BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flow chart for explaining a method of constructing a glazing film for an automobile window glass according to the present invention, and FIG. 2 is a flowchart for explaining an embodiment where a glazing film is already installed in a window glass.

Referring to FIG. 1, a method of manufacturing a tinting film for an automobile window glass according to an embodiment of the present invention includes a preparation preparation step S00, a window glass cleaning step S10, a film cutting / molding step S20, (S30), a film care step (S40), and a job end (S50).

In the work preparation step (S00), the preparations (the concrete preparations will be described later) such as tools and solutions necessary for each step are arranged at appropriate positions, and the workplace and the work vehicle are set in the optimum state for the work For example, a cover may be put on a seat in a vehicle, or a drop close may be placed under the construction part to prevent contamination of the vehicle due to construction or to separate and remove the room mirror, .

As will be described later, in the case of a windshield (WIND SHIELD) and a rear glass (REAR GLASS), a work of cutting a turning film in the machine direction for one work is performed in a work preparation step (S00) A tanning film is prepared.

In addition, in the case of the front door and rear door glass (FRT & RR DOOR GLASS), a tinting film to be constructed is prepared using a semi-pattern having the shape of the window glass to be worked.

FIG. 2 is an example of a case where a glazing film already applied to a window glass is present. In addition to the operation preparation step of FIG. 1, a window film removal process in which an operation of removing a previously- / Job preparation (S00 ') is performed.

One embodiment of the window film removing operation of the present invention will be described.

In the case of the first adhesive agent, the ammonia component penetrates into the bond, which is an adhesive between the glass and the film, to cause a chemical reaction due to radiant heat to soften the bond, and the film is easily removed when the film is removed by swelling do. The second adhesive agent may contain an ethylene glycol component as an essential component, and the ethylene component may be used as a film adhesive to soften the bond component, thereby facilitating the removal of the bond. In the case of removing the film, Lt; / RTI >

      [Sweating method]

Sweeting is the easiest way to remove old adhesive, glass with hot-melt glass, and reduces the risk of scratching and trouble. It is suitable when the outside temperature is over 15 degrees. (Silver film is used when cold weather is cold, because it emits sunlight to heat the glass.

       A. Clear, warm and sunny days

1. Prepare a large black plastic garbage bag.

2. Cover the glass with a garbage bag outside the glass and cut to fit the shape of the window to cover the entire film surface when placed inside the glass.

3. Spray the first adhesive removal solution onto the interior surface of the window.

4. Place the black garbage bag over the wetted inner surface of the sprayed window so there is no exposed film.

5. Place the vehicle in a location where the glass can best receive sunlight.

6. Wait for about 30 minutes to allow the first adhesive remover solution to soak into the film. At this time, close the car door to minimize the evaporation of the solution and maintain the maximum temperature. In the case of metallic films, it takes about 2 hours to immerse the first debonder remover empirically and spray the debonder remover every 20 minutes to avoid evaporation of the solution.

7. Using a nail or razor blade, make sure that the edge of the film is easily removed from the glass surface. If it easily peels off, hold the film together with the waste bag removed and slowly pull it down diagonally. If you do not remove the garbage bag first, the moisture will not evaporate and the temperature will be maintained to smooth the adhesive.

8. If the film does not peel off from the glass surface, spray the adhesive remover solution again, cover the garbage bag and retest after 30 minutes.

9. Repeat as needed until the film easily falls off the glass surface.

      10. Leave remaining adhesive on the glass by spraying a second removal solution and rubbing it off with a scratch-free nylon pad on the glass. Using a cleaning rubber squeegee, wipe off the gluing agent solution, re-spray the adhesive removal solution, and wipe the remaining adhesive, especially the adhesive remaining on the hot wire section, with a steel wool.

B. Cloudy and rainy days

      It is necessary to cover black vinyl after 1 ~ 4 steps and to sleep overnight, and it is necessary to adjust the room temperature of the workplace to facilitate the penetration of adhesive removal solution for a long time.

[Steaming method]

The steaming method is a method of using a steamer for generating and discharging heated steam. Especially, it is used after a bad weather such as a cloudy day and a rainy day.

1. Start at the end edge of the glass with the film attached and heat the steamer head forward and backward at a time, about 1 to 2 square feet of the film area at a time. At this time, it does not exceed 10 inches. In the case of side windows, divide by half.

2. Use a razor blade or a nail to slightly lift up the end of the film with a new blade, then heat the steamer and slowly peel it off.

3. After the film is removed, the remaining adhesive is sprayed with the second adhesive remover solution and wiped off with a nylon pad, steel wool, cross-cut blade or scraper.

Here, in the case of the front glass, since the laminated glass is not a tempered glass like a side glass, the strength of the glass is low, so it is necessary to pay attention when using the steamer, and the water accumulated in the steamer hose must be discharged periodically to smoothly flow the steam.

The window glass cleaning step S10 is a step of cleaning the window glass to be worked by using a glass cleaning solution for removing the oil film on the surface of the window glass to be worked.

