Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tubular body used for, for example, fishing rods and golf clubs, and a method for producing the same, and is durable regardless of particle size and having a uniform and stable glittering appearance free from spots and variations. The present invention relates to an excellent lightweight tubular body and a method for producing the same. In this case, the tubular body used for the fishing rod includes, for example, a rod, a reel, a lure and the like. Further, the tubular body used for the golf club includes, for example, a shaft, a head, and the like.
[0002]
[Prior art]
Conventionally, in various tubular bodies as described above, a plurality of particles are dispersed in the surface direction and the depth direction of the pattern layer in order to exhibit the brilliant appearance.
[0003]
[Problems to be solved by the invention]
However, when a plurality of particles are dispersed substantially uniformly over the surface direction and depth direction of the pattern layer in this way, gaps are generated between the individual particles and the orientation of the individual particles is not constant. As a result, the reflection of light varies, and the entire tubular body has a dull appearance. As a result, a desired glittering appearance cannot be obtained.
[0004]
As a method for realizing the appearance of a tubular body excellent in glitter, there is a method in which a plurality of particles are densely packed at a relatively high density over the surface direction of the pattern layer.
[0005]
As one of the methods, for example, Japanese Patent No. 2753443 proposes a tubular body (fishing tool) having an appearance with excellent luster by densely gathering particles of 30 μm or less in a pattern layer at a relatively high density. Yes.
[0006]
As another method, there is a method of uniformly arranging particles larger than 30 μm in the pattern layer.
[0007]
However, when particles larger than 30 μm are used, the boundaries between the particles become conspicuous, and the appearance of the tubular body is uneven and uneven, resulting in a homogeneous and stable glitter. It can no longer be demonstrated.
[0008]
Moreover, if particles larger than 30 μm are uniformly arranged, the amount of resin inserted therebetween increases, and as a result, it is difficult to reduce the weight of the tubular body.
[0009]
Furthermore, when particles larger than 30 μm are used, depending on the degree of density, when the tubular body is bent and deformed by external pressure, cracks may occur in the individual particles, or the individual particles may wave, Since the direction of reflection of light is not constant, bright spots and variations occur in the appearance of the tubular body, and as a result, uniform and stable glitter cannot be exhibited. Further, when cracks occur in individual particles, the durability of the tubular body itself is deteriorated.
[0010]
The present invention has been made in order to solve such problems, and is not affected by the size of the particles, and has a uniform and stable brilliant appearance free from spots and variations, and has excellent durability and light weight. It is providing the tubular body of this and its manufacturing method.
[0011]

[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a tubular body and a manufacturing method thereof according to an embodiment of the present invention will be described with reference to FIG.
[0013]
In the present embodiment, for example, a fishing rod or a golf club is assumed as the tubular body. In particular, tubular bodies used for fishing rods include, for example, rods, reels, lures and the like. Further, the tubular body used for the golf club includes, for example, a shaft, a head, and the like.
[0014]
As shown in FIGS. 1A and 1B, the tubular body 1 includes a member main body 2, a base layer 4 formed on the outer surface of the member main body 2, and a pattern layer 6 formed on the outer surface of the base layer 4. And a transparent or translucent protective layer 8 formed on the outer surface of the pattern layer 6.
[0015]
The member main body 2 can be formed of a material such as a synthetic resin, fiber reinforced plastic, metal, or ceramic. In the case where the pattern layer 6 is directly formed on the outer surface of the member main body 2, it is preferable that the outer surface of the member main body 2 is finished to be substantially mirror-like smooth so that the pattern layer 6 can be satisfactorily formed. In this case, as a method of finishing the outer surface of the member body 2 smoothly, for example, a barrel polishing method, a buffing method, or the like can be applied.
[0016]
The underlayer 4 can be formed by a method such as painting or plating. In addition, the material of the base layer 4 needs to be selected in consideration of the adhesion between the material constituting the member main body 2 and the pattern layer 6. For example, when the base layer 4 is formed by coating, an epoxy-based or urethane-based paint can be used. In this case, the thickness of the underlayer 4 is preferably 5 to 50 (or 30) μm. This is because if the thickness of the underlayer 4 is less than 5 μm, the underlayer 4 follows the unevenness of the member body 2 and the outer surface of the underlayer 4 does not become smooth, and the thickness of the underlayer 4 is 50 μm. This is because the overall weight of the tubular body 1 increases and the weight can not be reduced. The outer surface of the base layer 4 is preferably finished to have a substantially mirror-like smooth surface so that the pattern layer 6 can be satisfactorily formed.
