Lightweight thermal-insulation water-resistant magnesium oxysulfate board and preparation method thereof
The invention discloses a lightweight thermal-insulation water-resistant magnesium oxysulfate board which is prepared by coating slurry and then lagging foaming, and the slurry comprises the following components in parts by mass: 100 parts of magnesium oxide, 100-150 parts of a magnesium sulfate aqueous solution, 5-10 parts of magnesium whiskers, 15-35 parts of lightweight filler, 1-3 parts of a waterproof agent, 2-5 parts of fibers, 4-8 parts of a curing modifier and 2-8 parts of a protein foaming agent; the light filler comprises aerogel powder and/or rice husks; the waterproof agent is sodium silicate and/or potassium silicate; the curing modifier comprises organic acid and ferrous sulfate. The lightweight thermal-insulation water-resistant magnesium oxysulfate board not only has good fire resistance, pressure resistance and wear resistance, but also is light in weight and excellent in water resistance, and the obtained magnesium oxysulfate board is widely applied to the fields of lightweight wallboards, fire-resistant components, thermal-insulation boards and ventilation pipelines of the lightweight wallboards, the fire-resistant components, the thermal-insulation boards and the ventilation pipelines of the thermal-insulation boards.
本发明公开了一种轻质保温耐水硫氧镁板，由浆料涂覆后滞后发泡制得，按质量份数计，浆料包括氧化镁100份、硫酸镁水溶液100～150份、镁质晶须5～10份、轻质填料15～35份、防水剂1～3份、纤维2～5份、固化改性剂4～8份、蛋白发泡剂2～8份；轻质填料包括气凝胶粉末和/或稻壳；防水剂为硅酸钠和/或硅酸钾；固化改性剂包括有机酸和硫酸亚铁。该轻质保温耐水硫氧镁板不仅具有良好的耐火性、抗压性和耐磨性，且质量轻、耐水性优异，所得硫氧镁板广泛地应用于轻质墙板、耐火构件、保温隔热板及其通风管道领域。
