Description
Technical field
The present invention relates to plastic pipe technical field, be specifically related to a kind of enhancing HDPE double-wall corrugated pipe and preparation side thereof
Method.
Background technology
Along with the rapid growth that Chinese national economy is continual and steady, provide good macroscopic view for cities and towns infrastructure construction
Environment and broad space.Along with China is for the pay attention to day by day of environmental protection, governments at all levels of both the central and local governments have put into effect one and have been
Row water saving, the policies and regulations of pollution treatment protection environment.Supply water, water saving, draining and waste water control will become urban municipal construction from now on
Emphasis, this is that the popularization and application of heavy-caliber plastic pipe provide market development space.Due to structured wall popes can with conservation,
Reducing cost, therefore structured wall popes has become as the main product of heavy caliber draining blow-off line.China is used for draining and blowdown
The U-PVC double-wall corrugated pipe of pipeline has good rigidity, the advantages such as price is low；But the shortcoming also having low temperature impact properties difference, especially
Breakage it is very easy to when north of china in winter is constructed.And HDPE double-wall corrugated pipe has obvious advantage in low-temperature flexibility, but due to
PE material behavior, its rigidity relatively pipe of cement is poor, and the ring stiffness of tubing and creep resisting ability relatively PVC bellows is poor, at Long-Time Service
During, easily by gravity deformation, affect product service life.
Prior art seldom relates to have low-temperature flexibility, rigidity, ring stiffness and creep resisting ability simultaneously the most preferable
Strengthen HDPE double-wall corrugated pipe；Therefore, exploitation one strengthens HDPE double-wall corrugated pipe, has great significance.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of enhancing HDPE double-wall corrugated pipe and preparation thereof
Method, this enhancing HDPE double-wall corrugated pipe has preferable low-temperature impact toughness, good rigidly, ring stiffness is high, creep resisting ability is excellent
Different, there is relatively low cost simultaneously, have broad application prospects.
It is an object of the invention to be achieved by following technical solution:
A kind of enhancing HDPE double-wall corrugated pipe, the formula of described HDPE double-wall corrugated pipe is by the raw material group of following weight parts
Become:
High density polyethylene (HDPE) 100 parts；
Wood powder 40～60 parts；
Titanate coupling agent 1～3 parts；
Ethylene propylene diene rubber 7～9 parts；
Wherein, the mesh number of described wood powder is 80～110 mesh；The Mooney point of described ethylene propylene diene rubber is 70～90, ethene
Propylene is than being (55:45)～(65:35)；
The preparation method of described HDPE double-wall corrugated pipe comprises the steps:
Two-stage assembled pulse air-flow is i.e. used to be dried described wood powder employing dedicated drying production line, detailed process
For: dry 1～3 hour at 120～180 DEG C so that it is moisture is less than 300mg/kg, mix with titanate coupling agent after being cooled to normal temperature
Close, be heated to 60～70 DEG C, dispersed with stirring 5～7 minutes under 800～1100 revs/min of speed, it is subsequently adding ethylene-propylene-diene monomer
Glue, cools down after stirring automatically；Then above-mentioned compound is mixed with high density polyethylene (HDPE), be then sent to extrusion
Machine, plasticizing extrusion, mould molding i.e. obtain enhancing HDPE double-wall corrugated pipe.
In the present invention, have that yield is big but baking temperature can not be the highest, baking temperature mistake owing to wood powder is dried
Height is the most on fire, uses traditional drying equipment to be difficult to meet the big requirement produced.Therefore the wood powder in the present invention is dried employing
Special drying production line, i.e. uses two-stage assembled pulse pneumatic conveying drying.When dry, wet wood powder is entered continuously by feeder
Enter in the drying tube of first order pulsed pneumatic dryer lower end.In drying tube, wood powder is broken up by high velocity, hot air and upwards moves
Dynamic, material contacts fully with air-flow, and moisture is by rapid evaporation.Wood powder by after drying tube by cyclone collection, then enter
Enter second level pulsed pneumatic dryer, be again dried, effectively extend the drying time of material and achieve well
Effect.
Inventor finds in experimentation, and the mesh number of wood powder is to the low-temperature flexibility of tubing, rigidity, ring stiffness and anti-compacted
Become capacity bigger；Wood mesh is less, and surface roughness is high, short texture, owing to high density polyethylene (HDPE) is nonpolar, and
Wood powder is polarity, both poor compatibility, and high density polyethylene (HDPE) melt is difficult in wood powder infiltration, easily forms sky around wood powder
Hole defect；And when wood mesh is excessive, wood powder particle diameter is little, easily reuniting, these defects form stress and concentrate, in less effect
Under, be easily broken off, and the wood powder of 80～110 mesh, moderate in grain size, good with high density polyethylene (HDPE) compatibility, now impact strength and
Bending strength is best.
It is further preferred that the mesh number of described wood powder is 100 mesh.
Preferably, described high density polyethylene (HDPE) is polyethylene PN049.
Inventor finds when adding the ethylene propylene diene rubber of relatively high Mooney, can significantly improve the hot strength of tubing
And tearing strength, and in the molten state, it is possible to preferably mix with filler；It addition, ethene is different with the ratio of propylene, right
Pipe performance also has certain impact, and when propane ratio is too high, the hot strength of tubing is higher, but low-temperature characteristics is poor, and third
When alkene ratio is higher, benefit is exactly more preferable processing characteristics, more preferable low-temperature characteristics and preferably compressive deformation etc., but stretching
Intensity is relatively low.Considering, the Mooney point of ethylene propylene diene rubber that the present invention uses is 70～90, ethylene, propylene than for (55:
45)～(65:35)；It is further preferred that the Mooney point of described ethylene propylene diene rubber is 90 Mooneys (ML1 ± 4 125 °), ethene
Propylene is than for 60:40.
Compared with prior art, there is advantages that the HDPE double-wall corrugated pipe that the present invention prepares
In low-temperature flexibility, not only there is obvious advantage, the content of EPDM, its Mooney point and selection EPDM in being filled a prescription by regulation simultaneously
In ethylene, propylene ratio, and the good rigidly of HDPE double-wall corrugated pipe for preparing of the selection etc. of wood mesh, ring stiffness are high,
Creep resisting ability is strong, during Long-Time Service, because of gravity deformation, thus will not extend the service life of product；Produce simultaneously
Low cost, has broad application prospects.
