Abstract
The utility model relates to a structure-improved water pipe, which is characterized in that an interface layer is additionally arranged in a double-layer structure of a drinking water pipe, interface layer adhesive agent which is hot-melt adhesive of ethene-vinyl acetate polymer (EVA), emulsion of polyvinyl acetate (PAVc), and polymer of vinyl alcohol (EVOH), and polyvinyl alcohol shrank into aldehyde (PVB) is adopted by the interface layer. An inner and an outer layer interfaces are provided with a netted and multiple axial patterns or rough surfaces which are vertically and horizontally interleaved and is provided with unevenness grooves, and the inner layer and the outer layer are mutually attached together through coating of the adhesive agent on the multiple axial patterns and rough surfaces of the inner and the outer layer interfaces. The double effect of enhancement of tensile strength and the enhancement pulling strength can be realized.
Description
The utility model relates to a kind of double layer drinking-water pipe, particularly a kind of water pipe of architecture advances.
General known drinking-water pipe is for meeting flat partially rate, tensile strength, water pressure resistance, vacuum, the heavy metal stripping, dipping acid-alkali-corrosive-resisting degree, the convenience that construction is laid, various and the changeable pliability of corresponding geology, the smooth and easy every basic demand such as flow of level and smooth fluid in the water hammer of normal throw and the pipe, mostly take interior outer double-layer structure (as shown in Figure 1), that is be inner layer material 10 with PE (polyethylene), PVC (rigid polyvinyl chloride) makes for cladding material 20 and forms, because polyethylene and PVC have the difference of its material structure, and it is compatible bad, its structural strength is the consideration of opening property of nonreactive both, also do not take the requirement of pull resistance into account, thereby be the creation (as shown in Figure 2) that Taiwan patent announcement No. 138593 and No. 164676 " potable water dedicated pipe " is arranged, this creation is in interior, outer tube 10, the 20 outside dentate stripes 30 of going up annular spread wear mutually to make it to closely cooperate and form, because the machinery that its what is called closely cooperates to the single axial striped clamps together the mode of wearing, though there is it to improve the function of tensile breaking strength, but its internal and external layer material is compatible bad, be easy to generate and peel off, and its internal stress can't disappear, can produce original shortcomings such as be full of cracks and tensile strength thereof is nonconforming and all still exist, all this is known double layer drinking-water pipe and Taiwan patent announcement " potable water dedicated pipe " and does not have practical value and have much room for improvement.
The purpose of this utility model is the water pipe that a kind of architecture advances will be provided, it can not only improve aforementioned known inside and outside double layer drinking-water pipe and structurally fail to take into account simultaneously tensile breaking strength and tensile strength and peel off easily, can produce every shortcomings such as be full of cracks, and be coated on inside and outside bed boundary multiaxis by the interface layer solid and to lines or hair side internal and external layer bondd mutually, to reach the dual function of use that not only can strengthen tensile breaking strength but also can strengthen tensile strength.
The purpose of this utility model is achieved in that
A kind of water pipe of architecture advances, this water pipe mainly is to be that internal layer and rigid polyvinyl chloride PVC material are constituted by outer with the polythene PE material, it is characterized in that: be equipped with interface layer between its internal layer and the skin, this interface layer is the adhesion agent layer that the internal and external layer material is bondd.
Adhesive interface of this inside and outside layer is provided with multiaxis that longitude and latitude interweaves in length and breadth to concavo-convex ditch slot texture or hair side.
This interface layer is to be dipped in solid in advance with silvalin bundle, felt band, cloth sheet or continuous numb suitable material to be entwined.
The interface layer that adds in the utility model drinking-water pipe double layer construction is that to adopt ethene-vinyl acetate co-polymer (EVA) hot melt adhesive, polyvinyl acetate (PVAc) latex, vinyl alcohol copolymer compound (EVOH), polyvinylbutyral (PVB) be the interface layer solid, to reach the purpose that not only can strengthen tensile breaking strength but also can strengthen the dual use effect of tensile strength.
The utility model not only can be strengthened the inside and outside layer of drinking-water pipe bond effect, and has the double effects of strengthening tensile breaking strength and tensile strength.
Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.
Description of drawings:
Fig. 1 is the double layer construction schematic representation of known drinking-water pipe;
Fig. 2 is the double layer construction schematic representation of No. 138593 and No. 164676 case of Taiwan patent announcement;
Fig. 3 is the utility model basic structure schematic representation;
Fig. 4 is the utility model one example structure schematic representation;
Fig. 5 is another example structure schematic representation of the utility model.
As shown in Figure 3, the utility model mainly is that to add one inside and outside drinking-water pipe in double- deck 10,20 structures be interface layer 40 with the solid.
The double layer construction of drinking-water pipe is to be internal layer 10 with polyethylene (PE) material, serves as outer 20 with rigid polyvinyl chloride (PVC) material.Internal layer 10 materials (PE) have good chemical characteristics and avirulent and stability, its on embodiment upgrading in addition, in known bridge formation mode, improve its molecule framework and form the cubic element reticular structure, and outer 20 materials (PVC) have weatherability and other good physical propertys, it also must add elastomer or ooze on embodiment joins fiber and upgrading in addition, to strengthen its tensile strength, compressive strength.
The internal layer 10 of the utility model drinking-water pipe and outer 20 interface layers that add 40 are that to adopt ethene one vinyl acetate copolymer (EVA) hot melt adhesive, polyvinyl acetate (PVAc) latex, vinyl alcohol copolymer compound (EVOH), polyvinylbutyral (PVB) be boundary's stratification 40 solids.
Aforementioned drinking-water pipe internal layer 10 materials (PE) and outer 20 materials (PVC) are because of having known structural difference and compatible bad situation, 40 (as shown in Figure 3) of the outer within it interlayer construction of the utility model interface layer, utilize the interface layer solid to be bondd, can strengthen its tensile breaking strength and tensile strength.
The utility model is long-pending for improving interface layer 40 bonding surfaces, on embodiment (as shown in Figure 4) in its adhesive interface be provided with multiaxis that longitude and latitude interweaves in length and breadth to the lines or the hair side 50 of concavo-convex groove, it not only can reinforced cementitious effect, also can strengthen rerum natura simultaneously.
Aforementioned interface layer 40 (as shown in Figure 5) on another embodiment also is able to silvalin bundle, felt band, cloth sheet or continuous numb suitable material 60 and is dipped in aforementioned interface layer solid in advance and is wound between the internal and external layer 10,20.
In sum, the utility model is to add interface layer 40 between internal layer 10 materials (PE) that constitute drinking-water pipe and outer 20 materials (PVC), this interface layer 40 be the adhesive surface with internal and external layer be provided with multiaxis that longitude and latitude interweaves in length and breadth to the lines of concavo-convex groove or hair side solid in addition, or with the silvalin bundle, the felt band, cloth sheet or continuous numb suitable material are dipped in solid in advance and are entwined, it not only can reinforced cementitious effect and strengthens its rerum natura, and has the double effects of strengthening tensile breaking strength and tensile strength, it is configured to not seen before, have novelty and advance, prodigiosin is promoted function of use, is the creation of closing in the utility model patent important document.
