Description
Technical field
The utility model belongs to cable duct tube, is specifically related to a kind of MFPT plastic steel composite cable conduit.
Background technique
MFPT plastic steel composite cable conduit, wherein M indicates to be modified, and F indicates that thermoset glass steel composite material, P indicate heat
Thermoplastic plastic, T indicate cable duct tube, are thermosetting plastics and thermoplastic to be complex as an entirety, and the two has complementary advantages,
It is high-strength, heat-resisting, corrosion resistant, fire-retardant, economical and practical.Retrieval it is found that for thermosetting plastics and thermoplastic be complex as one it is whole
A kind of body, " low-resistance wear-resistance burning into sand plastic steel composite cable conduit with salient point " patent of Publication No. CN204651860U, changes
It is to be equipped with salient point in inner tube outer surface and be equipped with quartz sand, quartz sand and hemispherical salient point between glass fiber and inner tube into point
The transition that the frictional force between inner and outer pipes can be increased, but increase the manufacture difficulty of inner tube, and be solidified by quartz sand impregnation
Layer intensity is lower；A kind of " the low-resistance wear-resistance plastic-steel composite cable with intermediate adhesive layer " of Publication No. CN203967702U is special
Benefit, improvement are axially to be coated with one layer of intermediate adhesive layer along inner tube in inner tube outer surface, and intermediate adhesive layer is tight by inner and outer pipes
Close to be combined into an entirety, this method is not easily controlled the amount and uniformity of coated with adhesive, and binder is excessive or mistake
Few binding force that can all reduce between inner and outer pipes, and nonpolarity is presented in the plastic material macromolecular chain of inner tube, is inertia form, mesh
The preceding adhesion problem that inner and outer pipes can be well solved without binder, experiments have shown that plastic inner pipe and glass reinforced plastic outer tube are without place
Reason is directly compound with binder, easily generates layering between the two and falls off, is unable to satisfy and applies man-hour requirement.
Summary of the invention
The utility model mainly solves technical problem present in the above-mentioned prior art, and it is multiple to provide a kind of MFPT plastic-steel
Close cable duct tube.
Above technical problems of the utility model are mainly solved by the following technical scheme: a kind of MFPT plastic-steel
Composite cable conduit, including plastic inner pipe and glass reinforced plastic outer tube are wound with the glass with knot on the outer surface of the plastic inner pipe
Fiber, the outer surface of plastic inner pipe is made the lower half portion of knot be embedded in the appearance of plastic inner pipe by thermal softening when winding glass fibre
In face, glass fibre and knot thereon are impregnated with resin adhesive liquid when coated with glass fibre reinforced plastics outer tube, and glass fibre and knot thereon are also together
Curing molding is a part of glass reinforced plastic outer tube.
Preferably, the diameter tied on the glass fibre is 2-4mm, the spacing of knot is 3-5cm.
Preferably, the glass fibre spiral wrap is on the outer surface of plastic inner pipe, screw pitch 2-4cm.
It is spare after extrusion inner tube and fixed length cutting when production, inner tube was nested on core model before this, core model drives inner tube to turn
When dynamic, the glass fibre spiral wrap that band is tied is on the outer surface of plastic inner pipe, while along winding direction by inner tube
Outer surface heats and softens, and is squeezed the lower half portion of knot in the outer surface of plastic inner pipe with compression roller, then applies again
It covers resin adhesive liquid and stands so that glass fibre and knot thereon are impregnated with resin adhesive liquid, last coated with glass fibre reinforced plastics outer tube, with what is tied
Glass fibre and thereon knot also together curing molding be glass reinforced plastic outer tube a part.
In the utility model, the smooth interior surfaces of plastic inner pipe are highly beneficial to threading；Glass fibre with knot after molding
Knot thereon also together curing molding be glass reinforced plastic outer tube a part, integral strength is high；Half portion is forged on glass fibre
Divide in the outer surface of plastic inner pipe, increase the binding force between inner and outer pipes, inner and outer pipes are used for a long time will not delamination.
Therefore, the utility model has the characteristics that simple structure and reasonable design.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the utility model band knot glass fibre；
Fig. 2 is a kind of structural schematic diagram of the utility model band knot glass fiber winding on plastic inner pipe；
Fig. 3 is that structural schematic diagram cuts open in a kind of office of the utility model.
In figure, 1- glass fibre, 2- knot, 3- plastic inner pipe, 4- glass reinforced plastic outer tube.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment: referring to Fig. 1-Fig. 3, the utility model includes plastic inner pipe and glass reinforced plastic outer tube, the plastic inner pipe
