Novel heat-insulation dry powder mortar

Abstract

The invention belongs to the technical field of building materials, and discloses novel heat-insulation dry powder mortar. The mortar consists of portland cement, fly ash, vitrified beads, floating beads, heavy calcium, cellulose, latex powder and the like. Compared with conventional heat-insulation mortar, the novel heat-insulation dry powder mortar provided by the invention has the advantages of high strength, light weight, high bond strength and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a thermal insulation dry powder decorative material used for interior and exterior walls and roofs of buildings. When using it, you only need to add water at the construction site and stir it into a slurry with a certain consistency. Background technique [0002] With the shortage of energy and the enhancement of people's awareness of environmental protection, the status of energy conservation in the national economy will become higher and higher, and heat preservation and energy conservation are an important part of energy conservation. In recent years, with the improvement of people's living standards and the enhancement of comprehensive national strength, the construction of green ecological buildings with good thermal insulation, good ventilation, comfort, energy saving and consumption reduction has become more and more popular. Thermal insulation mate...

AI Technical Summary

Problems solved by technology

[0003] The current new type of thermal insulation dry powder mortar includes polystyrene particle thermal insulation mortar and expanded perlite thermal insulation mortar, but they have some disadvantages more or less, such as polystyrene particle thermal insulation mortar is flammable, poor fireproof performance, high temperature is easy to produce harmful gas and Poor workability, high resilience during construction, shrinkage and cracking, etc.

Expanded perlite thermal insulation mortar has the disadvantages of high water absorption rate, easy pulverization, large slurry shrinkage rate, low later strength and easy cracking.
