Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an extruded material containing waste resin and woody waste material, and particularly to an extruded material having good formability.

[0002]

[Background technology]

 Conventionally, pulverized powder obtained by pulverizing a cellulose material is mixed with a resin, etc., and molded into a desired shape by extrusion molding or injection molding. Forming goods was done. The above-mentioned cellulosic materials used scrap wood and sawdust of architectural wood members.However, from the viewpoint of effective use of resources and environmental protection, once used building panels were collected as building materials, It has become desirable to crush the recovered building components and use them again as raw materials.

[0003] An example of a method for producing a wood-like molded product using a pulverized powder obtained from such collected building members such as building panels as a raw material is described in, for example, JP-A-11-129223. The technology is known. This technology involves recovering wood-based recovered wood components from a building component and recovering resin components made of resin, mixing the recovered wood components and the recovered resin components, and crushing the mixture in the mixing process. And a kneading step of kneading the pulverized powder obtained in the pulverizing step, and a molding step of extruding or injection molding the kneaded material in the kneading step. .

[0004]

[Problems to be solved by the invention]

 Meanwhile, in the kneading step described in JP-A-11-129223, the pulverized powder of the collected wood member and the collected resin member obtained in the pulverizing step is kneaded so as to be uniformly distributed, and the mixed material is extruded in the forming step. It is molded into a desired shape by a machine or an injection molding machine. However, since the mixed material is directly injected into a hopper of an extrusion molding machine or an injection molding machine and molded, the pulverized powder of the recovered wood member and the pulverized powder of the recovered resin member are formed by a difference in specific gravity. It cannot be separated and uniformly mixed in the hopper of the machine, and furthermore, the dust is scattered from the hopper and the content fluctuates, so that molding is impossible, and therefore, a wood-like molded product can be easily manufactured. could not. Therefore, the pulverized powder of the recovered wood member and the recovered resin member is kneaded so as to be evenly distributed, and the mixed material is once melted by an extruder to produce an extruded material. It is desired to produce a wood-like molded product in which the material is further melted and formed into a desired shape.

[0005] Here, when manufacturing the extruded material, a mixed material of the pulverized powder of the recovered wood member and the pulverized powder of the recovered resin member is put into a hopper of an extruder and softened and melted in a heating cylinder. After extruding with a screw and injecting the molten mixed material into the mold, the mixture is cooled and solidified. However, when the mixed material is extruded with a screw, if the fluidity of the mixed material is high, friction between the mixed material and the screw hardly occurs even when the screw is rotated. It is difficult to extrude the mixed material, while if the fluidity of the mixed material is low, the friction generated between the mixed material and the screw is large even when the screw is rotated, so that the screw takes time and energy to extrude the mixed material. Required, and both have poor moldability. Therefore, it is desired to use a mixed material with appropriate fluidity. The present invention has been made in view of the above circumstances, and it is possible to improve the recycling rate of waste material by using the waste material, and at the same time, to extrude by using a mixed material having an appropriate fluidity. It is an object of the present invention to provide an extruded material having good moldability.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the invention of claim 1 is obtained by, for example, crushing waste resin resin obtained by crushing waste resin and wood waste material as shown in FIG. It is characterized in that it is made by mixing wood pulverized wood waste powder into a mixed material, and the mixed material is melted and formed.

According to the invention of claim 1, the crushed waste resin material is mixed with the pulverized wood waste material powder to form a mixed material, and the mixed material is melted and molded. And the pulverized wood waste material are sufficiently dehydrated during kneading to reduce the specific gravity to form a uniformly mixed molded product. That is, if the waste resin pulverized material and the woody waste material pulverized powder are to be directly molded, they cannot be separated and uniformly mixed in the hopper of the molding machine due to a difference in specific gravity, and further, dust is scattered from the hopper. However, in the present invention, the extruded material is manufactured in this way, and the extruded material is further melted and formed into a required shape. In addition, a wood-like molded product used as a building material for a house can be obtained. In addition, since the waste resin and the wood waste are reused, they are excellent from the viewpoint of effective use of resources and environmental protection.

