Abstract
The utility model relates to a novel waterproof vapor-penetrating film which comprises two layers of structures, wherein the upper layer is a polyester spun-bonded non-woven fabric, and the lower layer is a macromolecule moisture permeable film. The polyester spun-bonded non-woven fabric and the macromolecule moisture permeable film are compounded into a laminar structure through a PU (polyurethane) glue or hot melt adhesive. By adopting the technology, the water resistance, vapor permeability, ageing resistance and strength of the waterproof vapor-penetrating film are enhanced, and the manufacturing cost is lower.
Description
Technical field
The utility model relates to a kind of building water-proof energy-saving material, particularly the saturating steam film of a kind of new waterproof.
Background technology
Waterproof ventilated membrane: under the state of steam, particle water is very tiny, according to the principle of capillary moving, can be penetrated into smoothly capillary to opposite side, thereby vapour phenomenon occurs.When steam condensation becomes after the globule, it is large that particle becomes, and due to the capillary effect of the globule (between hydrone mutual " pull and contend with "), hydrone just can not depart from smoothly the globule and be penetrated into opposite side, the infiltration that has namely prevented water occurs, and makes steam film have the function of waterproof.
Chinese patent CN201437622U discloses a kind of water-proof air-permeable film of composite gridding reinforcement, the four-layer structure water-proof air-permeable film being composited by PUR lamination by nonwoven layer, macromolecule membrane layer, grid reinforcing rib layer, nonwoven layer successively from top to bottom, the waterproof that this scheme realizes and, water proofing property and the steam permeability of steam film are better thoroughly, its intensity is being improved aspect two in length and breadth.But, adopt this scheme, there is certain defect in the ageing resistace of water-proof air-permeable film and intensity.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide the saturating steam film of a kind of new waterproof, make to increase in water proofing property, steam permeability, ageing resistance and the intensity of water-proof air-permeable film, and more cheap on cost.
In order to solve the problems of the technologies described above, the utility model provides a kind of new waterproof saturating steam film, and water-proof air-permeable film comprises two-layer structure, and upper strata is terylene spun-bonded nonwoven, and lower floor is macromolecule moisture permeable membrane.
Further, described water-proof air-permeable film is three-decker, is respectively terylene spun-bonded nonwoven, macromolecule moisture permeable membrane and terylene spun-bonded nonwoven from top to bottom.
Further, in described water-proof air-permeable film, terylene spun-bonded nonwoven and macromolecule moisture permeable membrane are complex as layer structure by PU glue or PUR.
Further, described macromolecule moisture permeable membrane is TPU, or PU, or PTFE, or PE moisture permeable membrane.
Further, described terylene spun-bonded nonwoven is by the long fine nonwoven of PET, fabric cloth, or glass fibre non-woven substitutes.
Adopt technique scheme, the technique effect of generation is:
The intensity of terylene spun-bonded nonwoven is high, resistance to elevated temperatures good (can in 150 ℃ of environment, use for a long time), ageing-resistant, uvioresistant, percentage elongation are high, stability and good permeability, corrosion-resistant, sound insulation, mothproof, nontoxic.And water-proof air-permeable film is when strengthening building air-tightness, watertightness, the permeability performance that it is unique, can make inside configuration steam discharge rapidly, avoids structure to multiply mould, protection property value, and perfection has solved protection against the tide and people's health in residential environment; Steam is discharged rapidly, and protection enclosed structure thermal property, is a kind of new energy-saving material of health environment-friendly.
Accompanying drawing explanation
Fig. 1 is two layers of composite construction schematic diagram of the present utility model.
Fig. 2 is three-layer composite structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
Embodiment 1: as shown in Figure 1, the utility model comprises two-layer structure, and upper strata is terylene spun-bonded nonwoven 1, and lower floor is macromolecule moisture permeable membrane 2.
Embodiment 2: as shown in Figure 2, the utility model, on the basis of embodiment 1, can be combined into three-decker, is respectively terylene spun-bonded nonwoven 1, macromolecule moisture permeable membrane 2 and terylene spun-bonded nonwoven 3 from top to bottom.
In above two embodiment, terylene spun-bonded nonwoven and macromolecule moisture permeable membrane are bonded together by PU glue or PUR lamination composite algorithm.Meanwhile, the terylene spun-bonded nonwoven that the utility model has can be substituted by other materials, and for example PET grows fine nonwoven, fabric cloth, or glass fibre non-woven, and macromolecule moisture permeable membrane is TPU, or PU, or PTFE, or PE moisture permeable membrane.
