【発明の属する技術分野】
本発明は、複合体に関する。更に詳しくは、金属とエチレン・プロピレン系共重合ゴムとを接着剤を介して積層させた複合体に関する。
【0002】
【従来の技術】
自動車ブレーキバルブ、産業機械用エアーバルブ、冷却水バルブ等には、従来から金属とエチレン・プロピレン・ジエン共重合ゴム(EPDM)とを接着剤層を介して加硫接着したものが用いられている。しかしながら、EPDMは耐熱性、耐薬品性にはすぐれているものの、分子内の二重結合の数が少なくかつ非極性であるため、金属との加硫接着が非常に難かしいという問題を有している。
【0003】
接着剤としては、多くの場合プライマーとカバーコートという2液タイプのもので、そのカバーコート用の接着剤には、ハロゲン含有タイプ-鉛化合物という組合せタイプのものが多く使用されている。このタイプの接着剤は、耐熱性でみた場合その耐熱限界は約120℃程度であり、EPDMなみの耐熱性がなく、要求されるEPDMの加硫接着剤としては満足できるものではなかった。
【0004】
また、カバーコートとしてこのタイプの接着剤を適用すると、加硫成形時に塗布した接着剤が金型に転写して、金型汚れを起し易いという問題もみられる。さらに、そこに含まれるハロゲン元素による金具あるいは相手ハウジングの錆発生という問題もみられる。
【0005】
【発明が解決しようとする課題】
本発明の目的は、金属に接着剤を介してエチレン・プロピレン系共重合ゴムを積層させた複合体であって、耐熱性、耐ブレーキ液性、防錆性などにすぐれ、自動車用ブレーキバルブ等として好適に使用し得るものを提供することにある。
【0006】
【課題を解決するための手段】
かかる本発明の目的は、マレイミド基含有シラン化合物およびトリアルコキシシラン誘導体を接着剤として金属とエチレン・プロピレン系共重合ゴムとを積層させた複合体によって達成される。
【0007】
【発明の実施の形態】
金属としては、SUS、SPCC、真ちゅう、アルミニウム等が、必要に応じて脱脂後ドライマッテ、ショットブラスト、サンドブラストあるいはリン酸亜鉛化成処理、リン酸鉄化成処理などを施した上で用いられる。また、エチレン・プロピレン系共重合ゴムとしては、EPDM以外にもエチレン・プロピレン共重合ゴム(EPM)も単体あるいはEPDMとのブレンド体として用いることができる。
【0008】
金属とエチレン・プロピレン系共重合ゴムとを接着させる接着剤の一方の成分として用いられるマレイミド基含有シラン化合物は、一般式
X-N-R-Si(OR1)3
X:-COCH=CHCO-( 環状基 )
R:-C6H4-(CH2)2 〜 10-または-(CH2)2 〜 10-
R1:低級アルキル基
で表される化合物が用いられる。
【0009】
また、接着剤の他方の成分として用いられるトリアルコキシシラン誘導体は、一般式
で表わされる化合物が用いられる。
【0010】
これらのマレイミド基含有シラン化合物およびトリアルコキシシラン誘導体は、ジメチルホルムアミド、ジオキソシクロペンタン等の溶媒と共に、次のような組成比で用いられる。
マレイミド基含有シラン化合物 5〜30重量%
トリアルコキシシラン誘導体 1〜15重量%

BACKGROUND OF THE INVENTION
The present invention relates to a composite. More specifically, the present invention relates to a composite in which a metal and an ethylene / propylene copolymer rubber are laminated via an adhesive.
[0002]
[Prior art]
For automotive brake valves, industrial machinery air valves, cooling water valves, etc., conventionally used are vulcanized and bonded metals and ethylene / propylene / diene copolymer rubber (EPDM) via an adhesive layer. . However, although EPDM is excellent in heat resistance and chemical resistance, it has a problem that vulcanization adhesion to metal is very difficult because of the small number of double bonds in the molecule and nonpolarity. ing.
[0003]
In many cases, the adhesive is a two-component type of primer and cover coat, and a combination type of halogen-containing type-lead compound is often used as the adhesive for the cover coat. This type of adhesive had a heat resistance limit of about 120 ° C. when viewed in terms of heat resistance, and had no heat resistance similar to EPDM, and was not satisfactory as the required EPDM vulcanized adhesive.
[0004]
In addition, when this type of adhesive is applied as a cover coat, there is a problem that the adhesive applied during vulcanization molding is transferred to the mold and easily causes mold contamination. Further, there is a problem that rust is generated on the metal fitting or the counterpart housing due to the halogen element contained therein.
[0005]

[0008]
The maleimide group-containing silane compound used as one component of the adhesive that bonds the metal and ethylene / propylene copolymer rubber has a general formula
XNR-Si (OR 1 ) 3
X: -COCH = CHCO- ( cyclic group )
R: -C 6 H 4 - ( CH 2) 2 ~ 10 - or - (CH 2) 2 ~ 10 -
R 1 : A compound represented by a lower alkyl group is used.
[0009]
The trialkoxysilane derivative used as the other component of the adhesive has a general formula

[0012]
Lamination of metal and ethylene / propylene copolymer rubber is performed by applying the above-mentioned adhesive to the metal by spraying, dipping, brushing, etc. After drying for about a minute, the copolymer rubber kneaded material kneaded using a roll or a closed kneader (intermix, Banbury mixer, kneader, etc.) is used as a compression molding machine, injection molding machine, injection molding machine, etc. It is performed by heating and pressing together with the adhesive-coated metal at about 150 to 230 ° C for about 0.5 to 30 minutes, and if necessary, a vulcanized rubber layer at about 100 to 200 ° C for about 0.5 to 20 hours. Secondary vulcanization is also performed.
[0013]
In the ethylene-propylene copolymer rubber to be kneaded, an organic peroxide as a cross-linking agent such as dicumyl peroxide, tertiary butyl cumyl peroxide, benzoyl peroxide, 1,3-di (tertiary butyl peroxide) is used. Oxyisopropyl) benzene, 2,5-dimethyl-2,5-di (tert-butylperoxy) hexane, 2,5-dimethyl-2,5-di (tert-butylperoxy) hexyne-3, 2,5 -Dimethyl-2,5-dibenzoylperoxyhexane, dilauroyl peroxide, n-butyl-4,4-bis (tertiary butylperoxy) valerate, etc. are blended and used.
[0014]
When an organic peroxide is used as a cross-linking agent, a polyfunctional unsaturated compound such as triallyl isocyanurate is used not only to obtain the required hardness and practical material properties, but also to obtain better adhesion. , Vulcanization accelerators such as triallyl cyanurate, N, N'-m-phenylenebismaleimide, trimethylolpropane trimethacrylate, ethylene glycol dimethacrylate, triallyl trimellitate, 1,6-hexanediol dimethacrylate It is preferable to do.

[0016]
【The invention's effect】
