Building thermal insulation mortar formula and test method
The invention discloses a building thermal insulation mortar formula and a test method, the building thermal insulation mortar formula comprises 425 cement, fly ash, glass beads, hydroxypropyl methyl cellulose, rubber powder and PP fiber, and the hydroxypropyl methyl cellulose is composed of 90% of a hydroxypropyl methyl cellulose pure product, 3% of industrial sugar, 3% of starch ether, 2% of talcum powder, 1% of fiber and 1% of polyacrylamide. Compared with the prior art, the modified hydroxypropyl methyl cellulose has the advantages that the compressive strength of the thermal insulation mortar prepared from the modified hydroxypropyl methyl cellulose is obviously improved, the dry density and the heat conductivity coefficient are obviously reduced, and the dry density, the heat conductivity coefficient and the compressive strength are obviously superior to those of the thermal insulation mortar prepared from the modified hydroxypropyl methyl cellulose by adding the organic polymer and the air entraining agent into the hydroxypropyl methyl cellulose; the dry density, the heat conductivity coefficient and the compressive strength of the thermal insulation mortar are remarkably improved, and the performance is better than that of commercially available like products.
本发明公开了一种建筑保温砂浆配方及测试方法，包括：425水泥、粉煤灰、玻化微珠、羟丙基甲基纤维素、胶粉、PP纤维，羟丙基甲基纤维素由羟丙基甲基纤维素纯产品90％、工业糖3％、淀粉醚3％、滑石粉2％、纤维1％、聚丙烯酰胺1％组成，本发明具有以下优点：本发明的改性羟丙基甲基纤维素制备的保温砂浆抗压强度明显提高，干密度、导热系数明显降低，且干密度、导热系数和抗压强度显著优于本发明在羟丙基甲基纤维素中加入有机高分子和引气剂，显著提高了保温砂浆的干密度、导热系数和抗压强度，比市售的同类产品性能要好。
