Description

A scar removal manufacturing process for motor car

The present invention relates to a method for producing an automobile scratch remover.

Conventionally, in order to remove automobile scratches such as nail marks and scratches, scratches were removed by using a transparent paint or a spray spray, which had the following problems.

Figure 1: Only minor scratches on the clear paint area.

It is a compound Wax-type product that is used to grind light scratches by polishing method, or to fill up the scratches to temporarily hide the defects by using a visual difference.

Fig. 2: Red-putty work and application method using cascade during some process of sheet metal painting work.

1) Only one or two coatings will expose the scratched area, and the stain will be applied to the surrounding surface, and the more severe the staining will be, the more repeated work is done to fill the scratched area.

2) After application, the paint flows down to form water droplets and wavy patterns.

3) The colors do not match.

4) The gloss of the coated part dies.

5) After the passage of time, the application area becomes cloudy.

The present invention was developed to solve the problem of removing the conventional automobile scratches,

In order to prepare an automobile scratch remover having a viscosity of cP41,000 by adding a certain amount of calcium carbonate (CaCO₃) to a mixture of paint and transparent paint.

Hereinafter, the manufacturing method of the present invention will be described in detail with reference to Examples.

(One). Manufacturing apparatus of the present invention

end. electronic scale

I. Dryer (50 ° to 100 ° with Timer)

All. Cylindrical Stirrer (Timer)

la. Left and Right Rotating Square Stirrer

hemp. Air heater (with 20 ° ~ 100 ° Timer)

bar. Hydraulic vessel

(2). Raw material of the present invention

end. Paint and transparent: Color paint for car paint, transparent Koryo paint, and swallow paint.

I. CaCO₃: Irrespective of conventional paints, it has value as a product in color absorption, color concealment, curability and shrinkage.

This product is manufactured by Wangpyo Chemical Co., Ltd. and its grade is ST5000.

Example

1. Classify raw materials (paint, CaCO₃, transparent paint) according to the mixing ratio by color.

The color can be classified into four types and according to the ratio shown in the following table.

Compounding ratio (% by weight)

Classification black White Pearl Red Paint 59% by weight 84% by weight 42% by weight 58 wt% CaCO₃ 35 wt% 8% by weight 16 wt% 35 wt% Transparent Paint 6% by weight 8% by weight 42% by weight 7 wt% Sum 100% 100% 100% 100%

2. Dry CaCO₃ in dryer at 50 ℃ for 30 minutes and remove water by drying to improve the binding of oil paint and transparent paint.

3. Mix the paint and CaCO₃ produced in the above process 2 with a cylindrical stirrer and stir. Stir for 40 minutes at 700 rpm in a cylindrical stirrer. In this process, the tangled CaCo₃ particles spread out finely to match the color of paint and maximize the absorption of color.

4. Mix and paint the transparent paint and the paint made in the above work process. Through this process, paint and transparency are mixed sufficiently to achieve a constant gloss in later construction.

5. Rotate the paint sufficiently stirred in the cylindrical stirrer to the square stirrer and increase the viscosity by the following method. After stirring at 20 ℃ air heater, change of rpm, working time and viscosity of square stirrer are as below table.

division rpm Time (min) Viscosity (cP) Task 1 600 30 3,000 Job 2 800 30 9,000 WORK 3 1000 30 15,000 WORK 4 1200 30 21,000 Task 5 1500 30 27,000 Task 6 1200 30 31,000 Task 7 1000 25 35,000 Activity 8 800 20 39,000 Task 9 600 15 41,000

As shown in the table, give a certain amount of time, increase the rpm1500 and then slowly lower the rpm600 to work. The work is done at viscosity cP41,000.

6. The product made in the above process 5 is stored in a vacuum container and injected into the tube is a product of the automobile scratch remover of the present invention.

The product of the present invention manufactured through the manufacturing process has the following characteristics.

◎ Convenience of work: Anytime, anywhere can solve the paint defect of car by simple and simple manual work by the method described in work manual.

◎ Practicality of work: Cost-It can handle about 7-8㎥ of scratches with 1Set and it is cheap because it can be reused. Time-Usually 30 minutes to an hour of work can solve the problem.

◎ Functionality of work: It is a multi-step process to handle scratches or defects on the painted surface and a technology-intensive composite product that condenses many work tools and contents necessary in the process into one product. It is toned and manufactured just like the original color, and it can be expected to achieve better results by harmonizing with the original color without damaging the existing background color when removing defects.

The difference between the scratch removal method and the conventional scratch removal method by the scratch removal agent prepared in the present invention as described above is as follows.

division The present invention Existing Method work method [Simple work using Hera] 1. Clean the scratches and the foreign matter around it with a cleaner product (acetone). 2. Squeeze out a small amount of invention (red bean size) about 3cm before the scratch. As the starting point of hera work in front of the 1-2cm of the invention, go along the scratched area to 3-4cm behind the scratched area. Using the Cleaner product, leave 2-3cm at the beginning and end of the scratch and wipe it perpendicular to the scratch. 5. After finishing work 4, wipe the container cleanly, and after about 5 minutes, repeat 2, 3, 4 work 2-3 times. [Polishing] 1. Grind the scratch and the surface around the scratch with a rough sandpaper. 2. Pade on the ground area 3. Grind and sand the padded area. 4. Apply gipadade to remove bubbles that appear after padade work. 5. Again grab the sandpaper. 6. Apply primer to the padded and ground areas. 7. It is sanded again by sanding. [Painting] 1. Work area and even normal areas are covered with paint five to six times throughout the board. The transparent paint is reapplied to the painted area. [Heat Treatment] Dry by heat treatment in the coating booth. Workability It only fills the scratches and does not damage the existing background color. The method of grinding and applying damages the existing colors, and repainting vehicles generally see the complete curing time of the paint in more than 9-10 months. Working diagram Simplify your work with documentation Professional technical man cost Treats about 7-8cm scratches with one set (reusable) The work method is expensive. time Approximately one hour (image 10 degrees Celsius indication) About 1-2 days Place No limit General facilities and work space for painting Environment No environmental pollution due to dust There is a possibility of environmental pollution by dust and various coating materials.

The present invention as described above is a groundbreaking automobile scratch removal agent that can remove the scratches, such as nail marks on the outer surface of the automobile by a simple manual operation.
