Abstract
The utility model relates to a high strength compounding film sheet compounded of nonwoven fabric and stretching plastic film sheets. The utility model comprises at least one layer of longitudinally stretching plastic film sheet, at least one layer of latitudinally stretching plastic film sheet and at least one layer of nonwoven fabric. The intensity and performance of the utility model are much higher than common nonwoven compounding film, which can be used as soil engineering film and water-rolling-proof material.
Description
The utility model relates to adhesive-bonded fabric and compound geomembrane and the waterproof roll of plastic film that a kind of engineering is used, particularly be the compound compound diaphragm of high strength of a kind of adhesive-bonded fabric and stretched plastic diaphragm.
Plastic film and coextrusion composite plastic diaphragm are as engineering earth worker film and waterproof roll, in the construction of river dyke, reservoir, tunnel, subway, highway, airport, harbour, garbage bury and all kinds of buildings, obtain to use widely as waterproof, antiseepage processing aspect, become a kind of important geomembrane.But since the plastic film smooth surface in engineering with engineering foundation with cover attachment applying fastness deficiency, therefore compound at some applications use fiber system nonwoven fabric layers and plastic film, or on the plastic film two sides each compound one deck, having improved should geotechnique's journey film strength, bearing capacity and attachment applying fastness improve a lot the earthwork engineering quality.Known geomembrane and compound film sheet are carrying and the requirement of strength that satisfies earthwork engineering, have to that it is enough thick that plastic film is designed to, and its thickness is generally at 0.2-1mm.Because of the adhesive-bonded fabric bearing capacity is very limited, main carrying and intensity all rely on the tensile strength of plastic film.Requirement of strength has been satisfied in such design, but, rigidity thick because of diaphragm is strong, compound film sheet is subjected to certain restriction in the application of earthwork engineering.
In view of above reason, the purpose of this utility model is in order to overcome with deficiency, a kind of intensity height to be provided, the compound diaphragm of high strength that the adhesive-bonded fabric of economical with materials and stretched plastic diaphragm are compound.
The purpose of this utility model is achieved like this:
The compound diaphragm of high strength that the utility model adhesive-bonded fabric and stretched plastic diaphragm are compound comprises at least one deck warp-wise simple tension plastic film, one deck broadwise simple tension plastic film and one deck fiber system adhesive-bonded fabric at least at least.
Adopt the polymer fusion between above-mentioned warp-wise simple tension plastic film and broadwise simple tension plastic film and the fiber system nonwoven fabric layer or bond compound.
Above-mentioned compound film sheet has three layers, and the intermediate layer is that warp-wise simple tension plastic film and broadwise simple tension plastic film are composited, and is compounded with one deck fiber system adhesive-bonded fabric outside the intermediate layer respectively.
The intermediate layer of above-mentioned warp-wise simple tension plastic film and broadwise simple tension plastic film and fiber system nonwoven fabric layer adopt the flexible polymer of heat sealability excellence to be composited respectively.
The utility model has fully been used the crystal type high molecular polymer can produce this characteristic of tensile strength that is several times as much as former film to plastic sheeting under its suitable draft temperature condition after the length of direction simple tension several times, with warp-wise simple tension plastic film and broadwise simple tension plastic film compound be that high strength bidirectional stretch composite membrane replaces above-mentioned plastic film, obtained the plastic film of intensity height, economical with materials, and with fiber system adhesive-bonded fabric compound adhesive-bonded fabric and the compound compound diaphragm of high strength of drawing plastic film of making.The utility model compound film sheet has higher intensity and more performance than general non-woven composite geo-membrane.Can make earthwork engineering film, waterproof roll.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation Fig. 1.
Fig. 2 is the utility model structural representation Fig. 2.
Fig. 3 is the utility model structural representation Fig. 3.
Embodiment 1:
Fig. 1 has provided the utility model embodiment 1 structural representation.Have in the compound diaphragm 1 of the high strength of single face adhesive-bonded fabric that to adopt film thickness be high density polyethylene (HDPE) (or linear polyethylene) the broadwise simple tension diaphragm 2 of 0.03～0.10mm, warp-wise simple tension diaphragm 3, commercially available fabric weight/square metre be the third human relations nonwoven fabric layers 4 of 80～200 grams.Be to be composited by low density polyethylene (LDPE) (also can be linear polyethylene or ethylene-vinyl acetate copolymer) polymeric layer 5,6 fusions (also can bond).The compound diaphragm of present embodiment high strength can be used for geomembrane, building waterproof coil and waterproof roll base cloth.
Embodiment 2:
Fig. 2 has provided the utility model embodiment 2 structural representations.Intermediate layer 8 in the compound diaphragm 7 of the high strength of two-sided adhesive-bonded fabric is that warp-wise simple tension diaphragm 9 and broadwise simple tension diaphragm 10 are composited by polymeric layer 11 fusions (also can bond).Excellent and soft linear polyethylene polymer 12,13 fusions are compounded with nonwoven fabric layer 14,15 by heat sealability respectively on the two sides in intermediate layer.The compound diaphragm of this high strength can and be selected warp-wise simple tension diaphragm 9 for use and the different-thickness and the material of broadwise simple tension film multiple 10 according to the design of the needs of earthwork engineering, and select for use the different grammes per square metre of nonwoven fabric layer 14,15/square metre.This film all is an adhesive-bonded fabric because of the two sides, with the basis and the attachment of engineering the fastness of fitting is preferably arranged all, be the geomembrane that a kind of performance is good, intensity is high, be used for more roadbed such as highway, airport and reservoir, river dyke and tunnel waterproof, anti-ly blend enhancing.
Embodiment 3:
Fig. 3 has provided the utility model embodiment 3 structural representations.Warp-wise simple tension plastic film 17 and broadwise stretched plastic diaphragm 18 in the compound diaphragm 16 of the high strength of single face adhesive-bonded fabric are integral by polymer 19 melt polymerizations.On-woven layer 20 passes through the linear polyethylene polymeric layer 21 of heat sealability excellence with radially simple tension diaphragm 17 is compound.Adopt the linear polymer layer of heat sealability excellence not only to make things convenient for on-woven layer 20, compound with warp-wise simple tension plastic film 17, the construction that also makes things convenient for diaphragm to continue can be adopted fusion to connect diaphragm 22 two compound film sheet fusions are connected.The compound geomembrane of high strength just might be used, otherwise because of the molecular orientation reason of stretched film in engineering, the continuing of diaphragm and diaphragm is difficult to welding and bonding and the compound diaphragm of high strength can't be used in engineering on the stretch orientation face.Polymeric layer 21 also can adopt the polymer-modified of ethylene-vinyl acetate copolymer or low density polyethylene (LDPE).
