Aerated thermal insulation mortar and preparation method thereof
The invention discloses aerated thermal insulation mortar, which is prepared from the following raw materials: river sand, ordinary Portland cement, polyurethane, an air entraining agent, a foam stabilizer, a water reducing agent, an early strength agent and water. The preparation method comprises the following steps: (1) weighing the raw materials; (2) mixing and stirring river sand and ordinaryPortland cement to obtain a material A; (3) adding a foam stabilizer and an early strength agent, and uniformly stirring to obtain a material B for later use; (4) adding polyurethane into water, and uniformly stirring; (5) adding an air entraining agent, and uniformly stirring to obtain a solution A; (6) adding a water reducing agent, and uniformly stirring to obtain a solution B; and (7) adding the solution B into the material B in two times, and stirring to obtain the product. By adding the air entraining agent and the polyurethane, the dispersity of the polyurethane in the mortar can be greatly improved, the anti-seepage and anti-freezing properties of the mortar are greatly improved, and the thermal insulation mortar which is good in thermal insulation and anti-seepage and anti-freezing properties, non-flammable, not prone to water absorption and simple in construction process is prepared.
本发明公开了一种加气保温隔热砂浆，包括以下原料：河砂、普通硅酸盐水泥、聚氨酯、引气剂、稳泡剂、减水剂、早强剂和水；制备方法：(1)称取各原料；(2)将河砂和普通硅酸盐水泥混合搅拌，得到物料A；(3)加入稳泡剂和早强剂，搅拌均匀，得到物料B，备用；(4)将聚氨酯加入水中，搅拌均匀；(5)加入引气剂，搅拌均匀，得到溶液A；(6)加入减水剂，搅拌均匀，得到溶液B；(7)将溶液B分为两次加入到物料B中，搅拌，即得。本发明通过加入引气剂和聚氨酯，能够大大改善聚氨酯在砂浆中的分散性，并且极大提高砂浆的抗渗抗冻性能，配制出一种保温隔热、抗渗抗冻性良好、不易燃、不易吸水、施工工艺简单的保温砂浆。
