Abstract

PURPOSE:To provide the surface layer structure of a member readily giving a sufficiently deep or stereoscopic appearance by forming a phototransmissive transparent protective layer or the outside of a phototransmissive resin layer mixed with light-reflective particles and formed or the main body of the member. CONSTITUTION:A phototransmissive transparent resin layer 15 mixed with light-reflecting particles 13 is formed on the main body 11 of a member prepared by winding a prepreg comprising a synthetic resin and high strength fibers impregnated with the synthetic resin. The high strength fibers include carbon fibers and aramide fibers, and the synthetic resin includes an epoxy resin and a polyester resin. A phototransmissive transparent protecting layer 17 is formed outside the above-mentioned transparent resin layer 15 to prepare the surface layer structure of the member. The surface layer structure readily gives a deep or sufficiently stereoscopic appearance because light irradiated from outside travels to the transparent resin layer through the transparent protecting layer, collides with the light-reflective particles, is reflected and reaches the sections of human eyes through the transparent protecting layer.

In the method for manufacturing the surface layer structure of a member according to claim 4, when the surface of the transparent resin layer is polished, the surface side portion of the light reflecting particles located on the surface is reliably scraped off.

[Example] Hereinafter, the details of the present invention will be explained with reference to the drawings.

FIG. 1 shows the details of the surface structure of the tubular body shown in FIG. 2, and FIG.
For example, a tubular body such as a fishing rod or a golf shaft is shown.

In FIG. 2, reference numeral 11 indicates a tubular member body.

The member main body 11 is formed by wrapping prepreg, which is a high-strength fiber impregnated with a synthetic resin.

Note that the high-strength fibers here include, for example, carbon fibers,
Fibers such as aramid fibers and glass fibers are used, and resins such as epoxy resins and polyester resins are used as the synthetic resin.

In this embodiment, as shown in FIG. 1, a transparent resin layer 15 having light-transmitting properties and containing light-reflecting particles 13 is formed on the main body 11 of the member.

A transparent protective layer 17 having light-transmitting properties is formed on the outside of the transparent resin layer 15.

FIG. 3 shows light reflecting particles 1 mixed in a transparent resin layer 15.
3, the light reflecting particles 13 are formed from an inner core 19 having translucency and an outer shell 21 formed outside the inner core 19 and made of a material with high light reflectance. .

Note that the outer diameter of the light reflecting particles 13 is, for example, 50 to 50.
The inner core 19 is made of translucent glass, resin, or the like.

Further, the outer shell 21 is formed by coating the inner core 19 with a metal such as gold, silver, or nickel by, for example, electroless plating.

As such light reflecting particles 13, for example, "Metal Coated Glass Flake (trade name)" manufactured by Nippon Sheet Glass Co., Ltd. is known.

The light reflecting particles 13 preferably have as high a light reflectance as possible, but any particles may be used as long as they can sufficiently improve the depth or three-dimensional effect.

The surface layer structure of the member configured as above is, for example,
It is manufactured by the method for manufacturing the surface layer structure of a member as described below.

That is, first, a prepreg sheet made of high-strength fiber impregnated with synthetic resin is wound around a core metal, followed by taping, heat curing, and
The tubular member body 1 is formed through a known process such as peeling off the core metal tape.
1 is formed.

After this, the outer periphery of the member main body 11 is polished.

Thereafter, a transparent paint mixed with light reflecting particles 13 having a high light reflectance is applied to the polished surface of the member main body 11, thereby forming a transparent resin layer 15.

Here, the transparent paint is made by mixing, for example, 30% by volume of the light reflecting particles 13 into a base material made of, for example, urethane.
For example, a mixture of isocyanate curing agents in a ratio of 2:1 is used.

Further, the transparent paint is applied by, for example, gun-blow (spray) painting. For example, when the light reflecting particles 13 are glass flakes with a particle size of 50 to 100 micrometers, the transparent paint is diluted to 40% with thinner. It will be held in

Incidentally, gun blowing is most suitable for uniformly dispersing the light reflecting particles 13, but brush painting, hand painting, etc. may also be used.

After this, natural drying was performed for 60 minutes, and
Forced drying is carried out for 2 hours at a temperature of 100°C.

Thereafter, the surface of the cured transparent resin layer 15 is polished using, for example, a sander, and the light reflecting particles 13 on the surface side are shaved off by this polishing.

After that, on the outside of the polished transparent resin layer 15,
A transparent protective layer 17 coated with paint such as epoxy or urethane
is formed.

Therefore, in the surface layer structure configured as described above, a transparent resin layer 15 having light-transmitting properties in which light-reflecting particles 13 are mixed is formed on the member body 11, and the outside of this transparent resin layer 15 is Since the transparent protective layer 17 having light-transmitting properties is formed, light from the outside passes through the transparent protective layer 17, advances into the transparent resin layer 15, collides with the light-reflecting particles 13, and is reflected. Since it passes through the transparent protective layer 17 and reaches the retina of the human eye, it is possible to easily obtain an appearance with sufficient depth or three-dimensional effect, and products with excellent design effects can be easily provided.

In addition, since the transparent resin layer 15 was covered with the transparent protective layer 17,
It becomes possible to reliably prevent color change, swelling, etc. of the transparent resin layer 15, and furthermore, the transparent resin layer 15 is relatively thin, and the light reflecting particles 13 are integrally formed with the transparent resin layer 15. Therefore, the rigidity, strength, etc. of the member main body 11 are not adversely affected.