[0017]
The protective layer 8 can be formed by a method such as painting. Further, the material of the protective layer 8 needs to be selected in consideration of the adhesion with the material constituting the pattern layer 6, and for example, a transparent or translucent synthetic resin such as an epoxy resin or a urethane resin is used. Can do.
[0018]
The pattern layer 6 is composed of a resin including a plurality of particles 10 (hereinafter referred to as large particles) having a glitter (outer shape) larger than 30 μm, and a plurality of large particles having a glitter. 10 A plurality of particles 12 (hereinafter referred to as small particles) having a glitter (size) of 30 μm or less are dispersed between the surface and the particles.
[0019]
The large particles 10 and the small particles 12 having the glitter are densely packed in a high density and flush with the pattern layer so as to reflect the light incident on the pattern layer 6 in a specific direction with regularity. 6 are arranged. In this case, “densely densely packed” means that 50 to 10,000 (preferably 500 to 5000) large particles 10 and small particles 12 are densely packed per unit area (1 mm ² ). Means. Further, “flat” means that the large particles 10 and the small particles 12 are positioned in substantially the same plane.
[0020]
As the large particles 10 and the small particles 12 having glitter, thin foils made of, for example, gold, silver, aluminum, aluminum alloy, magnesium, copper, tin, chromium, cobalt, brass, iron, stainless steel, nickel, zinc, etc. It is preferable to use the shape. Each of these thin foil-like large particles 10 and small particles 12 is formed by depositing or sputtering the metal on a film-like support substrate made of, for example, Teflon or silicone resin, and then forming a metal layer. It can be produced by peeling the layer from the support substrate and crushing.
[0021]
In this case, the large particle 10 has a size (outer shape) of 30 μm or more (greater than 30 μm) and 1 mm or less (preferably in a range of 50 μm to 500 μm), and a thickness of 3 μm or less (excluding zero). The thickness is preferably set in the range of 0.01 μm to 1 μm. On the other hand, the small particles 12 have a size (outer shape) of 30 μm or less (excluding zero), preferably in a range of 0.1 μm to 25 μm and a thickness of 2 (or 3) μm or less ( Excluding zero), preferably, it is set in the range of 0.01 μm to 1 μm.
[0022]
The resin constituting the pattern layer 6 may be a material that can stably hold the large particles 10 and the small particles 12 (for example, transparent or semi-transparent materials such as epoxy, urethane, silicone, and fluorine). Transparent synthetic resin) can be used. In this case, in order to make the large particles 10 and the small particles 12 easy to gather in the formation method of the pattern layer 6 described later, and to reduce the weight of the pattern layer 6 (the weight of the tubular body 1 thereby), the pattern layer The thickness of 6 is preferably set to 15 μm or less (preferably 10 μm or less, more preferably 1 μm (or 0.1 μm) to 6 μm (or 10 μm)).
[0023]
As a position where the pattern layer 6 is formed, a case where the pattern layer 6 is formed on the outer surface of the base layer 4 as shown in FIG. 1 or a case where the pattern layer 6 is directly formed on the outer surface of the member main body 2 although not particularly illustrated can be considered.
[0024]
In these two cases, the following two methods can be used as a method of forming the pattern layer 6.
[0025]
In the first method, the large particles 10 and the small particles 12 are mixed with a synthetic resin at a high addition rate to prepare a paint, and the paint is applied to the outer surface of the member body 2 or the base layer 4 (fully cured base layer 4). In this method, the outer surface is coated, the large particles 10 and the small particles 12 are densely adhered and adhered, and then dried and cured.
[0026]
The second method is to apply a synthetic resin (underlayer for forming the pattern layer 6) to the outer surface of the member body 2 or the underlayer 4 and leave the synthetic resin as the underlayer in an uncured state. In this method, the synthetic resin mixed with the small particles 12 is applied, the large particles 10 and the small particles 12 are densely adhered to each other and adhered, and then the synthetic resin as the base layer is completely cured.
