Vitrified particulate heat-insulated material for walls

Abstract

The invention discloses a vitrified particular heat-insulated material for walls, belonging to the field of construction materials. The vitrified particular heat-insulated material for the walls comprises the following components in parts by weight: 100-150 parts of vitrified micro particle, 30-50 parts of expanded perlite, 30-60 parts of cement, 30-60 parts of sodium silicate, 1-10 parts of a hardener, 1-10 parts of a hydrophobic agent and 1-10 parts of a penetrant. The vitrified particulate heat-insulated material for the walls has the advantages of high density, high compressive resistance, low thermal conductivity, good heat-insulated effect and the like, has fire-protection rating A, and is a fireproof and heat-insulated material with excellent comprehensive performance.

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...

[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
