Wall thermal insulation slurry and preparation method thereof
The invention relates to wall thermal insulation slurry. The slurry is prepared from the following raw materials in percentage by weight: 15 to 25 percent of aerogel compound, 22 to 28 percent of glass beads, 5 to 10 percent of polymer emulsion, 12 to 20 percent of heavy calcium powder, 3 to 6 percent of barium sulfate, 2 to 4 percent of modifier, 1 to 2 percent of flame retardant, 0.3 to 0.5 percent of wetting agent and the balance of water; the aerogel compound is added in the formula, meanwhile, the preparation process of the aerogel is optimized, the dry density of the slurry can be reduced, the phase-change material and the modifier polystyrene microspheres are added in the preparation process at the same time, and the phase-change material and the polystyrene microspheres both have the effect of improving the heat insulation performance of the slurry, and can be doped into a fragile network system of the aerogel, so as to improve the structural continuity of the aerogel; compared with gaps in the aerogel, the phase-change material and the polystyrene microspheres filling the aerogel can synergistically maintain high heat insulation and heat storage capacity; and the polystyrene microspheres are added, so that the strength of the aerogel can be improved to a certain extent.
一种墙体隔热保温浆料，由以下重量百分比的原料组成：气凝胶复合物15‑25％、玻化微珠22‑28％、聚合物乳液5‑10％、重钙粉12‑20％、硫酸钡3‑6％、改性剂2‑4％、阻燃剂1‑2％、润湿剂0.3‑0.5％，余量为水；配方中添加气凝胶复合物，同时优化气凝胶的制备过程，不仅可以降低浆料的干密度，而且在制备中同时添加相变材料和改性剂聚苯乙烯微球，相变材料和聚苯乙烯微球均具有提高在提高浆料的绝热性能的同时，可以掺入气凝胶较为脆弱的网络体系中，改善其结构连续性，相对于气凝胶中的空隙，填充在其中的相变材料和聚苯乙烯微球可以协同保持较高的隔热和储热能力；添加聚苯乙烯微球，还能在一定程度上改善气凝胶的强度。
