Permeable sand-fixing waterproof agent and preparation method thereof
The invention relates to a permeable sand-fixing waterproof agent and a preparation method thereof. The permeable sand-fixing waterproof agent is prepared from the following raw materials in parts byweight: 430-460 parts of styrene-acrylic emulsion, 90-110 parts of water glass, 2-4 parts of a dispersing agent, 0.8-1.2 parts of a defoaming agent and 440-460 parts of water. The preparation method comprises the following steps: dividing water into two parts to obtain a first water component and a second water component; sequentially adding a dispersing agent and a defoaming agent into the firstwater component, and stirring to obtain a mixture a after the system is uniform; adding styrene-acrylic emulsion into the mixture a, and uniformly stirring to obtain a mixture b; and adding water glass and the second water component into the mixture b, uniformly stirring, and discharging to obtain the permeable sand-fixing waterproof agent. After the permeable sand-fixing waterproof agent is dopedinto concrete, the waterproof and anti-seepage pressure performance and the secondary anti-seepage pressure performance of the concrete reach optimal values. The preparation method only needs to uniformly stir and mix the raw materials, the process is simple and easy to control, and large-scale production is facilitated.
本发明涉及一种渗透固沙防水剂及其制备方法。所述渗透固沙防水剂，包括如下重量份的原料：苯丙乳液430～460份、水玻璃90～110份、分散剂2～4份、消泡剂0.8～1.2份和水440～460份。所述制备方法为：将水分成两份，得第一水组分和第二水组分；向第一水组分中依次加入分散剂、消泡剂进行搅拌，体系均匀后得混合物a；向混合物a中加入苯丙乳液，搅拌均匀后得混合物b；向混合物b中加入水玻璃和第二水组分，搅拌均匀后出料即得渗透固沙防水剂。所述渗透固沙防水剂掺入混凝土后，混凝土的防水抗渗压力及第二次抗渗压力性能均达到较优值；所述制备方法仅需将原料均匀搅拌混合即可，工艺简单易控，有利于规模化产出。