[0027]
If the underlayer 4 (or the underlayer for forming the pattern layer 6) is in an uncured state, even when the large particles 10 and the small particles 12 are directly applied to the outer surface of the underlayer, the large particles 10 and The small particles 12 can be stably and closely packed and adhered. Further, even when the underlayer 4 (or the underlayer for forming the pattern layer 6) is in a completely cured state, the paint used for the protective layer 8 has good permeability and high adhesion to the underlayer. If it is, the large particles 10 and the small particles 12 can be directly coated on the outer surface of the underlayer.
[0028]
Further, as a method for directly coating the large particles 10 and the small particles 12 on the outer surface of the underlayer, for example, the large particles 10 and the small particles 12 are attached to the outer surface of the underlayer by electrostatic force or intermolecular force, or It may be attached to the outer surface of the underlayer by spraying, and then a predetermined paint may be applied.
[0029]
Moreover, uncured and complete curing can be appropriately adjusted according to the curing conditions (for example, the curing temperature of the resin, the curing time, etc.) of the foundation layer 4 (or the foundation layer for forming the pattern layer 6).
[0030]
In these methods, it is also preferable to form an adhesive coating on the surfaces of the large particles 10 and the small particles 12 in advance in order to improve the mutual adhesion between the large particles 10 and the small particles 12.
[0031]
When the pattern layer 6 is formed by such a method, it is preferable that the outer surface of the pattern layer 6 is finished to be substantially mirror-like smooth so that the reflected light from the outer surface of the pattern layer 6 becomes uniform.
[0032]
Here, in the first and second methods described above, a specific description will be given of a method in which the large particles 10 and the small particles 12 are densely packed and coated.
[0033]
As this coating method, for example, a spray coating method or a dipping coating method can be used.
[0034]
First, in the spray coating method, a spray gun having a nozzle diameter of 0.8 mm to 2.5 mm is used, and the proportion of the large particles 10 and the small particles 12 is 20 with respect to the total amount of paint sprayed from the spray gun. The paint is diluted with a predetermined diluting solvent so as to be not more than wt%.
[0035]
The paint is composed of a plurality of large particles 10 and small particles 12, a synthetic resin (for example, epoxy, urethane, silicone, fluorine, etc.) and a diluent solvent. By mixing the particles 12 in a synthetic resin to form a main agent and mixing a larger amount of a diluting solvent than the main agent, a paint having the above-described ratio can be made. In this case, it is preferable to constantly stir the paint with a stirrer to uniformly disperse the plurality of large particles 10 and small particles 12 in the paint. In this way, since the plurality of large particles 10 and the small particles 12 are uniformly dispersed in the paint sprayed from the spray gun, the plurality of large particles 10 and the small particles 12 are uniformly arranged by the pattern layer 6. be able to.
[0036]
By spraying such a paint from a spray gun for a predetermined time (for example, 0.5 ^second per 1 cm ² ), the large particles 10 and the small particles 12 can be densely packed in a flat manner.
[0037]
In this case, the diluting solvent may be a plurality of types of solvents (for example, acetone, toluene, IBA, methanol, IPA, butyl cellosolve, etc.) so that the large particles 10 and the small particles 12 are easily gathered in a single plane. It is preferable to use a mixture of solvents having different boiling points. When such a diluting solvent is used, when the diluting solvent evaporates from the paint during coating, convection occurs in the paint, and the large particles 10 and the small particles 12 are densely packed in a plane (specifically, Has the effect of assisting the particles in close contact with each other.
[0038]
In consideration of coating efficiency, the distance of the spray gun to the tubular body 1 is set within 300 mm (preferably in the range of 50 mm to 200 mm), and the injection pressure is 0.24 MPa or less (preferably 0.10 MPa or less). ) Is preferable.
[0039]
In addition, during coating, a synthetic resin (for example, epoxy-based, urethane-based, silicone-based, fluorine-based, etc.) contained in the paint sprayed from the spray gun wraps and protects the large particles 10 and the small particles 12. In addition to serving as a protective agent, it also serves as an adhesive for attaching the large particles 10 and the small particles 12 to the above-described underlayer 4 (or the underlayer for forming the pattern layer 6). When the viscosity of the resin is higher than the viscosity of the solvent for dilution, the large particles 10 and the small particles 12 may be obstructed from being densely arranged in a flush manner. In this case, when the content of the synthetic resin is reduced, the protective action and adhesion action of the large particles 10 and the small particles 12 are lowered. However, even in such a case, a synthetic resin (underlayer for forming the pattern layer 6) is applied to the outer surface of the member main body 2 or the underlayer 4 as in the above-described second method. If the synthetic resin is applied in an uncured state, the large particles 10 and the small particles 12 can be densely attached in a flush manner.
