The paper manufacturing method described above will be referred to as'this method' for convenience of explanation.

1 to 3, the present method (method for producing a raw paper for fruit tree bags containing phytoncide according to an embodiment of the present invention) comprises a composition step (S1), a papermaking step (S2), a supply step (S3), and It includes a lamination step (S4).

The composition step (S1) includes a step of stirring the raw material 411 including at least one of the pulp 411a and the waste paper 411b into water (hereinafter, a raw material stirring step). The pulp 411a is obtained by extracting the fibers of the plant through mechanical and chemical treatment, and the used paper 411b may mean recycled paper.

The raw material stirring step includes a dissociation process in which the raw material 411 is put into the stirring container 1 containing water to dissolve the raw material 411 in water, and the water and the raw material 411 are mixed in the stirring container 1. It may include a beating process of mechanically cutting the raw material 411 in the raw material 411 by stirring. The raw material stirring step is an important step in determining the quality of the paper 4 produced by this method.

The beating process may be performed by a stirring blade (not shown) rotating in the stirring vessel 1 to stir the water and the raw material 411, which is conventional in the field and a more detailed description thereof will be omitted.

In the present method, the composition step (S1) may include a step of removing foreign substances contained in the raw material 411 (hereinafter, a foreign substance removing step) before the raw material stirring step. The foreign matter removing step may be performed by a supercron, a high vibration screen, or the like.

4 is a view for explaining a drug, and FIG. 5 is a view for explaining a material. 1 to 5, the composition step (S1) is a step of producing a stock material 41 by adding and stirring a chemical 5 including a dye adhesive, a wet forcing agent, and a degassing agent to the raw material 411 (hereinafter The drug injection step) may be included.

Although not shown, the composition step (S1) of the present method may include a step of injecting a dye into the stock material 41 (hereinafter, a dye input step), and the dye adhesive that is introduced into the raw material 411 in the drug input step is To improve the adhesion between the dye and the stock material 41 added in the dye input step, an acrylic monomer may be included as an example.

The wet forcing agent is for improving the strength of the paper 4 in a wet state, and may include a polyamide resin as an example, and the degassing agent is for removing microbubbles in each step of the method. It may contain a compound.

It goes without saying that the chemical (5) used in the composition step (S1) of the present method may contain other additives in addition to a dye adhesive, a wet forcing agent, and a degassing agent.

6 is a view for explaining a paper machine. 1, 5 and 6, in the papermaking step (S2), the paper stock 41 is put into the paper machine 2 and the paper 4 (the first paper 4a, the second paper 4b) is It is a manufacturing step.

The paper machine (2) is a machine that continuously makes paper (4). The papermaking step S2 may include a step of spraying the paper material 41 onto the wire mesh through the wire mesh part 21 of the paper machine 2 (hereinafter, a spraying step). For example, the metal mesh part 21 may include a fan pump that finely sprays the paper material 41 onto the metal mesh.

In addition, the papermaking step (S2) may include a step of dehydrating by pressing the paper stock 41 to the blanket 221 (felt) by the pressing unit 22 (hereinafter, a pressing step). In the composition step (S1), since the raw material 411 is added to water and stirred, the stock material 41 may contain moisture (containing about 80 to 90% moisture). The pressing step is a step for dehydrating the moisture contained in the stock material 41 in the composition step (S1).

Illustratively, the pressing portion 22 may include two press rolls, one of the two press rolls being guided while the paper material 41 is wound and rotated, and the other one of the two press rolls is a blanket 221 ) Is wound and rotated and guided, so that the stock material 41 is pressed against the blanket 221 so that the moisture contained in the stock material 41 is transferred to the blanket 221 so that the stock material 41 can be dehydrated.

In addition, the papermaking step S2 may include a step of drying the paper stock 41 by the drying unit 23 (hereinafter, a drying step). After the pressing step, the stock material 41 may contain about 50% of moisture. When pressing the blanket 221 to further dehydrate the moisture of the stock material 41 in the above-described pressing step, the stock material ( 41) may damage the surface.

Therefore, in the drying step, heat is applied to the stock material 41 to additionally evaporate moisture from the stock material 41 to dry it. Since the moisture in the stock material 41 is dehydrated in the pressing step, the heat applied to the stock material 41 in the pressing step may be less than that in a state without the pressing step.

