Embodiment 1
[0024] figure 1 The basic structure of the building's exterior wall interior insulation system is a gypsum-based insulation material. In order to ensure the uniformity and compatibility of the materials of the whole system, a new type of building insulation system is established on the basis of replacing cement base with gypsum base. This invention develops a crack-resistant gypsum-based plaster mortar for gypsum-based thermal insulation. The plastering layer of the thermal insulation system of the external wall of the building.
