[First Embodiment]
A method for changing the shape or property of the decorative layer 3 of the casing 1 will be described. The structure of the casing 1 to be processed will be described.
Although not shown, a prepreg sheet is formed by impregnating a reinforced fiber such as carbon fiber or glass fiber in one direction with a thermosetting resin such as epoxy or a thermoplastic resin such as PET. . In addition, you may comprise a prepreg sheet | seat using a bulk mold method and a sheet mold method. The prepreg sheet is cut into a predetermined shape to form a main pattern. In addition, in order to reinforce the butt end or the like, a reinforcing pattern or the like having a shorter axial core length than the main pattern is wound around the heel side end or the butt end side of the main pattern.

As the main pattern, a first layer in which reinforcing fibers are aligned in the circumferential direction, a second layer in which reinforcing fibers are aligned in the axial direction, and a third layer in which reinforcing fibers are aligned in the circumferential direction are aligned. These are overlapped and wound around a mandrel, or sequentially wound around a mandrel and laminated to form a cylindrical body. The cylindrical body is fired integrally with the mandrel, and after the mandrel is decentered, it is cut into a predetermined length and subjected to a polishing treatment or the like to form the bag material 2.
The decorative layer 3 is formed on the outer surface of the cocoon material 2 by brushing or handling the paint, or using a thin film manufacturing technique such as PVD or CVD such as vacuum deposition.

〔mixture〕
Here, a configuration will be described in which the decoration layer 3 formed in two layers on the outer peripheral surface of the bag material 2 is subjected to a high energy treatment to mix the inner and outer decoration layers 3A and 3B. As shown in FIG. 2A, the decoration layer 3 is composed of an inner decoration layer 3A applied to the outer peripheral surface of the bag material 2 and an outer decoration layer 3B applied on the inner decoration layer 3A. . The inner decorative layer 3A is a coating film mainly composed of an epoxy / acrylic urethane paint, and contains a wear-resistant element such as chromium as the first substance. The outer decorative layer 3B is a coating film mainly made of UV paint, and contains a photopolymerization initiator as the second substance.

  As shown in FIG. 1, a light irradiation device 5 is used as a means for increasing energy. The light irradiation device 5 focuses on the outer peripheral surface of the light source 5A that generates ultraviolet light for processing, the optical mirror 5B that refracts the ultraviolet light from the light source 5A, and the heel material 2 that uses the refracted ultraviolet light as a target. An objective lens 5C to be combined, a moving support table 5D that reciprocates along the axis direction while rotating and supporting the eaves material 2 around its own axis X, and a film formation chamber 5E that accommodates the eaves material 2. The film forming chamber 5E includes a gas introduction port 5F for introducing an inert gas as a purge gas and a gas exhaust port 5G.

As ultraviolet rays (ultraviolet light) to be used, those having a wavelength shorter than 250 nanometers are used and obtained from a high-pressure mercury lamp or the like.
When the outer decoration layer 3B is irradiated with ultraviolet rays, the photopolymerization initiator absorbs it and changes to radicals in a high energy state. Radicals act on the monomers and oligomers contained in the UV paint to cause radical reactions. The liquid UV paint is changed to a solid by this radical reaction, but in the course of the change, the inner decorative layer 3A that has not yet been cured is entrained and cured.
Through such a process, as shown in FIG. 2B, the boundary between the inner and outer decorative layers 3A and 3B disappears, and a new modified decorative layer 3 is formed. In this case, if the inner decoration layer 3 </ b> A contains a wear-resistant metal such as Cr, the wear resistance effect of Cr can be expanded to the entire modified decoration layer 3.

(1) Thus, by adopting a curing process using UV paint, the soot material 2 is not heated during the curing process, and the curing agent used in the thermosetting resin constituting the soot material 2 is deteriorated. There is little to do.
(2) Further, it becomes possible to form the modified decorative layer 3 having high surface hardness and high wear resistance by UV curing.
(3) The embodiment in which a UV paint is used for the outer decoration layer 3B and an epoxy / acrylic urethane paint is used for the inner decoration layer 3A has been described. The decoration layer 3B may have a configuration using an epoxy / acrylic urethane paint.
(4) The inner and outer decorative layers 3A and 3B may be mixed using a laser beam in addition to the ultraviolet rays.
(5) As described above, when the inner and outer decorative layers 3A and 3B are integrated, the inner and outer decorative layers 3A and 3B are not separated at the boundary.

[Second Embodiment]
[Infusion / Diffusion]
Next, a process for injecting and diffusing high energy particles such as ions into the decoration layer 3 will be described. First, the ion implantation apparatus 4 as a means for increasing energy will be described.
As shown in FIG. 3, the ion implantation apparatus 4 is led out by an ion source 4A that supplies ions to be injected into the decoration layer 3 of the target casing 1 and an extraction power source 4B that extracts an ion flow from the ion source 4A. Mass analyzing magnet 4C for separating and selecting a desired ion flow from the selected ion flow, an acceleration power source 4D for accelerating the selected ion flow, a diffusion discharge nozzle 4E for diffusing and discharging the accelerated ions, and a target enclosure 1 and a vacuum chamber 4F.

  As shown in FIG. 3, the housing 1 is placed in a plurality of positions in the circumferential direction of the rotation support table 6 in the vertical orientation in the vacuum chamber 4 </ b> F, and revolves around the rotation center Z of the rotation support table 6. However, it rotates around the axis Y of the housing itself and receives ion implantation.

