Problems solved by technology

However, there are many problems in actual use. For example, due to the poor water retention of vitrified microbead insulation mortar, cracking and hollowing often occur. Adding chemical water-retaining materials or expansion agents will affect the vitrified microbeads. Other properties of thermal insulation mortar will even directly affect the durability of thermal insulation mortar
Moreover, due to improper operation in construction operations, it will also affect the performance of its thermal insulation performance. People have been studying ways to improve this situation, but in terms of improving its various performances, it is always the same. performance match

Abstract

The invention relates to vitrified microsphere thermal insulation mortar with a self-humidity-control function, which has components as follows: vitrified microsphere, perlite sand, cement, re-dispersible latex powder, high silicon mordenite powder, methyl hydroxyethylcellulose ether, blended fiber, thickener and water reducer. The invention successfully introduces natural zeolite into preparation of the vitrified microsphere thermal insulation mortar, which, on the one hand, improves compactness of the mortar and on the other hand does not reduce thermal insulation performance of the mortar and displays certain hydrophilicity, thus reducing the bleeding of the mortar; when the environmental temperature changes, the mortar is characterized by automatic moisture absorption or release which plays a role of conditioning moisture content of surrounding environment. Therefore, the thermal insulation performance of the mortar is not reduced but the strength is improved. Addition of hydration products in the mortar leads to density of internal structure and improves impermeability and frost resistance of the mortar. At the same time, the zeolite has good acid resistance; and after the natural zeolite is processed into the powder, the dosage of the cement can be replaced which undoubtedly makes contribution to improving the thermal insulation performance.
