Embodiment 1

[0098] A thermoplastic continuous fiber prepreg tape high-strength pipe, including an inner layer pipe 1, a core layer 2 and a surface layer pipe 3 that are sequentially sleeved from the inside to the outside, such as figure 1 As shown, the specific structure is:

[0099] The inner tube 1 is made of melted thermoplastic and extruded. The inner tube 1 is single-layer or double-layer; the core layer 2 is made of thermoplastic continuous fiber prepreg tape, and the core tube 2 includes at least one layer; the surface layer tube 3 It is made of melted thermoplastic and extruded, and the surface layer tube 3 is solid or foamed;

[0100] When the inner tube 1 is a single layer, the wall thickness of the inner tube 1 is 2 mm to 6 mm, the material of the inner tube 1 is the same as that of the core layer 2, and the inner tube 1 is extruded by a single-screw extruder, Vacuum sizing box is made after cooling, which plays the role of winding prepreg tape inner mold and pipe inner wall ...

Abstract

The invention relates to the tubing product field produced by substance in plastic or plastic state, in particular to a high-strength pipe made by thermoplastic continuous fiber prepreg tapes and a manufacturing method and manufacturing equipment.The high-strength pipe made by thermoplastic continuous fiber prepreg tapes comprises an inner layer pipe (1), a core layer (2) and a surface layer pipe (3), all of which are sequentially sleeved from the inside to the outside. The manufacturing method for high-strength pipe made by thermoplastic continuous fiber prepreg tapes is characterized by comprising following steps: heating, fusion, extrusion, cooling and cutting.The manufacturing equipment for high-strength pipe made by thermoplastic continuous fiber prepreg tapes is characterized by comprising an extruder and a co-extrusion composite die which are arranged in sequence. The high-strength pipe is overpressure resistant, highly-rigid and is low in expansion.

Description

technical field [0001] The invention relates to the field of pipe products produced by plastic or materials in a plastic state, in particular to a high-strength pipe with thermoplastic continuous fiber prepreg and its manufacturing method and manufacturing equipment. Background technique [0002] Polyolefin thermoplastic pipes have the advantages of no rust, corrosion resistance, long service life, energy saving, recyclable reuse, etc., and are very popular in the market. Pipeline and other fields have been widely promoted and applied. [0003] Compared with composite material systems, pure plastic pipes have low tensile strength, low ring stiffness, low creep resistance, and high expansion disadvantages, such as: 1. Polymer materials are prone to creep under temperature and pressure, resulting in over time The extension of the pipeline will gradually reduce the pressure of the pipeline. In order to make the plastic pipeline last long enough, the pipeline manufacturer incre...
