本発明の導電性樹脂シートは、カーボンナノファイバーを含有する熱可塑性樹脂組成物によって形成したものである。この熱可塑性樹脂に配合するカーボンナノファイバーは、例えば、直径が数十ナノメータ以下、長さが数百ミクロンメータ以下であるナノサイズの極微細炭素繊維であり、内部が中空構造のカーボンナノチューブに限らず、内部が充填された構造のものを含み、炭素層が単層構造あるいは多層構造の何れの場合も含み、炭素層が螺旋構造に限らず、また炭素層が繊維の軸長方向に伸びた構造に限らず、炭素層が径方向に伸びた構造のものも含む。 The conductive resin sheet of the present invention is formed by a thermoplastic resin composition containing carbon nanofibers. Carbon nanofibers to be blended with this thermoplastic resin are, for example, nano-sized ultrafine carbon fibers having a diameter of several tens of nanometers or less and a length of several hundreds of micrometers or less, and are limited to carbon nanotubes having a hollow structure inside. In addition, including a structure filled inside, the carbon layer includes either a single layer structure or a multilayer structure, the carbon layer is not limited to a spiral structure, and the carbon layer extends in the axial direction of the fiber. Not only the structure but also a structure in which the carbon layer extends in the radial direction is included.

本発明の導電性樹脂シートにおいて、引張強度、および破断伸度は、引張試験機を用いて測定したものである。試験片の大きさは、シートを長さ１００ｍｍ、幅１０mmに切り取り測定した。引張強度は断面積あたりの強度に換算した値である。原熱可塑性樹脂に対する強度比とは、同一条件で作成したシートについて、カーボンナノファイバーを含有しない熱可塑性樹脂の引張強度ＰOに対して、同一の熱可塑性樹脂にカーボンナノファイバーを配合してなる熱可塑性樹脂組成物の引張強度ＰXの比（ＰX／ＰO）を％値で示したものである。破断伸度は、試験前の長さＬ0に対して、破断時の長さＬXの比（ＬX／ＬO）を％値で示したものである。 In the conductive resin sheet of the present invention, the tensile strength and elongation at break are measured using a tensile tester. The size of the test piece was measured by cutting a sheet into a length of 100 mm and a width of 10 mm. The tensile strength is a value converted into strength per cross-sectional area. The intensity ratio Haranetsu thermoplastic resin, the sheet prepared under the same conditions, with respect to tensile strength P O of the thermoplastic resin containing no carbon nanofiber, by blending the carbon nanofibers in the same thermoplastic resin The ratio (P X / P O ) of the tensile strength P X of the thermoplastic resin composition is shown as a% value. The elongation at break is the ratio (L X / L O ) of the length L X at break to the length L 0 before the test, expressed as a% value.
本発明の導電性樹脂シートは、上記破断伸度が３０％以上であって上記強度比１００％以上である。好ましくは、体積抵抗値が１０9Ωcm以下、および上記破断伸度５０％以上であって上記強度比１００％以上である。一方、熱可塑性樹脂にカーボンブラック等を配合してなる従来の導電性樹脂シートにおいて、実用に適う程度の導電性を有するものの破断伸度は１０％以下であり、また原熱可塑性樹脂に対する強度比は概ね８０％以下である。従って、本発明の導電性樹脂シートは、従来の導電性樹脂シートよりも強度および加工性が格段に優れている。 The conductive resin sheet of the present invention has a breaking elongation of 30% or more and a strength ratio of 100% or more. Preferably, the volume resistance value is 10 9 Ωcm or less, the breaking elongation is 50% or more, and the strength ratio is 100% or more. On the other hand, in a conventional conductive resin sheet formed by blending carbon black or the like with a thermoplastic resin, the elongation at break is 10% or less, although it has a conductivity suitable for practical use, and the strength ratio with respect to the raw thermoplastic resin Is approximately 80% or less. Therefore, the conductive resin sheet of the present invention is remarkably superior in strength and workability than the conventional conductive resin sheet.
