Description
本発明は、耐汚れ性に優れたポリプロピレン樹脂組成物に関し、特に、耐汚れ性、物性バランスに優れ、かつ射出成形加工性が良好なポリプロピレン樹脂組成物に関する。 The present invention relates to a polypropylene resin composition excellent in stain resistance, and particularly relates to a polypropylene resin composition excellent in stain resistance and physical property balance and excellent in injection molding processability.
従来からポリプロピレンなどのポリオレフィンは、たとえば射出成形により部品などに成形され、各種用途に広く利用されている。このようなポリプロピレン成形品は、意匠性、耐傷つき性向上などのために通常部品表面に塗装が施されている。しかしながら、近年は、コスト合理化の観点から、また溶剤規制などの環境問題の観点から、樹脂に直接顔料を入れ着色することにより塗装を施さない、いわゆる原着材料としての使用が広がってきている。 Conventionally, polyolefins such as polypropylene have been molded into parts and the like by, for example, injection molding, and are widely used in various applications. Such a polypropylene molded article is usually coated on the surface of a part in order to improve design properties and scratch resistance. However, in recent years, from the viewpoint of cost rationalization and from the viewpoint of environmental problems such as solvent regulations, the use as a so-called original material, in which coating is not performed by directly pigmenting and coloring a resin, has been spreading.
例えば、プロピレン系樹脂；５０〜９５重量部と、アクリル系樹脂；５〜４０重量部とからなる樹脂成分と着色剤、無機充填剤とから形成された原着材料からなる表面光沢に優れ、色の深みがある塗装不要な射出成形品（例えば、特許文献１参照。）が提案されている。また、プロピレン系ブロック共重合体５０〜９９．９重量％、ポリエチレン０．１〜１０重量％、ＭＦＲが０．１〜６０ｇ／１０分のエチレン−α−オレフィン共重合体エラストマー又はスチレン系エラストマー０〜３０重量％、無機フィラー０〜５０重量％、脂肪酸アミド又はその誘導体０．０５〜３重量部、２５℃における粘度が１万ｍｍ２／ｓ以上のシリコーン化合物０〜３重量部、不飽和カルボン酸又はその誘導体で変性されたポリオレフィン０〜５重量部からなる耐傷つき性の良好な原着材料（例えば、特許文献２参照。）が提案されている。 For example, it has excellent surface gloss composed of a raw material formed from a resin component consisting of a propylene-based resin; 50 to 95 parts by weight and an acrylic resin; 5 to 40 parts by weight, a colorant, and an inorganic filler. There has been proposed an injection-molded product (see, for example, Patent Document 1) that does not require painting. Also, an ethylene-α-olefin copolymer elastomer or a styrene elastomer 0 to 50 to 99.9% by weight of a propylene-based block copolymer, 0.1 to 10% by weight of polyethylene, and 0.1 to 60 g / 10 min of MFR -30% by weight, inorganic filler 0-50% by weight, fatty acid amide or derivative 0.05-3 parts by weight, silicone compound 0-25 parts by weight with a viscosity at 25 ° C. of 10,000 mm 2 / s or more, unsaturated carboxylic acid An original material having good scratch resistance composed of 0 to 5 parts by weight of a polyolefin modified with an acid or a derivative thereof (for example, see Patent Document 2) has been proposed.
しかし、かかる提案では、雨水、油、埃、ダスト、虫などによる汚れ成分に対する考慮は一切なされていない。長期における屋内外での使用においては、成形品表面に前記汚れ成分に起因するしみ等の汚れが付着するといった問題が想定される。付着した汚れが落ちやすい耐汚れ性に優れた原着材料が出現すれば産業上利用価値はきわめて大きい。本発明者らの検討では、上記提案にかかる原着材料は、使用態様を想定した汚れ試験において付着した汚れが落ちにくく、耐汚れ性の性能が十分なものとはいえなかった。
本発明の目的は、上記欠点を解決しつつ、耐汚れ性に優れているポリプロピレン樹脂組成物を提供、特に成形性、物性バランスに優れ、その上耐汚れ性に優れているポリプロピレン樹脂組成物を提供することにある。 The object of the present invention is to provide a polypropylene resin composition excellent in stain resistance while solving the above-mentioned drawbacks, and in particular, a polypropylene resin composition excellent in moldability and physical property balance and excellent in stain resistance. It is to provide.
