1 to 4, a method of manufacturing a reinforced sheet using a waste box according to an embodiment of the present invention includes collecting a waste box in which a corrugated line is formed in one direction in one direction, A cutting step S20 of cutting the classified waste box into a corrugated cardboard material 10 in the form of a flat plate, and a step of compressing the corrugated board material 10 in the thickness direction (S30) in which an inner plate layer (30) is arranged so that a pair of corrugated cardboard members (10) are staggered in line, and a surface plate layer (30) surrounding the outer surface of the inner plate layer is formed. (S50) for drying the substrate (30).

First, a collection and classification step may be performed (S10).

The carton box for packing can be generally provided with a corrugated cardboard material 10 as shown in FIG. 4, and the corrugated cardboard material 10 may be provided with a surface paper, a back paper, and a corrugated paper 12. Herein, the surface paper and the back paper are collectively referred to as the liner paper 11, and the liner paper 11 and the core paper 12 may be classified according to manufacturer, basis weight, and application.

Particularly, the double-sided cores of the corrugated cardboard 12 have corrugated lines formed therein, and can be classified according to the size of the corrugated cardboard. The bone marrow and the bone height are classified as A, B, C, D, and F, respectively. The bone marrow is 34 ± 2 and the bone height is 4.6 ~ 2.7 mm. Unlike these double-sided corners, double-sided corners can be provided. In this case, they can be classified as AA, AB, etc. according to the combination of double-sided corners.

In the present embodiment, mainly the corrugation 12 of the AB bone, which is a combination of the A and B bones, which is mainly used in the industrial product box or the packaging, is mainly used. In consideration of the compressive strength of the paper pallet and the degree of deformation of the packaging material, A double-sided corrugated cardboard or a single-sided corrugated cardboard may be the object of the present invention, and thus the scope of the present invention is not limited thereto. 3 and 4 illustrate one corrugated cardboard 12 and upper and lower liner sheets 11 forming a single inner core layer in the embodiment of the present invention, One inner core layer is formed of two cores of A and B cores, and the A cores and B cores are shown as a single cores 12 without any distinction between them.

A recycling company that collects waste resources can separate collection boxes for waste paper, that is, waste boxes, which are classified as waste paper. Can be classified according to the type of cornice in the inside of the closed box, or by kind and size.

Thereafter, a cutting step of processing into a corrugated board material may be performed (S20).

The cutting step S20 is a step of cutting the classified waste box into a corrugated cardboard material 10 (see FIG. 4) in the form of a flat plate. The corrugated cardboard is cut into flat plates using a vertical circular cutter The ash 10 may be provided. And can be stacked on the corrugated line of the corrugated board material 10 after being processed into a flat plate shape.

In order to fabricate the reinforcing sheet according to the embodiment of the present invention, a process of laminating at least a pair of inner core plate layers (i.e., two or more corrugated cardboard materials 10) and bonding and pressing them may be performed. That is, a plate layer forming step may be performed in which an inner plate layer disposed alternately on the corrugated lines of the corrugated board material 10 and a surface plate layer 30 surrounding the outer surface of the inner plate layer are formed (S30).

2, the plate layer forming step S30 includes a blending step S31 of blending raw materials of the biodegradable adhesive material layer 20, A coating step S32 of applying the adhesive material layer 20 to both surfaces of the corrugated board material 10 and one surface of the surface plate layer 30 by charging the corrugated board material 10 and the surface plate layer, A lamination step of stacking the surface plate layers 30 so as to be arranged on the upper and lower surfaces of the pair of corrugated cardboard sheets 10 arranged so as to be perpendicular to each other and the respective corrugated lines of at least one pair of corrugated cardboard materials 10 And a pressing step S34 of pressing and pressing both surfaces of the surface plate layer 30 using a flat press (not shown).

