Problems solved by technology

There is a fatal shortcoming in the steel wire wound reinforced plastic composite pipe and its production process equipment: the bonding strength between the steel wire layer and the plastic inner and outer pipe is poor, and it will cause delamination due to thermal expansion and contraction and alternating loads during long-term use, which greatly Reduce product performance and use effect, or even scrap

Abstract

The invention relates to a production method and a production device for a thermoplastic wound reinforced plastic composite tube. The production device comprises an inner tube extrusion module, a reinforcing layer winding module, an outer tube extrusion module and a cutting module from left to right in order, wherein the inner tube extrusion module is used for extruding an inner tube; the reinforcing layer winding module is used for winding and compositing a continuous fiber reinforced thermoplastic composite material around the inner tube so as to form a reinforcing layer; and the outer tube extrusion module is used for extruding an outer tube and composting the outer tube onto the surface of the reinforcing layer. A product produced by adoption of the method and the device is high in strength. The thickness of a plastic tube wall under same pressure conditions can be largely reduced, thus saving the cost.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and materials, and relates to a production device and a preparation method of a thermoplastic winding reinforced plastic composite pipe. Background technique [0002] Due to the low strength of the plastic pipes in the prior art, the pipes can only be used in the field of low-pressure pipelines. At the same time, they require a large wall thickness and high cost. This disadvantage is more obvious in large-diameter pipelines. Therefore, reinforced plastic pipes (abbreviated as RTP pipes) came into being, and the existing reinforced plastic composite pipes are mainly steel wire wound reinforced plastic composite pipes. [0003] Existing steel wire winding reinforced plastic composite pipe production equipment mainly includes an inner pipe extrusion molding device, a left-handed steel wire winding machine, a heating device, a right-handed steel wire winding machine, an adhesive extruder...
