下記のとおり試験体を作製して、実施例1、無塗装、G社塗料、およびS社塗料の試験体の上部に熱を加えた後、試験体の裏面における表面温度を1秒間隔で測定を行うことで、断熱性を確認した。横×縦×厚さが、それぞれ45.5cm×45.5cm×0.35cmである亜鉛塗鋼板の4枚を用意し、それぞれの一面に3種の外壁用塗料を塗布した試験体を作製して、発泡スチロール箱の上面を試験体で覆い、塗料が塗装された面を照明器具に向けて配設した。試験体の上部において照明器によって加熱し、その時の発泡スチロール箱の内部における中心温度と、試験体の裏面(発泡スチロール箱側の非塗布面)に伝わる中心温度を測定した。その時、発泡スチロール箱と試験体との隙間を無くすために、計5.38kgの重さを均等の荷重になるように設け、照明器具は、試験体から27cmの離れた位置に設置した。試験体の裏面の熱電対を設置して、1秒間隔で表面の温度を測定した。
<試験例2−加熱による断熱塗料組成物の断熱性試験>
下記のとおり試験体を作製して、実施例1、無塗装及び通常の断熱塗料組成物の試験体を、100℃に達した加熱済みのフライパン上に乗せて、その上で氷(15g)が完全に溶ける時間を測定することによって断熱性を確認した。横×縦×厚さが、それぞれ7cm×15cm×0.02cmである試験体(錫板)の3枚を用意して、それぞれの一面に該塗料を塗布した試験体を、塗布面が上を向くようにした後、加熱時、氷が試験体の中央から離れないように円形の型の中に入れた。
下記のとおり試験体を作製して、実施例1、無塗装及び通常の断熱塗料組成物の試験体をガスバーナーで加熱して、点火した後、消火までの時間及び試験体の貫通時までの時間を測定して耐火性試験を行った。横×縦×厚さが、それぞれ30cm×30cm×5cmである発泡ウレタンの3枚を用意して、それぞれの一面に該塗料を塗布した試験体の塗布面をガスバーナーで加熱して(約1000℃)、耐火試験を行った。
前記で製造した実施例1、比較例1、2及び通常の断熱塗料に対して、接着力及び屈曲性を測定して比較した。
前記で製造した実施例1及び無塗装に対して、下記のとおり、帯電防止性をさらに測定して比較した。
