[Problems to be solved by the invention]

 By the way, in the above-mentioned Japanese Patent Application Laid-Open No. 10-272695, in the coloring process, after a paint is applied to the uneven surface of the wooden-like molded product, only the wiping groove is colored before drying. In the painting process, a color sanding sealer is applied to the colored surface. Here, the paint (undercoat) applied only to the groove portion was usually a brown wood color similar to the topcoat paint applied to the upper surface, that is, the color sanding sealer. Therefore, the color of the undercoating paint was concealed by the brown woody topcoating paint and was not visible from the surface of the wood-like molded article.

[0004] As a coating method for coating the surface of a wood-like molded product, for example, a primer (undercoat paint) is applied to the uneven surface of the wood-like molded product, and further, a brownish paint is applied to the upper surface of the primer. A method of applying a wood-colored top-coating paint may be used. Also in this case, usually, the primer had a brown wood color similar to that of the top coat or a transparent color, so that the color of the primer was hidden by the top coat. Therefore, it is desired to further improve the texture by reflecting the color of the undercoat paint directly applied to the surface of the wood-like molded article on the color of the overcoat paint.

The present invention has been made in view of the above circumstances, and reflects the color of a primer (undercoat paint) applied to the surface to the color of a topcoat paint applied to the upper surface of the primer. Accordingly, an object of the present invention is to provide a resin molded product and a resin molded product manufacturing apparatus capable of improving the texture.

Here, the reason why the particle size of the cellulose-based fine particles 3 is set to 1 to 300 μm is that when the particle size is larger than 300 μm, uniform mixing and melting with the resin 5 occur. It is because it is difficult to knead. On the other hand, if the particle size is smaller than 1 micron, the cellulose-based fine powder particles 3 become too small, and it is difficult to give a woody feeling to the molded resin molded product 1, and it is also difficult to grind the resin molded product 1. .

According to the invention of claim 13, for example, as shown in FIG. 1, in the resin molded article 1 according to any one of claims 1 to 12, the resin 5 is obtained from a resin waste material 4 containing impurities. It is characterized by the following.

According to the invention of claim 13, it is possible to obtain the same effect as any one of claims 1 to 12, and also to use the resin waste material 4 to make effective use of resources and Excellent from the viewpoint of environmental protection.

Examples of the resin waste material 4 include containers and packaging of foods including beverages, trays, and the like. These resin waste materials 4 include polypropylene resin, polyvinyl chloride resin, polyethylene resin, and polyvinyl chloride foam. Resin 5 such as resin, polystyrene resin and ABS resin is obtained.

According to the invention of claim 14, as shown in FIG. 1, for example, in the resin molded product 1 according to any one of claims 1 to 13, the resin 5 has a particle diameter of 1 to 300 μm. It is characterized by the following.

According to the invention of claim 14, the same effect as any of claims 1 to 13 can be obtained, and the cellulose contained in the resin 5 and the material 7 can be obtained. When kneading and melting with the system fine powder particles 3, they can be uniformly kneaded, and the moldability is improved. For example, even if the resin 5 is a polyvinyl chloride resin or the like, the resin 5 is uniformly mixed with the cellulosic fine particles 3 without being decomposed by thermal decomposition before kneading and melting. State. Further, when kneading and melting, even if additives such as inorganic pigments and reinforcing agents are added, the dispersion can be performed well, and therefore, the cellulose-based fine particles 3, the resin 5, and the additives can be uniformly mixed. Can be mixed.

Here, the reason why the particle size of the resin 5 is set to 1 to 300 μm is that when the particle size is larger than 300 μm, the cellulose-based fine powder particles 3 contained in the material 7 are different from each other. This is because when kneading and melting, it is difficult to uniformly mix with the cellulosic fine powder particles 3. On the other hand, if the particle size is smaller than 1 micrometer, the pulverizing operation becomes difficult.

The invention of claim 15 is, for example, as shown in FIG. 1, in the resin molded product 1 according to any one of claims 10 to 12, It is characterized in that the grains 3 contain 10 to 60 wt% and the resin contains 36 to 86 wt%, respectively.

