Authorized document number: CN 1103131062B Authorized public date: May 3, 2017 Patentee: Hengshui Yu Li Engineering Rubber Co., Ltd. Inventor: Sun Zhiwei, Sun Zhiheng The present invention discloses a method for preparing a composite slow-swelling type water-stop rubber . The water stop rubber consists of an expanded portion and a composite portion. Among them, the expansion part of rubber from rubber, carbon black, bentonite, antioxidant, accelerator and expansive composition; composite part of rubber from rubber, carbon black, calcium carbonate, softener and accelerator composition. The preparation method of the water stop rubber is that: the expansion part and the compound part rubber compound are respectively mixed and then are extruded by extrusion. Compared with ordinary slow-swelling type water-stop rubber, the composite slow-swelling water-stop rubber of the present invention not only has good physical properties but also has a layer of water-permeable rubber