In this embodiment, a glass cleaning solution containing 85 to 90% by weight of distilled water and 10 to 15% by weight of glass cleaner is prepared and used as the glass cleaning solution. The glass cleaner is composed of 95 to 99% by weight of demineralized water, A mixed solution of PH 1.5 to 2.5 mixed with a mixture of 1 to 5% by weight of synthetic resin of epoxy resin, epoxy resin, epoxy resin, and ethanol is prepared and used. Thus, the oil film formed by organic matter (wax / dead insect / The use of a glass cleaning solution or a glass cleaner having a characteristic component and mixing ratio of the present embodiment effectively removes invisible oil residues and impurities on the glass surface, By making the glass adhesion surface even, the adhesion of the glazing film to the glass surface is improved, and the adhesion of the back film It is possible to prevent lifting or peeling.

The window glass cleaning step S10 may be performed before the film cutting / molding step S20 and the film attaching step S30, and the window glass to be worked may be the front door and the rear door glass (FRT & RR DOOR GLASS) (WIND SHIELD) and a rear glass (REAR GLASS) can be performed during each work process of the film cutting / molding step (S20) and the film attaching step (S30) (This will be described in detail in connection with the cutting / molding step and the film attaching step) in the film attaching step S30.

The film cutting / molding step S20 is a step of molding the tinting film according to the shape of the window glass to be worked. The tinting film and the preparation material to be prepared in the preparation step S00 are used. ) Is a process of attaching a tanning film to a window glass to be worked by using a film-forming solution for attaching the tanning film to the window glass.

In the embodiment of the film cutting / forming step S20, the same film-applying solution as that of the film-forming solution for attaching the glazing film used in the film-attaching step S30 to the window glass may be used, This is a characteristic film-forming solution used in the film-attaching step (S30) of the present invention, in which a film-coating solution containing 85 to 90% by weight of distilled water and 10 to 15% 10% to 20% by weight of sorbitan laurate, and 1% to 5% by weight of sodium trideche sulphate, so that no chemical change with respect to the film main component (adhesive and coating agent) The addition of the sodium component accelerates the natural hardening of the remaining water after the application of solar energy, and the fact that the surfactant sorbitan laurate is easy to mount or position in the process of calibration Gender is due.

In the film cutting / molding step S20 and the film attaching step S30, different processes are applied depending on the type of the window glass to be worked.

If the window glass to be worked on is windshield (WIND SHIELD) or rear glass (REAR GLASS), the process will be explained first.

3 is an explanatory view of a main operation for explaining a process of a film cutting / forming step S20 and a film attaching step S30 in the case of a window glass to be worked is a windshield (WIND SHIELD) and a rear glass (REAR GLASS) . Referring to FIG. 3, a siding film cut / cut in a machine direction at an appropriate size in a work preparation step S00 for one sheet construction is formed into a single film on a work window glass by a heat forming method Shaped.

The tanning film has a texture or a direction like a fabric fabric, as shown in Fig. 3A. The texture formed through the machine during the production process is referred to as the machine direction. Tanning films are slightly stretched by tension in the machine direction during the production process. However, the stretched film has a memory of the original shape before the stretching of the film, and the film shrinks due to the nature of returning to its original shape when the heat is applied. Heat-shaping is performed by using heat-shrinkable nature of such a film, and can be roughly divided into wet forming and dry forming. According to the embodiment, either one of wet forming and dry forming may be used or a mixing method may be used as follows.

 In case of wet forming process, heat gun, bulletproof gloves, hard card, cutting knife, construction solution, channel squeegee, rubber squeegee and cutting knife are prepared S00), the following operations are performed.

1. Spray application solution on external glass surface and wipe clean.

2. Spray the construction solution back onto the glass surface.

3. Place the film cut in the machine direction with the liner facing upwards, so that the maximum length is horizontally aligned with the shape of the work glass.

4. Overall, cut along the edge of the glass about 2cm from the end of the ceramic.

5. Use a hard card to hold the film in a horizontal direction, that is, in an "H" shape, on both sides of the side edge and the middle of the glass.

6. Adjust the size of the flat film evenly by dividing the remaining finger parts without touching the curved glass.

7. The temperature of the heat gun is set to 300 degrees for ordinary film and 305 to 450 degrees for laminated metal film and keep the interval of about 20 to 25 cm from the film surface so that the heat gun is shaken to the left and right, The shrinkage proceeds (see Figs. 3B and 3C)

8. If the size of the finger is excessive, it shrinks from the edge of the film to the center of the film from the outer side to the center. By preventing the excessive heat from being concentrated by inserting the heat into the finger portion, the stress of the film caused by heat is minimized, Use contraction techniques.

9. It is important to move the fingers, which are the remaining part of the film, gradually to the side while adjusting them, and it is also important to practice the distance between the heat gun and the film surface in advance for effective shrinking. This distance may vary depending on the selected temperature setting.

10. Continue the same process by holding the hand until the excess film, the large finger, is converted to a small shape and moving sideways. When the size of the finger is greatly reduced, the finger portion is finally pressed using a cloth card. It should be noted here that the thin film below the film makes it easy to shrink the extra film.

