Vitrified microballoon heat insulation anti-crack mortar

Abstract

The invention provides a vitrified micro bubble heat-insulating and crack-resistant mortar, which belongs to the technical field of building mortar. The invention overcomes the defects of the prior art and provides an nontoxic and harmless, heat-insulating, sound-insulating, crack-resistant building mortar with good strength properties, the specific technical proposal is that: the vitrified micro bubble heat-insulating and crack-resistant mortar is prepared by the following materials according to mass ratio: 45-50 parts of close-hole vitrified micro bubble, 40-45 parts of cement, 8-12 parts of additive; the additive is mixed by the following materials according to mass ratio: 48-55 parts of natural glue powder, 36-42 parts of cellulose, 3-5 parts of lignin and 2-4 parts of cement retarder. The mortar provided by the invention can be widely applied to the building field.

Description

technical field [0001] The vitrified microbead thermal insulation and anti-crack mortar of the invention belongs to the technical field of construction mortar. Background technique [0002] Traditional building mortar uses polystyrene particles and ordinary expanded perlite light-weight bone materials as the main raw materials for thermal insulation mortar. These expanded perlite light-weight aggregates have high water absorption and are easy to pulverize, and the slurry has a large volume loss rate during construction. , it is easy to cause low strength and hollow cracking in the later stage of the product, thereby reducing the insulation effect of the mortar; at the same time, the polystyrene particle organic material is flammable, has poor fire resistance, produces harmful gases at high temperatures, is easy to age, has low weather resistance, and is easy to burn. Poor performance, and large rebound in construction and other defects. Contents of the invention [0003] ...
