Magnesium phosphate cement-base porous material and preparation method thereof
The invention discloses a magnesium phosphate cement-base porous material and a preparation method thereof. The preparation method is characterized by comprising the following steps: taking the following raw materials in parts by mass: 5-40 parts of dead burnt magnesite, 10-35 parts of ammonium dihydrogen phosphate, 2-15 parts of borax, 10-60 parts of fly ash, 10-60 parts of quartz sand, 0.3-1 part of metallic zinc or iron powder and 5-20 parts of water; uniformly mixing the dead burnt magnesite, ammonium dihydrogen phosphate, borax, fly ash, quartz sand and metallic zinc or iron powder to obtain a powder mixture; adding the powder mixture into a container with a stirring device, adding water while starting time keeping, stirring slowly for 15-30 seconds, stirring quickly for 1.5-3 minutes, stopping stirring for 15 seconds, and stirring quickly for 3-5 minutes to obtain a slurry; and forming the slurry, and curing to obtain the magnesium phosphate cement-base porous material. The porous material disclosed by the invention has the advantages of early strength, quick hardening, favorable acid/alkali attack resistance, favorable thermal-insulation property, low carbon and environment friendliness, and is mainly used as a thermal-insulation material.
