Description

  The present invention relates to a constituent member constituting a fishing reel, and more particularly, to a constituent member of a fishing reel having an improved surface appearance.

  As a component of a fishing reel, a fiber-reinforced resin material is widely used because of its low specific gravity, high strength, and high rigidity. In general, such a material is formed into a predetermined shape by injection, and then subjected to cutting or the like, and finally becomes a member constituting the appearance of a fishing reel.

  By the way, when a resin containing reinforcing fibers such as carbon fibers is molded, an uneven waviness phenomenon like a wave is generated on the surface of the molded product due to the shrinkage rate of the reinforcing fibers and the resin, and in some cases The problem is that the reinforcing fibers float on the surface, the surface roughness is deteriorated, and the appearance is poor. In particular, when a glossy coating is applied to the surface of a molded product, such a swell phenomenon appears prominently, and a high-quality and useful appearance cannot be obtained.

Therefore, the surface of the molded product is roughened by buffing, shot honing, etc. to eliminate irregularities on the surface of the molded product and relief of reinforcing fibers, and then roughened (whitened and dulled) In order to recover the surface state, a patent document 1 proposes forming a two-layer coating film of a colorless transparent clear coating and a colored transparent clear coating.
No.1-40676

  However, if the swell of the molded product or the lift of the reinforcing fiber is severe, it cannot be erased by the conventional buffing or shot honing described above, so it is necessary to apply a thick coating, which causes dimensional problems and sagging of the coating. Problems occur. For this reason, in the molded product made of reinforced fiber resin, there are problems in improving the appearance while reducing the weight, improving the strength and the rigidity.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a fishing reel component that can improve the appearance while reducing the weight, improving the strength and rigidity of the fishing reel.

In order to achieve the above-described object, the constituent element of the fishing reel according to the present invention is an aromatic polyamide resin, carbon fiber having an average fiber diameter of 6.5 to 7 μm and an average fiber length of 1 to 1.5 mm. It is characterized in that a powder coating is applied by electrostatic coating on the surface of a base material having a surface resistance value of 10 ² Ω or less by blending at 40 to 45 wt%.

  When forming a component of a fishing reel with a fiber-reinforced resin material having the above-described blending ratio, uneven surface undulation occurs in the surface portion due to the shrinkage rate of the reinforcing fiber and the resin. In some cases, reinforced fibers may come out, but by applying a powder coating to the surface of such a molded article by electrostatic coating, the surface is roughened by the particles of the coating, and the undulations and reinforcing fibers generated on the surface It becomes possible to make the floating invisible in appearance.

  According to the component of the fishing reel of the present invention, a fishing reel having lightness, high strength and high rigidity can be obtained, and a high-quality appearance (paint reflection due to the influence of the rammed surface). A fishing reel with an appearance that is not useful) can be obtained.

Hereinafter, embodiments of a fishing reel according to the present invention will be described.
FIG. 1 is a view showing an example of a fishing reel according to the present invention, and is an enlarged view of the entire structure of a spinning reel and a cross-sectional structure of an outer plate (body cover) of a reel main body serving as a constituent member.

  A reel leg 1 of a spinning reel, which is a fishing reel, is integrally formed with a reel leg 1A to be mounted on a fishing rod, and a rotor 3 is rotatably provided with a fishing line guide 3a in front of it. In addition, a spool 5 that is supported so as to be able to move back and forth in synchronization with the rotational motion of the rotor 3 and on which a fishing line is wound is provided. A known power transmission mechanism is disposed in the reel body 1, and the rotor 3 is rotationally driven by rotating the handle 6 provided so as to protrude from the body cover 1 </ b> B constituting the reel body 1. The spool 5 is driven back and forth back and forth.

  As described above, the components of the fishing reel in the present invention are formed by injecting a reinforcing fiber resin in which a reinforcing fiber is impregnated with a synthetic resin, and the above-described reel leg 1A, body cover 1B, rotor 3, Constituent members such as the spool 5 are formed as molded articles made of such a reinforced fiber resin material.

  Then, a final appearance is formed by applying a powder paint by electrostatic coating on the surface of such a component. Here, as a constituent material of the reinforcing fiber resin, an aromatic polyamide-based resin and carbon fiber are used so that high strength and high rigidity can be realized. Moreover, the carbon fiber which is a reinforcement fiber is comprised by the short fiber form, and the content ratio with respect to resin is set to 40-45 wt% based on the evaluation result mentioned later. This content ratio is set in relation to the use of the electrostatic powder coating in which the present invention makes it impossible to effectively visually recognize the irregular waviness of the surface portion that is inevitably generated by molding. Yes.

