The thermoplastic resin winding pipe and its preparation process 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：It is described including inner layer resin and outermost resin
Uniform winding fiberglass band among inner layer resin and outermost resin, the fiberglass band is " Ω " type, its two bottom sides has plane
Extension, has binding resin among the extension of the adjacent two fiberglass band.
The extension is conducive to increase the rigidity of winding pipe to be integrally formed with fiberglass band.
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, prepared using pultrude process
State " Ω " type fiberglass band；
（2）Prepare fiberglass band/thermoplastic resin composite band：With step（1）The fiberglass band and thermoplastic resin of preparation be
Raw material, using extrusion mechanism for fiberglass/thermoplastic resin composite band；
（3）Shaping：By step（2）The fiberglass of preparation/thermoplastic resin composite band is wrapped on the pipe mold of heating and uses
Plastic welding practices are integrally welded by the seam crossing between band and band, and be cooled and shaped；
（4）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, easy to subsequently be wound in pipe
Material.
The step（3）In forming process, extruded using seam crossing of the extruder in fiberglass/thermoplastic resin composite band
A small amount of thermoplastic resin is as binding resin（4）.
Step（2）、（3）The thermoplastic resin is polyethylene, in 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
Without binding agent 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 reduces 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.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Attached drawing 1 is a kind of structure 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.
Embodiment
As shown in Figure 1, the thermoplastic resin winding pipe of the glass steel strip reinforced, including inner layer resin 1 and outermost resin
2,2 middle uniform winding " Ω " the type fiberglass band 3 of 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, prepared using pultrude process
State " Ω " type fiberglass band；
（2）Prepare fiberglass band/thermoplastic resin composite band：With step（1）The fiberglass band and thermoplastic resin of preparation be
Raw material, using extrusion mechanism for fiberglass/thermoplastic resin composite band；
（3）Shaping：By step（2）The fiberglass of preparation/thermoplastic resin composite band is wrapped on the pipe mold of heating and uses
Plastic welding practices are integrally welded by the seam crossing between band and band, while use a small amount of fusing of extruder extrusion in seam crossing
Thermoplastic resin as binding resin 4, and be cooled and shaped；
（4）Intercepted by tubing after cooling and mold releasability, and according to required length.
The thermoplastic resin is at least one of polyethylene, polypropylene, polybutene, polyvinyl chloride, haloflex.
Step（1）In fiber at least one of for polyester fiber, glass fibre or carbon fiber；Thermosetting resin is not
