High-heat-insulation sandwich construction wall cement foam and preparation method thereof

Abstract

The invention relates to a high-heat-insulation sandwich construction wall cement foam and a preparation method thereof. The foam is prepared through using fast-hardening sulphoaluminate cement, ordinary Portland cement, fly ash, silicon ash, lithium carbonate, calcium stearate, methyl cellulose, dispersible latex powder, engineered fibers, a water reducer, water and hydrogen peroxide. The high-heat-insulation sandwich construction wall cement foam has the advantages of good concreting effect, no dead angle problems, stable performances, long life, ageing tolerance, flame retardation and fire prevention, good heat insulation effect, energy saving, environmental protection, non-toxicity, and no pollution; and the preparation method has the advantages of simplicity, easy operation, small influence of external factors, and wide application range.

Description

technical field

[0001] The invention relates to building materials, in particular to a high thermal insulation sandwich building wall cement foam and a preparation method. Background technique

[0002] The use of thermal insulation walls has been gradually promoted, and plastic foam is used more often, such as: benzene boards used on walls such as the thermal insulation layer of the outer walls of buildings and simple houses. More and more attention has been paid to the thermal insulation wall, mainly because the thermal insulation wall has heat insulation, which makes 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 benzene board with a high adoption rate as an example. The life of the benzene board is low and it is easy to age. During installation, each piece needs to be butted together. After a long time, the plastic foam will age and gaps will appea...
