Method for polishing automobile painted surfaces using a polisher, polishing agent, and pad {METHOD FOR POLISHING CLEARCOAT LAYER OF AUTOMOBILE USING POLISHER, POLISHING AGENT AND PAD}

The present invention is a technology for polishing the painted surface of an automobile with a polisher. More specifically, it provides a standardized polishing process to provide excellent polishing results regardless of whether the operator is a beginner or an expert, and further reduces work time and improves polishing work efficiency. It relates to a method of polishing the painted surface of an automobile using a polisher, polishing agent, and pad.

Generally, due to physical or environmental factors, the paint surface of a car gradually ages and its glossiness decreases. Polishing the painted surface of an automobile is a process of removing scratches or swirl marks.

Referring to FIG. 1, the automobile paint structure includes a metal panel layer 140, a primer layer 130, a base coat layer 120, and a clear coat layer (paint surface) 110. There may be scratches on the clear coat layer (painted surface) 110 due to contaminants such as dust, tar, and pollen, acid rain, scratches, and household wear. Although not shown in Figure 1, contaminants may include resin dust, bird secretions, industrial fallout, etc.

If scratches occur on the painted surface of a car, or if the painted surface undergoes discoloration, discoloration, oxidation, aging, etc., the lifespan of the painted surface will inevitably be shortened and its external beauty cannot be maintained. Referring to FIG. 2(a), light incident on the mirror-smooth automobile painted surface 110 is reflected at an angle equal to the angle of incidence. Referring to FIG. 2(b), when regular reflection occurs on the painted surface 110 of an automobile, the image reflected from the painted surface and incident on the human eye is clear. On the other hand, referring to FIG. 3(a), if foreign matter exists on the automobile painted surface 110, the incident light is scattered in various directions. Referring to FIG. 3(b), when diffuse reflection occurs on the painted surface 110 of an automobile, the image reflected from the painted surface and incident on the human eye will have a blurry portion.

Currently, automobile paint surface gloss treatment is accomplished through a multi-step process using a dual polisher. However, in the case of car paint surface gloss treatment, there is a problem in that deep or large scratches or swirl marks cannot be completely removed due to methodological limitations. In addition, there is no established process for polishing automobile painted surfaces, and thus the efficiency of polishing work varies depending on the operator's skill level.

First, a method of polishing an automobile painted surface will be described with reference to FIG. 4. The method of polishing a car's painted surface consists of three processes.

In the first polishing step (S410), the painted surface of the car part to be worked is divided into first reference areas of a certain size, and then each first divided area is treated with a single polisher equipped with a first polishing agent and a single medium-bristle pad. This is the polishing stage.

In the second polishing step (S420), after completing the first polishing step, the painted surface of the car part to be worked is divided into second reference areas of a certain size, and each second divided area is treated with a second polishing agent. This is the step of polishing with a dual polisher equipped with dual medium-bristle pads.

In the third polishing step (S430), after completing the second polishing step, the painted surface of the car part to be worked is divided into third reference areas with a certain size, and each third divided area is treated with a third polishing agent. This is the step of polishing with a dual polisher equipped with dual sponge pads.

Referring to Figure 5, ① bonnet, ② front bumper, ③ front flap, ④ driver's seat front door, ⑤ driver's seat rear door, ⑥ rear flap, ⑦ trunk, ⑧ rear bumper, and ⑨ roof. The opposite of the driver's side front door and the driver's side rear door is the passenger side front door and the passenger side rear door.

The car paint surface polishing work according to the present invention is preferably performed on the bonnet, front fender, driver's side front door, driver's side rear door, trunk, rear fender, passenger side rear door, passenger side front door, front fender, roof, front bumper, and rear bumper in this order.

Figure 6 is an example diagram for explaining the polisher work direction according to the divided area. The standard area of Figure 6(a) is 30cm×30cm, and the standard area of Figure 6(b) is 60cm×60cm. The polisher's working direction is from left to right, that is, counterclockwise, which increases the friction between the pad mounted on the polisher and the car's painted surface.

