The resin materials such as ethylene (HDPE), polyvinyl chloride (PVC) since itself is excellent melt welding performance not only and ensure that product at
Type technique and product quality, and a variety of reliable fashions are provided for construction connection, such as electric heating fusion welding, it is heat-shrinked connection etc.
Deng, while this is also the major reason that leakage scenarios seldom occur, exactly because also this reason, this tubing just has
The unique environment-friendly function that other tubing do not have, to be obtained extensively in fields such as drainage pipeline, conveyance conduit, wire and cables
Using.
The winding pipe of the prior art generallys use reinforcing fiber as reinforcing material, such as glass fiber impregnated cloth is wound
Enhanced in tube surfaces, however, the usual thermal insulation property of this winding pipe is insufficient, limits winding pipe answering in HVAC field
With therefore, how providing that a kind of intensity is high, and the winding pipe with excellent thermal insulation property is that this field technology urgently to be resolved is asked
Topic.
[utility model content]
It is high that the purpose of this utility model is to provide a kind of intensity, and the composite winding pipe with excellent thermal insulation property.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of enhanced heat preservation composite winding pipe, including internal layer, sandwich layer and outer layer, wherein internal layer is stainless steel tube, sandwich layer
For high-temperature-resistant epoxy resin glue, outer layer is PVC/TPU composite strip winding layer, and PVC/TPU composite strip is by PVC band and micro- hair
It steeps TPU band to constitute, PVC band is equal with the width of fretting map TPU band, wherein the right side two of the width direction of PVC band
/ mono- region has been consecutively embedded ceramic fibre felt along its length, and the left side two of the width direction of fretting map TPU band is divided
One of region be consecutively embedded glass fibre felt, the left side half region of fretting map TPU band and PVC along its length
The right side half region of band is layered on top of each other overlap joint in the direction of the width, and fretting map TPU band is arranged in PVC band
Inside, PVC/TPU composite strip are the stacked outside for being spirally wound on sandwich layer, each week PVC/TPU composite strip and upper one
Partial layer is stacked with and connects all PVC/TPU composite strips in the direction of the width, make PVC band be not embedded into the part of ceramic fibre felt with
Fretting map TPU band is not embedded into the overlapped bonding in part of glass fibre felt.
Preferably, the PVC band is overlapped by hot pressing and fretting map TPU band.
Preferably, it is overlapped between the PVC band and fretting map TPU band by polyurethane binder.
Preferably, the ceramic fiber blanket band logical overheat pressure is embedded into PVC band.
Preferably, the glass mat band logical overheat pressure is embedded into fretting map TPU band.
The enhanced heat preservation composite winding pipe of the utility model is using PVC/TPU composite strip as winding layer, wherein micro-
The TPU layer that foams has excellent heat insulation effect, while not will lead to that winding layer is blocked up, and the ceramic fiber blanket in PVC band has
Good thermal insulation, while the enhancing for functioning similarly to ribs can be cooperated with the glass fibre felt in fretting map TPU layer
Effect can pass through one moreover, being wound again after overlapping first composition composite strip with fretting map TPU band using PVC band
Secondary winding process is completed at the same time two layers of winding, and does not easily cause pipe thickness caused by the dislocation of two webs is uneven to ask
Topic.
