High-efficiency permeable water-resistant sand solidification agent and preparation method thereof
The invention discloses a high-efficiency permeable water-resistant sand-fixing agent and a preparation method thereof, and relates to the technical field of concrete building materials, the high-efficiency permeable water-resistant sand-fixing agent comprises the following raw materials: organic and inorganic silicate, modified styrene-acrylic emulsion, a dispersing aid, a penetrant, a defoaming agent, a bactericide and water; wherein the modified styrene-acrylic emulsion is prepared from styrene, ethyl methacrylate, methyl acrylate, maleic acid, acrylic acid and trifluoroethyl methacrylate; the dispersing aid is 2-amino-2-methyl-1-propanol and gamma-aminopropyltriethoxysilane, and the mass ratio of the 2-amino-2-methyl-1-propanol to the gamma-aminopropyltriethoxysilane is 1: 1. By compounding the styrene-acrylic emulsion and the dispersing aid, the permeability, the water resistance and the adhesive force of the sand solidification agent are further improved, the dusting and dusting effects of the concrete surface are improved, and in the actual application process, the wall surface pretreatment can be simplified, and manpower, material resources and financial resources can be saved.
本发明公开了一种高效渗透型耐水固沙剂及其制备方法，涉及混凝土建筑材料技术领域，所述高效渗透型耐水固沙剂包括以下原料：有机无机硅酸盐，改性苯丙乳液，分散助剂，渗透剂，消泡剂，杀菌剂，水；其中改性苯丙乳剂由苯乙烯、甲基丙烯酸乙酯、丙烯酸甲酯、马来酸、丙烯酸、甲基丙烯酸三氟乙酯制备得到；分散助剂为2‑氨基‑2‑甲基‑1‑丙醇、γ‑氨丙基三乙氧基硅烷，两者质量比为1:1。本发明通过复配苯丙乳液和分散助剂，进一步提高了固沙剂的渗透性、耐水性和附着力，改善了混凝土表面起沙、起尘效果，在实际应用过程中，还能简化墙面预处理，节省人力物力财力。
