Lightweight high-strength cement-based foam thermal insulation material and preparation method thereof
The invention discloses a lightweight high-strength cement-based foam thermal insulation material and a preparation method thereof. The lightweight high-strength cement-based foam thermal insulation material is prepared from the following materials in parts by weight: 35-65 parts of water, 0-75 parts of ordinary Portland cement, 5-70 parts of superfine Portland cement, 0-10 parts of sulphoaluminate cement, 5-25 parts of superfine active admixture, 6-10 parts of foaming agent, 0.5-3.5 parts of assistant and 0.5-2 parts of polypropylene fiber. The preparation method comprises the following steps: firstly adding 35-65 parts of water, 0.5-3.5 parts of assistant and 0.5-2 parts of polypropylene fiber into a stirring device, and stirring for 15-40 seconds to obtain an initial solution; then adding 0-75 parts of ordinary Portland cement, 5-70 parts of superfine Portland cement, 0-10 parts of sulphoaluminate cement and 5-25 parts of superfine active admixture into the initial solution, stirring for 10-20 seconds, adding a foaming agent, stirring to obtain slurry, finally pouring the slurry into a mold, standing for foaming, and maintaining at constant temperature and humidity. The lightweight high-strength cement-based foam thermal insulation material obtained in the invention has the advantages of high strength, low water absorption, good thermal insulation performance and low density.
本发明公开了一种轻质高强水泥基泡沫保温材料及其制备方法，轻质高强水泥基泡沫保温材料包括如下重量比的材料制成：水35~65份、普通硅酸盐水泥0~75份、超细硅酸盐水泥5~70份、硫铝酸盐水泥0~10份、超细活性掺合料5~25份、发泡剂6~10份、助剂0.5~3.5份、聚丙烯纤维0.5~2份。制备时，先将水35~65份、助剂0.5~3.5份、聚丙烯纤维0.5~2份加入到搅拌装置搅拌15~40s，得到初始溶液；再将普通硅酸盐水泥0~75份、超细硅酸盐水泥5~70份、硫铝酸盐水泥0~10份、超细活性掺合料5~25份加入到初始溶液中搅拌10~20s，然后加入发泡剂搅拌后制得浆料，最后将浆料倒入模具内静停发泡、恒温恒湿养护。本发明得到的轻质高强水泥基泡沫保温材料强度高、吸水率低、保温性能好且密度小。
