Seawater-resistant bentonite engineering slurry and preparation method thereof
The invention discloses seawater-resistant bentonite engineering slurry, and belongs to the field of preparation of engineering slurry, and the seawater-resistant bentonite engineering slurry is prepared from the following components in parts by mass: 80-100 parts of calcium bentonite; 2-3 parts of sodium carbonate; 2-4 parts of sodium silicate; 2 to 4 parts of sodium chromate; 2-4 parts of sodium borate; 4 to 8 parts of sodium polyphosphate; 1-3 parts of magnesium oxide; 1 to 3 parts of titanium dioxide; 0.5 to 1 part of a flocculating agent; 0.8 to 1.5 parts of a stabilizing agent; and 16 to 20 parts of water. The preparation method comprises the following steps: performing sodium modification on calcium bentonite and sodium carbonate to form sodium bentonite; and then sodium silicate, sodium chromate, sodium borate and sodium polyphosphate are added and mixed, so that the bentonite engineering slurry disclosed by the invention has better corrosion resistance, can resist seawater to the greatest extent, and meets the requirements of ocean engineering.
本发明公开了一种耐海水膨润土工程泥浆，属于工程泥浆的制备领域，按照质量份计，所述的耐海水膨润土工程泥浆由以下组分制备：钙基膨润土：80～100份；碳酸钠：2～3份；硅酸钠：2～4份；铬酸钠：2～4份；硼酸钠：2～4份；多聚磷酸钠：4～8份；氧化镁：1～3份；二氧化钛：1～3份；絮凝剂：0.5～1份；稳定剂：0.8～1.5份；水：16～20份。本发明中首先通过钙基膨润土、碳酸钠进行钠化，形成钠基膨润土；之后在其中添加硅酸钠、铬酸钠、硼酸钠、多聚磷酸钠的混合，使得本发明的膨润土工程泥浆更佳的防腐性能，因而能最大程度的耐海水，满足海洋工程的需求。
