Abstract

The invention discloses internal wall thermal insulating mortar which is prepared from the following raw materials in parts by weight: 45-55 parts of slag cement, 3-6 parts of citric acid residue, 15-25 parts of quick lime, 10-15 parts of volcanic rock, 2-4 parts of asbestos fiber, 20-30 parts of hollow microsphere, 10-15 parts of calcined zeolite, 3-5 parts of soybean protein powder, 2-3 parts of sodium hexametaphosphate, 4-6 parts of guar gum powder, 2-3 parts of polyoxyethylene, 1-2 parts of sodium acetate, 2-3 parts of sugar calcium and 3-6 parts of composite packing. Compared with conventional thermal insulating mortar, the thermal insulating mortar disclosed by the invention has the characteristics of low volume-weight, high strength, stable thermal insulation property, freeze-thawing resistance, aging resistance, anti-cracking property, good anti-mold effect and the like, is green and environment-friendly, safe and reliable, simple and convenient to construct, low in cost, and can be widely applied to internal wall heat preservation systems.

Description

technical field [0001] The invention relates to an inner wall thermal insulation mortar, which belongs to the field of building materials. Background technique [0002] Insulation mortar is a kind of ready-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed by the production enterprise. It is used to construct the insulation layer of the building surface a building material. With the continuous promotion of low-carbon environmental protection and building energy conservation and the continuous improvement of people's demand for the comfort of the living environment, people pay more and more attention to thermal insulation mortar. Many applications, but compared with developed countries, the existing thermal insulation mortar for interior walls still has low strength, poor crack resistance, and is prone to problems such as hollowing and cracking. Contents of the invention [0003] The object...
