Description

The present invention relates to a fishing rod having a ceramic coating layer or an interference thin film layer in which a ceramic material is formed into a film by a physical method.

Interference thin film layer by physical vapor deposition directly on the surface of the cocoon material for the purpose of reducing the weight of the cocoon and avoiding the strength reduction of the cocoon itself due to the cutting of the reinforcing fiber in the process of grinding and removing the spiral uneven surface There was a fishing rod provided with (refer patent document 1).

JP-A-9-172912 (paragraph number [0024] and FIG. 2).

Certainly, weight reduction and strength maintenance have been achieved by the above-described configuration, but reinforcing fibers are exposed along with the resin on the surface of the cocoon material, and before the cocoon material is fired. Since the spiral concavo-convex surface which is the winding trace of the molding tape for winding the heel material is exposed, even if the interference thin film layer is formed directly on it, the interference thin film layer is formed due to the presence of reinforcing fibers, etc. In some cases, the glitter due to the interfering light beam was not sufficient.

The object of the present invention is to provide a fishing rod that retains a high decorative appearance and is difficult to be damaged when stored, by devising the surface of the rod material when applying a ceramic coating layer or interference thin film layer. The point is to provide.

〔Constitution〕
The characteristic configuration of the invention according to claim 1 is characterized in that the surface of the bag material has a spiral uneven surface, and a plurality of undercoat coating layers are formed thereon by applying a paint, and an upper side of the plurality of undercoat coating layers. The surface of the second undercoat coating layer located on the surface and the boundary surface between the first undercoat coating layer and the second undercoat layer located on the lower side of the undercoat coating layer are flat without a spiral uneven surface. A ceramic coating layer formed on the surface of the second undercoat coating layer by applying a finishing treatment to eliminate the surface roughness, and forming a ceramic material into a film by a physical or chemical method; A fishing rod having a plurality of top coat layers formed by applying paint on the surface of the ceramic coating layer,
The operation and effect are as follows.

[Action]
That is, before applying the ceramic coating layer on the spiral irregular surface of the cocoon material, the undercoat coating layer is formed in two layers. Thereby, the spiral uneven surface can be covered with the first undercoat layer, and the boundary surface between the first undercoat layer and the second undercoat layer in the undercoat layer is formed on a flat surface having no spiral uneven surface. can do.
Then, since the second undercoat coating layer that is overlaid on the first undercoat coating layer can also be laminated on the basis of the boundary surface of the first undercoat coating layer, the thickness of the coating layer is predetermined over the entire length of the fishing rod. Can be thick.
In this way, by forming the undercoat layer into two layers, the boundary surface can be made as thin as the spiral uneven surface does not appear, and the first undercoat layer is strengthened to adhere to the second undercoat layer. It can be used as a primer.
Therefore, the second undercoat layer laminated on the first undercoat layer is treated with a predetermined thickness, and the surface thereof is a flat surface. 2 The irregular reflection of the light beam reflected at the interface with the undercoat coating layer is suppressed, and the coloring effect can be enhanced.
On the other hand, the light beam reflected from the surface of the ceramic coating layer and the surface of the second undercoat coating layer is refracted by the top coat layer portion, causing complex interference, etc. Will be presented.

〔effect〕
Therefore, compared with the case where the ceramic coating layer or the interference thin film layer is directly applied on the uneven surface, the presence of the undercoat coating layer increases the weight of the cocoon itself, but the brightness of the ceramic coating layer is increased. I was able to improve the sex.
In addition, since the ceramic coating layer on which the ceramic material is applied by a physical or chemical method is formed on the second undercoat coating layer, the ceramic coating layer is directly applied to the bag material containing reinforcing fibers. Compared with the case where the layer is formed, the reflected light rays in the second undercoat coating layer located under the ceramic coating layer become dense, and the glitter is improved.
In addition, the coating layers are arranged across multiple layers with the ceramic coating layer in between, so that it exhibits a glossy depth, but the surface may be damaged when carried or stored. We have been able to provide fishing rods that are resistant to impact and shock.

The characteristic configuration of the invention according to claim 2 is that, in the invention of claim 1 or 2, the ceramic coating layer is an interference thin film layer that develops color by utilizing interference of light, and its function and effect are It is as follows.

[Function and effect]
Since the interference thin film layer is formed as the ceramic coating layer, it is possible to expect multicolor color development due to light interference and to provide a fishing rod excellent in decorativeness.

Next, the bag A will be described.
As shown in FIG. 1, the head rod 1 as the first rod, the middle rod 2 from the second rod to the eighth rod, the former rod 3 as the ninth rod, form a collective rod A as a fishing rod To do. Here, each cage from No. 1 to No. 9 is referred to as a chassis.

