Description

本発明は、特に自動車用のサスペンション等に用いられるラバーブッシュ等の防振部材として好適に用いることのできるゴム−樹脂積層構造体及びその製造方法に関する。   The present invention relates to a rubber-resin laminated structure that can be suitably used as a vibration-proof member such as a rubber bush used for automobile suspensions and the like, and a method for producing the same.

自動車分野において、操縦安定性を向上させると共に、路面からの高周波の振動を吸収し、車室内騒音を低減して乗車中の快適性を向上させるために、サスペンション等におけるピボット部に必要に応じてラバーブッシュ等の防振部材が用いられてきた。   In the automotive field, to improve steering stability, absorb high-frequency vibration from the road surface, reduce vehicle interior noise, and improve comfort while riding Vibration-proof members such as rubber bushes have been used.

このラバーブッシュは、通常、外筒体と内筒体との間にゴムを圧入又は加硫接着したものであり、自動車のサスペンション等に用いた場合、軸受け機能を有すると共に、ゴム層がサスペンション等から負荷を受けて変形するためスプリング機能、ダンパー機能も有する。更に、グリスアップや給油の必要がない上、組み立て時におけるアライメントの補正及び諸々の誤差を吸収することができるため、メンテナンスが容易であるという利点もある。   This rubber bush is usually one in which rubber is press-fitted or vulcanized and bonded between the outer cylinder and the inner cylinder, and when used in an automobile suspension or the like, it has a bearing function and the rubber layer has a suspension or the like. It also has a spring function and a damper function to deform under load. Further, there is an advantage that maintenance is easy because there is no need for grease up or refueling, and it is possible to absorb alignment correction and various errors during assembly.

従来は、ラバーブッシュを製造する際には、強度や耐久性等の観点から金属製の外筒体と内筒体を用いることが多かったが、軽量化が求められると共に、エンジニアリングプラスチック等の素材や新たな製法の開発によって樹脂の性能が向上したことにより、筒体として樹脂が用いられるようになった。   Conventionally, when manufacturing rubber bushes, metal outer cylinders and inner cylinders were often used from the viewpoint of strength, durability, etc., but weight reduction was required and materials such as engineering plastics were used. As the performance of the resin has improved due to the development of new manufacturing methods, the resin has come to be used as a cylinder.

この樹脂製筒体を用いたラバーブッシュは、一般に、樹脂とゴムのいずれか一方を金型内にセットし、他方を射出成形することにより一体化させる方法や、樹脂製の外筒体の内面に加硫接着剤を塗布し、その外筒体の内側に未加硫ゴムを充填して加硫接着する方法で製造されている。例えば、特開昭62−104717号公報(特許文献1)では、内筒が接着一体化したゴムブッシュを金型にセットして、そのゴムブッシュの外側に樹脂外筒(プラスチックロッド)を射出成形する方法が提案されている。   Rubber bushes using this resin cylinder are generally made by integrating either resin or rubber by setting one of the resin and rubber in the mold and injection molding the other, or the inner surface of the resin outer cylinder The vulcanized adhesive is applied to the inner cylinder, and the inside of the outer cylindrical body is filled with unvulcanized rubber and vulcanized and bonded. For example, in Japanese Patent Application Laid-Open No. Sho 62-104717 (Patent Document 1), a rubber bush with an inner cylinder bonded and integrated is set in a mold, and a resin outer cylinder (plastic rod) is injection-molded outside the rubber bush. A method has been proposed.

しかし、ゴムとプラスチックとの接着性は必ずしも良好ではなく、これまでもその接着性を向上させるために、両者の接着に用いる接着剤や、接着の際の前処理方法等について様々な検討がなされてきた。例えば、特開平2−84310号公報(特許文献2)には、加硫ゴムと合成樹脂の接着性の向上を目的として、加硫ゴム成形体の合成樹脂と接する面に、塩素化処理を施した後、その塩素化処理面にレゾール型フェノール樹脂とポリビニルアルコールのアルデヒド変性物との混合物を主成分とする接着剤層を形成する方法等が提案されている。   However, the adhesion between rubber and plastic is not always good, and in order to improve the adhesion, various studies have been made on the adhesive used to bond the two and the pretreatment method during bonding. I came. For example, in Japanese Patent Laid-Open No. 2-84310 (Patent Document 2), for the purpose of improving the adhesion between vulcanized rubber and synthetic resin, the surface of the vulcanized rubber molded body in contact with the synthetic resin is subjected to chlorination treatment. Then, a method of forming an adhesive layer mainly composed of a mixture of a resol type phenolic resin and a modified aldehyde of polyvinyl alcohol on its chlorinated surface has been proposed.