According to a second aspect of the present invention, as shown in FIG. 2, for example, in the extruded material according to the first aspect, the waste resin is obtained by mixing a thermoplastic resin, a thermosetting resin, and impurities. A waste material-mixed resin, wherein the waste material-mixed resin is coarsely pulverized to 20 mm or less to obtain a coarsely pulverized waste material-mixed resin; the waste material-mixed resin coarsely-pulverized product; the pulverized thermoplastic resin; Are mixed to form a mixed material, and the mixed material is melted and molded.

According to the invention of claim 2, the hard-to-melt waste material mixed resin mixed with the thermosetting resin and the impurities is roughly pulverized to 20 mm or less to obtain a roughly pulverized waste material mixed resin. The mixture is made by mixing the pulverized thermoplastic resin with the pulverized wood waste material to form a mixed material, and the mixed material is melted and molded.Therefore, the pulverized waste resin mixed resin, thermoplastic resin, wood waste material Each of the pulverized powders is sufficiently dehydrated at the time of kneading, and has a low specific gravity to form a uniformly mixed molded product.

[0010] In other words, if the raw material mixed resin coarsely pulverized material, thermoplastic resin, and woody waste material pulverized powder are directly molded, they cannot be separated and uniformly mixed in the hopper of the molding machine due to the difference in specific gravity. In addition, dust is released from the hopper and the content fluctuates, which makes molding impossible.However, in the present invention, an extruded material is manufactured in this way, and the extruded material is further melted to obtain a required shape. Since it is molded into a shape, a wood-like molded product used as a building material for a house can be easily obtained. As described above, extruded materials are manufactured from waste wood-mixed resin obtained by mixing easily meltable thermoplastic resins, hard-to-melt thermosetting resins, and impurities, and wood-like waste products are further manufactured. As a result, the recycling rate of waste materials can be improved.

According to a third aspect of the present invention, for example, as shown in FIG. 3, in the extruded material according to the first aspect, the waste resin is obtained by mixing a thermoplastic resin, a thermosetting resin, and impurities. A waste material-mixed resin, wherein the waste material-mixed resin is roughly pulverized to 20 mm or less to obtain a coarsely pulverized waste material-mixed resin, and the coarsely pulverized waste material-mixed resin is fused and solidified to obtain a solidified waste material-mixed resin; The solidified waste material mixed resin is pulverized into a solidified pulverized powder, and the solidified pulverized powder, the pulverized thermoplastic resin, and the woody waste pulverized powder are mixed to form a mixed material. Is melted and molded.

[0012] According to the invention of claim 3, the hard-to-melt waste mixed resin mixed with the thermosetting resin and the impurities is coarsely pulverized to 20 mm or less, and then solidified by fusing. It is made into a mixed material by mixing the pulverized thermoplastic resin and the pulverized wood waste material into a mixed material, and the mixed material is melted and molded. Each of the pulverized powder, the thermoplastic resin, and the pulverized wood waste material is sufficiently dehydrated during kneading to have a low specific gravity, thereby obtaining a uniformly mixed molded product.

[0013] In other words, if it is attempted to directly mold the crushed waste material mixed resin, thermoplastic resin, and crushed wood waste material, they cannot be separated and uniformly mixed in the hopper of the molding machine due to their specific gravity differences. In addition, dust is released from the hopper and the content fluctuates, which makes molding impossible.However, in the present invention, an extruded material is manufactured in this way, and the extruded material is further melted to obtain a required shape. Since it is molded into a shape, a wood-like molded product used as a building material for a house can be easily obtained. As described above, extruded materials are manufactured from waste wood-mixed resin obtained by mixing easily meltable thermoplastic resins, hard-to-melt thermosetting resins, and impurities, and wood-like waste products are further manufactured. As a result, the recycling rate of waste materials can be improved.

Further, since the waste material mixed resin is roughly pulverized to 20 mm or less, then fused and solidified, further pulverized into a solidified pulverized powder, mixed, melted and molded. As compared with the second aspect, the thermosetting resin, the impurities, and the thermoplastic resin can be uniformly mixed without being separated, and the moldability is improved.

According to a fourth aspect of the present invention, in the extruded material according to any one of the first to third aspects, the mixed material is melted at 180 to 200 ° C. and molded.

