摘　　要：In order to decrease the hygroscopicity of medium-density fiberboard(MDF)and improve the waterproofing and moistureproofing performance of the fiberboard,a reactive waterproofing agent composed of mainly organic-silicon was prepared.The paper discusses the influence of different concentrations of the reactive waterproofing agent on the waterproofing and mechanical properties of the fiberboard.The result of this examination showed that a suitable concentration range of the reactive waterproofing agent could largely decrease the thickness swelling rate and the water absorption rate of the fiberboard,and could also enhance the dimensional stability and quality of the fiberboard.In order to decrease the hygroscopicity of medium-density fiberboard（MDF）and improve the waterproofing and moistureproofing performance of the fiberboard,a reactive waterproofing agent composed of mainly organic-silicon was prepared.The paper discusses the influence of different concentrations of the reactive waterproofing agent on the waterproofing and mechanical properties of the fiberboard.The result of this examination showed that a suitable concentration range of the reactive waterproofing agent could largely decrease the thickness swelling rate and the water absorption rate of the fiberboard,and could also enhance the dimensional stability and quality of the fiberboard.
