The invention discloses a passive house thermal insulation wallboard, which is prepared from the following raw materials in parts by weight: 50-70 parts of construction waste; 5-10 parts of furnace slag; 1-3 parts of talcum powder; 5-10 parts of glass cellulose; 3-5 parts of a foaming agent; 15-20 parts of river sand; 1-3 parts of hydroxyethyl cellulose; and 0.3-0.5 part of calcium lignosulphonate. The preparation method comprises the following steps: (1) weighing the raw materials; (2) putting the construction waste, the furnace slag, the talcum powder and the glass cellulose into a ball mill, and carrying out fine grinding; (3) adding the hydroxyethyl cellulose, the foaming agent and water, stirring in stirring equipment, and foaming; and (4) mixing the foaming slurry with the river sandand the calcium lignosulphonate, performing uniform stirring to obtain a mixture, putting the mixture into a mold, preparing a billet, and performing steam curing on the billet to obtain the finishedproduct thermal insulation wallboard. The product provided by the invention has the advantages of light weight, heat insulation, good flame retardant property and excellent water resistance, and particularly meets the application requirements of passive house buildings and indoor sound insulation, heat insulation, heat preservation and the like of civil buildings; and the manufacturing process issimple, low in cost and suitable for large-area production and popularization.
本发明公开了一种被动房保温墙板，由以下重量份的原料制成：建筑垃圾50～70份；炉渣5～10份；滑石粉1～3份；玻璃纤维素5～10份；发泡剂3～5份；河沙15～20份；羟乙基纤维素1～3份；木钙0.3～0.5份。制备方法为：(1)称取各原料；(2)将建筑垃圾、炉渣、滑石粉和玻璃纤维素放入球磨机中细磨；(3)加入羟乙基纤维素、发泡剂和水，并在搅拌设备中搅拌；发泡；(4)将发泡浆料与河砂、木钙混合并搅拌均匀得到混合料，将上述混合料放入模具中制坯，生坯经过蒸汽养护得保温墙板成品。本发明的产品具有轻质、隔热、阻燃性能好和耐水性能优良的优点，特别符合“被动房”建筑使用及民用建筑的室内隔音、绝热、保温等应用；同时制作工艺简单，成本低，适合大面积生产推广。
