Description

  The present invention relates to a resin molded body having a wood texture.

  Conventionally, various research and development have been conducted on a resin molded body made of a thermoplastic resin material having a woodgrain pattern. For example, Patent Document 1 discloses a method for producing a resin molded body provided with a woodgrain pattern without being scratched and without sacrificing strength.

  The resin molded body described in Patent Document 1 has a resin layer having a surface exhibiting a woodgrain pattern, and the resin layer includes a first thermoplastic resin and a first melting point higher than that of the first thermoplastic resin. 2 is made of a mixed material containing two thermoplastic resins in an incompatible state, and the pattern is formed by color spots of the incompatible first and second thermoplastic resins. It has a woodgrain pattern.

Japanese Patent No. 4388686

  According to the invention described in Patent Document 1, at least the outermost layer is formed using a resin material containing two or more thermoplastic resins having different melting points, and the thermoplastic resin having a high melting point is made into a molten state or a semi-molten state and stretched. As a result, a variety of wood grain patterns can be formed without forming large scratches or weld lines on the surface of the resin molded body, and the wood grain has excellent durability and productivity. A resin molded body having a toned pattern can be obtained.

However, in general, a resin molded body having a wood texture is often used in an outdoor environment and is often exposed to rain and wind.
Therefore, a symptom called rain stain may occur on the surface of the resin molded body, which is a problem.
Rain stain refers to a phenomenon in which a colored component (derived from wood flour) contained in a resin molded body oozes out on the surface of the resin molded body when the resin molded body is exposed to rain and wind.

An object of the present invention is to provide a resin molded article having a wood texture that does not make rain stains conspicuous.
Another object of the present invention is to provide a resin molded article having a wood texture that does not cause rain stains.

(1)
The resin molded body having a wood texture according to one aspect is a resin molded body including a base layer and a surface layer formed on the surface of the base layer, and the surface layer mainly includes only a thermoplastic resin and an inorganic filler. Is contained, and the surface of the surface layer is subjected to uneven processing.
In addition, the surface layer should just be formed in the upper surface of the resin molding in the state which uses the resin molding of this invention, and may be formed in a side part and / or a back surface part. Furthermore, when a hollow part is formed in the resin molded body for the purpose of reducing the weight, reducing the material used, etc., it may be formed on the surface of the hollow part.
Further, mainly only the thermoplastic resin and the inorganic filler means that it is substantially composed of the thermoplastic resin and the inorganic filler, and the other thing shows a possibility of being slightly contained. For example, the thermoplastic resin may be a reinforcing material such as glass fiber or carbon fiber, a plasticizer, a foaming agent, a flame retardant, an antioxidant, a nucleating agent, a pigment, an ultraviolet absorber, an ultraviolet deterioration preventing agent, if necessary. An antioxidant such as an antioxidant, an additive such as an α, β unsaturated carboxylic acid monomer, an affinity improver such as an acid-modified olefin or an acid-modified low-molecular olefin may be blended.

In this case, the resin molded body to which the wood texture is imparted consists of a base layer and a surface layer. And since the surface layer is made only of resin and inorganic filler, it does not contain organic filler which is the cause of rain stain, so it is possible to reliably prevent the occurrence of rain stain in the resin molded body with wood texture. it can.
In addition, since it is as above-mentioned, the resin molding of this invention is not only the use of the deck material which has the influence of rain water or water spraying, such as an outdoor garden balcony or a roof balcony, but an indoor watering part or dew condensation water etc. It can also be suitably used for a part having an influence of the above.

(2)
The resin molded body to which the wood texture according to the second invention is imparted is the resin molded body to which the wood texture according to one aspect of the invention is imparted, and the surface layer has a surface roughness in the range of 20 μm to 300 μm.

  In this case, since the surface roughness of the surface layer is in the range of 20 μm or more and 300 μm or less, a wood texture can be given to the surface.

(3)
The resin molded body to which the wood texture according to the third invention is applied is the resin molded body to which the wood texture according to one aspect or the second invention is applied, and the content of the inorganic filler is 20 with respect to the thermoplastic resin. It may be not less than 50% by mass and not more than 50% by mass.

  In this case, the content of the inorganic filler is 20% by mass or more and 50% by mass or less with respect to the resin. If it is less than 20% by mass, the wood texture is poor, and if it exceeds 50% by mass, a molding problem occurs and molding cannot be performed.

(4)
According to a fourth aspect of the present invention, there is provided a resin molded body provided with a wood texture according to any one of the third aspects of the present invention, wherein the inorganic filler comprises talc. The average particle size of is 1 μm or more and 1000 μm or less.

  In this case, the inorganic filler is made of talc, and the average particle size of talc is 1 μm or more and 1000 μm or less. Moreover, it is more preferable that they are 5 micrometers or more and 300 micrometers or less. When the average particle size of talc is less than 1 μm, the viscosity increases and it becomes difficult to uniformly disperse in the surface layer. Moreover, when the average particle diameter of talc exceeds 1000 μm, the grains are conspicuous and the appearance becomes rough. Furthermore, if necessary, talc may be surface-treated with a silane coupling agent or a coupling agent.

