Description
本発明は、ポリイミド樹脂組成物、及びそれを含むポリイミド系複合フィルムに関する。 The present invention relates to a polyimide resin composition and a polyimide composite film including the same.
近年、ガラス基板に変わりプラスチックフィルムを基板とした各種フレキシブルデバイスの研究が盛んに行われている。例えば、フレキシブル有機ELディスプレイ、フィルム型太陽電池、電子ペーパー等が挙げられる。これらのプラスチックフィルムには、デバイスの製造プロセス上、高度な耐熱性と透明性、寸法安定性が求められている。 In recent years, various flexible devices using a plastic film as a substrate instead of a glass substrate have been actively studied. For example, a flexible organic EL display, a film type solar cell, electronic paper, etc. are mentioned. These plastic films are required to have high heat resistance, transparency and dimensional stability in the device manufacturing process.
機械的強度の向上、熱膨張率の低下、ガスバリア性の向上等を目的として、各種有機樹脂と無機層状化合物との複合化が盛んに研究されており、ポリイミドについても多くの報告がある。
特許文献1には、有機オニウムイオンで有機化された層状粘土鉱物とポリイミドからなるポリイミド複合材料及びその製造方法が開示されている。
特許文献2には、有機オニウムイオンによりイオン交換能対比50〜100%イオン交換され、比表面積が特定範囲に調整された層状珪酸塩が開示されている。
特許文献3には、樹脂に層状珪酸塩を添加することにより、寸法安定性を向上させる技術が開示されている。
特許文献4には、有機化層状珪酸塩の有機化処理を工夫することにより、その分散性を向上させ、有機化層状珪酸塩を配合した場合でも良好な光学特性を有するフィルムを得る技術が開示されている。
For the purpose of improving the mechanical strength, lowering the coefficient of thermal expansion, improving the gas barrier property, etc., compounding of various organic resins and inorganic layered compounds has been actively studied, and there are many reports on polyimide.
Patent Document 1 discloses a polyimide composite material composed of a layered clay mineral and polyimide that has been organized with organic onium ions, and a method for producing the same.
Patent Document 2 discloses a layered silicate that is ion-exchanged with an organic onium ion by 50 to 100% relative to the ion exchange capacity and has a specific surface area adjusted to a specific range.
Patent Document 3 discloses a technique for improving dimensional stability by adding a layered silicate to a resin.
Patent Document 4 discloses a technique for improving the dispersibility by devising the organic treatment of the organic layered silicate and obtaining a film having good optical characteristics even when the organic layered silicate is blended. Has been.
しかしながら、特許文献1〜4に開示されたポリイミド系複合材料又はフィルムは、透明性、寸法安定性、及び水蒸気バリア性のバランスの観点から、未だ改良の余地がある。
また、層状珪酸塩を無色透明なポリイミドに多量に添加すると、寸法安定性は向上するが、層状珪酸塩同士の凝集が起こり易くなり、透明性が悪化するという問題がある。
However, the polyimide composite materials or films disclosed in Patent Documents 1 to 4 still have room for improvement from the viewpoint of the balance of transparency, dimensional stability, and water vapor barrier properties.
In addition, when a large amount of layered silicate is added to a colorless and transparent polyimide, the dimensional stability is improved, but aggregation of the layered silicate easily occurs, and there is a problem that the transparency is deteriorated.
上記事情に鑑み、本発明は、透明性、寸法安定性、及び水蒸気バリア性のバランスに優れたポリイミド樹脂組成物、及びそれを含むポリイミド系複合フィルムを提供することを目的とする。
さらには、優れた寸法安定性と透明性を両立するポリイミド樹脂組成物、及びそれを含むポリイミド系複合フィルムを提供することを目的とする。
In view of the above circumstances, an object of the present invention is to provide a polyimide resin composition excellent in the balance of transparency, dimensional stability, and water vapor barrier properties, and a polyimide-based composite film including the same.
Furthermore, it aims at providing the polyimide resin composition which balances the outstanding dimensional stability and transparency, and the polyimide-type composite film containing the same.
