Plugging light sand and preparation method thereof
The invention discloses a plugging light sand. An inner core is made of construction waste, a layer of shell material wraps the outer portion of the inner core, and the shell material comprises the following raw materials in parts by weight: 10-20 parts of cement, 6-13 parts of silicon-containing sand, 1-3 parts of diatomite, 4-6 parts of sodium fluoride, 2-5 parts of polystyrene-butadiene copolymer, 7-10 parts of potassium bicarbonate, 0.2-0.4 part of lauroyl peroxide and 0.3-0.5 part of trimethylolpropane tris(3-aziridinylpropanoate). The plugging light sand is prepared by preparing construction waste, preparing an outer shell powder material, preparing spherical particles, and carrying out autoclaved curing and the like. The plugging light sand is extremely high in swelling ratio, rapidgelatinization can be achieved, and the plugging effect is improved.
本发明公开了一种封堵轻质砂，内芯为建筑废物，在内芯外包裹一层外壳材料，所述的外壳材料，以重量份为单位，包括以下原料：水泥10‑20份、含硅砂6‑13份、硅藻土1‑3份、氟化钠4‑6份、聚苯乙烯丁二烯共聚物2‑5份、碳酸氢钾7‑10份、过氧化月桂酰0.2‑0.4份、三羟甲基丙烷三(3‑吖丙啶基丙酸酯)0.3‑0.5份，所述的封堵轻质砂是经过制备建筑废物、制备外壳粉体材料、制备球形颗粒，压蒸养护等步骤制成的。本发明封堵轻质砂溶胀比极高，能快速胶凝，提高封堵效果。
