Glass wool for building and partition plate containing glass wool
The invention provides glass wool for buildings and a partition plate containing the glass wool. The glass wool is prepared through the following steps: step S1, dipping a glass wool raw material with acid, and then conducting cleaning to obtain acid-leached glass wool; S2, dispersing nano-TiO2 in a solvent so as to obtain a nano-TiO2 dispersion liquid; S3, dipping the acid-leached glass wool in the nano-TiO2 dispersion liquid, and conducting drying to obtain pretreated glass wool; and S4, impregnating the pretreated glass wool with a silane coupling agent solvent, and conducting drying to obtain the modified glass wool. Compared with the prior art, the invention has the beneficial effects that the glass wool is subjected to acid corrosion to increase the hydrophilicity of the glass wool; then the glass wool is soaked in the titanium dioxide dispersion liquid, so the loading capacity of titanium dioxide is increased, and the ageing resistance of the superfine glass wool is improved; and after the nano-TiO2 is deposited, the silane coupling agent is finally used for sealing layer modification, so moisture resistance is prevented from being reduced after the glass wool is corroded in an early stage.
本发明提供一种建筑用玻璃棉及包含该玻璃棉的隔板，包括：步骤S1：将玻璃棉原料先采用酸浸渍，然后进行清洗，得到酸浸玻璃棉；步骤S2：将纳米TiO2分散在溶剂中，得到纳米TiO2分散液；步骤S3：将酸浸玻璃棉浸渍在所述纳米TiO2分散液中干燥后，得到预处理玻璃棉；步骤S4：将所述预处理玻璃棉采用硅烷偶联剂溶剂浸渍，干燥后得到修饰玻璃棉。与现有技术相比，本发明的有益效果在于：本发明先将玻璃棉酸腐蚀增加其亲水性，然后利用浸渍在二氧化钛分散液中，有利于加大二氧化钛的负载量，提高了超细玻璃棉的抗老性；在纳米TiO2沉积后，最后利用硅烷偶联剂进行封层修饰，避免因前期腐蚀玻璃后，造成耐潮性下降。
