Description
本発明は、炭素繊維の表面処理技術に係り、炭素繊維の表面の油剤を効果的に交換できる、炭素繊維の表面の油剤の交換方法を提供することを旨とする。 The present invention relates to a carbon fiber surface treatment technique, and an object thereof is to provide a method for replacing an oil agent on the surface of a carbon fiber, which can effectively replace the oil agent on the surface of the carbon fiber.
炭素繊維は、炭化繊維とも称し、それは優れた力学特性及び電気特性を有するため、各種の用途に広汎に応用することができる。現在、坊間によく見られる炭素繊維の多くはポリアクリロニトリル系繊維などの炭素繊維の前駆体繊維（ｐｒｅｃｕｒｓｏｒ ｆｉｂｅｒ）を束にしてなる炭素繊維前駆体繊維束にか焼を行って得られたものである。 Carbon fiber is also referred to as carbonized fiber, which has excellent mechanical and electrical properties and can be widely applied to various applications. At present, most of the carbon fibers that are often found in Bobo are obtained by calcining carbon fiber precursor fiber bundles made of bundles of carbon fiber precursor fibers such as polyacrylonitrile fibers. is there.
処理を経ていない炭素繊維の表面は、粘着性が不足し、しかもそれは不良な横方向性質を有し、例えば、分離強度及び剪断強度などを有するため、直接に利用するものは比較的に少ないことが分かり、通常、用途に従って基質樹脂と組み合わせる炭素繊維複合材料を成形する一方、炭素繊維及び石墨繊維が特別に硬くて脆いので、接着可能性、曲げ力や耐摩耗性を欠き、それが工場から出庫する前に大抵表面に１層の油剤（糊付け剤）を塗布しておくことで、繊維が摩擦による断裂してしまうことがないように保護できるようになっている。 The surface of the carbon fiber that has not been treated is not sticky enough, and it has poor lateral properties, such as separation strength and shear strength, so that there are relatively few to use directly. While usually forming carbon fiber composites to be combined with substrate resin according to the application, carbon fiber and graphite fiber are specially hard and brittle, so they lack adhesion, bending force and wear resistance from the factory By applying a single layer of oil (glue agent) to the surface before leaving, it is possible to protect the fibers from tearing due to friction.
従来、炭素繊維複合材料では、炭素繊維の優れた機械特性を完全に利用して、その基質樹脂として熱硬化型樹脂材料を採用することが多く、いわゆる熱硬化型炭素繊維複合材料になり、熱可塑型炭素繊維複合材料との最大の差異性は、伝統的な熱硬化型炭素繊維複合材料の成形時間が長いので、金型の使用率が比較的に低くなり、生産能力も相対的に比較的に低くなることである。 Conventionally, in carbon fiber composite materials, the excellent mechanical properties of carbon fibers are fully utilized, and thermosetting resin materials are often used as the substrate resin, resulting in so-called thermosetting carbon fiber composite materials. The biggest difference from plastic type carbon fiber composite material is that the molding time of traditional thermosetting carbon fiber composite material is long, so the usage rate of mold is relatively low, and the production capacity is also comparatively compared Is to lower.
しかしながら、現在、市販の炭素繊維原料の表面の油剤は、依然として大多数が熱硬化型樹脂の湿潤性に基づいて設計した熱硬化型樹脂油剤であり、もしさらにこの類の炭素繊維原料を熱可塑型炭素繊維複合材料になるように作製するには、その炭素繊維原料と樹脂との間では界面が不整合になるため、健全な接合界面を形成できないことが、射出成形を主要な加工手段とする各種の電気、電子部品、機械部品や自動車部品などの製品に応用することができない主因となっていた。 However, at present, the majority of commercially available carbon fiber raw materials are still thermosetting resin oils designed on the basis of the wettability of thermosetting resins. In order to produce a carbon fiber composite material, the interface between the carbon fiber raw material and the resin becomes inconsistent, so that a sound joint interface cannot be formed. It was the main reason why it could not be applied to products such as various electrical, electronic parts, mechanical parts and automobile parts.
これに鑑みて、本発明は、つまり炭素繊維の表面の油剤を効果的に交換できる、炭素繊維の表面の油剤の交換方法を提供することを主要な目的とするものである。 In view of this, the main object of the present invention is to provide a method for replacing the oil agent on the surface of the carbon fiber, which can effectively replace the oil agent on the surface of the carbon fiber.

