Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod which can easily remove water droplets, does not easily smell, and has excellent fishing line guiding properties.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Application Laid-Open No. 5-268858 discloses that water-repellency is obtained by mixing fluorine resin particles into a resin having high adhesion and firmly adhering to a rod tube made of urethane resin or acrylic resin. A through fishing rod in which an improved resin layer is formed on the inner surface of a rod tube is disclosed.

[0003]

However, in the above-mentioned prior art, a resin having high adhesiveness is used as a binder resin of a coating material to be applied, so that although the adhesiveness is excellent, high water repellency is obtained. I couldn't. That is, the contact angle of such a resin with water was as small as about 90 to 110 degrees, and at most less than 120 degrees.

[0004] Therefore, after the fishing rod is used, water droplets remain inside the rod tube, and it is necessary to perform troublesome care for removing the water droplets. In addition, if the fishing rod is not properly maintained and the fishing rod is stored with water droplets attached, the fishing rod may smell on the fishing rod due to bacteria or the like, which may cause discomfort. On the other hand, instead of a resin film, it is conceivable to form a metal film that smells and does not easily adhere, but it is difficult to employ such a metal because the metal is easily corroded.

The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a fishing rod which is easy to remove water droplets, hardly smells, does not cause corrosion, and has excellent fishing line guide properties. To provide.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a rod tube formed by winding a prepreg in which a reinforcing fiber is impregnated with a synthetic resin has water repellency on both inner and outer surfaces. A fishing rod having a synthetic resin coating and having at least a water repellency on the inner surface of a rod tube of 130 degrees or more in water contact angle is provided.

As described above, the characteristics of the fishing rod of the present invention are that a water-repellent coating is formed on both the inner and outer surfaces of the rod tube, and at least the water-repellent coating on the inner surface is made super-water-repellent.

In the fishing rod of the present invention, the super-water-repellent film formed on at least the inner surface of the rod tube has a water contact angle of 130.
Degrees or more, preferably 140 degrees or more, particularly preferably 15 degrees or more.
It has a very high water repellency, such as 0 to 180 degrees. Such a super water-repellent coating can be obtained, for example, by mixing water-repellent particles with a water-repellent resin and forming a fine uneven surface on the surface.

Such a super water-repellent coating can be formed not only on the inner surface of the rod tube but also on the outer surface. By forming the super water-repellent coating on both the inner and outer surfaces of the rod tube, water droplets can be more reliably removed, and the maintenance of the fishing rod is further facilitated.

[0010] Of the water-repellent coatings on the inner and outer surfaces of the rod tube, the water-repellent coating on the outer surface has a higher hardness and higher adhesion than the water-repellent coating on the inner surface, and the water-repellent coating on the inner surface is the outer surface. It is preferable to make the film higher in water repellency than the water repellent film described above. By doing so, the water-repellent coating on the outer surface that is easily peeled and scratched is prevented from being peeled or scratched, and the inner surface where it is desired to completely remove water droplets can be made more water-repellent. Therefore, the object of the present invention can be effectively achieved.

Examples of the water-repellent resin include a fluorine-based resin and a silicon-based resin. Although other materials can be used as the water-repellent resin, the water contact angle is 13
It is preferable to use a material having a surface property of 0 ° or more, preferably 140 ° or more.

The water-repellent particles include ethylene tetrafluoride resin, ethylene tetrafluoride resin-hexafluoropropylene copolymer resin, ethylene trifluoride chloride resin, vinyl fluoride resin,
Vinylidene tetrafluoride resin, ethylene tetrafluoride-perfluoroalkyl vinyl ether copolymer resin, ethylene fluoride resin
Examples thereof include ethylene copolymer resins, ethylene-trifluoride ethylene copolymer resins, and silicon oxide and silicon resins.

The thickness of the super water-repellent coating is 1 μm to 100 μm
Can be set arbitrarily within the range, but is preferably 3 μm to 30 μm, and particularly preferably 3 μm to 20 μm. When the projection for the fishing line guide is provided, the projection is formed to have a thickness such that the top of the projection is exposed, and the fishing line is received at the top of the wear-resistant projection. Can be prevented.