The compounding step (S20) is a step of blending the raw material of the biodegradable adhesive material layer (20). The reinforcing sheet 1 (see FIG. 3) produced through the reinforcing sheet manufacturing method according to the present embodiment is a product for eco-friendliness and resource recycling efficiency, and an eco-friendly material can be provided as an adhesive material. To this end, the raw material of the biodegradable adhesive material layer 20 in this embodiment may be prepared by blending 9 to 10% by weight of sodium oxide, 29.4 to 30.4% by weight of silicon dioxide, and 60.1 to 70.1% by weight of water. More preferably, a compound obtained by reacting 9.9 wt% of sodium oxide with 29.9 wt% of silicon dioxide at 20 DEG C and neutralizing the specific gravity to 1400 may be prepared. Such liquid silicate compounds are more environmentally friendly materials and are nature-friendly components and are unlikely to cause environmental pollution during disposal.

Thereafter, the produced raw material can be put into an adhesive storage tank (not shown) of a flat roller laminating machine (not shown).

In the adhesive material layer applying step S32, the raw material is applied to both surfaces of the corrugated cardboard material 10 and the surface paper forming one surface of the surface plate layer 30 so that the adhesive material layer 20 is formed.

The corrugated board material (10) and the surface plate layer (30) can be put into the inlet of the flat roller laminating machine and the raw material can be applied. The waste BOX corrugated cardboard material 10 and the surface plate layer 30, which have been previously cut and spread, are fed into a flat roller joining machine feeding port to uniformly apply the raw material to the surface. As shown in Fig. 3, on both sides of the corrugated board material 10, the raw material can be applied to one surface of the surface plate layer 30. Fig. Here, the surface plate layer 30 may be provided with a reinforcing paper of 400 g or more per square meter of surface area. Compared with conventional paper of 160g and 320g, such reinforced paper has high density and excellent hardness and excellent resistance to external impact and force.

Next, a lamination step may be performed (S33). During lamination, the corrugated lines of the corrugated cardboard material 10 are arranged so as to be offset from each other, so that the compression strength can be improved.

In the laminating step, the inner core plate layer is a pair, and the inner core plate layer may be provided by two corrugated cardboard materials. That is, the corrugated lines of the pair of corrugated cardboard materials 10 are vertically stacked (viewed in a plan view). The surface plate layer 30 can be laminated on the upper and lower surfaces of the pair of corrugated cardboard materials 10, that is, the inner core plate layers 10 and 10, respectively.

Alternatively, the inner core plate layer may be provided by at least two pairs, and the inner core plate layer may be provided by four corrugated cardboard members 10. [ In this case, the angle formed by the line of the corrugation of the corrugated cardboard material 10 of the inner-thickness plate layer adjacent to any one of the inner-thickness plate layers may be 45 degrees.

Through such a plate layer forming step, it is possible to withstand the force and the compressive force applied in the thickness direction of the plate surface more firmly than before, and the strain recovery rate recovered after being deformed can be also excellent. Experimental results on the compressive strength will be described later.

As a final step of the plate layer forming step, a pressing step may be performed (S34). The squeezing step S34 can be performed by placing the upper and lower portions on a flat plate press heated to 50 DEG C, respectively, and then pressing both surfaces of the surface plate layer 30 up and down. In this embodiment, the pressing force is 7 to 8 kgf / cm < 2 > in the vertical direction, and it is preferable that the pressing time is about 100 seconds or more. As described above, if the pressing process is performed after the preheating process of the flat plate press is performed, the adhesion yield can be improved.

Next, as shown in FIGS. 5 and 6, the upper surface of the surface plate layer 30 is subjected to a heat treatment such that the compressive strength in the thickness direction of the inner plate layers 10, 10 and the surface plate layer 30 is improved before the drying step. And a reinforcing member providing step of providing a reinforcing member 40 bent in an L shape along an outer periphery (S40).

The reinforcing member 40 is formed of 400 g or more of reinforcing paper 41 in an area of 1 m < 2 > The reinforcing member 40 may be formed in an L-shaped bent shape and may be adhered along the perimeter of the upper surface of the surface plate layer 30. Thereby, the reinforcing sheet 1 can further improve the compressive strength in the plate surface direction.

Finally, a drying step may be performed (S50). In the drying step, the inner plate layer and the surface plate layer 30 may be dried, and the process conditions of the drying step may be dried at about room temperature for 24 days.

