1 and 2 show a method of manufacturing a Hanji cover for illumination according to an embodiment of the present invention.

Referring to FIGS. 1 and 2, the method for manufacturing a Hanji cover for illumination of the present invention includes a step of preparing a paper, a step of attaching the paper to an acrylic plate, a pressing step and a step of coating the synthetic resin.

The above-mentioned paper making method is produced by mixing a duck fiber and pulp to prepare a mixture, and then grinding the mixture.

The dodecaflower fiber is a fiber (bast fiber) obtained by processing a bark-covered bark part of a tree branch such as a mulberry tree, a mulberry tree, a mulberry tree mulberry and a mountain mulberry tree, Lt; / RTI >

 The core fiber having a length of 3 to 100 mm can be used. By varying the size of the core fiber to 0.1 to 10 mm, 10 to 30 mm, 30 to 50 mm, and 50 to 100 mm, the Korean pattern can be widely varied. When the length of the core fiber is in the range of 3 to 40 mm, the operation is advantageous.

The pulp may be a known pulp. For example, natural pulp such as flax, hemp, cottonwood, wood pulp, laminates, hemp, wool, and the like can be used, and rayon, acrylic, and polypropylene, polyethylene and polyvinyl chloride, polystyrene, Amide and the like may be used.

The pulp is preferably used in the form of a short fiber having a length of 3 mm or less. When the length of the pulp is 3 mm or less, it is advantageous in terms of the dusty fiber and the adsorption surface.

In the present invention, the design of Korean paper can be diversified by adding natural materials. The natural material may be grass, clover, sycamore leaves, fallen leaves, doodose, or grasshoppers.

After mixing the above-mentioned dough fiber and pulp, natural materials and dapole are added to the dough fiber and the dough is sufficiently kneaded, followed by plowing a proper amount of Korean paper in a paper machine.

20 to 60 parts by weight of the pulp and 0.1 to 3 parts by weight of the natural material may be mixed with 100 parts by weight of the ground fiber. The daphniae may be used in an amount of 0.0001 part by weight or less.

Fig. 1 shows the attachment of paper to an acrylic plate using an adhesive, and Fig. 2 shows the attachment of a paper using acrylic pressure to an acrylic plate.

Referring to FIG. 1, the step of attaching the paper to the acrylic plate is performed by first applying an adhesive to both sides of the acrylic plate, and attaching the paper to both sides of the acrylic plate.

The acrylic plate may have a thickness of 30 to 600 탆, preferably 100 to 400 탆, so as to prevent deformation due to heat generation.

In the present invention, an adhesive is first applied to both sides of an acrylic plate. At this time, the adhesive can be applied with a coating roll of 50 to 200 mesh. Applying glue first to Hanji may result in the unwinding of Hanji.

Referring to FIG. 2, in the present invention, Korean paper can be attached to an acrylic pin by a pressure method without using an adhesive.

More specifically, after heating both sides of the acrylic plate with heat, the paper is attached to both sides of the acrylic plate. Followed by pressing with a roller as described later. That is, if the acrylic plate is heated to a heat plate at about 100 to 250 ° C for several seconds, the ductility of the acrylic plate is greatly increased. At this time, the paper can be attached to both sides of the acrylic plate and then pressed by a roller.

Alternatively, the paper may be placed on the bottom surface of the acrylic plate, followed by attaching the paper using a thermocompression press. The temperature of the thermocompression press may be in the range of 100 to 250 DEG C and the pressure may be in the range of 5 to 80 kgf / cm < 2 >.

In order to prevent warpage of the cover, the paper may be attached to both sides of the acrylic plate.

Further, in the present invention, the paper is pressed and attached using a compression roller at 5 to 80 kgf / cm 2, preferably 30 to 60 kgf / cm 2. The paper having a weight of 10 to 70 g / m < 2 > may be used, and the thickness of each paper layer may be 20 to 50 mu m, preferably 30 to 50 mu m. The total thickness of the one-side layer attached to both sides of the acrylic can be 50 탆 to 100 탆, preferably 50 to 70 탆, more preferably 50 to 60 탆. In the case of the thickness and the weight range, reduction of light intensity can be minimized while maintaining appropriate strength.

In addition, the thickness of the acrylic plate on which the paper is adhered may be 50 탆 to 650 탆, preferably 80 to 600 탆, and 150 to 500 탆.

The cover paper for illumination according to the present invention includes a paper sheet and a synthetic resin layer which are pressed and adhered to the upper and lower portions of the acrylic sheet with a predetermined pressure, thereby minimizing the deformation of the paper sheet due to heat while maximizing the transmission of light.

The synthetic resin coating may be a known polymer resin for a transparent film. As the synthetic resin, any one of polypropylene, polycarbonate, and polyethylene terephthalate (PET) may be used.

The method may be performed by mixing 1 to 5% by weight of a carbon material of at least one of graphite, carbon nanotube, carbon fiber, graphene and nano diamond with a transparent synthetic resin polymer.

The coating may be performed in the range of 0.01 mm to 1 mm and then dried at 75 to 100 degrees.

The carbon material may be dispersed in nano-size and mixed with the synthetic resin polymer.

The carbon material has excellent heat conduction characteristics and is excellent in heat radiation performance. The synthetic resin layer containing the carbon material can perform a heat radiation function as well as a waterproof function. The synthetic resin layer can prevent accumulation of heat in the paper cover and the illumination frame due to the LED irradiation for a long time.