The water-repellent particles to be mixed with the water-repellent resin are preferably not of a single shape and size but of two or more kinds of various shapes and sizes. By using the water-repellent particles of various shapes and sizes, the unevenness of the surface of the super-water-repellent coating can be made complex, and the water repellency can be further improved.

It is preferable that the ratio of the water-repellent particles on the surface of the super-water-repellent coating is larger than the ratio of the water-repellent particles on the rod tube side. This is based on the physical properties of the material, for example, utilizing the difference in specific gravity between the water-repellent resin and the water-repellent particles, utilizing centrifugal force when forming the coating, or stepping the water-repellent resin having a different content of the water-repellent particles. It can be achieved by coating a plurality of times. As described above, by increasing the ratio of the water-repellent particles on the surface of the super-water-repellent coating to that on the rod tube side, the water-repellency of the surface of the super-water-repellent coating can be further increased, and the resin as the binder is By increasing the number on the rod pipe side, the adhesion to the rod pipe can be relatively improved.

The mixing ratio of the water-repellent particles in the water-repellent coating is as follows:
It is preferable to make it larger than 30% (area ratio of the cross section), and more preferable to be in the range of 40 to 70%. Thereby, the protrusion of the water-repellent particles can be increased, and a high water-repellent surface can be obtained.

Abrasion-resistant particles can be mixed into the super water-repellent coating. In this case, by forming the wear-resistant particles so as to protrude from the surface of the water-repellent coating, even if the fishing line comes into contact with the surface of the water-repellent coating, it is possible to prevent early wear of the water-repellent coating.

The size of the wear-resistant particles is not particularly limited, but is preferably larger than the size of other particles contained in the water-repellent coating, for example, the water-repellent particles. As a result, a plurality of types of particles having different sizes protrude, and a complex uneven surface can be formed. Note that the amount of the wear-resistant particles is desirably smaller than the amount of the water-repellent particles.

As described above, the durability of the water-repellent film can be improved by forming a complex uneven surface composed of the unevenness due to the wear-resistant particles and the unevenness due to the aggregation of the water-repellent particles on the surface of the water-repellent film. In addition, the water repellency can be further improved. In particular, when the water-repellent particles and the wear-resistant particles have different properties such as a material, an uneven surface having characteristics according to the properties can be formed.

The mixing ratio of the abrasion-resistant particles is not particularly limited, but is suitably 1% by weight or more, usually 3 to 30% by weight.

The water-repellent coating of the fishing rod of the present invention can be formed by a coating method using a spray, a dipping method (removing unnecessary portions after injecting a coating solution), brushing, etc. It can also be performed by winding around the outside of gold, winding an FR prepreg thereon, and heating and forming by a conventional method. Further, it can be formed by using a plating method.

A spiral or ring-shaped projection made of a wear-resistant material can be provided on the inner surface of the rod tube. This projection functions as a fishing line guide. A ring-shaped or spiral-shaped projection can be provided on the outer surface of the rod tube. The projections are provided for preventing the fishing line from adhering and for improving durability.

In the fishing rod of the present invention, the (super) water-repellent coating formed on the inner and outer surfaces of the rod tube is summarized as follows.

1) Water repellency At least the water repellent coating on the inner surface has a contact angle with water of 13
0 ° or more, preferably 140 ° or more, particularly preferably 1 °
Super water repellent of 50 to 180 degrees. The water-repellent film formed on the outer surface is also preferably super-water-repellent. Even in this case, it is preferable that the super-water-repellent film on the inner surface has higher water repellency than the super-water-repellent film on the outer surface.

As described above, by making at least the water-repellent coating on the inner surface of the rod super-water-repellent, water and dust hardly adhere to the rod tube, and the fishing rod can be easily maintained. That is,
Water droplets can be removed without wiping the inner surface of the rod tube with a cloth or the like. Further, the line resistance in a narrow space when the fishing line is passed through can be reduced.

2) Adhesion It is preferable that the adhesion of the water-repellent coating on the outer surface is higher than the adhesion of the water-repellent coating on the inner surface. As described above, by increasing the adhesiveness of the water-repellent coating on the outer surface, the water-repellent coating on the surface is generally easier to peel off from the rod tube, so that the durability can be balanced.