[0040]
Next, in the dipping coating method, it is basically possible to use a paint similar to the spray coating method described above. In this case, the opening of the tubular body 1 is plugged so that the paint does not enter the inside of the tubular body 1, and then the process goes to a dipping coating process.
[0041]
In the dipping coating process, after the tubular body 1 is immersed in the paint, the amount of adhesion of the large particles 10 and the small particles 12 can be changed by adjusting the pulling speed when the tubular body 1 is pulled up from the paint. it can. In this case, it is preferable to set the pulling speed to 1 m / min to 3 m / min.
[0042]
In the drying process after the dipping coating, the drying process is performed while rotating the tubular body 1 at a predetermined rotation speed. In this case, the rotation speed is preferably set to 50 rpm to 400 rpm.
[0043]
By setting the pulling speed and the rotation speed in this way, the large particles 10 and the small particles 12 can be closely packed and adhered in a flush manner. Specifically, the large particles 10 such that the plurality of large particles 10 are flush with each other and the plurality of small particles 12 are flush with each other between the overlapping large particles 10. 10 and the small particles 12 can be closely packed and adhered.
[0044]
In addition to the above-described coating method, for example, ironing or brush coating may be used, and in the case of partial coating, the pattern layer 6 may be transferred as a film.
[0045]
When the pattern layer 6 in which the large particles 10 and the small particles 12 are flush with each other is formed by such a coating method, the large particles 10 and the small particles 12 partially protrude from the outer surface of the pattern layer 6. In this case, however, the outer surface of the pattern layer 6 is subjected to a pressing process, and the large particles 10 and the small particles 12 partially protruding from the outer surface of the pattern layer 6 are pressed against the outer surface of the pattern layer 6, Alternatively, by removing the outer surface of the pattern layer 6 to remove the large particles 10 and the small particles 12 partially protruding from the outer surface of the pattern layer 6, the large particles 10 and The small particles 12 can be concentrated in a flush manner.
[0046]
In the pressing process, for example, the large particles 10 and the small particles 12 partially protruding from the outer surface of the pattern layer 6 may be pressed by a predetermined pressing device. In the removal process, for example, the large particles 10 and the small particles 12 partially protruding from the outer surface of the pattern layer 6 may be cut by a predetermined cutting machine.
[0047]
Then, the tubular body 1 of this Embodiment can be completed by forming the transparent or semi-transparent protective layer 8 on the outer surface of the pattern layer 6.
[0048]
As described above, according to the tubular body 1 of the present embodiment, the size (outer shape) has a size (outer shape) of 30 μm or less between the surface of the plurality of large particles 10 having a luster of 30 μm or more in size (outer shape). Since the plurality of small particles 12 having the above-mentioned glittering properties are dispersed to form the pattern layer, the small particles 12 are closely packed in the gaps P between the large particles 10 as shown in FIG. The boundary L between the large particles 10 can be made inconspicuous, and the light reflection direction can be made constant. As a result, the tubular body 1 having a uniform and stable lustrous appearance free from spots and variations can be realized. In addition, in FIG.1 (b), although the example which made the boundary L of the large particle 10 and the small particle 12 the smooth external shape is shown, the boundary L is formed when forming the large particle 10 and the small particle 12. If the irregular uneven shape is formed, the boundary L can be made inconspicuous.
[0049]
In addition, since the large particles 10 and the small particles 12 are densely packed in the pattern layer 6, even when the tubular body 1 is bent and deformed by an external pressure, cracks are generated in the individual particles 10 and 12. Or, since the individual particles 10 and 12 do not undulate and the light reflection direction can be made constant at all times, it has a uniform and stable glittering appearance free from spots and variations and is durable. The tubular body 1 having excellent properties can be realized.