According to the invention of claim 4, since the mixed material is melted at 180 to 200 ° C. and molded, the pulverized wood waste material in the mixed material is not changed by heat, and The waste resin can be sufficiently melted and softened to be uniformly mixed with the pulverized wood waste material, thereby improving the moldability during extrusion molding.

Here, the reason why the molding temperature is set to 180 to 220 ° C. is that if the molding temperature is lower than 180 ° C., the waste resin is insufficiently softened, so that it is difficult to uniformly knead with the wood waste material pulverized powder. This is because the pulverized wood waste material causes a change such as carbonization by heat.

According to a fifth aspect of the present invention, in the extruded material according to any one of the first to fourth aspects, the mixed material is melted by an extruder and extruded.

According to the invention of claim 5, since the mixed material is melted and extruded by an extruder, the waste resin in the mixed material and the pulverized wood waste material are uniformly mixed. It becomes a solidified extruded material. Therefore, a wood-like molded product can be easily obtained by further melting and molding this extruded material.

According to a sixth aspect of the present invention, in the extruded material according to the fifth aspect, the melt index of the waste resin is 3 g / 10 min or less.

According to the invention of claim 6, since the melt index of the waste resin is 3 g / 10 min or less, the waste resin is mixed with the pulverized wood waste powder and melted to obtain an appropriate fluidity. It can be a mixed material having a property.

That is, the reason why the melt index of the waste resin is set to 3 g / 10 min or less is that when the melt index of the waste resin exceeds 3 g / 10 min, the flowability of the waste resin becomes high, When extruding the mixed material composed of the resin and the pulverized woody waste material with the screw of the extruder, even if the screw is rotated, friction between the mixed material and the screw hardly occurs. This is because it is difficult to extrude and the moldability is poor. Therefore, in the present invention, by setting the melt index to 3 g / 10 min or less, a mixed material having an appropriate fluidity is obtained, and is easily extruded by a screw, so that the moldability is improved.

The term “melt index” as used herein refers to the number of grams of resin extruded per 10 minutes measured under a load of 1.0 kg at 180 ° C.

According to a seventh aspect of the present invention, in the extruded material according to any one of the first to sixth aspects, the waste resin is 36 to 86 wt% and the woody waste is 10 to 60 wt% based on the entire extruded material. It is characterized by being included.

According to the invention of claim 7, since the wood waste material can contain a large amount of wood waste material by including 10 to 60 wt% in the entire extruded material, it is closer to real wood. It can give a touch and texture. In addition, by including the waste material resin in an amount of 36 to 86 wt%, the amount of waste material to be used increases, and the reuse rate of waste material can be improved.

Here, the reason why the wood waste material is included in the extruded material in an amount of 10 to 60 wt% is that if it is less than 10 wt%, it is difficult to give a feeling such as touch to real wood, and 60 wt% is used. Exceeding this will result in excessive amounts of wood waste, which will reduce the extruded material's formability. In addition, the reason why the waste resin is included in the extruded material in the range of 36 to 86 wt% is that it is difficult to improve the recycle rate of the waste material if it is less than 36 wt%, and it is difficult to melt the waste resin if it exceeds 86 wt%. This is because the extruded material contains a large amount and the moldability of the extruded material is reduced.

It is characterized in that the mixed material is melted and molded.

According to the invention of claim 26, the pulverized wood waste material, the pulverized waste resin powder, and the weak anion exchange resin are mixed to form a mixed material, and the mixed material is melted. Since it is molded, that is, in the resin that is melted and molded, there is pulverized wood waste material, so that all of the weak anion exchange resin is covered by the resin and functions as an ion exchange resin. Without any loss, the part close to or in contact with the pulverized wood waste will have the function of an ion exchange resin. Then, the anion in the weak anion exchange resin is ionized by the moisture in the pulverized wood waste material, and this anion is exchanged for the anion contained in the pulverized waste wood resin.

That is, for example, when the waste resin pulverized powder contains nitrate ions that generate odor, the nitrate ions are exchanged with the anions of the weak anion exchange resin and removed.