In order to improve the adhesion, it is preferable that the pencil hardness of the water-repellent coating on the inner surface is 2B to H, and the pencil hardness of the water-repellent coating on the outer surface is 2H to 5H.

3) Hardness The pencil hardness of the water-repellent coating on the outer surface is preferably higher than the pencil hardness of the water-repellent coating on the inner surface. In particular, the pencil hardness of the water-repellent coating on the inner surface is preferably set to H to 3B, and the pencil hardness of the water-repellent coating on the outer surface is preferably set to H or more, thereby preventing scratches even when hitting an object. I can do it.

4) Mixing of Water Repellent Particles It is preferable that the mixing amount of the water repellent particles into the water repellent coating on the inner surface is larger than the mixing amount of the water repellent particles into the water repellent coating on the outer surface. Further, it is preferable that the particle size of the water-repellent particles mixed into the water-repellent film on the inner surface is larger than the particle size of the water-repellent particles mixed into the water-repellent film on the outer surface. By doing so, the water repellency of the water repellent coating on the inner surface can be made higher than the water repellency of the water repellent coating on the outer surface.

5) Height and number of protrusions on the surface of the water-repellent coating on the surface of the water-repellent coating (0.5 to 2 m)
m) is the height of the protrusions on the surface of the water-repellent coating on the inner surface (0.2 to
0.6 mm).

In the case of a spiral shape, the number of projections on the surface of the water-repellent coating on the inner surface is increased to 3 to 30 mm.
The number of protrusions on the surface of the water-repellent coating on the outer surface is preferably reduced to several (10 or less) with one rod tube. The protrusions on the surface of the water-repellent coating on the inner surface improve the guideability of the fishing line,
The projections on the surface of the water-repellent coating on the outer surface are provided to reduce the line resistance and to prevent the fishing line from adhering and reduce the line resistance.

6) Thickness of Water Repellent Coating It is preferable that the thickness of the water repellent coating on the inner surface is larger than the thickness of the water repellent coating on the outer surface. The water-repellent coating on the outer surface is desirably formed in combination with a base layer including a pattern layer and a decorative layer. By making the water-repellent coating transparent or translucent, the underlying decorative layer is visible, and the decorativeness of the appearance is improved.

7) Wear-Resistant Particles The particle size of the wear-resistant particles mixed into the water-repellent coating on the inner surface should be larger than the particle size of the wear-resistant particles mixed into the water-repellent coating on the outer surface. preferable. By reducing the particle size of the wear-resistant particles mixed into the water-repellent coating on the outer surface, it is possible to prevent the wear-resistant particles from falling off.

A water-repellent coating is provided to maintain water-based properties. In this case, in the original rod tube 2, a water-repellent coating is applied to a portion where the fishing line 16 contacts. Although FIG. 1 shows a through-type swing rod, the present invention can be applied to, for example, a fishing rod provided with an outer guide (a fishing rod that guides the fishing line 16 along the outside of the rod pipe). .

The original rod pipe 2, the middle rod pipe 6, and the head rod pipe 10
Since the super-water-repellent coatings applied to the inner peripheral surface are the same, in the following description, as an example, at least the inner peripheral surface of the inner rod pipe 6 reduces the frictional resistance of the fishing line 16 and The case where a super-water-repellent coating for maintaining excellent water-repellency over a long period of time will be described.

It is a tapered hollow rod tube.

As the reinforcing fiber, carbon, glass, boron, alumina, aramid, or the like can be used, and as the base material (matrix), an epoxy resin, a poly resin, or a phenol resin can be used.

As shown in FIG. 2, a super-water-repellent coating is formed on the inner and outer surfaces of the rod tube main body, and a spiral projection as a fishing line guide is formed on the inner peripheral surface of the rod tube main body 22. 24 are formed. This projection 24 is made of FR

A ring-shaped projection 25 is formed on the outer peripheral surface of the rod tube main body 22. This ring-shaped projection 25
Can be formed by bonding a ring-shaped member, applying a paint in a ring shape, or by FRP. The ring-shaped projections 25 are provided to prevent the fishing line from adhering and to improve durability.

