Description
本発明は、導電性エポキシ樹脂塗床組成物に関する。 The present invention relates to a conductive epoxy resin coating composition.
従来、エポキシ樹脂は耐久性、耐薬品性もあり、常温での硬化が可能なため、塗り床に使用されている。一方、静電気により、樹脂フィルム包装などの帯電し易い工程を行う場所では引火による火災や、半導体や精密電子部品を扱う工場ではデバイスの破壊などの事故の可能性があり、これを防止するために塗り床材に帯電防止性能が求められ、エポキシ樹脂に導電性材料を配合した床材が用いられている。 Conventionally, epoxy resins have durability and chemical resistance, and can be cured at room temperature. On the other hand, due to static electricity, there is a possibility of an accident such as a fire due to ignition in a place where a process such as resin film packaging is easy to be charged, or destruction of a device in a factory handling semiconductors or precision electronic parts. Antistatic performance is required for the coating floor material, and a flooring material in which a conductive material is blended with an epoxy resin is used.
この導電性床材には、薄付けエポキシ樹脂塗床と厚付けエポキシ樹脂塗床があり、前者はエポキシ樹脂を溶剤で希釈したもので、塗布厚０．０５〜０．２ｍｍで、工期は短いものの、耐久性に劣るものであり、後者は無溶剤でまたは希釈溶剤は殆ど使用せず、塗布厚０．５〜１ｍｍであり、耐久性はあるものの、導電性と外観、耐久性をすべて満たすことは難しい状況であった。 This conductive floor material includes a thin epoxy resin coating layer and a thick epoxy resin coating layer. The former is a solution obtained by diluting an epoxy resin with a solvent, and has a coating thickness of 0.05 to 0.2 mm and a short construction period. However, it is inferior in durability.

特許文献１の炭素繊維は等方性ピッチ系で短繊維であり、分散が十分にできず、炭素繊維の有効分散性が低く外観が瑕疵ができ易く、黒色炭素繊維が目立つものとなっていた。 The carbon fiber of Patent Document 1 is an isotropic pitch-based short fiber, cannot be sufficiently dispersed, the carbon fiber has low effective dispersibility, and the appearance is easily wrinkled, and the black carbon fiber is conspicuous. .

本発明の導電性エポキシ樹脂塗床組成物は塗付作業性が良く、外観瑕疵が少ない特徴がある。 The conductive epoxy resin coating floor composition of the present invention is characterized by good coating workability and less appearance wrinkles.
本発明は炭素繊維と導電性酸化亜鉛を導電材料として使用し、耐久性のある厚付け導電塗床が得られる。厚付け塗床に導電性を付与する場合、導電性材料が、エポキシ樹脂の硬化の過程で、沈降が起き、導電性の悪化を引き起こす、炭素繊維等の繊維を配合してこれを防ぐこともされているが、炭素繊維の分散が十分にできず、外観異常や、結束繊維が見え、淡色で、違和感が生じる等の問題を有していた。本発明は長繊維炭素繊維にエポキシ樹脂がサイズされ、裁断されたチョップドファイバーを予め液状エポキシ樹脂組成物に分散し、これに導電性酸化亜鉛粉末を配合することで、これらの問題を解消した。 The present invention uses carbon fiber and conductive zinc oxide as a conductive material to obtain a durable thick conductive coating floor. When imparting conductivity to thick coating floors, the conductive material may prevent this by compounding fibers such as carbon fibers that cause sedimentation during the curing of the epoxy resin and cause deterioration of conductivity. However, the carbon fibers could not be sufficiently dispersed, and there were problems such as abnormal appearance, bundling fibers, light colors, and uncomfortable feeling. The present invention has solved these problems by dispersing the chopped fiber in which the epoxy resin is sized and cut into the long-fiber carbon fiber in advance in the liquid epoxy resin composition, and adding conductive zinc oxide powder thereto.
