A method for manufacturing a furniture panel having flame-retardant and antibacterial functions according to an embodiment of the present invention includes the steps of preheating a core material 210 with a UV lamp, performing primary flame-retardant treatment on the surface of the preheated core material 210 and drying; Repeating the steps of painting and drying the water-based paint, coating the combination of the water-based paint and the antibacterial material to give the first antibacterial treatment and drying, coating the combination of the UV coating agent, the flame retardant, and the antibacterial material may include

First, before preheating the surface of the core material 210 , the surface of the prepared core material 210 of the furniture panel may be polished ( S110 ). In this case, the surface of the core material 210 may be polished by a sanding operation, and the smoothness of the surface of the core material 210 may be improved by polishing.

As the core material 210 of the furniture panel, a particle board (PB), a medium density fiberboard (MDF), a high density fiberboard (HDF), etc. may be used, but the present invention is not limited thereto.

Particle board is a processed material made by crushing the waste residues left after producing wood from solid wood into small pieces, then mixing the adhesive with high temperature and high pressure and pressing it. It can be done in a variety of ways, and it is efficient and economical in terms of recycling waste residues generated during the processing of various logs.

MDF is a plate material obtained by compressing wood fibers obtained from wood materials together with an adhesive at high temperature and high pressure. It has a dense and uniform structure and excellent machinability and strength, so it replaces general wood for furniture and speaker appearance It is widely used as a material for , ping-pong tables, etc. In addition, since the surface is hard and smooth, it is easy to use by applying paint or adhering a decorative film.

HDF is manufactured with a much higher compression ratio than MDF. It is made with high density, so it is hard and heavy and uses a lot of wood, but it has the characteristics of reducing the amount of adhesive used.

Next, the surface of the core material 210 is preheated using a UV lamp (S120). In particular, in the winter season, the surface temperature of the core material loaded in the warehouse or the like may be lowered, and the surface temperature of the core material is maintained constant through the preheating process.

Next, a primary flame-retardant treatment is performed on the surface of the preheated core material 210 to form a flame-retardant layer 220 and dried (S130).

A flame-retardant treatment may be performed by applying a flame-retardant material to the surface of the core material 210 in a roll coating method. In addition, the drying process is preferably performed at a high temperature of 170 by irradiating ultraviolet rays with a wavelength of 320 nm using a mercury lamp or a color lamp. The temperature may vary in a predetermined range depending on the ambient temperature at which the process is performed. As will be described later, in the present invention, total volatile organic compounds (TVOC) and form harmful to the human body by performing sterilization and drying inside the heart material 210 with high-temperature heat by the ultraviolet wavelength emitted from the UV ultraviolet lamp in each step. The occurrence of aldehydes can be minimized.

At this time, drying is performed using a UV UV lamp in this step as well, and it is preferable to irradiate the UV light with a wavelength of 320 nm to perform the drying at a high temperature of 170 °C.

Next, the water-based paint is secondarily coated and dried (S150). Similarly, the water-based paint is applied by a roll coating method, and this step is a surface coating operation. Similarly, in this step, drying is performed using a UV UV lamp, and it is preferable to irradiate UV rays with a wavelength of 320 nm to perform at a high temperature of 170 °C.

Next, the water-based paint is painted and dried (S160). Similarly, the water-based paint is applied by a roll coating method, and this step is also a surface intermediate coating operation. Similarly, in this step, drying is performed using a UV UV lamp, and it is preferable to irradiate UV rays with a wavelength of 320 nm to perform at a high temperature of 170 °C. The water-based paint layer 230 may be formed by the steps S140 to S160.

Next, the antibacterial layer 240 is formed by coating and drying the mixture in which the antibacterial material is mixed with the water-based paint in the fourth step (S170). Also in this step, the formulation is applied by a roll coating method, and this step is a surface color top coating operation. Similarly, in this step, drying is performed using a UV UV lamp, and it is preferable to irradiate UV rays with a wavelength of 320 nm to perform at a high temperature of 170 °C.

A mixture of 3-iodopropargyl-N-butylcarbamate and dipropylene glycol can be used as the antibacterial substance used. In this case, the content of 3-iodopropargyl-N-butylcarbamate is preferably 29 to 31%. Alternatively, nano-silver colloids can be used as an antibacterial material, and the nano-silver colloids are a mixture of silver colloidal (0.5%), phosphoric acid (1-2.5%), sodium sulfite (3%), and water (93.5-95%). can be composed of

It is preferable to use an eco-friendly water-based paint as the water-based paint used in each of the above steps.

Although not shown, after the antibacterial layer 240 is formed, a pattern may be formed on the surface through a printing operation.

Finally, the UV coating agent is coated with a combination of a flame retardant material and an antibacterial material, and dried to form a functional coating layer 250 (S180). That is, after the primary flame-retardant treatment by the flame-retardant layer 220 and the primary antibacterial treatment by the antibacterial layer 240 by the coating of the functional coating layer 250, the flame-retardant treatment and the antibacterial treatment may be additionally processed.

It is possible to further improve the flame retardant or antibacterial function by the coating process, and it is possible to minimize damage to the surface by scratching.

The furniture panel manufactured according to the present invention described above does not use an adhesive, but uses high-temperature thermal energy irradiated from a UV UV lamp to sterilize and dry the inside of the heart material 210, thereby sterilizing the total volatile organic compounds (TVOC) harmful to the human body. ) or an eco-friendly product that minimizes the generation of formaldehyde. In addition, it is a functional furniture panel that can use various printed patterns on the surface, and has both flame-retardant and antibacterial functions.
