The present invention relates to a method for manufacturing a board containing silver particles, more specifically, aggregate wood, plywood, solid wood, MDF (Medium Density Fiber Board), HDF (High Density Fiber) without regard to the plate material By adding silver particles on the surface of boards and gypsum boards and printing patterns, it can prevent the symptoms of sick house syndrome caused by formaldehyde, etc. It is possible to provide shielding function, etc., and it is possible to mass-produce boards containing silver particles by automation system, so that silver particles which can improve work speed and reduce workmanship and improve productivity It relates to a method of manufacturing the contained board.

Recently, as interest in interior decoration is increasing, the use of high-quality wood with a natural atmosphere is increasing when manufacturing interior and exterior materials, mats, and furniture. However, the high-quality wood is not only expensive but also depends on imports in most cases, so it is not provided inexpensively to the general public.

Accordingly, the surface of a board, such as MDF or veneer veneer, is relatively inexpensive, and a decorative layer printed with various patterns such as wood or synthetic resin may be attached or printed directly.

However, the conventional board manufacturing methods as described above have a problem in that they are weak to moisture and heat and do not absorb or block harmful waves such as antibacterial, insect repellent, and electromagnetic waves, thereby contaminating indoor environment. Also, recently called Sick House Syndrome, it is a temporary symptom of eye and neck swelling or cough due to indoor fluid chemicals in a new house or building, and severely allergic diseases such as asthma, rhinitis and atopy. As a result, symptoms that are exacerbated by chemical hypersensitivity are becoming serious problems.

Formaldehyde is known as the most representative carcinogen causing such symptoms. The formaldehyde, as a toxic substance with an irritating odor, comes from building materials such as plywood, foaming agent, insulation, paint, and furniture. In particular, in buildings that use a lot of insulation, there are not many windows and many cases are sealed. In these buildings, indoor air is not well ventilated, which affects the human body. In addition, when the interior is newly built, a lot of formaldehyde is produced due to the building materials that enter the interior. In addition, formaldehyde irritates the human body, especially the neck, nose and eyes, causing symptoms such as allergies and colds, and may cause headaches, fatigue, and skin rashes. As such, formaldehyde has a great effect on the nervous system and organs as the hypersensitivity reaction occurs in the human body in a high concentration room.

In order to solve this problem, various techniques using fine silver particles produced by nanotechnology have recently been proposed.

In addition to the precious metal value, silver is widely used as a craft material and a money material, and it is found to be a natural antibiotic, having no side effects on the human body, and removing a number of harmful bacteria. Such silver is generally produced and used in the form of a colloidal silver solution, that is, a nanoparticle in a fine particle state using an electrolysis or chemical decomposition method.

As an example, Korean Utility Model 2001-31623 proposes a technique for adding silver particles to the top and bottom layers of laminated flooring, while Korean Utility Model 2001-31622 evenly mixes calcium sulfate, which is the main raw material of gypsum board. A technique for adding rock silver particles to a gypsum board has been proposed. In addition, in Korean Laid-Open Publication No. 2003-21963, silver ionized water is added to the upper and lower parts of wood, dense fiber board, synthetic wood, etc. A technique of laminating overlay paper and heating bonding is proposed.

Conventional techniques for adding silver particles as described above, in applying the silver particles to the board-shaped board, the size and weight, etc. of the characteristics of each board is different, so that they are applied to a variety of board materials and produced in large quantities There was a problem that was difficult to do. That is, the process for producing by adding silver particles to each board, etc. is not automated, there is a problem that the labor time is increased, the work time is long, productivity and economic efficiency is lowered.

The present invention has been made to solve the above problems, by applying silver particles to the surface of aggregate wood, plywood, wood, MDF, HDF, gypsum board, etc. The purpose of the present invention is to provide a shielding function such as environment-friendly, excellent antibacterial, deodorant and electromagnetic waves by preventing symptoms of sick house syndrome caused by formaldehyde.

In the method for manufacturing a board containing silver particles according to the present invention, as shown in Figure 1, (a) is seated on the top of the plurality of feed rollers 30 to rotate the board 20 to convey in one direction step; (b) applying silver particles (Ag +) on the board 20 conveyed by the conveying roller through a roller device; (c) applying an aqueous paint or an oil paint to which the silver particles are added to the board 20 through the roller device 40; (d) printing a pattern by a pattern formed on the roller device 40 on the board 20; (e) UV-coating the board 20 and irradiating ultraviolet rays to dry it; (f) smoothly polishing the surface of the board (20); (g) applying a flame retardant paint to the board (20); And, (h) it comprises a step of hot air processing on the board (20).

