Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod having a surface decoration and a method of manufacturing the same.

[0002]

2. Description of the Related Art As a rod body for a fishing rod having a surface decoration of this kind, a prepreg obtained by impregnating a thermosetting resin such as epoxy into carbon-based reinforcing fiber is conventionally wound around a mandrel to form a rod material. At the same time, a forming tape such as polyester or polypropylene for molding is spirally wound around the outer surface of the rod material and fired. After firing, the forming tape is peeled off, and the outer surface of the rod material from which the forming tape is peeled is smoothed. After the finishing, the coating is applied after the finishing to form a resin coating layer. In general, the finishing process described above removes the spiral irregularities attached to the surface of the rod material with a molding tape and smoothes the surface (evening out the irregularities), and at the same time, paints the paint on the smooth surface. In order to roughen the surface in order to improve the surface roughness, a method of performing a polishing process using a centerless polishing machine (including a belt sander polishing machine) and then performing a coating process has been adopted. The reason why the uneven surface is smoothed in this way is that if the coating is performed while the uneven surface is left, the coating thickness of the convex portion cannot be sufficiently secured, and there are many cases where uneven coating is caused. In order to apply the coating, the finishing step as described above was required. Then, a metal interference thin film layer is formed by physical vapor deposition on the coating layer formed by performing the above-described finishing and then coating, and the surface is decorated. In the above, a resin layer is provided between a prepreg layer containing a carbon-based reinforcing fiber and a metal interference thin film layer, for example, a metal interference thin-film layer is provided directly on a prepreg layer containing a carbon-based reinforcing fiber. The purpose is to avoid the electrolytic pitting phenomenon that occurs in the event of the occurrence.

[0003]

However, when the above-mentioned finishing method is employed, the reinforcing fibers located in the projections are cut, often leading to a reduction in the strength of the rod itself.
In order to eliminate coating unevenness between the concave portion and the convex portion, it is necessary to increase the film thickness, but this tends to cause an increase in the weight of the rod itself. Therefore, the coating thickness tends to become thinner, and when the coating thickness becomes thinner, coating unevenness is likely to occur, which may hinder the insulation performance. That is, merely providing a resin coating layer between the carbon fiber prepreg and the physical vapor deposition layer to form an insulating layer is not sufficient in terms of insulating performance. An object of the invention according to claim 1 is to provide a fishing rod for a fishing rod that can sufficiently exhibit insulation performance and can be reduced in weight.

[0004]

[Means for Solving the Problems]

[Structure] A characteristic feature of the invention according to claim 1 is that a rod material is composed of a lower prepreg layer made of carbon-based reinforcing fiber and resin and an upper prepreg layer made of reinforced fiber and resin having little or no electrical conductivity. Is formed, and a metal interference thin film layer that develops color using light beam interference is directly laminated on the outer peripheral surface of the spiral ruggedness of the upper prepreg layer in the rod material. It is on the street.

[Operation] In other words, since the material provided as the insulating layer is made of glass fiber and is a prepreg sheet, the thickness can be made uniform as compared with the case of applying a coating, and the insulating performance is reduced by the thickness unevenness. high. In addition, since it is not necessary to increase the thickness in consideration of coating unevenness as in the case of coating, it is possible to reduce the weight, and it is not necessary to grind the outer peripheral surface of the spiral unevenness, and the breakage of the reinforcing fiber is reduced. The strength is reduced and the strength is not reduced.

[Effect] As a result, it is possible to provide an easy-to-handle rod which does not have a weight while improving the strength in terms of the surface decoration effect by the interference thin film layer as well as the painted surface. I have reached. Furthermore, since the electrically conductive reinforced fibers represented by glass and the like also have an elastic modulus comparable to that of the carbon-based reinforced fibers, the carbon-based reinforced fibers were used in the prepreg using the electrically-conductive reinforced fibers. The prepreg can be substituted, and there is no need to provide a dedicated layer for preventing electrolytic corrosion.

An object of the invention according to claim 2 is to provide a fishing rod for a fishing rod in which the outermost layer surface is made smoother while the insulation performance is improved as compared with the conventional one.

According to a second aspect of the present invention, in the first aspect, a resin coating layer is formed between the upper prepreg layer and the interference thin film layer. The operation and effect are as follows.

[Operation] In addition to the same operation as the operation of the invention according to claim 1, the following operation is also provided. That is, since the upper prepreg layer and the coating layer form an insulating layer, the thickness of this portion is thicker than when only the upper prepreg layer is used, and the effect of preventing electrolytic corrosion can be enhanced. In addition, since the effect of preventing electrolytic corrosion is originally high only with the upper prepreg layer, the function of the resin layer can be narrowed down to only a smooth outer surface, and it is not necessary to pay attention to uneven thickness.
Thereby, there is an effect that the outer surface of the interference thin film layer can be made smooth.

