High-strength flame-retardant plugging cementing powder and preparation method thereof
The invention discloses high-strength flame-retardant plugging cementing powder and a preparation method thereof. The high-strength flame-retardant plugging cementing powder comprises the following raw materials in parts by weight: 55-70 parts of a cementing material, 12-24 parts of an expansion material, 3-5 parts of a coagulation accelerator, 1-2 parts of short fibers, 1-2 parts of a hardening accelerator, 2-5 parts of blocked isocyanate, 0.2-0.5 part of p-phenylenediamine and 0.3-0.5 part of trimethylolpropane. The high-strength flame-retardant plugging cementing powder is prepared by the following steps: weighing the raw materials in parts by weight, sequentially adding the raw materials into a mixer at normal temperature and normal pressure, stirring at a constant speed for 30-40 minutes, and packaging and delivering after uniformly stirring. The expansion material formed by combining the coarse aggregate and the fine aggregate is added in the formula, the position needing leaking stoppage can be rapidly filled and compacted through the water expansibility of the expansion material, the rapid water plugging effect is achieved, and in the water plugging process, due to the fact that a solidified body is formed by dense accumulation of the coarse aggregate and the fine aggregate, the water plugging effect is good. The components of the rapid hardening cementing material and the agglutination-promoting and hardening-promoting agent do not change in situ.
本发明公开了一种高强度阻燃封堵胶固粉及其制备方法，包括如下重量份原料：55‑70份胶凝材料，12‑24份膨胀材料，3‑5份促凝剂，1‑2份短纤维，1‑2份促硬剂，2‑5份封闭异氰酸酯，0.2‑0.5份对苯二胺，0.3‑0.5份三羟甲基丙烷；该高强度阻燃封堵胶固粉包括如下步骤制成：按重量份将各组分原料称取后常温常压下依次加入混合机中，匀速搅拌30‑40min，搅拌均匀后包装出库；配方中加入了由粗骨料和细骨料合而成的膨胀材料，通过膨胀材料的遇水膨胀性，能快速将需堵漏处填满、挤实，起到快速堵水的效果，堵水过程中由于固结体为粗细骨料的致密堆积，使快硬胶凝材料、促凝集和促硬剂的成分在原位不发生变化。