本発明は、主に炭素繊維の表面の油剤を効果的に交換できる、炭素繊維の表面の油剤の交換方法を提供し、図１に示すように、本発明の炭素繊維の表面の油剤の交換方法は、基本的に順次に下記の工程を含み、すなわち原料供給工程、糊抜き工程、プラズマ表面処理工程及び糊付け工程などの工程を含む。なお、図２〜図５を参照しながら、さらに各工程の実施可能な形態について以下のように説明する。 The present invention provides a method for exchanging an oil agent on the surface of carbon fiber, which can effectively exchange the oil agent on the surface of the carbon fiber, and as shown in FIG. The method basically includes the following steps in sequence: a raw material supply step, a desizing step, a plasma surface treatment step, and a gluing step. In addition, referring to FIG. 2 to FIG. 5, embodiments in which each process can be performed will be described as follows.
前記原料供給工程において、主に炭素繊維１１の表面に第１種の油剤１２が被覆される炭素繊維原料１０を提供する。かかる前記炭素繊維１１は、レーヨン、ポリビニルアルコール、ポリ塩化ビニリデン、ポリアクリロニトリル（ｐｏｌｙａｃｒｙｌｏｎｉｔｒｉｌｅ，ＰＡＮ）、ピッチ（ｐｉｔｃｈ）などの前駆体繊維を束にしてなる炭素繊維前駆体繊維束にか焼を行って得られたものである。実施時、かかる前記第１種の油剤１２が、熱硬化型樹脂油剤であってもよい。 In the raw material supplying step, a carbon fiber raw material 10 is provided in which the surface of the carbon fiber 11 is mainly coated with the first type oil agent 12. The carbon fiber 11 is calcined into a carbon fiber precursor fiber bundle in which precursor fibers such as rayon, polyvinyl alcohol, polyvinylidene chloride, polyacrylonitrile (PAN), and pitch are bundled. It is obtained. At the time of implementation, the first-type oil agent 12 may be a thermosetting resin oil agent.

At the time of implementation, desizing can be performed under conditions of high temperature of 250 to 650 ° C. and time of 1 to 60 seconds (sec), or desizing using a method of cleaning the surface of the carbon fiber raw material 10 with an organic solvent. It can be performed. In an embodiment in which desizing is performed using a method of cleaning the surface of the carbon fiber raw material 10 with the organic solvent, the organic solvent may be acetone or chloroform.
前記プラズマ表面処理工程において、予め設定されたパワーのプラズマガス流を前記第１種の油剤１２を除去した炭素繊維１１に予め設定された時間作用させることにより、前記炭素繊維１１の表面に相対的に粗面化したプラズマ改質構造１１１を形成する（図４参照）。 In the plasma surface treatment step, a plasma gas flow having a preset power is allowed to act on the carbon fiber 11 from which the first type of oil agent 12 has been removed for a preset time, thereby making the plasma gas flow relatively to the surface of the carbon fiber 11. A plasma-modified structure 111 having a rough surface is formed (see FIG. 4).
前記糊付け工程において、前記表面に形成された前記プラズマ改質構造１１１の炭素繊維１１の表面に第２種の油剤１３を被覆することによって、表面に前記第２種の油剤１３を有する炭素繊維原料１０が得られる（図５参照）。実施時、浸漬やパディングなどの方式を採用して前記第２種の油剤１３を前記炭素繊維１１の表面に被覆することができる。かかる前記第２種の油剤１３に至っては熱硬化型樹脂油剤、又は熱可塑型樹脂油剤であってもよい。かかる前記第２種の油剤１３が熱可塑型樹脂油剤である実施形態において、かかる前記第２種の油剤１３が、ポリウレタン（ＰＵ）、ポリエチレン（ＰＥ）、ポリプロピレン（ＰＰ）又はアクリル（Ａｃｒｙｌｉｃ）系のいずれか１つであってもよい。 In the gluing step, the carbon fiber raw material having the second type oil agent 13 on the surface by coating the surface of the carbon fiber 11 of the plasma modified structure 111 formed on the surface with the second type oil agent 13. 10 is obtained (see FIG. 5). At the time of implementation, the surface of the carbon fiber 11 can be coated with the second type oil agent 13 by employing a method such as dipping or padding. The second type of oil 13 may be a thermosetting resin oil or a thermoplastic resin oil. In the embodiment in which the second type of oil 13 is a thermoplastic resin oil, the second type of oil 13 is polyurethane (PU), polyethylene (PE), polypropylene (PP), or acrylic. Any one of these may be sufficient.
これによれば、本発明の炭素繊維の表面の油剤の交換方法は、相対的により積極的で信頼性のある手段で、炭素繊維の表面の油剤を所期の油剤に置き換えることができる。とりわけ、市販の炭素繊維原料１０の表面に既に有する熱硬化型樹脂油剤から熱可塑型樹脂油剤への置き換えに適していることにより、射出成形を主要な加工手段とする各種の電気、電子部品、機械部品や自動車部品などの製品に応用することができる。 According to this, the method for replacing the oil agent on the surface of the carbon fiber of the present invention can replace the oil agent on the surface of the carbon fiber with the intended oil agent by a relatively more aggressive and reliable means. In particular, various electrical and electronic components that use injection molding as the main processing means by being suitable for replacement of thermosetting resin oils already on the surface of commercially available carbon fiber raw material 10 with thermoplastic resin oils, It can be applied to products such as machine parts and automobile parts.
