Description
Technical field
The present invention relates to tubing technical field, more particularly to a kind of thermoplastic resin winding pipe of glass steel strip reinforced.
Background technology
Currently, the buried draining in the fields such as urban construction, blow-off line mostly use the polyethylene helical wave of steel strip reinforced
Line pipe has many advantages, such as that high rigidity, high intensity, ring stiffness are high.Traditional steel band reinforced polyethylene spiral ripple pipe is by internal layer
Polyethylene, helical steel band and outer layer polyethylene are constituted, and wherein helical steel band serves rigidly, due to helical steel band and polyethylene
It is easy delamination, one layer of binding resin of coating is also needed generally between steel band and polyethylene layer, once steel band is corroded, easily
Safety accident occurs, threatens to people life property safety.
Invention content
A kind of in order to compensate for the shortcomings of the prior art, the present invention provides peel strengths big, uncorruptible fiberglass band
The thermoplastic resin winding pipe of enhancing.
The present invention is achieved through the following technical solutions：
A kind of thermoplastic resin winding pipe of glass steel strip reinforced, it is characterised in that：Including inner layer resin and outermost resin,
Uniform winding fiberglass band among the inner layer resin and outermost resin, the fiberglass band are " Ω " type, and two bottom sides have
There is binding resin in plane development portion among the extension of the adjacent two fiberglass band.
The extension is to be integrally formed with fiberglass band, is conducive to the rigidity for increasing winding pipe.
The inner layer resin and outermost resin are thermoplastic resin.
The binding resin is thermoplastic resin, increases the tight type that connects between fiberglass band, prevent water and air into
Enter.
Further, the preparation process of the thermoplastic resin winding pipe of the glass steel strip reinforced, includes the following steps：
（1）Prepare fiberglass band:Using fiber and thermosetting resin, curing agent, accelerating agent as raw material, using pultrude process system
Standby above-mentioned " Ω " type fiberglass band；
（2）Prepare fiberglass band/thermoplastic resin composite band：With step（1）The fiberglass band and thermoplastic resin of preparation
Fat is raw material, using extrusion mechanism for fiberglass/thermoplastic resin composite band；
（3）Molding：By step（2）The fiberglass of preparation/thermoplastic resin composite band is wrapped on the pipe mold of heating
It is using plastic welding practices that the seam crossing between band and band is integrally welded, and be cooled and shaped；
（4）It is intercepted by tubing after cooling and mold releasability, and according to required length.
Step（1）The thermosetting resin is unsaturated polyester resin, epoxy resin, phenolic resin, melamino-formaldehyde
At least one of resin, furane resins, polybutadiene, organic siliconresin, accelerating agent are fatty amine promoter, acid anhydrides rush
Into at least one of agent, amine type accelerator, tin class accelerating agent.
Step（2）The upper and lower table of the outer surface of fiberglass band and extension in the fiberglass/thermoplastic resin composite band
The uniform coated thermoplastic in face, thermoplastic resin block the lower openings of fiberglass band, convenient for being subsequently wound in pipe
Material.
The step（3）In forming process, the seam crossing using extruder in fiberglass/thermoplastic resin composite band squeezes out
A small amount of thermoplastic resin is as binding resin（4）.
Step（2）,（3）The thermoplastic resin is in polyethylene, polypropylene, polybutene, polyvinyl chloride, haloflex
At least one.
The beneficial effects of the invention are as follows：The present invention glass steel strip reinforced thermoplastic resin winding pipe, fiberglass band with
Binder is not necessarily between thermoplastic resin, bonding force is preferable between each layer, and tubing is sturdy, and ring stiffness is high, and peel strength is higher than steel band
With the peel strength between thermoplastic resin PE, the present invention substitutes steel band using fiberglass band, greatly alleviates the weight of tubing
Amount, while reducing material cost, and seam crossing is bonded using thermoplastic resin, and tubing will not be damaged, will not corrosion, and its
Preparation process is simple, and application prospect is very wide.
Description of the drawings
The present invention will be further described below with reference to the drawings.
Attached drawing 1 is a kind of structural schematic diagram of the thermoplastic resin winding pipe of glass steel strip reinforced of the present invention；
In figure, 1, inner layer resin, 2, outermost resin, 3 fiberglass bands, 4 binding resins, 5 extensions.
Specific implementation mode
As shown in Fig. 1, the thermoplastic resin winding pipe of the glass steel strip reinforced, including inner layer resin 1 and outermost resin
2,2 intermediate uniform winding " Ω " type fiberglass band 3 of the inner layer resin 2 and outermost resin, the two bottom sides of fiberglass band 3 are equipped with
There is binding resin 4 in integrally formed plane development portion 5 among the extension 5 of the adjacent two fiberglass band 3.
The inner layer resin 1, outermost resin 2 and binding resin 4 are thermoplastic resin, and binding resin 4 increases fiberglass
With the tight type connected between 3, prevent water and air from entering.
Further, the preparation process of the thermoplastic resin winding pipe of the glass steel strip reinforced, includes the following steps：
（1）Prepare fiberglass band:Using fiber and thermosetting resin, curing agent, accelerating agent as raw material, using pultrude process system
Standby above-mentioned " Ω " type fiberglass band；
（2）Prepare fiberglass band/thermoplastic resin composite band：With step（1）The fiberglass band and thermoplastic resin of preparation
Fat is raw material, using extrusion mechanism for fiberglass/thermoplastic resin composite band；
（3）Molding：By step（2）The fiberglass of preparation/thermoplastic resin composite band is wrapped on the pipe mold of heating
It is using plastic welding practices that the seam crossing between band and band is integrally welded, while being squeezed out on a small quantity using extruder in seam crossing
