Description
ガラス転移温度以上の温度に保持する時間としては、特に制約はないが、60分以下、さらには20分以下、さらに好ましくは5分以下が好ましい。ガラス転移温度以上の所定の温度になれば速やかに次の操作に移ってもよい。
50mmφ単軸押出し機に、スチレンの架橋していない単独重合体として市販されている発泡性スチレン系樹脂より得られた発泡成形体を減溶、粉砕することで得られたスチレン系樹脂を投入し、加熱溶融した後に小孔を有するダイよりストランド状に押出し、水中で急冷した後にペレタイザーで切断することで円柱状スチレン系樹脂粒子を得た。
サイズは各サンプル中から無作為に20粒を選択し、100分の1ミリメートルまで測定可能なノギスを用いて測定し、数平均値として算出した。
撹拌機を具備した反応器に、純水200重量部、第三リン酸カルシウム0.6重量部、α−オレフィンスルフォン酸ソーダ0.012重量部、食塩1重量部、及び表1に示すサイズの円柱状スチレン系樹脂粒子100重量部を入れ、攪拌下で昇温を開始した。加温された水媒体中で円柱状スチレン系樹脂粒子を熱収縮させる為に、第1昇温としては約1.5℃/分の割合で120℃まで昇温し、続いて95℃まで冷却した後にペンタン(ノルマル80重量%、イソ20重量%混合品)6重量部を加えた。
表1に示すサイズの円柱状スチレン系樹脂粒子を用い、第1昇温としては約1.5℃/分の割合で110℃まで昇温した後に95℃まで冷却してペンタンを加えた以外は実施例1と同様にして発泡性スチレン系樹脂粒子を得て、表2に示す結果を得た。
表1に示すサイズの円柱状スチレン系樹脂粒子を用い、第1昇温としては約1.5℃/分の割合で120℃まで昇温した後に95℃まで冷却してペンタンを加えた以外は実施例1と同様にして発泡性スチレン系樹脂粒子を得て、表2に示す結果を得た。
表1に示すサイズの円柱状スチレン系樹脂粒子を用い、第1昇温としては約1.5℃/分の割合で105℃まで昇温した後に95℃まで冷却してペンタンを加えた以外は実施例1と同様にして発泡性スチレン系樹脂粒子を得て、表2に示す結果を得た。
表1に示すサイズの円柱状スチレン系樹脂粒子を用い、第1昇温としては約1.5℃/分の割合で120℃まで昇温し、更に3時間保持した後に95℃まで冷却してペンタンを加えた以外は実施例1と同様にして発泡性スチレン系樹脂粒子を得て、表2に示す結果を得た。
表1に示すサイズの円柱状スチレン系樹脂粒子を用い、第1昇温としては約1.5℃/分の割合で95℃まで昇温した後に、直ちにペンタンを加えた以外は、実施例1と同様にして発泡性スチレン系樹脂粒子を得て、表2に示す結果を得た。
Claims (3)
- スチレン系樹脂を溶融、混練後に造粒することにより得られる円柱状スチレン系樹脂粒子を水性媒体中に分散させ、発泡剤を含浸させる発泡性スチレン系樹脂粒子の製造方法であって、円柱状スチレン系樹脂粒子の長さ方向を5%以上50%以下になるまで熱収縮させた後に発泡剤を添加、含浸させることを特徴とする、発泡性スチレン系樹脂粒子の製造方法。
- 前記熱収縮前の円柱状スチレン系樹脂粒子が、長さ/直径の比率が0.8以上3.0以下であることを特徴とする、請求項1記載の発泡性スチレン系樹脂粒子の製造方法。
- 前記スチレン系樹脂が、50重量%以上の回収された再利用スチレン系樹脂を含んでいることを特徴とする、請求項1または2に記載の発泡性スチレン系樹脂粒子の製造方法。
