摘要：
Because of low strength, the expanded perlite insulation board's application in building energy saving is restricted. This paper discuss change rules of the expanded perlite insulation board apparent density and mechanical strength with adjusting the amount of sodium silicate, pressing pressure, heating system. It turned out that good thermal insulation performance and high strength expansion perlite insulation board is prepared by mass ratio of 2.5:1 of 30% of the content of solid sodium silicate solution to expanded perlite, 0.38MPa of pressing pressure and 105 degrees C condition of heating temperature.
