The present invention relates to a corrosion-resistant impervious plate material for the storage of cultural properties used as the exterior wall finishing material of the storage for preserving cultural properties in museums, etc., and in particular to the patents of the applicants of the present invention Patent Nos. 341631, 434576, and 471717 Corrosion resistance was strengthened using the aluminum sheet layer containing an anti-corrosive paint in the impermeable board | substrate for cultural property storage of the arc.

In general, cultural property is preserved in museums or other specific places, and in order to safely preserve the cultural property, it is necessary to keep the temperature and humidity required by the cultural property uniformly, while preventing the risk factors from invading from the outside.

In the prior art, wood such as paulownia, cedar, or spruce (SPRUCE: North American spruce), which have moisture-absorbing properties, are processed and used as an inner wall finishing material of the cultural storage, so the inner wall of the storage is used as the wood. When built, its own characteristics cannot control the humidity required by the cultural assets stored in the storage, so recently, the internal temperature and humidity of the storage are controlled using a constant temperature and humidity cabinet.

However, the thermo-hygrostat has the advantage of controlling the temperature and humidity of the indoor air while circulating the air inside and outside by mechanical operation, while the constant temperature and humidity must be continuously operated to keep the indoor temperature and humidity constant at all times. It is pointed out that the operation cost of the humidifier is high, and because the thermo-hygrostat is a machine, it is not possible to control the temperature and humidity at the time of failure or power failure, and the sudden change in temperature has a significant effect on the damage of cultural property. In spite of the madness, the temperature and humidity control by mechanical air conditioning may be an intermittent operation as a means to reduce the maintenance cost.A drastic temperature and humidity change occurs in the cabinet due to the intermittent operation of the thermo-hygrostat. If there was a problem that damaged the cultural property .

When using solid wood such as paulownia or cedar as an impervious material, it can be damaged by external pollutants and can not maintain the airtightness inside the cabinet, especially when it is damaged by moisture, germs, and insects. There was a problem that the cultural properties (relics) stored in the storage can not be safely protected because the phenomenon that the stored cultural properties (relics) is damaged by affecting the temperature and humidity inside the storage.

That is, when the inner wall surface of the storage cabinet is constructed from the above-mentioned wood, the risk factors such as alkaline factors or harmful gases emitted from the concrete wall surface are not blocked, but rather, the dangerous factors are absorbed and released into the storage cabinet. There was a problem that important cultural property or artifacts were damaged from the above mentioned risk factors.

In addition, the wooden wall of the cultural asset storage room has a disadvantage of insufficient heat insulation and also does not block the fire in the event of a fire.

On the other hand, in order to solve this problem, an impermeable plate material of a method of compressing and molding particles such as sawdust to form a three-layer particle board and finishing the particle board with an aluminum sheet has been proposed by the present applicant. Even when constructing the inner wall surface of the storage, there is a problem that corrosion occurs on the aluminum sheet due to moisture and the like, which damages important cultural assets or relics, as well as the fire resistance and barrier properties of the inner wall of the cultural storage due to corrosion.

The present invention is to solve the above problems, by crushing the waste wood materials such as by-products such as by-products generated from the wood material and the cutting wood remaining after the furniture is produced to form particles and compression molding them to produce a particle board By forming the inner wall of the cultural heritage storage by using it to provide a corrosion resistant impervious plate material and a method of manufacturing the same, which can significantly reduce the production cost while blocking the temperature and moisture to the same level compared to the case of using wood The purpose.

According to an embodiment of the present invention by forming an aluminum sheet on both sides of the particle board to improve the fire resistance in the event of a fire to prevent the loss of important cultural properties due to fire corrosion resistant impermeable plate material for the storage of cultural properties and its manufacturing method To provide for other purposes.

You may.

Figure 3 shows a method of manufacturing a corrosion-resistant impervious plate 1 according to an embodiment of the present invention. Method for producing a corrosion-resistant impervious plate 1 is a wood shredding step (S10), a drying step, a particle sorting step (S20), a resin coating step (S30), a particle lamination step (S40) for producing a particle board (2) , Corrosion-resistant material coating process (S80) and particle board (2) and the inside of the press forming process (S50), cooling process (S60) and cutting and polishing process (S70) and the corrosion-resistant aluminum sheet (3a, 3b) Aluminum sheet joining process (S90) which joins corrosive aluminum sheets 3a and 3b is comprised.

Hereinafter, the manufacturing method of the corrosion-resistant impervious plate member 1 according to an embodiment of the present invention for each process.

<Shred Process>

First, using a shredder to perform a shredding step (S10) of shredding the wood into particles of small particles, such as the size of sawdust. Shredding process (S10) is to crush the wood by the crusher by using the wood products, such as by-products generated when sawing the wood or cut wood and waste wood generated during furniture manufacturing, and the size of the particles, ie particles of the wood chips to be crushed Shred the same size as sawdust.

This shredding process is a second shredding process of shredding the pieces of wood shredded in the first shredding process with a shredder when it is difficult to shred the raw material wood to the size of sawdust by the first shredding process. In this case, the particles are broken into large or small sizes based on sawdust.

<Drying process>

Next, a drying process of drying the crushed particles by high temperature treatment is performed. The drying step is to dry the particles produced in the crushing process with a high temperature hot air of 350 ~ 450 ℃ (preferably 400 ℃), at this time to maintain the moisture content of the particles to be dried about 2-7%.

<Particle sorting process>

Next, a particle sorting process (S20) of sorting the dried particles into large particles and small particles is performed. The particle sorting step (S20) is to sort the particles dried in the drying step to distinguish between the large particles shredded to the size of the sawdust or slightly larger than the small particles smaller than the particles of the sawdust, the sorting operation at this time It is preferable to use a meshed screen.

