摘要
水膨胀橡胶是目前地下工程中广泛应用的新型防水材料.但是,如何在有水的场合,防止其预膨胀是个悬而未决的难题.缓膨胀剂正是发挥这种延缓膨胀功能的专用涂剂.本文除了阐述缓膨胀剂的制备的技术性能指标外,着重探讨了有关应用技术.
water-expanding rubber is a new type of watrproof material used widely in underground engineeing. However,a difficult point remains to be solved, that is how to prevewt it from preexponding where water existing. Low expanding agewt is the key to it. The article describes its application as well as production and technical properties.
