Lightweight thermal insulation composite mortar and production equipment thereof
The invention discloses light-weight thermal-insulation composite mortar and production equipment thereof, and relates to the technical field of composite mortar, and the light-weight thermal-insulation composite mortar comprises 35-40 parts of cement, 8-12 parts of converter slag granules and 12-18 parts of a reinforcing material, the thermal insulation material is prepared from the following raw materials in parts by weight: 16 to 22 parts of composite thermal insulation aggregate, 0.25 to 0.35 part of resin type redispersible latex powder, 0.6 to 0.9 part of cold water type polyvinyl alcohol, 0.1 to 0.2 part of hydroxypropyl methyl cellulose ether, 0.01 to 0.03 part of air entraining agent, 0.06 to 0.1 part of water glass, 0.005 to 0.01 part of inorganic retarder, 8 to 13 parts of polyphenyl granules, 30 to 50 parts of glass beads, 1 to 2 parts of redispersible latex powder and 0.2 to 0.6 part of water-retaining agent. The water-retaining agent is blended, so that the problem that the mortar volume shrinks along with the evaporation of water can be avoided, and in the shrinkage process, if a cement-containing material does not have strength or has very low strength and the shrinkage stress is greater than the tensile force of the material, the shrinkage amount is represented as a relatively concentrated large crack is solved.
本发明公开了轻质保温复合砂浆及其生产设备，涉及复合砂浆技术领域，包括：水泥35‑40份、转炉渣颗粒料8‑12份、补强材料12‑18份，复合隔热骨料16‑22份、树脂型可再分散乳胶粉0.25‑0.35份、冷水型聚乙烯醇0.6‑0.9份、羟丙基甲基纤维素醚0.1‑0.2份、引气剂0.01‑0.03份、水玻璃0.06‑0.1份、无机缓凝剂0.005‑0.01份、聚苯颗粒8‑13份、玻化微珠30‑50份、可再分散乳胶粉1‑2份，保水剂0.2‑0.6份，通过融入保水剂可以避免砂浆体积随着水分的蒸发而收缩，在收缩过程中，含水泥材料若还没有强度或强度很低，收缩应力大于材料的抗张力，收缩量就会表现为比较集中的大裂缝的问题。