Here, the reason why the wood waste material pulverized powder is contained in an amount of 30 to 60 wt% based on the whole extruded material is that if it is less than 30 wt%, it is difficult to give a feeling such as a touch closer to real wood, and it is difficult to obtain a texture of 60 wt%. %, The amount of wood becomes excessive and the formability of the extruded material decreases. The reason why the waste resin pulverized powder is contained in the extruded material in an amount of 20 to 69 wt% is that if it is less than 20 wt%, the recycle rate of the waste material cannot be improved. This is because impurities that are difficult to melt in the powder are increased, and the extruded material has poor moldability. Furthermore, the reason that the weak anion exchange resin is contained in an amount of 1 to 20 wt% with respect to the whole extruded material is that if it is less than 1 wt%, the amount of the weak anion exchange resin is too small, so that the function as an ion exchange resin is sufficiently performed. If the content exceeds 20% by weight, a large amount of weak anion exchange resin is contained, so that a wood-like molded article having a woody feel cannot be obtained.

[0077]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The extruded material according to the first embodiment of the present invention includes a crushed waste resin material obtained by crushing a waste resin, a crushed wood waste material powder obtained by crushing a wood waste material, and the wood waste material. A mixed material is prepared by mixing maleic anhydride as an adhesion aid between the powder and the pulverized waste resin material, and a pigment, and the mixed material is melted and molded.

The waste material resin is obtained by crushing a tray collected after being used for packaging of foods and the like, a polypropylene packaging member such as a food container, and polypropylene scraps generated when the polypropylene packaging member is formed. is there. As the wood waste material, wood waste material discharged when dismantling buildings such as houses, wood waste material discharged when dismantling furniture, wood scraps discharged during building construction, sawdust, etc. are used. . The wood waste material, the waste material resin, the maleic anhydride, and the pigment are contained in the extruded material in an amount of 10 to 60 wt%, 36 to 86 wt%, 2 wt% or less, and 2 wt% or less.

Here, the reason why the wood waste material is included in the extruded material in an amount of 10 to 60 wt% is that if it is less than 10 wt%, it is difficult to give a feeling such as a touch closer to that of real wood. Exceeding this will result in excessive amounts of wood waste, which will reduce the extruded material's formability. In addition, the reason why the waste resin is included in the extruded material in the range of 36 to 86 wt% is that it is difficult to improve the recycle rate of the waste material if it is less than 36 wt%, and it is difficult to melt the waste resin if it exceeds 86 wt%. This is because the extruded material contains a large amount and the moldability of the extruded material decreases. The reason why maleic anhydride and the pigment are contained in an amount of 2 wt% or less based on the whole extruded material is to prevent the moldability of the extruded material from being deteriorated.

Hereinafter, a method of manufacturing the extruded material according to the first embodiment of the present invention will be described with reference to FIG. First, in the pulverizing step, the woody waste material is pulverized to form a woody waste material pulverized powder. This pulverization step is formed by three stages of primary pulverization, secondary pulverization and tertiary pulverization. Needless to say, this pulverization mode is divided into each stage in order to efficiently perform the pulverization, and is not particularly limited to this. The pulverization can be performed by one kind of pulverization process.

The pulverizing apparatus used in the primary pulverizing step has a pulverizing function capable of forming one lump into a large lump having a size of about several centimeters. This is a pulverizing device in which a large number of protrusions are formed on the surface of two opposing rollers, and the rollers passing through the rollers are crushed by rotating the rollers while applying pressure between the rollers. Of course, the crushing device is not limited to this, and other crushing devices for coarse crushing may be used as long as they have the same function. For example, a jaw crusher in which the raw material is put between a jaw opened in an upward V-shape and a vibrating jaw and crushes the raw material by applying pressure, and a movable crushing surface that rotates inside a fixed crushing surface and crushes continuously Other coarse crushers such as a gyre crusher may be used.

Next, in the secondary grinding step, the primary ground material after the primary grinding step is ground into a fine powder. The crusher used in this secondary crushing process is capable of crushing a large lump into a fine powder down to several millimeters or less. The hammer mill uses a hammer mill that crushes and repeats the crushing action until it passes through a round hole in the screen on the outer periphery of the hammer chip. Of course, the crushing device to be used is not limited to the above-mentioned hammer mill, and any other crushing device having the same function may be used. For example, a cutter mill that shreds with a cutter or a roll mill that crushes with a roller may be used.

