A kind of fiber reinforcement type insulation thermoplastic composite pipe and preparation method thereof

The invention belongs to engineering material field, be specifically related to a kind of fiber reinforcement type insulation thermoplastic composite pipe, and further disclose its preparation method.Fiber reinforcement type of the present invention insulation thermoplastic composite pipe, comprises pipe (1), fiber-reinforced layer (2), thermoplastic clad (3), expandable plastic thermal insulation layer (4) and thermoplastic outer tube (5) in the thermoplastic that sets gradually from the inside to the outside; In described thermoplastic, pipe (1), thermoplastic clad (3) and thermoplastic outer tube (5) are independent of each other for extrude obtained by thermoplastic modification plastic warp.Fiber reinforcement type insulation thermoplastic composite pipe of the present invention, owing to being provided with the thermoplastic modification plastic clad by thermoplastic resin and modifier modification especially, make to combine closely between fiber and plastics, limit fiber braiding layer generation layering, cracking and loosening phenomenon, improve the reliability of fiber braiding layer.
