Abstract
Description
本発明は、軽量で、機械的強度の高い成形体が得られるプロピレン系樹脂組成物とそれから得られる成形体に関する。 The present invention relates to a propylene-based resin composition capable of obtaining a molded article that is lightweight and has high mechanical strength, and a molded article obtained therefrom.
熱可塑性樹脂に対して、炭素繊維やガラス繊維のような繊維状充填剤を配合した組成物が汎用されている。 Compositions in which fibrous fillers such as carbon fibers and glass fibers are blended with thermoplastic resins are widely used.
特許文献１には、炭素長繊維強化樹脂ペレットとその製造方法が記載されており、特許文献２には、熱可塑性樹脂、炭素長繊維、ガラス長繊維を含む導電性長繊維複合材が記載されている。これらは、いずれも長繊維のみを配合したものである。 Patent Document 1 describes a carbon long fiber reinforced resin pellet and a production method thereof, and Patent Document 2 describes a conductive long fiber composite material including a thermoplastic resin, a carbon long fiber, and a glass long fiber. ing. These are all blended only with long fibers.
特許文献３には、長繊維炭素繊維強化樹脂ペレットと、ガラス繊維を含む短繊維ガラス繊維強化熱可塑性樹脂ペレットを含む樹脂組成物が記載されており、異なる材質からなる長繊維と短繊維の組み合わせが開示されている。 Patent Document 3 describes a resin composition containing long fiber carbon fiber reinforced resin pellets and short fiber glass fiber reinforced thermoplastic resin pellets containing glass fibers, and a combination of long fibers and short fibers made of different materials. Is disclosed.
特許文献４には、（Ａ）ペレットと実質的に同一長さの強化繊維を含む長繊維強化熱可塑性樹脂ペレット、（Ｂ）重量平均繊維長が０．０１〜０．５ｍｍの強化繊維を含む短繊維強化熱可塑性樹脂ペレット、（Ｃ）難燃剤を含む成形用繊維強化難燃樹脂混合物が記載されている。実施例（表１）では、（Ａ）成分として長繊維（炭素繊維）を含むポリアミド樹脂ペレット、（Ｂ）成分として短繊維（炭素繊維）を含むポリアミド樹脂ペレットを用いた実施例が示されている。しかし、（Ａ）及び（Ｂ）成分を含む実施例１〜３と、（Ａ）成分のみの比較例１を対比すると、比較例１の方が流動性は低下しているが、引張強度は大きくなっており、衝撃強度も同程度である。 Patent Document 4 includes (A) a long fiber reinforced thermoplastic resin pellet containing reinforcing fibers having substantially the same length as the pellet, and (B) a reinforcing fiber having a weight average fiber length of 0.01 to 0.5 mm. Short fiber reinforced thermoplastic resin pellets and (C) a fiber reinforced flame retardant resin mixture for molding containing a flame retardant are described. Examples (Table 1) show examples using polyamide resin pellets containing long fibers (carbon fibers) as component (A) and polyamide resin pellets containing short fibers (carbon fibers) as component (B). Yes. However, when Examples 1 to 3 containing the components (A) and (B) are compared with Comparative Example 1 containing only the component (A), the fluidity is lower in Comparative Example 1, but the tensile strength is It is larger and the impact strength is comparable.
長繊維を含有した場合に流動性が低下し、長繊維に代えて短繊維を含有した場合に流動性が高くなるのは自明のことであるから、特許文献４では、炭素繊維からなる長繊維と短繊維を組み合わせたことによる効果は、流動性の改善という自明の効果と、引張強度や衝撃強度の低下が小さいという消極的効果である。 Since it is obvious that the fluidity decreases when long fibers are contained, and the fluidity increases when short fibers are contained instead of long fibers, in Patent Document 4, long fibers made of carbon fibers are used. The effect of combining the short fiber with the obvious effect is the obvious effect of improving the fluidity and the negative effect that the decrease in tensile strength and impact strength is small.
本発明は、軽量で、引張強度や衝撃強度等の機械的強度が高められた成形体が得られる、プロピレン系樹脂組成物とそれから得られる成形体を提供することを課題とする。 An object of the present invention is to provide a propylene-based resin composition and a molded body obtained therefrom, which are lightweight and obtain a molded body having improved mechanical strength such as tensile strength and impact strength.

In addition to paragraph No. 23 of Japanese Patent Publication No. 6-2344 (Manufacturing method and molding method of resin-coated long fiber bundle), JP-A-6-114732 (Fiber-reinforced thermoplastic resin structure and manufacturing method thereof) JP-A-6-293023 (manufacturing method of long fiber-reinforced thermoplastic resin composition), JP-A-7-205317 (method of taking out fiber bundle and manufacturing method of long fiber-reinforced resin structure), JP-A-7 No. -216104 (manufacturing method of long fiber reinforced resin structure), Japanese Patent Laid-Open No. 7-251437 (manufacturing method and manufacturing apparatus of long fiber reinforced thermoplastic composite material), It can be applied to the manufacturing method described in such as 118490 JP (manufacturing method of the cross-head die and the long-fiber-reinforced resin structures).

〔混合物（Ｂ）〕
混合物（Ｂ）は、平均繊維長が０．０１〜２ｍｍの炭素短繊維とプロピレン系樹脂との混合物である。
[Mixture (B)]

なお、混合物（Ｂ）を前記ペレットにした場合には、次の方法により、平均繊維長を求める。ペレット中のプロピレン系樹脂を溶剤による溶解により除去し、炭素短繊維を取り出す。次に、光学又は電子顕微鏡観察を実施し、炭素短繊維の繊維長をn=1000個測定し、その測定結果から、重量平均繊維長を平均繊維長として評価する。 In addition, when a mixture (B) is made into the said pellet, average fiber length is calculated | required with the following method. The propylene-based resin in the pellet is removed by dissolution with a solvent, and the short carbon fiber is taken out. Next, observation with an optical or electron microscope is carried out, and the fiber length of short carbon fibers is measured at n = 1000. From the measurement results, the weight average fiber length is evaluated as the average fiber length.
