Abstract

The invention discloses vitrified microbead heat-preserving mortar. The vitrified microbead heat-preserving mortar comprises the following substances in mass percentage: 60-65% of cementing material, 30-35% of heat-preserving aggregate, 0.5-1% of redispersible latex powder and 1-1.5% of functional material. The vitrified microbead heat-preserving mortar is short in solidification time, good in fire-proof performance and heat-preserving effect and stable in construction performance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to vitrified microbead thermal insulation mortar. Background technique [0002] my country's external wall insulation includes organic insulation systems, inorganic insulation systems, and organic and inorganic composite insulation materials. Among them, organic insulation materials are mainly used. The production and construction technology is very mature, but they cannot be fireproof, pollute the environment, and are easy to age. Inorganic thermal insulation mortar materials have received widespread attention due to their low finished product, high strength, thermal insulation, fire resistance, weather resistance and other advantages, especially vitrified microbead thermal insulation mortar has great development prospects. [0003] However, the existing vitrified mortar has the disadvantage of slow setting due to the addition of wood fibers. Contents of the invention [0004]...
