Self-adhesive waterproof material is a kind of self-adhesive rubber bitumen based on synthetic rubber such as SBS, tackifier and high-quality road petroleum asphalt. It has strong adhesive properties and self-healing properties, both at high temperatures. Environment, or low temperature environment can be construction. The following small series for everyone to introduce the characteristics of self-adhesive waterproof material and self-adhesive waterproof material construction precautions.
Self-adhesive waterproof material features
1, without adhesive, do not need to heat baked to melt, just torn off the isolation layer, can be firmly bonded to the base layer. The construction is convenient and the construction speed is extremely fast.
2, with rubber elasticity, excellent elongation, well adapted to the deformation and cracking of the base layer.
3, has excellent adhesion to the grass-roots level, the adhesion force is often greater than its shear force (bonding surface outside the fracture), to ensure that the lap is tight and reliable, seamless.
4. Unique “self-healing function†can self-heal smaller puncture damages, and when puncturing or hard objects are embedded, it will automatically integrate with these objects and maintain good waterproof performance.
5, construction safety, no environmental pollution, construction is simple and clean, easy to implement on-site civilized construction.
6, in addition to the main material, the surface material of polyethylene film also has excellent water resistance and high strength (polyethylene polypropylene film is waterproof only with this film), so waterproof has a dual insurance.
7. Corrosion resistance: The coil has good acid and alkali resistance, chemical resistance, and excellent aging resistance in various environments.
8, construction safety, no pollution, the construction is simple and clean, easy to implement on-site civilized construction.
9, corrosion resistance: The membrane has good acid, alkali, chemical corrosion (except for the surface of the aluminum foil coil), with excellent aging resistance in various environments.
10. Waterproofing for roofs, basements, interiors, municipal works and reservoirs, swimming pools and subway tunnels in industrial and civil buildings. Also suitable for waterproofing of wooden and metal structural roofs. It is especially suitable for waterproofing projects such as oil depots, chemical plants, textile mills, and grain warehouses that are not suitable for open flames.
Self-adhesive waterproof material construction precautions
1. The quality of the grassroots directly affects the quality of the waterproofing of coiled materials. The base surface must be solid, smooth, clean, dry, free of loose pockmarks, no floating and miscellaneous dirt; the yin and yang angles are made straight and rounded.
2. Before the construction of the waterproof layer, it is necessary to install and fix the through-wall or through-hole pipelines and embedded parts, so as to avoid damaging the waterproof layer and causing leakage hazards after the waterproof layer is constructed.
3, when brushing the primary treatment agent to force thin coating, uniform thickness, does not leak the bottom, do not pile up. After the primary treatment agent is dried, the material must be applied in a timely manner. Otherwise, excessive dust must be applied again.
4. The lap joints between the short-edge seams of the two adjacent webs in the same layer and the upper and lower two-layer webs should be staggered by 1/3-1/2 widths, so as not to overlap the multi-layer joints and make the webs. Paste uneven clothes.
5. When pasting large-surface coils, do not remove the transparent insulating film on the backside of the coil prematurely to avoid contaminating the adhesive layer or mis-adhesion. If there is contamination on the surface of HDPE film that needs to be adhered to the coil, it can be cleaned with a special primer treatment agent.
6. Avoid the construction of bad weather such as rain and snow and winds above grade 5.
7. When the construction is completed and the acceptance has been passed, it shall be concealed in time. If it cannot be concealed in time due to special circumstances, effective temporary protection measures shall be taken.
Editor's summary: On the characteristics of self-adhesive waterproof material and self-adhesive waterproof material construction precautions are introduced here, and hope to be helpful to everyone. If you want to know more about yourself, you can follow the information on this site.
