[0007]

Embodiments of the present invention will be described below based on one embodiment shown in the drawings. In FIGS. 1 to 3, dirt and the like on the indoor side surface of the window glass surface A spread in the vertical plane are removed, and a UV cut (ultraviolet ray cut off) is used as a coating liquid.
The liquid is put into the bottle 1 with a nozzle, the bottle is held in hand, the bottle is pressurized and dented by hand, and the liquid is gradually discharged from the nozzle 1d. Move the bottle towards the end.

As shown in FIG. 4, the bottle 1 with a nozzle for application is inserted into a transparent soft vinyl main body 1a through a lid 1b having an upper end opening, and a tube 1c is inserted into the main body 1a. Is slightly separated from the bottle bottom, and the part protruding from the lid 1b is the nozzle 1d. As shown in FIG. 5, the liquid recovery container 2 is obtained by cutting the bottle 1 of the tube 1c from the bottle 1 with the nozzle for coating. A survey scale 1e is provided on a side surface of the main body 1a. The nozzle diameter of the coating bottle 1 is 3 mm.
It is. The main body 1a is dented by the pressure of the hand held, and is restored by elasticity when the pressure is stopped.

Next, a coating operation as an embodiment of the coating method according to the present invention will be described. First, the window glass A, which is a painted surface, is cleaned as follows. (1) Removal of oil film When caulking is used in the attachment portion of the glass A to the window frame B, there is a possibility that an oil film or silicon may be attached.
The cm width portion is polished with an oil film remover (trade name; cleaner for automobile window glass of Wilson) to remove these. (2) Removal of dirt The entire glass surface is thoroughly cleaned with methanol, a waste cloth, a scraper, etc., and the methanol is completely wiped off with a waste cloth.

Next, masking and curing are performed as follows. (1) As shown in FIG. 6, as a masking adhesive tape on the lower end of the glass surface A, a cellophane tape 3 (cellophane is a registered trademark, and the manufacturer and seller is Sekisui Chemical Co., Ltd., address: 3-4 Toranomon, Minato-ku, Tokyo -7) Paste the thing of 8mm width,
Attach a 6 mm or 8 mm wide cellotape 3 to the upper end. (2) As shown in FIG. 6, a cellophane tape 3 having a width of 6 mm is attached to the left end and the right end of the glass surface. Paste the tape straight down from the top. The thickness of these cellophane tapes 3 is about 3 microns. (3) As shown in FIGS.
The upper part of the first curing sheet 4 (550 mm in width) is stuck to the boundary between the two. At this time, the left and right ends of the curing sheet 4 are cut off by about 30 cm beyond the window frame B and fixed firmly to the window frame B. The upper part of the surplus part is raised at the left and right ends, and the window frame B
Paste in. (4) As shown in FIGS. 7 and 9, a second curing sheet 5 similar to the first curing sheet is provided between the first curing sheet 4 and the cellophane tape 3.
The left and right ends are stuck up and doubled with the first and second curing sheets to prevent problems such as liquid leakage. (5) As shown in FIG. 10, a pull-up paper tape 6 is applied from the center to the outside of the cellophane tape 3 attached to the left end and the right end of the glass surface A from the top to the bottom, and the lower portion is cut longer by about 1 cm. Affix to the corners of the second curing sheets 4 and 5. (6) As shown in FIG. 11, both ends of the doubled curing sheets 4 and 5 are narrowed down and tied (or wound with paper tape). The lower portion of the pull-up paper tape 6 is adhered to the squeezed sheet portion, pulled upward, and firmly fixed to the window frame B, so that the tape does not peel off due to the weight of the liquid, thereby forming a liquid pool portion 4a.

Next, in order to improve the coating properties such as adhesion and durability of the coating, pretreatment is performed as follows. As an adhesive, New Primer (trade name, manufacturer and seller; address; 1-81, Soenmachi, Nakagawa-ku, Nagoya-shi, Aichi, name: Nichika Corporation), (chemical name; alcohol mixture, component name; organosilane, Use ethanol solvent). Prepare two dry and clean rags, one for the application, soak the New Primer in it, and apply it evenly to the glass surface so that there is no residual paint. Leave for 10 to 20 minutes, then lightly wipe with another rag.

