DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to embodiments and drawings. The drawing used here is FIG. FIG. 1 is a conceptual diagram showing a recycling system including an embodiment of the present invention. (Preparation of material for molding) First, a new pellet is prepared. The new pellets are pellets obtained by mixing fixed grains formed of a cellulose material with a resin.
The formation of "fixed grains" is based on the PCTJ described in the prior art.
Produced by the technique described in P94 / 00351. That is, the pulverization is performed by fixing a surface particle having a smaller diameter and harder than the particle on the surface of the particle having a higher bulk specific gravity by further pulverizing the pulverized powder obtained by pulverizing the cellulose material.
As the cellulosic material at this time, scraps, sawdust, and the like that are generated when wood is cut or cut for use as a part of a house, furniture, or the like can be used. The production of the pellet is a conventionally known method, for example,
Pigment and fixed particles are mixed and melted in the resin, and the resin is extruded in a string form from a perforated circular nozzle and cut. The resin used here was a vinyl chloride resin or a foamed vinyl chloride resin. When a foamed vinyl chloride resin is used, the foaming rate of the regenerated molded product is lower than that of a new product.

Next, a regenerated pellet is prepared separately from the new pellet. The material of the regenerated pellets is a defective material obtained by extrusion molding, a cut end obtained by cutting or cutting after molding, and a material that can be reused among those discarded after painting or bonding. These are collected and pulverized, and if necessary, re-pulverized after classification and melted to form pellets. The pulverizing means uses, for example, a hammer mill so that the size is about several centimeters to several millimeters. In addition, in the cut end by cutting or cutting after molding, a material having a size equal to or less than a certain size may be directly used as a material of a molded product without being pelletized.

The new pellets and the regenerated pellets are prepared so as to have at least two kinds of colors.
Specifically, a pellet is formed after adding a pigment to one or both of a new pellet and a regenerated pellet. The pigment is selected from inorganic pigments such as iron oxide and carbon black in accordance with the color desired by the final molded article.
Select one or several types to use. (Molding and Subsequent Processing) When pellets can be produced or crushed pieces to be added as they are are prepared, they are melted and extruded to produce wood-like molded articles. Depending on the type of the final product, vacuum molding or compression molding may be performed.

On the other hand, defective pellets produced in pellet production, defective extruded materials in extrusion molding, cut ends produced in cutting / cutting processing, waste products produced in painting / adhesion processing, etc. are separated as necessary. It is crushed and pelletized again, or becomes a molding material as it is. Painting·
Waste products generated in the bonding process are separated into non-defective products and non-defective products. Good products can be crushed and immediately pelletized, but the used adhesives and paints may cause harm when producing recycled products. (Recovery and Sorting) Residential waste materials that were once produced and shipped after being discarded, and defective products that cannot be directly reused among the waste products that were produced during painting and bonding, were collected as recovered materials. They are separated into iron, aluminum, wood pieces, plastic materials, etc. and recycled or discarded.

Among these, the plastic material is ground and classified using a hammer mill, for example, to a size of several centimeters to several millimeters. Products of a certain quality are pelletized again, used as a molding material as they are, or subjected to thermocompression molding to be reprocessed into mosaic molded products before being shipped. If the quality after rework is likely to be low, it is re-formed into a part that cannot be seen directly, for example, a base material. Here, the reshaped base material generally has a characteristic that the coefficient of thermal expansion is lower than that of a new molded product, and may be suitable for use in a portion where a temperature change is large.

