Description

【0001】
【発明の属する技術分野】
本発明は、銅、鉄鋼、およびアルミニウム等の金属またはガラス繊維、シリカ、酸化アルミニウム、水酸化アルミニウム等の無機物質と樹脂との接着性の改善を行うための表面処理剤、または、エポキシ樹脂等の樹脂の機械的強度の改善を行うための樹脂添加剤およびそれらに有用な有機ケイ素化合物に関する。
【0002】
【従来の技術】
電子機器のボードは銅箔と紙−フェノール樹脂含浸基材やガラス−エポキシ樹脂含浸基材等を加熱、加圧して銅張積層板を作製した後、エッチングして回路網を形成し、これに半導体装置等の素子を搭載することにより作られる。
【0003】
これらの過程では、銅箔と基材との接着、加熱、酸やアルカリ液への浸漬、レジストインクの塗布、ハンダ付け等が行われるため、さまざまな性能が要求される。これらの要求を満たすために、銅箔は黄銅層形成処理(特公昭51−35711号公報、同54−6701号公報)やクロメート処理、亜鉛または酸化亜鉛とクロム酸化物とからなる亜鉛−クロム基混合物被覆処理(特公昭58−7077号公報)、シランカップリング剤処理等が検討されている。また、樹脂は樹脂や硬化剤の種類およびその配合量を変えたり、添加剤等によって上記要求特性を満足させている。また、ガラス繊維はシランカップリング剤等の表面処理等が検討されている。しかしながら、最近、プリント回路が緻密化しているので、使用される電子機器用のボードに要求される特性はますます厳しくなっている。
【0004】
これに伴うエッチング精度の向上に対応するため銅箔のプリプレグと接着される粗化面(M面)にはさらに低い表面粗さ(ロープロファイル)も求められている。しかし、M面の表面粗さは一方ではプリプレグとの接着にあたって、アンカー効果をもたらしているので、M面に対するこのロープロファイルの要求と接着力の向上とは二律背反の関係にあり、ロープロファイル化によるアンカー効果の低減分は別の手段による接着力の向上で補償することが必要である。
【0005】
また、発電所などの高電圧・高容量の機器や半導体の封止等に使われている電気絶縁用注型材料はエポキシ樹脂のマトリックス中にシリカやアルミナ等の無機物質を充填した複合材料である。これらの材料には様々な電気的・機械的特性が要求されており、それらの特性を満足させるためには、無機物質と樹脂の接着性を向上させる必要がある。この対策としてシランカップリング剤を樹脂中に添加したり、無機物質をシランカップリング剤で表面処理することが提案されているが、さらなる樹脂/無機物質界面の改善が要求されている。
【0006】
【発明が解決しようとする課題】
本発明は、こうした要請に対応できる、すなわち銅、鉄鋼およびアルミニウム等の金属またはガラス繊維、シリカ、酸化アルミニウム、水酸化アルミニウム等の無機物質と樹脂との接着性を向上させることができる新規な有機ケイ素化合物、その製造方法、並びにそれを用いた表面処理剤または樹脂添加剤を提供することを目的とするものである。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a surface treatment agent for improving the adhesion between a resin such as copper, steel, aluminum or another metal or glass fiber, silica, aluminum oxide, or an inorganic material such as aluminum hydroxide, or an epoxy resin. The present invention relates to a resin additive for improving the mechanical strength of the resin and an organosilicon compound useful therefor.
[0002]
[Prior art]
The board of electronic equipment is made by heating and pressing copper foil and paper-phenol resin impregnated base material or glass-epoxy resin impregnated base material to produce a copper-clad laminate, then etching to form a circuit network, It is made by mounting elements such as semiconductor devices.
[0003]
In these processes, various performances are required because bonding between the copper foil and the base material, heating, immersion in an acid or alkali solution, application of a resist ink, soldering, and the like are performed. In order to satisfy these requirements, the copper foil is subjected to a brass layer forming treatment (JP-B-51-35711 and JP-B-54-6701), a chromate treatment, and a zinc-chromium group comprising zinc or zinc oxide and chromium oxide. A mixture coating treatment (Japanese Patent Publication No. 58-7077), a silane coupling agent treatment, and the like have been studied. Further, the resin satisfies the above-mentioned required characteristics by changing the kind of the resin and the curing agent and the amount thereof, and by adding additives. Surface treatment of glass fibers with a silane coupling agent or the like is being studied. However, recently, as printed circuits are becoming more and more compact, characteristics required for boards for electronic devices to be used are becoming increasingly severe.
[0004]
In order to cope with the improvement in etching accuracy accompanying this, a further lower surface roughness (low profile) is required on a roughened surface (M surface) bonded to a prepreg of copper foil. However, on the other hand, the surface roughness of the M surface has an anchor effect in bonding with the prepreg, so that the requirement of the low profile for the M surface and the improvement of the adhesive force are in a trade-off relationship, and the low profile It is necessary to compensate for the reduction in the anchor effect by improving the adhesive force by another means.
[0005]

These materials are required to have various electrical and mechanical properties, and in order to satisfy those properties, it is necessary to improve the adhesion between the inorganic substance and the resin. As measures against this, it has been proposed to add a silane coupling agent to the resin or to perform a surface treatment of an inorganic substance with the silane coupling agent, but further improvement of the resin / inorganic substance interface is required.

Evaluation 5: No discoloration 4; Slight discoloration 3; Slight discoloration 2; Discoloration to orange or yellow 1; Discoloration to black brown
Example 5 (Application as an additive to resin)
Two untreated aluminum alloy plates were obtained in Example 1 with an epoxy resin composition (Epicoat 828: 100 parts by weight, dicyandiamide (manufactured by Kanto Chemical): 5 parts by weight, 2-ethyl-4-methylimidazole 1 part by weight). (A novel organosilicon compound: 1 part by weight) was adhered under curing conditions of 100 ° C. for 1 hour and 150 ° C. for 1 hour, and a tensile shear adhesion test was performed according to JIS K6850. Table 3 shows the results.
[0034]
Comparative Example 4
An aluminum alloy plate was similarly adhered using 1 part by weight of 3-glycidoxypropyltrimethoxysilane instead of the novel organosilicon compound of Example 5, and evaluated. Table 3 shows the results.
