Method for preparing micro expanded inorganic heat insulation mortar

Abstract

The invention discloses a method for preparing micro expanded inorganic heat insulation mortar. Materials such as common silicate cement, desulfuration ash, calcium carbonate powder, re-dispersible latex powder, hydroxypropyl methyl cellulose ether, wood fiber, polypropylene fiber, surfactant, foam stabilizer, water, vitrified micro bubbles and the like are adopted; and the mortar is obtained by adopting the steps of stirring, mixing, shaping, curing and the like. The method has the advantages of low cost, early micro expansion, low later linear shrinkage rate, fire resistance, durability and the like, is easy to construct, and achieves good effect of preparing the I-type building heat insulation mortar by using the III-class vitrified micro bubbles.

Description

[0001] technical field

[0002] The invention belongs to the technical field of building energy-saving thermal insulation materials, and in particular relates to an inorganic thermal insulation mortar material used for building exterior walls.

[0003] Background technique

[0004] Building envelope insulation is usually divided into external wall thermal insulation system and external wall thermal insulation system. At present, new buildings mainly use external wall thermal insulation system. There are mainly four types of building external wall external thermal insulation systems: rubber powder polystyrene particle external wall external thermal insulation system, expanded polystyrene board thin plaster external wall external thermal insulation system, spray foamed polyurethane external wall external thermal insulation system, expanded vitrified micro Bead insulation mortar building insulation system.
