High-strength water-resistant rock wool phosphogypsum wallboard and preparation method thereof
The invention provides a high-strength water-resistant rock wool ardealite wallboard and a preparation method thereof, the wallboard comprises an ardealite board and rock wool, the ardealite board is prepared from the following raw materials in parts by weight: 30-60 parts of ardealite, 20-30 parts of quick lime, 5-10 parts of modified solid epoxy resin and 0.01-0.1 part of a retarder, and the addition amount of water is 1.5 times of the total amount of the quick lime and the ardealite; the modified solid epoxy resin is powder prepared by blending and extruding 100 parts of a solid epoxy resin E20 or MPES-904 raw material, 20-30 parts of an anhydride curing agent, 1-3 parts of an imidazole curing agent and 3-5 parts of an amphoteric active agent; the anhydride curing agent is phthalic anhydride or tetrahydrophthalic anhydride, the imidazole curing agent is dimethylimidazole, and the amphoteric active agent is sodium dodecyl benzene sulfonate; and the retarder is citric acid, sodium tripolyphosphate or sodium hexametaphosphate. According to the method, the powder raw materials are good in dispersity, so that the prepared wallboard is high in strength and good in water resistance.
本发明提供一种高强耐水岩棉磷石膏墙板及其制备方法，墙板包括磷石膏板和岩棉，磷石膏板由以下重量份数的原料制成：磷石膏30‑60份、生石灰20‑30份、改性固体环氧树脂5‑10份、缓凝剂0.01‑0.1份，水的添加量为生石灰和磷石膏总量的1.5倍；改性固体环氧树脂是由固体环氧树脂E20或MPES‑904原料100份、酸酐固化剂20‑30份、咪唑类固化剂1‑3份、两性活性剂3‑5份共混挤出后制得的粉体；酸酐类固化剂为邻苯二甲酸酐或四氢邻苯二甲酸酐，咪唑类固化剂为二甲基咪唑，两性活性剂为十二烷基苯磺酸钠；缓凝剂为柠檬酸、三聚磷酸钠或六偏磷酸钠。本申请的方法因粉末原料分散性好，制得的墙板高强、耐水性好。
