Nano-perlite thermal insulation mortar and preparation method thereof
The invention belongs to the field of building materials, and specifically discloses nano-perlite thermal insulation mortar and a preparation method thereof. The thermal insulation mortar is prepared from sulphate aluminium cement, coal ash, nano-perlite, silica fume, redispersible emulsion powder, hydroxypropyl methyl cellulose ether, polypropylene fibres and a water reducer, wherein thermal insulation aggregates are prepared from the nano-perlite on the basis of a vacuum dipping adsorption process, and normal-pressure classifying and drying. The mortar disclosed by the invention is low in heat conductivity coefficient and high in strength, and realizes the optimal unification of the strength and the thermal insulation; the mortar disclosed by the invention is an inorganic material, achieves level-A fire resistance, has the performances of seepage prevention, corrosion prevention, high bonding strength, good weather resistance, stable and durable performances, no toxicity and harm, and the like, and can keep good thermal insulation in the whole life cycle of a building, thus effectively reducing the energy consumption of the building, increasing the use efficiency of energies, and meeting the requirements of energy conservation and emission reduction of buildings in China.