Next, in the tertiary pulverizing step, the secondary pulverized material after the secondary pulverizing step is pulverized into a fine powder. The crushing device used in the tertiary crushing step is capable of crushing the material obtained in the second crushing step into finer powder. Specifically, it is a so-called pin mill, which can perform fine pulverization by receiving an interaction of impact and repulsion by a pin attached to a disk.

More specifically, the pin mill includes a disk-shaped rotating disk having a large number of pins in a vertical direction, and a fixed disk having a large number of pins on a surface facing the rotating disk. When the material obtained by the pulverization process is introduced into the center of the rotating disk, it enters into the gap between the rotating disk and the pin attached to the fixed disk due to centrifugal force. It can be crushed. In the tertiary pulverization step, the particles are pulverized into particles having a size of about 60 μm by the above-mentioned pin mill. Of course, the crushing device is not limited to the above-described pin mill, but may be another fine crushing device having the same function, for example, a ball mill or a stone mill. In the pulverization process as described above, the collected wood waste is divided into three stages, and the pulverization is performed efficiently step by step.

Next, the waste resin, which is a polypropylene packaging member, is pulverized using, for example, a hammer mill to obtain a pulverized waste resin resin. Then, in the kneading step, the woody waste pulverized wood obtained in the pulverization step, the pulverized waste resin, maleic anhydride, and the pigment are mixed so as to be uniformly distributed. It is put into a hopper, melted in a heating cylinder, and extruded to produce an extruded material. The molding temperature is set at 180 to 220 ° C., and molding is performed at this molding temperature. The reason why the molding temperature was set to 180 to 220 ° C is that if the temperature is lower than 180 ° C, the softened waste resin powder is insufficient and it is difficult to uniformly knead with the woody waste powder. This is because the powder causes a change such as carbonization by heat.

Further, the melt index of the waste resin is set to 3 g / 10 min or less. The melt index as used herein refers to the number of grams of resin extruded per 10 minutes measured under a load of 1.0 kg at 180 ° C. Here, if the melt index exceeds 3 g / 10 min, the fluidity of the waste material resin becomes high, and when the mixed material comprising the waste material resin, the pulverized wood waste material, maleic anhydride, and the pigment is extruded by a screw of an extrusion molding machine. In addition, even if the screw is rotated, friction between the mixed material and the screw hardly occurs, so that the screw is difficult to extrude the mixed material and has poor moldability.

Then, in a molding step, the extruded material is molded into a required shape by applying a predetermined temperature and pressure by an extrusion molding machine or an injection molding machine to produce a wood-like molded product.

According to the first embodiment of the present invention, the crushed waste resin, the crushed wood waste powder, maleic anhydride, and the pigment are mixed to form a mixed material, and the mixed material is melted and formed. Therefore, a molded product in which each pulverized powder is uniformly mixed is obtained. Therefore, since an extruded material is manufactured in this way, and is melted and formed into a required shape, a wood-like molded product used as a building material for a house can be easily obtained. In addition, since the waste resin and the wood waste are reused, they are excellent from the viewpoint of effective use of resources and environmental protection.

Since the mixed material is formed by melting at 180 to 200 ° C., the pulverized waste resin can be sufficiently melted and softened to be evenly mixed with the pulverized wood waste. Moldability at the time of molding can be improved. Since the melt index of the waste material resin is 3 g / 10 min or less, a mixed material having an appropriate fluidity can be obtained by mixing and melting the waste material resin and the pulverized wood waste material powder. Accordingly, the mixed material is easily extruded by the screw, and the moldability is improved.

In addition, the wood waste material and the waste resin are contained in the above-described amount in the entire extruded material, and the wood waste material can be contained in a large amount, so that the feel and texture closer to real wood can be obtained. Can be issued. In addition, the amount of waste material used increases, and the reuse rate of waste material can be improved.

Next, a second embodiment of the present invention will be described. The extruded material according to the second embodiment of the present invention is obtained by mixing and mixing pulverized waste resin obtained by pulverizing waste resin with pulverized wood waste obtained by pulverizing wood waste.

That is, the waste material resin is a waste material mixed resin obtained by mixing a thermoplastic resin, a thermosetting resin, and an impurity, and the extruded material is obtained by roughly pulverizing the waste material mixed resin to 20 mm or less. A coarsely pulverized product is obtained by mixing the coarsely pulverized waste material mixed resin, the pulverized thermoplastic resin, and the pulverized wood waste material powder to form a mixed material, melting the mixed material and molding.

