Description

本発明は、塗装物の冷却方法、及びブレーキ用部品の製造方法に関する。   The present invention relates to a method for cooling a painted product and a method for manufacturing a brake component.

工業製品には各種の塗装が施される。特に、高温の環境下で使用される製品に対しては、耐熱性に優れる焼付け塗装等が施される。焼付け塗装を行った後は、塗装物を冷やす必要がある。例えば、特許文献１には、塗料を焼付けたブレーキパッドを冷却炉で冷やす技術が開示されている。また、特許文献２には、樹脂を焼付塗装した鋼板を水で冷やす技術が開示されている。

After baking, it is necessary to cool the paint. For example, Patent Document 1 discloses a technique for cooling a brake pad baked with a paint in a cooling furnace. Patent Document 2 discloses a technique of cooling a steel sheet on which a resin is baked and coated with water.
JP 2001-17891 A JP 2000-46079 A

熱硬化性の塗料を焼付け塗装する場合、塗装物が加熱される。このため、焼付け塗装を行った塗装物を取り扱う場合には該塗装物を冷やす必要がある。ここで、水に浸すことが好ましくない塗装物を冷やす場合には、該塗装物の表面に水を吹き付けて気化させる事により冷却する方法が採られることがある。しかし、塗装物を水で浸さないように冷やすには長い時間を要する。   When a thermosetting paint is baked and applied, the coated object is heated. For this reason, when handling a painted object that has been baked, it is necessary to cool the painted object. Here, when cooling a coated object that is not preferable to be immersed in water, a method of cooling by spraying water on the surface of the coated object and vaporizing it may be employed. However, it takes a long time to cool the paint so as not to immerse it in water.

本発明は、このような課題に鑑みてなされたものであり、焼付け塗装した塗装物に水を吹き付けて該塗装物を冷却する場合の冷却時間を短縮可能な塗装物の冷却方法、及び焼付け塗装したブレーキ用部品の冷却時間を短縮可能なブレーキ用部品の製造方法を提供することを課題とする。   The present invention has been made in view of such a problem, and a cooling method for a coated material capable of shortening the cooling time when water is sprayed on the painted material to be baked to cool the painted material, and a baked coating. It is an object of the present invention to provide a method for manufacturing a brake component capable of shortening the cooling time of the brake component.

本発明は、上記課題を解決するため、焼付け塗装を行った塗装物に水を吹き付けて冷却する際、塗装物にプラズマ処理を予め施す。   In order to solve the above-described problems, the present invention preliminarily performs plasma treatment on the coated object when water is sprayed on the painted object to be cooled.

詳細には、熱硬化性の塗料が焼付け塗装された塗装物を冷却する冷却方法であって、前記塗料が焼付け塗装された前記塗装物の表面に、該塗装物の表面と水との親和性を高める所定の表面処理を施す表面処理工程と、前記所定の表面処理が施された前記塗装物の表面に水を吹き付けて該塗装物を冷却する冷却工程と、を有する。   Specifically, it is a cooling method for cooling a paint product that has been baked and coated with a thermosetting paint, and the surface of the paint product that has been baked and coated with the paint has an affinity between the surface of the paint product and water. A surface treatment step of performing a predetermined surface treatment for increasing the temperature, and a cooling step of cooling the coated material by spraying water on the surface of the coated material subjected to the predetermined surface treatment.

