Problems solved by technology

The main insulation layer in the foam glass building insulation system is foam glass. Foam glass is an inorganic material with a rigid surface. When the traditional plastering mortar is used in the foam glass building insulation system, due to its large shrinkage and interface Due to weak penetration and other reasons, the bonding strength between the plastering mortar and the foam glass is low, and the foam glass cracks and other undesirable phenomena

Abstract

The invention relates to plaster mortar for a thermal insulation system of a foam glass building, which consists of dry materials and admixtures. The plaster mortar is characterized in that the dry materials consist of cement, fly ash and fine sand which account for 20 to 25 percent, 15 to 20 percent, and 55 to 60 percent of the total weight of the dry material respectively; and the admixtures consist of dispersible latex powder, hydroxypropyl cellulose ether, lignocellulose ether, polyacrylamide and anti-cracking fiber yarns which account for 0.30 to 0.35 percent, 0.03 to 0.05 percent, 0.02 to 0.03 percent, 0.08 to 0.1 percent, and 0.10 to 0.12 percent of the total weight of the dry material respectively. The plaster mortar has good workability of the admixture and high bonding strength,and is more suitable for the thermal insulation system of the foam glass building in water resistance, operable time and freeze-thaw resistance.

Description

technical field [0001] The invention relates to a plastering mortar in a building thermal insulation system, in particular to a plastering mortar used in a foam glass building thermal insulation 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 - plastering mortar has been widely used. [0003] Plastering mortar is usually a dry-mixed mortar prepared by mixing and homogenizing suitable polymer admixtures according to the needs of different insulation systems, especially the insulation materials. Since a certain polymer admixture is added to the plastering mortar, it has excellent properties such as good adhesion, water resistance, freeze-thaw resistance, and crack resistance. [0004] Traditional plastering mortars are usually divided into two types: single-component type and multi-component type....