Here, the energy given to the ions is 100 kev to several Mev. The extraction voltage is 50 kv to 100 kv, and the ion beam current is several μA to several mA.
By injecting desired ions, water repellency can be imparted to the surface of the decorative layer 3. As the desired ions, silicon ions S ^{2+ and the} like are used, and the ion-implanted silicon ions S ²⁺ are combined with the hydroxyl group OH− in the urethane paint in the decoration layer 3 to make the surface of the decoration layer 3 water repellent. Silicon oxide is formed, and the decorative layer 3 is changed to a modified decorative layer.

Here, the method of implanting ions has been described. However, what is implanted may be silicon particles or the like instead of ions. As a result, the hydroxyl group OH- of silicon and the diisocyanate NCO ^{+ of the} urethane paint are combined to form a compound having high water repellency.

Although not shown, the case where the energy of ions to be implanted is set to a large energy such as several Mev when an interference thin film layer formed by PVD or CVD is formed on the surface of the decoration layer 3 will be described.
Then, ions travel in the decoration layer 3 and diffuse while repeating collisions with nuclei and the like existing in the decoration layer 3. Due to this diffusion, ions expand and opportunities for chemical reactions with other elements, bases, and the like widen, and the chemical layer expands.

  When ions with high energy reach the boundary surface between the decoration layer 3 and the cocoon material 2, the portion located near the boundary surface is activated, and the atoms in the decoration layer 3 and the atoms in the cocoon material 2 are mixed. Thus, it is considered that a mixing layer is formed between the decoration layer 3 and the heel material 2, and that the adhesion between the decoration layer 3 and the heel material 2 is improved by the formation of the mixing layer.

[Third Embodiment]
The case where the decoration layer 3 is formed and transformed using the light irradiation device 5 on the outer peripheral surface of the bag material 2 will be described.
[Phase change]
The sol-form raw material containing the urethane resin paint element of the decoration layer 3 is applied on the outer peripheral surface of the bag material 2 or the existing decoration layer 3. The coated surface is irradiated with laser light to solidify the sol-like raw material.

By adopting such a coating method, the drying process can be shortened as compared with the conventional method such as brush painting.
As the laser to be used, an excimer laser, an argon laser, a He—Ne laser or the like is used. As other light sources, discharge tubes, mercury lamps, xenon lamps and ultraviolet lamps can be used in addition to lasers.

[Powder-Layered]
As another film forming method, there is the following method. This is performed using the light irradiation device 5 shown in FIG. Raw material powder containing particles forming a urethane resin paint or the like is introduced from the gas inlet 5F together with an inert gas serving as a carrier gas. The raw material powder is guided and collided with the outer peripheral surface of the soot material 2, and the colliding part is irradiated with light to deposit the raw material powder in layers.
Thus, the defect | deletion site | part of the decoration layer 3 can be repaired by guide | inducing raw material powder to a predetermined site | part, and irradiating light and making it energize and deposit.

[Fourth Embodiment]
[Shave]
Here, the decoration layer 3 is etched using the light irradiation device 5 shown in FIG. A pulsed laser beam is used as the light source. It is desirable that the pulse width is as small as picoseconds or less. If it does so, since the heat insulation in the manufacturing process of the decoration layer 3 will become high, cooling is not required and there is little deterioration of the hardening | curing agent of the heel material 2. FIG.
A laser beam is squeezed by the objective lens 5C to irradiate the decoration layer 3, and high energy is applied to the irradiation point to remove a desired portion.
As a result, a fine uneven surface can be formed on the surface of the decorative layer 3 to exhibit an interference pattern utilizing light refraction, or a surface defect portion can be removed.

Although a laser is used here, plasma may be used instead.
The molding conditions for etching are as follows: a high frequency of 150 MHz is applied between the opposing electrodes, and the movable support table 5D supporting the above-described soot material 2 is placed in a chamber of 20 to 200 kPa at approximately atmospheric pressure. The introduced etching gas is guided between the electrodes to generate plasma, and the decorative film 3 is irradiated with the activated particles of ions and radicals in the plasma to perform the etching process.

A processing gas used for etching or the like is a mixture of an inert gas such as argon or helium and a reactive gas such as tetrafluoromethane gas. In addition, as the electric field used, a large output is required to etch the decorative layer 3, and 100 kHz to 150 MHz is adopted as the high frequency power source. The output power is desirably 50 W / cm ² or less at 1.2 W / cm ² or more. The discharge form is glow discharge.

  When a fine pattern is formed on the surface of the decoration layer 3, a mask is required regardless of whether light is used or this plasma is used, and an organic resist is used as the mask.

[Fifth Embodiment]
〔Removal〕
Here, impurities and the like contained in the decorative layer 3 are sublimated and removed. The apparatus to be used is performed using the laser apparatus 5 described above. When the decoration layer 3 is irradiated with a laser beam, the organic impurity located near the focus is activated by the laser light focused inside the decoration layer 3 and is bonded to a hydroxyl group or the like, thereby changing to a sublimation bond. The combined material leaks to the outside through the gaps in the decorative layer 3.
This removes impurities.

  Even when this impurity is a solvent used to dissolve the paint forming the decorative layer 3, the mixed solvent can be removed by irradiating the laser beam in this way.

  The present invention is not limited to the fishing rod rod 1 described above as a synthetic resin composite, but is a resin molded product used for a reel seat, a fishing line guide, a reel, or the like, or a bicycle frame, a crank arm, and a golf shaft. It is applied to resin molded products such as.