  That is, the powder coating is in the form of a fine powder that is pulverized after blending a curing agent or additive in a synthetic resin (epoxy, urethane, acrylic, etc.) or pigment, uniformly heating and kneading and cooling it. By spraying this onto a charged object to be coated (the above-described constituent member), it is possible to form a coating film in which the uneven shape cannot be visually recognized. Powder coating is also environmentally friendly because it does not use solvents.

When the above-described electrostatic powder coating is applied to an object to be coated, a high-quality appearance cannot be obtained if the object to be coated is a perfect insulator, and some degree of conductivity is required. The present inventor pays attention to the fact that carbon fiber has a charging property, and the surface resistance value on the surface thereof is 10 ² Ω or less, whereby a high-grade appearance by electrostatic powder coating can be obtained. I found out. That is, it is desirable that the surface resistance value as an electrical property is 10 ² Ω or less if an uneven powder wave disappears visually and an electrostatic powder coating with improved appearance is realized. And the compounding rate of the carbon fiber for that needs 40 wt% or more. If the carbon fiber content is higher than 45 wt%, the carbon fiber floats on the surface of the molded product and the appearance of the coating deteriorates, and further, the physical properties tend to decrease in strength. Is 45 wt% or less.

Further, when considering the average fiber diameter and length of the carbon fibers, the carbon fiber diameter and the length can be further reduced in order that the carbon fiber content is 40 wt% and the surface resistance value is 10 ² Ω or less. However, if it is made too small, the fluidity becomes poor and molding becomes difficult. On the other hand, if it is too large, the adhesion with the powder coating material is deteriorated, and the surface is liable to be greatly swelled, and the appearance tends to be lowered. For this reason, about the carbon fiber mix | blended with above-described resin as a base material, an average fiber diameter is 6.5-7 micrometers and an average fiber length of 1-1.5 mm is used. In addition, a molded article made of such a base material is preferable because it can be applied without causing a large deformation even when the coating baking temperature is 200 ° C. when electrostatic coating is performed.

  Hereinafter, as a component of a fishing reel, the appearance (adhesion of paint, surface finish), physical properties (strength, rigidity), and moldability were evaluated when various combinations of the components were changed. The results are shown in the table below. In addition, evaluation here is implemented about the body cover shown in FIG. 1, and about the external appearance, the state after coating is discriminate | determined visually, About a physical-property value, a dangle piece is shape | molded in addition to a body cover, bending strength, It is determined by measuring the elastic modulus and tensile strength, and the formability is determined by measuring the material and the state after coating by measuring the dimensions of the molded product. Moreover, evaluation is performed in 3 steps ((circle), (triangle | delta), x), and (circle) is attached about the thing favorable as a product.

この表から明らかなように、芳香族ポリアミド系樹脂に対する炭素繊維を含有させた基材としての炭素繊維の含有量に関しては、４０〜４５ｗｔ％の範囲内で良好な結果になるとの評価が得られた。特に、製造コストや成形性を考慮すると、４０ｗｔ％とすることが最も好ましい。また、用いられる短繊維状の炭素繊維に関しても、平均繊維径が６．５〜７μｍで、平均繊維長１〜１．５ｍｍのものを用いた際に最も良好な結果になるとの評価が得られた。

As is apparent from this table, regarding the content of the carbon fiber as the base material containing the carbon fiber with respect to the aromatic polyamide resin, an evaluation that a good result is obtained within the range of 40 to 45 wt% is obtained. It was. In particular, considering the manufacturing cost and moldability, it is most preferable to set it to 40 wt%. In addition, the short fiber-like carbon fibers used are evaluated to have the best results when using fibers having an average fiber diameter of 6.5 to 7 μm and an average fiber length of 1 to 1.5 mm. It was.

  On the surface of the component (body cover 1B; base material) that has been subjected to electrostatic powder coating as described above, a coating film 10 made of powder coating is formed following the uneven waviness that occurs during molding by injection. However, since the surface is roughened, the appearance is such that the waviness cannot be visually recognized in a matte state. That is, since the reflection of light by the surface region is in a random state, the uneven undulations cannot be visually recognized, and the appearance can be improved. Therefore, unlike the prior art, it is not necessary to perform mechanical surface roughening after resin molding, and problems such as dimensional problems caused by thick coating and sagging of paint are solved.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously. For example, the coating material used as powder coating can be appropriately modified, and the coating method, the thickness of the coating film to be formed, and the like can be modified as appropriate. In addition to the reel body, rotor, and spool of the spinning reel described above, the fishing reel can be applied to various members such as the outer plate, frame, or lever of a dual-bearing reel. It is.
