High-performance thermal-insulation mortar

Abstract

The invention discloses a high-performance thermal-insulation mortar, and belongs to the technical field of external wall thermal-insulation mortar. The high-performance thermal-insulation mortar is composed of, by mass, 25 to 40% of PO.42.5 cement, 50 to 70% of glass microbead, 0.5 to 2% of high-performance hollow ceramic microbead, 1 to 1.5% of polypropylene fiber, 2 to 4% of polymer latex powder, 0.2 to 0.4% of cellulose ether, 0.1 to 0.3% of a high-efficiency water reducing agent, 0.1 to 0.2% of an air entraining agent, 0.1 to 0.2% of organic silicon water repellent agent, and 1 to 1.5% of wood fiber. The high-performance thermal-insulation mortar is a single-component light dry mortar specially used for external wall thermal-insulation surface layers; combustion performance is capable of reaching A-class non-combustible; the high-performance thermal-insulation mortar is capable of preventing flame spread effectively, is a thermal-insulation material with excellent performance, is capable of protecting internal thermal-insulation layers from aging and deformation effectively, and prolonging service life of thermal-insulation systems.

Description

technical field [0001] The invention relates to the technical field of thermal insulation mortar for external walls, in particular to a high-performance thermal insulation mortar. Background technique [0002] At present, the thin plastering system is mostly used for external wall insulation in China. It is to apply a crack-resistant protective layer on the surface of the insulation board, about 3-5mm thick, to protect the insulation material. Due to the thin anti-crack protection layer, there are many disadvantages: [0003] 1. Poor fire resistance, when a fire occurs, the insulation layer is extremely easy to burn; [0004] 2. Due to the thin anti-crack protective layer, it cannot protect the internal insulation material due to temperature stress caused by temperature changes, which will cause material deformation, resulting in cracking and water seepage of the insulation system. Contents of the invention [0005] The purpose of this invention is to provide a high-perf...
