Thermal insulation building mortar and preparation process thereof

Abstract

The invention discloses a thermal insulation building mortar. The thermal insulation building mortar is prepared by the mixing portland cement, pulverized fuel ash, calcium bentonite, re-scattering glue powder, hypromellose, polyacrylamide powder, polypropylene fibre, wood fiber, permeating crystal waterproof agent, air entraining agent, vitrified micro-bead, sizing phase-change material and hollow glass bead. A preparation process thereof comprises the steps of: a) preparing the sizing phase-change material, b) preparing the permeating crystal waterproof agent and c) preparing the thermal insulation building mortar. The mortar of the invention is characterized by the functions of thermal insulation, phase-change energy storage, temperature control, water resistance and energy saving, the wide application scope and low cost. The mortar is widely applied in thermal insulation work inside or outside the buildings and has a broad prospect.

Description

[0001] Field of invention [0002] The invention relates to the technical field of building materials, in particular to a thermal insulation building mortar and a preparation process thereof. Background technique [0003] In the building construction industry, building mortar is one of the important building materials in building construction, and its usage is quite large. The performance of construction mortar directly affects the quality of buildings. Today, when the global thermal effect is intensified, energy conservation and emission reduction are common problems faced by the construction industry in the world. my country has included the issue of building energy conservation in building regulations in the form of legislation. enforced. At present, the performance requirements for thermal insulation of building mortar are getting higher and higher. In recent years, vitrified microbead thermal insulation mortar has been widely used as the insulation layer in the building...

AI Technical Summary

Problems solved by technology

In recent years, vitrified microbead thermal insulation mortar has been widely used as the insulation layer in the building exterior wall insulation projects in hot summer and warm winter and hot summer and cold winter regions in my country. Although vitrified microbead thermal insulation mortar has the advantages of simple construction, no air Cavity, good integrity, high compressive strength, excellent crack resistance, small thermal conductivity, good fire resistance, etc., but its thermal insulation and water resistance are not good, the scope of application is small, and it is difficult to adapt to cold regions and Requirements for High Energy Saving Rate of Buildings
