Cement-based phase-change waterproof plugging material

The invention discloses a cement-based phase-change waterproof plugging material, and belongs to the field of plugging material. The cement-based phase-change waterproof plugging material is prepared from, by mass, 30 to 60 parts of Portland cement, 30 to 60 parts of sulfur aluminum cement, 2 to 5 parts of calcium powder, 0.2 to 3 parts of silica fume, 0.1 to 0.5 part of a quick drying agent, 0.5 to 2 parts of a phase-change special adhesive powder, 0.01 to 0.06 part of starch ether, 0.01 to 0.3 part of a water reducing agent, and 0.1 to 0.6 part of permeable crystallization master batch. The phase-change special adhesive powder is added, so that the difference of setting time of the cement-based phase-change waterproof plugging material at different environment temperatures is small, setting time is stabilized, product performance stability is increased, and construction is more convenient and rapid. 本发明公开了种水泥基相变防水堵漏材料，属于堵漏材料领域。它由以下质量份数的组分配制而成：硅酸盐水泥30～60份，硫铝水泥30～60份，钙粉2～5份，硅灰0.2～3份，快干剂0.1～0.5份，相变特种胶粉0.5～2份，淀
