Abstract
The utility model discloses a water-proof coil with adhesive film between surface layer and waterproof layer, which is provided with upper and lower non-woven fabric surface layers, an in-between waterproof layer made of polyethylene film, and adhesive films made of ethane-vinyl acetate copolymer arranged between the non-woven fabric surface layers and the waterproof layer made of polyethylene film. Compared with the prior water-proof coil of the same kind, the utility model has the advantages of high peeling strength of seam binding, good impermeability, and easy construction.
Description
Technical field
The utility model relates to construction engineering waterproof material, is the waterproof roll that is provided with bonding film between a kind of surface course and the waterproofing course.
Background technology
The existing waterproof roll that is used for construction work generally is waterproofing course in the middle of being with the polyethylene film, is that surface course constitutes at the upper and lower surface composite spunbonding process polypropylene filament yarn nonwoven of waterproofing course.When such waterproof roll is used,, be difficult to the strong bonded of realization and bonded adhesives in construction work, thereby the bonding peel strength and the anti-water permeability that are directed at seam can reduce greatly because the surperficial bonding peel strength of polyethylene film is very little.
The utility model content
The purpose of this utility model is at the problems referred to above, and the waterproof roll that is provided with bonding film between a kind of seam adhesive strength height, the reliable surface course of water resistance and the waterproofing course is provided.
The technical solution of the utility model is: the waterproof roll that is provided with bonding film between a kind of surface course and the waterproofing course, it has nonwoven upper and lower surface layer and places middle polyethylene film waterproofing course, is provided with the bonding film of being made by ethylene-vinyl acetate copolymer between upper surface layer and polyethylene film waterproofing course.
The technical solution of the utility model also comprises: be provided with the bonding film of being made by ethylene-vinyl acetate copolymer between nonwoven undersurface layer and polyethylene film waterproofing course.
The utility model is compared with existing similar waterproof roll, has following advantage:
1, adhesive property is good.Because ethylene-vinyl acetate copolymer is the polar molecule material, but has good viscosity, thereby the peel strength of coiled material itself and the peel strength of adhesive joins all are greatly improved, its bonding peel strength is increased to more than the 15N/cm by original 4N/cm.In addition, because this waterproof roll does not need to carry out surfacing, the seam easy construction before bonding.
2, impermeability is good.Because bonding film is set between upper surface nonwoven and waterproofing course, the bonding adhesive during the seam construction can pass through the direct and ethylene-vinyl acetate copolymer film realization strong bond of nonwoven, thereby the performance of watertightness of waterproof roll seam is improved greatly.
3, shock resistance is good.The ethylene-vinyl acetate copolymer material itself has the good characteristics of resilient flexible, therefore is applied in the impact strength that can improve the waterproof roll seam in the waterproof roll.
Description of drawings
Accompanying drawing is the sectional drawing that is provided with the waterproof roll of bonding film between this surface course and the waterproofing course.
The specific embodiment
The utility model is described in further detail for embodiment in conjunction with the accompanying drawings:
As accompanying drawing 1, this waterproof roll has nonwoven upper surface layer 1 and nonwoven undersurface layer 2 and places middle polyethylene film waterproofing course 3, its nonwoven surface layer can adopt polypropylene filament yarn fabric hot rolled nonwoven fabrics or Dacron short staple needle punching non-woven cloth in the specific implementation, and waterproofing course can adopt the low density polyethylene films that adds auxiliary agent.Be provided with the bonding film of being made by ethylene-vinyl acetate copolymer 4 between upper surface layer 1 and polyethylene film waterproofing course 3, the thickness of its bonding film 4 is chosen as about 0.02mm.
In practice of construction, the seam of waterproof roll is generally carried out at upper surface, consider the special circumstances that have adhesive strength to require to soffit in the construction, provide as accompanying drawing 2, the bonding film of being made by ethylene-vinyl acetate copolymer 5 can be set between nonwoven undersurface layer 2 and polyethylene film waterproofing course 3.
When this waterproof roll is produced, after making above-mentioned layer of cloth and rete enter heating cabinet jointly to be heated to bonding film and waterproof film fusion, be combined into one, make this waterproof roll through hot pressing.
Claims (2)
1, is provided with the waterproof roll of bonding film between a kind of surface course and the waterproofing course, have nonwoven upper surface layer (1) and nonwoven undersurface layer (2) and place middle polyethylene film waterproofing course (3), it is characterized in that: between upper surface layer (1) and polyethylene film waterproofing course (3), be provided with the bonding film of making by ethylene-vinyl acetate copolymer (4).
2, by the waterproof roll that is provided with bonding film between described surface course of claim 1 and the waterproofing course, it is characterized in that: between nonwoven undersurface layer (2) and polyethylene film waterproofing course (3), be provided with the bonding film of making by ethylene-vinyl acetate copolymer (5).