[Effect] As a result, the electrolytic corrosion prevention effect is high,
It has become possible to provide a rod that can easily perform finishing polishing and painting from a place where the outer surface has high smoothness. An object of the invention according to claim 3 is to propose a method for efficiently manufacturing a fishing rod for a fishing rod according to the invention according to claim 1.

According to a third feature of the present invention, a carbon-based reinforcing fiber is impregnated with a resin and a plurality of layers of prepreg are formed. A narrow width tape is spirally wound along the axial direction of the rod material on the outer peripheral surface of the rod material formed by polymerizing and winding the prepreg formed by the above process, and the rod material in a state where the tape is wound. After firing, the tape is peeled off after firing, and a metal deposit is directly attached to the outer peripheral surface of the spiral unevenness remaining on the surface of the rod material by a physical or chemical vapor deposition method, thereby causing interference of light rays. Is used to form an interference thin film layer that develops color, and its operation and effect are as follows.

[Operation / Effect] In other words, the process from the step of winding the prepreg into a plurality of layers to the step of peeling off the tape after firing is a general rod manufacturing process, and therefore will not be described here. However, a prepreg provided with carbon-based reinforcing fibers and a prepreg provided with glass-based reinforcing fibers are superposed and integrally formed. Therefore, unlike the case of painting, the formation of the anti-corrosion layer does not need to be performed in a separate step, and can be achieved simultaneously in the process of forming the rod material, so that the manufacturing process can be shortened. And, in order to form the interference thin film layer, a method of evaporating a thin film material is adopted, so that even if the thickness is thinner than the coating, it can be applied evenly to the whole,
It has become possible to provide a lightweight and highly decorative rod body.

[0013] The object of the invention according to claim 4 is as follows.
Another object of the present invention is to propose a method for efficiently manufacturing a fishing rod for a fishing rod according to the present invention.

According to a fourth aspect of the present invention, a plurality of layers of a prepreg formed by impregnating a resin with carbon-based reinforcing fibers and a prepreg formed by impregnating a resin with glass-based reinforcing fibers are polymerized. On the outer peripheral surface of the rod material formed by winding, a narrow width forming tape is spirally wound along the axial direction of the rod material, and the rod material in a state in which this tape is wound is fired, and the tape after firing is fired. Peeling off, applying a coating to the outer peripheral surface of the spiral unevenness remaining on the surface of the rod material to form a resin-coated surface, and performing a polishing action on the outer surface of the coating, physical or chemical vapor deposition A method of depositing a metal deposit by a method to form an interference thin film layer that develops a color by using the interference of light rays is as follows.

[Function / Effect] In forming the resin layer, it is not necessary to pay much attention to the effect of preventing electrolytic corrosion.
What is necessary is just to apply | coat so that the outer surface of this coating layer may have the thickness as much as possible smooth. The object of the invention according to claim 5 is:
It is an object of the present invention to provide a fishing rod body that enhances a design feeling and the like by an interference thin film layer.

According to the fifth aspect of the present invention,
In the configuration according to claim 1, 2, 3, or 4, the interference thin film layer is composed of upper and lower two layers on which different vapor depositions are deposited, and the lower layer of the upper and lower two layers is a vapor deposition substance. The point is that chromium is used and the upper layer uses titanium oxide as a deposit, and the operation and effect are as follows.

[Function / Effect] In addition to providing a coloring that cannot be obtained with a single layer, a chromium layer is disposed below the layer in consideration of corrosion resistance, weather resistance, heat resistance, etc. Meanwhile, by arranging titanium oxide with excellent weather resistance, heat resistance, etc. in the upper layer, it is possible to make it also excellent in design, selecting and combining the deposited material used for the upper layer and the deposited material used for the lower layer It is possible to provide a rod that can be used and exhibits effects that cannot be achieved with a single layer.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a prepreg obtained by laminating four layers of prepregs in which resin is contained in aligned carbon-based reinforcing fibers, and further comprising a prepreg in which resin is contained in cloth-like glass-based reinforcing fibers. Layers are arranged and wound to form a rod material, and a metal interference thin film layer is formed on the outer surface of this rod material by physical vapor deposition, and carbon-reinforced with a prepreg containing resin in glass-based reinforcing fibers. Provided is a fishing rod capable of preventing electrolytic corrosion at a boundary between a prepreg having fibers and a metal interference thin film layer.

When a resin coating layer is provided between a prepreg containing a resin in a cloth-like glass-based reinforcing fiber and an interference thin film layer made of metal, the effect of preventing electrolytic corrosion is high and the coating of resin is performed. The outer surface of the layer can be polished smoothly, and the outer surface of the interference thin film layer laminated on the coating layer can be smoothed.

The prepreg in which the resin is contained in the glass-based reinforcing fiber may be not a cloth but a uniform one.