プラズマ表面処理過程において、パワーが１００〜１００００ワット（Ｗ）である大気プラズマガス流、低圧プラズマガス流、マイクロ波プラズマガス流やグロ−プラズマガス流などを使用して、前記炭素繊維に１０〜１０００ミリ秒（ｍｓｅｃ）作用させることができる。プラズマガス流にエネルギーを有する粒子を含むので、プラズマガス流の物理反応（衝撃）及び化学反応作用を介して本来炭素繊維１１の表面に付着した不純物が分子化され、ひいては吹き飛ばされることにより、炭素繊維１１の表面を粗面化すると同時に、炭素繊維１１の表面の官能基を増加させ、炭素繊維１１の後続の糊付け過程において、炭素繊維１１と熱可塑型樹脂油剤との良好な界面接合を図ることに寄与することから、後続の工芸で形成した炭素繊維複合材料の特性表現を向上させることができる。 In the plasma surface treatment process, an atmospheric plasma gas flow, a low-pressure plasma gas flow, a microwave plasma gas flow, a glow plasma gas flow, or the like having a power of 100 to 10000 watts (W) is used for the carbon fiber. It can be applied for 1000 milliseconds (msec). Since the plasma gas flow contains energetic particles, the impurities originally attached to the surface of the carbon fiber 11 through the physical reaction (impact) and chemical reaction of the plasma gas flow are molecularized and then blown away, thereby At the same time that the surface of the fiber 11 is roughened, the functional groups on the surface of the carbon fiber 11 are increased, and in the subsequent gluing process of the carbon fiber 11, good interfacial bonding between the carbon fiber 11 and the thermoplastic resin oil is achieved. Therefore, it is possible to improve the characteristic expression of the carbon fiber composite material formed by the subsequent craft.
さらに、本発明におけるプラズマ表面処理は、乾式に属する表面処理技術であるため、炭素繊維１１に付加的な不純物や沈澱物を生成するのを回避できるのみならず、相対的に炭化繊維１１のプラズマ表面処理工程を完了した後の乾燥工数、作業手順を低減することもできる。勿論、本発明の炭素繊維の表面の油剤の交換方法も、図６に示すように、前記糊付け工程の後、前記第２種の油剤１３を有する炭素繊維原料１０に対して少なくとも１つの乾燥工程を施し、例えば、焼成や風乾などの方式を介して前記第２種の油剤１３を前記炭素繊維１１の表面に強固に付着させることができる。 Furthermore, since the plasma surface treatment in the present invention is a dry surface treatment technique, it is possible not only to avoid the generation of additional impurities and precipitates on the carbon fiber 11 but also to relatively plasma the carbonized fiber 11. It is also possible to reduce the number of drying steps and work procedures after completing the surface treatment process. Of course, in the method of replacing the oil agent on the surface of the carbon fiber of the present invention, as shown in FIG. 6, after the gluing step, at least one drying step is performed on the carbon fiber raw material 10 having the second type oil agent 13. For example, the second type oil agent 13 can be firmly attached to the surface of the carbon fiber 11 through a method such as firing or air drying.
具体的に言えば、本発明で開示した炭素繊維の表面の油剤の交換方法は、とりわけ市販の炭素繊維原料の表面に既に有する熱硬化型樹脂油剤から熱可塑型樹脂油剤への置き換えに適していることにより、射出成形を主要な加工手段とする各種の電気、電子部品、機械部品や自動車部品などの製品に応用することができる。特に、プラズマ表面処理を介して炭素繊維の表面を粗面化すると同時に、炭素繊維の表面の官能基を増加させることができ、炭素繊維の後続の糊付け過程において、炭素繊維と熱可塑型樹脂油剤との良好な界面接合を図ることに寄与することから、後続の工芸で形成した炭素繊維複合材料の特性表現を向上させることができる。 Specifically, the method for exchanging the oil on the surface of the carbon fiber disclosed in the present invention is particularly suitable for replacing the thermosetting resin oil already on the surface of the commercially available carbon fiber raw material with the thermoplastic resin oil. Therefore, it can be applied to various electric, electronic parts, mechanical parts, automobile parts and other products having injection molding as a main processing means. In particular, it is possible to roughen the surface of the carbon fiber through plasma surface treatment and at the same time increase the functional group on the surface of the carbon fiber, and in the subsequent gluing process of the carbon fiber, the carbon fiber and the thermoplastic resin oil agent Therefore, it is possible to improve the characteristic expression of the carbon fiber composite material formed by the subsequent craft.
