Description
Technical field
The present invention relates to polymeric material field, be specifically related to a kind of regeneration HDPE compatible modification regeneration PP bellows drainpipe
PP Pipe Compound and preparation method thereof.
Background technology
At present, polypropylene (PP) tubing has the advantages such as high temperature high voltage resistant, recoverable, environmentally-friendly sanitary, simple installation,
PP tubing is become, and promotion rate is very fast, preferably a kind of novel tube of development prospect.But the isotacticity of the strand of PP is relatively
Height, the sterically hindered compliance making strand of pendant methyl reduces, and meanwhile, PP is when regeneration, and its strand is
Experienced by portion fractures, therefore, regeneration PP material itself has the shortcoming such as black brittleness and environmental stress cracking resistance difference,
If regeneration PP material is made draining blowdown corrugated tube further, blowdown corrugated tube easily causes pipeline breaking because of external force.
Containing-CH in high density polyethylene (HDPE) (HDPE)2-unit, it has, and brittle temperature is low, anti-stress cracking
Feature good, that notch sensitivity is low, shear strength is high, ageing-resistant, length in service life, anti-trace ability are excellent, can be-60～60
Safe handling in DEG C temperature range；And the environmental stress cracking resistance of HDPE material is the most prominent；But, HDPE tubing
The mechanical performance of reworked material has reduction in various degree with physical and chemical performance compared with primary material, if being reused directly for ripple
The preparation of pipe, the mechanical property of corrugated tube is the most poor.
Prior art exists substantial amounts of waste and old polypropylene (PP) tubing and high density polyethylene (HDPE) (HDPE) tubing, the most real
The recycling of these waste and old tubing reworked materials existing, and strengthen the mechanical property of reworked material and physical and chemical performance becomes and needs solution badly
Technical problem.
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 regeneration HDPE compatible modification regeneration PP draining
Corrugated tube PP Pipe Compound, described PP Pipe Compound achieves waste PP tubing and the regeneration of waste HDPE tubing, and described draining
Corrugated tube PP Pipe Compound has preferable shock resistance and environmental stress cracking resistance.
Another object of the present invention is to provide above-mentioned regeneration HDPE compatible modification regeneration PP drain bellows pipe as special material
Preparation method.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of regeneration HDPE compatible modification regeneration PP drain bellows pipe as special material, described drain bellows pipe as special material presses mass fraction
It is made up of following raw material:
PP tubing reworked material 40～65 parts；
HDPE tubing reworked material 10～35 parts；
Increase firm masterbatch 15～30 parts；
Compatible modifier 5～15 parts；
Processing aid 1～4.5 parts；
Wherein, one or both during described compatible modifier is POE-g-PE, PP-g-PE graft.
HDPE has cryogenic property and the ageing-resistant performance of excellence, and PP has good rigidity and heat-resisting quantity, if by two
Person is combined with each other, and makes up mutually respective defect, collaborative play respective advantage and is then likely to form a kind of high-rigidity high-ductility, resistance to
Environment stress cracking corrugated tube of good performance PP Pipe Compound；But HDPE tubing reworked material and the mechanical performance of PP tubing reworked material
Having reduction in various degree compared with primary material with physical and chemical performance, the compatibility between the two is the most poor, how to promote this two
Plant the compatible technology solved needed for HDPE tubing reworked material and the utilization of PP tubing reworked material to realize Synergistic to become of reworked material
A difficult problem；Inventor has attempted various compatilizer to improve HDPE tubing reworked material and the phase of PP tubing reworked material in experimentation
Capacitive, but not arbitrary compatilizer can improve the compatibility of HDPE reworked material and PP reworked material, through numerous trials it
Rear discovery, when POE-g-PE graft or PP-g-PE graft being applied in HDPE tubing reworked material and PP tubing reworked material
Time, it can be good between promotion HDPE and PP tubing reworked material compatible, and can improve the impact resistance of composite
Energy and environmental stress cracking resistance.
In the present invention, described PP tubing reworked material can be the PP feed pipes such as PP-R pipe, PP-B tubing, PP-H tubing

Preferably, described HDPE tubing reworked material is at 190 DEG C, and the melt index under the conditions of load-bearing 5kg is 0.5～2g/10min；When
When the melt index of HDPE tubing reworked material is within the scope of above-mentioned, it is closer to the melt index of PP tubing reworked material,
Be conducive to improving the compatibility between bi-material.
In the present invention, the percent grafting of POE-g-PE, PP-g-PE graft and melt index are to compatible between HDPE and PP
The impact of performance is relatively big, if POE-g-PE, PP-g-PE graft differs relatively big with the melt index of HDPE and PP, and not only can shadow
Ring the processing characteristics of composite, also result in and combine uneven between graft and matrix resin, make com-patibilising effect decline；Grafting
The too high or too low compatibility that all can affect HDPE Yu PP of percent grafting of thing, and the mechanical properties decrease of composite can be caused
The most serious.
For improving elongation at break and the impact strength of corrugated tube PP Pipe Compound, it is preferable that described POE-g-PE graft
