The invention relates to a preparation method of an anti-
corrosion self-
adhesive polymer modified
asphalt waterproof coiled material. The preparation method comprises the following steps: S1, preparing jelly; S2, preparing a modified
asphalt layer; S3, starting a spraying device by the
control unit to spray the jelly obtained in the step S1 on the modified
asphalt layer in the step S2 to form a spraying layer, and when the spraying layer is sprayed to a preset thickness, obtaining an
adhesive layer; and S4, applying a PET film to the
adhesive layer in the step S3, and flattening, through a roller, and coiling the adhesive layer, and packaging the adhesive layer in a sealed mode. The
control unit compares the actual spraying layer increasing thickness with the preset spraying layer increasing thickness, the spraying frequency of the spraying
assembly and the rotating speed of the driving
assembly are adjusted according to the comparison result, the spraying process is precisely controlled through the
control unit, and therefore the increasing thickness of the spraying layer meets the preset standard after spraying every time, while the spraying efficiency is improved, the waste of materials can be effectively avoided, and the quality of the waterproof coiled material is further ensured.
