摘要：

In the experiment, polystyrene particles were used as lightweight aggregate to prepare lightweight composite insulation board which was mixed with fibers and waterproofing agent. The effect of water-cement ratio and volume ratio of polystyrene particles and cement on the density and mechanical properties of polystyrene insulation board was researched. And styrene-acrylic emulsion, stearic acid emulsion and composite emulsion waterproofing agent were used respectively to modify the waterproof of insulation board. Besides, the underlying action mechanism was explored. The results show that the optimum volume ratio was 5: 1, and the optimum water-cement ratio was 0.45. And when the content of composite emulsion waterproofing agent was 8%, the 2h and 24h water absorption were 6.0% and 8.1% respectively.
