Description
Technical Field
The utility model relates to a building waterproofing membrane field, specifically speaking relate to a waterproofing membrane.
Background
The waterproof coiled material is mainly used for building walls, roofs, tunnels, highways, refuse landfills and the like, can be curled into a roll-shaped flexible building material product for resisting external rainwater and underground water leakage, is used as a leakage-free connection between an engineering foundation and a building, is a waterproof first barrier of the whole engineering, and plays a vital role in the whole engineering. The existing waterproof roll is poor in anti-stretching capacity under the influence of the structure of the existing waterproof roll, after the waterproof roll is constructed, a protective layer is usually required to be applied to prevent the waterproof roll from being damaged by subsequent construction after the waterproof layer is constructed, so that the waterproof quality is influenced, after the waterproof roll is laid, the internal stress is increased due to material shrinkage, the roll is easy to crack to cause leakage, and meanwhile, the existing waterproof roll is not enough in anti-stretching capacity, so that the product is easy to damage, and the quality and the service life of the product are influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a waterproofing membrane with stronger tensile strength, water-proof effects is good, long service life.
To achieve the above object, the utility model provides a: a waterproof coiled material comprises a polyurethane base cloth layer, wherein a stainless steel fiber net is arranged in the polyurethane base cloth layer, and an upper bonding layer, an isolation layer, a glass fiber mesh cloth layer, an upper waterproof layer and a film coating surface layer are sequentially arranged on the upper side of the polyurethane base cloth layer from bottom to top; the lower side of the polyurethane base fabric layer is sequentially provided with a lower bonding layer, a composite geotextile layer, a CCB (cellulose-binding-.
Preferably, the stainless steel fiber mesh is made of lead-plated, zinc-plated or tin-plated metal.
Preferably, the isolation protection layer is made of polyethylene terephthalate or polyethylene silicone oil.
Preferably, the upper waterproof layer is a chlorinated polyethylene-rubber blended waterproof layer.
Preferably, the surface layer of the covering film is a polyethylene film or a polyester film.
The utility model has the advantages that:
1. because the stainless steel fiber net is arranged in the polyurethane base cloth layer, the tensile resistance of the polyurethane base cloth layer is enhanced, and the tensile resistance of the coiled material waterproof layer is further enhanced;
2. the upper side of the polyurethane base cloth layer is sequentially provided with the upper bonding layer, the isolation layer, the glass fiber gridding cloth layer and the upper waterproof layer from bottom to top, so that the tensile strength of the waterproof roll is further improved, particularly, the waterproof layer is not easy to crack due to the influence of the cushion layer precipitation in underground construction, the polyurethane base cloth layer is well protected, and the tensile strength and the waterproof performance of the waterproof roll are effectively improved;
3. the composite geotextile layer and the CCB reaction bonding strong glue layer composite geotextile layer are bonded on the lower side of the polyurethane base fabric layer, so that the seepage-proofing and corrosion-resisting capabilities of the coiled material are further improved, and the phenomena of hardening, wrinkling and even fracture of the waterproof coiled material are avoided, so that the service life of the waterproof coiled material is prolonged; the CCB reaction glues powerful glue film, and the surface that CCB reaction glues powerful glue film has active group, and this active group can take place chemical reaction with cement gel, so can realize this waterproofing membrane and the high-strength high sealed bonding effect of cement base layer, and the bonding effect does not descend along with the extension of time, and the bonding is firm, the construction of being convenient for.