本発明に用いる炭素繊維は長繊維のもので、エポキシ樹脂でサイズされたものを用い、３〜６ｍｍ長に裁断されたチョップドカーボンファイバーを用いる。短繊維のものは直線性が劣り、開繊が不十分となり、仕上がり面で欠点が生じ易く、炭素繊維の導電性を有効に導くことができない。長繊維であれば、連続処理で、均一で、少量のサイズ加工ができ、エポキシ樹脂塗床組成物へ炭素繊維分散が容易であり、組成物硬化への影響もない。炭素繊維の重量に対して１〜３重量％が好ましい。長繊維の炭素繊維としてはＰＡＮ系や異方ピッチ系があり、繊維径７μｍ及び同等の効果を有する範囲が好ましい。サイズ剤として、エポキシ樹脂のうち、ビスフェノール型エポキシ樹脂が好ましい。 The carbon fiber used in the present invention is a long fiber, which is sized with an epoxy resin, and a chopped carbon fiber cut to a length of 3 to 6 mm is used. Short fibers are inferior in linearity, have insufficient fiber opening, tend to have defects in finish, and cannot effectively lead to the conductivity of carbon fibers. If it is a long fiber, it can be processed in a uniform and small amount by continuous treatment, and the carbon fiber can be easily dispersed in the epoxy resin coating composition, and there is no influence on the curing of the composition. It is preferably 1 to 3% by weight based on the weight of the carbon fiber. As long carbon fibers, there are PAN type and anisotropic pitch type, and a fiber diameter of 7 μm and a range having an equivalent effect are preferable. Of the epoxy resins, a bisphenol type epoxy resin is preferable as the sizing agent.
導電性酸化亜鉛は酸化亜鉛に異種元素をド−プしたもので、アルミニウムをドープしたものがある。粒径は体積平均径(DV)４〜７μｍ或いは同等の効果を有する範囲で、粒径が小さいと組成物の塗膜導電性が得られず、粘度が上昇して作業性が得られない。粒径が大きすぎると粘度が低く組成物の保存安定性が得られない。 Conductive zinc oxide is a zinc oxide doped with a different element, and is doped with aluminum. The particle diameter is in the range of volume average diameter (DV) of 4 to 7 μm or an equivalent effect. If the particle diameter is small, the coating film conductivity of the composition cannot be obtained, and the viscosity is increased and workability cannot be obtained. If the particle size is too large, the viscosity is low and the storage stability of the composition cannot be obtained.
本発明の炭素繊維を液状エポキシ樹脂組成物へ分散させる方法は剪断がかかる方法であれば、良く、ロール間圧力を利用した圧縮作用と、周速度が異なるロール間でのせん断作用により分散を行うものでロールミルが好ましく。３本ロールミルが好ましい。 The method of dispersing the carbon fiber of the present invention in the liquid epoxy resin composition is good as long as it is a shearing method, and the dispersion is performed by the compression action utilizing the pressure between the rolls and the shearing action between the rolls having different peripheral speeds. A roll mill is preferable. A three roll mill is preferred.
予め炭素繊維を分散する液状エポキシ樹脂組成物はロールミルの特性や導電性エポキシ樹脂塗床組成物に適う範囲で、発生する熱、或いは冷却等により適宜選択する。例えばビスフェノールＡ型液状樹脂に反応性希釈剤等を配合した液状エポキシ樹脂組成物とする。 The liquid epoxy resin composition in which the carbon fibers are dispersed in advance is appropriately selected depending on the heat generated, cooling, or the like within a range suitable for the properties of the roll mill and the conductive epoxy resin coating composition. For example, it is set as the liquid epoxy resin composition which mix | blended the reactive diluent etc. with the bisphenol A liquid resin.
