Problems solved by technology

The above materials play an indispensable role in improving the water retention and thixotropy of thermal insulation mortar, but cellulose derivatives are easily degraded by microbial erosion, which will cause the finished thermal insulation mortar to lose its water retention effect and thixotropy due to cellulose degradation. Reduced denaturation resulting in difficulty in construction

Abstract

The invention discloses an efficient thermal-insulation mortar. No effective measures are provided for the situation that the water-retaining property and the thixotropy of the thermal-insulation mortar used at present are poor due to micro-biological degradation. According to the efficient thermal-insulation mortar disclosed by the invention, polyethylene glycol is added into the traditional thermal-insulation mortar, so that the water-retaining property and the thixotropy of the efficient and inorganic thermal-insulation mortar are greatly improved, and the effect of the thermal-insulation mortar is improved.

Description

technical field [0001] The present invention relates to a kind of mortar, especially a kind of thermal insulation mortar, specifically a kind of high-efficiency thermal insulation mortar. technical background [0002] With the promotion of building energy conservation by legislation in our country, building energy-saving materials are also becoming more and more abundant. Among them, thermal insulation mortar is more and more used for energy-saving maintenance of internal and external walls of buildings due to its good thermal insulation effect, high flame resistance level, and large safety factor. The production technology of thermal insulation mortar is also increasing year by year, but to solve the water retention and thixotropy of thermal insulation mortar, cellulose derivatives such as methyl cellulose (MC) and hydroxypropyl methyl cellulose have always been used (HPMC) based. The above materials play an indispensable role in improving the water retention and thixotrop...