また、このようなラバーブッシュは、その使用用途の特質上、激しい温度変化の下で、大きな振動や荷重が長期にわたって加わる厳しい環境下に使用されるため、振動、温度変化、材料の劣化等により樹脂とゴムの界面(接着面)で剥離を起こし、ゴムが外筒体から脱離してしまう等の不都合が発生しやすい。これに対して従来は、内外両筒体をゴムで連結一体化した後の外筒体に絞り加工等を施してゴムの脱離を防止する方策が採られているが、絞り加工では十分な強度及び耐久性等が得られない場合も多く、また絞り加工による変形に、樹脂とゴムの界面が十分に追随できずに界面剥離を生じる場合もあった。
特開昭62−104717号公報 特開平2−84310号公報
In addition, these rubber bushes are used in severe environments where large vibrations and loads are applied over a long period of time under severe temperature changes due to the nature of their intended use, so vibrations, temperature changes, material deterioration, etc. Peeling occurs at the interface (adhesive surface) between the resin and rubber, and inconveniences such as rubber detaching from the outer cylinder are likely to occur. In contrast, conventionally, measures have been taken to prevent the rubber from being detached by drawing the outer cylinder after the inner and outer cylinders are connected and integrated with rubber. In many cases, strength, durability, and the like cannot be obtained, and the interface between the resin and the rubber cannot sufficiently follow the deformation due to the drawing process, and interface peeling sometimes occurs.
Japanese Patent Laid-Open No. 62-104717 JP-A-2-84310

従って、本発明は上記事情に鑑み、樹脂とゴムの界面における接着強度に優れると共に、絞り加工を施す場合などの接着界面に変形が生じる場合でも、その変形に良好に追随し得、良好な接着状態を確実に維持して、優れた耐久性が得られるラバーブッシュ等のゴム−樹脂積層構造体及びその製造方法を提供することを目的とする。   Therefore, in view of the above circumstances, the present invention is excellent in the adhesive strength at the interface between the resin and the rubber, and even when deformation occurs in the adhesive interface such as when drawing is performed, the deformation can be satisfactorily followed. An object of the present invention is to provide a rubber-resin laminated structure such as a rubber bush, which can reliably maintain the state and obtain excellent durability, and a method for producing the same.