Therefore, the material 7 can be easily pulverized by the pulverizing means (for example, the wood pulverizing means 13 and the resin pulverizing means 15) (claim 22) after the separating means 12. Further, when the material 7 containing no metals is used as the resin molded article 1 by the molding means 11, the moldability is improved.

The invention of claim 21 is, for example, as shown in FIG. 1, in the resin molded article manufacturing apparatus 6 according to claim 20, wherein the sorting means 12 is provided with a first sorting means 12a for sorting and removing metals. A second sorting means 12b for sorting and removing stainless steel; and a third sorting means 12c for sorting and removing metal which is conductive but does not adhere to a magnet.

According to the invention of claim 21, it is possible to obtain the same effect as in claim 20, of course, the first sorting means 12 a, the second sorting means 12 b, and the third sorting means. Since the material 12c is provided, impurities can be more reliably removed from the material 7, and the formability of the forming means 11 can be improved.

Here, the resin molded product 1 is manufactured by the following resin molded product manufacturing apparatus 6. As shown in FIG. 1, the resin molded product manufacturing apparatus 6 includes a kneading means 8 for kneading and melting the cellulosic fine particles 3 and the resin 5 to form a mixed material 7, and cooling and stirring the mixed material 7. Then, cooling and stirring means 10 for converting the powdered solidified material 9 into a required shape is formed on the surface 31 of the resin molded article 1 formed by the molding means 11. A coating means (not shown) for applying a black to gray primer 34 and applying a brown wood paint 35 on the upper surface of the primer 34 is provided. Further, before the kneading means 8, a separating means 12 for removing metals from the woody waste material 2, and the woody waste material 2 from which the metals have been removed by the separating means 12 are finely pulverized so that the cellulose-based fine particles 3 can be formed. There are provided a wood crushing means 13 for obtaining wood and a resin crushing means 15 for obtaining resin 5 by finely crushing the resin waste material 2.

The wood crushing means 13 includes a primary wood crushing means 13a, a secondary wood crushing means 13b, and a tertiary wood crushing means 13c. Then, as shown in FIG. 1, when the wood waste material 2 and the resin waste material 4 are transported to the molding plant, the wood waste material 2 having a size of about 4 to 5 cm is reduced by several millimeters by the primary wood grinding means 13a. (Primary wood crushing step A).

The primary wood crushing means 13a has a crushing function capable of forming a large lump having a size of about several millimeters. Specifically, two primary crushing means 13a are used. This is a pulverizing device that forms a large number of protrusions on the surface of an opposing roller and rotates the roller while applying pressure between the rollers, thereby crushing what passes between them. Of course, the primary wood crushing means 13a is not limited to this, and another crushing device for coarse crushing may be used as long as it has 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.

Thereafter, the pulverized wood waste material 2 is dried by a hot air generator (hot air generating means) 22 while being sent by hot air and sent to a tank 27. Then, the wood waste 2 stored in the tank 27 is removed of metals by the sorting means 12. The separating means 12 includes a iron removing machine (a first separating means) 12a such as a strong magnet that sorts and removes a metal, a stainless steel sorting machine (a second sorting means) 12b that sorts and removes stainless steel, and a conductive material. A non-ferrous sorter (third sorter) 12c for sorting and removing metals that are not attached to the magnet (sorting step B). Then, impurities are reliably removed by the first to third sorting means 12a, 12b, 12c.

The wood waste material 2 separated by the separating means 12 is pulverized into fine powder by the secondary wood pulverizing means 13b (secondary wood pulverizing step C). The secondary wood crushing means 13b is capable of crushing large blocks into fine powders to about 1 mm. Specifically, the secondary wood crushing means 13b crushes the material with a high-speed rotating hammer chip, It uses a hammer mill that repeats the crushing action until it passes through a round hole in the screen on the outer periphery of the chip. Of course, the secondary wood crushing means 13b to be used is not limited to the above-mentioned hammer mill, but may be any other crusher having the same function. For example, a cutter mill that shreds with a cutter or a roll mill that crushes with a roller may be used.

