DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like elements throughout.

2 to 4, a fiber plywood slate 100 according to a preferred embodiment of the present invention includes: a plurality of fiber plywood 200 formed by processing waste synthetic fibers 210; And a resin plywood 300 formed by processing the waste synthetic resin 310. The resin plywood 300 is molded so as to have a predetermined cross-sectional shape in a state of being interposed between the plurality of fiber plywood 200 to complete the fiber plywood slate 100.

The waste synthetic fibers 210 constituting the fiber plywood 200 may be formed of a first waste synthetic fiber which is a mixture of one or both of a polyethylene fiber and a polypropylene fiber and a second waste synthetic fiber which is a mixture of nylon fibers, acrylic fibers, polycarbonate fibers, A vinyl chloride fiber, a vinyl chloride fiber, and a polystyrene fiber.

However, it is preferable that the waste synthetic fibers are constituted by mixing the second waste synthetic fibers at a ratio of 186 parts by weight to 100 parts by weight of the first waste synthetic fibers. The process of composing waste synthetic fibers by mixing the first waste synthetic fibers and the second waste synthetic fibers is performed by a sorter 220.

The waste synthetic fibers 210 constituted by the sorting device 220 are transferred to the pulverizer 230 side and cut to a certain size by the pulverizer 230. At this time, the waste synthetic fiber 210 is preferably pulverized to a size of 5 x 5 cm.

Then, the pulverized waste synthetic fibers 210 are transferred to the side machine 240, and are rubbed by the machine 240 to form a felt. The felt preferably has a thickness of 3 to 5 mm.

Next, the felt composed of the waste synthetic fibers 210 is punched by the punching machine 250 in the form of a plurality of overlapping layers, thereby forming a single layer of overlapping felt composed of a plurality of felt layers. Preferably, the overlapped felt is formed by punching a felt layer overlaid with 5 to 7 layers. At this time, air is removed from the overlapped felt by the punching operation, and the overlapped felt is thinned to a certain thickness.

Thereafter, the overlapped felt is transferred to the heater 260, and the overlapped felt is heated to 250 ° C by the heater 260. At this time, waste synthetic fibers having a melting point lower than 250 占 폚 among the synthetic fibers constituting the overlapped felt are melted and penetrate into other waste synthetic fibers.

Subsequently, the overlapping felt, in which the melt of the waste synthetic fibers having a low melting point is infiltrated between the waste synthetic fibers, is transferred to the heating and pressing roller 270 side, and is heated under the conditions of a temperature of 200 캜 and a pressure of 300 kg / And is heated and compressed by a roller (270).

Thereafter, the waste paper 310 is conveyed to the heating and pressing roller 350 side, and is heated and compressed under the conditions of a temperature of 200 ° C and a pressure of 300 kg / cm 2 to form a waste waterproof panel. At this time, since the waste paper 310 is heated and compressed at a lower temperature in the heater 340, the waste paper liquid that has permeated through the solid waste paper is cooled to bind the solid waste paper.

Subsequently, the waste water-absorbing panel is transferred to the cooling roller 360 side, and cooled at a temperature of 14 캜. Then, the waste water receiving panel is transferred to the forming roller 370 side. The forming roller 370 applies a pressure of 500 kg / cm 2 to the wastewater panel to complete the resin plywood 300 having a thickness of 1 to 2 mm.

At this time, the resin plywood 300 is partially melted, and the fiber plywood 200 and the resin plywood 300 are fused to form a single panel. The fiber-resin composite panel thus formed is conveyed to the cooling roller 120 side.

In the step (S400) of cooling the fibrous resin composite panel, the fibrous resin composite panel is cooled to a temperature of 14 캜 by the cooling roller (120). Thereafter, the fibrous resin composite panel is transferred to the forming roller 130 side.

In the step S500 of completing the fiber plywood slate, the fiber composite composite panel is molded to have a corrugated cross section under a pressure of 500 kg / cm2 by a forming roller 130, or is formed into a flat plate shape, Slate 100 is completed.

The method of fabricating a fiber plywood slate according to a preferred embodiment of the present invention may further include cutting the fiber plywood slate 100 to a predetermined length (S60).

As described above, by producing the fiber plywood slate 100 by laminating the resin plywood 300 between the fiber plywood 200, the bending strength of the fiber plywood slate 100 is significantly increased and the amount of force strength deformation is reduced.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope of the invention as claimed. It can be improved.