A method for manufacturing each housing will be described.
First, as shown in FIG. 4, a mandrel 4 is formed by cutting a sheet-like prepreg in which a reinforcing fiber c such as carbon fiber aligned in the circumferential direction is impregnated with a thermosetting resin such as epoxy. One main pattern 5A is wound as a first layer. Thereafter, the second main pattern 5B in which the reinforcing fibers c are aligned in the axial direction, and then the third main pattern 5C in which the reinforcing fibers c are aligned in the circumferential direction are wound. The reinforcing fiber c may be glass fiber, and the resin to be impregnated may be a thermoplastic resin.

As shown in FIGS. 5 and 6, a molded tape 6 such as polyester is spirally wound around the third main pattern 5 </ b> C, and the molded product is fired in the firing furnace 3. Using a water jet device or the like, the molding tape 6 is peeled off and cut into a predetermined length to form the bag material 8. Since the saddle material 8 is in a state where the molding tape 6 is peeled off, as shown in FIG. 2, a spiral uneven surface 8 </ b> A is formed on the surface.

A plurality of coating layers are applied to the cocoon material 8 having the above-described configuration to form a skeleton body such as the tip cocoon 1. Although not shown in the figure, the painting method includes spray coating for spraying paint, handle coating for handling and applying paint, physical methods such as vacuum deposition, sputtering and ion plating, and chemical methods such as CVD. Done.

First, the tip 1 and the like will be described. As shown in FIG. 2A, an epoxy resin-based paint is applied to the spiral concavo-convex surface 8A of the saddle material 8 to form an undercoat coating layer 9 as a coating layer. A urethane resin-based paint is applied on the undercoat paint layer 9 to form an overcoat paint layer 10 as a paint layer. The undercoat coating layer 9 and the topcoat coating layer 10 are applied by spraying or a handling coating method. The coating thickness of the undercoat coating layer 9 is about 1 micron and the top coating layer 10 is about 10 microns. Here, the undercoat coating layer 9 also functions as a primer treatment agent for improving the adhesiveness of the topcoat coating layer 10.
In some cases, a clear layer may be applied to the surface of the top coat layer 10. This is for protecting the top coat layer 10.

Next, description will be made on the middle rod 2 for carrying out the present invention, and then the main rod 3 described later. As shown in FIG. 2 (b), in the middle collar 2, an epoxy resin-based paint is applied to the spiral uneven surface 8A of the collar material 8, and the first undercoat coating layer 9A of the undercoat layers. Form. An epoxy resin paint or a urethane resin paint is applied from above the first undercoat layer 9A to form a second undercoat layer 9B of the undercoat layer. The first and second undercoat coating layers 9A and 9B are applied by spraying or handling. The coating thickness of the first undercoat layer 9A may be about 1 micron, and the second undercoat layer 9B may be thicker than about 1 micron. Here, the first undercoat coating layer 9A also functions as a primer treatment agent for improving the adhesiveness of the second undercoat coating layer 9B.

It should be noted that the surface of the second undercoat coating layer 9B may be subjected to a finishing process for eliminating the surface roughness so that the reflected light from the sputtering film, which will be described later, is vivid and the glittering property is increased. This finishing process does not perform the process of grinding the spiral concavo-convex surface 8A formed by the molding tape 6 into a flat surface, but the concavo-convex surface 8A is left in a state where the spiral concavo-convex surface 8A is left. This is a smoothing process that removes fine irregularities (surface roughness) on the included surface. Further, the undercoat coating layer 9 may be only one layer.

On the second undercoat coating layer 9 </ b> B, a ceramic coating layer 11 as a coating layer or an interference thin film layer 12 having a thickness that can interfere with the ceramic coating layer 11 is formed. First, the case where the ceramic coating layer 11 is employed will be described. As shown in FIG. 2 (b), the ceramic coating film 11 is made of chromium nitride (CrN) as a ceramic material by a vapor deposition method such as vacuum vapor deposition, or a physical film forming method such as sputtering ion plating. To produce a chromium nitride (CrN) film. The chromium nitride film is formed thinner than about 1 micron. In addition to the chromium nitride film, titanium oxide (TiO2) or titanium nitride (TiN) may be used as the film formed by the physical method.
In the ceramic coating layer 11, the light reflected on the surface exhibits glitter and can be recognized by the angler as a vivid color.

The interference thin film layer 12 may be applied to the second undercoat coating layer 9B. Although not shown here, the interference thin film layer 12 is formed using a vacuum deposition method.
In other words, a holder that supports a plurality of bodies that rotate while revolving in a vacuum chamber is installed in a vertical orientation, and the ceramic deposit evaporated to the holder is guided and attached to the body. Constitute.

As an evaporation method, there are a resistance heating method, an electron gun method, a plasma method, and the like, which can be appropriately selected. The above-mentioned chromium nitride (CrN) or the like is employed as a deposit to be attached to the housing. The chromium nitride film is formed thinner than about 1 micron. Other generated films may be titanium oxide (TiO2), titanium nitride (TiN), alumina, molybdenum, or the like in addition to the chromium nitride film.

