Example Embodiment
[0028] Example one see figure 1 :This kind of wet-adhesive self-adhesive waterproof membrane 1 is sequentially laminated with the following layers: isolation layer 11, self-adhesive sealing layer 12, polymer waterproof sheet 13, adhesive layer 14, flexible protective layer 15, the above-mentioned flexible protection The sling 16 is worn on the layer, and both ends of the sling are exposed for lashing.
[0029] The self-adhesive sealing layer 12 has self-healing properties, cold construction, no solvent volatilization, safety and environmental protection, no fire hazard, convenient construction, and can be bonded in a humid environment or in water. The material of the polymer waterproof sheet 13 can be high-density poly Ethylene HDPE, low-density polyethylene LDPE, polyvinyl chloride PVC, polyvinyl acetate EVA, ethylene, vinyl acetate asphalt blend ECB or modified asphalt coils. The thickness of the polymer waterproof sheet or modified asphalt coil is 0.5-2.0mm, and it has the fun...
Example Embodiment
[0030] See the second embodiment figure 2 : In the case of the front sticking construction, the non-woven fabric layer 15, the adhesive layer 14, and the strap 16 can also be omitted.
[0031] The material of the self-adhesive sealing layer is butyl rubber modified asphalt, and the weight ratio is as follows:
[0032] Butyl rubber 268; any value ranging from 8 to 28%.
[0033] High-quality oxidized asphalt: Any value from 30 to 50%.
[0034] Acrylic water-absorbing resin: Any value from 1 to 8%.
[0035] Operating oil: Any value from 5 to 35%, the operating oil can be naphthenic oil or three-line base oil.
[0036] Filler: Any value from 5 to 25%, the filler can be fossil powder or carbon black.
[0037] Flow-blocking agent: any value from 1 to 5%, the flow-blocking agent can be selected from the vapor-phase process white carbon black.
[0038] The production method of the above-mentioned wet-adhesive self-adhesive waterproof membrane is made by mixing butyl rubber and high-quali...