As a means of classification performed in association with the pulverization, various means can be adopted in addition to the size classification using the principle of sieve. The criterion for this classification is appropriately adjusted depending on the desired quality of the product, production convenience, and the like. (Heat Compression) When manufacturing a mosaic-shaped molded product by thermocompression molding, if the size of the mosaic-like grains is to be increased, the standard is increased. If the crushed pieces are too small for the material of the mosaic pattern product, the heat energy required for melting is not so large. In some cases,
Thermal energy required for fabrication can be saved. The completed mosaic pattern molded product is made up of mosaic pieces having different shapes and sizes, and can provide a tasteful molded product in which the same product does not exist. In addition, a mosaic pattern product obtained by using only a wooden plastic product as a material, pulverizing the material, and thermally compressing the product can provide a quaint molded product as if a wooden piece was used as a mosaic piece. Furthermore, wood plastic is PCTJP94 / 0035
If it is produced by the technique described in No. 1, it will be a molded product of a mosaic piece closer to a real wood piece. When a product using vinyl chloride as a resin is pulverized and hot-pressed to be molded, the temperature is 150 ° C. to
The desired mosaic-shaped molded product was obtained at a temperature of 00 degrees and a pressure of 10 kg / cm 2. Depending on conditions such as the type of resin used as the material of the molded article, when vinyl chloride is used as the resin, the temperature may be 100 to 200 degrees Celsius and the pressure may be 5 kg or more / square centimeter.

Further, in the present embodiment, the surface of the mosaic pattern product 10 as such a molded product is embossed, and a plurality of grooves 21 are formed.
As shown in FIG. 2, the embossing process is performed by an embossing device 30 including a rotating shaft 31 and a cylindrical embossing roller 32 rotatable around the rotating shaft 31. On the peripheral surface of the embossing roller 32, a number of projections 33 for forming the groove 21 are provided. The height of the projection 33 is about 1 mm. The depth of the groove 21 is equal to or less than the height of the protrusion 33.

The length of the emboss roller 32 in the circumferential direction is the same as the length of the mosaic pattern product 10 formed in a plate shape in the length direction. The embossing device 30 is arranged such that the direction of the rotating shaft 31 of the embossing device 30 and the length direction of the wood-like molded product 10 are perpendicular to each other, while pressing the emboss roller 32 against the wood-like molded product 10 from above. By rotating, the uppermost processed plate 11 is embossed.

Thereafter, if it is necessary to connect a plurality of mosaic pattern products 10 along the length direction, the plurality of mosaic pattern products 10 are closed. Although illustration is omitted, in the present embodiment, the cutting is performed by the actual processing of the tongue and groove processing. When the embossing process is completed, the process proceeds to a sealer application process, if necessary. In the present embodiment, in this sealer application step, a color sanding sealer is applied on the surface of the mosaic pattern product 10 on which embossing has been performed, and the surface of the mosaic pattern product 10 including the plurality of grooves 21 is applied. Color on top.

Accordingly, the inside of the groove portion 21 is filled and colored by the sealer coating, and an intermediate coating which is a prerequisite for the subsequent coating process is performed by the sealer coating. By the sealer coating, the color sanding sealer accumulated in the groove 21 formed by embossing forms a pattern on the mosaic pattern product 10. When the sealer application step is completed, the process proceeds to the following polishing step.

In some cases, wiping coloring may be performed instead of the above-mentioned sealer coating step.
Wiping coloring processing is a processing method in which a dye is applied, then wiped before drying, and only the concave portion is colored. Therefore, when the wiping coloring process is performed as described above, the plurality of grooves or recesses formed by the embossing process are colored. As a result, when the wiping coloring process is performed, it is possible to manufacture a recycled product having an appearance more similar to cork or the like.

Then, in the polishing step, the surface of the wood-like molded product subjected to the sealer coating or the wiping coloring process is polished. For this polishing operation, a polishing apparatus provided with a rotating shaft and a cylindrical polishing roller that can rotate in the reverse direction around the rotating shaft is used (not shown). In the present embodiment, sandpaper having a normal roughness is used for the polishing roller.

In performing the polishing operation, the polishing is performed while extruding the mosaic pattern product 10 along the rotation of the polishing roller. When the first polishing of the mosaic pattern product 10 is completed, the polishing roller rotates in a direction opposite to the first polishing,
A second polishing is performed. By rotating the polishing roller in the reverse direction, the polishing can be performed twice while the mosaic pattern product 10 makes one reciprocation.

