Description
ハロゲン化ベンゼンと、アルカリ金属硫化物との重縮合体であり、
ハロゲン化ベンゼンが、ジハロベンゼン及び/又はトリハロベンゼンであり、
ハロゲン化ベンゼンの質量に対するトリハロベンゼンの質量の比率が50質量%以上であり、
ハロゲン化ベンゼンがフッ素原子、塩素原子、臭素原子、及びヨウ素原子からなる群より選択される1種~3種のハロゲン原子を有する。
ハロゲン化ポリフェニレンスルフィド樹脂は、ハロゲン化ベンゼンと、アルカリ金属硫化物との重縮合体である。ハロゲン化ベンゼンは、ジハロベンゼン及び/又はトリハロベンゼンである。ハロゲン化ベンゼンの質量に対するトリハロベンゼンの質量の比率が50質量%以上である。
ハロゲン化ベンゼンは、フッ素原子、塩素原子、臭素原子、及びヨウ素原子からなる群より選択される1種~3種のハロゲン原子を有する。
ハロゲン化ベンゼンにおけるハロゲン原子としては、ハロゲン化ハロベンゼンの重縮合の反応性や、ハロゲン化ハロベンゼンの入手の容易性の点から塩素原子が好ましい。つまり、ハロゲン化ベンゼンとしては、ジクロロベンゼン、及びトリクロロベンゼンが好ましい。
トリハロベンゼンが1,2,4-トリクロロベンゼンを含む場合の、トリハロベンゼンの質量に対する1,2,4-トリクロロベンゼンの質量の比率は70質量%以上が好ましく、80質量%以上がより好ましく、90質量%以上がさらに好ましく、95質量%以上がさらにより好ましく、100質量%が最も好ましい。
なお、製造方法によっては、トリハロベンゼンが、不純物としてジハロベンゼンを含む場合がある。このような、ジハロベンゼンを不純物として含むトリハロベンゼンを、ハロゲン化ポリフェニレンスルフィドの原料として好ましく用いることができる。
この場合、ジハロベンゼンを不純物として含むトリハロベンゼンにおける、トリハロベンゼンの純度が90質量%以上99.9質量%以下であり、ジハロベンゼンの含有量が0.1質量%以上10%以下であるのが好ましく、トリハロベンゼンの純度が95質量%以上99.9質量%以下であり、ジハロベンゼンの含有量が0.1質量%以上5質量%以下であるのがより好ましい。
好ましい方法としては、ハロゲン化ベンゼンとアルカリ金属硫化物とを、溶媒の存在下に加熱して重合させる方法が挙げられる。
ハロゲン化ベンゼンの使用量は、硫黄源としてのアルカリ金属硫化物の仕込み量1モルに対し、好ましくは1.30モル以上1.90モル以下であり、より好ましくは1.40モル以上1.80モル以下であり、さらにより好ましくは1.50モル以上1.70モル以下である。上記の量のトリハロベンゼンを用いることにより、所望する程度に高分子量化したハロゲン化ポリフェニレンスルフィド樹脂を得やすい。
硫黄源をアルカリ金属水酸化物の存在下にトリハロベンゼンと反応させる方法が、諸特性バランスの良好なハロゲン化ポリフェニレンスルフィド樹脂を得るのに適していることが判明している。
アルカリ金属水酸化物の使用量は、本発明の目的を阻害しない範囲で特に限定されない。アルカリ金属水酸化物の使用量は、典型的には、硫黄源としてのアルカリ金属硫化物1モルに対して0.01モル以上0.1モル以下が好ましく、0.03モル以上0.08モル以下がより好ましい。
水の使用量は、本発明の目的を阻害しない範囲で特に限定されない。水の使用量は、典型的には硫黄源としてのアルカリ金属硫化物1モルに対して1.0モル以上2.5モル以下が好ましく、1.2モル以上2.3モル以下がより好ましい。
重縮合反応はバッチ式で行われてもよく、連続式で行われてもよい。
反応時間は特に限定されず、重縮合反応が所望する程度まで進行する時間が適宜選択される。典型的には、反応時間は0.5時間以上12時間以下が好ましく、1時間以上6時間以下がより好ましい。
典型的には、反応液を例えば0℃以上50℃以下、好ましくは10℃以上40℃以下程度の室温付近の温度まで冷却した後、冷却された反応液に含まれるハロゲン化ポリフェニレンスルフィド樹脂の粗製品を洗浄して回収する。
