Light self-foaming mining filling material, preparation method and application
The invention discloses a light self-foaming mining filling material, a preparation method and application, the light self-foaming mining filling material comprises a component A and a component B, the component A and the component B are liquid components, the component A comprises the following raw materials by weight: 15-20% of alkaline phenolic resin, 8-12% of mica powder, 0.05-0.1% of cellulose ether, 5-9% of expanded perlite, and 5-15% of bicarbonate; 1-2% of cocamidopropyl betaine, and 48-60% of water; and the component B is prepared from the following raw materials in percentage by weight: 30-40% of aluminum sulfate and 60-70% of water. The filling material is foamed at normal temperature, cured at normal temperature, flame-retardant, high-temperature-resistant, high in foaming expansion, good in air tightness, excellent in plugging performance and capable of being conveyed remotely, solves the problems that in the prior art, the foaming performance and the material performance cannot be achieved at the same time, and the filling material is unsafe, and is suitable for filling of mine drill sites and upper corners or plugging of air leakage channels or construction of closed walls.
本发明公开了一种轻质自发泡矿用充填材料、制备方法及应用，包括A组分和B组分，两者均为液体组分，其中，所述A组分由以下重量百分比的原料组成：碱性酚醛树脂15‑20％，云母粉8‑12％，纤维素醚0.05‑0.1％，膨胀珍珠岩5‑9％，碳酸氢盐5‑15％，椰油酰胺丙基甜菜碱1‑2％，水48‑60％；所述B组分由以下重量百分比的原料组成：硫酸铝30‑40％，水60‑70％。该充填材料常温发泡、常温固化，阻燃耐高温，发泡倍数高，气密性好，封堵性能优越，可远距离输送，解决了现有技术发泡性能与材料性能不能兼得、不安全等问题，适用于矿井钻场、上隅角充填，或者封堵漏风通道或构筑密闭墙。
