Low-thermal conductivity thermal-insulation mortar
The invention discloses a low-thermal conductivity thermal-insulation mortar, and belongs to the technical field of building material. The low-thermal conductivity thermal-insulation mortar comprises following ingredients, by mass, 15 to 35% of PO.42.5 cement, 20 to 40% of type I glass bead, 20 to 40% of type II glass bead, 1 to 5% of high-performance hollow ceramic microbead, 1 to 4% of a modification auxiliary agent, 2 to 6% of multifunctional fiber, 1 to 3% of polymer latex powder, 0.5 to 2% of cellulose ether, 0.1 to 0.4% of a high-efficiency water reducing agent, 0.2 to 0.8% of an air entraining agent, 0.1 to 0.4% of organic silicon water repellent agent, and 1 to 3% of wood fiber polymer latex powder. According to the low-thermal conductivity thermal-insulation mortar, high-performance hollow ceramic microbead is added, so that product thermal insulation performance and workability are improved, mixing uniformity of the ingredients of the low-thermal conductivity thermal-insulation mortar is improved, breakage rate of glass bead is reduced greatly, fiber using amount is increased, high performance of the low-thermal conductivity thermal-insulation mortar is ensured, and product stability and quality are improved.
