The present invention relates to a conductive printed pattern paper, and a conductive melamine decorative plate including the same. In particular, the present invention relates to a conductive printed paper, which is environmentally friendly, has excellent conductive properties and antistatic performance, and is implemented so that the shape of a printed pattern can be visually observed, and a conductive melamine decorative plate including the same.

As office automation and computerization become popular, flooring materials with challenging functions are used in computer control rooms, office spaces, air control rooms, banks, and other PC-equipped spaces. This plays an important role in protecting the program from static electricity.

Currently, various types of flooring materials are used, but the most commonly used conductive flooring materials are PVC floorings using thermoplastic resins. This is a flooring material which is laminated by mixing conductive carbon black with PVC. Usually, products with a thickness of about 2 to 4 mm are used a lot. This has a number of advantages in terms of processability and productivity, but in terms of environment-friendly, it has a problem that is not environmentally friendly by releasing dioxin and harmful substances harmful to the human body when incinerated. In addition, the thickness of the product can not be produced thin, there is a problem that the thickness variation of the flooring occurs badly and the surface is easily contaminated or deformed during use. In addition, the pressing strength of the product may be weak, causing inconvenience to the need to adjust the horizontal balance from time to time when using precision measuring instruments and heavy laboratory equipment.

Another type of product is partially produced as a melamine decorative plate using a thermosetting resin, but this also has various problems.

Melamine vanity uses colorless transparent melamine resin. In general, melamine decorative plate and the shape paper impregnated and dried the melamine resin; It is a thin laminate plate heat-cured by combining kraft paper impregnated and dried with a phenol resin.

Korean Patent Laid-Open Publication No. 2002-7750 discloses a conductive melamine decorative plate obtained by impregnating and drying a conductive material and an additive in a melamine resin in a manufacturing process. However, since the additives are mostly composed of powder, conductive materials are precipitated when mixed with the resin, which causes a problem of uneven quality at each operation.

In addition, since the conductive materials contain pigments, there is a problem that it is difficult to recognize the texture of the pattern by blurring the sharpness of the pattern paper layer. Furthermore, in order to impart conductivity, the coating layer of the conductive additive must be uniformly formed in the entire area of the printing layer, so that a large amount of the added amount can be expected to expect the desired physical properties. This leads to an increase in manufacturing costs.

In addition, since the flooring material basically requires abrasion resistance, it is common to laminate the transparent paper on the upper layer of paper and heat-cure it. As described above, the conductive material itself is an opaque material, so that the shape of the pattern layer is covered. There is a problem.

On the other hand, double flooring is used for various purposes such as computer room flooring and general offices. This is to facilitate installation or dismantling when using a computer, for a number of wires.

The double flooring may be composed of a surface material and a backing material, which relates to a backing material conductive material, it is common to use a material having an antistatic function, and to have a conductive function.

Currently, as a backing material, a thin aluminum plate of 0.15 to 0.25 mm and a carbonized phenolic plate may be bonded to each other. This aims to protect the computer's programs and the health of the people who use them from static electricity. In addition, it is another object to prevent the generation of static electricity where the friction is generated, such as a belt guide plate used in the treadmill machine used in the gym.

In these places, carbonized phenolic plates, low pressure melamine plates, or conductive oils may be used. This is to prevent the strong static electricity generated when the synthetic nylon fiber belt is rotated.

Currently, as a representative surface material of the double floor material being used, various types of materials, such as PVC conductive flooring material or conductive carpet, conductive melamine decorative board, are used. However, as the conductive material used for the rear surface of the double floor covering, a sheet plate obtained by thermosetting an aluminum thin film or a conductive carbon treated phenol resin impregnated substrate is used.

However, the aluminum thin film is expensive and weak to moisture due to corrosion caused by moisture generated on the floor during long-term use. In addition, in the case of a sheet plate heat-cured kraft paper impregnated with a phenolic resin containing conductive carbon, the work process is difficult and expensive, and the double layered material is contaminated with carbon on the surface of the product during processing and transportation, which makes it difficult to clean after installation. Is generated.

Therefore, the present invention is environmentally friendly because there is no concern about the generation of harmful substances due to PVC tiles, and the conductive printed pattern implemented to solve the opacity and non-uniformity of the conductive function of the conventional conductive melamine decorative plate, and the unevenness of the coating amount due to precipitation of the conductive material. Paper and a conductive melamine decorative plate including the same.

Implementation of the net or mesh form may use a printing cylinder made by carving the surface into a net or mesh form, which may be by a method of pressing the paper enumerated above, but is not limited thereto.

Conventionally, in order to implement conductivity in a melamine decorative plate, a conductive powder was mixed and used in a batch of melamine resin. In this case, it is difficult to expect uniform conduction performance because the conductive materials settle in the resin and sink over time. In addition, there is a problem in that the shape of the pattern layer is covered by the conductive material in the conventional working method of mixing and impregnating the conductive powder into the resin.

In order to solve such a conventional problem, the conductive printed paper according to the present invention connects the conductive material in the form of a continuous line in the form of a net or a mesh, so that even a small amount of conductive material can realize uniform conduction performance over the entire area. have.

Is 5 to 10% by weight relative to the phenolic resin, and the unit basis weight of the kraft paper impregnated with the phenolic resin containing the conductive carbon black is preferably 160 to 250 g / m 2. This is because suitable strength and smoothness can be maintained when laminating with pattern paper.

Optionally, a transparent surface protective paper (transparent paper) may be further laminated on the top of the printed pattern paper to increase the wear resistance of the decorative plate and to protect the printed pattern layer. In this case, the transparent paper is a conductive material printed on the transparent paper by using a printing cylinder manufactured by engraving in the form of a net or mesh as described above, preferably impregnated with melamine resin. In this case, the unit basis weight of the transparent paper is preferably 20 to 40 g / m 2, since various shapes of the printed pattern paper can be observed in the above-described range, so that smoothness and wear resistance can be obtained.

The conductive melamine decorative plate as described above, the step of laminating the conductive printed pattern paper impregnated with the melamine resin or phenol resin on the conductive printed pattern paper, and kraft paper impregnated with the phenol resin containing the conductive carbon black; And it may be formed by a manufacturing process configured to include the step of thermosetting the laminate.
