Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

It should be understood, however, that the scope of the present invention is not limited to these embodiments, and all of the technical ideas that fall within the scope of the present invention are within the scope of the present invention.

The present invention is summarized as follows.

A method of painting a surface using a lacquer, comprising the steps of preparing a lacquer (S-100) for preparing a color lacquer (20) and a lacquer (10) and an object to be painted; And a surface polishing step (S-200) for polishing the portion to be coated of the prepared object to be coated.

The reason for polishing is that the lacquer is more easily adhered to the object.

After the surface polishing step (S-200), the color lacquer adjusting step (S-210) for adjusting the concentration of the color lacquer is performed by diluting the terrapin oil 30 with the color lacquer.

After the color lacquer concentration control step (S-210), a primary lacquering step (S-300) is carried out on the polished surface of the object to be painted with a color lacquer (20) For 15 minutes to 40 minutes to cure the first lacquer (S-400). Although not necessarily limited to the above temperatures, the degree of curing at such temperatures is highly desirable.

After the primary curing step, a second lacquering step (S-500) is carried out to coat the first lacquer with lacquer to coat the pattern in the first lacquer step. Coating can prevent contact with air, and can prevent the pattern from being damaged by other moisture and contaminants.

The second curing step (S-600) is further preferably carried out after the second lacquering step at 100 to 200 ° C for 5 minutes to 25 minutes to cure the lacquer. The cloth of S-500 can be further cured.

That is, the present invention is characterized in that a step of engraving a pattern using a color lacquer, including a polishing and curing step, and a step of coating the engraved pattern using lacquer are added to a coating material which is difficult to be lacquered such as acrylic or glass I would like to suggest how to do this.

FIG. 2 is a view illustrating a step of preparing a lacquer in a surface painting method using natural lacquer according to an embodiment of the present invention S-100). FIG. 3 is a photograph of the surface polishing step (S-200) of the surface painting method using the natural lacquer according to the embodiment of the present invention.

FIG. 4 is a photograph of a color lacquer adjusting step (S-210) of a surface painting method using natural lacquer according to an embodiment of the present invention. This is the first lacquering step (S-300).

Glass, or other synthetic resin material, is not necessarily limited to wood.

FIG. 6 is a view illustrating a first curing step (S-400) of a surface painting method using a natural lacquer according to an embodiment of the present invention. However, it is preferable to cure the surface with a heater hot wire. However, The case of the branch drying method shall not be excluded.

FIG. 7 is a view showing a state in which a drawn pattern is prevented from coming into contact with air by performing a second lacquering step (S-500) of a surface painting method using a natural lacquer according to an embodiment of the present invention, .

FIG. 8 is a view illustrating a second curing step (S-600) carried out in a curing machine for additional curing after step S-500. FIG. 9 is a view illustrating a method of applying a surface coating method using natural lacquer according to an embodiment of the present invention, This is the first picture to complete.

In Fig. 10, there is shown another product with another pattern drawn.

On the other hand, a method of manufacturing a thin plate for absorbing electromagnetic waves is proposed by applying the lacquer coating method of the present invention.

FIG. 11 is a flow chart showing the overall progress of the method of manufacturing such an electromagnetic wave absorbing card, and FIG. 12 is a photograph showing a completed electromagnetic wave absorbing card manufacturing method according to the embodiment of the present invention.

These lacquered laminate products can be used in a number of products for electromagnetic shielding, such as mobile phone cases, computer monitor peripherals, or heating mat peripherals.

The manufacturing process of the thin plate is as follows.

That is, after a thin plate preparing step S10 for preparing a thin thin plate, a laser processing step S20 is performed in which the prepared thin plate surface is laser-engraved in the vertical direction so as to match the result of the wood formed on the thin plate.

In this case, particularly in the case where the thin plate is made of wood in the step S20, if the text is formed in the up and down direction and the laser is processed while the letters are laid out, Laser processing should be performed in the direction of

Then, after the laser processing step, the laminate is prepared to be more easily adhered to the thin plate surface by performing the thin plate surface polishing step (S30) for polishing the surface of the thin plate.

Then, a thin lacquer step (S40) for lacquering the polished thin plate surface is performed, and a curing process is performed.

At this time, the wood or acrylic material is not cured in the place where the heater is installed, but the lacquer is cured in the place of humidity (wet drying). That is, after laminating the lacquer (S40), in order to cure the lacquer under the wet condition, A wet curing step (S50) is carried out in which the temperature is 20 to 50 DEG C and the humidity is 60 to 95% and the drying is performed for 20 to 30 hours in a wet room.

The chamber for performing the wet drying is such that the water contained in the cedar is gradually evaporated by providing a wood which is capable of finishing well, such as cedar, on the inner wall of the chamber so that the wet curing of the lacquer portion is performed.

Preferably, the bottom of the wet drying chamber further includes a heating unit for heating water to supply water vapor.
