Description

Method for manufacturing a panel by using waste materials

The present invention relates to a method for manufacturing plywood using waste materials, and more particularly, it is possible to manufacture plywood having excellent heat resistance, water resistance, and flame resistance by using sawdust or PVC powder and synthetic resin material generated when processing wood and PVC plates. It relates to a manufacturing method of plywood using waste materials.

In general, in the manufacture of plywood, the solid wood is cut into a plate, and several of the plate-like wood in which the cut is made are stacked and bonded.

However, such a conventional plywood is a large amount of sawdust is generated when cutting the wood into a plate to contaminate the natural environment, as well as the problem of damaging the forest by requiring a large amount of wood when manufacturing the plywood from the wood. there was.

In addition, the plywood made of wood as described above has a problem of easily deformed and corroded by rainwater due to its low corrosion resistance, as well as easily burned when a fire occurs due to its weak flame retardancy.

Therefore, conventionally, in order to solve the same problem as in the conventional art, only plywood is manufactured and used with a single material resin such as polypropylene or polypropylene.

However, as described above, a plywood made of only a single material resin such as polyproplene or polyethylene is weak in bending strength and external impact, and thus easily deformed, and the weight of the plywood itself becomes heavy. There was a disadvantage.

In addition, the sound insulation and thermal insulation effect can not be expected and there was a problem that the price is also expensive.

An object of the present invention is a waste material collection process for collecting synthetic resin materials, such as PVC powder and vinyl generated when processing sawdust or PVC plate material generated when processing wood, in order to solve the problems as described above, and the collection process The crushing step of grinding the waste materials collected in the fine grinding process, the mixer process of mixing the flame retardant adhesive to the crushed waste material in the crushing process, and the waste material mixture made of mixing with the flame retardant adhesive through the mixer process The molding process is carried out by pressing and kneading into the mold to be molded to a predetermined thickness, the drying step of fixing to prevent deformation of the molded product formed in the molding process, and the molded product that is fixed to prevent deformation in the drying process. By manufacturing the plywood through a cutting process to cut to the specifications of the, to manufacture the plywood It does not require wood, so that the natural environment and forests are not damaged, as well as providing a method of manufacturing plywood using waste materials to make excellent plywood with high flame retardancy, corrosion resistance and water resistance. There is.

Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

In the method of manufacturing plywood using the waste material of the present invention, as shown in Figure 1, waste material collection to collect synthetic resin materials such as PVC powder and vinyl generated when processing sawdust and PVC sheet material generated when processing wood Step 10, a grinding step 20 for pulverizing the waste material collected in the collecting step 10, and a mixer step of mixing a flame retardant adhesive to the waste material pulverized in the grinding step 20 (30) and the molding step (40) of pressurizing and kneading by inserting the waste material mixture mixed with the flame retardant adhesive to a predetermined thickness while the mixer step (30) is molded into a predetermined thickness, and the molding step (40) Cutting process for cutting the molded product adhered to a predetermined standard to prevent deformation in the drying step 50, and to prevent deformation in the drying process. And characterized in that the manufactured through 60.

The present invention constituted as described above collects waste materials generated during processing of a plate such as wood and PVC through a waste material collection process (10), and the waste material collected through the collection process (10) is a crushing process (20). The fine grinding is performed by centrifugation.

At this time, the synthetic resin such as vinyl, etc. are also collected through the collection step 10 at the same time finely crushed through the grinding step 20.

The waste material finely ground in the crushing process 20 is supplied to the mixer process 30 to be mixed with the flame retardant adhesive, and the waste material mixture mixed in the mixer process 30 is a molding process 40 Transfer will take place.

The waste material mixture which has been transferred to the molding process 40 is introduced into an extruder and then kneaded to a predetermined thickness.

At this time, as shown in Figure 2, by installing the mesh type netting 110 in the center portion of the waste material mixture is extruded by the extruder, the binding force of the waste material mixture injected into the extruder is improved state It is revealed that pressure kneading with.

Meanwhile, the molding 120 of the waste material mixture pressurized by a predetermined thickness while passing through the molding step 40 kneaded by the extruder is transported to the drying step 50 and fixed by drying to prevent deformation. do.

The molded product that has passed through the drying step 50 is transferred to the cutting step 60 and then cut into a predetermined size by a cutter or the like to produce the plywood 100.

Therefore, in the present invention, the plywood 100 is manufactured by mixing and fixing waste materials such as sawdust, PVC powder, and various synthetic resin materials generated by processing wood and PVC board with a flame retardant adhesive, thereby making the plywood 100 When manufacturing, it does not require wood, etc., thereby preventing the natural environment and the forest from being damaged, and of course, the plywood 100 has an effect of making excellent plywood having high flame retardancy, corrosion resistance, and water resistance.

As described above, the present invention is a waste material collection process for collecting synthetic resin materials, such as PVC powder and vinyl generated during processing sawdust and PVC plate material generated when processing wood, and waste materials made from the collection process A grinding step of pulverizing finely, a mixer step of mixing a flame retardant adhesive with the waste material pulverized in the pulverizing step, and a waste material mixture mixed with the flame retardant adhesive during the mixer step to be molded to a predetermined thickness. A molding step of pressing and kneading into a mold, a drying step of fixing the molded article formed in the molding step to prevent deformation, and a cutting of the molded article adhered to a predetermined standard to prevent deformation in the drying step. By manufacturing the plywood through the cutting process, it is necessary to use solid wood, etc. when manufacturing the plywood. Not to prevent damage to the natural environment and forests, of course, it is a very useful invention to make excellent plywood flame retardant, corrosion resistance and water resistance.