Next, a coating liquid is prepared. As this liquid, UV and near-infrared cut liquid (ultra-green) (trade name;
UV cut K, manufacturer Address: 3-4-Benten, Minato-ku, Osaka
9, Name: Environmental Engineer Service Co., Ltd.) is used. Further, an accelerator (curing agent) (chemical name: alkoxysilane) is blended with the present liquid and used as a material for forming a coating film. The amount of the main solution is determined in advance according to the coating area, and correspondingly, bottle application 1 and collection bottle 2 are prepared. Then, the main solution is sucked by the collection bottle 2, and an accelerator is mixed with the main solution at a ratio of 3%, and is sufficiently vibrated to be mixed (for example, 300 cc of the main solution and 9 cc of the hardener).
Next, two layers of filter paper are layered on the funnel and transferred to the application bottle 1.

Then, as shown in FIGS. 1 to 3, the bottle is pressed and depressed by hand, and the liquid is gradually discharged from the nozzle 1d. The bottle is moved from one end (left) of the direction to the other end (right). The coating liquid flows down by gravity while partly adhering to the glass surface, and forms a uniform film. The excess liquid that has been applied and has flowed down into the liquid pool 4a of the curing sheet is immediately sucked by the recovery bottle 2, and the recovered liquid is filtered. After painting, dry carefully for about 20 minutes without blowing. At this time, care should be taken so that the insects and the curing sheet do not adhere to the painted surface. After natural drying, the masking sheet 3 and the curing sheet 4 and 5 are carefully removed so as not to adhere to the application surface. Estimated time for natural drying is about 2 in summer
It takes about 0 minutes and about 40 minutes in winter.

As described above, in the coating method of the present invention, a coating method completely different from the conventional coating method has been developed, for example, by applying a bottle for flowing, for example, a UV cut liquid directly to a glass surface. By applying pressure to the soft vinyl bottle by hand, the UV cut solution contained inside is continuously discharged in an appropriate amount to the upper corner of the glass surface through a thin nozzle, and allowed to flow down by gravity, thereby forming a film of the UV cut solution. Is to be generated.

By applying the masking tape of about 3 microns according to the above-mentioned embodiment, the UV cut liquid can be uniformly coated with a thickness of about 3 microns on a glass surface or the like. Very good coating was achieved with the liquid. As described above, by applying the UV cut coating, 99.8% of ultraviolet rays harmful to the human body can be cut off, and heat source energy of 2 to 4 ° C. can be saved (energy saving effect) for heating and cooling. In addition, various effects are exhibited, for example, it is possible to prevent the product and the interior of the room from being discolored by being irradiated with ultraviolet rays.

The film thickness is suitably in the range of 4 to 7 microns.
The thickness of the masking tape 3 is changed accordingly. The masking tape also has a function of covering the peripheral surface of the glass surface to which the caulk is attached. The ratio between the UV cut solution and the accelerator is based on 3%, but there is no problem in operation if it is in the range of 2 to 6%. As another example of the UV-cutting liquid, a trade name Ray Block (manufacturer address; 29 29, Iwaji, Fuyo-cho, Naruto-shi, Naruto-city, Tokushima Prefecture, name: Koei Ray Block, chemical name: methyl methacrylate) is used. The present invention can be applied to an inner surface of a glass surface inclined with respect to a vertical plane, such as a windshield of an automobile. The invention also applies to painting other than UV-cut painting and painting other smooth surfaces than glass surfaces, for example plastic surfaces.

The present invention is not limited to the examples and embodiments described above, but includes various modifications without departing from the spirit and scope of the appended claims.

[0018]

According to the present invention, a glass surface or the like can be easily
A uniform coating film (high quality) can be applied, and especially when a masking tape is used, the coating can be reliably applied with a uniform thickness. Then, it was possible to paint with the minimum necessary coating liquid. In addition, since anyone can engage in the painting work with a short training, the training period is shortened and the painting accuracy is dramatically improved. At the same time, the transparency of the painted glass surface could be increased. All the coating liquid that has flowed to the bottom can be collected and reused, so there is an effective use of resources and a very small amount of curing materials compared to conventional coating methods, which has the effect of reducing industrial waste generated after the completion of construction. .