In addition, in the surface layer structure of the member configured as above,
The light reflecting particles 13 are composed of an inner core 19 having translucency and an outer shell 21 formed outside the inner core 19 for reflecting light.
When the surface of the transparent resin layer 15 is polished or the like, the surface side portion of the light-reflecting particles 13 located on the surface is scraped off, and the light from the transparent protective layer 17 is reflected by the arrow A in FIG. As shown in FIG. 2, the light advances to the inner core 19 of the light reflecting particles 13 and is also reflected on the inner circumferential surface of the outer shell 21.
Even if the transparent resin layer 15 is thin, it is possible to obtain an appearance with more depth or three-dimensionality.

Furthermore, even if the outer shell 21 of the light-reflecting particles 13 is made of metal or the like, the weight of the light-reflecting particles 13 can be reduced by forming the inner core 19 of glass or the like.

In the method for manufacturing the surface layer structure of the member described above,
The manufacturing process includes a step of applying a transparent paint mixed with light reflecting particles 13 to the member body 11 to form a transparent resin layer 15, a step of polishing the surface of the transparent resin layer 15, and a step of polishing the polished transparent resin. Since the method is comprised of the steps of applying a transparent paint to the layer 15 and forming the transparent protective layer 17, when the surface of the transparent resin layer 150 is polished, the surface side portion of the light reflecting particles 13 located on the surface is surely scraped off. Therefore, it becomes possible to easily obtain a surface layer structure in which the light reflecting particles 13 located on the surface side of the transparent resin layer 15 are shaved off.

FIG. 4 shows another embodiment of the surface layer structure of the member of the present invention. In this embodiment, the outer shell 21 of the light reflecting particles 13 is disposed between the member body 11 and the transparent resin layer 15. A light-reflecting layer 23 having substantially the same color is formed.

This light reflecting layer 23 is made by applying transparent paint to the member body 11,
Although it is applied by brushing or spraying with a gun, it may also be formed by integrally attaching a resin film or the like to the member main body 11.

With the surface layer structure of the member configured as described above, it is possible to obtain almost the same effect as the embodiment shown in FIG. Since the light reflecting layer 23 having substantially the same color as the outer shell 21 of the light reflecting particles 13 is formed, the light passing between the light reflecting particles 13 of the transparent resin layer 15 is reflected by the light reflecting layer 23. Therefore, the transparent resin layer 15 is made thinner, and the member body 11 is made thinner.
Even if the light-reflecting particles I3 of the transparent resin layer 15 do not completely hide the light-reflecting particles I3, a sufficient depth or three-dimensional effect can be obtained by the reflection from the light-reflecting layer 23 and the light-reflecting particles 13, and the transparent It becomes possible to make the resin layer 15 extremely thin.

In addition, in the embodiment described above, an example was described in which the present invention was applied to a tubular member main body 11 such as a fishing rod or a shaft of a golf club, but the present invention is not limited to such an embodiment, and for example, The present invention may be applied to a planar member main body, or, for example, the present invention may be applied to the surface of a member main body made of plate material and fixed to the outer wall or inner wall of a building to improve the aesthetic appearance of the building. Of course, it is fine to do so.

That is, the present invention can be very widely applied to various members that require improved aesthetic appearance.

〔Effect of the invention〕

As described above, in the surface layer structure of claim 1, a transparent resin layer with light-transmitting properties mixed with light-reflecting particles is formed on the main body of the member, and a transparent resin layer with light-transmitting properties mixed with light-reflecting particles is formed on the outside of this transparent resin layer. Since we have formed a transparent protective layer with Since it reaches the retina of the eye, it is possible to easily obtain an appearance with sufficient depth or three-dimensionality.

In the surface layer structure of the member according to claim 2, in claim 1,
Since the light-reflecting particles are composed of a translucent inner core and an outer shell formed outside the inner core to reflect light, when the surface of the transparent resin layer is polished, etc., the light located on the surface is The surface side of the reflective particles is scraped off, and the light from the transparent protective layer travels to the inner core of the light reflective particles and is also reflected on the inner peripheral surface of the outer shell, giving it a deeper or three-dimensional effect. It becomes possible to obtain the appearance.

Furthermore, even if the outer shell of the light-reflecting particles is made of metal or the like,
By forming the inner core from glass or the like, the weight of the light reflecting particles can be reduced.

In the surface layer structure of the member according to claim 3, in claim 1 or 2, a light reflecting layer having substantially the same color as the outer shell of the light reflecting particles is formed between the main body of the member and the transparent resin layer. The light that is not reflected by the light-reflecting particles in the layer will be reflected by the light-reflecting layer, so there is no need to make the transparent resin layer thinner and completely cover the main body of the member with the light-reflecting particles in the transparent resin layer. ,
By reflection from the light reflection layer and reflection from the light reflection particles,
Sufficient depth or three-dimensionality can be obtained, and the transparent resin layer can be made extremely thin.

In the method for manufacturing a surface layer structure of a member according to claim 4, the manufacturing process includes a step of applying a transparent paint mixed with light-reflecting particles to the member body to form a transparent resin layer, and a step of forming a transparent resin layer on the surface of the transparent resin layer. It consists of a polishing process and a process of applying a transparent paint to the polished transparent resin layer to form a transparent protective layer.
When the surface of the transparent resin layer is polished, the surface side of the light-reflecting particles located on the surface will be surely scraped off.
There is an advantage that a surface layer structure in which the light-reflecting particles located on the surface side of the transparent resin layer are shaved can be easily obtained.