As the waste material mixed resin, for example, plastic garbage by a container packaging recycling method is used. This plastic trash is a first resin containing at least one of acrylic resin containing aluminum hydroxide such as plastic bottles and artificial marble, reinforced plastic (FRP) reinforced with glass fiber, and nylon. In addition, the first resin may include paper, cloth, and aluminum foil.

[0093] Examples of the thermosetting resin include a phenol resin, a melamine resin, a urethane resin, and a polyurethane resin. The thermoplastic resin is, for example, a second resin obtained from a container or a package of food, including a beverage, a tray, or the like. The second resin contains at least one of a polypropylene resin (PP), a polyvinyl chloride resin (PVC), a polyethylene resin (PE), a vinyl chloride resin, and a polystyrene resin. .

[0094] The woody waste materials include woody waste materials that are discharged when a building such as a house is dismantled, woody waste materials that are discharged when a piece of furniture is dismantled, wood offcuts that are discharged during building construction, sawdust and the like. Use The wood waste material and the waste resin are contained in the extruded material in an amount of 10 to 60 wt% and 36 to 86 wt%, respectively.

Hereinafter, a method for manufacturing the extruded material according to the second embodiment of the present invention will be described with reference to FIG. First, the woody waste material is pulverized by the above-mentioned pulverization step to obtain a pulverized woody waste material. Then, the waste material mixed resin obtained by mixing the thermoplastic resin, the thermosetting resin, and the impurities is pulverized. That is, the waste material mixed resin is roughly pulverized to, for example, 20 mm or less using a hammer mill to obtain a roughly pulverized waste material mixed resin. Further, the above-mentioned polypropylene packaging member is pulverized using, for example, a hammer mill to obtain pulverized thermoplastic resin powder.

Next, in the kneading step, the woody waste pulverized powder obtained in the pulverization step, the coarsely pulverized waste material mixed resin pulverized to 20 mm or less, and the pulverized thermoplastic resin are uniformly distributed. The mixed material is put into a hopper of an extruder, melted in a heating cylinder, and extruded to produce an extruded material. The molding temperature is set at 180 to 220 ° C., and the melt index of the waste resin is 3 g / min or less. After that, the extruded material is melted in a molding step and molded into a required shape by an extruder or an injection molding machine to produce a wood-like molded product.

According to the second embodiment of the present invention, the same effect as that of the first embodiment can be obtained, and of course, the waste material mixed resin is roughly pulverized to 20 mm or less. The crushed thermoplastic resin is mixed with the crushed wood waste material powder to form a mixed material, and the mixed material is melted and molded. Therefore, the crushed waste resin mixed resin, thermoplastic resin, and crushed wood waste material powder are used. Is a uniformly mixed molded product.

[0098] Therefore, an extruded material is manufactured from a waste resin mixed resin obtained by mixing a thermoplastic resin which is easy to melt, a thermosetting resin which is hard to melt, and impurities, and a wood waste material, and the extruded material is melted to obtain a required material. By molding into a shape, a wood-like molded product used as a building material for a house can be easily obtained. Further, since the waste material-mixed resin is a mixture of a thermoplastic resin, a thermosetting resin, and an impurity, the waste material is used more and the reuse rate of the waste material is reduced as compared with the first embodiment. Can be improved.

Next, a third embodiment of the present invention will be described. The extruded material according to the third embodiment of the present invention is obtained by mixing a crushed waste resin material obtained by crushing waste resin with a crushed wood waste material powder obtained by crushing wood waste material. The mixed material is formed by melting and mixing the mixed material. That is, the waste material resin is a waste material mixed resin obtained by mixing a thermoplastic resin, a thermosetting resin, and an impurity, and the extruded material is obtained by roughly pulverizing the waste material mixed resin to 20 mm or less. The coarsely pulverized waste material-mixed resin is fused and solidified to form a solidified waste material-mixed resin, and the solidified waste material-mixed resin is pulverized into a solidified pulverized powder. And the pulverized thermoplastic resin and the pulverized wood waste material are mixed to form a mixed material, and the mixed material is melted and formed. The wood waste material and the waste resin are contained in the extruded material in an amount of 10 to 60 wt% and 36 to 86 wt%, respectively.