[0050]
Since the large-sized particles 10 and the small particles 12 are densely packed in the pattern layer 6, the thickness of the pattern layer 6 can be reduced, so that the weight of the tubular body 1 can be reduced.
[0051]
Furthermore, according to the manufacturing method of the present embodiment, the pattern layer 6 in which the large particles 10 and the small particles 12 are densely arranged in a flush manner can be formed by the above-described coating method, so that there are no spots or variations. The tubular body 1 having a homogeneous and stable glitter appearance can be produced.
[0052]
Further, according to the manufacturing method of the present embodiment, even when the large particles 10 and the small particles 12 partially protrude from the outer surface of the pattern layer 6, by performing a pressing process or a removal process on the outer surface of the pattern layer 6, The large particles 10 and the small particles 12 can be densely arranged in the pattern layer 6.
[0053]
In the above-described embodiment, the positions of the large particles 10 and the small particles 12 densely densely arranged in the pattern layer 6 in the same plane in the pattern layer 6 are particularly limited. Although not shown, for example, as shown in FIG. 2 (a), the large particles 10 and the small particles 12 arranged in a flush manner are placed closer to the lower side of the pattern layer 6 (side closer to the base layer 4). Alternatively, for example, as shown in FIG. 2B, the large particles 10 and the small particles 12 arranged in a plane may be positioned closer to the upper side of the pattern layer 6 (on the protective layer 8). You may concentrate and position on the side (substantially adjacent side). In addition to this, although not particularly illustrated, the large particles 10 and the small particles 12 arranged in a plane may be concentrated and positioned in the middle of the pattern layer 6.
[0054]
In the above-described embodiment, the tubular body 1 in which the pattern layer 6 is formed between the base layer 4 and the protective layer 8 has been described. However, the present invention is not limited to this, and for example, FIG. ), The pattern layer 6 may be formed directly on the outer surface of the member main body 2, or the protective layer 8 may be formed as a decorative layer. When the protective layer 8 is formed as a decoration layer, when a plurality of microparticles 14 (for example, spherical bodies, hemispherical bodies, etc.) are dispersed in the protective layer 8, light is scattered by these microparticles 14, The appearance decorative effect can be increased. In this case, the fine particles 14 may have a size (outside dimension) that can scatter light, and may be changed according to the purpose of use of the tubular body 1. do not do.
[0055]
In the above-described embodiment, the tubular body 1 having the single pattern layer 6 has been described. However, the present invention is not limited to this, and the pattern layer 6 may have a plurality of layers. However, when the pattern layer 6 is formed into a plurality of layers, it is preferable that these pattern layers 6 are concentrated in one place and adjacent to each other.
[0056]
Further, in the above-described embodiment, the large particles 10 and the small particles 12 may be in close contact with each other to form one film 16 (see FIG. 2C), and the film 16 may be incorporated into the pattern layer 6. . If the large particles 10 and the small particles 12 are brought into close contact with each other to form a single film 16, the light reflection direction can be made more constant (stabilized). Sexual appearance can be improved.
[0057]
Furthermore, in the above-described embodiment, the case where the large particles 10 and the small particles 12 are densely packed in the pattern layer 6 has been described. However, the present invention is not limited to this, and only the large particles 10 are used. May be used. Even when only the large particles 10 are used, the plurality of large particles 10 are densely packed so as to reflect the light incident on the pattern layer 6 in a specific direction with regularity by the above-described coating method. In addition, since they can be arranged so as to be flush with each other, it is possible to realize a tubular body 1 having a homogeneous and stable glitter appearance free from spots and variations.
[0058]
Further, even when the pattern layer 6 is formed on the outer surface of the member main body 2 or the base layer 4 having some unevenness (for example, unevenness generated when a golf shaft is formed), a certain degree of appearance decoration effect can be obtained.
[0059]
In the above-described embodiment, if the member body 2 is made of FRP made of carbon fiber or glass fiber, the patterned layer 6 in which the large particles 10 and the small particles 12 are mixed even if the tubular body 1 is greatly bent. However, it can prevent peeling or cracking.
[0060]
Moreover, in embodiment mentioned above, although the member main body 2 outer surface is finished smoothly, it is not limited to this, For example, a tape formed when forming member main bodies 2, such as a golf shaft and a tub tube The pitch pattern may be left as it is.
[0061]
