Abstract

The invention discloses insulating mortar for buildings and a preparation method thereof, relating to the technical field of novel building materials. The mortar is prepared from the following raw materials: carbide slag, boric sludge, modified shale pottery sand, Zuoyun clay, sepiolite fibers, microcline powder, analcite powder, calcium nitrite, polydimethylsiloxane, dimethyl sulfoxide, woody sodium carbonate, dehydroacetic acid, a polyacrylate co-polymerized emulsion, a waterproof agent, an anti-freezing agent, a thickening time control agent and an air entraining agent. The preparation method comprises the following step of stirring, mixing and grinding raw materials. The insulating mortar for buildings is simple and convenient in preparation method, has the characteristics of being high in compressive strength, good in impact toughness and excellent in waterproof and anti-freezing property, is insulative and soundproof, weather-resistant and resistant to weather, long in service life and wide in application occasion, the safe reliability of the insulating mortar structural body for buildings is improved greatly, and the mortar is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to the technical field of new building materials, in particular to a thermal insulation mortar for building and a preparation method thereof. Background technique [0002] With the rapid development of society and the continuous improvement of people's living standards, energy consumption is becoming increasingly severe. How to efficiently save energy and reduce energy consumption has become the key to solving energy problems. In my country, building energy consumption has accounted for 46.7% of the total energy consumption of the whole society, which directly affects the sustainable development of my country's social economy, and improving the thermal insulation performance of buildings is the key to reducing building energy consumption. Therefore, research and development of building wall Insulation materials are of great significance. [0003] Building thermal insulation mortar reduces building energy consumption by improving t...
