Abstract

The invention relates to a geopolymer-based thermal insulation mortar with water resistance and fire resistance. The geopolymer-based thermal insulation mortar comprises, by weight, 96.2 to 112.1 parts of an aluminum silicon material, 28.4 to 33.1 parts of an alkali activator, 66.0 to 77.0 parts of a modified lightweight aggregate, 12.2 to 14.2 parts of a polymer emulsion, 0.2 to 0.4 part of a toughening component, 5.2 to 6.0 part of an additive, and 82.8 to 107.5 parts of water; and 0.28 to 0.42L of foam is added into each one kilogram of a mixture of the above raw materials. The geopolymer-based thermal insulation mortar possesses high consistence retention rate, low layering degree, low dry density, high strength, excellent water resistance, A grade fire resistance, excellent thermal insulation performance, and excellent cracking resistance; the service life of the geopolymer-based thermal insulation mortar is as long as that of buildings; and the geopolymer-based thermal insulation mortar is especially to be used for building exterior wall external thermal insulation.

Description

technical field [0001] The invention belongs to the field of building materials and relates to a thermal insulation mortar, in particular to a geopolymer-based thermal insulation mortar with waterproof and fireproof functions. Background technique [0002] At this stage, the insulation materials of the exterior walls of buildings that have undergone thermal insulation treatment in my country basically use organic thermal insulation materials. Although the existing organic thermal insulation materials have excellent thermal insulation properties, they are greatly limited in use due to their poor fire performance and cannot meet the fire safety requirements of buildings. Due to its stable physical and chemical properties, good fire performance and good thermal insulation performance, inorganic fireproof and thermal insulation materials overcome the technical defects that the fire protection level of general organic thermal insulation materials does not meet the requirements, a...
