Abstract

The invention provides a sulphoaluminate foamed cement heat insulation board with a good sound insulation effect. The sulphoaluminate foamed cement heat insulation board is prepared from the following components in parts by mass: 45-50 parts of sulphoaluminate cement, 1.5-1.8 parts of expanded perlite, 0.5-0.8 part of pottery clay, 8-10 parts of coal ash, 1.2-1.5 parts of gypsum, 0.6-0.8 part of polypropylene fiber, 1.8-1.0 part of calcium stearate, 0.2-0.4 part of sodium metasilicate, 2.6-2.9 parts of 35% hydrogen peroxide, 3-5 parts of a lithium-based curing agent and 42-46 parts of water. The invention also provides a preparation method of the sulphoaluminate foamed cement heat insulation board. The sulphoaluminate foamed cement heat insulation board provided by the invention is favorable in heat insulation and sound insulation effects and suitable for a heat insulation system for an exterior wall.

Description

technical field [0001] The invention relates to a sulphoaluminate foamed cement insulation board with good sound insulation effect. 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 the foamed cement directly affects various performance parameters of the foamed cement board, and the sound insulation effect of the existing sulphoaluminate cement insulation ...
