At night driving is essential to turn on the headlights of the car to ensure the driver's visibility and safe driving. The glass cover has a small scratch on the surface after a long time, so the transmittance of the light is reduced, which is a rare phenomenon. However, the plastic cover and the acrylic resin light cover have a lot of minute scratches and ultraviolet rays on the surface due to contaminants such as heat, direct sunlight, wind, rain, dust, carbon, etc. of the light bulb over the last two years or more. Yellow or bluish discoloration is not only not good appearance, but also the light transmittance is reduced, the lighting efficiency gradually decreases. In addition, a car light that is discolored and has a low light transmittance may cause a driver's vision to be blurred when driving at night, causing a safety accident as well as a large accident.

Due to this problem, if the light is discolored because it is old or blurred, the transmittance of the light falls, and the driver's vision is blurred, it is necessary to replace it with a new light or repair it at a repair shop.

1. Replacing the lights is costly to motorists.

2. At the time of repair, in order to peel off the coating film of the automobile light cover, five to six kinds of polishing sandpapers (CW80, CW400, CW600, CW1000, CW1500, CW2000, etc.) are sequentially attached to the sanding machine, and the polishing sandpaper is used. The polished plastic surface is difficult to work by hand and it takes a lot of time, so it is necessary to work several times using a separate polisher.

3. More advanced light repair methods include a variety of sanding papers (# 1000, # 2000, # 3000, # 3500, # 4000, # 7000) with different types of sanding paper (4-12 microns, 15 microns, etc.). Since it must be polished and polished step by step, it is cumbersome to have various kinds of abrasives, sponges with different types of sanding papers, and microfiber towels. There was a problem that it is difficult to directly restore the car light cover.

An object of the present invention is to solve the above-mentioned problems of the prior art, by allowing the driver to quickly and simply restore the light plastic cover surface discolored due to fine scratches and staining of contaminants, ultraviolet rays and light bulbs heat, Not only can it reduce nighttime driving accidents caused by discoloration and poor light transmission, but it can also reduce costs and reduce oil resources efficiently.

1) 30 to 40% by weight of ion-exchanged water and 5 to 10% by weight of isoparaffin are agitated to prepare a plastic abrasive composition for a light cover that polishes the discolored and blurred automobile light plastic cover surface. After mixing for about 60 minutes, 5 to 10% by weight of hydrocarbon, 20 to 40% by weight of aluminum oxide, and 5 to 10% by weight of zirconium were sequentially added to the stirrer and mixed for about 30 minutes. After the total weight of 3 to 10% by weight of the organic solvent penetrant, 10 to 20% by weight of the surfactant, 2 to 3% by weight of the corrosion inhibitor are put in a stirrer, respectively, and mixed for about 60 minutes to stabilize.

The aluminum oxide added should be particles of 0.5 to 1 micrometer in size

Among the materials constituting the light abrasive, ion exchange water and isoparaffin remove impurities.

Hydrocarbons act as lubrication and solvents,

Aluminum oxide and zirconium serve to polish the light plastic surface and to remove the separated coating film of the light surface.

Organic solvent penetrant penetrates the coating surface of the light cover surface and separates it from the plastic surface.

The surfactant thins the coating film on the light cover surface to peel off the coating film from the light cover surface, and serves to control dispersibility and evaporation rate.

Preservatives serve to prevent corrosion of the light surface from which the coating film has been removed.

Conventionally, the use of abrasives for other purposes as subsidiary materials for plastic and acrylic-based abrasives increases the coefficient of friction on the surface of the light cover, resulting in surface scratches, difficult for the operator to work directly, and significantly longer grinding time. The light abrasive of the present invention allows the operator to directly, quickly, easily and simply polish the plastic and acrylic light cover surface.

2) 20 to 30% by weight of ion-exchanged water, 5 to 10% by weight of isoparaffin, based on the total weight of the composition, for the manufacture of a plastic-specific brightener composition for a light cover that gives a clear and transparent gloss to the plastic cover surface of a car light After mixing in a stirrer for about 60 minutes, 10 to 20% by weight of hydrocarbon, 30 to 40% by weight of aluminum oxide, 5 to 20% by weight of ferric oxide or chromium oxide were sequentially added to the stirrer, respectively. Allow 60 minutes to mix and stabilize.

However, the aluminum oxide to be added should be particles of 0.05 to 0.2 micrometers in size, and ferric oxide should also be particles of 0.05 to 0.2 micrometers in size.

Among the materials constituting the light polish, ion-exchanged water and isoparaffin remove impurities.

Hydrocarbons act as lubrication and solvents,

Ultrafine particles of aluminum oxide help to polish the plastic surface of the light more cleanly and finely.

Ferric oxide or chromium oxide serves to gloss the light plastic cover.

Conventionally, the gloss time was long due to the use of other-use varnish as a subsidiary of plastic and acrylic varnish, and the gloss did not appear clearly, but the present invention is a plastic and acryl-based varnish, so that the gloss work time is fast and perfectly polished. It was.

In the present invention, distilled water was used as ion-exchange water used in the plastic abrasive and the plastic polish.

Example of use

1) Apply 10 ml of the abrasive to the surface of light evenly and give it a little strength with a clean surface to wipe it for 1 ~ 3 minutes to remove discoloration and remove impurities on the surface of light yellow plastic cover or cracked coating. It turns clean and clear, and when 10 ml of abrasive is cleaned with an additional force on a clean side for an additional 1 to 3 minutes, it removes the cracked or cracked coating film on the plastic cover surface. At the end of the grinding process, very fine polishing marks, 0.2 to 1 micrometers in size, are hardly visible, leaving the plastic cover of the light slightly blurred.

2) After rubbing the surface of the plastic cover of the light with about 2 g of the light varnish on the clean side of the present invention, very fine polishing marks of 0.2 to 1 micrometers, which are difficult to see with eyes remaining on the surface of the light plastic cover, disappear and are tight. It is a clear and transparent luster with a conch.

3) In order to maintain the gloss of the light plastic cover for a long time, a coating is applied by applying a commercially available automotive coating or wax coating agent.

Example
