Layer and the second enhancement layer, be provided with the first waterproof layer between the first enhancement layer and the second enhancement layer, the
One enhancement layer outer surface has additional the first wearing layer, and the inner surface of the second enhancement layer has additional successively
Second waterproof layer and the second wearing layer.
First enhancement layer or the second enhancement layer are woven by Polyester Yarns or silk and form.
First waterproof layer and the second waterproof layer by the one in rubber, polyurethane or polrvinyl chloride or
Several make.
First wearing layer and the second wearing layer by the one in rubber, polyurethane or polrvinyl chloride or
Several make.
A kind of processing technique of co-extrusion two-layer compound flexible pipe, step one: use double-deck Co-knit
Technology knits out the first enhancement layer and the second enhancement layer on circular weaving machine；
Step 2: by the common extruding technology of one-shot forming at the first enhancement layer, the second enhancement layer
Outer layer, middle level and internal layer be coated, formed the first wearing layer, the first waterproof layer and
Second waterproof layer；
Step 3: the internal layer at the second waterproof layer is coated with the second wearing layer；
Step 4: semi-finished product step 3 obtained carry out hot vulcanization process after rolling hole again
It is allowed to bond completely, forms finished product.
The invention have the advantage that and use the first enhancement layer and the double-deck of the second enhancement layer to strengthen knot
Structure, can strengthen crushing resistance and the intensity of hookah bodies, the first enhancement layer and the second enhancement layer it
Between be provided with the first waterproof layer and the second enhancement layer internal layer is provided with the second waterproof layer, flexible pipe can be increased
The water proofing property of body and sealing；The first wearing layer it is provided with and outside the first enhancement layer
It is provided with the second wearing layer in two waterproof layers, the inside and outside wearability of hookah bodies can be increased, improve soft
Tube body quality, extends the service life of hookah bodies；
Using above-mentioned production stage, step is easy, and by carrying out heat cure again after rolling hole,
Make the first waterproof layer of being made up of one or more in rubber, polyurethane or polrvinyl chloride and
Second waterproof layer and the first wearing layer and the second wearing layer melt, and mutually bond, and strengthen
The fastness of hookah bodies.
Accompanying drawing explanation
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Wherein: 1, hookah bodies, the 2, first enhancement layer, the 3, second enhancement layer, 4, first
Waterproof layer, the 5, first wearing layer, the 6, second waterproof layer, the 7, second wearing layer.
