<試験例>
ホルムアルデヒド濃度低減性能については、JIS A 1901「建築材料の揮発性有機化合物(VOC)、ホルムアルデヒド及び他のカルボニル化合物放散測定法法−小形チャンバー法」に準拠した容積20リットルの小形チャンバーに評価用サンプルを設置して測定を行った。ただし、サンプル表面に光が照射されるようにチャンバーには強化ガラスによる透明部を設け、サンプル表面にて照度1000lx、紫外線強度1.0μW/cm2となるよう蛍光灯を用いて光を連続照射した。紫外線強度は、TOPCON社製紫外線強度計UVR−2に同社製受光部UD−36を装着した状態で測定した値である。チャンバーには一定濃度のホルムアルデヒドを含む空気供給した状態で、温度28℃、相対湿度50%、換気回数0.5回/h、試料負荷率1.1m2/m3の条件において24時間連続運転した後、チャンバー給気および排気の空気を捕集してホルムアルデヒド濃度の測定を行った。
Qe=n/L・(Cout−Cin)/Cout
で表される。ただし、nは換気回数、Lは試料負荷率である。
(2)調湿性能
調湿性能については、JIS A 1470-1「調湿建材の吸放湿性試験方法−第1部:湿度応答法−湿度変動による吸放湿試験方法」に準拠し、中湿域における試験により測定を行った。得られた吸湿量および放湿量の結果によって評価を行った。
(3)耐光性能
耐光性能については、JIS K 5600-7-5「塗料一般試験方法−第7部:塗膜の長期耐久性−第5節:耐光性」に準拠し、キセノンランプにて500hr照射を行い、初期との変色を色差計にて測定した。
(4)透湿性能
透湿性能については、JIS A 1324「建築材料の透湿性測定法法」に示される透湿試験箱法に準拠して測定を行い、透湿抵抗を結果から算出した。比較例5〜7は、無機保護層の透湿抵抗を測定するために、吸湿性を有する珪藻土を基材から取り除いた評価用サンプルである。比較例5の透湿抵抗値から比較例7の透湿抵抗値を差し引くことにより、酸化ケイ素ゾルを配合した無機保護層の透湿抵抗を算出することができる。同様に、比較例6の透湿抵抗値から比較例7の透湿抵抗値を差し引くことにより、酸化ケイ素ゾルを配合しない無機保護層の透湿抵抗を算出することができる。
(5)結果
これらの性能評価結果について、表1に示した。実施例1および2はいずれも比較例に比べて、大きなホルムアルデヒド濃度低減性能、調湿性能および耐光性能を示した。
