Description
本開示が解決しようとする課題は、不燃性と高接着性能とを有する板材積層物を製造可能な板材コーティング剤及び板材の提供である。
<実施例1>
ホウ酸(炭化促進成分)と、リン酸二水素アンモニウム(連鎖抑制成分)と、珪砂(粒径5μm~95μmの混合粉末であるバインダ粒子。非真球状で、焼結していない二酸化ケイ素)とを、質量比で1:6:2の割合で秤量し、溶媒として水を用いて、35質量%のスラリー状の分散液(板材加工用組成物)を作製した。
表面コーティング層14を形成しなかったこと以外は実施例1と同様にして板材積層物10を作製し、不燃試験、浸漬剥離試験、及び煮沸剥離試験を行った。この結果、作製した板材積層物10は不燃性を有していた。また、浸漬剥離試験及び煮沸剥離試験のいずれにおいても剥離は認められず、実施例1と同様に、第1板材11及び第2板材12は、高い接着能力を有することが確認できた。
珪砂(バインダ粒子)を使用しないこと以外は実施例1と同様にして板材積層物10を作製し、不燃試験、浸漬剥離試験、及び煮沸剥離試験を行った。この結果、作製した板材積層物10は不燃性を有していた。しかし、浸漬剥離試験及び煮沸剥離試験のいずれにおいても、10mmを超える大きな剥離が認められた。従って、第1板材11及び第2板材12の接着能力は低いことが分かった。この理由は、炭化促進成分及び連鎖抑制成分が吸湿した結果、内部の水分に起因して剥離が生じたと考えられる。また、これらは弱い接着力で接着しているため、これらの間に隙間が生じ易い。このため、水分が隙間に侵入し易いため、更に、侵入した水分に起因して剥離が生じたと考えられる。
<実施例3>
図5は、実施例3で使用した板材1の上面図である。図6は、図5のA-A線断面図である。棒部材1022(図4)を用いた穿孔工程S2(図3)により、図5及び図6に示す示す板材1を作製した。孔20は等間隔で形成され、いずれも同じ形状を有する。板材1の厚さL1は20mmで、孔20は、上面視で円形であり、板材1の両面に複数個形成した。孔20の大きさ(直径)L2は、0.5mm~1mm、隣接する孔20の間隔L3は10mm、孔20の深さL4は3mmとした。1つの孔20の深さは、板材1の厚さに対して15%であるが、孔20は、2つの表面110にそれぞれ形成されるため、合計で、板材1の厚さに対して30%である。そして、作製した板材1の質量を測定した。
孔20を備えないこと以外は実施例3と同様にして、板材加工用組成物の質量を決定した。
実施例3及び実施例4の結果を下記の表1に示す。
<実施例5>
実施例1の板材加工用組成物に対し更にセラミック粒子を添加し、実施例5の板材加工用組成物を作製した。セラミック粒子は、真球状で大きさ直径8μm(レーザー回折式散乱法に基づく平均粒径)のシリカ(二酸化ケイ素の焼結体)を使用し、使用量は、板材加工用組成物に対して1質量%とした。