In the pressing step and the drying step, moisture is dried in the stock material 41 to generate access and hydrogen bonds between fibers, thereby flattening the fibers.

The paper machine 2 includes a gloss part 24 and a winding part 25, and the papermaking step S2 is performed by a step of glossing the paper material 41 by the gloss part 24 and the winding part 25. It may include the step of winding the stock material 41, which is common in the relevant field, and a more detailed description thereof will be omitted. In this method, the paper material 41 is produced as paper 4 through the paper making step S2.

7 is a diagram for explaining a lamination step. 1 and 7, the supplying step S3 is a step of placing the phytoncide 11 on the first paper 4a. More specifically, the phytoncide 11 is placed on one side of the first paper 4a (exemplarily on the top surface of the first paper 4a).

The feeding step S3 can be performed by the feeder 9. The phytoncide 11 may be an extract extracted from cypress trees, for example. When the phytoncide 11 is an extract, the feeder 9 may be a sprayer, and the supply step S3 is performed by the sprayer to perform phytoncide. (11) can be applied to the first paper (4a).

If the phytoncide 11 is a powder as another example, the feeder 9 may be a powder feeder, and the feeding step S3 may be performed by the powder feeder.

1 and 7, the laminating step (S4) is a step of laminating the first paper 4a and the second paper 4b to produce a base paper 10. As described above, it was said that the phytoncide 11 is placed in the first paper 4a, but it is preferable that the side on which the phytoncide 11 is placed in the first paper 4a be laminated facing the second paper 4b. .

The laminating step (S4) may be performed by the laminating machine 6, which may be, for example, a press roll.

As such, the method includes a supply step (S3) of placing the phytoncide 11 on the first paper (4a) and a lamination step (S4) of laminating the first paper (4a) and the second paper (4b). By doing so, it is possible to manufacture the base paper 10 for fruit tree bags having a biocidal effect to combat bacteria, fungi, pests, and pests, and there is no need to apply an insecticide to the base paper 10 to combat diseases and insects. You can prevent pesticides, etc. from remaining on the fruit. In particular, since the phytoncide 11 is placed on the first paper 4a and interposed between the first paper 4a and the second paper 4b, it is possible to suppress the loss of phytoncide 11 in the base paper 10. There is this.

1 and 7, in the laminating step (S4), the laminating machine 6 (as described above, it was said that the laminating machine 6 may be a press roll), and the first paper 4a is transferred to the laminating machine 6 It may be performed by the first transfer roller 7 and the second transfer roller 8 transferring the second paper (4b) to the combiner (6).

The supplying step (S3) can be performed by the feeder 9 dropping a predetermined amount of phytoncide 11 on the first paper 4a transferred from the first transfer roller 7 to the combiner 6 have. As described above, it was said that the feeder 9 may be an atomizer, a powder supply device, and the like. For example, the feeder 9 is on the upper side of the first paper 4a transferred from the first transfer roller 7 to the combiner 6 It can be provided.

In this way, the laminating step (S4) is performed by the combiner 6, the first conveying roller 7 and the second conveying roller 8, and the supply step S3 is performed by the first conveying roller 7 By being carried out by the feeder 9 dropping the phytoncide 11 on the first paper 4a transferred to (6), there is an advantage in that mass production is possible because the base paper 10 can be automatically produced.

FIG. 8 is a view for explaining a coating machine, FIG. 9 is a view for explaining a drying cylinder in the coating machine, and FIG. 10 is a view for explaining a state in which the coating liquid contacts paper moving by the immersion roller in the coating machine.

Referring to FIGS. 8 to 10, the method may include a coating step (not shown) of applying a coating solution to the base paper 10 by the coater 3.

More specifically, the coating machine (3) is disposed between a pair of guide rollers 31 and a pair of guide rollers 31 to move the base paper 10 from the front end to the rear end, and the receiving container in which the coating solution is accommodated. It is provided between the 32 and the pair of guide rollers 31 (provided at the front end of the second guide roll 312 to be described later, and provided at the rear end of the first guide roll 311), and a part of the container 32 It may include an immersion roller 33 immersed in the coating solution accommodated in ).