The secondary wood crushed material (woody waste material 2) crushed by the secondary wood crushing means 13 b in this manner is again dried while being sent by hot air by the hot air generator (hot air generating means) 22, and the tank 27 is dried. Sent to Next, the secondary wood crushed material 2 stored in the tank 27 is crushed into fine powder by the tertiary wood crushing means 13c to obtain the cellulose-based fine particles 3 (tertiary wood crushing step D). The tertiary wood crushing means 13c is capable of crushing the material 2 obtained by the secondary wood crushing means 13b into a 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 13b is injected into the center of the rotating disk, it enters the gap between the rotating disk and the pin attached to the fixed disk by centrifugal force, and is pulverized into fine powder by the interaction of impact and repulsion by the pin. It is something that can be done. In the tertiary wood crushing step D, the crushed wood is crushed into particles having a size of about 300 μm by the above-mentioned pin mill. Of course, the tertiary wood crushing means 13c 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. By the wood crushing means 13 as described above, the collected wood waste material 2 is divided into three stages, and the crushing is efficiently performed stepwise.

The cellulosic fine powder particles 3 finely pulverized by the tertiary wood pulverizing means 13c in this manner are dried by hot air generated by the hot air generator (hot air generating means) 22 again and sent to the tank 27. The cellulosic fine particles 3 are sieved through a sieve 26 and sorted to an average particle size of 300 microns. If the cellulosic fine powder particles 3 have a particle diameter of 300 μm or more, they are crushed again by wood crushing means. This wood re-grinding means is the tertiary wood crushing means 13c. The cellulose fine powder 3 having a particle size of 1 to 300 μm is dried by a hot air generator (hot air generating means) 22 while being sent by hot air, sent to a tank 27, and then stored in a wood powder storage tank 23. Is done.

On the other hand, the resin waste material 4 is converted into a resin 5 having an average particle diameter of 300 μm by the resin crushing means 15 (resin crushing step H). That is, the resin pulverizing means 15 includes a primary resin pulverizing means, a secondary resin pulverizing means, and a tertiary resin pulverizing means. 13b and the same as the tertiary wood crushing means 13c, the description thereof will be omitted.

The resin 5 finely pulverized by the resin pulverizing means 15 in this manner is also sieved (not shown) to select an average particle diameter of 300 μm. Then, those having a particle size of 300 μm or more are crushed again by the resin crushing means. This resin re-grinding means is the tertiary resin crushing means. The resin 5 having a particle size of 1 to 300 μm is dried by a hot air generator (hot air generating means) 22 while being sent by hot air, sent to a tank 27, and then stored in a resin storage tank 24. .

Next, the cellulosic fine particles 3 stored in the wood flour storage tank 23 and the resin 5 stored in the resin storage tank 24 are pre-oiled through the wood flour / resin charging unit 25. It is put into a mixing mixer (kneading means) 8 heated by a temperature controller, and is heated by self-heating (frictional heat) to be stirred at about 175 ° C to 185 ° C. At this time, the inorganic pigment is introduced into the mixing mixer 8 from the inorganic pigment introducing section 16 and the reinforcing agent is introduced into the mixing mixer 8 from the reinforcing agent introducing section 17, whereby the inorganic pigment is surrounded around the cellulose-based fine particles 3. I'm irritated. The reinforcing agent is added to improve the adhesion between the resin 5 and the cellulose-based fine particles 3.

The mixing mixer 8 stirs the cellulose-based fine particles 3 and the resin 5 at a high rotation speed and, after reaching a melting temperature at which the resin 5 melts, stirs at a low rotation speed and kneads at a low speed. -It becomes the mixed material 7 by melting (kneading process E). Here, the cellulosic fine particles 3 and the resin 5 are adjusted so as to contain 10 to 60% by weight and the resin 5 to 36 to 86% by weight, respectively, based on the entire resin molded article 1, and the inorganic pigment and the reinforcing agent are combined. 100 wt%. By including the cellulose-based fine particles 3 in an amount of 10 to 60 wt% and the resin 5 in an amount of 36 to 86 wt%, it is possible to include the cellulose-based fine particles 3 in a large amount. Can be issued. In addition, the resin 5 and the cellulosic fine powder 3 can be uniformly mixed, and the moldability is improved.