本発明者等は、上記課題を解決するために、種々の研究を重ねた結果、ポリプロピレン樹脂に特定のエチレン・エチルアクリレート共重合体（ＥＥＡ）並びに脂肪酸アミド類を組み合わせることにより、成形性、物性バランスに優れ、特に従来の材料に比べて耐汚れ性を発現することを見出し、本発明を完成することに至ったものである。 In order to solve the above problems, the present inventors have made various studies, and as a result, by combining a specific ethylene / ethyl acrylate copolymer (EEA) and fatty acid amides with polypropylene resin, moldability and physical properties are improved. It has been found that it is excellent in balance and particularly exhibits stain resistance as compared with conventional materials, and the present invention has been completed.

１．ポリプロピレン樹脂組成物の構成成分
（１）ポリプロピレン樹脂（Ａ）
本発明のポリプロピレン樹脂組成物に用いるポリプロピレン樹脂（Ａ）は、プロピレン単独重合体、プロピレンと炭素数２〜１０のプロピレン以外のα−オレフィンとの共重合体、例えば、プロピレン・α−オレフィンランダム共重合体、プロピレン・α−オレフィンブロック共重合体などから選ばれる樹脂である。共重合体に用いるα−オレフィンとしては、例えば、エチレン、１−ブテン、１−ヘキセン、４−メチル−１−ペンテン、１−オクテンなどから選ばれ、なかでも、エチレン、１−ブテン、１−ヘキセンが好ましく、特にエチレンが好ましい。
1. Component of polypropylene resin composition (1) Polypropylene resin (A)
The polypropylene resin (A) used in the polypropylene resin composition of the present invention is a propylene homopolymer, a copolymer of propylene and an α-olefin other than propylene having 2 to 10 carbon atoms, such as propylene / α-olefin random copolymer. It is a resin selected from a polymer, a propylene / α-olefin block copolymer, and the like. The α-olefin used in the copolymer is, for example, selected from ethylene, 1-butene, 1-hexene, 4-methyl-1-pentene, 1-octene, and the like. Among them, ethylene, 1-butene, 1-octene Hexene is preferred, and ethylene is particularly preferred.
ポリプロピレン樹脂（Ａ）のメルトフローレート（ＭＦＲ）は、１０〜２００ｇ／１０分が好ましく、３０〜１５０ｇ／１０分がより好ましく、５０〜１２０ｇ／１０分がさらに好ましい。ＭＦＲが１０ｇ／１０分未満では成形性が劣り、２００ｇ／１０分を超えると衝撃強度、引張り伸びが低下する。
ここで、ＭＦＲは、ＪＩＳ Ｋ ７２１０に準拠し、２３０℃、２．１６ｋｇ荷重で測定する値である。
The melt flow rate (MFR) of the polypropylene resin (A) is preferably 10 to 200 g / 10 minutes, more preferably 30 to 150 g / 10 minutes, and further preferably 50 to 120 g / 10 minutes. When the MFR is less than 10 g / 10 minutes, the moldability is inferior, and when it exceeds 200 g / 10 minutes, the impact strength and the tensile elongation are lowered.
Here, MFR is a value measured at 230 ° C. and a 2.16 kg load in accordance with JIS K 7210.
ポリプロピレン樹脂（Ａ）が、プロピレンとα−オレフィンランダム共重合体である場合、共重合体中のα−オレフィン含量は、０．１〜２０重量％が好ましく、０．５〜１２重量％がより好ましく、１〜８重量％がさらに好ましい。 When the polypropylene resin (A) is propylene and an α-olefin random copolymer, the α-olefin content in the copolymer is preferably 0.1 to 20% by weight, more preferably 0.5 to 12% by weight. Preferably, 1 to 8% by weight is more preferable.