Here, the front and rear ends are based on the moving direction of the base 10, and the base 10 moves from the front end to the rear end. A unwinding roll on which the base paper 10 produced in the laminating step (S4) is wound is disposed on the front end side of any one (hereinafter, referred to as the first guide roll 311) disposed at the tip of the pair of guide rollers 31, Winding to wind up the base paper 10 that is guided and moved by the second guide roll 312 at the rear end side of the pair of guide rollers 31 at the rear end of the other (hereinafter referred to as the second guide roll 312) Rolls can be placed.

That is, the base paper 10 unwound from the unwinding roll is guided by the first guide roll 311 and moves to the immersion roller 33, is guided by the immersion roller 33, and moves to the drying cylinder 34 to be described later. , It is guided by the drying cylinder 34, moves to the second guide roll 312, is guided by the second guide roll 312, moves to the take-up roll, and the base paper 10 is wound on the take-up roll as described above.

It goes without saying that the moving power of the base paper 10 in the coating machine 3 is the rotation of the winding roll, and the winding roll can be rotated by a motor or the like. The coating machine 3 is to maintain the tension of the paper 4 between the respective rollers (the first guide roll 311, the second guide roll 312, the immersion roller 33, and a drying cylinder 34 to be described later). A driven roller may be additionally arranged.

As described above, the base paper 10 that is wound around the immersion roller 33 and moves to the rear end is immersed in the coating liquid contained in the receiving container 32 so that a part of the immersion roller 33 is in contact with the coating liquid, so that the coating liquid can be applied.

In this way, there is an advantage that the loss of the phytoncide 11 from the base paper 10 can be suppressed by protecting the base paper 10 on which the phytoncide 11 is placed and suppressing the damage of the base paper 10.

1 and 7 to 9, the immersion roller 33 may have a smaller diameter than the guide roller 31. The guide roller 31 is a roller that guides and moves the base paper 10 from the front end to the rear end, and rotates by a central axis having a longitudinal direction from a plane to a rear surface as shown in FIG.

Since the guide roller 31 has a larger diameter than the immersion roller 33 and can move the base paper 10 from the front end to the rear end with less rotation, the guide roller 31 and the base paper 10 There is an advantage in that the number of times of contact and contact release can be reduced, and the life of the guide roller 31 can be extended by reducing friction and shear stress with the central axis.

In addition, since the immersion roller 33 has a smaller diameter than the guide roller 31, when the immersion roller 33 rotates at a speed corresponding to the guide roller 31, a coating solution is more precisely applied to the base paper 10 to prevent phytoncide. There is an advantage of maximizing the effect of (11).

1, 7 to 9, it was said that the coating machine 3 may include a plurality of drying cylinders 34 as described above, but the coating liquid may contain moisture, and the drying cylinder 34 contains the coating liquid. It is to dry the moisture in the applied base (10). As described above, in the case of drying the base paper 10, since it is possible to induce strong hydrogen bonds by facilitating access between the fibers, it is possible to flatten the fibers.

The drying cylinder 34 is for drying the fabric on its surface by passing steam through the rotating cylinder, and since it is commonly used in the relevant field, a more detailed description will be omitted.

A plurality of drying cylinders 34 are disposed at a front end of the second guide roll 312 and at a rear end of the immersion roller 33, but are provided above the immersion roller 33, and a plurality of guide rollers 31 ) Any one disposed at the rear end may be provided above the second guide roll 312.

The base paper 10 moved to the immersion roller 33 through the first guide roll 311 is immersed in the coating solution and then moves to the drying cylinder 34 provided above the immersion roller 33. Moisture from the base paper 10 is evaporated by the drying cylinder 34 to move upward, and the second guide roll 312 disposed at the rear end is disposed below any one disposed at the rear end of the plurality of drying cylinders 34 As the paper 4 moves downward, there is an advantage that it is possible to suppress re-absorption of the evaporated moisture (water vapor) to the paper 4 moving to the rear end after passing through the drying cylinder 34. In addition, since the drying cylinder 34 is disposed above the immersion roller 33 to reduce the length of the coater 3 in the horizontal direction, there is an advantage in that space utilization is increased.

Here, the upper side refers to the upper side based on FIG. 7, the lower side refers to the lower side based on FIG. 7, and the horizontal direction refers to the left and right direction based on FIG. 7.