本発明者は上記課題を解決するために鋭意検討した結果、ポリイミドと、有機化層状珪酸塩、を含むポリイミド樹脂組成物であって、前記ポリイミド(A)中に前記有機化層状珪酸塩(B)を分散させ、さらに、前記ポリイミド(A)対する前記有機化層状珪酸塩(B)の含有量を特定範囲に調整することにより、透明性、寸法安定性、及び水蒸気バリア性のバランスに優れたポリイミド樹脂組成物、及びポリイミド系複合フィルムが得られることを見出した。
また、有機化層状珪酸塩をシランカップリング剤で処理することにより、樹脂中に有機層状珪酸塩を多量に配合した場合でも層状珪酸塩同士の凝集を抑制することができることを発見し、その結果、優れた寸法安定性と透明性を両立するポリイミド樹脂組成物、及びポリイミド系複合フィルムが得られることを見出し、本発明を完成させた。
As a result of intensive studies in order to solve the above problems, the present inventor is a polyimide resin composition containing polyimide and an organically modified layered silicate, wherein the organicated layered silicate (B) is contained in the polyimide (A). ), And further, the content of the organically modified layered silicate (B) with respect to the polyimide (A) is adjusted to a specific range, thereby providing excellent balance of transparency, dimensional stability, and water vapor barrier properties. It discovered that a polyimide resin composition and a polyimide-type composite film were obtained.
In addition, by treating the organic layered silicate with a silane coupling agent, it was discovered that even when a large amount of the organic layered silicate is blended in the resin, aggregation of the layered silicates can be suppressed. The present inventors have found that a polyimide resin composition and a polyimide-based composite film having both excellent dimensional stability and transparency can be obtained, and the present invention has been completed.

また、本実施形態の樹脂組成物をフィルムとして用いる場合、交換性陽イオンに対する有機オニウムイオンの置換率が50ミリグラム当量/100g未満であると、有機化層状珪酸塩の分散性が低下し、有機化層状珪酸塩の凝集体の影響でフィルムの光学特性が低下するおそれがある。一方、90ミリグラム当量/100gを超えると、樹脂組成物をフィルム状にした後、加熱により溶媒を除去する乾燥工程において、有機オニウムイオンの熱分解が起こりやすくなり、光学特性の悪化を招くおそれがある。 Further, when the resin composition of the present embodiment is used as a film, the dispersibility of the organically modified layered silicate is reduced when the substitution rate of the organic onium ion with respect to the exchangeable cation is less than 50 milligram equivalent / 100 g. There is a possibility that the optical properties of the film may deteriorate due to the influence of the aggregate of the layered silicate. On the other hand, if it exceeds 90 milligram equivalent / 100 g, after the resin composition is made into a film, the organic onium ions are likely to be thermally decomposed in the drying step of removing the solvent by heating, which may lead to deterioration of optical properties. is there.
交換性陽イオンに対する有機オニウムイオンの置換率を50〜90ミリグラム当量/100gの範囲に調整する方法としては、交換性陽イオン量に、意図的に有機オニウム塩の添加量を調整することで、任意の置換率にする方法等が挙げられる。 As a method of adjusting the substitution rate of the organic onium ion to the exchangeable cation in the range of 50 to 90 milligram equivalent / 100 g, by adjusting the addition amount of the organic onium salt intentionally to the exchangeable cation amount, Examples of the method include an arbitrary substitution rate.
有機オニウム塩により層状珪酸塩の陽イオンを有機オニウムイオンに置換する処理としては、例えば、水中に分散した層状珪酸塩をイオン交換することにより行うことができる。 The treatment for replacing the cation of the layered silicate with the organic onium ion by the organic onium salt can be performed, for example, by ion exchange of the layered silicate dispersed in water.
本実施形態の有機化層状珪酸塩(B)は、シランカップリング剤で処理されていることが好ましい。有機化層状珪酸塩がシランカップリング剤で処理されている場合、有機化層状珪酸塩と樹脂との相溶性が向上し、樹脂中に有機化層状珪酸塩を多量に配合した場合でも層状珪酸塩同士の凝集を抑制することができる。その結果、得られるフィルムに、良好な透明性を維持した状態で、優れた寸法安定性を付与することが可能となる。 The organically modified layered silicate (B) of this embodiment is preferably treated with a silane coupling agent. When the organic layered silicate is treated with a silane coupling agent, the compatibility between the organic layered silicate and the resin is improved, and even when a large amount of the organic layered silicate is blended in the resin, the layered silicate Aggregation between each other can be suppressed. As a result, excellent dimensional stability can be imparted to the resulting film while maintaining good transparency.
