The invention relates to the technical field of cement mortar, in particular to thermal-insulation alkali-resistant wall cement mortar and a preparation method thereof, and the thermal-insulation alkali-resistant wall cement mortar comprises the following components: cement, aggregate, water, strong acid and weak base salt powder and foamed polypropylene particles. According to the invention, by using the dissolvability of the strong acid and weak base salt powder, the strong acid and weak base salt powder is added into the dry material, and then water is added, so that the strong acid and weak base salt powder can be fully dissolved in the water to obtain a weak acid solution, and the weak acid solution is used for stirring the cement, the river sand and the foamed polypropylene particles; the surfaces of the cement, the river sand and the foamed polypropylene particles are weakly acidic, so that the condition of non-uniform properties caused by insufficient mixing of the aggregate is fully solved; by using the foamed polypropylene particles, the cement mortar can have a certain heat insulation effect, and air exists in the foamed polypropylene particles, so that the heat insulation performance of the cement mortar can be improved, and a user can conveniently coat a wall surface for heat insulation.
本发明涉及水泥砂浆技术领域，具体为一种隔热耐碱的墙面水泥砂浆及其制备方法，包括以下成分：水泥、骨料、水、强酸弱碱盐粉末和发泡聚丙烯发泡颗粒。本发明通过使用强酸弱碱盐粉末的可溶解性，在干料中增加强酸弱碱盐粉末，再添加水，可以使强酸弱碱盐粉末充分溶解在水内，从而得到弱酸性溶液，采用弱酸性溶液对水泥、河砂以及发泡聚丙烯发泡颗粒进行搅拌，可以使水泥、河砂以及发泡聚丙烯发泡颗粒得表面呈弱酸性，充分解决了由于骨料混合不充分而导致属性不均匀的情况产生；通过使用发泡聚丙烯发泡颗粒，可以使水泥砂浆具备一定的隔热效果，由于发泡聚丙烯发泡颗粒内部存在空气，可以提升水泥砂浆的隔热性能，便于使用者对墙面进行涂抹隔热。