(5)
According to a fifth aspect of the present invention, there is provided a resin molded body imparted with a wood texture according to any one of the fourth aspect of the present invention, wherein the resin molded body further includes an organic filler. Is contained, and the content of the organic filler is 20% by mass or less based on the resin.

  In this case, the content of the organic filler is 20% by mass or less with respect to the thermoplastic resin. When the content of the organic filler is more than 20% by mass relative to the resin, rain stains become conspicuous, which is not preferable.

(6)
The resin molded body to which the wood texture according to the sixth invention is applied is the resin molded body to which the wood texture according to the fifth invention is applied. In the case where the organic filler is contained, the organic filler is made of wood powder. The average particle size of the wood flour is 50 μm or more and 200 μm or less.

  In this case, the organic filler in the case where the organic filler is contained is made of wood powder, and the average particle diameter of the wood powder is 50 μm or more and 200 μm or less. In this case, a wood texture like natural wood can be sufficiently obtained while suppressing the occurrence of rain stains.

(A)
The concavo-convex processing is formed by processing by one surface of the polishing sheet wound in a substantially triangular shape. In this case, since the unevenness treatment of the resin molded body is performed by processing by one surface of the polishing sheet wound in a substantially triangular shape, the contact time and the contact area can be increased as compared with the circular polishing roller. The mechanical unevenness can be efficiently performed on the layer.

It is a schematic diagram which shows an example of the resin molding which provided the wood texture based on 1st Embodiment. It is a schematic diagram which shows an example of the manufacturing method of the resin molding which provided the wood texture of FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a schematic diagram showing an example of a resin molded body 100 provided with a wood texture according to the first embodiment.

  As shown in FIG. 1, a resin molded body 100 having a wood texture is composed of a base layer 200 and a surface layer 300.

(Base layer)
The base layer 200 is not particularly limited, but is formed from an organic (or inorganic) filler and a thermoplastic resin. The base layer 200 is made of a low-stretch and high-strength material, and coal ash fly ash or the like is preferably used as an inorganic filler, but is not limited thereto, and any other material may be used. .

(Surface layer)
Next, the surface layer 300 is mainly formed only from a thermoplastic resin and an inorganic filler.
Further, the surface layer 300 may substantially contain additives such as pigments, weathering agents, and flame retardants. Further, it is assumed that the surface layer 300 does not contain an organic filler, but the surface layer 300 is not limited to this, and the surface layer 300 contains 20% by mass of the organic filler in addition to the thermoplastic resin and the inorganic filler. It may be added within the following range.

Further, for example, the surface layer 300 preferably has a thickness in the range of 0.1 mm to 20.0 mm, and more preferably in the range of 0.2 mm to 7.0 mm. The reason is that if the thickness is less than 0.2 mm, scratches during decoration during production are likely to affect the base layer, whereas if it is thicker than 7.0 mm, the cooling efficiency during molding is poor and the productivity is low. This is because it deteriorates.
Hereinafter, a thermoplastic resin, an inorganic filler, and an organic filler are demonstrated.

(Thermoplastic resin)
The thermoplastic resin used for the surface layer 300 is, for example, polyethylene, polypropylene, polyamide, polyacetal, polyethylene terephthalate, polybutylene terephthalate, fluorine resin, polyphenylene sulfide, polystyrene, ABS resin, acrylic resin, polycarbonate, polyurethane, vinyl chloride. , Polyphenylene oxide, ethylene vinyl acetate copolymer and the like.

  In view of cost, it is preferable to use an olefin resin (polyolefin) such as polyethylene or polypropylene. Furthermore, the above-mentioned thermoplastic resins are not limited to one type, and two or more types may be mixed.

  As an example of the multi-mixing, for example, an appropriate thermoplastic resin such as an acrylic resin or a saturated polyester resin can be used. In particular, those having a low compatibility with other thermoplastic resins and a higher melting point and viscosity than other thermoplastic resins can be suitably used.

  Furthermore, in addition to the above resins, the thermoplastic resin may be a reinforcing material such as glass fiber or carbon fiber, a plasticizer, a foaming agent, a flame retardant, an antioxidant, a nucleating agent, a pigment, a UV absorber, Additives such as UV degradation inhibitors, oxidation degradation inhibitors, α, β unsaturated carboxylic acid monomers, and affinity improvers such as acid-modified olefins and acid-modified low-molecular olefins may be blended.

(Inorganic filler)
Examples of the inorganic filler used for the surface layer 300 include talc, kaolin, calcium carbonate, silica, magnesium hydroxide, mica, fly ash, calcium silicate, mica, molybdenum dioxide, talc, glass fiber, glass beads, and oxidation. titanium, asbestos, magnesium oxide, barium sulfate, clay, dolomite, calcium, aluminate hydrate, metal powders such as iron powder, aluminum hydroxide, ettringite, silica sand, borax, and alumina or the like. These fillers may be used alone or in combination of two or more.