本発明者は、上記の課題を解決するために鋭意検討した結果、樹脂製の内筒体と外筒体との間にゴムを配置固定してラバーブッシュ等のゴム−樹脂積層構造体を製造する際に、樹脂製の外筒体内面に、下塗り接着剤としてフェノール樹脂とヘキサペンタクロロジエン等のハロゲン化合物とを主成分とする接着剤を塗布し、その上に上塗り接着剤として塩化ゴムあるいはクロロスルホン化ポリエチレンを主成分とする接着剤を塗布して2層構造の接着剤層を形成し、この接着剤層上にゴムを接着固定することにより、樹脂とゴムとが強固に接着し、優れた耐久性、耐振動性、耐荷重性が得られ、更に、この積層構造体に絞り加工を施す場合にも接着界面が絞り加工による変形に良好に追随して界面剥離を生じることなく、良好な接着強度を十分に維持し得ることを見出し、本発明を完成したものである。また、本発明者は、更に検討を進めた結果、上記2層構造の接着剤層を形成する際、下塗り接着剤塗布後の外筒体に熱処理を施すことにより、該筒体内に未加硫ゴムを射出した際、上記2層構造の接着剤層が、該筒体内を流動する未加硫ゴムによりかき取られて偏在し、外筒体内面に形成された接着剤層が不均一化することを効果的に防止し得ることを見出した。これにより更に優れた接着強度や変形追随性を得ることができ、より高性能なラバーブッシュ等のゴム−樹脂積層構造体が得られることを見出した。   As a result of diligent studies to solve the above-mentioned problems, the present inventor manufactured a rubber-resin laminated structure such as a rubber bush by arranging and fixing rubber between the resin inner cylinder and the outer cylinder. In this case, an adhesive mainly composed of a phenolic resin and a halogen compound such as hexapentachlorodiene is applied as an undercoat adhesive to the inner surface of the resin outer cylinder, and a chlorinated rubber or By applying an adhesive mainly composed of chlorosulfonated polyethylene to form an adhesive layer having a two-layer structure, by adhering and fixing rubber on the adhesive layer, the resin and the rubber are firmly bonded, Excellent durability, vibration resistance, load resistance can be obtained, and even when this laminated structure is subjected to drawing processing, the adhesive interface follows the deformation due to drawing processing without causing interface peeling, Good adhesive strength enough It found that it is possible to maintain, and completed the present invention. In addition, as a result of further investigation, the present inventor, when forming the adhesive layer having the two-layer structure, heat-treats the outer cylindrical body after the undercoat adhesive is applied, thereby unvulcanized the cylindrical body. When the rubber is injected, the adhesive layer having the two-layer structure is scraped and unevenly distributed by the unvulcanized rubber flowing in the cylindrical body, and the adhesive layer formed on the inner surface of the outer cylindrical body becomes non-uniform. It has been found that this can be effectively prevented. As a result, it has been found that further excellent adhesive strength and deformation followability can be obtained, and a higher performance rubber-resin laminated structure such as a rubber bush can be obtained.

The rubber material having strength and durability is appropriately selected and is not particularly limited. Specifically, one kind selected from known rubber materials such as natural rubber, butadiene rubber, styrene / butadiene rubber, chloroprene rubber, or a mixture of two or more kinds in any ratio can be used.

図3は、図1及び図2における外筒体2とゴム層3との界面の拡大図である。本発明においては、上記樹脂製の外筒体2内面に、下塗り接着剤としてフェノール樹脂とハロゲン化合物を主成分とする接着剤を塗布して下塗り接着剤層51を形成し、この下塗り接着剤層51の上に、塩化ゴムあるいはクロロスルホン化ポリエチレンを主成分とする上塗り接着剤を塗布して上塗り接着剤層52を形成して、2層構造の接着剤層5を構成し、この接着剤層5を介して樹脂製の外筒体2とゴム層3とを強固に接着させる。   FIG. 3 is an enlarged view of the interface between the outer cylinder 2 and the rubber layer 3 in FIGS. 1 and 2. In the present invention, an undercoat adhesive layer 51 is formed by applying an adhesive mainly composed of a phenol resin and a halogen compound as an undercoat adhesive to the inner surface of the resin outer cylinder 2, and this undercoat adhesive layer 51 is formed. On top of 51, a top coat adhesive mainly composed of chlorinated rubber or chlorosulfonated polyethylene is applied to form a top coat adhesive layer 52 to form an adhesive layer 5 having a two-layer structure, and this adhesive layer The resin-made outer cylindrical body 2 and the rubber layer 3 are firmly bonded to each other through 5.

樹脂製の外筒体2内面に形成する上記下塗り接着剤層51には、フェノール樹脂とハロゲン化合物とを主成分とする接着剤を用いる。この接着剤に用いることのできるフェノール樹脂としては、特に限定されるものではなく、従来公知のものを用いることができる。
一方、ハロゲン化合物としては、ヘキサペンタクロロジエン等を好適に用いることができる。なお、上記の両成分を含む接着剤としては、市販品を用いることができ、具体的には、シクソンP−6−EF(ローム・アンド・ハース社製商品名)等が挙げられる。
An adhesive mainly composed of a phenol resin and a halogen compound is used for the undercoat adhesive layer 51 formed on the inner surface of the resin outer cylinder 2. It does not specifically limit as a phenol resin which can be used for this adhesive agent, A conventionally well-known thing can be used.
On the other hand, hexapentachlorodiene or the like can be suitably used as the halogen compound. In addition, as an adhesive agent containing both said components, a commercial item can be used, and, specifically, Sixon P-6-EF (Rohm and Haas brand name) etc. are mentioned.

