Abstract
The utility model discloses a waterproof breathable film of a composite grid reinforcing rib. The waterproof breathable film is laminated and composited by a non-woven fabric layer, a polymer film layer, a grid reinforcing rib layer and a non-woven fabric layer through hot melt adhesive sequentially from top to bottom. The waterproof breathable film has the advantages that the waterproofness and the breathability are good, the strength is improved vertically and horizontally, and the actual construction requirements of the modern construction are completely met.
Description
Technical field
The utility model relates to a kind of building water-proof energy-saving material, is specifically related to a kind of water-proof air-permeable film of composite gridding reinforcing rib.
Background technology
The structural concept that is made of roof tile, gauze wire cloth pea gravel concreten, thermal insulation layer, self-adhesive coiled material or coating waterproofing, cast-in-situ steel reinforced concrete roofing is being adopted in domestic construction design at present basically aspect the pitched roof structure, there is following main hidden danger in this scheme: 1, winter, indoor/outdoor temperature-difference made the pea gravel concreten bottom form condensation, destroyed the thermal property of insulation layer.2, pea gravel concreten is easy to crack, and fixedly the steel nail of batten destruction waterproofing course causes rainwater to scurry into hole for nailing, causes roof leakage.3, the asphalt felt and the extension toughness of filming are relatively poor, and the variation of structure makes the material cracking easily, causes roof leakage.4, self-adhesive coiled material or film because of seal, moisture is closed in the roof structure, and indoor wet steam can not distribute, and roof structure is easy to multiply mould, and influence is lived healthy.Wooden construction or metal Roof easily rot too early.
The water-proof air-permeable film has solved the problems referred to above well, obtains the great attention of the Ministry of Construction, and China Inst of Architectural Standard Design has gone out special atlas: national building standard design atlas 07CJ09 " water-proof air-permeable membrane building structure ".At present the water-proof air-permeable film that uses adopts nonwoven+macromolecule moisture-permeable film+non-woven fabric compounded forming more, and steam permeability is good, but the strength of materials is lower, and is damaged easily and cause product itself to lose water-proof function in the construction, can't satisfy construction requirement, therefore is difficult to promote.
Summary of the invention
Task of the present utility model is at the problems referred to above, and a kind of water-proof air-permeable film that increases the composite gridding reinforcing rib of the mechanical strength of water-proof air-permeable film own is provided, and water proofing property, steam permeability are good, makes it can satisfy the purpose that practice of construction requires well.
The water-proof air-permeable film of the composite gridding reinforcing rib that the utility model provides, be on the water-proof air-permeable film basis that forms by nonwoven, macromolecule moisture permeable membrane, nonwoven three layer construction of using at present, compound again one deck grid reinforcing rib forms, and promptly is made of nonwoven layer, macromolecule membrane layer, grid reinforcing rib layer, nonwoven layer successively from top to bottom.
The water-proof air-permeable film of the composite gridding reinforcing rib that the utility model provides is a kind of four-layer structure water-proof air-permeable film that nonwoven layer, macromolecule membrane layer, grid reinforcing rib layer, nonwoven layer are composited by the PUR lamination.
Described grid reinforcing rib is by PP, or PE, or glass fiber material through weft-knitted fabric.
The water-proof air-permeable film of the composite gridding reinforcing rib that the utility model is composited by the PUR lamination by nonwoven+macromolecule moisture-permeable film+grid reinforcing rib+nonwoven is a kind of building water-proof energy-saving material, and its characteristics are as follows:
1) waterproof is more secure: the water-proof air-permeable film is layed on the counter batten, and is sagging naturally between two counter battens, and follows closely the hole at lofty perch, and rainwater is difficult for scurrying into hole for nailing, and waterproof is more secure; 2) energy efficient: the space enclosing structure internal steam is discharged, protection space enclosing structure thermal property, energy efficient rapidly; 3) away from mould: the building structure internal steam is discharged rapidly, avoids mould to multiply, and indoor air environment is in the general level of the health, and the human settlement is more comfortable; 4) the protection property is worth: the building structure internal steam is discharged rapidly and is kept dry, and improves durability of structures, and the protection property is worth; 5) reduce cost, raising safety factor: the water-proof air-permeable film replaces traditional waterproof coiled material and has also replaced the pea gravel concreten topping on the insulation layer, reduces construction engineering cost and also improves safety factor; 6) the water-proof air-permeable film that will be composited by the PUR lamination, combination process is simple, compound grid reinforcing rib all is improved the two aspect intensity in length and breadth of product, after tested, the hot strength of the utility model product is laterally more than or equal to 420N/50mm, vertically, by the use of some projects, satisfy the practice of construction requirement fully more than or equal to 420N/50mm; 7) grid reinforcing rib is can be well compound with nonwoven, film, and complex technique is simple, and cost of production is low.
Description of drawings
Fig. 1 is the cross-sectional view (sectional structure charts at amputation two ends) of a kind of example structure of the present utility model, 1. nonwoven layer, 2. macromolecule membrane layers, 3. grid reinforcing rib layer, 4. nonwoven layer among the figure
The specific embodiment
Be further described below in conjunction with embodiment and accompanying drawing thereof.
Referring to embodiment shown in Figure 1
A kind of water-proof air-permeable film with composite gridding reinforcing rib, its structure comprise that upper surface nonwoven layer (1), macromolecule membrane layer (2), grid reinforcing rib layer (3) and soffit nonwoven layer (4) constitute.PUR lamination composite algorithm is adopted in the production of the water-proof air-permeable film of this composite gridding reinforcing rib.
Not fabric of polyester, fiber, polypropylene or polyethylene can be adopted in surface course nonwoven of the present utility model (1) and (4); Macromolecule membrane (2) is good, the good steam permeability of water resistance not only, and the space enclosing structure internal steam is discharged rapidly, protection thermal property, energy efficient; Can adopt PE or TPU material.
Grid reinforcing rib layer of the present utility model (3) is by the PP fibrous material, or the PE fibrous material, or glass fiber material through weft-knitted fabric; The water-proof air-permeable film that is composited by the PUR lamination, compound grid reinforcing rib all is improved the two aspect intensity in length and breadth of product, with the strength ratio of existing product: existing product hot strength laterally is generally 200N/50mm, vertically is generally 180N/50mm; Hot strength of the present utility model is laterally more than or equal to 420N/50mm, vertically more than or equal to 420N/50mm, and the use by some projects, satisfy the practice of construction requirement fully.