  Further, as the inorganic filler, a plate-like inorganic filler is preferable in order to give a wooden texture. Further, a material having a low hardness that is less affected by wear damage to the apparatus during production is preferable. For example, it is more preferable to use talc, mica or the like.

  The filling amount of the inorganic filler is preferably in the range of 20% by mass or more and 50% by mass or less. If the inorganic filler is less than 20% by mass, the wood texture is poor, and if it exceeds 50% by mass, the wood texture is obtained, but kneading becomes insufficient, and the molding does not disperse uniformly due to the relationship with the thermoplastic resin. The problem arises above. Moreover, there is a risk of insufficiency in strength.

Moreover, the average particle diameter of an inorganic filler can use the thing of the range of 1 micrometer or more and 1000 micrometers or less. Furthermore, it is preferable to use a thing of 5 micrometers or more and 300 micrometers or less. The reason is that when the thickness is less than 5 μm, it becomes difficult to uniformly disperse the inorganic filler in the thermoplastic resin, and the material viscosity in the extruder during production increases and the extrusion moldability decreases. is there.
On the other hand, if it exceeds 300 μm, the grains are conspicuous and the appearance becomes rough, and the surface property of the molded product is lowered. In addition, you may surface-treat a filler with a silane coupling agent or a titanium coupling agent as needed.
The average particle diameter in the present embodiment means the particle diameter at an integrated value of 50% in the particle size distribution obtained by the laser diffraction / scattering method.

(Organic filler)
In the present embodiment, the organic filler is, for example, wood flour such as timber, wood board, plywood, cutting waste such as pulp or bamboo, polishing waste, cutting saw dust, and pulverized material. In addition, although it will not specifically limit if it is wood flour, it is preferable to remove the thing containing fat like pine resin.

  Moreover, it is preferable that the particle size of the said wood flour uses the range of 50 micrometers or more and 200 micrometers or less.

(Surface treatment of surface layer)
The surface of the surface layer 300 preferably has a surface roughness in the range of 10 μm or more and 300 μm or less by the uneven processing described later.

(Explanation of uneven processing)

First, the material of the base layer 200 is charged in the first extruder 510, the base layer 200 is extruded from the first extrusion head 520, and the base layer 200 is formed by passing through the heating shaping mold 530. Then, the material of the surface layer 300 (thermoplastic resin, inorganic filler, organic filler) is put into the second extruder 560 while the base layer 200 is heated by the heating plate 550.

  The material of the surface layer 300 that has passed through the second extrusion head 570 and the coating mold 580 forms the surface layer 300 around the base layer 200.

(Polishing equipment)
Subsequently, the base layer 200 on which the surface layer 300 is formed passes through a central portion of a polishing apparatus provided in a pair of upper and lower sides.

In the present embodiment, the polishing apparatus 600 is provided in a pair of upper and lower sides, but it is sufficient that the polishing apparatus 600 is provided at least on one surface of the upper side or the lower side. After shaping the wood texture on one side of 100, the resin molded body 100 may be inverted and passed through the polishing apparatus 600 again to shape the wood texture on the upper and lower surfaces of the resin molded body 100.
Further, in addition to at least one upper or lower surface, the polishing apparatus 600 may be provided on at least one side surface of both side surfaces.

  The polishing sheet 640 is provided by winding rollers 610, 620, and 630. That is, as shown in FIG. 2, the polishing sheet 640 is disposed so as to be substantially triangular when viewed from the side of the manufacturing apparatus 400.

  In this case, the contact time between the surface layer 300 and the polishing sheet 640 can be increased, and the inorganic filler is elongated in the polishing direction on the surface of the rotating polishing sheet 640 to form a visual woodgrain pattern. be able to.

  In the present embodiment, polishing sheet 640 is preferably made of sandpaper and is within the range of 40 mesh or more and 40 mesh or less. Furthermore, it is more preferable to be within the range of mesh 60 or more and mesh 80 or less. As a result, a surface roughness in the range of 10 μm to 300 μm is formed on the surface of the surface layer 300.

In this embodiment, the polishing sheet 640 is used. However, the present invention is not limited to this. For example, a cylindrical polishing roll subjected to knurling or the like, and a cross section in a polishing direction is circular or elliptical. An endless belt that is driven to rotate, or a brush-like or comb-like one can be employed. Further, as the surface material of the polishing body, other materials such as nylon fibers and abrasive grains, resin, metal, etc. that can scratch the surface of the surface layer 300 may be adopted.
In the present embodiment, the case where the twin-screw extruder 500 and the polishing apparatus 600 are continuously provided has been described. However, the present invention is not limited to this, and the twin-screw extruder 500 and the polishing apparatus 600 are separately provided. The processing may be performed step by step.