焼付け塗装を経た塗装物に水を吹き付けて冷却する場合に、冷却を短時間で行うには、吹き付けた水と塗装物との間で熱交換が速やかに行われることが肝要である。ここで、熱交換の速度は、接触面の面積に比例する。このため、水を霧状に吹き付けて塗装物を冷却する場合、塗装物の表面が吹き付けた水で全面的に濡れていることが好ましい。そこで、上記冷却方法では、焼付け塗装がなされた塗装物の表面に所定の表面処理を施す。所定の表面処理とは、焼付け塗装後、水の吹き付けによる冷却の前に行う処理であり、塗装物の表面と水との親和性を高める処理である。このような表面処理を施すことにより、塗装物の表面が濡れやすくなるので、塗装物の表面に水を吹き付けた際、吹き付けた水と塗装物との間で熱交換が速やかに行われ、塗装物の冷却が短時間で行われるようになる。   In order to cool in a short time when water is sprayed on a painted object that has been baked, it is important that heat exchange be performed quickly between the sprayed water and the painted object. Here, the rate of heat exchange is proportional to the area of the contact surface. For this reason, when water is sprayed in the shape of a mist to cool the coated object, it is preferable that the surface of the coated object is completely wetted with the sprayed water. Therefore, in the cooling method described above, a predetermined surface treatment is performed on the surface of the painted object that has been baked. The predetermined surface treatment is a treatment performed after baking painting and before cooling by spraying water, and is a treatment for increasing the affinity between the surface of the coated material and water. By applying such a surface treatment, the surface of the coated object is easily wetted, so when water is sprayed on the surface of the painted object, heat exchange is quickly performed between the sprayed water and the painted object, and the coating is performed. The object is cooled in a short time.

なお、前記塗装物の表面に施す前記所定の表面処理は、プラズマ処理であることがより好ましい。塗装物にプラズマ処理を施すことにより、塗装物の表面と水との親和性が高くなるので、塗装物の表面に水を吹き付けた際に熱交換が速やかに行われ、塗装物の冷却が
短時間で行われるようになる。 In addition, it is more preferable that the predetermined surface treatment applied to the surface of the coated object is a plasma treatment. By applying plasma treatment to the painted object, the affinity between the surface of the painted object and water is increased, so heat exchange is performed quickly when water is sprayed on the surface of the painted object, and cooling of the painted object is short. To be done in time.

また、前記塗装物は、前記冷却工程では、前記塗装物の表面に吹き付けた水が前記焼付け塗装により該塗装物に残留する熱で気化するように該塗装物を冷却するものであることが好ましい。   Moreover, it is preferable that the said coating object is what cools this coating object in the said cooling process so that the water sprayed on the surface of the said coating object vaporizes with the heat which remains in this coating object by the said baking coating. .

塗装物を塗装した後に出荷する場合において、塗装物が濡れていることは好ましくない。このため、塗装物を水で冷却した場合において、この水が塗装物に付着しているときには、出荷前に水分を除去する必要がある。しかし、上記冷却方法によれば、塗装物の表面が濡れやすいため、塗装物に残留する熱で水が全て気化してしまう程度の量の水で塗装物を十分に冷却することが可能であり、水分を除去する工程を省くことができる。このような効果は、例えば、吸水性の材料、或いは水により変性し得る材料を有する塗装物を塗装する場合に顕著である。   In the case of shipping after painting a painted product, it is not preferable that the painted product is wet. For this reason, when the coated object is cooled with water and the water adheres to the coated object, it is necessary to remove moisture before shipment. However, according to the above cooling method, the surface of the coated object is easily wetted, and therefore it is possible to sufficiently cool the coated object with an amount of water that is sufficient to vaporize all the water remaining in the painted object. The step of removing moisture can be omitted. Such an effect is remarkable when, for example, a paint having a water-absorbing material or a material that can be modified by water is applied.

また、前記塗装物は、摩擦材を有するブレーキ用部品を挙げることができる。ブレーキ用の摩擦材は、水に浸すとこれを吸収してしまうため、製品としてこのまま出荷することは好ましくない。しかし、上記冷却方法によれば、このような水に浸すことができないブレーキ用部品を短時間で冷却することが可能であり、本発明の効果を有意に発揮することが可能である。   Moreover, the said coating material can mention the components for brakes which have a friction material. Since the brake friction material absorbs the friction material when immersed in water, it is not preferable to ship it as a product. However, according to the cooling method, it is possible to cool such brake parts that cannot be immersed in water in a short time, and the effects of the present invention can be exhibited significantly.

