside of goggles made of polycarbonate resin using an adhesive. [Problems to be Solved by the Invention] However, the first method for forming a coated film surface of a hydrophilic transparent liquid polymer substance on the lens surface of the goggles is difficult to use when the polymer substance is water-soluble such as polyethylene glycol or polypropylene glycol. Because it is a polymer, if moisture adheres to the lens surface, the polymer substance tends to dissolve and flow down the lens surface. To prevent this, it is necessary to roughen the lens surface in advance to maintain the coating film. There is. This required complicated plastic processing to make the lens surface rough, and there was a problem in that the image seen through the goggles was likely to be distorted. In addition, the method of fitting the second acetyl cellulose resin board has the following problems: the base material used is limited to acetyl cellulose resin, the saponified surface is unstable and the antifogging effect is extremely short-lived, and the problem is that if it absorbs moisture, There were problems such as distortion and deformation of the image in the field of view, the resin plate coming off during use of the goggles, and fogging on the inner surface of the goggles other than the lens surface, narrowing the field of view. Furthermore, in the third method of attaching acetyl cellulose film, peeling of the film is often observed due to uneven adhesion, and, like the second method, clouding occurs on the inner surface of the goggles other than the lens surface, impairing the field of view. There was a problem that hindered this. In recent years, risk prevention has become an important theme in sports, and strong resin products such as polycarbonate and acrylic have become commercially available, but there are anti-fog treatments for these resin products that eliminate the above problems. There is no law in sight. The purpose of the present invention is to solve the various problems of the conventional anti-fog processing methods described above. It is unnecessary to roughen the lens surface before processing, and distortion of the image of the field of vision does not occur. By firmly adhering the anti-fog film not only to the lens surface but also to the entire inner surface of the goggles, the anti-fog film will not dissolve even if moisture adheres to it, resulting in a permanent anti-fog effect. An object of the present invention is to provide an anti-fog processing method for goggles, which provides an anti-fog film with good water absorption properties because it contains an activator. [Means for Solving the Problems] The structure of the present invention for achieving the above object is described in the first aspect.
This will be explained based on the diagram and FIG. In both figures, goggles 1 are goggles molded from various transparent plastics such as polycarbonate, polyester, polymethyl methacrylate, acetylcellulose, polystyrene, acrylonitrile styrene, acrylonitrile butadiene styrene, and the like. An antifogging film 3 of uniform thickness containing a water-insoluble polymer having a hydrophilic group and a surfactant is formed on the entire smooth inner surface 2 of the goggles 1. The goggle inner surface 2 has a concave shape and consists of a lens surface 2a and a cover surface 2b provided around the lens surface. The anti-fog film 3 is made of a water-insoluble polymer such as a liquid acrylic-based, fluorine-based, or polyurethane-based hydrophilic polymer, which improves the wettability of this polymer to the goggles 1, and improves the water absorption after the anti-fog film is formed. After coating the lens surface 2a and the cover surface 2b with a mixture of a surfactant and a surfactant to improve the temperature, heat the mixture at a temperature of 100 to 150°C for 10 to 15 minutes. It dries and forms immediately. Examples of water-insoluble polymers include acrylic resins, fluorine resins,
Polyurethane resin or the like is used. Further, as the surfactant, anionic or nonionic surfactants can be used. The surfactant is mixed in an amount of 1 to 5 parts by weight per 100 parts by weight of the water-insoluble polymer. If it is less than 1 part by weight, the wettability of the polymer to the goggles 1 and the water absorption after forming the anti-fog film will be poor, and if it exceeds 5 parts by weight, the adhesive strength of the anti-fog film 3 will be reduced. This water-insoluble polymer has goggles 1 after heating.
