Abstract
A material special for plastic pipes comprises 100 parts of a matrix resin, 0-60 parts of inorganic powder, 1-10 parts of a compatilizer, 1-5 parts of a coupling agent, 0.1-1 part of a lubricant, 0.1-1 part of an anti-oxidant and 0.1-1 part of a nucleating agent. A preparation method of a continuous-fiber-bundle-enhanced double-wall winding pipe based on the material special for plastic pipes comprises: leading continuous fiber bundles through a fiber penetration hole and a fiber penetration channel of a neck die, allowing the continuous fiber bundles to join a resin at the end port of the neck die, so that the continuous fiber bundles can be uniformly covered, and carrying out extrusion and vacuum sizing to finally form a continuous-fiber-bundle-enhanced double-wall winding pipe having a multi-layer composite structure and made from a hollow square pipe through spiral winding and welding with a plastic hot-melt adhesive. The continuous-fiber-bundle-enhanced double-wall winding pipe has advantages of light weight, good rigidity and tensile resistance, impact resistance, creep resistance and stress relaxation damage resistance, and can be widely applied to fields including water supply and drainage, agricultural irrigation, gas transmission, and engineering of mining, oil field, and chemical industry.
Description
Technical field
The present invention relates to tubing, more particularly to a kind of plastic pipe PP Pipe Compound and continuous tow enhancing binary wall twisting and pipe
Preparation method.
Background technology
Binary wall twisting and pipe is by screw extruder melting, extrusion, Jing vacuum sizings, winding, cooling etc. by resin
Step, finally obtains the plastic pipe with I-shaped die structural walls.Common binary wall twisting and pipe has polyethylene double-wall
Winding pipe, polypropylene double-walled winding pipe, PVC dual-wall winding pipe.Compared with bellows, riffled tube, have
The binary wall twisting and pipe of I-shaped die structural walls has bigger the moment of inertia, can accomplish higher strength and stiffness.By
Relatively low to equipment degree of dependence in Wrapping formed production technology is used, tubing bore is maximum up to 3000mm.
As pipe ring stiffness and bore are constantly improved, tubing weight rises sharply, raw and auxiliary material consumes huge, production control
Difficulty is high, tubing ring is flexible and impact resistance declines, and limits the application of large-caliber double-wall winding pipe.Fiber
As a kind of inorganic reinforcement, there is high-modulus, high intensity, corrosion-resistant, excellent in dimension stability,
Largely can improve mechanical property, the dimensional stability of matrix resin.
Patent of invention CN102691832B is reported " fiberglass reinforced HDPE binary wall twisting and pipes and preparation method thereof ".
The tubing is welded by fiberglass reinforced HDPE plastic pipe Jing spiral windings and with plastic hot melt glue, glass therein
Fibre strengthens hollow, rectangular glass of weight percent content of the HDPE plastic pipe for roving glass fiber between 5～40% and increases
Strong HDPE plastic pipe.The shock resistance of the fiberglass reinforced tubing of the invention, anti-scratch, anti-Slow Crack,
Environmental stress crack resistance is good, there is enough seam tensile strengths.But the roving glass fiber that the tubing is adopted is in process engineering
In be broken into short fibre different in size, certain humidification is played to tubing, but tubing entirety cannot be improved
Pliability, still there is more obvious creep and stress relaxation destruction in tubing.
Utility model patent CN204372370U is reported " the hollow binary wall twisting and pipes of HDPE ".The tubing is main
It is made up of rubber bound layer and the winding pipe being arranged in rubber bound layer.Reinforcement is provided with inside winding pipe, can be with
Improve the intensity of winding pipe, it is ensured that the bulk strength of body simultaneously accomplishes bigger bore；The glass that body outside is arranged
Overcoat can further improve the intensity of body, prevent the impact failure of external force.But this tubing need to be in winding
Outer tube layer coating, bonding layer of glass fiber overcoat, complex process, consumptive material is big, high cost；Reinforcement and glass are anti-
The design of sheath can strengthen the rigidity of tubing, but the lifting effect of tubing pliability and shock resistance is failed to understand
It is aobvious.