なお、本発明は、ブレーキ用部品の製造方法として捕らえることも可能である。すなわち、本発明は、摩擦材を有するブレーキ用部品を製造する製造方法であって、前記ブレーキ用部品の表面に熱硬化性の塗料を焼付け塗装する塗装工程と、前記塗料が焼付け塗装された前記ブレーキ用部品の表面に、該ブレーキ用部品の表面と水との親和性を高める所定の表面処理を施す表面処理工程と、前記所定の表面処理が施された前記ブレーキ用部品の表面に水を吹き付けて該ブレーキ用部品を冷却する冷却工程と、を有するものであってもよい。   In addition, this invention can also be caught as a manufacturing method of the components for brakes. That is, the present invention is a manufacturing method for manufacturing a brake component having a friction material, the coating step of baking a thermosetting coating on the surface of the brake component, and the coating with the coating of the coating A surface treatment step for applying a predetermined surface treatment for increasing the affinity between the surface of the brake component and water to the surface of the brake component, and water on the surface of the brake component subjected to the predetermined surface treatment A cooling step of spraying and cooling the brake parts.

焼付け塗装した塗装物に水を吹き付けて該塗装物を冷却する場合の冷却時間を短縮可能な塗装物の冷却方法、及び焼付け塗装したブレーキ用部品の冷却時間を短縮可能なブレーキ用部品の製造方法を提供することが可能になる。   Method of cooling a coated product capable of reducing the cooling time when water is sprayed on the painted product to cool the painted product, and a method of manufacturing a brake component capable of reducing the cooling time of the brake-coated component It becomes possible to provide.

以下、本願発明の一実施形態について説明する。本実施形態は、本願発明に係るブレーキ用部品の製造方法の一実施形態である。しかし、係る製造方法には、本願発明に係る塗装物の冷却方法の一実施形態が含まれている。塗装物の冷却方法に対応する部分が何れの箇所であるかについては後述する。   Hereinafter, an embodiment of the present invention will be described. This embodiment is an embodiment of a method for manufacturing a brake component according to the present invention. However, the manufacturing method includes an embodiment of the method for cooling a coated object according to the present invention. It will be described later which part corresponds to the cooling method of the coated object.

図１は、本実施形態に係るブレーキ用部品の製造方法の処理フロー図である。また、図２は、本実施形態に係るブレーキ用部品の製造工程を示す図である。以下、図１のフロー図および図２の工程図に沿って本実施形態を説明する。なお、本実施形態では、ブレーキ用部品として、摩擦材を有するブレーキパッド１を例示している。しかし、本発明に係る塗装物の冷却方法は、ディスクブレーキのブレーキパッドに限られず、例えば、焼付け塗装を施した多種多様な工業製品全般に対して適用することも可能である。   FIG. 1 is a process flow diagram of a method for manufacturing a brake component according to the present embodiment. Moreover, FIG. 2 is a figure which shows the manufacturing process of the components for brakes concerning this embodiment. Hereinafter, the present embodiment will be described with reference to the flowchart of FIG. 1 and the process diagram of FIG. In the present embodiment, the brake pad 1 having a friction material is illustrated as a brake component. However, the method for cooling a coated object according to the present invention is not limited to a brake pad of a disc brake, and can be applied to, for example, a wide variety of industrial products that have been baked.

本実施形態に係るブレーキ用部品の製造方法は、プレッシャプレートに摩擦材が固定されたブレーキパッド１（本発明でいう塗装物に相当する）に熱硬化性の粉体塗料を静電塗布したのち（Ｓ１０１）、ブレーキパッド１を加熱して塗料を焼付け（Ｓ１０２）、プラズマ処理を施し（Ｓ１０３）、水をミスト状に吹き付けてブレーキパッド１を冷却する（
Ｓ１０４）。 The brake component manufacturing method according to the present embodiment is obtained by electrostatically applying a thermosetting powder coating to a brake pad 1 (corresponding to a coated product in the present invention) in which a friction material is fixed to a pressure plate. (S101), the brake pad 1 is heated and the paint is baked (S102), plasma treatment is performed (S103), and water is sprayed in a mist shape to cool the brake pad 1 (
S104).

