Abstract

The invention belongs to the technical field of high polymer materials and relates to a preparation method of a pipe. The preparation method comprises the following steps of: (1) placing a compound prepreg tape in a winding device, and then enabling the compound prepreg tape to pass through each tension roller in the tension roller group sequentially; (2) pre-heating the compound prepreg tape which is treated in the step (1); (3) heating the compound prepreg tape preheated in the step (2) at a winding point; (4) winding the compound prepreg tape heated in the step (3); and (5) finally, solidifying and shaping in situ to obtain the pipe. Compared with the prior art, the preparation method of the continuous fiber-reinforced thermoplastic compound prepreg tape pipe, disclosed by the invention, has the advantages of low cost, simple equipment, short shaping period and the like; and the produced thermoplastic compound pipe has a light weight, is high-pressure resistant and anticorrosive, and can be applied to the high-end field such as petrochemical engineering.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials and relates to a method for preparing pipes. Background technique

[0002] The winding forming process has simple equipment, high efficiency and low cost, and is one of the most promising manufacturing methods for composite material forming process. Winding molding is currently mainly focused on the molding of fiber-reinforced thermosetting composite materials, mainly FRP winding pipes. The elastic modulus of FRP products is low, and some reinforcement ribs can be used to increase its rigidity, but this will increase the cost accordingly, and the long-term heat resistance of FRP products is very poor. Chinese patent CN201020596716.X uses fiberglass reinforced steel-plastic pipes, and finally tightly bonded thermoplastics on the glass fiber reinforced layer to form an outer protective layer. Therefore, this composite pipe has anti-corrosion effects and can greatly improve the pressure re...