11. Once all the excess film is in contact with the glass, the film is ready for installation.

When dry forming is done through the process, the film cut and cut in the machine direction and the preparation materials such as heat gun, bulletproof gloves, hard card, cutting knife, construction solution, channel squeegee, rubber squeegee, cutting knife, baby powder, A paper soap (fabric softener) is prepared in the preparation step (S00), and the following operations are performed.

         "Dry shrinkage" is a superior technology that is much faster than wet shrinkage and less product deformation. Drying shrinkage should be done carefully because the tanning film reacts very quickly to heat. As the name suggests, "dry shrinkage" is achieved without the use of a solution under the film, unlike wet shrinkage. Because the heat spreads down to a large area under the film, it is very advantageous to shrink. In addition, when the foam is completed due to dry shrinkage, the refractive index and shape of the glass are matched, and the shape of the product is long since it has a continuous shape.

1. Spray application solution on external glass surface and wipe clean.

2. Dry the glass thoroughly.

3. Spray baby powder on glass. The reason is that the anti-scratch coating film surface is not adhered to the glass surface during the thermoforming process. If you use paper soap instead of baby powder, moisten it with water and apply it to the glass and dry it with dry heat.

4. Using a wet towel, wipe the top and bottom edges of the glass in the horizontal and vertical directions with an H-shape, place the cut film on the glass with the liner up and the maximum length horizontally, To prevent it from moving.

5. Overall, cut along the edge of the glass about 2 cm from the end of the ceramic.

6. The temperature of the heat gun is set to 300 degrees for ordinary film and 350 to 450 degrees for laminated metal film and maintain a gap of about 15 to 30 cm from the film surface.

7. The film is largely divided into four equal parts, and the heat gun shakes from side to side, and from the center to the outside, from left to right, shrinks toward the fingers. Dry shrinkage does not require the use of a hand or tool to press the film.

8. When complete molding is complete, lift the film, spray the solution onto the glass, and place the film in place.

9. Spray the film on the film surface and carefully drain it with a rubber squeegee.

10. Shrink the film in the same manner as the wet method using a dry gun and a heat gun.

11. After film shrinking, use a knife to cut about 5mm larger than the glass edge. The knife used for the cutting is a rotary knife or a cutting knife. The rotary knife has a characteristic that it does not scratch the glass surface. Even when using a cutter knife, it is possible to use a button or a pet piece so that there is no direct contact with the glass surface, The line is drawn and cut to prevent scratches on the glass (see Figure 3d).

The film attaching step S30 is a step of attaching a film to the workpiece to be worked on a windshield WIND SHIELD and a REAR GLASS to form one sheet of a tanning film formed in the film cutting / Film, heat gun, hard card, construction solution, cleaning solution, channel squeegee, rubber squeegee, drop close and seat cover are prepared at the preparation stage and the following operations are carried out.

As the cleaning solution, the glass cleaning solution used in the embodiment of the window glass cleaning step (S10) may be used as it is.

A film-forming solution containing 85 to 90% by weight of distilled water and 10 to 15% by weight of a film-adhered film is prepared and used as a film-forming solution. The mixed film-adherend is composed of 75 to 89% of desalted water, 10 to 20% by weight and sodium trideceth sulfate in an amount of 1 to 5% by weight based on 100 parts by weight of the total weight of the composition. Thus, the present invention is free from chemical changes with respect to the film main component (adhesive and coating agent) Of the sodium component promotes the natural hardening by the solar heat of the residual water after the application and the surfactant ingredient sorbitan laurate becomes effective in the mounting or positional correction in the process of operation.

1. Move the film after the heat-forming (shrinking) to the cut, and clean the outer glass once again with the construction solution.

2. Cover the driver's seat and backstage seat cover with a drop-closed underneath the film.

3. Separate and remove the room mirror, A-pillars, other fixtures, and electrical parts such as cradles for clean construction.

4. After spraying the cleaning solution on the glass to be attached, wipe out the impurities and grease on the glass with nylon pad. Clean it twice in the same way.

For reference, the jobs 2 to 4 may be omitted when they are performed in the preparation preparation step S00 and the window glass cleaning step S10, respectively, and may be performed additionally if necessary, And may be carried out in the film adhering step, which is not performed in the job preparation step S00 and the window glass cleaning step S10, as the selection is made.

5. Peel off the liner of the film to attach the cut film. As a method for removing the liner, there is a method in which the film is wound around the end of the wet backside (after separating the film liner and spraying the solution onto the adhesive surface, covering the liner again) (see Figs. 3E to 3G) (It is advantageous when there is a device or an obstacle in the middle of a backlight or a room mirror, for example, by cutting the liner which has been hung from the both ends of the film, And a dry back end method may be used. In the end of the film for construction, it should be rolled from the opposite side of the direction to be applied, and it should be tight so that the film can be prevented from being bent or film scratched when the film is released.

6. Take the film wound on the cleaned glass 5 times, spray the solution on the glass, loosen the film about 70cm, place it on one side of the glass, gently fix it with one hand, Untied and seated.

7. After positioning, spray the application solution onto the film surface for a smooth squeegee, then push the water outwards from the center to the crosshair using a rubber squeegee.

8. Use a long handled squeegee to drain the edge of the glass.