粉体塗料の静電塗布（Ｓ１０１）は、コロナ荷電方式により行う。すなわち、粉体塗料の静電塗布は、ブレーキパッド１を電気的に接地し、静電ガンで粉体塗料を帯電させながら、プレッシャプレート２の表面のうち特に摩擦材３が取り付けられている面と反対側の面を中心に塗料を吹き付ける（図２（Ａ）参照）。なお、粉体塗料の静電塗布は、静電ガンが設置されたハウジング内をブレーキパッド１が連続的に通過することで行われる。また、塗布される粉体塗料は、エポキシ系あるいはポリエステル系の熱硬化性樹脂で構成される塗料である。ブレーキパッド１は、粉体塗料を静電塗布する前に予めリン酸鉄処理（０．０５ＭＰａでスプレー）を行い、水洗および乾燥を施したものである。   The electrostatic coating (S101) of the powder coating is performed by a corona charging method. That is, electrostatic coating of the powder coating is performed by electrically grounding the brake pad 1 and charging the powder coating with an electrostatic gun while the surface of the pressure plate 2 on which the friction material 3 is particularly attached. The paint is sprayed around the surface on the opposite side (see FIG. 2A). The electrostatic coating of the powder coating is performed by continuously passing the brake pad 1 through the housing where the electrostatic gun is installed. The powder coating applied is a coating made of an epoxy or polyester thermosetting resin. The brake pad 1 has been subjected to iron phosphate treatment (spraying at 0.05 MPa), washing with water and drying before electrostatically applying the powder coating.

塗料の焼付け（Ｓ１０２）は、粉体塗料を静電塗布されたブレーキパッド１が電気ヒータで加熱されることにより行われる。すなわち、塗料の焼付けは、粉体塗料が電気ヒータにより１８０℃で２０分間加熱されることにより、粉体塗料が溶解してブレーキパッド１の表面に焼き付けられる。なお、粉体塗料の静電塗布（Ｓ１０１）および塗料の焼付け（Ｓ１０２）の一連の工程が、本発明でいう塗装工程に相当する。   The baking of the paint (S102) is performed by heating the brake pad 1 electrostatically coated with the powder paint with an electric heater. That is, the paint is baked on the surface of the brake pad 1 by the powder paint being heated at 180 ° C. for 20 minutes by an electric heater to dissolve the powder paint. Note that a series of steps of electrostatic coating of powder coating (S101) and baking of coating (S102) correspond to the coating step in the present invention.

プラズマ処理（Ｓ１０３）は、反応器で生成されたプラズマをブレーキパッド１に当てる事で、該ブレーキパッド１の表面を処理する。プラズマ処理の条件は、１０ｋＶの交流電圧で７０ｍＡの電気を使い、照射距離２５ｍｍで１０秒間行う（本発明でいう、表面処理工程に相当する）。プラズマを生成するためのガスとしては、例えば、アルゴンと酸素との混合ガス等が挙げられる。なお、塗料の劣化抑制や塗膜の表面改質の観点から、プラズマ処理は、大気圧による低温プラズマを用いることが好ましい。   In the plasma treatment (S103), the surface of the brake pad 1 is treated by applying the plasma generated in the reactor to the brake pad 1. The plasma treatment is performed at an irradiation distance of 25 mm for 10 seconds using an electricity of 70 mA at an AC voltage of 10 kV (corresponding to the surface treatment step in the present invention). Examples of the gas for generating plasma include a mixed gas of argon and oxygen. In addition, it is preferable to use the low temperature plasma by atmospheric pressure from a viewpoint of the deterioration suppression of a coating material, or the surface modification of a coating film.