本発明の導電性樹脂シートは、体積抵抗値１.０Ωcm以下およびＤＢＰ吸油量１５０ml/100g以上のカーボンナノファイバーを含有する熱可塑性樹脂組成物によって形成することができる。ＤＢＰ吸油量が１５０ml/100gよりも少ないカーボンナノファイバーは樹脂中の分散性が劣り、凝集しやすいので樹脂組成物の導電性が不均一になり、さらに樹脂組成物の加工性が低下するので好ましくない。また、体積抵抗値が１.０Ωcmより大きいカーボンナノファイバーは導電性が不十分である。 The conductive resin sheet of the present invention can be formed of a thermoplastic resin composition containing carbon nanofibers having a volume resistance of 1.0 Ωcm or less and a DBP oil absorption of 150 ml / 100 g or more. Carbon nanofibers with a DBP oil absorption of less than 150 ml / 100 g are preferred because they have poor dispersibility in the resin and tend to aggregate, making the resin composition non-uniform in conductivity and further reducing the processability of the resin composition. Absent. Carbon nanofibers having a volume resistance value greater than 1.0 Ωcm have insufficient conductivity.
体積抵抗値１.０Ωcm以下およびＤＢＰ吸油量が１５０ml/100ｇ以上のカーボンナノファイバーは、触媒を用いた気相成長法において、触媒および原料の混合ガス組成を調整することによって製造することができる。具体的には、例えば、触媒粒子としてＦｅ、Ｎｉ、Ｃｏ、Ｍｎ、Ｃｕの酸化物から選ばれた１種または２種以上と、Ｍｇ、Ｃa、Ａｌ、Ｓｉの酸化物から選ばれた１種または２種以上の混合酸化物粉末を用い、４００℃〜８００℃の温度で、一酸化炭素または二酸化炭素と水素の混合ガスを上記触媒粒子に接触させて、カーボンナノファイバーを製造する気相成長法において、触媒としてＣｏ酸化物とＭｇ酸化物の混合酸化物あるいは、Ｍｇ酸化物にＣｏ酸化物が被覆された複合酸化物を用い、原料混合ガスを一酸化炭素および/または二酸化炭素と水素とし、その混合比をＣＯ/Ｈ2＝５０／５０〜９９／１に調整し、好ましくは、さらに反応後に連続して反応温度と同一温度下で水素ガスで１０分間以上処理することによって、体積抵抗値が低くＤＢＰ吸油量が高いカーボンナノファイバーを製造することができる。 Carbon nanofibers having a volume resistance of 1.0 Ωcm or less and a DBP oil absorption of 150 ml / 100 g or more can be produced by adjusting the mixed gas composition of the catalyst and the raw material in the vapor phase growth method using the catalyst. Specifically, for example, the catalyst particles are one or more selected from oxides of Fe, Ni, Co, Mn, and Cu and one selected from oxides of Mg, Ca, Al, and Si. Alternatively, vapor phase growth in which carbon nanofibers are produced by using two or more mixed oxide powders and contacting carbon monoxide or a mixed gas of carbon dioxide and hydrogen with the catalyst particles at a temperature of 400 ° C. to 800 ° C. In this method, a mixed oxide of Co oxide and Mg oxide or a composite oxide in which a Mg oxide is coated with a Co oxide is used as a catalyst, and the raw material mixed gas is carbon monoxide and / or carbon dioxide and hydrogen. The volume ratio is adjusted by adjusting the mixing ratio to CO / H 2 = 50/50 to 99/1, preferably by further treating with hydrogen gas for 10 minutes or more continuously at the same temperature as the reaction temperature after the reaction. value Can ku DBP oil absorption of producing high carbon nanofiber.
本発明において用いるカーボンナノファイバーは、直径５〜１００nmおよびアスペクト比１０以上であるものが好ましい。このサイズのものは極微細な繊維であるので樹脂中に均一に分散しやすく、かつ互いに接触しやすいので、均一な導電性を得るのに都合が良い。 The carbon nanofibers used in the present invention preferably have a diameter of 5 to 100 nm and an aspect ratio of 10 or more. Since this size is an extremely fine fiber, it is easy to uniformly disperse in the resin and easily come into contact with each other, which is convenient for obtaining uniform conductivity.
また、上記カーボンナノファイバーはＢＥＴ比表面積４００m2/g以下、好ましくは３００m2/g以下であるものが良い。ＢＥＴ比表面積がこれより大きいと樹脂との接触面積が過大になり、樹脂の物性が損なわれ、樹脂自体が本来有する強度や混練時ないし成形時の粘度が高くなり、流動性が失われるので好ましくない。 The carbon nanofibers should have a BET specific surface area of 400 m 2 / g or less, preferably 300 m 2 / g or less. If the BET specific surface area is larger than this, the contact area with the resin becomes excessive, the physical properties of the resin are impaired, the inherent strength of the resin itself and the viscosity at the time of kneading or molding are increased, and fluidity is lost. Absent.
