Abstract:
      This paper explores the feasibility and influencing factors of preparing self-adhesive polymer modified asphalt waterproof membrane with rubber powder. The results show that 20% 60 mesh rubber powder can be used to prepare self-adhesive polymer modified asphalt waterproofing membrane to meet the requirements of GB23441-2009. Because the crosslinking of rubber powder limits the kinematic ability of molecular chain, it can not give full play to the characteristics of linearized rubber. In order to fully realize these characteristics, the feasibility of using activated rubber powder to prepare self-adhesive polymer modified asphalt waterproof membrane was explored. The results show that the activated rubber powder with activation degree of 50% can be used to prepare waterproof coil with excellent properties. The optimum proportion is 50% activated rubber powder, 6% SBS and 60% talc powder with 100% asphalt. Because the small molecular components in the activated rubber powder are similar to compatibilizers, macromolecular rubber components and toluene insoluble substances in the mechanism of action with SBS, the above-mentioned interaction can replace compatibilizers, rubber powder and most of SBS in the traditional scheme, and obtain excellent comprehensive physical properties
