Compression-resistant hollowing-free thermal insulation mortar
The invention discloses compression-resistant hollowing-free thermal insulation mortar which comprises the following raw materials in parts by weight: 40-50 parts of Portland cement, 10-15 parts of fly ash, 10-20 parts of vitrified micro bubbles, 5-10 parts of expanded perlite, 5-10 parts of diatomite, 5-10 parts of silicon dioxide aerogel, 3-7 parts of redispersible latex powder, 1-2 parts of starch ether, 1-2 parts of cellulose ether, 3-5 parts of porous fibers and 1-2 parts of an air entraining agent. The fly ash and the air entraining agent are doped into the thermal insulation mortar, sothat the dry density and the heat conductivity coefficient of the thermal insulation mortar can be obviously reduced, and the performance of the thermal insulation mortar meets the technical requirements. The expanded perlite is added, so that the bonding strength with the wall body is improved to prevent hollowing and falling. The porous fibers are doped into the thermal insulation mortar, so that the compressive strength of the mortar is effectively improved. Through selection and content adjustment of the raw materials, the prepared compression-resistant hollowing-free thermal insulation mortar is good in thermal insulation effect, high in mechanical strength and free of hollowing, cracking and other problems.
本发明公开了一种抗压无空鼓的保温隔热砂浆，包括以下按重量份数计的原料：硅酸盐水泥40‑50份、粉煤灰10‑15份、玻化微珠10‑20份、膨胀珍珠岩5‑10份、硅藻土5‑10份、二氧化硅气凝胶5‑10份、可再分散乳胶粉3‑7份、淀粉醚1‑2份、纤维素醚1‑2份、多孔纤维3‑5份、引气剂1‑2份。本发明在保温砂浆中掺加粉煤灰和引气剂，可明显降低保温砂浆的干密度和导热系数，使保温砂浆性能达到技术要求。加入膨胀珍珠岩，增加与墙体的粘合强度以防止空鼓、脱落。在保温砂浆中掺入多孔纤维，有效提高砂浆的抗压强度。本发明通过原材料的选择和含量调整，制备的抗压无空鼓的保温隔热砂浆保温隔热效果好，且力学强度高，无空鼓开裂等问题。
