Heat-preserving mortar for building wall body and preparation method for heat-preserving mortar

Abstract

The invention discloses heat-preserving mortar for a building wall body. The heat-preserving mortar comprises the following ingredients in parts by mass: 20-30 parts of cement, 10-15 parts of fly ash,30-40 parts of fine sand, 2-3 parts of redispersible latex powder, 0.5-1.2 parts of water reducer, 3-5 parts of heat-insulating lightweight aggregates, 1-2 parts of staple fibers, 2-3 parts of long fibers and 3-5 parts of mortar reinforcer. A preparation method for the heat-preserving mortar comprises the steps of carrying out material pretreatment and weighing sufficient amounts of fly ash, finesand, redispersible latex powder and heat-insulating lightweight aggregates. According to the heat-preserving mortar for the building wall body and the preparation method for the heat-preserving mortar, particle accuracy of each material can be strictly controlled, the staple fibers, the long fibers and the heat-insulating lightweight aggregates can be in full contact with the redispersible latexpowder, and after mixed forming, the staple fibers, the long fibers and the heat-insulating lightweight aggregates can be more tightly combined with the cement, the fine sand and the fly ash, so thatthe heat-insulating property and shear resistance of the mortar are greatly improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a thermal insulation mortar used for building walls and a preparation method thereof. Background technique [0002] Buildings generally need to carry out the construction of insulation layer. The traditional thermal insulation materials are expanded polystyrene board, extruded polystyrene board and foamed polyurethane, etc. Although their thermal conductivity is small and their thermal insulation performance is excellent, as an organic thermal insulation material, their fire performance is poor. In recent years, my country has experienced There have been many serious fires caused by the ignition of organic thermal insulation materials. Therefore, many areas have begun to vigorously promote inorganic thermal insulation. [0003] The existing building thermal insulation mortar only mixes various mortar raw materials during use, and cannot exert the best performance of th...

Problems solved by technology

The traditional thermal insulation materials are expanded polystyrene board, extruded polystyrene board and foamed polyurethane, etc. Although their thermal conductivity is small and their thermal insulation performance is excellent, as an organic thermal insulation material, their fire performance is poor. In recent years, my country has experienced There have been many serious fires caused by the ignition of organic thermal insulation materials. Therefore, many regions have begun to vigorously promote inorganic thermal insulation materials.

[0003] Existing building thermal insulation mortars only mix and stir various mortar raw materials during use, and cannot give full play to the best performance of thermal insulation mortars.
