Problems solved by technology

[0003]Most of the current thermal insulation materials use ordinary expanded perlite and polystyrene particles as lightweight aggregates for dry-mixed thermal insulation mortar, but expanded perlite has high water absorption and is easy to powder The volume shrinkage rate is large during slurry mixing, which may easily cause low strength and hollow cracking in the later stage of the product, while the polyphenylene particle organic material has the characteristics of flammability, poor fire resistance, harmful gas generation at high temperature, and low aging and weather resistance. Due to defects such as high resilience during construction, the comprehensive performance and construction performance of thermal insulation mortar need to be further improved

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a vitrified microbead wall thermal insulation material. Background technique [0002] The advent of the energy crisis in the century and the mandatory implementation of building energy-saving policies have promoted the rapid development of building insulation materials. [0003] Most of the current thermal insulation materials use ordinary expanded perlite and polystyrene particles as lightweight aggregates for dry-mixed thermal insulation mortars, but expanded perlite has high water absorption and is easy to pulverize, and its volume shrinkage rate is large during slurry mixing, which is easy to cause product damage. Low strength and hollowing and cracking in the later stage, while polyphenylene particle organic materials have defects such as flammability, poor fire resistance, harmful gases generated at high temperature, low aging and weather resistance, and large...
