High thermal insulation sandwich building wall foaming mortar and preparation method thereof

Abstract

The invention relates to sound insulation and thermal insulation material, in particular to high thermal insulation sandwich building wall foaming mortar and a preparation method thereof. The high thermal insulation sandwich building wall foaming mortar comprises 100-155 parts of ordinary portland cement, 9-17 parts of rapid hardening sulphate aluminium cement, 130-200 parts of coal ash, 6-15 parts of silica fume, 0.2-1 part of lithium carbonate, 1-5 parts of zinc stearate, 0.1-0.8 part of rubber powder, 0.6-1.5 parts of engineering fiber, 100-155 parts of water, 0.1-1.2 parts of water reducer, and 5-16 parts of hydrogen peroxide. According to the high thermal insulation sandwich building wall foaming mortar and the preparation method, the pouring effect of the motor is good, the problem of dead angle is solved, the material performance is stable, the life is long, ageing resistance is realized, the efficacies of inflaming retarding and fire prevention are achieved, the thermal insulation effect is good, the aim of energy conservation and environment protection is achieved, and the motor is a non-toxic and non-pollution green product, is simple in preparation process, is easy to operate, is less affected by external factors, and is wide in applicable range.

Description

technical field [0001] The invention relates to heat-preservation, sound-insulation and heat-insulation materials, in particular to foamed mortar for high heat preservation sandwich building walls and a preparation method thereof. Background technique [0002] The use of thermal insulation walls has been gradually promoted, and plastic foam is used more often, such as: the use of thermal insulation layers of external walls of buildings, walls of simple houses, etc. More and more attention has been paid to the thermal insulation wall, mainly because the thermal insulation wall has enough heat insulation, making the room warm in winter and cool in summer, energy saving and environmental protection, but the materials used in the thermal insulation wall are not satisfactory. Take the plastic foam with a high adoption rate as an example. The plastic foam has a low service life and is easy to age. During installation, each piece needs to be butted together. After a long time, ther...

Problems solved by technology

More and more attention has been paid to the thermal insulation wall, mainly because the thermal insulation wall has enough heat insulation, making the room warm in winter and cool in summer, energy saving and environmental protection, but the materials used in the thermal insulation wall are not satisfactory

Take the plastic foam with a high adoption rate as an example. The plastic foam has a low service life and is easy to age. During installation, each piece needs to be butted together. After a long time, there will be gaps at the aging butt joints of the plastic foam, and the phenomenon of anti-frost and anti-dew will appear. , so that the effect of thermal insulation is reduced, it is easy to burn and emits toxic gas, once a fire occurs, the toxic smoke will seriously endanger people's lives
