Flexible quick-setting quick-drying fireproof airtight spraying material
The invention discloses a flexible quick-setting quick-drying fireproof closed spraying material which comprises a component E and a component F. The component E is a powder material, the component F is a liquid material, and the component E comprises the following raw materials in percentage by weight: 9-20% of fly ash, 2-6% of calcium oxide, 5-17% of silica powder, 0.1-0.3% of borax, 60-80% of cement clinker, 3-6% of a flame retardant and 0.4-1% of magnesium oxide. The component F is prepared from the following raw materials in percentage by weight: 3 to 14 percent of polyvinyl alcohol, 3 to 14 percent of glycerol, 1 to 14 percent of calcium formate and 70 to 85 percent of water. The material forms a film which takes cement as a framework and has a sealing effect and cohesiveness, is high in adhesion, good in ductility, resistant to weathering and convenient to use and transport, and solves the problems that in the prior art, the rigidity of a consolidated body is too large, mixed guniting is not uniform, the consolidated body is prone to cracking in an underground humid environment, and the transportation amount of guniting is large.
本发明公开了一种柔性速凝快干防火密闭喷涂材料，所述喷涂材料组成包括E、F两组分，E组分为粉料，F组分为液料，其中，E组分组成由以下重量百分比的原料组成：粉煤灰9‑20％，氧化钙2‑6％，硅微粉5‑17％，硼砂0.1‑0.3％，水泥熟料60‑80％，阻燃剂3‑6％，氧化镁0.4‑1％；F组分组成由以下重量百分比的原料组成：聚乙烯醇3‑14％，丙三醇3‑14％，甲酸钙1‑14％，水70‑85％。该材料形成以水泥为骨架的具有封闭作用和粘结性的膜，粘附性强、延展性好、防风化、使用运输方便，解决了现有技术固结体刚性过大、混合喷浆不均匀、井下潮湿环境易开裂、喷浆存在运输量大等问题。