On the other hand, the present invention includes a base paper 10 including the phytoncide 11 prepared by the present method. The base paper 10 including the phytoncide 11 according to an embodiment of the present invention is manufactured by the present method described above.

The base paper 10 has the effect that the phytoncide 11 is placed in the above-described supply step (S3) to have a biocidal effect to combat bacteria, fungi, pests, pests, and the like. In particular, it has the effect of suppressing the disappearance of the phytoncide 11 through the lamination step (S4).

On the other hand, in the present method, the laminating machine 6 (press roll) performing the laminating step S4 is repeatedly in contact with the first paper 4a, the second paper 4b, and the base paper 10 and released from contact, Since the first paper (4a) and the second paper (4b) are in contact with the high pressure, there is a risk that scratches may occur on the outer surface (therefore, the combiner 6 is formed of a metal material to provide abrasion resistance of the outer surface (surface). Can).

In addition, there is a concern that corrosion may occur in contact with moisture contained in the surface of the first paper (4a), the second paper (4b) and the base paper (10), water vapor in the atmosphere, and moisture during the washing process. .

When corrosion occurs in the combiner 6, stress is concentrated and stress corrosion cracking may occur.If a scratch or the like occurs on the outer surface of the combiner 6 due to repeated use, crack corrosion will occur and the corrosion rate will be accelerated. I can.

In order to suppress the occurrence of the above-described problem, the combiner 6 may include a protective film G provided on the outer surface.

On the other hand, if the laminate 6 is used for a long time with the protective film G applied, it is possible to detect scratches or corrosion on the outer surface of the laminate 6 in real time due to the occurrence of fine grooves in the protective film G. In order to confirm, the protective film G needs to be maintained in a transparent state, and if a groove (hole) occurs for maintenance of the protective film G, it is necessary to confirm this.

As a means to meet the above needs, the protective film (G) is a first transparent adhesive layer (G1) in contact with the outer surface of the laminate (6), and a transparent heating layer (G2) provided on the first transparent adhesive layer (G1). , A second transparent adhesive layer G3 provided on the transparent heating layer G2 and a variable protective layer G4 provided on the second transparent adhesive layer G3.

Each of the first transparent adhesive layer (G1) and the second transparent adhesive layer (G3) is 100 parts by weight of an acrylic monomer composed of 70 to 99% by weight of butyl acrylate and 1 to 30% by weight of acrylonitrile, 0.1 to 5 parts by weight of a radical initiator, and It may contain 0.01 to 20 parts by weight of a crosslinking agent.

Butyl acrylate has a glass transition temperature of 0°C or less when polymerization with a homopolymer, and acrylonitrile has a glass transition temperature of 80°C or more when polymerization with a homopolymer.

If the content of butyl acrylate is less than 70% by weight, the glass transition temperature increases, thereby reducing the impact resistance, and there is a problem that haze occurs. In addition, if the content exceeds 99% by weight, the glass transition temperature is too low, which is not preferable because there is a problem in that abrasion resistance is inferior.

If the content of acrylonitrile is less than 1% by weight, the glass transition temperature is too low, so that adhesion durability decreases, and if the content exceeds 30% by weight, there is a problem that the initial adhesive strength decreases, which is not preferable.

The radical initiator is used for polymerization of the acrylic monomer, and commercially available radical initiators may be used.

The crosslinking agent is added to crosslink the acrylate-based copolymer obtained by polymerizing butyl acrylate and acrylonitrile, and, for example, hexanediol diacrylate may be used. If the content ratio of the crosslinking agent is less than 0.1 parts by weight, the sheet becomes flexible and the cutting property decreases, resulting in a decrease in productivity, and if the content ratio exceeds 20 parts by weight, it becomes hard and the impact resistance decreases, and there is a problem of crushing, which is not preferable. .

Each of the first transparent adhesive layer G1 and the second transparent adhesive layer G3 may maintain an adhesive force at a high temperature while maintaining a transparent state. It goes without saying that the first transparent adhesive layer G1 and the second transparent adhesive layer G3 maintain adhesive strength at high temperatures (about 37°C or higher) and may contain other commercially available additives on the premise of maintaining a transparent state.

