Abstract
The utility model provides a fiber compound drainage pipe. The fiber compound drainage pipe comprises a plastic board strip, wherein edges of the plastic board strip are mutually overlapped or melted to form an inner pipe wall; the outer side of the inner pipe wall is coated with a fiber layer; and an outer pipe wall is formed on the outer side of the fiber layer by rubber coating. The fiber compound drainage pipe has the advantages that: 1, with adoption of the fiber layer, a steel strip is not required, so that the raw material is saved, and the manufacturing cost of the pipe is greatly reduced; 2, with the coating of the fiber layer, the pressure resistance at a melting position can be greatly improved; and 3, the fiber layer can be compounded with the plastic board strip well, so that the service life of the pipe is prolonged.
Description
Technical field
The utility model relates to the tubing technical field, refers in particular to a kind of fiber composite waste pipe.
Background technique
Is two great development trend to mould Dai Gang with the development pipeline transport; Wherein, the high performance of plastic tube, characteristics such as high-strength, lightweight, wear-resisting, anti-corrosion, inexpensive and heavy caliber have obtained using widely; Because this type of tubing rigidity and temperature tolerance are poor, can't be used for fields such as oil transportation and high pressure water delivery; And that the characteristics of metal tube are mechanical strengths is better, can not be out of shape, but because its poor corrosion resistance; Life-span is short, leaks the problems such as polluted water of getting rusty through regular meeting; What adopt in the market is that steel is moulded the composite, water-drain pipe mostly, and the structure of such tubing is: when twining, the stiffening rib processed by steel band is filled in the hollow wall inter-sync of past plastics strip with a kind of plastics strip that hollow wall is arranged; Press formation pipe outer wall through covering rubber-surfaced roll more at last; The shortcoming of this class formation is: because steel band is wrapped in the part, only strengthened the local resistance of tubing, the strip weld breaks easily; And the expansion coefficient of steel band and plastics is different, can not be combined as a whole.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, provides that a kind of anti-pressure ability is strong, long service life, the fiber composite waste pipe that is difficult for breaking.
For realizing above-mentioned purpose, the technological scheme that the utility model provided is: a kind of fiber composite waste pipe, and it includes the plastics strip, and the plastic board belt edge overlaps each other or mutual welding forms inner tube wall, and the described inner tube wall outside is coated with layer of fibers; The layer of fibers outside forms the pipe outer wall through covering glue.
Described plastics strip weld outer wall is coated with layer of fibers, and layer of fibers is outer to be formed with the welding layer through covering glue.
Described layer of fibers is fleece or fiber band.
The advantage of the utility model is: the first, adopted layer of fibers after, no longer need winding steel, saved raw material, greatly reduce the manufacture cost of tubing; The second, through fibrolaminar coating, can strengthen the anti-pressure ability of weld greatly; The 3rd, layer of fibers can be good at combining with the plastics strip, prolongs the working life of tubing.

Embodiment
Below in conjunction with institute's drawings attached the utility model is described further, the preferred embodiment of the utility model is:
Embodiment 1: the double-walled type
Referring to accompanying drawing 1 and accompanying drawing 2, the described fiber composite waste pipe of present embodiment is a double-walled type tubing, and it includes plastics strip 1, and plastics strip 1 edge overlaps each other or mutual welding forms inner tube wall, and the inner tube wall outside is coated with layer of fibers 2; Layer of fibers 2 is fleece or fiber band, and fleece or fiber band are wrapped in the spine outside; Layer of fibers 2 can be strengthened the anti-pressure ability of weld greatly, prevents that tubing from breaking.Layer of fibers 2 outsides form pipe outer wall 3 through covering glue.This programme does not need winding steel again, has saved raw material, greatly reduces the manufacture cost of tubing.
The composite, water-drain pipe of said structure is accomplished through following steps:
First step: HDPE or PVC plastics are carried out modification through modified device; And be made into plastics strip 1;
Second step: with the sidewall of HDPE after the modification of spiral Wiring apparatus coiling or PVC plastics strip 1, make its mutual bonding formation inner tube wall, or with the edge of the plastics strip bonding formation inner tube wall of making contact each other;
Third step: through heating plant the outer surface of inner tube wall is heated to the molten shape of training, twines on the outermost surface that is coated on inner tube wall fleece 2 and roll extrusion then;
The 4th step: on fleece 2, cover glue and roll extrusion and form pipe outer wall 3;
The 5th step: the composite, water-drain pipe fixed length cutting that will accomplish the 4th step.
Embodiment 2: the double-walled type
Referring to accompanying drawing 3 and accompanying drawing 4, different is for present embodiment and embodiment 1: plastics strip 1 weld outer wall is coated with layer of fibers 2, and layer of fibers 2 is formed with welding layer 4 through covering glue outward.Present embodiment can increase the soundness of strip weld greatly, makes the longer service life of tubing.
Embodiment 3: single wall shape
Referring to accompanying drawing 5 to accompanying drawing 9; Different is for present embodiment and embodiment 1: the tubing of present embodiment is the single wall type; Spine's shape of plastics strip 1 can be square, trapezoidal, semicircle, ellipse or triangle, and layer of fibers 2 coats the spine and the weld of plastics strip 1 fully.
Embodiment 4: square tube strip shape
Referring to accompanying drawing 10, accompanying drawing 11, different is for present embodiment and embodiment 1: plastics strip 1 is square tube shape, and the mutual bonding formation inner tube wall of plastics strip 1 sidewall covers rubber-surfaced roll again and presses behind covered fiber layer 2 on the inner tube wall outer surface.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
