The invention discloses a method for preparing polymer cement waterproof mortar from quartz sand, and relates to the technical field of building materials. Comprising the following steps: step 1, material preparation: preparing Portland cement, quartz sand, a water reducing agent, a water repellent, a water-retaining agent, a modified acrylic emulsion, a 4-acetoxystyrene-acrylate copolymer emulsion, trimethylsilyl polyphosphoric acid and water which serve as raw materials; step 2, material mixing: mixing and stirring Portland cement, quartz sand, a water reducing agent, a water repellent and a water-retaining agent according to a ratio to obtain a powder material, and mixing and stirring a modified acrylic emulsion, a 4-acetoxystyrene-acrylate copolymer emulsion, trimethylsilyl polyphosphoric acid and water according to a ratio to obtain a liquid material; and step 3, equally dividing the liquid material into a plurality of parts of separated liquid materials according to the weight, and pouring the plurality of parts of separated liquid materials into the powder material for stirring. According to the present invention, the compressive strength and the breaking strength are significantly improved while the water absorption rate is reduced.
本申请公开了一种利用石英砂制备聚合物水泥防水砂浆的方法，涉及建筑材料技术领域，包括如下步骤：步骤1、材料整备：将作为原材料的硅酸盐水泥、石英砂、减水剂、憎水剂、保水剂、改性丙烯酸乳液、4‑乙酰氧基苯乙烯‑丙烯酸酯共聚乳液、三甲基甲硅烷基聚磷酸和水；步骤2、材料混合：将硅酸盐水泥、石英砂、减水剂、憎水剂、保水剂按照配比混合搅拌并获得粉料，将改性丙烯酸乳液、4‑乙酰氧基苯乙烯‑丙烯酸酯共聚乳液、三甲基甲硅烷基聚磷酸和水按照配比混合搅拌并获得液料；步骤3、将液料按重量等分为多份分液料，再将多份分液料倒入粉料内搅拌。本申请具有在显著提升抗压强度和抗折强度的同时降低吸水率的效果。
