Embodiment 1
[0065] Example 1 Anti-adhesive waterproof board
[0066] An anti-adhesive waterproof board, which is composed of a substrate layer, a self-adhesive layer and an isolation film layer sequentially combined, and the self-adhesive layer is arranged between the base material layer and the isolation film layer; the base material The thicknesses of the self-adhesive layer, the self-adhesive layer and the isolation layer are 0.6-0.8mm, 0.2-0.3mm and 0.05-0.1mm respectively. See Table 1 for the raw material composition of the substrate layer, the self-adhesive layer and the isolation layer.
[0067] The above-mentioned anti-adhesive waterproof board is prepared by the following method:
[0068] I. Substrate layer extrusion calendering
[0069] Prepare each raw material according to the ratio shown in Table 1, put it into a high-speed mixer and mix evenly, transfer the mixed material to a single-screw extruder, extrude, draw, and then pass through a three-roll calender for calenderin...
