Background technology
Plastic pipe has many advantages, such as that light, corrosion-resistant, service life is long, but with traditional piping material (such as pipe of concrete)
It compares, there are certain gaps in use intensity.This defect greatly limits the popularization and application of plastic pipe.Fiber has
The features such as intensity is high, wear-resisting, impact resistance is good, therefore the enhancing for being commonly used for plastic pipe is modified, and is connected especially by addition
Continuous fibre bundle enhances plastic pipe, toughening modifying.
Patent of invention CN201293157Y is disclosed a kind of " PE coiled composite tubes ".The continuous tow referred in patent increases
The production stage of strong plastic pipe is as follows：It first passes around extrusion die and squeezes out embryo in circular pipe, after sizing to be cooled outside it
The continuous woven fabric in surface winds one layer of fibre bundle, enters back into extruder and coats one layer of resin, again cooling and shaping, forms one kind " three
Mingzhi " structure.This mode of production has the disadvantage that：(1) product limitation, can only be in solid wall, circular plastic pipe
Upper realization can not be applied on plastic tubing of hollow structural wall, especially in I-shaped steel type, the structure of ripple type, cyclic rib type
Wall tube material；(2) low production efficiency, the production line length of tubing, equipment is various, and the production cycle is long, and product quality is not easy to stablize control
System；(3) production energy consumption is high, which needs 2 moulding process；(4) binding force between fiber and resin is limited, by
It is low to be easy mutually stripping, product service life for fiber and resin when outer force effect.
Patent of invention CN2601817Y is disclosed a kind of " roving glass fiber spiral online mixed round plastic pipe extruder head ".
The head can be mounted on various general-purpose plastics pipe extruders, and glass fibre can continuously be cut into the short fibre of certain length
Dimension, makes glass fibre be mixed into plastic melt, then makes blend melt around tubing plug axis helical flow.This method is realized
Uniform between fiber and resin melt mixes, and simplifies the production procedure of fiber reinforcement tubing, reduces production cost；Together
When can fiber be orientated along pipe wall screw.But the problem of this mode of production maximum is cut out along with continuous fiber
It is cut into the staple fiber of 3~5mm, room for promotion of the fiber to tubing impact strength, tensile strength is greatly lowered.