In this interference thin film layer 12, as shown in FIG. 3 (a), the interference between the light ray R1 reflected on the surface of the interference thin film layer 12 and the light ray R2 reflected on the surface of the second undercoat coating layer 9B is used. In order to generate complementary colors, it is necessary to strictly control the layer thickness, and it is desirable to suppress the thickness to 7000 angstroms or less.
In addition, as shown in FIG. 3B, the interference thin film layer 12 can be configured to overlap the upper interference thin film layer 12A and the lower interference thin film layer 12B. In this case, the lower interference thin film layer A chromium nitride (CrN) film may be provided on 12B, and a titanium oxide (TiO2) film may be provided on the upper interference thin film layer 12A. In this case, since the third light ray R3 also participates in the interference action, it is considered that a rainbow color can be seen.

As shown in FIG. 2 (b), a first top coat layer 10A is formed on the ceramic coating layer 11 (or the interference thin film layer 12), and further a second top coat layer 10B is formed on the upper side. Forming. As the first top coat layer 10A, a urethane resin coating is applied, and as the second top coat layer 10B, a urethane clear coating is applied to protect the ceramic coating layer 11 (or the interference thin film layer 12). Is going. As the second top coat layer 10B, color clear may be applied. Alternatively, the top coat layer 10 may be either the first top coat layer 10A or the second top coat layer 10B.

Thus, by providing a double protective layer on the ceramic coating layer 11 (or interference thin film layer 12), the light beam reflected from the ceramic coating layer 11 (or interference thin film layer 12) is complicated. It shows a refracted pattern and presents a tasteful decoration.

Next, the Marshal 3 etc. will be described. As shown in FIG. 2C, the first undercoat coating layer 9A constituting the undercoat coating layer is formed by applying an epoxy resin-based paint to the spiral concavo-convex surface 8A of the eaves material 8. An epoxy resin-based paint or a urethane resin-based paint is applied on the first undercoat paint layer 9A to form a second undercoat paint layer 9B constituting the undercoat paint layer. The first and second undercoat coating layers 9A and 9B are applied by spraying or a handling coating method. The coating thickness of the first undercoat layer 9A may be about 1 micron, and the second undercoat layer 9B may be thicker than about 1 micron. Here, the first undercoat coating layer 9A also functions as a primer treatment agent for improving the adhesiveness of the second undercoat coating layer 9B.
The process up to this point is the same as in the case of the middle rod 2.

Before applying the second undercoat layer 9B, the surface of the first undercoat layer 9A is ground. That is, in order to remove the influence of the spiral concavo-convex surface 8A engraved on the surface of the bag material 8, a grinding process is performed so that the concavo-convex surface 8A does not exist. Further, the surface of the second undercoat coating layer 9B is formed on a flat surface where the spiral uneven surface 8A does not exist, and a finishing process is performed to eliminate the surface roughness, and a sputtering film described later is used. To make the reflected light bright. This finishing process is a smoothing process that removes fine irregularities (surface roughness) on the flat surface.

On the second undercoat coating layer 9B, a ceramic coating layer 11 (or interference thin film layer 12) is formed in the same manner as the intermediate collar 2. Since the painting method and the like are the same as in the case of the middle collar 2, they are omitted here.

As shown in FIG. 2C, a first top coat layer 10A is formed on the ceramic coating layer 11 (or interference thin film layer 12), and a second top coat layer 10B is formed thereabove. In addition, a third top coat layer 10C is formed thereabove. As the first top coat layer 10A, a urethane resin-based clear is applied to protect the ceramic coating layer 11 (or the interference thin film layer 12). As the second top coat layer 10B, a urethane resin paint, color clear, or urethane clear paint is applied to protect the ceramic coating layer 11 (or the interference thin film layer 12). As the third top coat layer 10C, a urethane resin paint or a urethane clear coating is applied to protect the ceramic coating layer 11 (or the interference thin film layer 12).

When the first top coat layer 10A to the third top coat layer 10C are formed, since the paint is applied with a constant thickness along the axial direction of the main coat 3, the second top coat layer 10A has a second thickness. The boundary surface with the top coating layer 10B, the boundary surface with the third top coating layer 10C in the second top coating layer 10B, and the surface of the third top coating layer 10C are not affected by the spiral uneven surface 8A. It is formed on a flat surface.

Alternatively, as the topcoat layer 10, a combination of the first topcoat layer 10A and the second topcoat layer 10B or a combination of either the second topcoat layer 10B or the third topcoat layer 10C is selected. It is good also as a two-layer top coat layer. As described above, the tip rod 1 has a two-layer structure as a coating structure, the middle rod 2, the main rod 3 and the like have a five-layer structure, and the large-diameter frame has more coating layers.

May be taken. That is, when forming the first top coat layer 10A and the second top coat layer 10B, the paint is applied with a constant thickness along the axial direction of the intermediate collar 2, and the second top coat layer 10A has a second thickness. The boundary surface with the top coat layer 10B and the surface of the second top coat layer 10B may be formed as flat surfaces that are not affected by the spiral uneven surface 8A.