It is also possible to eliminate one or both of these projections.

FIG. 3 is a diagram showing a cross-sectional structure of the rod pipe body 22 according to one embodiment of the present invention. As shown in FIG.
The rod tube main body 22 has a three-layer structure of an inner layer 22a, an intermediate layer 22b, and an outer layer 22c. Inner layer 22a and outer layer 2
2 is composed of a carbon circumferential fiber layer, a glass scrim cloth layer (woven fabric layer) or a carbon axial fiber layer, or a combination thereof, and the intermediate layer 22b is mainly composed of an axial fiber layer or an inclined fiber layer. It is composed of layers. In addition, the material and the number of laminations constituting the rod tube main body 22 are not limited to these, and can be arbitrarily selected.

As shown in FIG. 3, a plurality of projections 24 having a predetermined height are formed at a predetermined pitch on the inner peripheral surface of the rod tube main body 22, and a super-repellent material having a fine uneven surface is formed. The aqueous coating 28 is fixed. A super water-repellent coating 29 is fixed to the outer peripheral surface of the rod tube main body 22.

The super-water-repellent coating 28 has a complex uneven surface having not only fine unevenness but also fine unevenness having a smaller depth. While fine irregularities are formed by adding water-repellent coating particles to the water-repellent resin, fine irregularities increase the amount of solvent on the surface when forming the water-repellent coating, Can be formed by evaporating. Alternatively, as described later, it can be formed by mixing wear-resistant particles having a larger particle size than the water-repellent particles.

In the present embodiment, the term “fastening” refers to, for example, painting (liquid, powder, etc.), printing, wrapping of a prepreg or a resin film, vapor deposition, plating, super adhesion, etc. This means that the coatings 28 and 29 are formed. The term “super water-repellent” means that the contact angle of a water droplet is at least 130 degrees, preferably 140 degrees or more, and more preferably 150 degrees to 180 degrees.

The plurality of projections 24 are preferably made of a wear-resistant material. Examples of usable wear-resistant materials include, for example, a fiber reinforced resin using ceramic fiber, carbon fiber, glass fiber, or the like, a material using organic fiber such as PET, aramid, PTFE, or PE as the reinforcing fiber, or a synthetic fiber. A resin film, a thread, a ceramic material (ring shape) or the like can be used. In addition, these projections 2
4 is 0.1 to 1 mm, preferably 0.2 to 1 mm.
It is preferable to set the range to 0.6 mm. Further, the pitch of the plurality of projections 24 is preferably set in the range of 2 to 20 mm, and more preferably, in the range of 3 to 10 mm.

The super-water-repellent coating 28 is fixed over a region between the plurality of projections 24, and the thickness thereof is set smaller than the height of the projections. In this case, the thickness of the super water-repellent coating 28 is 1 to 100 μm, preferably 3 to 100 μm.
It is preferable to set it in the range of 20 μm to 20 μm.

Note that, as shown in FIG.
Is the thinnest at the top 28a of the projection 24, the thickest at the base 28b of the projection 24, and shows the average thickness in the region 28c between the projections 24.

The super water-repellent coatings 28 and 29 are formed using a water-repellent resin such as a fluororesin or a silicone resin in which water-repellent particles such as fluororesin particles are dispersed and mixed. For example, in a film forming method as described later, a prepreg sheet is wound around the rod pipe main body 22.
By forming the water-repellent resin mixture on the prepreg sheet in advance when forming the
Is formed on the inner peripheral surface of the rod tube main body 22 at the same time as the above is completed.