The waste material mixed resin, the thermosetting resin, the thermoplastic resin, and the wood waste material are the same as those in the second embodiment of the present invention, and a description thereof will be omitted. Hereinafter, a manufacturing method for manufacturing the extruded material according to the third embodiment of the present invention will be described with reference to FIG.

First, the wood waste material is pulverized in the above-described pulverizing step to obtain a pulverized wood waste material. Then, the waste material mixed resin is roughly pulverized to, for example, 20 mm or less using a hammer mill to obtain a roughly pulverized waste material mixed resin, and the waste material mixed resin coarsely pulverized by using an extruder under high pressure to generate heat. To solidify and solidify the waste material mixed resin. Further, the solidified waste resin-mixed resin is pulverized into a solidified pulverized powder. Further, the above-mentioned polypropylene packaging member is pulverized using, for example, a hammer mill to obtain a pulverized thermoplastic resin powder.

Next, in a kneading step, the solidified pulverized powder, the pulverized thermoplastic resin, and the wood pulverized wood pulverized powder are mixed so as to be uniformly distributed, and the mixed material is placed in a hopper of an extruder. The extruded material is manufactured by charging, melting and extruding in a heating cylinder.

The molding temperature is set at 180 to 220 ° C., and the melt index of the waste resin is 3 g / min or less. After that, the extruded material is melted in a molding step and molded into a required shape by an extruder or an injection molding machine to produce a wood-like molded product.

According to the third embodiment of the present invention, it is possible to obtain the same effect as that of the first embodiment. , Fused and solidified, further pulverized, and then mixed with the pulverized thermoplastic resin and the pulverized wood waste material to form a mixed material, and the mixed material is melted and molded to obtain a solidified material. Each of the pulverized powder, the thermoplastic resin, and the pulverized wood waste powder is a uniformly mixed product.

Therefore, an extruded material is manufactured from a waste resin mixed resin obtained by mixing a thermoplastic resin which is easily melted, a thermosetting resin which is hardly melted, and impurities, and a woody waste material. By molding into a shape, a wood-like molded product used as a building material for a house can be easily obtained.

Further, since the waste material mixed resin is formed into a pulverized powder of solidified material, mixed and melted and molded, compared with the second embodiment, the thermosetting resin, impurities, heat The plastic resin can be uniformly mixed without being separated, and the moldability is improved. Furthermore, since the waste material-mixed resin contains a mixture of a thermoplastic resin, a thermosetting resin, and impurities, the waste material is used more and the reuse rate of the waste material is reduced as compared with the first embodiment. Can be improved.

Next, a fourth embodiment of the present invention will be described. The extruded material of the present invention is a mixed material obtained by mixing crushed wood waste material obtained by crushing wood waste material, crushed powder of waste material resin obtained from waste material containing impurities, and weak anion exchange resin. The mixed material is melted and molded. That is, the recovered agricultural vinyl is used for the waste resin containing the impurities. The agricultural vinyl is, for example, a polyvinyl chloride sheet for a vinyl house, to which a nitrogen fertilizer containing nitrate ions is attached. Examples of the weak anion exchange resin include a resin having a diethylaminoethyl group bonded thereto.

[0108] Further, the wood waste material pulverized powder, the waste material resin pulverized powder, and the weak anion exchange resin are contained in the extruded material in an amount of 30 to 60 wt%, 20 to 69 wt%, and 1 to 20 wt%, respectively.

Here, the reason why the wood waste material pulverized powder is included in the extruded material in an amount of 30 to 60 wt% is that if it is less than 30 wt%, it is difficult to give a feeling such as a touch closer to real wood, %, The amount of wood becomes excessive and the formability of the extruded material decreases. The reason why the waste resin pulverized powder is contained in the extruded material in an amount of 20 to 69 wt% is that if it is less than 20 wt%, the recycle rate of the waste material cannot be improved. This is because impurities that are difficult to melt in the powder are increased, and the extruded material has poor moldability. Furthermore, the reason that the weak anion exchange resin is contained in an amount of 1 to 20 wt% with respect to the whole extruded material is that if it is less than 1 wt%, the amount of the weak anion exchange resin is too small, so that the function as an ion exchange resin is sufficiently performed. If the content exceeds 20 wt%, a large amount of weak anion exchange resin is contained, so that a wood-like molded article having a woody feel cannot be obtained.

