表1に示す配合成分のうち可塑剤(トリメリット酸エステル及びエポキシ化大豆油)とダスティング剤である塩化ビニル樹脂微粒子とを除く成分をヘンシェルミキサーに入れて混合した。そして、混合物の温度が80℃に上昇した時点で可塑剤を添加し、さらに昇温することによりドライアップ(可塑剤が塩化ビニル樹脂粒子に吸収されて、上記混合物がさらさらになった状態をいう。)させた。その後、ドライアップさせた混合物が100℃以下に冷却された時点でダスティング剤である塩化ビニル樹脂微粒子を添加し、粉体成形用塩化ビニル樹脂組成物を調製した。
そして、得られた粉体成形用塩化ビニル樹脂組成物を250℃に加熱したシボ付き金型に振りかけ、塩化ビニル樹脂成形シートの厚みが1mmになるよう調整した時間(具体的には8~20秒間)放置して溶融させた後、余剰の塩化ビニル樹脂組成物を振り落とした。その後、200℃に設定したオーブンに静置し、60秒経過した時点で金型を冷却水により冷却し、金型温度が40℃まで冷却された時点で150mm×200mm×1mmの塩化ビニル樹脂成形シート(塩化ビニル樹脂層)を金型から脱型した。その後、得られた塩化ビニル樹脂成形シートの表面(シボ付き面とは反対側の面)の一部に表2に示す構造のテープを積層して自動車インスツルメントパネル用積層体を得た。
次に、200mm×300mm×10mmの金型の下に250mm×340mm×2mmのアルミ板を置き、テープを積層した塩化ビニル樹脂成形シート(自動車インスツルメントパネル用積層体)2枚を、348mm×255mm×10mmの金型の蓋に、シボ付き面が蓋側になるように、それぞれ接着させた。また、プロピレングリコールのPO(プロピレンオキサイド)・EO(エチレンオキサイド)ブロック付加物(水酸基価28、末端EO単位の含有量=10%、内部EO単位の含有量4%)50質量部、グリセリンのPO・EOブロック付加物(水酸基価21、末端EO単位の含有量=14%)50質量部、水2.5質量部、トリエチレンジアミンのエチレングリコール溶液(東ソー(株)製、商品名:「TEDA-L33」)0.2質量部、トリエタノールアミン1.2質量部、トリエチルアミン0.5質量部及び整泡剤(信越化学工業(株)製、商品名:「F-122」)0.5質量部からなるポリオール混合物と、ポリメチレンポリフェニレンポリイソシアネート(ポリメリックMDI)とを、インデックスが98になる比率で混合して混合液を作製した。次に、得られた混合液を金型に注ぎ、前記塩化ビニル樹脂成形シートを接着させた蓋で、金型を密閉した。5分後、1mm厚の塩化ビニル樹脂成形シートからなる表皮に9mm厚、密度0.18g/cm3の発泡ポリウレタン成形体が裏打ちされた試料(テープが積層された塩化ビニル樹脂成形シート/発泡ポリウレタン成形体/アルミ板積層体)を金型から取り出し、下記の耐熱試験を実施した。結果を表2に示す。
上記試料を130℃に設定されたオーブンに入れた。そして、100時間毎に試料を取り出し、室温まで冷却した後、試験者5名が外観を目視で確認し、次の3段階で評価した。
優:試験者5名のうち5名がテープの跡が現れていないと判断した。
良:試験者5名のうち3名以上4名以下がテープの跡が現れていないと判断した。
