The technical scheme of the utility model is as follows:
the utility model provides a water waterproofing membrane is scurry in no suitable for wet shop, includes child base, locates the upper adhesive layer and the lower adhesive layer of child base upper and lower surface, and its technical essential is: the tire base is filament polyester felt, the upper adhesive layer is SBS elastomer modified asphalt adhesive layer, the upper surface of the upper adhesive layer is provided with a slate layer composed of mineral grains and a sand-free surface with a preset width is reserved at one end of the coiled material, the lower adhesive layer is self-adhesive layer suitable for wet paving, and the lower surface of the lower adhesive layer is covered with an anti-adhesive layer.
The waterproof coiled material suitable for wet paving and free of water channeling is characterized in that the second anti-adhesive film is a silicone oil polyethylene anti-adhesive film.
The width of the sand-free surface of the waterproof coiled material suitable for wet paving is 80-100 mm.
The thickness of the waterproof coiled material suitable for wet paving is 3mm-5mm.
The ratio of the thickness of the SBS elastomer modified asphalt adhesive layer to the thickness of the self-adhesive layer is 1:1.5-1:2.
the beneficial effects of the utility model are as follows:
1. the lower surface of the tire base is constructed by adopting a self-adhesive layer and a wet paving method, the self-adhesive layer can form a technical effect of fully adhering and preventing water channeling with a base surface, and the self-healing property of the self-adhesive layer is strong, so that the self-adhesive layer has a good sealing function on tiny cracks of a base layer due to structural settlement, a complete waterproof system which is closely and inseparable is formed between materials and a building structure, the waterproof effect is good, and the high leakage rate of a roof waterproof engineering is guaranteed.
2. The SBS elastomer modified asphalt adhesive layer is adopted on the upper surface of the tire base, so that the use conditions of high temperature resistance, ageing resistance and ultraviolet resistance are met, the tire base does not flow or drip at the highest temperature of 105 ℃, and the slip is less than 2 mm; the low-temperature flexibility is minus 25 ℃ and has no crack; the anti-aging and anti-ultraviolet performance is strong. The plate rock layer is matched, so that a protective layer can be prevented from being beaten, and the plate rock can be directly exposed to sunlight for use.
3. The base adopts filament polyester felt, and has super tensile property and thermal dimensional stability.
4. The whole coiled material is simple and easy to operate in construction, time and labor are saved, the construction period is shortened, and the cost is saved.
