Hunan cps reactive viscosity Waterproof roll It is based on resin polymer（ EVA 、 LDPE 、 HDPE , ECB, etc.) as the main waterproof material, the polymer waterproof substrate is covered with non asphalt Polymer self-adhesive waterproof roll based on self-adhesive adhesive. After the reaction and consolidation of coiled material self-adhesive layer and liquid concrete glue, the seamless combination of waterproof layer and concrete structure is formed, which can eliminate the hidden danger of water channeling between layers and effectively improve the reliability of waterproof system.
Features of reactive adhesive waterproof membrane products
① SZ-CPR non asphalt based reactive polymer self-adhesive waterproof coiled material can be constructed on wet base, which is very suitable for underground waterproof engineering and is suitable for following the civil engineering progress.
② The good performance of SZ-CPR non asphalt based reactive polymer self-adhesive waterproofing membrane can be summarized as three "three".
Three "self"
Self adhesion: the non asphalt based self-adhesive adhesive reacts with the concrete or coating through the synergistic action of chemical coordination and physical penetration to form a dense and closed whole.
Self healing: The characteristic "self healing" function makes the local punctured damage points become better by themselves.
Self locking water: self-adhesive adhesive can lock the leakage point and prevent water channeling.
Three "resistance"
Tear resistance: the technology of cross laminating film makes this product have super horizontal and longitudinal tear resistance function.
Aging resistance: the raw material composition of non asphalt based self-adhesive adhesive and the anti direct light performance of cross laminated film determine that CPR non asphalt based reactive polymer waterproof coiled material can meet the design life requirements of basement and roof infrastructure, and solve the defect of short service life of traditional asphalt based coiled material.
High temperature resistance: the good low-temperature bending property makes this product suitable for use in various places or even in the climate with low temperature.
Three "high"
High peel strength: the peel performance of CPR non asphalt based reactive polymer waterproof coiled material is 2~3 times that of traditional asphalt based coiled material. It is closely combined with concrete and paint to create an external waterproof barrier for buildings.
High elongation: the product adopts cross laminated film technology, with high toughness, and the elongation is 7 times that of ordinary films.
High construction efficiency: the product has low requirements for the base course, and can be directly constructed on the wet concrete foundation; At the same time, the waterproof effect is good. One layer is paved and two layers are fortified, which not only saves costs, but also greatly shortens the construction period and improves the construction efficiency.
Reaction adhesive waterproof roll construction technology
1. Clean the surface of the base course. The base course can be wet, but there is no open water. During the construction of wet paving method, the dry base course needs to be watered; During the construction of dry paving method, the base treatment agent can be directly painted on the dry base.
2. During the plane waterproof construction, it is required to carry out trial paving of coiled materials. The coiled materials shall be paved horizontally at one time, and the longitudinal overlapping width of coiled materials and coiled materials shall be 80mm, and the transverse overlapping width shall be 100mm, so that the coiled materials can be paved neatly and lapped in a standard way, and then the coiled materials can be rolled once before entering the next step.
3. Ordinary Portland cement of no less than 32.5R shall be added with proper amount of water to make it gelatinous, and the water cement ratio shall be 0.4
4. Evenly apply the mixed cement slurry on the base course with a scraper, pave the waterproof coiled material on the surface of the base course while applying the cement slurry, and firmly paste it with exhaust roller.
5. Additional layer shall be added at the node according to the specification and design requirements. The additional layer can be self-adhesive coiled material and double-sided self-adhesive tape. The joint of coiled material end should be sealed with matching sealing paint
