Description
表1および表2に示す配合処方において、各成分を配合し、これをミキシングロールで混練することにより、樹脂組成物を混練物として調製した。なお、表中の各成分の配合量は「重量部」を表す。

各実施例および各比較例の外板用補強材の離型紙を剥がし、各外板用補強材を、25mm幅×150mm長さ×0.8mm厚さの冷間圧延鋼板(SPCC−SD)(日本テストパネル社製)の全面に、20℃雰囲気下で貼着し、180℃で20分加熱することにより、樹脂層を発泡硬化させ、試験片を作製した。なお、各外板用補強材の樹脂層の発泡倍率(体積発泡倍率)を表1、表2に示す。発泡倍率は発泡硬化後の試料厚みを発泡硬化前の試料厚みで除する事で求めた。
冷間圧延鋼板(SPCC−SD)(日本テストパネル社製)を、各外板用補強材に対応して用意し、その表面に防錆剤(出光興産社製、ダフニーオイルZ−5)を塗布し、20℃にて一晩垂直に立て掛けた。
