Description
Technical field
The present invention relates to the preparation method of a kind of composite pipe, belong to tubing technical field.
Background technology
Carrying roller used by numerous domestic conveying machinery industry has steel pipe, nylon tube, steel to be cladded with rubber tube, steel sleeve PE at present
The kinds such as pipe, simple use steel pipe do carrying roller exist easily get rusty, frictional resistance big and to defects such as conveyer belt serious wear；And make
Making carrying roller with nylon tube, producing length can only be within 500mm, once lengthen, can not carry bigger load；Steel pipe is cladded with
Although rubber is elastic preferably, but equally exists the defect that frictional resistance is big；And use steel pipe overcoat polyvinyl piping materials, although at dress
Timing can use interference fit to make minimizing gap between steel pipe and the polyethylene tube of overcoat, but rubs owing to passing through in running
Can produce certain heat after wiping, and polyethylene cannula external diameter after being heated expands, thus skidding occur, service life is subject to
To certain impact.
Summary of the invention
It is an object of the invention to overcome defect of the prior art, it is provided that the system of a kind of novel anticorrosion composite pressure pipe material
Preparation Method, tubing prepared by described method have wear-resisting, be not easily stripped the characteristics such as high with impact strength.
