Abstract

The invention discloses insulated crack-resistant protective light dry mortar for external thermal insulation of an exterior wall. The insulated crack-resistant protective light dry mortar comprises the following raw materials by mass percent: 25-35% of cement, 15-25% of vitrified microbead, 8-15% of quartz powder, 5-10% of coal ash floating bead, 1-5% of perlite, 5-15% of rubber particles, 3-10% of metakaolin, 1.0-1.5% of rubber powder, 0.1-0.3% of water reducing agent, 0.2-0.5% of anti-crack fiber, and 0.2-0.4% of cellulose ether, wherein the sum of the components by mass percent is 100%. The preparation method of the dry motor comprises the step of agitating and mixing the weighed raw materials. The using method comprises the steps of agitating and mixing water with the dry motor according to the mass ratio of (4-5):4. By adopting the insulated crack-resistant protective light dry mortar, rubber is added to cement-based crack-resistant protective dry mortar, so that the brittleness of the cement-based protective motor material is improved, the problems that the existing coating mortar is easy to crack and poor in durability are solved, and the thermal insulation and crack-resistant functions are really achieved.

Description

technical field [0001] The invention belongs to the technical field of building exterior wall materials, and in particular relates to a heat-insulating, anti-cracking and protective lightweight dry powder mortar for external wall insulation, and also relates to a preparation method of the dry powder mortar. Background technique [0002] The external thermal insulation system of building exterior walls can bring about excellent energy-saving effects and a comfortable living environment, so people pay great attention to the long-term performance of the system. The protective mortar used in the protective layer of the external wall thermal insulation system is mostly brittle cement-based material, which has a large specificity, high thermal conductivity, and high heat storage value; while the thermal insulation board is an organic thermal insulation material, which has a low density, soft texture, and large deformation. Under external erosion such as heat, cold and wet cycles, ...