In order to further improve the adhesion with the material, a small amount of epoxy resin or urethane resin may be added as an adhesive. By the heating, the liquid polymer forms a crosslinked structure on the inner surface 2 of the goggles and hardens in close contact with the inner surface 2 of the goggles. At the same time, the hydrophilic groups in the polymer are arranged on the membrane surface. [Function] In the goggles 1 having such a structure, the hydrophilic groups in the water-insoluble polymer are arranged on the surface of the antifogging film 3, so that the inner surface 2 of the goggles becomes hydrophilic. Furthermore, the presence of the surfactant improves the water absorbency of the inner surface 2 of the goggles. As a result, even if the inner surface 2 of the goggles 1 falls below the dew point temperature, the moisture in the air inside the goggles 1 does not turn into minute water droplets, and fogging does not occur. In addition, since the anti-fog film 3 has a crosslinked structure made by heating a water-insoluble polymer, it firmly adheres to the entire inner surface 2 of the goggles 1, has no stickiness to the touch, has excellent durability, and has an extremely thin and uniform thickness. Since the anti-fog film 3 is formed on the inside of the goggles, the presence of the anti-fog film 3 cannot be seen with the naked eye, and since the anti-fog film is formed on the smooth inner surface of the goggles, the image of the field of view through the goggles 1 is not distorted. [Effects of the Invention] As described above, according to the anti-fog processing method for goggles of the present invention, an anti-fog film is formed on the entire inner surface of the goggles, so that unlike conventional methods, areas other than the lens surface do not become foggy. Good field of view can be obtained. In addition, the cross-linked structure of the water-insoluble polymer firmly adheres the anti-fog film to the smooth inner surface of the goggles without making the lens surface rough, resulting in a long-lasting anti-fog effect with high abrasion resistance. . [Example] Next, an example of the present invention will be described together with a comparative example. <Example> A liquid is prepared by uniformly mixing 3 parts by weight of an anionic surfactant with 100 parts by weight of an acrylic hydrophilic polymer. Apply this mixture to the smooth lens surface 2 of goggles 1 made of transparent polycarbonate resin.
The antifogging film 3 was formed by applying the anti-fogging film 3 to a uniform thickness on both the smooth cover surface 2b and heating the film at 120° C. for 10 minutes. The thickness of the anti-fog film 3 after heating is approximately 2μ
It was m. <Comparative example> A 1.0 mm thick acetyl cellulose resin plate, which has a size equivalent to the inner lens surface of goggles molded from polycarbonate resin, was immersed in a 5% caustic soda solution for 60 minutes, and the surface was saponified. A water-absorbing thin film was formed on its surface. This anti-fogging acetyl cellulose resin plate was fitted into the lens surface of the goggles. <Test details and results> (1) The following tests were conducted for the examples, and appearance, adhesive strength, and breath tests were conducted on an hourly or cycle basis. The results are shown in Table 1. To check the adhesive strength, use a safety razor to
After cutting a total of 25 squares (5 x 5) with a scale of several mm, adhesive adhesive tape is pasted on the surface of the anti-fog film 3, and when the adhesive tape is peeled off, the anti-fog film 3 is peeled off. This was done using a tape test to check the number of stitches. (a) Heat resistance: Left in a hot air dryer at 100°C for 100 hours. (b) Heat cycle: The temperature was maintained at -20°C for 2 hours, then the temperature was raised to 80°C in 1 hour, the temperature was maintained at 80°C for 2 hours, and then the temperature was lowered to -20°C in 1 hour.
One cycle was a 6-hour thermal history between -20°C and 80°C. (c) Hot water resistance: Immersed in hot water at 75℃. (2) Regarding Examples and Comparative Examples, (d) Normal antifogging property, (e)
A breath test and a steam test were conducted for water resistance and (f) heat resistance, respectively. The results are shown in Table 2. From Table 1, the goggles of the examples showed excellent anti-fogging effects in terms of (a) heat resistance, (b) heat cycle, and (c) hot water resistance under the conditions shown in the table. In addition, in a tape test showing adhesive strength, all 25 stitches remained.