ブレーキパッド１の冷却（Ｓ１０４）は、プラズマ処理が施されたブレーキパッド１の表面に霧状の水（ミスト）を吹き付けて行う（本発明でいう、冷却工程に相当する）。ブレーキパッド１の摩擦材が濡れるのを防ぐため、水の吹き付けは、ブレーキパッド１に吹き付けた水が気化しなくならないように短時間で行う。すなわち、ブレーキパッド１への水の吹き付けは、塗料の焼付けによりブレーキパッド１に残留している熱で水が気化するよう、短時間で行う。   The brake pad 1 is cooled (S104) by spraying mist of water (mist) on the surface of the brake pad 1 that has been subjected to the plasma treatment (corresponding to the cooling step in the present invention). In order to prevent the friction material of the brake pad 1 from getting wet, the water is sprayed in a short time so that the water sprayed on the brake pad 1 does not vaporize. That is, the spraying of water on the brake pad 1 is performed in a short time so that the water is vaporized by the heat remaining on the brake pad 1 due to the baking of the paint.

なお、上記に示した各工程のうち、プラズマ処理（Ｓ１０３）およびブレーキパッド１の冷却（Ｓ１０４）の部分が、本発明に係る塗装物の冷却方法の一実施形態に相当する部分である。粉体塗料の静電塗布（Ｓ１０１）から冷却（Ｓ１０４）までの一連の工程は、搬送装置類により連続的に処理し、人による手作業を介在させないことが冷却時間の短縮等の観点から好ましい。   In addition, among each process shown above, the part of plasma processing (S103) and the cooling (S104) of the brake pad 1 is a part corresponded to one Embodiment of the cooling method of the coating material which concerns on this invention. A series of steps from electrostatic coating (S101) to cooling (S104) of the powder coating is preferably processed continuously by a conveying device, and from the viewpoint of shortening the cooling time, etc. without manual human intervention. .

本実施形態によれば、次のような理由により、ブレーキパッド１を冷却する場合の冷却時間を短縮可能である。図３は、ブレーキパッド１の表面に付着した水の付着状態について、プラズマ処理を施していないものとプラズマ処理を施したものとを並べて示した図である。ブレーキパッド１の表面にプラズマ処理を施すと、水との親和性が高まる。よって、図３に示すように、プラズマ処理を施していない場合、ブレーキパッド１に吹き付けた水は接触角が約９０度と垂直に近い水玉状態になる一方、プラズマ処理を施した場合、ブレーキパッド１に吹き付けた水は接触角が小さくなって表面に大きく広がる。従って、冷却（Ｓ１０４）の際に吹き付ける水が少なくてもブレーキパッド１の表面が非常に濡れやすく、ブレーキパッド１に残留する熱が水に奪われやすくなるので、プラズマ処理を施さない場合に比べて短い時間でブレーキパッド１を冷却することが可能になる。   According to this embodiment, the cooling time when cooling the brake pad 1 can be shortened for the following reasons. FIG. 3 is a diagram showing the state of the water adhering to the surface of the brake pad 1 that is not subjected to the plasma treatment and that subjected to the plasma treatment side by side. When plasma treatment is performed on the surface of the brake pad 1, the affinity with water increases. Therefore, as shown in FIG. 3, when the plasma treatment is not performed, the water sprayed on the brake pad 1 is in a polka dot state where the contact angle is approximately 90 degrees, and when the plasma treatment is performed, The water sprayed on 1 has a small contact angle and spreads widely on the surface. Therefore, even if the amount of water sprayed at the time of cooling (S104) is small, the surface of the brake pad 1 is very wet and the heat remaining on the brake pad 1 is easily taken away by the water. Thus, the brake pad 1 can be cooled in a short time.

