Abstract

The invention relates to bonding mortar used in a foam glass building heat insulation system. The bonding mortar consists of a dry material and an admixture. The bonding mortar is characterized in that the dry material consists of cement, fly ash, fine sand and coarse sand which respectively account for 20%-25%, 10%-15%, 45%-50% and 10%-20% of the total weight of the dry material; the admixture consists of dispersible emulsion powder, methyl cellulose ether and polyacrylamide which respectively account for 0.20%-0.25%, 0.03%-0.05% and 0.08%-0.10% of the total weight of the dry material. The bonding mortar has good mixture workability and high bonding strength, and is more applicable to the foam glass building heat insulation system in terms of the water resistance and the operable time.

Description

technical field [0001] The invention relates to a bonding mortar in a building heat preservation system, in particular to a bonding mortar used in a foam glass building heat preservation system. Background technique [0002] At present, with the increase of the country's building energy conservation efforts, the application of external wall insulation technology has also been enhanced, and its important component - bonding mortar has been widely used. [0003] Adhesive mortar is a kind of dry-mixed mortar prepared by mixing and homogenizing suitable polymer admixtures according to the needs of different thermal insulation systems, especially the different thermal insulation materials. Due to the addition of a certain polymer admixture in the adhesive mortar, it has good adhesion, water resistance and other properties. [0004] Traditional bonding mortars are usually divided into two types: single-component type and multi-component type. Single component means that the mort...
