Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tubular body and a method for producing the tubular body, and more particularly to a technique for forming a coating film on the outer surface of the tubular body.

[0002]

2. Description of the Related Art Taking a fishing rod, a golf club, etc. as a tubular body, there is a coating film forming technique for forming a tubular body of this kind, which has been disclosed in JP-A-3-219822. In this conventional example, the coating film is formed by applying a transparent resin containing particles that reflect light.

[0003]

Here, considering the above-mentioned conventional example, in this example, by forming the light-reflecting particles with the inner core and the outer core covering the outer surface, the depth and the solid It has a good aspect that a coating film having a feeling can be formed. The depth and the three-dimensional effect mean that an incident light ray is not simply reflected, but is reflected after being complicatedly refracted, or a slight change in the incident angle of the light ray causes a great change in the reflection direction. Is.

In consideration of depth and stereoscopic effect, this kind of phenomenon is that light rays incident on the same portion of the coating film surface are reflected in various directions as much as possible, or exhibit various light reflection characteristics. However, this depth, which leads to an increase in three-dimensional effect, in the conventional example, since particles having a fixed light reflection property are used, even if the thickness of the coating film is simply increased,
The three-dimensional effect does not significantly increase, and there is room for improvement.

Therefore, it is conceivable to mix particles having various light reflection characteristics with a resin.
It is conceivable that the distribution of particles will appear to be dense and dense, which will rather spoil the aesthetics.

An object of the present invention is to reasonably construct a tubular body having a deep outer surface and having a three-dimensional appearance and a manufacturing method thereof.

[0007]

The first feature of the present invention is as follows.
A light-transmissive first coating film containing particles having a predetermined light-reflecting property on the outer surface of a cylindrical material, and a light-transmitting second coating film containing particles having a light-reflective property different from the light-reflecting property. It is formed by coating at least two layers with a coating film, and

A second feature of the present invention is that a light-transmitting first coating film containing particles having a predetermined light reflection property is formed on the outer surface of a cylindrically shaped material, and the outer surface of this coating film is formed. Against
The point is to form a translucent second coating film containing particles having light reflection characteristics different from the above-mentioned light reflection characteristics in the state of being applied in layers, and the action and effect are as follows.

[0009]

When the above-mentioned first characteristic is constructed as shown in FIGS. 1 and 3, for example, the light ray L incident on the same portion of the coating film surface is the particles A of the second coating film 3 as shown in FIG. The light rays that have been reflected and transmitted through the second coating film 3 are then reflected by the particles A of the first coating film 2, and due to the difference in the light reflection characteristics of the respective particles A, A, Even light rays incident on the same part will be reflected in different directions, and reflected light of different hues will be obtained.Furthermore, such incident light rays will be refracted more complicatedly than before, or the light rays will be incident. A slight change in the angle causes a large change in the reflection direction.

Further, if the above-mentioned second characteristic is constituted as shown in FIGS. 2 and 3, for example, the first surface of the material 1 is
Since the coating film 2 and the second coating film 3 are formed independently, even if a relatively simple coating means such as spray coating or handling coating is adopted when forming the respective coating films 2 and 3, there is a practical problem. Since it is possible to form a coating film having a uniform thickness to the extent that there is no unevenness, the distribution of the particles A of the first coating film 2 and the particles A of the second coating film 3 does not show coarseness and fineness.

[0011]

As described above, the tubular body having a deep, three-dimensionally painted outer surface and its manufacturing method can be reasonably constructed.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a carbon fiber prepreg is wound around a mandrel and fired to coat the outer surface of a tubular material 1 formed into a loose taper shape. This material 1 is used for fishing rods,
The coating is formed by the following method so as to improve the appearance of the outer surface.

That is, as shown in FIG. 2, first, a light-transmitting first coating film 2 containing particles A having a predetermined light-reflecting characteristic is formed on the outer surface of the material 1 by means such as spray painting or hand painting. To dry. Next, as shown in FIG. 3, a second translucent coating film 3 containing particles A having a light reflection characteristic different from the above-mentioned light reflection characteristic is spray-coated on the outer surface of the coating film 2 and coated by hand. And the like to form a multi-coated state and dry.

As shown in FIG. 4, the particle A has a coating 5 of titanium dioxide or the like formed on the outer surface of a core 4 made of fine mica (mica), and the surface of the coating 5 and the coating 5 Of the coating film 5 of the particles A of the second coating film 3 as compared with the particles of the first coating film 2 by the interference of the reflected light from each of the interfaces between the core film 4 and the core 4. Differences are set in the light reflection characteristics by using different materials such as thickness and material.

The thickness of the coating 5 is 0.2 μm to 0.
The wavelength of visible light obtained by interference is 400 μm.
The area is about nm to 760 nm. Further, as the material of the coating film 5, ferric oxide, ferric tetra-trioxide, chromium oxide or the like is used, and the coating film 5 is formed as a single layer, or as shown in FIG. By appropriately setting the film thickness, the hue of the interference light appears variously, and further, in the particle A, the hue of the interference light continuously changes even with the change of the incident angle of the light ray L.

By forming the two-layer coating films 2 and 3 in this way, when the light ray L enters the tubular body, the light ray L is first generated by the particles A of the second coating film 3. The light rays L are reflected by the first coating film 2 and then reflected by the first coating film 2 even if white light is incident on the same portion. Reflected light is obtained, and even if the incident direction of the light ray L is slightly changed (including a relative change in the direction of the line of sight of the viewer), the reflected light is largely changed, and each coating film In 2 and 3, the hue also greatly changes, and the tubular body has a deep and three-dimensional effect and is excellent in aesthetics.

[Other Embodiments] In addition to the above embodiments, the present invention is
For example, the coating film can be formed by forming three or more layers, and the present invention can be applied to metal materials as well as fishing rods and golf clubs.

Further, in the present invention, it is possible to use particles having a unique reflection characteristic for light, such as scales of the sea bass, etc., and the particles can have various structures and shapes. .

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