次に、上記下塗り接着剤層51上に、上塗り接着剤として、塩化ゴム又はクロロスルホン化ポリエチレンを主成分とする接着剤を塗布し、上塗り接着剤層52を形成する。ここで用いられる接着剤は、市販品を用いることができ、本発明においてはシクソン520−EF(ローム・アンド・ハース社製商品名)やシクソン2000−EF(ローム・アンド・ハース社製商品名)等を好適に用いることができる。   Next, an adhesive mainly composed of chlorinated rubber or chlorosulfonated polyethylene is applied on the undercoat adhesive layer 51 as a topcoat adhesive to form the topcoat adhesive layer 52. Commercially available products can be used as the adhesive used here, and in the present invention, Sixson 520-EF (trade name, manufactured by Rohm and Haas) or Sixson 2000-EF (trade name, manufactured by Rohm and Haas). Etc.) can be preferably used.

なお、ゴム層3と内筒体4との接着は、用途によっては接着剤を用いずにゴムの加硫接着により固定することも可能であるが、通常は適宜な接着剤を用いて接着することが好ましい。接着剤として具体的には、下塗り接着剤としてケムロック205(ロード社製商品名)及びシクソンD−20−EF(ローム・アンド・ハース社製商品名)、上塗り接着剤としてケムロック6125(ロード社製商品名)、ケムロック6108(ロード社製商品名)、シクソン520−EF(ローム・アンド・ハース社製商品名)及びシクソン2000−EF(ローム・アンド・ハース社製商品名)等が挙げられる。   The adhesion between the rubber layer 3 and the inner cylindrical body 4 can be fixed by vulcanization adhesion of rubber without using an adhesive depending on the application, but is usually adhered using an appropriate adhesive. It is preferable. Specifically, as the adhesive, Chemlock 205 (trade name, manufactured by Lord) and Sixxon D-20-EF (trade name, manufactured by Rohm and Haas) are used as the undercoat adhesive, and Chemlock 6125 (manufactured by Lord) is used as the topcoat adhesive. Product name), Chemlock 6108 (trade name, manufactured by Lord), Sixson 520-EF (trade name, manufactured by Rohm and Haas) and Sixson 2000-EF (trade name, manufactured by Rohm and Haas).

本発明においては、接着剤塗布前に外筒体2内面のゴム層3との接触面を、ブラスト処理を施し粗面化することにより、接着力を更に向上させることができる。ブラスト処理に用いる砥粒は、通常のブラスト処理に用いられるものであれば特に制限はなく、具体的には、白色アルミナ、褐色アルミナ等を挙げることができ、本発明においては白色アルミナを好適に用いることができる。前記砥粒の粒径(d=50)は、通常88〜420μmであることが好ましい。420μmを超えると、粒度が粗すぎるため、上記樹脂成形体に砥粒が突き刺さり易くなり、その結果、ゴムとの接触面の表層に砥粒が残存し易くなる。また、88μm未満の場合は、粒度が細かすぎるため、所望の表面粗さRaを得られないおそれがある。また、ブラスト処理により粗面化された外筒体2内面のゴム層3との接触面の表面粗さRaは通常1〜6であることが好ましい。上記範囲を逸脱した場合には、所望する接着強度が得られないおそれがある。   In the present invention, the adhesive force can be further improved by roughening the contact surface of the inner surface of the outer cylindrical body 2 with the rubber layer 3 before applying the adhesive by blasting. The abrasive used for the blast treatment is not particularly limited as long as it is used for normal blast treatment, and specific examples include white alumina, brown alumina, etc. In the present invention, white alumina is preferred. Can be used. The grain size (d = 50) of the abrasive grains is usually preferably 88 to 420 μm. If it exceeds 420 μm, the particle size is too coarse, so that the abrasive grains are likely to pierce the resin molded body, and as a result, the abrasive grains easily remain on the surface layer of the contact surface with the rubber. Moreover, when it is less than 88 micrometers, since a particle size is too fine, there exists a possibility that desired surface roughness Ra cannot be obtained. Moreover, it is preferable that surface roughness Ra of the contact surface with the rubber layer 3 of the inner surface of the outer cylinder 2 roughened by the blast treatment is usually 1 to 6. When it deviates from the said range, there exists a possibility that desired adhesive strength may not be obtained.