以下、上記実施形態に係る製造方法の評価結果について説明する。以下に示す評価結果において、「実施例」として示すものが上記実施形態に係る製造方法に関するものであり
、「比較例」として示すものがプラズマ処理のみを省いたものである。なお、冷却処理（Ｓ１０４）で水を噴霧した時間（ミストスプレー時間：Ｔ１）については、下記に示す表１の通り、６０秒と１８０秒の２種類の条件で実験を行った。また、プラズマ処理（Ｓ１０３）を施してから冷却処理（Ｓ１０４）を開始するまでの時間（Ｔ２）については、下記に示す表１の通り、２０秒、３０秒、６０秒、１２０秒の４種類の条件で実験を行った。なお、比較例については、プラズマ処理を施していないため、下記に示す表１の通り、プラズマ処理（Ｓ１０３）を施してから冷却処理（Ｓ１０４）を開始するまでの時間（Ｔ２）についてはその記載を省いている。

Figure 2010125407
Hereinafter, the evaluation result of the manufacturing method according to the embodiment will be described. In the evaluation results shown below, what is shown as “Example” relates to the manufacturing method according to the above embodiment, and what is shown as “Comparative Example” excludes only the plasma treatment. In addition, about time (mist spray time: T1) which sprayed water by cooling process (S104), as shown in Table 1 below, it experimented on two types of conditions, 60 seconds and 180 seconds. Moreover, as for the time (T2) from the plasma treatment (S103) to the start of the cooling treatment (S104), four types of 20 seconds, 30 seconds, 60 seconds, and 120 seconds are shown in Table 1 below. The experiment was conducted under the following conditions. In addition, since the plasma processing is not performed for the comparative example, as described in Table 1 below, the time (T2) from when the plasma processing (S103) is performed to when the cooling processing (S104) is started is described. Is omitted.
Figure 2010125407

上記表１に示すように、プラズマ処理を施してから冷却を行った実施例１〜８は、プラズマ処理を施さないで冷却を行った比較例１，２に比べ、表面温度が著しく低下していることが判る。特に、水の吹き付けを１８０秒間も行った比較例２よりも、水の吹き付けを６０秒間しか行っていない実施例１〜４の方が、表面温度が低い。よって、プラズマ処理を経てから水を吹き付けると、極めて効率的に冷却されることが判る。従って、焼付け塗装した塗装物を冷却する場合に、上記実施形態に係る方法を適用すれば、冷却時間を極めて短縮できることが判る。なお、プラズマ処理による効果は、時間の経過と共に低下する。上記表１に示すように、プラズマ処理を行った後、冷却処理を開始するまでの時間（Ｔ２）が長くなればなるほど、冷却処理を施した後の表面温度が下がりにくくなっている。よって、ブレーキパッド１を例えば７０〜８０℃程度にしたいような場合、プラズマ処理を施した後、冷却処理を開始するまでの時間（Ｔ２）を６０秒以内にすることが好ましく、特に、３０秒以内とすることがより好ましい。プラズマ処理を施した後、冷却処理を開始するまでの時間（Ｔ２）を短くすることで、プラズマ処理を施すことによる冷却時間の短縮化をより効果的に実現できる。   As shown in Table 1, in Examples 1 to 8, which were cooled after being subjected to plasma treatment, the surface temperature was remarkably reduced compared to Comparative Examples 1 and 2 which were cooled without being subjected to plasma treatment. I know that. In particular, the surface temperatures of Examples 1 to 4 in which water is sprayed for only 60 seconds are lower than those in Comparative Example 2 in which water is sprayed for 180 seconds. Therefore, it can be seen that when water is sprayed after the plasma treatment, cooling is extremely efficient. Therefore, it can be seen that the cooling time can be greatly shortened by applying the method according to the above-described embodiment when cooling the baked paint. Note that the effect of the plasma treatment decreases with time. As shown in Table 1, the surface temperature after the cooling treatment is less likely to decrease as the time (T2) until the cooling treatment starts after the plasma treatment is increased. Therefore, when it is desired to set the brake pad 1 to about 70 to 80 ° C., for example, the time (T2) until the cooling process is started after the plasma process is preferably within 60 seconds, particularly 30 seconds. It is more preferable to be within the range. By shortening the time (T2) until the cooling process is started after the plasma process is performed, the cooling time can be shortened more effectively by performing the plasma process.
