Gypsum-based spraying material
The invention provides a gypsum-based spraying material. The gypsum-based spraying material is prepared from the following raw materials in parts by weight: 45 to 55 parts of a gypsum base material, 2 to 5 parts of lightweight aggregate, 40 to 50 parts of fine sand, 0.1 to 0.3 part of a water-retaining agent, 0.3 to 0.5 part of a flame retardant, 0.03 to 0.08 part of a thixotropic agent and 0.1 to 0.3 part of a gypsum retarder. The gypsum-based spraying material disclosed by the invention is prepared by taking a byproduct fluorgypsum obtained by preparing hydrogen fluoride from sulfuric acid and fluorite as a base material and matching with the fine sand, the flame retardant, the water-retaining agent, the thixotropic agent and the lightweight aggregate prepared from the glass beads according to a strict proportion, so that the gypsum-based spraying material is stronger in adhesive force after being sprayed; the gypsum-based spraying material is free of hollowing, cracking and falling phenomena, the construction quality of the gypsum-based spraying material is improved, the fireproof performance of the gypsum-based spraying material is improved after spraying, the fireproof time of the gypsum-based spraying material in use is effectively prolonged, and the fireproof effect of the gypsum-based spraying material is improved. Therefore, the protection performance of the gypsum-based spraying material during use is improved.
本发明提供了一种石膏基喷涂材料，该石膏基喷涂材料由如下重量份的原料制成：石膏基料45‑55份，轻骨料2‑5份，细砂40‑50份，保水剂0.1‑0.3份，阻燃剂0.3‑0.5份，触变剂0.03‑0.08份，石膏缓凝剂0.1‑0.3份。本发明所述的石膏基喷涂材料以用硫酸与氟石制取氟化氢的副产品氟石膏为基料，并配以细砂、阻燃剂、保水剂、触变剂以及玻化微珠制得轻骨料等按照严格配比制得，不仅使得该石膏基喷涂材料在喷涂后附着力更强，不会出现空鼓、裂缝以及脱落的现象，提升石膏基喷涂材料的施工质量，而且使得该石膏基喷涂材料在喷涂后使用时的防火性能得到提升，有效延长了该石膏基喷涂材料在使用时的防火时长，从而提升该石膏基喷涂材料在使用时的防护性能。
