The highly weather-resistant polymer rubber-plastic blend waterproof coiled material and preparation method according to claim 3, characterized in that: In step S3, the set temperature of the twin-screw extruder is 170° C.-185° C., the temperature is increased successively, the mold set temperature is 185° C., and the frequency of the twin-screw extruder is controlled at 35 Hz.

5. The highly weather-resistant polymer rubber-plastic blend waterproof coiled material and preparation method according to claim 4, characterized in that: The specific steps of step S4 are: according to the 1.5mm thickness requirement, the roller gap of the vertical three-roller mill is adjusted to 1.3mm, the membrane is put into the vertical three-roller mill for calendering, cooling and shaping, and the vertical three-roller speed is controlled to 3.5m / min. After the membrane exits the vertical three-roller mill, it enters the six-roller tempering device. The surface temperature of the six rollers heats the sheet again to accelerate the stress release of the sheet. After exiting the tempering device, it enters the cooling rack under traction for natural cooling.

6. The highly weather-resistant polymer rubber-plastic blend waterproof coiled material and preparation method according to claim 5, characterized in that: In step S4, the setting temperature of the vertical three-roll mill is 40°C, and the setting temperature of the six-roll tempering device is 70°C.