The board 20 is seated on top of the plurality of rotating rollers 30 to be transported in one direction (S10). In this state, the board 20 passes through the roller device 40.

2 and 3, the roller device 40 is connected to the drive motor 41 and the cushion member 42 provided on both sides, a pair of upper rollers 45a rotatably installed inwardly. ), A lower roller 45b installed at the center lower portion of the upper roller 45a and rotating in the transfer direction of the feed roller 30, and installed at both ends of the upper roller 45a and inclined at a predetermined angle. An outlet passage 46 is included.

In the roller device 40, silver particles in a colloidal state are introduced between the pair of upper rollers 45a rotating inward through an input pipe connected from one upper part, and a lower part of the roller device 40 is installed at a lower side thereof so as to transfer the board 20 in the transport direction. It is moved to the upper surface of the lower roller 45b to rotate. At this time, the board 20 to be transported by the transfer roller 30 passes between the lower surface of the upper roller 45a and the upper surface of the lower roller 45b, and silver particles are formed on the surface of the board 20. It is applied (S11). In addition, the outflow passage 46 serves to receive and discharge the silver particles flowing out of the upper and lower rollers 45a and 45b as a '-' shaped member having a substantially 'cross-section' in the roller apparatus 40. This prevents unnecessary debris from occurring.

Here, in addition to the silver particles introduced as described above, one or more materials selected from the group consisting of clay, ocher, blue clay, white clay and natural dyes to which silver particles are added may be further included. The material of the natural dye is classified as a plant, an animal, a mineral, etc., and can be used as a dye as it is or by some processing, and does not contain formaldehyde material. In particular, the minerals include soils such as various stones, loess, mud, charcoal, ash, and various minerals.

In addition, it may further include one or more materials selected from the group consisting of clay, loess, blue clay, white clay and natural dyes. Accordingly, the number of steps is added according to the number of coating materials fed by the roller device 40.

In addition, the cushion member 42 is installed on both sides of the roller device 40 to allow height adjustment of the upper and lower rollers 45a and 45b in consideration of the thickness of the board 20 to be transferred. That is, the cushion member 42 is installed so that the vertical gear connected to the handle part 43 intersects the horizontal gear in the gearbox. As the handle part 43 is turned, the horizontal gear engaged with the vertical gear is moved in the vertical direction to adjust the height of the upper and lower rollers 45a and 45b connected to the cushion member 42.

In addition, in the case of the gypsum board in the material of the board 20, the gypsum powder is formed of a flat plate material pressed against the gypsum powder, which is easily broken, but the upper and lower rollers 45a and 45b are formed by the cushion member 42. By adjusting the height, it can be applied to any board 20 regardless of the material at the time of passing through the roller device 40.

On the other hand, the board 20 to which silver particles are applied and transported through the upper and lower rollers 45a and 45b of the roller device 40 passes through the roller device 40 of the next step, and the silver particles are added thereto. An aqueous paint or oil paint is applied (S12). It is also possible to apply by adding silver particles to the oil paint generally used.

Subsequently, it is installed to a length of approximately 15 m and is transferred to a long hot air dryer (not shown) which dries the board 20 with hot air at 80 ° C. In addition to the long hot air dryer, during the steps (a) to (h), at least one hot air dryer for drying the board 20 is further included (D18).

The board 20 is transported after printing. UV coating is applied and irradiated with ultraviolet rays to dry (S14), the surface is polished smoothly (S15), the flame retardant paint is applied (S16).

Table 1 shows the results of applying and testing the flame retardant paint on the board 20 to which the silver particles were added.

(* The result was tested by the standard of flame retardant performance [KOFEIS 1001].)

As shown in Table 1, the test results of flame retardation time, residual time, carbon screening area and carbonization length are shown below the standard value of the flame retardant performance, and it can be seen that the flame retardant performance is excellent when silver particles are added.

Here, the non-combustible material is a material having a property that does not burn, and belongs to the flame retardant class 1 by the building method. That is, by adding silver particles to each board used as a non-combustible material and automated to enable mass production, there is a fundamental difference from the conventional method of separately applying a flame retardant paint after interior decoration.

On the other hand, the board 20 is coated with a flame retardant coating, the manufacturing process is completed while going through the hot air treatment (S17) and hot air drying.
