Abstract
The invention relates to a reinforced plastic tube and a manufacturing method thereof; a pipe wall is provided with three layers which are fixed together in sequence from inside to outside; the innermost layer is formed by alternatively winding long fibers which are wound in a radial direction and soaked in thermoplastic plastics and long fibers which are wound in an axial direction and soaked in the thermoplastic plastics; the middle layer is formed by polycarbonate (PC) plastics; and the outermost layer is formed by the thermoplastic plastics on the innermost layer.
Description
Technical field
The invention belongs to polymeric material field, refer to a kind of plastic tube, refer to especially a kind of enhanced plastic pipe and preparation method.
Background technique
The fibre reinforced composites pipe that now uses, when using as pressure-resistant pipeline, bearing capacity is not enough.In order to improve the bearing capacity of this class plastic tube, there is technology to propose to use fiber as reinforcing material and axially strengthens and radially enhancing, no matter and the employing fibre reinforced materials is braiding or twines, the level separation problem all after pressure-bearing, occurs, thereby bearing capacity is restricted.
Prior art proposes, and adopt the mode of wire or metal tape to improve the intensity of plastics, and this technology has been applied now, but the defective of this technology is, the weight of plastics increases, and uses metal, and decay resistance is not high.
Summary of the invention
The objective of the invention is to propose a kind of enhanced plastic pipe, by the technical program, use that can alternative metals and realize the high bearing capacity of plastic tube.
The present invention is achieved by the following technical solutions:
A kind of enhanced plastic pipe, its tube wall from inside to outside is disposed with three-decker and is fixed together;
Innermost layer for heat of immersion thermoplastic plastic after radially being twined rear heat of immersion thermoplastic plastic and long fibre by long fibre and axially twining mutually alternately winding form; Described mesosphere is comprised of the PC plastics; Described outermost surface is comprised of the thermoplastic of innermost layer.
Described long fibre is one or both combinations in glass fibre, the carbon fiber.
Described thermoplastic polyethylene, polypropylene or PVC＝polyvinyl chloride.
Described outermost thickness is the 1/3-1/5 of PC resin layer thickness.
Described preparation method:
At first long fibre heat of immersion thermoplastic plastic radially is wound in the outer surface of pipe die, and then long fibre heat of immersion thermoplastic plastic axially is wound in the radially outside of winding layer, replaces according to this winding;
Then with the outside of PC plastic-coated in above-mentioned long fibre winding layer;
To carry out shaping through the outer diameter tube shaping mould be used to the skin that floods long stapled thermoplastic and coat again the PC resin at last, cold solid moulding;
After cooling, cutting, obtain finished product again after from mould, pulling out.
The beneficial effect that the present invention compares with prior art is:
In the composite pipe of the present invention, with PC resin alternative metals material, reduced cost of production; Simultaneously, the skin use polyethylene at tube wall has guaranteed decay resistance.And the intensity of the intermediate portion PC resin of tube wall guarantees the intensity of pipeline.
Description of drawings
Fig. 1 is the schematic cross-section of enhanced plastic pipe of the present invention.