ハロゲン化ポリフェニレンスルフィド樹脂の粗製品は、公知の方法により洗浄される。洗浄方法としては、アセトン洗浄と、水による洗浄とをこの順で行う方法が挙げられる。この場合、洗浄に用いられるアセトンには、例えば、10質量%以下、好ましくは5質量%以下程度の水を含有させてもよい。アセトン、及び水による洗浄について、ハロゲン化ポリフェニレンスルフィド樹脂を酢酸水溶液により洗浄するのが好ましい。酢酸水溶液の濃度は特に限定されないが、例えば、0.05質量%以上5質量%以下であり、0.1質量%以上2質量%以下であってよい。
上記の洗浄を行う場合の温度条件は、所望する洗浄効果が得られる限り特に限定されない。上記の各洗浄操作を実施する温度は、例えば、0℃以上80℃以下であってよく、10℃以上60以下であってよく20℃以上50℃以下であってよい。
以上説明したハロゲン化ポリフェニレンスルフィド樹脂は、好ましくは、ハロゲン化ポリフェニレンスルフィド樹脂以外の他の樹脂と混合されて使用される。ハロゲン化ポリフェニレンスルフィド樹脂を、他の樹脂と混合して使用することにより、他の樹脂の制振性を向上させることができる。
硬化性樹脂と、ハロゲン化ポリフェニレンスルフィド樹脂とを混合する方法としては、粉末又は粒子状のハロゲン化ポリフェニレンスルフィド樹脂を、液状又は溶液状の未硬化の状態の硬化性樹脂の前駆体と混合させ、混合後、必要に応じて溶媒を除去する方法が挙げられる。この場合、硬化性樹脂の種類に応じて、混合物に、硬化剤を配合してもよい。
以上のようにして得られる混合物は、硬化性樹脂の種類に応じた方法で、加熱及び/又は露光により硬化され樹脂組成物とされる。
また、制振性に優れる樹脂組成物を得やすい点で、ポリフェニレンスルフィド樹脂は、p-フェニレンスルフィド樹脂と、ポリm-フェニレンスルフィド樹脂との組み合わせであるのもの好ましい。ポリm-フェニレンスルフィド樹脂は、典型的には、m-ジクロロベンゼンとスルフィド化剤(例えば、アルカリ金属硫化物やアルカリ金属水硫化物)との重縮合物である。
ポリアリーレンスルフィド樹脂としては特に限定されず、従来知られるポリアリーレンスルフィド樹脂から適宜選択され得る。ハロゲン化ポリフェニレンスルフィド樹脂と配合されるポリアリーレンスルフィド樹脂については、融点が270℃以上300℃以下であるのが好ましく、重量平均分子量(Mw)が1000以上100000以下であるのが好ましく、温度310℃、せん断速度1200sec-1で測定した溶融粘度が100Pa・s以上250Pa・s以下であるのが好ましい。
以上説明した樹脂組成物は、制振材料として好適に使用される。本出願の明細書及び特許請求の範囲において、具体的には、動的粘弾性測定に従って測定される損失係数(tanδ)として0.150以上の値を示す材料を制振材料とする。制振材料の損失係数は、0.170以上が好ましく、0.200以上がより好ましい。
以上説明した樹脂組成物、又は制振材料は、他の樹脂の種類に応じた適切な方法により種々の形状の成形品とされ好適に使用される。
また、未硬化の状態の硬化性樹脂を含む樹脂組成物が液状である場合、3Dプリンティング法により所望する形状の成形品を製造することもできる。この場合、樹脂組成物は、成形途中に適宜硬化されてもよく、所望する形状の成形品を得た後に成形品が硬化されてもよい。
以上説明した用途の中でも、成形品の用途としては、自動車等の内燃機関を備える輸送機におけるクーラント循環装置の部品が挙げられる。かかるクーラント循環装置の部品としては、ポンプ筐体やクーラント循環用のパイプ等が挙げられる。
成形品を上記の用途に用いることにより、各種製品の制振化を図ることができる。
樹脂用の制振化剤は、前述のハロゲン化ポリフェニレンスルフィド樹脂を含む。制振化剤は、ハロゲン化ポリフェニレンスルフィド樹脂のみからなってもよく、ハロゲン化ポリフェニレンスルフィド樹脂と、他の成分とからなってもよい。他の成分としては特に限定されず、着色剤、前述の熱可塑性樹脂、可塑剤、及び相溶化剤等が挙げられる。特に、ハロゲン化ポリフェニレンスルフィド樹脂を、熱可塑性樹脂中に高濃度で混合することにより、制振化剤のマスターバッチとすることができる。マスターバッチには、必要に応じて、可塑剤や、相溶化剤を含めるのが好ましい。
