The present invention relates to a method for restoring a transparent plastic material and a restoring agent, and more particularly, to a method of restoring a surface of a contaminated transparent plastic material to a transparent state such as the first through polishing and polishing.

The plastic of transparent material is contaminated due to the minute scratches and the adsorption of foreign substances on the outer surface and becomes opaque, and thus the transparent original plastic cannot be maintained.

The use of the plastic material as described above is applied to a variety of applications, such as home or office as well as the general industrial field, and in the case of the headlights for automobiles, the plastic of transparent material is used.

In particular, in the case of the headlight (1) is applied to the car, as shown in Figure 4, when the first shipment, the headlight has a clear and transparent state, so that the light is smoothly illuminated at night driving to secure a sufficient front clock to drive safely This becomes possible.

However, as time passes, it is exposed to sunlight and the surface is damaged by the foreign matters as well as the opaque state due to the adsorption of foreign matters. There is a high risk of safety accidents.

While driving at night, they are exposed to the risk of safety accidents due to poor visibility of the front watch, but in the daytime when the headlights are not used, the aesthetics of the whole car are harmed by the contaminated headlights as opposed to the clean body.

As such, headlights with a lifespan shorter than the life of the car are currently in a state where it is impossible to regenerate and restore them, so they need to be replaced with new ones frequently. There is a problem.

In addition to the automotive headlights mentioned above, the same problems occur in various products and applications such as the surface of prefabricated panels and the painted parts of automobiles, as well as transparent plastic products exposed to sunlight and the outside for a long time. Many problems caused by this situation are occurring.

Therefore, the present invention has been invented to solve the above problems, providing a method for restoring the contaminated surface of the transparent plastic product to the clear and transparent state as the initial state, as well as providing ease of maintenance, new Its purpose is to reduce economic costs since it does not have to be exchanged for one.

Looking at the preferred restoration method of the present invention for achieving the above object with reference to the accompanying drawings as follows.

1 is a process block diagram showing a process of restoring a transparent plastic material to which the technique of the present invention is applied, FIG. 2 is a photograph showing a headlight for an automobile as an example of a transparent plastic material restored according to the present invention, and FIG. Will be described together as a photograph showing the comparison between the restored vehicle headlight and the unrestored automobile headlight.

Looking at the restoration process 100 of the transparent plastic material to which the technology of the present invention is applied, by using the sandpaper 1000 with water and evenly rub the surface of the transparent plastic material to be restored 1 Car surface removal step 110 is performed.

After the first surface removal step 110 is completed by using a sandpaper No. 1500 with a small amount of water evenly rubbed the surface of the transparent plastic material to be restored in the first surface removal step (110) A secondary surface removal step 120 is performed.

After the second surface removal step 120, the compound is evenly applied to the surface of the plastic material to be restored 2000 times, and then low rotation (50 to 1500 rpm) using a polisher commonly used for polishing, surface polishing, etc. In step 1, the surface is evenly polished to perform the polishing step 130 for polishing the rough surface in the first and second surface removal step (110,120).

After the polishing step 130 is finished, the restoration agent is evenly applied to the surface of the plastic material, and then polished evenly using a polisher to polish the surface of the plastic material while preventing the damage caused by foreign substances while maintaining the gloss state for a long time. Complete through the coating step 140 to perform the coating to be able to.

The restoring agent used in the coating step 140 uses a thick gel-type compound that is mixed with compound No. 3000 and olive oil, and the mixing ratio of compound No. 3000 and olive oil may be mixed in a ratio of 7: 3 as a result of several experiments. When the gloss and coating appeared to be excellent.

Of course, the mixing ratio of the compound No. 3000 and the olive oil may consider an error range of ± 10% at a ratio of 7: 3, but the most preferable mixing ratio is 7: 3.

In the case of the compound No. 3000 and the olive oil, the restoring agent is composed of components such as isoparaffin, idrocarbon, and aluminum oxide to perform surface polishing and some gloss, with moisturizing effect and heat resistant coating effect. It is possible to coat the surface of the regenerated plastic material by the characteristic of olive oil having the effect of blocking the penetration of foreign substances such as dust and tar.

Looking at the embodiment using the same process and the restorer,

Example.

At the end of its life, the scrapped and heavily polluted surface of Kia Motors' Credos headlights was evenly rubbed using sandpaper # 1000 to remove dirt and damage from the surface.

In this process, sandpaper was soaked in water or sandpaper was used to periodically rub the surface of the headlight to increase the efficiency of polishing.

Immediately after the first surface removal step 110 as described above, by using the sandpaper No. 1500, evenly rub the surface of the headlight to remove the foreign matter and wounds that could not be removed, as well as to obtain the effect of evenly polishing the surface The second surface removal step 120 is performed.

In this process, it is also preferable to use a smaller amount of water than the amount of water used in the first surface removal step 110 to use water.

After the second surface removal step 120 is completed, remove the fine substances or water on the surface of the headlight, and then apply the No. 2000 evenly to the surface of the headlight. Burn the compound to the surface of the headlight.

In this process, the polishing is mechanically performed by the polisher to completely remove the fine damage generated by the sandpaper in the second surface removing step, thereby smoothly polishing the surface of the headlight.

After polishing the surface of the headlight as described above, compound No. 3,000 and olive oil 3 are mixed and evenly applied to the surface of the headlight with a thickening agent provided evenly on the surface of the headlight. Polish.

Then, the surface of the headlights is polished by a restoring agent having the properties of the compound and the olive oil evenly, and the surface of the polished headlights is coated to cause infiltration of moisture, adsorption of foreign substances, or minute scratches. Will be prevented.

The headlights restored by the above-described embodiment are maintained as if they are new as shown in FIG. 2, and can also be seen in the comparison pictures of the restored headlights and the unrestored headlights as shown in FIG. 3. As you can see, there are obvious differences.

As described above, the present invention provides a method for restoring the contaminated surface of the transparent plastic product to a clear and transparent state as in the initial state, thereby providing ease of maintenance and economical cost because it does not have to be replaced with a new one. It is the invention which has various effects, such as being able to reduce.
