Abstract

The invention discloses sulphoaluminate foaming cement. The cement comprises, by weight, 42-45 parts of sulphoaluminate cement, 5-10 parts of silicate cement, 10-14 parts of coal ash, 0.3-0.5 part of polypropylene fiber, 0.9-1 part of calcium stearate, 3-3.2 parts of aquae hydrogenii dioxide with concentration of 27.5%, 3-6 parts of a lithium-based curing agent and 38-45 parts of water. The silicate cement is added, the setting time is reduced, good foaming is achieved, and a produced insulating plate is good in heat-preservation and insulation effect.

Description

technical field [0001] The invention belongs to the field of cement, and in particular relates to a sulfoaluminate foamed cement. Background technique [0002] Foamed cement insulation board is currently the most ideal insulation material for wall insulation and wall insulation fireproof isolation belt. It has low thermal conductivity, good insulation effect, non-combustible, waterproof, strong adhesion to the wall, high strength, and non-toxic Radioactive material, environmental protection. It is in the same period as the service life of the building, and the construction is simple and fast. The technical performance is superior to wall insulation materials such as foam glass, foam ceramics, phenolic foam board, polystyrene particles, polystyrene board, and extruded board. [0003] The formula of foamed cement directly affects various performance parameters of the foamed cement board. When the existing sulfoaluminate cement is used to prepare foamed cement, there is a pro...