More preferably, in the particle sorting process (S20), foreign substances such as metal fragments, small stones, and dust mixed in large particles and small particles may be selectively removed.

<Resin coating process>

Next, a resin coating process (S30) is performed in which a resin adhesive is sprayed onto the selected large particles and small particles and applied to the surface of each particle.

Preferably, the foreign matter is removed, and the resin adhesive in the liquid phase and the antimicrobial material may be mixed and applied to the surface of the particles separated into large particles and small particles. At this time, the application of the resin adhesive and the antimicrobial material is to separate the large particles and small particles selected by size separately and transport them to the conveyor belt, spraying a mixture of the resin adhesive and the antimicrobial material with a spray to spray the large particles and the small particles. The resin adhesive and the antimicrobial material are mixed evenly on the surface of each particle.

In addition, resin adhesives use natural resins that have less properties of wood and less formaldehyde emissions.Antibacterial materials use iodine-based and chlorine-based composites with strong antifungal functions. The antimicrobial material is mixed in an amount in the range of 600 to 800 ppm with respect to the amount of the resin adhesive used to bind the particle particles. The reason for limiting the mixing amount of the antimicrobial material to 600 to 800 ppm with respect to the amount of the resin adhesive is that the antimicrobial action may be insufficient when the antimicrobial material is at least 600 ppm, and the antimicrobial action may be less than the maximum value of 800 ppm. When the expensive antibacterial materials are used unnecessarily, the same is not only a factor of cost increase but also a possibility of inhibiting the bonding strength of the resin adhesive.

<Particle lamination process>

Next, a particle lamination step (S40) is performed in which a large particle coated with resin is placed in a deep layer, and small particles are positioned in a surface layer and a back layer of a deep layer to form a particle mat laminated in a triple structure.

First, small particles are distributed in a predetermined thickness to form a small particle layer 2b, and then large particles are laminated and distributed in a predetermined thickness on the small particle layer 2b to form a large particle layer 2a. In order to form a small particle layer 2c by stacking and distributing small particles again in a predetermined thickness on 2a), a large particle layer 2a is distributed in the deep portion, and small particle layers 2b and 2c are disposed in the surface layer and the back layer. The particles are distributed to form an uncompressed particle mat in which each particle layer is triple stacked.

In such a process, each particle in an uncompressed state in which a resin adhesive and an antimicrobial material are applied together is laminated in a triple layer, and each particle layer in a triple layer is sequentially stacked.

<Press molding process>

Particle layer laminated in the particle stacking step (S40) by the press molding step (S50) by pressing a high-temperature and high-pressure press on the particle mat by pressing each particle layer to a predetermined thickness and tightly adhered to complete the molding of the particle board .

In the press molding step (S50), the press for thermopressing each of the three-layered particle layers is distributed in each particulate layer with a high temperature of about 180 to 250 ° C. capable of thermally curing the resin adhesive applied to the surface of each particle. Particle boards that are strongly adhered to each other by resin adhesives, each particle forming a particle layer by compressing at a high pressure of 20 ~ 50kg / cm2 high pressure that can be compactly compressed to a predetermined thickness by heat-curing resin adhesive It will be prepared.

<Cooling process>

Next, a cooling step (S60) of cooling the particle board 2 is performed.

In the cooling process (S60), when the particle board 2 is compression molded under high temperature and high pressure, the surface is heated and the vapor and gas are less released, so that the particle board 2 is left in the air to release steam and gas to the atmosphere and the particle board 2 Cool naturally until it stabilizes.

<Polishing Process>

Next, the cooled particle board 2 is cut to a specification and the cutting and polishing process S70 is performed to polish the front and back surfaces. Particle board (2) after the cooling process is cut in accordance with the standard, the cut particle board (1) is again polished by sand paper (Sand paper) and the like is smooth and smooth surface and back.

<Corrosion resistant material application process>

Next, the process of manufacturing the corrosion resistant aluminum sheet 3 is demonstrated. In addition to the above-described particle board 1 removal processes, a corrosion resistant paint coating step S80 of applying the corrosion resistant paint 3b to the aluminum sheet 3a is performed.

At this time, as shown in Figures 2 and 3, the corrosion-resistant paint coating step (S80), the first sub-step (S82), which unwinds the wound aluminum sheet (3a) at a constant speed, the unwinded aluminum sheet (3a) The second sub-step (S84) of applying the corrosion-resistant paint (3b) to a uniform thickness on the third, the third sub-step (S86) of drying the corrosion-resistant aluminum sheet (3), and the corrosion-resistant aluminum sheet (3) It is preferably configured by a method of sequentially performing the fourth sub-step (S88) to cut to size.

<Aluminum Sheet Bonding Process>

Finally, the aluminum sheet bonding process (S90) for bonding the corrosion-resistant aluminum sheet 3 to both sides of the particle board (2) is performed. Aluminum sheet bonding process (S90) is performed by applying a resin adhesive on both sides of the particle board (2) and then bonding the corrosion-resistant aluminum sheet (3) can block the penetration of moisture into the particle board (2). Corrosion-resistant impermeable plate material 1 is produced.

At this time, the adhesive applied to both sides of the particle board (2) is preferably used to reduce the amount of formaldehyde that damages the cultural property and does not affect the physical properties of the particle board, the adhesive of the aluminum sheet bonded to both sides of the particle board The thickness is preferably about 0.1mm, and the thicker the thickness, the more flame retardant and impermeable.