シランカップリング剤としては、特に限定されないが、例えば、N−フェニル−3−アミノプロピルトリメトキシシラン、3−アミノプロピルトリメトキシシラン、3−アミノプロピルトリエトシシシラン、3−(2−アミノエチル)アミノプロピルトリメトキシシラン、3−(2−アミノエチル)アミノプロピルメチルジメトキシシラン、3−(2−アミノエチル)アミノプロピルトリエトキシシラン等のアミノシラン、ビニルトリメトキシシラン、ビニルトリエトキシシラン、ビニルトリアセトキシシラン等のビニルシラン、3−メタクリロキシプロピルトリメトキシシラン、3−メタクリロキシプロピルメチルジメトキシシラン等のメタクリルシラン、3−メルカプトプロピルトリメトキシシラン、3−メルカプトプロピルメチルジメトシシシラン、3−メルカプトプロピルエトキシシラン等のメルカプトシラン、3−グルシドキシプロピルトリメトキシシラン、3−グリシドキシプロピルメチルジメトキシシラン、3−グリシドキシプロピルトリエトキシシラン、3−グリシドキシプロピルメチルジエトキシシラン等のエポキシシラン、3−ウレイドプロピルトリエトキシシラン等のウレイドシラン、3−イソシアネートプロピルトリメトキシシラン、3−イソシアネートプロピルトリエトキシシラン等のイソシアネートシラン、メチルトリメトキシシラン、ジメチルジメトキシシラン、トリメチルメトキシシラン、エチルトリメトキシシラン、n−プロピルトリメトキシシラン、イソプロピルジメトキシシラン、イソブチルトリメトキシシラン、シクロヘキシルメチルジメトキシシラン、フェニルトリメトキシシラン等のアルキルシラン等が挙げられる。上記の中でも、ポリイミド樹脂との相溶性をより向上させる傾向にあるため、アミノシランが好ましい。 The silane coupling agent is not particularly limited. For example, N-phenyl-3-aminopropyltrimethoxysilane, 3-aminopropyltrimethoxysilane, 3-aminopropyltriethoxysilane, 3- (2-aminoethyl) Amino silane such as aminopropyltrimethoxysilane, 3- (2-aminoethyl) aminopropylmethyldimethoxysilane, 3- (2-aminoethyl) aminopropyltriethoxysilane, vinyltrimethoxysilane, vinyltriethoxysilane, vinyltriacetoxy Vinylsilanes such as silane, methacrylic silanes such as 3-methacryloxypropyltrimethoxysilane, 3-methacryloxypropylmethyldimethoxysilane, 3-mercaptopropyltrimethoxysilane, 3-mercaptopropylmethyldimethyl Mercaptosilane such as cissilane, 3-mercaptopropylethoxysilane, 3-glycidoxypropyltrimethoxysilane, 3-glycidoxypropylmethyldimethoxysilane, 3-glycidoxypropyltriethoxysilane, 3-glycidoxypropylmethyl Epoxy silane such as diethoxysilane, ureido silane such as 3-ureidopropyltriethoxysilane, isocyanate silane such as 3-isocyanatopropyltrimethoxysilane, 3-isocyanatopropyltriethoxysilane, methyltrimethoxysilane, dimethyldimethoxysilane, trimethyl Methoxysilane, ethyltrimethoxysilane, n-propyltrimethoxysilane, isopropyldimethoxysilane, isobutyltrimethoxysilane, cyclohexylmethyldi Tokishishiran, and the like alkyl silane and phenyl trimethoxy silane. Among these, aminosilane is preferred because it tends to improve compatibility with the polyimide resin.
有機化層状珪酸塩をシランカップリング剤で処理する方法としては、例えば、有機化層状珪酸塩が分散している溶液中で処理する湿式法、有機化層状珪酸塩を粉体のまま直接処理する乾式法、有機化層状珪酸塩が樹脂中に分散している樹脂組成物中で処理するインテグラルブレンド法が挙げられる。上記の中でも、シランカップリング剤による有機化層状珪酸塩の凝集を抑える観点から、有機化層状珪酸塩がよく分散している状態で処理できる湿式法、インテグラルブレンド法が好ましく、湿式法ではシランカップリング剤で処理後、有機化層状珪酸塩を溶液から単離することなく、溶液に分散したまま樹脂中に配合するのが好ましい。 Examples of the method for treating the organic layered silicate with a silane coupling agent include a wet method in which the organic layered silicate is treated in a solution in which the organic layered silicate is dispersed; Examples thereof include a dry method and an integral blend method in which a resin composition in which an organically modified layered silicate is dispersed in a resin. Among these, from the viewpoint of suppressing aggregation of the organic layered silicate by the silane coupling agent, the wet method and the integral blend method that can be processed in a state where the organic layered silicate is well dispersed are preferable. After the treatment with the coupling agent, the organically modified layered silicate is preferably blended in the resin while being dispersed in the solution without being isolated from the solution.