Since the wood waste is the same as that of the first embodiment of the present invention, the description is omitted. Hereinafter, a method of manufacturing the extruded material according to the fourth embodiment of the present invention will be described. First, the woody waste material is pulverized by the above-mentioned pulverization step to obtain a pulverized woody waste material. Then, the collected agricultural vinyl is crushed using, for example, a hammer mill to obtain a crushed waste resin powder. On the other hand, the weak anion exchange resin is similarly ground using a hammer mill.

Then, the pulverized wood waste material, the pulverized waste resin powder, and the weak anion exchange resin obtained as described above are kneaded so as to be uniformly distributed. Then, the kneaded wood waste material powder, the waste material resin powder and the weak anion exchange resin are put into a hopper of an extruder, melted in a heating cylinder and extruded to produce an extruded material. Here, for example, the kneaded mixture may be extruded in a string form from a perforated circular nozzle and cut into a pellet-shaped extruded material. By making the shape like a pellet, it is difficult to absorb moisture during transportation and storage, and it is easy to maintain the same quality, which is convenient.

The extruded material is usually made into a wood-like molded product by the following steps, and an example of this step will be described below. First, the extruded material is molded into a required shape by an extruder or an injection molding machine by applying a predetermined temperature and pressure.

In this molding step, the molding temperature is set at 160 to 220 ° C., and molding is performed at this molding temperature. Here, the molding temperature in the molding step was set to 160 to 220 ° C. If the temperature is lower than 160 ° C, the softening of the waste resin pulverized powder and the weak anion exchange resin is insufficient and it is difficult to uniformly knead the woody waste pulverized powder. At 220 ° C. or higher, the pulverized woody waste material causes a change such as carbonization due to heat. Since the molding temperature is set at 160 to 220 ° C. in this manner, the waste wood pulverized powder obtained in the pulverizing step is not changed by heat in the molding step, and the waste resin pulverized powder and the weak anion exchange resin are sufficiently removed. It can be melted and softened and evenly kneaded with the pulverized wood waste material, whereby a wood-like molded product can be obtained easily and reliably.

According to the embodiment of the present invention, it is possible to obtain the same effects as those of the first embodiment, as well as the pulverized wood waste material obtained from the wood waste material and the collected powder. A mixture of crushed powder of waste resin obtained from agricultural vinyl and a weak anion exchange resin is mixed to form a mixed material, and this mixed material is melted and molded. The anions in the anion exchange resin are ionized and undergo ion exchange reaction with nitrate ions contained in the nitrogen fertilizer attached to agricultural vinyl. Therefore, nitrate ions that generate odor can be removed, and a deodorizing effect can be obtained. Furthermore, by melting and molding such an extruded material to produce a wood-like molded product, it can be used as a building material for a house.

[0115] Further, since the woody waste material and the collected agricultural vinyl are reused, the reuse rate can be improved. Furthermore, the use of agricultural vinyl, which has a low unit price, leads to cost reduction. Further, as described above, the extruded material that is easily deodorized can be manufactured by mixing and melting the weak anion exchange resin in the pulverized wood waste material and the pulverized waste resin resin, and extruding the mixture. .

In order to obtain a more deodorizing effect, for example, molecular sieve, zeolite, expanded shirasu earth, activated carbon, etc. are kneaded and melted together with cellulose-based fine particles, waste resin ground powder, and weak anion exchange resin. It is good to solidify. In this case, the molecular sieve, zeolite, expanded shirasu soil, activated carbon, etc. are adjusted so that each contains 1 to 10% by weight.

The mixing of the wood waste material, the waste material resin, and the weak anion exchange resin may be performed before the pulverization. That is, uncrushed wood waste material, a waste material resin and a weak anion exchange resin are mixed, and in the same manner as described above, the wood waste material becomes a wood waste material ground powder, and the waste material resin and the weak anion exchange resin Grind until the resin becomes powdery. Then, the pulverized mixed material is kneaded, melted, and extruded to produce an extruded material.