The mixed material 7 kneaded and melted by the mixing mixer 8 is put into a cooling mixer (cooling and stirring means) 10 and stirred at a low speed until cooled to 80 ° C. The cooled mixed material 7 becomes a powdered solidified material 9 (cooling and stirring step F).

As shown in FIG. 2, the cooling mixer 10 includes a mixing tank 18, a first stirring blade 19 provided on a bottom surface of the mixing tank 18, and rotating around a vertical axis. Two stirring blades 20 provided on the inner peripheral surface of the mixing tank 18 and rotating about a horizontal axis; and the second stirring blade 20 provided on the outer peripheral surface of the mixing tank 18 at the position of the second stirring blade 20. And a motor 21 for driving the motor. Although not shown, a cooling device for cooling the inside of the mixing tank 18 and a motor for driving the first stirring blade 19 are also provided.

The first stirring blade 19 includes four blades, and is configured to stir the charged material around a vertical axis. The second stirring blade 20 is provided with a plurality of fine blades, and is configured to further finely stir the material stirred by the first stirring blade 19 around the horizontal axis. When the mixed material 7 is charged into such a cooling mixer 10, the charged material 7 is stirred by the first stirring blade 19 and the second stirring blade 20 to form the solidified powder 9. . This solidified material 9 is stored in the tank 27.

Then, the solidified material 9 stored in the tank 27 is put into a hopper of an extruder (forming means) 11 and melted in a heating cylinder. Thereafter, the solidified material 9 is extruded by a screw inside the extruder 11, and is extruded from a mold 29 to be formed into a required shape (forming step G).

The molding temperature is set at 180 ° C. to 220 ° C., and molding is performed at this molding temperature. Here, the reason why the molding temperature was set to 180 to 220 ° C. is that if the temperature is lower than 180 ° C., the softening of the resin 5 is insufficient and it is difficult to uniformly knead with the cellulosic fine particles 3. No. 3 causes changes such as carbonization by heat. Further, the mold 29 from which the solidified material 9 is extruded has its front end heated and its base end cooled. By extruding the solidified material 9 by such a mold 29, the solidified material 29 extruded by the base-side mold 29 is used as the resin molded article 1.

Next, although not shown, the concaves and convexes 32 are provided on the surface 31 of the resin molded article 1 by forming a large number of grooves 33 at predetermined intervals by embossing means (embossing step). . In other words, this embossing means is an embossing device provided with a rotating shaft and a cylindrical embossing roller rotatable around the axis of the rotating shaft, and the peripheral surface of the embossing roller has an equal width and a high height. Many protrusions having different sizes are provided. Then, the emboss roller is rotated and rubbed against the resin molded product 1 while being pressed from above. Then, the surface 31 of the resin molded article 1 is cut into a groove shape by the projection, whereby a large number of groove portions 33 having the same width and different depth are formed on the surface 31.

[0097] The width of the resin molded article 1 is reduced while being pressed against the surface 31 of the resin molded product 1 by using an embossed roller having low projections and an embossing roller having high projections in two steps. A plurality of grooves 33 having the same depth and different depths may be formed. The depth of the groove 33 may be three or more. In this case, a plurality of types of emboss rollers having different projection heights are used.

Further, a number of irregularities 32 are formed by rubbing the surface 31 of the resin molded article 1 with a hairline processing means (hairline processing step). The hairline processing means is, for example, sanding paper.

Thereafter, a black to gray primer 34 is applied to the surface 31 of the resin molded article 1 having the irregularities 32 by a coating means, and the surface 31 of the resin molded article 1 to which the primer 34 has been applied is dried. Next, a brown wood paint 35 is applied to the upper surface of the primer 34. The primer 34 is an undercoating paint for bringing a brown wood paint 35 into close contact with the surface 31 of the resin molded article 1 or for enhancing rust resistance. In this case, a black to gray pigment is mixed. Use chlorinated polypropylene resin paint. As the brown wood color paint 35, a paint containing urethane resin, acrylic silicone resin or the like is used.
