[0053] In the embodiment of the present invention, the preparation method of the self-adhesive modified bitumen waterproof membrane coating material comprises:
[0054] Heat the mixed asphalt to a molten state, control the system temperature at 140°C, add polyethylene wax and stir evenly; control the system temperature ≤ 150°C, add stabilizers, and react for 30 minutes; control the system temperature at 150°C, add powder SBR modification in turn agent and linear SBS modifier; control the temperature of the system at 180°C, after the powder SBR modifier and linear SBS modifier are completely swollen, add tackifying resin, and after complete dissolution, add inorganic filler and stir evenly to obtain the described Self-adhesive modified bitumen waterproof membrane coating material. Among them, the preparation method of the mixed asphalt is as follows: below 160°C, add 90# petroleum asphalt and minus three softening oil in sequence, and stir slowly for 5min-10min below 160°C, so ...
