Preparation method of composite ternary system sludge curing agent
The invention relates to the technical field of sludge curing agents, and discloses a preparation method of a composite ternary system sludge curing agent, which comprises the following steps: stirring a ternary cementing material, mineral powder and reduced slag in a stirrer to form a material A; mixing a polyacrylate emulsion, a styrene-acrylic emulsion and a water body, and stirring to form a material B; the material A and the material B are placed in a stirrer to be stirred, and the composite ternary system sludge curing agent is formed. The ternary cementing materials are Portland cement, sulphoaluminate cement and gypsum, ternary system solidification can be generated, a set cement structure is reinforced and densified, it is guaranteed that the later strength of the cement is increased, mineral powder slag reduction solidification is generated through mineral powder and alkaline residues, the whole solidification system is reinforced, and the later strength development of the whole solidification system is good; the performance of a soil body is improved by doping polyacrylate emulsion and styrene-acrylic emulsion high polymer materials, so that the cured sludge has the characteristics of extremely fast early strength development, good water stability and high later strength.
本发明涉及淤泥固化剂的技术领域，公开了复合三元体系淤泥固化剂制备方法，包括将三元胶凝材料、矿粉以及减渣置于搅拌机中进行搅拌，形成A材料；将聚丙烯酸酯乳液、苯丙乳液以及水体混合进行搅拌，形成B材料；将A材料以及B材料分别置于搅拌机中搅拌，形成复合三元体系淤泥固化剂。三元胶凝材料分别为硅酸盐水泥、硫铝酸盐水泥及石膏，其会发生三元体系固化，加固并致密了水泥石结构，保证水泥后期强度的增长，通过矿粉、碱渣发生矿粉减渣固化，强化了整个固化体系且使其后期强度发育良好；通过掺入聚丙烯酸酯乳液及苯丙乳液高分子材料来改善土体性能，使固化的淤泥具有前期强度发育极快、水稳性好、后期强度高的特点。
