Problems solved by technology

[0002] At present, the use of modular production of building panels is more and more popular. Modular production of panels has brought a new revolutionary impact on the construction industry, reducing construction costs and greatly shortening the time for building houses. However, modular production After a period of time, there will be pan-alkali on the surface of the cement board, and a large area of ​​hoarfrost will appear. The reason for this is that the ingredients and proportions of the formula are not appropriate. When encountering air oxidation, white powdery substances are produced, and the internal components of the material decompose and bloom, etc. The surface of the cement board with efflorescence affects the water absorption rate, poor corrosion resistance, poor water resistance, poor seepage resistance, shortened service life, affects the appearance, reduces the adhesion between the paint and the board, and affects the use

Abstract

The invention belongs to the technical field of building material coating, and particularly relates to a saltpetering-prevention sulphoaluminate cement product and a preparation method thereof. The saltpetering-prevention sulphoaluminate cement product is characterized by being prepared from the following ingredients in parts by weight: 50 to 80 parts of sulphoaluminate cement, 8 to 15 parts of fly ash, 7 to 12 parts of silica fume, 8 to 12 parts of glass fiber, 30 to 90 parts of water, 2 to 5 parts of retarding agents, 3 to 5 parts of water retention agents, 3 to 5 parts of thickening agnets and 5 to 8 parts of saltpetering inhibitors. The saltpetering-prevention sulphoaluminate cement product has the advantages that the formula is reasonable; the use is convenient; the surface of the saltpetering-prevention sulphoaluminate cement product is smooth; anti-seepage performance and water-resistant performance are good; saltpetering cannot occur in the long-time use process.