By this polishing step, the unevenness of the coating film formed on the surface of the mosaic pattern product 10 by the sealer coating and the slight unevenness of the surface of the mosaic pattern product 10 are deleted, and a smooth coating base surface is formed. . In addition, when the mosaic pattern product 10 has an extra color other than the wood grain, it is deleted in this polishing process, and the wood grain pattern and the pattern made of the color sanding sealer adhered in the groove are formed on the surface of the mosaic pattern product 10. appear. Even in the case where the wiping coloring process is performed, similarly, the surface portion is polished in the polishing step, and the dye only in the concave portion remains, and as a result, an appearance similar to cork appears on the surface of the mosaic pattern product 10.

In this embodiment, the polishing operation was performed by changing the position of the mosaic pattern product 10 without moving the position of the polishing roller, but rotating the polishing roller without changing the position of the mosaic pattern product 10. It may be moved while moving. Further, in the present embodiment, the polishing operation is performed twice by reciprocating the mosaic pattern product 10 once, but the mosaic pattern product 10 or the polishing roller may be moved two or more times. By making one reciprocation, the polishing operation can be performed an odd number of times, such as performing three polishing operations.

When the above polishing step has been completed, the process proceeds to the painting step. The coating step according to the present embodiment is divided into an intermediate coating operation step and a top coating operation step. In the intermediate coating operation step, the color sanding sealer is applied again to the entire surface of the mosaic pattern product 10 as in the sealer coating step. In this case, for example, when a floorboard is formed from the mosaic pattern product 10, a lubricant is also used to improve abrasion resistance. If necessary, a UV coat is applied before and / or after the intermediate coating.

When the intermediate coating work process is completed,
Move on to the overcoating work process. In the overcoating operation step, the surface of the mosaic pattern product 10 is coated. That is, for example, a top coat is applied with a urethane resin-based paint, specifically, clear urethane, and finally, a UV coat is applied on the top coat to cure the top coat.

The mosaic pattern product 10 manufactured by the above-described manufacturing process can obtain a clear and good mosaic pattern with good appearance quality without using a decorative board as in the related art. In addition, for example, when a floorboard is formed by the mosaic pattern product 10, even if the caster gets over any hard object while moving furniture with casters on the floorboard, the floorboard material is formed on the surface. Only the applied UV coat or topcoat is scratched.

On the other hand, although the UV coat and the top coat are applied, the colored pattern is also formed by the grooves formed by embossing, so that the user can feel the feeling of wood more than the floorboard using decorative plywood. Can be. In the above embodiment, the case where the coating step is formed by the intermediate coating operation step and the top coating operation step has been described as an example, but is not limited to the above embodiment, and the intermediate coating operation step It can be omitted.

In the case of going through the intermediate coating work step in the coating step as in the present embodiment, it is possible to apply a higher quality coating. In addition, between the embossing step and the sealer applying step, a step of removing fine irregularities caused by embossing on the surface of the mosaic pattern product 10 using a special coarse sandpaper may be further provided. Good.

When such a step is provided, the mosaic pattern product 10 having a smoother surface is formed, and the appearance quality can be further improved. In addition, a step of mixing a rubber material at a predetermined ratio into the mosaic pattern product 10 configured as described above may be provided. As described above, when the rubber material is mixed in the mosaic pattern product 10 at a predetermined ratio, the mosaic pattern product reproduced and manufactured is formed as a laminated composite material with the rubber material. In this case, by appropriately changing the mixing ratio of the rubber material, a mosaic pattern product having a rubber layer formed with an appropriate thickness can be produced.

As a result, in the manufacturing technology of the plastic material product, it is possible to provide a recycled product having a rubber layer which maintains a certain quality without generating plastic material dust by performing the recycling efficiently. Thus, it is possible to provide a reproduction system that can reduce the manufacturing cost. Further, a water draining step for previously discharging the water contained in the plastic material once manufactured using the resin as a base material, and a preheating step for preheating before the heat compression step may be provided.
