2.熱膨張性を有する被覆材であって、
結合剤、耐熱性付与剤、充填剤、及び溶剤を含む液状またはゲル状の粒子が、水性媒体に分散しており、
上記液状またはゲル状の粒子が、
上記耐熱性付与剤として難燃剤を含む第1粒子、並びに
上記耐熱性付与剤として発泡剤を含む第2粒子
を含むことを特徴とする被覆材。
3.上記水性媒体が、炭化剤を含むことを特徴とする1.または2.記載の被覆材。
4.上記水性媒体が、発泡剤を含むことを特徴とする1.〜3.のいずれかに記載の被覆材。
結合剤(A)、耐熱性付与剤(B)、充填剤(C)、及び溶剤(D)を含む液状またはゲル状粒子が、水性媒体に分散しており、上記耐熱性付与剤(B)として、難燃剤(B1)及び/または発泡剤(B2)を含むことを特徴とする。
・結合剤:溶剤可溶形アクリル樹脂(固形分50重量%、ミネラルスピリット溶液)
・難燃剤:ポリリン酸アンモニウム
・発泡剤:メラミン
・炭化剤:ジペンタエリスリトール
・充填剤:酸化チタン
・溶剤:ミネラルスピリット
・水性媒体:カチオン性ポリビニルアルコール3重量%水溶液
(熱膨張性組成物1)
結合剤200重量部(固形分100重量部)に、難燃剤380重量部、発泡剤75重量部、充填剤90重量部、炭化剤90重量部、溶剤100重量部を加えて均一に混合し、熱膨張性組成物1を製造した。
結合剤200重量部(固形分100重量部)に、難燃剤380重量部、発泡剤75重量部、充填剤90重量部、溶剤80重量部を加えて均一に混合し、熱膨張性組成物2を製造した。
結合剤200重量部(固形分100重量部)に、難燃剤380重量部、充填剤90重量部、炭化剤90重量部、溶剤80重量部を加えて均一に混合し、熱膨張性組成物3を製造した。
結合剤200重量部(固形分100重量部)に対し、発泡剤75重量部、充填剤90重量部、炭化剤90重量部を加えて均一に混合し、熱膨張性組成物4を製造した。
(被覆材1)
水性媒体を攪拌しながら、熱膨張性組成物1を分散させた後に、架橋剤(有機チタネート化合物)を混合することにより、熱膨張性組成物1の液状粒子が水性媒体に分散してなる被覆材1を製造した。
熱膨張性組成物1を熱膨張性組成物2に代えた以外は、被覆材1と同様にして被覆材を製造し、この被覆材に炭化剤を混合(被覆材1の結合剤100重量部に対し90重量部の比率)することにより、熱膨張性組成物2の液状粒子が、炭化剤を含む水性媒体に分散してなる被覆材2を得た。
熱膨張性組成物1を熱膨張性組成物3に代えた以外は、被覆材1と同様にして被覆材3−1を製造した。次に、熱膨張性組成物1を熱膨張性組成物4に代えた以外は、被覆材1と同様にして被覆材3−2を製造した。以上の方法で得られた被覆材3−1と被覆材3−2を等量で混合することにより、熱膨張性組成物3の液状粒子と、熱膨張性組成物4の液状粒子とが水性媒体に分散してなる被覆材3を得た。
(試験例1)
鋼板(厚み8mm)に対し、乾燥厚みが2mmとなるように各被覆材を塗付け、試験体を作製した。得られた試験体の裏面に熱電対を設置し、試験体の表面側からヒーターにて加熱したときの鋼板裏面温度を測定した。その結果、被覆材1〜3は、いずれも裏面温度が低く抑えられ、良好な耐熱保護性を示した。
50℃で7日間貯蔵後の各被覆材について、上記試験例1と同様の試験を行った。その結果、被覆材1に比べ、被覆材2、被覆材3のほうが裏面温度が低く、良好な耐熱保護性を示した。
