Description

Antibacterial steel gypsum panel structure {ANTIMICROBIAL STEEL GYPSUM PANEL STRUCTURE}

The present invention relates to panel structures, and more particularly to antimicrobial steel gypsum panel (SGP) structures.

In general, clean rooms are used to improve product quality and lower defect rates in manufacturing process lines that require a high clean environment, such as semiconductor manufacturing processes, pharmaceutical manufacturing processes, and various food manufacturing processes. In addition, clean rooms are also used in hospital intensive care units and operating rooms. This clean room has a structure that is thoroughly blocked from the external environment in order to block the inflow of dust or germs. In addition, efforts are being made to provide an environment in which dust or germs are hardly generated in the clean room.

On the other hand, in a clean room, there are many cases where a partition construction is performed to divide the work space. In order to divide the space with partition construction, panel construction is being carried out a lot. Korean Patent Registration No. 10-1150024 discloses a panel for a clean room including an operating room equipped with an antibacterial function.

However, conventional panel structures for clean rooms mainly provide an antibacterial function only to the panel itself, that is, to the steel plate. Since the conventional panel structure has an antibacterial function only on the panel, there is a risk that fine dust adheres to the connection part connecting the panels or other parts of the finishing material and bacteria propagates. Therefore, as a conventional panel structure, there is a danger in using it in a semiconductor manufacturing plant requiring a fine manufacturing process or in an operating room directly related to a patient's life.

The present invention is to solve the above-described technical problem, an object of the present invention is to provide an antibacterial steel gypsum panel (SGP) structure in which the entire surface of the panel structure is treated with antibacterial treatment.

An antibacterial steel gypsum panel structure according to an embodiment of the present invention includes a plurality of panels surface-treated with an inorganic antimicrobial agent; and connection units that connect the plurality of panels and are surface-treated with the inorganic antibacterial agent. Each of the plurality of panels includes two steel plates spaced apart from each other and facing each other; two gypsum boards disposed between the two steel plates and spaced apart from each other and facing each other; and studs disposed between the gypsum boards. Each of the plurality of panels includes a base metal plate, a first zinc layer sequentially laminated on the upper surface of the base metal plate, a first pretreatment layer, an undercoat layer, and an upper coat layer sequentially laminated on the lower surface of the base metal plate. It may include 2 zinc layers, a second pretreatment layer, and a functional paint layer.

In the antibacterial steel gypsum panel structure according to an embodiment of the present invention, an inorganic antibacterial agent is applied to each of the parts exposed to the outside (eg, the top coat layer of the panels, the cover part of the connection unit, the base plate, the ceiling plate, and the finish plate). can include Since the panel structure of the present invention has a complete antibacterial function, it can be safely used in places where damage due to fine dust or bacteria is concerned, such as semiconductor manufacturing factories, various laboratories, sterile rooms of pharmaceutical companies, and operating rooms of hospitals.

Hereinafter, embodiments of the present invention will be described clearly and in detail to the extent that those skilled in the art can easily practice the present invention.

1 is a vertical cross-sectional view for explaining an antibacterial steel gypsum panel structure according to an embodiment of the present invention, and FIG. 2 is a horizontal cross-sectional view for explaining an antibacterial steel gypsum panel structure according to an embodiment of the present invention.

1 and 2, the antibacterial steel gypsum panel structure 10 includes a plurality of panels 100, connecting units 200 for each panel 100, and a rag disposed under the panels 100. It may include a receiving 300, a ceiling receiving 400 disposed above the panels 100, and a finishing receiving 500 closing both ends.

Each of the panels 100 may include two steel plates 110 spaced apart from each other and facing each other, two gypsum boards 120 spaced apart from each other and facing each other, a stud 130, and a filler 140. The two steel plates 110 may face each other with a first length LT1 and be spaced apart from each other. In this case, the direction in which the two steel plates 110 are spaced apart may be the thickness direction of the panel 100 . Each steel plate 110 may be composed of a plurality of layers.

3 is a view for explaining a steel plate of an antibacterial steel gypsum panel structure according to an embodiment of the present invention. Referring to FIG. 3 , according to an embodiment, a steel sheet 110 includes a base metal sheet 101, a first zinc layer 102 sequentially disposed on an upper surface of the base metal sheet 101, and a first pretreatment layer 103. ), the lower coating layer 104 and the upper coating layer 105, the second zinc layer 106 sequentially disposed on the lower surface of the base metal plate 101, the second pretreatment layer 107, and the functional paint layer 108 can include The surface of the steel plate 110 exposed to the outside may be the top coat layer 105 . That is, the top coat layer 105 is exposed to the outside, and the functional paint layer 108 may face the gypsum board 120 .

The base metal sheet 101 may include a cold rolled steel sheet. For example, the base metal sheet 101 may be galvanized (GI), alloyed galvanized steel (galvanneled, GA), aluminum-galvanized steel (galvalume, SGL), or electro galvanized (EGI). , Aluminum steel plate (aluminum, AL), cold rolled stainless steel (stainless steel, SUS), black plate (BP), TFS, TP, may include at least one of ALCOT (hot dip aluminized steel).

Each of the first pre-treatment layer 103 and the second pre-treatment layer 107 may be a layer coated with chromate. The functional paint layer 108 may include at least one of epoxy and polyester.

The top coat layer 105 is a layer through which the steel plate 110 is exposed to the outside, and the top coat layer 105 may contain an alkaline earth metal crystalline alminosilicate and an inorganic antibacterial agent. Inorganic antibacterial agents replace metal ions having antibacterial properties such as silver (Ag), copper (Cu), manganese (Mn), and zinc (Zn) in inorganic carriers such as zeolite, silica, and alumina. Because it has a three-dimensional skeletal structure with fine pores, it has a large specific surface area and excellent heat resistance. For example, the inorganic antibacterial agent of the top coat layer 105 may include zeolite in which silver is ion-bonded (Ag-zeolite).

On the other hand, the corrosion resistance and chemical resistance of the steel plate 110 can be improved by special coating the inner and outer surfaces. In addition, the steel plate 110 includes a special non-static paint, and the surface electrical resistance of the panel structure 10 can be maintained at 10 ⁶ to 10 ⁹ Ω by the special non-static paint, so that it can have semi-permanent antistatic performance. When static electricity is generated, dust contamination and ESD discharge can cause electronic components to rupture or deteriorate.

When charged dust floating in the air approaches a charged object, the dust may stick to the surface of the charged steel plate 110 due to the attraction of Coulomb force generated by electrostatic induction. In order to prevent this, the surface of the steel plate 110 may be coated with an electrostatic paint to prevent dust from adhering to it. In addition, when the surface of the charged steel sheet 110 is discharged to an electronic component or an object to be coated, the discharge current passes through a region of low resistance of the electronic component or object to be coated. The thermal energy generated at this time may cause thermal damage in proportion to the discharge current. Therefore, ESD discharge can be prevented by coating the surface of the steel plate 110 with an electrostatic paint.
