【 摘 要 】

In order to ensure the safety of the inorganic isolation partitioned polystyrene insulation board in applying, this paper studied its heat retention,flame retardancy, water absorption, fatigue performance, and microscopic analysis.The test results showed that the apparent density of the board is about 120kg/m3 would meet the demands of great flame retardancy and good thermal insulation; the volume water absorption rate is curve growing in the early stage, it drops slightly and keeping stable after reach the maximum, the maximum is less than 8%; after 1500 times 12.1KN/m2 impact on the board, the internal inorganic material is destroyed basically and remain unchanged in the substrate level; x-ray diffraction analysis result showed that there were Mg(OH)2 and hydrated magnesium sulfate in the solidified inorganic material.