As described above, according to the present embodiment, a plurality of projections 24 are formed on the inner surface of the rod tube main body 22 at a predetermined pitch, and the super-water-repellent coatings 28 and 29 are formed on the inner and outer surfaces. By providing the fishing rod, it is possible to provide a fishing rod capable of reducing the frictional resistance of the fishing line 16 and maintaining excellent water repellency for a long period of time. That is, for example, even when seawater or water gets on the fishing rod, water droplets and the like can be quickly removed by the minute uneven surface, so that water droplets and the like are prevented from adhering to the super water-repellent coatings 28 and 29. Can be. That is, when water droplets or the like adhere to the super water-repellent coatings 28 and 29, the fishing line 16 is drawn to the water-repellent coating 28 by the water droplets and the like, and the fishing line 16 and the super water-repellent coating 2
8 and the contact state increases. However, adhesion of water droplets and the like on the super-water-repellent coating 28 can be prevented by the minute uneven surface, so that the contact of the fishing line 16 with the super-water-repellent coatings 28 and 29 can be reduced, and the line resistance can be reduced. In addition, since the contact of the fishing line is small, the super water-repellent coatings 28 and 29 can be protected.

FIG. 4 shows a super water-repellent coating 28 formed on the inner peripheral surface of the rod tube body 22 according to another embodiment of the present invention.
It is sectional drawing which expands and shows 2000 times. In this example, the super-water-repellent coating 28 is formed by mixing the water-repellent particles 26 with a water-repellent resin as a binder, and the surface thereof is
It is composed of a fine uneven surface 30a and a flat surface 30b.

In the super-water-repellent coating 28, the amount of the water-repellent particles 26 on the surface side is distributed more than on the rod tube main body 22 side. The particle size of the water-repellent particles 26 is 0.1 μm to 1 μm, and the depth of the unevenness is 2 to 3 times the particle size of the water-repellent particles 26.
Double or more.

An underlayer may be formed between the rod body 22 and the super water-repellent coating 28 during molding or by painting. The material and the number of layers of the underlayer can be arbitrarily selected.

The minute uneven surface of the super-water-repellent coating 28 is formed by combining concave portions and convex portions. In this case, the concept of “small” refers to such a small size that air that enters a concave portion having minute irregularities is retained in the concave portion and water droplets do not enter the concave portion. As a specific example, when the super-water-repellent coating 28 is viewed on a plane, the combination number of the concave portions and the convex portions is 100 or more or 1000 or more per unit area (for example, 1 mm ² ). Or more, preferably
It means that 5000 to 1,000,000 or more are formed. In other words, the concept of “micro” means that the height difference between the concave portion and the convex portion is 10 μm or less,
Preferably, the pitch is 0.1 to 5 μm, and the pitch between the concave portion and the convex portion is 10 μm or less, preferably 0.1 μm.
It means that it is set to 1 to 5 μm.

Further, the concept of “fine” of the “fine uneven surface” used in the present specification means that the air that has entered the concave of the minute uneven surface is held in the concave portion, and that the water droplet does not enter the concave portion. It is the same as “small” in terms of minuteness, and the number may be smaller than “small”, but may be about the same as “small”. For example, as a specific example, the super-water-repellent coating 28
When viewed on a plane, the number of combinations of concave portions and convex portions is converted into a unit area (for example, 1 mm ² ),
10 or more or 100 or more, preferably 1000
It means that 500,000 or more are formed. In other words, the concept of “fine” means that the height difference between the concave portion and the convex portion is 10 μm or less, preferably 0.2 to 5 μm, and the difference between the concave portion and the convex portion. Pitch is 100 μm or less, preferably 0.2 to 5
It means that it is set to μm.

When the water-repellent particles 26 are densely arranged on the rod tube main body 22 side, the fastening (adhesion) area between the rod tube main body 22 and the super water-repellent coating 28 is reduced, and as a result, the rod pipe main body 22
Since the adhesion (adhesion) of the super water-repellent coating 28 to the water-repellent coating 28 may decrease, the water-repellent particles 26 are used in the present embodiment.
Are concentrated on the surface side of the water-repellent coating 28 and in the vicinity thereof.

By concentrating the water-repellent particles 26 on the surface side of the super-water-repellent coating 28 and in the vicinity thereof, the boundary surface between the rod tube main body 22 and the super-water-repellent coating 28 has less water-repellent particles 26. Since it can be set to a state where the rod tube main body 22 is almost or completely absent, a fastening (adhering) area between the rod pipe main body 22 and the super water-repellent coating 28 can be increased. As a result, the adhesion (adhesion) of the super water-repellent coating 28 to the rod tube main body 22 can be improved. Further, by increasing the proportion of the water-repellent particles 26 on the surface side, the water repellency of the surface of the super water-repellent coating 28 can be further increased.

