Description
本発明は、プロピレン系樹脂組成物に関し、詳しくは、フィラーを添加せずとも高い剛性が発現できる高外観性に優れた材料で、高光沢、成形性、バリア性、さらには耐薬品性に優れたプロピレン系樹脂組成物に関する。 The present invention relates to a propylene resin composition, and more specifically, it is a material with excellent appearance that can exhibit high rigidity without adding fillers, and has high gloss, moldability, barrier properties, and excellent chemical resistance. The present invention relates to a propylene-based resin composition.
ポリプロピレンは、一般に耐薬品性、特に酸や塩基に対して優れており、また、水蒸気バリア性も良いことが知られており、各種の化粧品容器等の容器やそれを構成する関連部品に使用されている。
化粧品容器においては、化粧品の長期保存に耐え得るような特性や、機械的な物性面で、より高い剛性が求められることもあり、更に化粧品容器においては、イメージ商品としての側面もあるところから、消費者に訴えるような外観、とくに美観及び高級感を有していることが重要である（例えば、特許文献１を参照。）。ポリプロピレン系樹脂組成物に高い剛性を付与させる手法としては、タルクなどのフィラーを添加する方法が挙げられるが、製品の光沢は低下し、意匠性が損なわれる場合がある。意匠性を維持しつつ、市場より要望されるより高い剛性を保持できるポリプロピレン系樹脂組成物及び各種の化粧品容器等の容器やそれを構成する関連部品は提供されていなかった。
Polypropylene generally has excellent chemical resistance, especially against acids and bases, and is also known to have good water vapor barrier properties, and is used for various cosmetic containers and related parts. ing.
Cosmetic containers require higher rigidity in terms of mechanical properties and characteristics that allow cosmetics to withstand long-term storage.Furthermore, cosmetic containers also have the aspect of being an image product. It is important to have an appearance that appeals to consumers, especially beauty and luxury (see, for example, Patent Document 1). One method for imparting high rigidity to a polypropylene resin composition is to add a filler such as talc, but this may reduce the gloss of the product and impair its design. Polypropylene resin compositions, containers such as various cosmetic containers, and related parts constituting the same have not been provided, which can maintain a higher rigidity than required by the market while maintaining design.
本発明の目的は、上記問題点に鑑み、プロピレン系樹脂組成物に関し、詳しくは、フィラーを添加せずとも高い剛性が発現できる高外観性に優れた材料で、高光沢、成形性、バリア性、さらには耐薬品性に優れたプロピレン系樹脂組成物を提供することにある。 In view of the above-mentioned problems, the object of the present invention is to provide a propylene-based resin composition, in particular, a material with excellent appearance that can exhibit high rigidity without adding fillers, high gloss, moldability, and barrier properties. Another object of the present invention is to provide a propylene resin composition having excellent chemical resistance.
本発明者は、上記課題を解決するために鋭意研究の結果、特定のプロピレン系重合体２種を基材とし特定の造核剤を含有するプロピレン系樹脂組成物は、フィラーを添加せずとも高い剛性が発現できる高外観性に優れた材料で、高光沢、成形性、バリア性、さらには耐薬品性に優れ化粧品容器やそれを構成する関連部品として好適であることを見出し、本発明を完成するに至った。 As a result of intensive research to solve the above problems, the present inventors have discovered that a propylene resin composition containing two specific propylene polymers as a base material and a specific nucleating agent can be produced without adding a filler. We have discovered that this material is a material that can exhibit high rigidity and has an excellent appearance, and has high gloss, moldability, barrier properties, and chemical resistance, making it suitable for cosmetic containers and related parts that constitute them. It has been completed.
すなわち、本発明は、以下のプロピレン系樹脂組成物及び成形品を提供するもので、特に、フィラーを添加せずとも高い剛性が発現できる高外観性に優れたプロピレン系樹脂組成物及び成形品として主に化粧品容器やそれを構成する関連部品を提供するものである。 That is, the present invention provides the following propylene-based resin compositions and molded articles, and in particular, as propylene-based resin compositions and molded articles that exhibit high rigidity and excellent appearance without the addition of fillers.

表２から明らかなように、実施例１～３は、本発明のプロピレン系樹脂組成物（Ｄ）を用いたものであり、高剛性で高光沢、外観に優れた材料であることが判る。比較例１は、本発明の造核剤（Ｃ）を用いたものであるが、プロピレン単独重合体（Ｂ）のみのため、剛性が十分ではないことが判る。比較例２は、造核剤を使用しなかったもので、剛性が十分ではないことが判る。比較例３はフィラーとしてタルクを添加し剛性を向上させたもので、高い剛性が得られるが、一方で、フィラーの影響で光沢が下がり、意匠性が悪くなることが判る。比較例４は、分子量調整剤でＭＦＲを調整し、プロピレン単独重合体（Ｂ）相当に本発明とは異なる造核剤を用いたもので、剛性が不十分であることが判る。比較例５は、本発明のプロピレン単独重合体（Ａ）とプロピレン単独重合体（Ｂ）を用いているが、本発明とは異なる造核剤を用いたもので、剛性が不十分であることが判る。また、比較例６は、本発明のプロピレン単独重合体（Ａ）とプロピレン単独重合体（Ｂ）を用いているが、造核剤を使用していないもので、剛性が不十分であることが判る。比較例７は、ＭＦＲ２／ＭＦＲ１が５００を超えるもので、外観不良が発生することが判る。
また、表３は、３成分併用による相乗効果を確認した結果で、本発明とは異なる造核剤を用いた比較例１５より、本発明の実施例４の方が優れていることが判る。
As is clear from Table 2, Examples 1 to 3 used the propylene resin composition (D) of the present invention, and it can be seen that the material is highly rigid, has high gloss, and has excellent appearance. Comparative Example 1 uses the nucleating agent (C) of the present invention, but it can be seen that the rigidity is not sufficient because it is made only of propylene homopolymer (B). In Comparative Example 2, no nucleating agent was used, and it can be seen that the rigidity was not sufficient. In Comparative Example 3, talc was added as a filler to improve rigidity, and high rigidity was obtained, but on the other hand, it was found that the gloss decreased due to the influence of the filler and the design deteriorated. In Comparative Example 4, the MFR was adjusted with a molecular weight regulator and a nucleating agent different from that of the present invention was used for the propylene homopolymer (B), and it was found that the rigidity was insufficient. Comparative Example 5 uses the propylene homopolymer (A) and propylene homopolymer (B) of the present invention, but uses a nucleating agent different from that of the present invention, so the rigidity is insufficient. I understand. In addition, Comparative Example 6 uses the propylene homopolymer (A) and propylene homopolymer (B) of the present invention, but does not use a nucleating agent, so the rigidity may be insufficient. I understand. In Comparative Example 7, MFR2/MFR1 exceeds 500, and it can be seen that poor appearance occurs.
Further, Table 3 shows the results of confirming the synergistic effect of the combination of the three components, and it can be seen that Example 4 of the present invention is superior to Comparative Example 15 using a nucleating agent different from that of the present invention.
