Vitrified micro bubble thermal mortar aggregate and preparation method thereof

Abstract

The invention discloses a vitrified micro bubble thermal mortar aggregate and a preparation method thereof, and belongs to the field of thermal mortar aggregate construction and fabrication methods. The aggregate consists of aggregate particles, wherein each aggregate particle consists of a core layer and a wrapping layer; the core layers are polyphenyl particles of which the surfaces are subjected to high-temperature modification treatment; the wrapping layers are expanded and vitrified micro bubble thermal mortar; and the expanded and vitrified micro bubble thermal mortar is formed by uniformly mixing raw materials in parts by weight as follows: 25-30 parts of expanded and vitrified micro bubble, 40-48 parts of 325 cement, 15-20 parts of fly ash, 0.2-0.3 parts of PP (polyester) fiber, 0.2-0.3 parts of wood fiber, and 0.5-0.6 parts of emulsion powder. The aggregate is a novel thermal and heat insulated material which is good in flame retardancy, good in water resistance, high in durability, high-temperature resistant, nontoxic, and tasteless, and does not vitalize harmful substances.

Description

Technical field [0001] The invention relates to a building thermal insulation mortar material and a preparation method thereof, in particular to a vitrified microbead thermal insulation mortar aggregate and a preparation method thereof. Background technique [0002] At present, building thermal insulation mortar materials on the market generally use polyphenyl particles or ordinary expanded perlite as lightweight aggregates, and thermal insulation mortars that use polyphenyl particulate organic materials as lightweight aggregates are flammable, have poor fire resistance, and generate harmful gases and high temperatures. Defects such as low aging resistance and low weather resistance; the use of expanded perlite particles as lightweight aggregates has large water absorption, easy crushing, large volume loss during mixing, reduced product insulation performance in the later stage, and easy hollow drum cracking. At the same time, it makes up for the deficiencies of the polystyrene p...

AI Technical Summary

Problems solved by technology

[0002] At present, building insulation mortar materials on the market generally use polyphenylene particles or ordinary expanded perlite as lightweight aggregates, and thermal insulation mortars that use polyphenylene particle organic materials as lightweight aggregates are flammable, have poor fire resistance, and produce harmful gases at high temperatures. Defects such as aging resistance and low weather resistance; the use of expanded perlite particles as lightweight aggregates has disadvantages such as high water absorption, easy crushing, high volume loss rate during stirring, reduced thermal insulation performance of the product, and easy hollowing and cracking. At the same time, it makes up for the defects of poly-stupid particle organic materials such as flammability, poor fire resistance, harmful gas generation at high temperature, and low aging resistance and weather resistance.