本発明の導電性樹脂シートを形成する樹脂組成物のカーボンナノファイバーの含有量は、熱可塑性樹脂１００重量部に対する該カーボンナノファイバーの表面積換算値（カーボン含有量×比表面積の値）で２０００ｍ2以下が好ましい。実施例１〜５では比表面積２５０〜２８０ｍ 2 /ｇのカーボンナノファイバーを３〜７wt％含有している。カーボンナノファイバーの含有量がこれより多いと引張強度や伸度などの樹脂物性が大きく低下するので好ましくない。
The content of the carbon nanofibers in the resin composition forming the conductive resin sheet of the present invention is 2000 m 2 in terms of the surface area of the carbon nanofibers (carbon content × specific surface area) relative to 100 parts by weight of the thermoplastic resin. The following is preferred. Examples 1 to 5 contain 3 to 7 wt% of carbon nanofibers having a specific surface area of 250 to 280 m 2 / g. If the carbon nanofiber content is higher than this, the resin physical properties such as tensile strength and elongation are greatly lowered, which is not preferable.
上記樹脂組成物は、カーボンナノファイバーと共に、機械的強度等を大きく損なわない範囲内で、カーボンブラックなどの導電性微粒子や難燃剤、分散安定剤などを含有してもよい。 The resin composition may contain conductive fine particles such as carbon black, a flame retardant, a dispersion stabilizer, and the like within a range that does not significantly impair mechanical strength and the like together with the carbon nanofibers.
以下に本発明の実施例を比較例と共に示す。なお、ＰＣシートの作成方法および評価方法は下記のとおりである。また、本発明の導電性樹脂シートにおいて、引張強度および破断伸度は引張試験機を用いて測定した。試験片の大きさは、シートを長さ１００mm、幅１０mmに切り取り測定した。引張強度は、断面積あたりの強度に換算して計算した。
〔ＰＣシートの作成方法〕：予め所定量のカーボンナノファイバーを含有したＰＣ樹脂コンパウンドを作成し、それを射出押し出しフィルム成形加工で所定の厚みに成形することにより導電性シートを得た。
〔体積抵抗値〕：市販の測定装置（油化電子社製：ロレスタ−ＡＰ）を用い、４端子法により体積抵抗を求めた。
Examples of the present invention are shown below together with comparative examples. In addition, the preparation method and evaluation method of a PC sheet are as follows. In the conductive resin sheet of the present invention, the tensile strength and the breaking elongation were measured using a tensile tester. The size of the test piece was measured by cutting a sheet into a length of 100 mm and a width of 10 mm. The tensile strength was calculated in terms of strength per cross-sectional area.
[Preparation Method of PC Sheet]: A PC resin compound containing a predetermined amount of carbon nanofibers was prepared in advance, and formed into a predetermined thickness by injection extrusion film forming process to obtain a conductive sheet.
[Volume resistance value]: Volume resistance was determined by a four-terminal method using a commercially available measuring device (Yureka Electronics Co., Ltd .: Loresta-AP).
本発明の導電性樹脂シートはカーボンナノファイバーの配合量が３〜７重量％であるものは、カーボンブラックを１５重量％配合した比較例１よりも体積抵抗値が小さく、導電性に優れている。また、比較例１の破断伸度は５％、引張強度４５％であるのに対して、本発明の導電性樹脂シートは破断伸度９０〜１３０、引張強度５７〜６３であり、伸長性が格段に優れており、引張強度も大きい。さらに、ＤＢＰ吸油量が少ない従来のカーボンナノフィバーを用いた比較例２はカーボンナノファイバーの配合量が３重量％でシート状に成形することができず、格段に加工性が劣る。 In the conductive resin sheet of the present invention, the carbon nanofiber blending amount of 3 to 7% by weight has a smaller volume resistance than Comparative Example 1 in which carbon black is blended by 15% by weight and is excellent in conductivity. . Further, the breaking elongation of Comparative Example 1 is 5% and the tensile strength is 45%, whereas the conductive resin sheet of the present invention has a breaking elongation of 90 to 130 and a tensile strength of 57 to 63, and has an extensibility. It is remarkably superior and has high tensile strength. Further, Comparative Example 2 using the conventional carbon nanofibre with a small DBP oil absorption amount cannot be formed into a sheet shape with a blending amount of carbon nanofibers of 3% by weight, and the processability is remarkably inferior.
