Mining flexible spraying sealing material, preparation method and application
The invention discloses a mining flexible spraying sealing material, a preparation method and application, the spraying sealing material comprises a component A, a component B and a component C, the component A is a powder material, the component B and the component C are liquid materials, the component A comprises the following raw materials by weight: 60-80% of white cement, 6-17% of silica powder, 8-17% of ground calcium carbonate, 3-10% of a flame retardant, and 0.4-1% of magnesium oxide; the component B comprises the following components in percentage by weight: 3-14% of polyvinyl alcohol, 6-14% of glycerol, 0.05-0.1% of a preservative and 70-88% of water; and the component C comprises the following components in percentage by weight: 0.1-0.3% of borax, 1-14% of calcium formate and 95-97% of water. The spraying sealing material is good in ductility and excellent in flame retardant property, has excellent weathering prevention and seepage prevention functions, has good strain capacity on dynamic deformation of the surface of a roadway and is not prone to cracking after being sprayed, and the problems that mixed guniting is not uniform, a formed solidified body is too large in rigidity, and the solidified body is prone to cracking in an underground humid environment are solved.
本发明公开了一种矿用柔性喷涂密闭材料、制备方法及应用，喷涂密闭材料组成包括A组分、B组分和C组分，A组分为粉料，B、C组分为液料，由以下重量百分比的原料组成：A组分：白水泥60‑80％，硅微粉6‑17％，重质碳酸钙8‑17％，阻燃剂3‑10％，氧化镁0.4‑1％；B组分：聚乙烯醇3‑14％，丙三醇6‑14％，防腐剂0.05‑0.1％，水70‑88％；C组分：硼砂0.1‑0.3％，甲酸钙1‑14％，水95‑97％。该喷涂密闭材料延展性好、阻燃性能优越、具有优良的防风化和防渗功能，对巷道表面动态变形有良好的应变能力，喷涂后不易开裂，解决了混合喷浆不均匀，形成的固结体刚性过大、井下潮湿环境易开裂等问题。
