Anti-corrosion anti-erosion high-strength mortar and preparation method thereof
The invention relates to anti-corrosion anti-erosion high-strength mortar and a preparation method thereof.The mortar is prepared from, by weight, 80-120 parts of cement, 20-30 parts of quartz sand, 10-25 parts of modified bentonite, 10-20 parts of composite fibers, 6-12 parts of preservative, 5-10 parts of acrylic emulsion, 5-10 parts of water reducing agent, 3-6 parts of coupling agent and 30-60 parts of water; the modified bentonite is prepared by modifying bentonite with a 1-10 wt% dilute acid solution and a 10-20 wt% aluminum sulfate solution; the preservative is obtained by mixing 5-10 parts of a mixture A, 10-20 parts of PTB emulsion and 5-10 parts of deionized water, and the mixture A is prepared by mixing 5-10 parts of monopotassium phosphate, 5-10 parts of dead burned magnesia powder, 3-6 parts of aluminum zinc tripolyphosphate and 2-4 parts of borax. The preservative prepared by the invention is inserted into a modified bentonite sheet layer, and is more tightly combined with Portland cement under the action of the acrylic emulsion and the coupling agent, so that the corrosion resistance of the modified bentonite is enhanced, particularly the erosion of acidic water is prevented, and the weather resistance is strong.
本发明涉及一种防腐抗冲蚀高强砂浆及其制备方法，其中，砂浆包括按重量份计的：水泥80‑120份、石英砂20‑30份、改性膨润土10‑25份、复合纤维10‑20份、防腐剂6‑12份、丙烯酸乳液5‑10份、减水剂5‑10份、偶联剂3‑6份、水30‑60份；所述改性膨润土由1‑10wt％稀酸溶液和10‑20wt％硫酸铝溶液对膨润土改性之后制得；所述防腐剂由5‑10份混合料A、10‑20份PTB乳液以及5‑10份去离子水混合得到，其中，所述混合料A由5‑10份磷酸二氢钾、5‑10份重烧氧化镁粉、3‑6份三聚磷酸铝锌以及2‑4份硼砂混合制得。本发明所制备的防腐剂穿插在改性膨润土片层中，在丙烯酸乳液和偶联剂作用下，与硅酸盐水泥结合更加紧密，增强其防腐性特别是防止酸性水的冲蚀，且耐候性强。