また、外筒体2内面のゴム層3との接触面に下塗り接着剤を塗布した後、この外筒体2に熱処理を施すことにより、該筒体内に未加硫ゴムを射出した際、上記2層構造の接着剤層が、該筒体内を流動する未加硫ゴムによりかき取られて偏在し、外筒体内面に形成された接着剤層が不均一化することを効果的に防止し得、更に接着強度を向上させることができる。処理温度及び時間は、外筒体2を構成する樹脂が溶融、変形することなく、かつ該接着剤成分が硬化や分解等の変化を生じることのない条件が選定され、通常、樹脂成形体の形状及び大きさ、樹脂成形体を構成する樹脂成分ならびに接着剤の構成成分の種類等により適宜選定される。本発明において、処理温度は通常140〜150℃とし、処理時間は通常15〜20分間とすることが好ましい。   Further, after applying an undercoat adhesive to the contact surface of the inner surface of the outer cylinder 2 with the rubber layer 3, when the unvulcanized rubber is injected into the cylinder by applying heat treatment to the outer cylinder 2, It effectively prevents the adhesive layer of the two-layer structure from being unevenly distributed by being scraped off by the unvulcanized rubber flowing in the cylindrical body, and the adhesive layer formed on the inner surface of the outer cylindrical body becoming uneven. And the adhesive strength can be further improved. The processing temperature and time are selected so that the resin constituting the outer cylindrical body 2 is not melted and deformed, and the adhesive component does not undergo changes such as curing and decomposition. It is appropriately selected depending on the shape and size, the resin components constituting the resin molded body, the types of components of the adhesive, and the like. In the present invention, the treatment temperature is usually 140 to 150 ° C., and the treatment time is usually preferably 15 to 20 minutes.

更に、上記ゴム−樹脂積層構造体1の外筒体2の任意の箇所に絞り加工を施すことにより、樹脂とゴムの接着強度を向上させることができ、これにより長期使用に伴う材料や接着剤層等の劣化等により外筒体2からゴム層3が脱離することを効果的に防止することができる。この際、絞り率は製品仕様や外筒体2の強度等により適宜選定されるものであり、該積層構造体の外径に対し、通常2〜10%、特に2〜8%、更には2〜5%とすることが好ましい。絞り率が10%を超えると、外筒体2が破損したり、外筒体2とゴム層3との界面に剥離を生じるおそれがあり、2%未満の場合には所望の接着強度が得られないおそれがある。   Further, by applying a drawing process to an arbitrary portion of the outer cylinder 2 of the rubber-resin laminated structure 1, the adhesive strength between the resin and the rubber can be improved. It is possible to effectively prevent the rubber layer 3 from being detached from the outer cylindrical body 2 due to deterioration of the layer or the like. At this time, the drawing ratio is appropriately selected depending on the product specifications, the strength of the outer cylinder 2, and the like, and is usually 2 to 10%, particularly 2 to 8%, more preferably 2 to the outer diameter of the laminated structure. It is preferable to set it to -5%. If the squeezing ratio exceeds 10%, the outer cylinder 2 may be damaged, or the interface between the outer cylinder 2 and the rubber layer 3 may be peeled off. If it is less than 2%, the desired adhesive strength can be obtained. There is a risk of not being able to.

なお、上記構成の本発明のゴム−樹脂積層構造体を製造する際には、従来公知の製造設備、方法、条件等を採用することができる。また、該積層構造体を構成する筒体及びゴムの形状や材質等については、上記に限定されるものではなく、本発明の目的を逸脱しない範囲において、設備仕様や製品仕様等に応じて最適なものを採用すればよい。   In addition, when manufacturing the rubber-resin laminated structure of this invention of the said structure, conventionally well-known manufacturing equipment, a method, conditions, etc. are employable. Further, the shape and material of the cylindrical body and rubber constituting the laminated structure are not limited to the above, and are optimal in accordance with equipment specifications, product specifications, and the like without departing from the object of the present invention. What is necessary is just to adopt.