シランカップリング剤の添加量は、有機化層状珪酸塩に対して、好ましくは0.5〜10重量%であり、より好ましくは1〜5重量%である。シランカップリング剤の添加量が、0.5重量%以上であると、有機化層状珪酸塩と樹脂との相溶性が向上し、有機化層状珪酸塩同士の凝集が抑えられる傾向にあり、10重量%以下であると、シランカップリング剤による有機化層状珪酸塩同士の結合が起こり難くなる傾向にある。 The addition amount of the silane coupling agent is preferably 0.5 to 10% by weight, more preferably 1 to 5% by weight with respect to the organically modified layered silicate. When the addition amount of the silane coupling agent is 0.5% by weight or more, compatibility between the organically modified layered silicate and the resin is improved, and aggregation of the organically modified layered silicate tends to be suppressed. When the content is less than or equal to% by weight, bonding between the organically modified layered silicates by the silane coupling agent tends to be difficult to occur.
本実施形態のポリイミド樹脂組成物は、上記有機化層状珪酸塩(B)を溶媒に分散させた溶液と、上記ポリイミド(A)を含む溶液とを混合して、(B)成分を(A)成分中に分散させることにより得ることができる。ここで、有機化層状珪酸塩(B)はポリイミド(A)中に高度に分散していることが、寸法安定性及び水蒸気バリア性の観点から好ましい。ここで、「高度に」とは電子顕微鏡観察によりクレイの凝集がなく、デラミ及び分散が確認できる状態のことを言う。 In the polyimide resin composition of the present embodiment, a solution in which the organically modified layered silicate (B) is dispersed in a solvent and a solution containing the polyimide (A) are mixed, and the component (B) is added to the component (A). It can be obtained by dispersing in the component. Here, it is preferable from the viewpoint of dimensional stability and water vapor barrier properties that the organically modified layered silicate (B) is highly dispersed in the polyimide (A). Here, “highly” means a state in which delamination and dispersion can be confirmed without clay aggregation by observation with an electron microscope.
上記有機化層状珪酸塩(B)が分散した溶液、及びポリイミド(A)溶液に用いられる溶媒としては、例えば、N−N’−ジメチルホルムアミド、N−N’−ジメチルアセトアミド、N−メチル−2−ピロリドン等のアミド類;γ−ブチロラクトン、γ−バレロラクトン、δ−バレロラクトン等のラクトン類;エチレンカーボネート、プロピレンカーボネート等のカーボネート類;モノグライム、ジグライム、トリグライム、テトラグライム等のグライム類;及びジメチルスルホキシド等の非プロトン性極性溶媒類が挙げられる Examples of the solvent used in the solution in which the organic layered silicate (B) is dispersed and the polyimide (A) solution include NN′-dimethylformamide, NN′-dimethylacetamide, and N-methyl-2.

Preferably it is 40-100 weight part. When the blending amount of the component (B) is 20 parts by weight or less, the coefficient of thermal expansion tends to deteriorate or the water vapor transmission rate tends to decrease, and when it exceeds 250 parts by weight, the optical characteristics deteriorate or the film is formed. May become difficult and a film may not be obtained.
有機化層状珪酸塩(B)がシランカップリング処理されている場合、樹脂中に有機化層状珪酸塩を多量に配合した場合でも層状珪酸塩同士の凝集が起こり難くなるため、より多くの有機化層状珪酸塩を配合することが可能となる。この場合の、ポリイミド樹脂組成物中における有機化層状珪酸塩(B)の配合量は、ポリイミド(A)100重量部に対して、好ましくは100〜250重量部であり、より好ましくは130〜220重量部である。有機化層状珪酸塩(B)の配合量が上記範囲であると、良好な透明性を維持した状態で、寸法安定性をより一層向上させることができる。 When the organic layered silicate (B) is subjected to a silane coupling treatment, even when a large amount of the organic layered silicate is blended in the resin, it is difficult for the layered silicates to agglomerate. It becomes possible to mix | blend layered silicate. In this case, the amount of the organically modified layered silicate (B) in the polyimide resin composition is preferably 100 to 250 parts by weight, more preferably 130 to 220 parts per 100 parts by weight of the polyimide (A). Parts by weight. When the blending amount of the organically modified layered silicate (B) is within the above range, the dimensional stability can be further improved while maintaining good transparency.

Moreover, it can also be set as laminates, such as a flexible copper clad laminated board (CCL), as materials, such as a flexible printed circuit board.
また、上述のようにして得られたフィルムをさらに延伸することで、より熱膨張率が低く、透明性の高い複合フィルムを得ることができる。また、有機化層状珪酸塩(B)がフィルム面内方向に配向するため、より高度な水蒸気バリア性が得られる傾向にある。 Further, by further stretching the film obtained as described above, a composite film having a lower coefficient of thermal expansion and higher transparency can be obtained. Moreover, since the organically modified layered silicate (B) is oriented in the in-plane direction of the film, a higher water vapor barrier property tends to be obtained.
