Abstract
The utility model relates to a compound venting film for building. The compound venting film for building is composed of an upper layer, a middle layer and a lower layer which are compounded in turn from top to bottom, wherein the upper layer and the lower layer are both non-woven fabric layers; the middle layer is a PE (Poly Ethylene) venting film layer; and the upper layer, the middle layer and the lower layer are glued in a holt-melt gluing dot mode or net mode. The compound venting film is difficult to snap and is high in tensile strength; when the compound venting film is adopted between a building waterproof layer and a road surface structural layer, an embedding method is optimally adopted for paving the compound venting film; the fibers on the surfaces of the upper and lower non-woven fabric layers are firmly combined with building materials, such as cement plaster and pitch; and the PE layer is venting and waterproof and is excellent in seepage-proofing property.
Description
Technical field
The utility model relates to a kind of structure material, in particular a kind of composite ventilating film for building.
Background technology
In the house ventilating water proof layer in builing industry, often use breathable films, be used for improving life-span and the heat-proof quality of building own at the heat-barrier material of masonry the inside, in addition in the building of some wooden structures also used as the moistureproof and waterproof material, inside and outside mainly it being layered on ceiling the inside or the heat-barrier material of wall the inside being rolled in, the advanced countries such as Europe, Japan have been widely used in.
Summary of the invention
The purpose of this utility model be to provide a kind of can be efficiently and cement mortar, pitch (waiting constructional materials) combination, waterproof and breathable composite ventilating film for building simultaneously.
For achieving the above object, technical solution of the present utility model is: a kind of composite ventilating film for building, comprise the upper strata, middle level, the lower floor that are composited successively from top to bottom, and described the upper and lower are nonwoven layer, and the middle level is the ventilative rete of PE.
Described upper strata, middle level and lower floor's employing PUR point type or net like are bonding.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: composite ventilating film of the present utility model is difficult for breaking, tensile strength is high, it is applied between buildings waterproof, the road surface structure layer, preferably adopt implantation to lay, up and down the fiber on nonwoven layer surface can with cement mortar, pitch (waiting constructional materials) strong bonded, the polythene PE layer can air permeable waterproof, barrier performance is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
(indicate among the figure: 1, upper strata; 2, middle level; 3, lower floor).
The specific embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of composite ventilating film for building of the present utility model, comprise the upper strata 1, middle level 2, the lower floor 3 that adopt successively from top to bottom PUR point type or net like to be bonded, upper strata 1 and lower floor 3 are nonwoven layer, middle level 2 is the ventilative rete of PE, up and down the fiber on nonwoven layer surface can with cement mortar, pitch (waiting constructional materials) strong bonded, the ventilative rete of PE can air permeable waterproof, barrier performance is good.
Above-described, only be a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