本発明に用いるエポキシ樹脂は硬化剤と組み合わせて硬化条件に合わせて選択する。ビスフェノールＡ型エポキシ樹脂、ビスフェノールＦ型エポキシ樹脂、反応性希釈剤などエポキシ基を有するもので、反応性、硬度、接着力等で適宜単独或いは複数種類を配合できる。 The epoxy resin used in the present invention is selected according to curing conditions in combination with a curing agent. It has an epoxy group such as a bisphenol A type epoxy resin, a bisphenol F type epoxy resin, a reactive diluent, etc., and can be used alone or in a plurality of types depending on reactivity, hardness, adhesive force and the like.
本発明のエポキシ樹脂硬化剤はアミノ基、メルカプト基を有する硬化剤等を組み合わせることができ、本発明で最も適する塗り床の使途で、導電性をより発現させ易くするため、脂肪族ポリアミン、変性脂肪族ポリアミン、ポリアミドアミン、ポリアミド、脂環式ポリアミン、変性脂環式ポリアミン、変性芳香族ポリアミン、３級アミン等のアミン化合物が挙げられ、例えば、ポリエチレンテトラミン、テトラエチレンペンタミン、ジエチルアミノプロピルアミン、N-アミノエチルピペラジン、イソホロンジアミン、２，４，６−トリスジメチルアミノメチルフェノール、メタキシレンジアミン等が挙げることができる。好ましくは変性脂肪族ポリアミン系の硬化剤である。 The epoxy resin curing agent of the present invention can be combined with a curing agent having an amino group, a mercapto group, etc., and in order to make the conductivity more easily expressed by using the most suitable coating floor in the present invention, aliphatic polyamine, modified Examples include aliphatic polyamines, polyamidoamines, polyamides, alicyclic polyamines, modified alicyclic polyamines, modified aromatic polyamines, tertiary amines, and other amine compounds, such as polyethylenetetramine, tetraethylenepentamine, diethylaminopropylamine, N-aminoethylpiperazine, isophoronediamine, 2,4,6-trisdimethylaminomethylphenol, metaxylenediamine and the like can be mentioned. A modified aliphatic polyamine-based curing agent is preferred.
本発明の導電性エポキシ樹脂塗床組成物は塗布作業と硬化性を作業環境に応じて適宜選択する。塗布作業が良好な粘度を選択し、可使時間即ち硬化性を低くすると導電性材料、主に導電性酸化亜鉛が沈降し、導電性が低下する。また、色合いも沈降の影響を受ける。仕上がりに影響を大きく与える炭素繊維は導電性エポキシ樹脂塗床組成物の０．２５重量％以下が好ましく、導電性酸化亜鉛は、３４重量％以下が好ましく、塗布作業性から、３２重量％以下がさらに好ましい。両者の下限は必要とされる導電性により適宜選択されるが、塗布量１ｋｇ／ｍ２でも１０５を導電性を有することとすると炭素繊維は０．１５重量％以上、導電性酸化亜鉛が２５重量％以上或いは同等の効果が得られる下限以上が好ましい。同等の効果が得られる下限とは例えば、実施例では配合容易性を考慮した配合としいるが、必須効果として、導電性、隠蔽性、塗布作業性とした場合、実施例と同等の効果が得られる下限を言う。 In the conductive epoxy resin coating composition of the present invention, the application work and curability are appropriately selected according to the work environment. When a viscosity with a good coating operation is selected and the pot life, that is, the curability is lowered, the conductive material, mainly the conductive zinc oxide, precipitates and the conductivity is lowered. The hue is also affected by sedimentation. The carbon fiber that greatly affects the finish is preferably 0.25% by weight or less of the conductive epoxy resin coating composition, and the conductive zinc oxide is preferably 34% by weight or less. Further preferred. Is appropriately selected according to the conductivity limit of both are required, it that the carbon fiber is 0.15% by weight or more having conductivity 10 5 even coating weight 1 kg / m 2, conductive zinc oxide 25 It is preferably at least% by weight or more than the lower limit at which an equivalent effect is obtained. The lower limit at which the same effect can be obtained is, for example, a formulation that takes into account the ease of blending in the examples. However, if the essential effects are conductivity, concealment, and coating workability, the same effects as in the examples are obtained. Say the lower bound.