The transparent heating layer G2 is provided on the top of the first transparent adhesive layer G1 to be described later, and is disposed between the first transparent adhesive layer G1 and the second transparent adhesive layer G3, and is indium tin oxide. ), but it generates heat when DC or AC electricity is applied, and is characterized by being transparent.

The variable protective layer (G4) is provided on the second transparent heating layer (G2), and a first solution in which 3.84 g of N-isopropyl acrylamide (NIPAM) polymer and 1.25 g of sodium alginate are dissolved per 250 ml of distilled water, and A converting agent in which a second solution containing 3% calcium chloride and 0.5% ammonium persulfide is mixed in 300 ml of distilled water, and 5 to 30 parts by weight of methyltrimethoxysilane, 20 to 75 parts by weight of colloidal alumina, 30 parts by weight of isopropyl alcohol It may contain a protective agent containing less than parts.

The first solution and the second solution are each degassed with nitrogen gas, and the first solution is added dropwise by a syringe to the stirred second solution, and at the same time as the dropping, fine particles containing calcium alginate as macrocapsules are generated. . The polymerization of the enclosed NIPAM is terminated within 1 to 3 hours, and the obtained fine particles can be washed 3 to 7 times with distilled water.

Such a converting agent is present in a transparent state at about 37°C or less, and in a state exceeding 37°C, the uncrosslinked polymer is insoluble in the fine particles and becomes cloudy, so it is converted to an opaque state. If it goes down again below 37℃ from the insoluble state, the converting agent is converted to a transparent state, and the transparent and opaque state may be reversibly changed.

5 to 30 parts by weight of methyltrimethoxysilane, 20 to 75 parts by weight of colloidal alumina, and 30 parts by weight or less of isopropyl alcohol may be mixed by stirring for about 1 hour and then subjected to ultrasonic dispersion treatment. It has excellent abrasion resistance, chemical resistance, corrosion resistance, weather resistance, and thermal stability.

As described above, the laminate 6 has an advantage that scratches, corrosion, etc. can be suppressed by being provided on the outer surface of the protective film G including a protective agent having excellent wear resistance and corrosion resistance.

As described above, as the combiner 6 is used for a long period of time with the protective film G provided on the outer surface, the protective film G may generate fine grooves due to external force. (6) Scratches and corrosion may occur on the outer surface.

As described above, the protective film (G) is maintained in a transparent state at 37°C or less (see [A] of Fig. 11), so that scratches, corrosion, etc. have occurred on the surface of the combiner 6 equipped with the protective film (G) in real time. It can be confirmed by

As described above, in order to confirm in advance that the protective film G has been provided (attached) to the outer surface of the combiner 6 and used for a long time, the groove of the protective film G has occurred, or on the outer surface of the combiner 6 In a state where it is confirmed that damage such as scratches and corrosion has occurred, it is necessary to check the location of the grooves in the protective film G for maintenance of the protective film G.

At this time. When electricity is applied to the transparent heating layer (G2), the transparent heating layer (G2) is heated to transfer heat to the changing agent, and when the changing agent exceeds 37°C, the variable protective layer (G4) containing a protective agent becomes cloudy. It becomes opaque. On the other hand, the first transparent adhesive layer (G1), the transparent heating layer (G2), and the second transparent adhesive layer (G3) maintain a transparent state, and the color of the paper machine 6 that was in an opaque state and a cloudy variable protective layer ( The color of G4) is contrasted (see [B] of Fig. 11), so that the location of the groove, etc. in the variable protective layer G4 can be easily identified (the color of the outer surface of the laminate 6 and the variable protective layer in an opaque state) It is preferable that the color of (G4) is different).

As described above, since the second transparent adhesive layer (G3) maintains adhesive strength even at a high temperature exceeding 37°C, the variable protective layer (G4) is formed in the grooves generated in the variable protective layer (G4) attached to the outer surface of the combiner (6). ), it can be easily maintained and repaired.

As described above, by including the protective film G4, which is easy to maintain, the combiner 6 has an advantage that it is possible to suppress the occurrence of scratches, corrosion, etc. on the outer surface of the combiner 6 for a long period of time.

The present invention described above with reference to the accompanying drawings can be variously modified and changed by a person skilled in the art, and such modifications and changes should be construed as being included in the scope of the present invention.