The super-water-repellent coating 28 in which the ratio of the water-repellent particles 26 is increased on the surface side can be formed, for example, by utilizing the difference in specific gravity between the water-repellent particles and the binder.
That is, in the curing stage such as heat curing or light curing of the coating,
Alternatively, in a stage before that, it is possible to adjust the ratio of the water-repellent particles 26 on the surface side by using centrifugal force.

The water repellent particles 26 can be raised on the surface by the difference in surface tension. Alternatively, a paint having a small proportion of the water-repellent particles 26 may be applied, a paint having a small proportion of the water-repellent particles 26 may be applied on the resin layer in a semi-cured state, and the inner and outer layers may be heated and cured. .

FIG. 5 shows a super water-repellent coating 28 formed on the inner peripheral surface of a rod tube body 22 according to still another embodiment of the present invention.
2 is a cross-sectional view showing 2,000 times magnification. In this example, two underlayers, that is, a high adhesion layer 32a and a coating layer 32b are provided between the rod tube main body 22 and the super water-repellent coating 28, and the water-repellent coating 28 is added to the water-repellent particles 26. And wear-resistant particles 34. As the wear-resistant particles 34, silica, alumina, glass, SiC, stainless steel, or the like can be used.

It is preferable that the wear-resistant particles 34 have a particle diameter larger than the water-repellent particles 26 contained in the water-repellent coating 28 and smaller than the thickness of the water-repellent coating 28. The particle size of the water-repellent particles 26 is, for example, 0.1
μm to 1 μm, and the particle size of the wear-resistant particles 34 is, for example, 0.2 μm to 5 μm.

Therefore, the water-repellent coating 28 contains the small-diameter water-repellent particles 26 and the large-diameter abrasion-resistant particles 34 in the water-repellent resin as a binder. Provide a finished surface. That is, the relatively small water-repellent particles 26 form a relatively smooth fine uneven surface, and the large-diameter wear-resistant particles 3
A fine uneven surface with 0 protruding is obtained.

As described above, in the present embodiment, in order to further improve the water repellency of the water repellent coating 28, the water repellent coating 2
8, the water-repellent particles 26 are mixed into the water-repellent particles 26, whereby fine irregularities due to the aggregation of the water-repellent particles 26 are further formed on the fine irregular surface of the water-repellent coating 28 formed by the wear-resistant particles 34. ing.

That is, the aggregate of the water-repellent particles 26 becomes a convex portion, and the gap between the convex portions becomes a concave portion.

In the method of forming the water-repellent film 28 using the water-repellent particles 26, for example, a water-repellent material mixture (synthetic resin) in which the water-repellent particles 26 are dispersed and mixed is fixed to a prepreg sheet in advance. Then, after winding the prepreg sheet to form the rod tube main body 22, a heat treatment is applied to the water-repellent material mixture to expose the water-repellent particles 26, and as a result, the water-repellent particles 26 and the water-repellent particles 26 A minute uneven surface corresponding to the combination shape with the gap between them is formed.

As another film forming method, for example, after the rod tube body 22 is completed, a water-repellent material mixture in which the water-repellent particles 26 are dispersed and mixed is laminated (sprayed) on the inner peripheral surface of the rod tube body 22. Coating) and subjecting the water-repellent material mixture to heat treatment.

In the water-repellent film 28 having the structure shown in FIG. 5, the ratio of the water-repellent resin to the total amount of the film is, for example, 6%.
It is preferred to be 0 or less than 50% by weight. By using the amount of the water-repellent resin in such a range, it is possible to easily form the unevenness on the surface of the water-repellent coating 28 deeply.

The high adhesion layer 32 a is provided for roughening the inner surface of the rod tube main body 22 and improving the adhesion of the water-repellent coating 28. As a material constituting the high adhesion layer 32a,
An acrylic resin, an epoxy resin, a polyurethane resin, a silicone resin, and the like can be given. Note that the high adhesion layer 32a is not necessarily provided. High adhesion layer 32