ポリプロピレン樹脂（Ａ）が、プロピレン単独重合体部分である結晶性ポリプロピレン部分とプロピレン・α−オレフィン共重合体部分からなるプロピレン・α−オレフィンブロック共重合体である場合、プロピレン・α−オレフィン共重合体部分の含有量は、２〜３５重量％が好ましく、プロピレン・α−オレフィン共重合体部分のα−オレフィン含有量は、７０重量％以下が好ましく、３０〜６０重量％がより好ましい。また、結晶性ポリプロピレン部分のＭＦＲは、３０〜４００ｇ／１０分が好ましく、５０〜３００ｇ／１０分がより好ましく、１００〜２００ｇ／１０分がさらに好ましい。結晶性ポリプロピレン部分のＭＦＲとブロック共重合体全体のＭＦＲの組合せが上記範囲を逸脱した場合、流動性や耐衝撃性、引張伸びが不良となる。 When the polypropylene resin (A) is a propylene / α-olefin block copolymer comprising a crystalline polypropylene portion which is a propylene homopolymer portion and a propylene / α-olefin copolymer portion, propylene / α-olefin copolymer The content of the coalescence part is preferably 2 to 35% by weight, and the content of the α-olefin in the propylene / α-olefin copolymer part is preferably 70% by weight or less, more preferably 30 to 60% by weight. The MFR of the crystalline polypropylene portion is preferably 30 to 400 g / 10 minutes, more preferably 50 to 300 g / 10 minutes, and further preferably 100 to 200 g / 10 minutes. When the combination of the MFR of the crystalline polypropylene portion and the MFR of the entire block copolymer is out of the above range, fluidity, impact resistance, and tensile elongation become poor.
ポリプロピレン樹脂（Ａ）は、高立体規則性触媒を用いてスラリー重合、バルク重合、気相重合により製造することが好ましい。高立体規則性触媒としては、塩化マグネシウムに四塩化チタン、有機ハイドライド、及び有機シラン化合物を接触させて形成した固体成分に有機アルミニウム化合物を組み合わせた触媒が挙げられる。重合方式としては、バッチ重合、連続重合のどちらの方式でも採用される。 The polypropylene resin (A) is preferably produced by slurry polymerization, bulk polymerization, or gas phase polymerization using a highly stereoregular catalyst. Examples of the highly stereoregular catalyst include a catalyst in which an organic aluminum compound is combined with a solid component formed by bringing magnesium chloride into contact with titanium tetrachloride, an organic hydride, and an organic silane compound. As the polymerization method, either batch polymerization or continuous polymerization can be employed.
（２）エチレン・エチルアクリレート共重合体（Ｂ）
本発明のポリプロピレン樹脂組成物に用いるエチレン・エチルアクリレート共重合体（Ｂ）は、エチルアクリレート重合単位の比率が５〜５０重量％であり、７〜３０重量％が好ましく、１０〜２０重量％が特に好ましい。エチルアクリレート重合単位の比率が５重量％未満であると耐汚れ性が劣り、５０重量％を超えると耐熱性、剛性が低下したり、層状剥離等の成形品の外観不良が発生したりするので好ましくない。
(2) Ethylene / ethyl acrylate copolymer (B)

Particularly preferred. If the ratio of the ethyl acrylate polymerization unit is less than 5% by weight, the stain resistance is inferior, and if it exceeds 50% by weight, the heat resistance and rigidity are deteriorated or the appearance of the molded product such as delamination is deteriorated. It is not preferable.
また、エチレン・エチルアクリレート共重合体（Ｂ）は、メルトインデックス（１９０℃、２．１６ｋｇ荷重で測定）の値が１〜１２０ｇ／１０分が好ましく、１０〜１００ｇ／１０分がより好ましく、２０〜８０ｇ／１０分がさらに好ましい。メルトインデックスがこの範囲にあると、耐汚れ性がより向上するので好ましい。
ここで、メルトインデックスは、ＪＩＳ−Ｋ７２１０に準拠し、１９０℃、２．１６ｋｇ荷重で測定する値である。
The ethylene / ethyl acrylate copolymer (B) preferably has a melt index (measured at 190 ° C. under a load of 2.16 kg) of 1 to 120 g / 10 minutes, more preferably 10 to 100 g / 10 minutes, More preferred is -80 g / 10 min. When the melt index is within this range, the stain resistance is further improved, which is preferable.
Here, the melt index is a value measured according to JIS-K7210 at 190 ° C. and a 2.16 kg load.
