Abstract

The invention relates to an inorganic ultra-light cement foamed fireproof insulation board and a preparation method for the same. The insulation board is prepared from, by weight, 30-40 parts of ordinary Portland cement, 5-15 parts of high-alumina cement, 5-15 parts of CaO, 5-10 parts of coal ash, 4-6 parts of methylcellulose, 3-5 parts of ammonium chloride and 3-6 parts of foaming agent. The insulation board is obtained by means of dosing, mixing, injection molding and hardening. The inorganic ultra-light cement foamed fireproof insulation board is good in fireproofing, combustion-supporting performance and thermal insulation, the apparent dry density is 100-200kg/m3, the compression strength is 0.15-0.70 MPa, coefficient of heat conductivity is 0.038-0.08w/m k, and the insulation board is light in weight with the combustion performance being capable of meeting national level A1 standard, and can meet 65% of national energy-saving requirements.

Description

technical field [0001] The invention relates to a building material, in particular to an inorganic ultra-light cement foamed fireproof and heat preservation board and a preparation method thereof, which are mainly used for fireproof and heat preservation of outer walls or partitions of inner walls. Background technique [0002] At present, 90% of building exterior wall insulation board materials are organic combustible materials, including polystyrene board, extruded board and polyurethane foam board, which are extremely flammable in nature, aging quickly, and the fire spreads quickly when burning. In addition, due to the difference between the material of the board and the wall, it is easy to cause hollowing due to thermal expansion and contraction after pasting, forming a cavity. When the temperature reaches above 250°C, it will still burn and release a large amount of toxic and harmful black smoke. With more and more high-rise buildings, the ladder of fire trucks is gene...
