Through cps, it is reflected that the active ingredients in the sealant and the cement gel in the hydration process have chemical crosslinking and physical tenon-mortise synergy, forming an "interpenetrating network" interface structure, thoroughly solving the problems of weak adhesion, non-lasting adhesion and easy environmental influence between ordinary coiled materials and the base surface, realizing the waterproof effect of irreversible and lossless adhesion between coiled materials and the base surface, and perfectly realizing the "skin-type" waterproof concept.