Hereinafter, experimental results of the reinforced sheet manufactured using the method of manufacturing reinforced sheet using the waste box according to the embodiment of the present invention will be described in detail.

The prepared reinforcing sheet 1 has a plate surface size of 1 m 2 and a thickness of approximately 80 100 mm.

(Comparative Example 1)

The inner sheet layer is formed of a wood material, and the surface plate layer is prepared by pressing MDF (compressed wood fiber lumber) with a flat plate press to produce a wood sheet. And is made to have the same plate size and a thickness of about 80 100 mm as in the experimental example.

(Comparative Example 2)

The MDF (compressed wood fiber lumber material) is prepared as the surface plate layer and is pressed by a flat plate press to produce a wood sheet. Then, a biodegradable adhesive material layer is laminated and adhered to each other, and the paper sheet is formed by pressing with a flat plate press. And is made to have the same plate size and a thickness of about 80 100 mm as in the experimental example.

material Maximum load (kg) Compressive strength (kgf / ㎠) Experimental Example 350 1530 Comparative Example 1 375 1650 Comparative Example 2 220 1050

As can be seen from Table 1, the maximum load and the compressive strength were almost equivalent to those of the wood sheet (Comparative Example 1) (the maximum load was about 93% and the compressive strength was about 92%) , And the compressive strength and the maximum load are approximately 1.5 times or more higher than those of Comparative Example 2 produced by laminating the core lines in the same direction.

On the other hand, the cost of the reinforcing sheet 1 made of a closed box can be remarkably reduced.

material Cost (won) Actual Cost (KRW) Experimental Example 300 600 Comparative Example 1 700 1400 Comparative Example 2 700 1400

As shown in [Table 2], compared with the case of conventional wood of Comparative Example 1, even when the cost or actual cost is taken into account, the cost reduction effect is reduced by about 50% .

As described above, the reinforcing sheet manufacturing method according to the present invention makes it possible to utilize the waste box as a material while reducing the production cost and production cost compared to the conventional manufacturing method using the waste box as a material for the pallet and the packaging dumper. Although resources can be recycled using There is an advantage that the force or compressive force applied in the thickness direction of the plate surface is firm and the strain recovery rate recovered after the deformation is not reduced.

Collecting and classifying a waste box in which a line of corners is formed in one direction, and classifying the waste box according to classification and size;
A cutting step of cutting the classified waste box into a corrugated board material in the form of a flat plate;
A step of forming a plate layer in which at least a pair of inner corrugated plate layers arranged in a staggered arrangement of the corrugated lines of the corrugated cardboard material and a surface plate layer surrounding the outer surface of the disposed inner corrugated plate layer are disposed so as to improve the compressive strength and deformation recovery amount in the thickness direction of the corrugated cardboard material; And
A drying step of drying the inner plate layer and the surface plate layer,
Wherein the plate layer forming step comprises:
A blending step of blending a raw material of the biodegradable adhesive material layer;
Applying the raw material, the corrugated cardboard material and the surface plate layer onto a flat roller laminating machine to apply the biodegradable adhesive material layer to both surfaces of the corrugated board material and one surface of the surface plate layer;
A stacking step of stacking the pair of corrugated cardboard members adjacent to each other such that the corrugated lines are perpendicular to each other and the surface plate layer is disposed on the upper and lower surfaces of the pair of corrugated cardboard members; And
And a pressing step of pressing and pressing both surfaces of the surface plate layer using a flat plate press,
Wherein the inner core layer is at least two pairs,
Wherein the inner core layer is made of four corrugated cardboard members,
An angle formed by the line of the corrugation of the corrugated cardboard of the inner-thickness plate layer adjacent to any one of the inner-thickness plate layers is 45 degrees,
Prior to the drying step,
And a step of providing a reinforcing member that is bent in an L shape along an outer periphery of the upper surface of the surface plate layer so as to improve the compressive strength in the thickness direction of the inner plate and the surface plate layer. A packaging cushioning material produced by a reinforcing sheet.
