Outer wall thermal insulation bonding mortar
The invention discloses external wall thermal insulation bonding mortar, which is prepared from the following raw materials in parts by weight: 180 to 270 parts of mixed aggregate, 60 to 90 parts of cementing materials, 25 to 40 parts of additives, 20 to 30 parts of lightweight aggregate, 8 to 12 parts of active mineral materials and 30 to 50 parts of water. According to the external wall thermal insulation bonding mortar, the composition of a gelling substance in the mortar is improved by doping an active mineral material, so that the bonding mortar is compact in structure, and the capability of resisting environmental erosion and damage is enhanced; natural sands with different particle sizes are selected and matched in a one-to-one mode to obtain mixed aggregate, so that the void ratio is reduced, and the compactness, strength and durability of the mortar are enhanced; by doping a moisture-proof agent, an anti-seepage agent and a waterproof agent, the waterproof and moisture-proof performance of the mortar is improved, and the bonding firmness between the mortar and a substrate is guaranteed; and a water reducing agent obtained by mixing triethanolamine, acetic acid, urea, oxalic acid and an amine and formaldehyde condensate in proportion reduces the water-cement ratio, enhances the strength and dry shrinkage performance of mortar and prolongs the durability of the mortar.
本发明公开了一种外墙保温粘接砂浆，包括以下重量份的原料：混合骨料180～270份、胶结料60～90份、外加剂25～40份、轻骨料20～30份、活性矿物料8～12份、水30～50份。该外墙保温粘接砂浆，通过掺入活性矿物材料改善砂浆中胶凝物质的组成，使粘接砂浆结构致密，增强抵抗环境侵蚀破坏的能力；通过选用粒径不同的天然砂一比一互相搭配得到混合骨料以减小空隙率，增强砂浆的密实度，强度和耐久性；通过掺入防潮剂、防渗剂和防水剂改善砂浆的防水和防潮性能，保障砂浆与基底之间黏结的牢固性；通过掺入三乙醇胺、乙酸、尿素、草酸和胺与甲醛缩合物按比例混合得到的减水剂降低水灰比，增强砂浆的强度和干缩性能，延长砂浆耐久性。
