Description
[イ]熱膨張性マイクロカプセルの平均粒子径が3μm未満では:(甲)目標の比重を得るのに必要な熱膨張性マイクロカプセルの添加量が増え、配合コストが増加する;(乙)また、平均粒子径が小さく膨張後の気泡径を同じ(平均100μm以下)にすると膨張倍率が上がることになり、カプセルの殻壁厚が薄くなる傾向となり、その結果、殻壁の破裂により、内包ガスの放出の可能性が上がり、比重安定性および火脹れ改善に不利となる。
また、グラスランチャンネルへの適用も可能である。

- 取付基部(11)と中空シール部(12)を備える自動車用のウエザーストリップにおいて、前記取付基部(11)は金属製芯材(13)を埋設し、且つ前記取付基部は、平均粒子径:3〜20μm(望ましくは、5〜15μm)、膨張開始温度:110℃〜150℃、最大膨張温度:130〜150℃、殻壁:アクリロニトリル共重合体である熱膨張性マイクロカプセルを所定量混練して、加硫工程で発泡させるにあたり、ゴムが加硫する前の柔らかい状態の時に殻壁を膨張させ、かつ、融点の低い(約150℃以下)殻壁を使用することにより、ゴム加硫炉内で溶融し、表面を均し、平均気泡径:100μm以下の気泡を持ち、粒子径および膨張倍率の小さい熱膨張性マイクロカプセルを用いた微発泡ソリッドゴムで形成されたものであることを特徴とする自動車用ウエザーストリップの製造方法。