The single medium-bristle pad and single sponge pad are 7 inches, and when used in a 30cm x 30cm divided area such as 6(a), the divided area must be divided into 2 parts and polished. Meanwhile, the dual medium wool pad and dual sponge pad are 5 inches, and when used in a 60cm x 60cm divided area such as 6(b), the divided area must be divided into 4 parts and polished.

Referring again to FIG. 4, the first polishing step (S410) is to divide the painted surface of the car part to be worked into N into first reference areas of a certain size, apply the first polishing agent to the divided areas, and apply a single polishing agent to the divided areas. Apply with a single polisher equipped with a pad and set to 1st gear.

The first polishing agent includes an abrasive, and the particle size of the abrasive is 1000 grit or more and 1500 grit or less. The first reference area is 30 cm x 30 cm, and the amount of the first brightening agent used in the first reference area (divided area) is 60 g or more and 120 g or less. If the amount of the first polishing agent is less than 60g, the polishing time becomes longer and the polishing efficiency decreases. If the amount of the first polishing agent is more than 120g, there is a problem that the glossiness of the car's painted surface decreases due to the repeated process of expansion and contraction during polishing.

In the first polishing step (S410), after applying the first polishing agent, the number of revolutions per minute (rpm) of the single polisher is set to 2, and the divided area where the first polishing agent is applied with a single medium-bristle pad mounted on the single polisher is divided. The first portion is polished for a first time (seconds) (1st-1 polishing step). Thereafter, with the revolutions per minute (rpm) of the single polisher set to 2, the second portion of the divided area to which the first polishing agent was applied is polished with a single medium-bristle pad mounted on the single polisher for a first time (seconds). (1st-2nd polishing step).

Here, the second stage of revolutions per minute (rpm) of the single polisher is 900 rpm, and the first time (seconds) is 12 seconds. Additionally, the 1-1 polishing step and the 1-2 polishing step can be repeated two times in succession. If you polish the same painted surface three times in a row, the gloss may decrease. However, it is possible to apply the first polishing agent again after a certain period of time and repeat the first polishing step and the first polishing step 1-2 twice in succession.

In the second polishing step (S420), after completing the first polishing step, the painted surface of the car part to be worked on is divided M into a second reference area of a certain size, and the divided area is coated with a second polishing agent, It is applied using a dual polisher equipped with dual medium-bristle pads and set to 6 speeds.

The second polishing agent includes an abrasive, and the particle size of the abrasive is 2000 grit or more and 3000 grit or less. The second reference area is 60 cm x 60 cm, and the amount of the second polishing agent used in the second reference area (divided area) is 60 g or more and 120 g or less. If the second polishing agent is less than 60g, the polishing time becomes longer and the polishing efficiency decreases. If the second polishing agent is more than 120g, there is a problem that the glossiness of the car's painted surface decreases due to the repeated process of expansion and contraction during polishing.

In the second polishing step (S420), after applying the second polishing agent, the revolutions per minute (rpm) of the dual polisher is set to 6, and the divided area where the second polishing agent is applied with the dual medium-bristle pad mounted on the dual polisher is divided. The first part is polished for a first time (seconds) (2-1 polishing step). Afterwards, with the revolutions per minute (rpm) of the dual polisher set to 6, the second portion of the divided area to which the second polishing agent was applied is polished for a first time (seconds) with the dual medium-bristle pad mounted on the dual polisher. (2-2 polishing step). Afterwards, with the rotation per minute (rpm) of the dual polisher set to 6, the third portion of the divided area to which the second polishing agent was applied is polished with the dual medium-bristle pad mounted on the dual polisher for a first time (seconds). (2nd-3rd polishing steps). Afterwards, with the rotation per minute (rpm) of the dual polisher set to 6, the fourth portion of the divided area to which the second polishing agent was applied is polished for a first time (seconds) with a dual medium-bristle pad mounted on the dual polisher. (2nd-4th polishing steps).
