The invention discloses a kind of sandwich construction pipeline rehabilitation flat hose, flat hose includes five layers of mechanism, five layers of mechanism include the adhesive layer between adhesive layer and intermediate layer and outer layer between intermediate layer, inner liner, outer layer, intermediate layer and inner liner, intermediate layer is network structure, and inner liner is PVDF layers.The flat hose of the present invention, not only significantly reduces cost, and taken into account excellent oil resistant, high temperature resistant, antiseptic property.
Description
Technical field
The present invention relates to the technical field of flat hose, and in particular to a kind of sandwich construction pipeline rehabilitation flat hose.
Background technology
Existing flat hose is typically double-layer structure or three-decker：Double-layer structure is high polymer material liner, outer layer
Fiber braiding layer；Three-decker is：Middle organization level and inside and outside two layers, and inside and outside one-shot forming co-extrusion, interior exterior materials are generally
Same material, or extruded using material polarity and two kinds of same or like different materials of compatibility are simultaneously inside and outside, material
Polarity and solubility parameter differ larger material co-extrusion and can not be bonded together.In order to ensure flat hose oil resistant, high temperature resistant,
Corrosion-resistant performance, the flat hose of sandwich construction often uses PVDF as raw material in the prior art, but the cost of material is higher,
It is difficult to promote, market competitiveness is poor.
The content of the invention
Used it is an object of the invention to the problem above for overcoming prior art to exist there is provided a kind of sandwich construction pipeline rehabilitation
Flat hose, not only significantly reduces cost, and taken into account excellent oil resistant, high temperature resistant, antiseptic property.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：
A kind of sandwich construction pipeline rehabilitation flat hose is provided, the flat hose includes five layers of mechanism, described five layers
Mechanism includes the adhesive layer and the intermediate layer and institute between intermediate layer, inner liner, outer layer, the intermediate layer and the inner liner
The adhesive layer between outer layer is stated, the intermediate layer is network structure, and the inner liner is PVDF layers.
Preferably, the thickness of the liner is 0.2-2.5mm.
Preferably, the outer layer is PE layers, described PE layers thickness is 0.5-3.0mm.
Preferably, the intermediate layer is fiber braid, the fiber is in polyester fiber, nylon fiber, aramid fiber
One kind, the lines in the intermediate layer is plain weave or twill.
Preferably, the gluing layer material be TPO PUR, the TPO PUR be specially EVA,
One or more in EAA, EMA, the thickness of the adhesive layer is 0.1-2.0mm.
Preferably, the adhesive layer is thermoplastic polyurethane TPU, the thickness of the adhesive layer is 0.05-3.0mm.
Using above structure and material, a kind of sandwich construction pipeline rehabilitation flat hose of the invention and prior art phase
Than with advantages below：
1. flat hose of the invention has excellent oil resistant, high temperature resistant, antiseptic property, and caking property between layers is more
It is good；
2. while excellent oil resistant, high temperature resistant, antiseptic property is ensured, the cost of final products, PVDF are substantially reduced
Price is high, and the present invention replaces part PVDF using thermoplastic polyurethane, and does not influence the chemistry and mechanical property of final products；
3. the present invention is solved between layers because viscous between the material that polarity is different, solubility parameter difference is larger
Knot property, the stability of product is stronger.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
The embodiment of the present invention is shown in detail by following examples and its accompanying drawing.
Brief description of the drawings
Technical scheme in technology in order to illustrate the embodiments of the present invention more clearly, in being described below to embodiment technology
The required accompanying drawing used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present invention
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is the structural representation of the sandwich construction pipeline rehabilitation flat hose of the present invention；
Wherein, 1. intermediate layer, 2. inner liners, 3. outer layers, 4. adhesive layers, 5. adhesive layers.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The present invention provides a kind of sandwich construction pipeline rehabilitation flat hose, and flat hose includes five layers of mechanism, five layers of machine
Structure is included between adhesive layer 4 and intermediate layer 1 and outer layer 3 between intermediate layer 1, inner liner 2, outer layer 3, intermediate layer 1 and inner liner 2
Adhesive layer 5, intermediate layer 1 be network structure, inner liner 2 be PVDF layers.
The thickness of the liner is 0.2-2.5mm, and the thickness of further preferred liner is 0.2-1.0mm, is not being influenceed most
On the premise of finished product performance, inner liner PVDF usage amount is reduced as far as possible, and flat hose product cost is reduced as far as possible.
The outer layer is PE layers, and described PE layers thickness is 0.5-3.0mm, and further preferred E layers thickness is 0.5-
2.0mm.By PE layers, it is set to ensure the crocking resistance of flat hose when using its pipeline rehabilitation.
The intermediate layer is fiber braid, and the fiber is one kind in polyester fiber, nylon fiber, aramid fiber, institute
The lines for stating intermediate layer is plain weave or twill, by the design in this kind of intermediate layer, increase intermediate layer and adhesive layer and adhesive layer it
Between contact, fastness is stronger.
The gluing layer material is TPO PUR, during the TPO PUR is specially EVA, EAA, EMA
One or more, the thickness of the adhesive layer is 0.1-2.0mm.
The adhesive layer is thermoplastic polyurethane TPU, and the thickness of the adhesive layer is 0.05-3.0mm, further preferably viscous
The thickness for closing layer is 0.05-1.0mm.
Adhesive layer in the present invention and adhesive layer are set, solve well because between intermediate layer and liner, outer layer because
For polarity difference and solubility parameter difference it is larger cause the problem of its caking property is poor, caking property between layers
It is stronger.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
