Abstract
The present invention relates to a kind of enhancing double-wall corrugated pipes, PPR material are blended into HDPE, PPR material have intensity high, the feature that rigidity is big, heat resistance is good, good stability of the dimension, low-temperature flexibility are splendid, and it is polyolefine material, it can fully be mixed with HDPE material, strand connects, the ring stiffness of tubing can be more effectively improved, while its proportion is only the 45% of calcium carbonate, can significantly reduce the meter Chong of tubing, directly reduce unit materials dosage, manufacturing cost is reduced, while blast filling master batch is added, outside is bright.
Description
Technical field
The present invention relates to bellows field more particularly to a kind of enhancing double-wall corrugated pipes.
Background technology
Three big main performance index of bellows are ring stiffness, impact resistance, ring flexibility.It is now relatively common to be
HDPE is managed, HDPE, that is, high density polyethylene (HDPE), is that a kind of crystallinity is high, nonpolar thermoplastic resin.HDPE in impact property and
It is excellent in ring flexibility, but ring steel is poor, and traditional double wall bellows needs to add a high proportion of carbon to improve the ring stiffness of tubing
Sour calcium filling master batch, main ingredient is calcium carbonate, than great, causes tubing weight big, while the ring that can reduce tubing is flexible
And impact resistance is all that tube wall is done thickness, manufacturing cost is caused to increase to overcome its above weakness；Due to being added excessively
Filler material, it is difficult to fully be merged with HDPE material, strand is imperfect, and tubing appearance is crude.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of enhancing double-wall corrugated pipe.
The present invention is achieved through the following technical solutions：
A kind of enhancing double-wall corrugated pipe, by weight percentage, including following components：
Said program also has a kind of preferred embodiment, by weight percentage, including following components：
Wherein it is added to suitable blast filling master batch TB01-F.
Compared with prior art, the beneficial effects of the invention are as follows：On the basis of traditional double wall bellows, PPR is expected
It is blended into HDPE, PPR material have intensity high, the spy that rigidity is big, heat resistance is good, good stability of the dimension, low-temperature flexibility are splendid
Point, and be polyolefine material, it can fully be mixed with HDPE material, strand connects, and can more effectively improve the ring of tubing
Stiffness, while its proportion is only the 45% of calcium carbonate, can significantly reduce the proportion of tubing, directly reduces unit materials dosage,
Manufacturing cost is reduced, while blast filling master batch is added, outside is bright.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
High density polyethylene (HDPE) (High Density Polyethylene, referred to as " HDPE "), be a kind of crystallinity it is high,
Nonpolar thermoplastic resin.The milky appearance of ortho states HDPE, in meagre section in a degree of translucent.PE has
There is the characteristic of excellent resistance to most of lives and chemicals for industrial use.Some kinds of chemicals will produce chemical attack, such as
Corrosive oxidation agent (concentrated nitric acid), aromatic hydrocarbon (dimethylbenzene) and halogenated hydrocarbon (carbon tetrachloride).The polymer is non-hygroscopic and has
Steam-preventing, can be used for packaging applicationss.HDPE has good electrical property, especially dielectric strength high, makes it very
Suitable for electric wire.In to high molecular weight grades have fabulous impact resistance, room temperature even under -40F low temperatures
So.
PPR (polypropylene random), it is good to be called atactic copolymerized polypropene (PPR) its toughness of products, and intensity is high,
Processing performance is excellent, and creep-resistant property is good under higher temperature, and has the advantages that the distinctive high transparency of atactic copolymerized polypropene.One
As say, the flexibility of random PP copolymers ratio PP homopolymers it is good and rigidity it is low.They are when temperature is down to 32 °F, moreover it is possible to keep
Moderate impact strength, and when temperature is down to -4 °F, serviceability is with regard to limited.Copolymer bending modulus (1% strain when
Secant modulus) within the scope of 483~1034MPa, and homopolymer is then within the scope of 1034~1379MPa.PP copolymer materials
Influence of the molecular weight to rigidity is big not as good as PP homopolymers.Nicked cantilever-type impact strength is generally in 0.8~1.4 English
In the range of ruler pounds per inch.Random PP copolymers are to acid.Alkali, alcohol, low boiling point hydrocarbon cosolvent and many organic chemistry
The effect of product has very strong resistance.At room temperature, PP copolymers are substantially insoluble in most of organic solvents.Moreover, when being exposed to
Soap, soap solution.When in water-based reagent and alcohols, environment stress fracture damage can occurs in they not as other many polymer
It is bad.When with certain chemical contacts, especially liquid hydrocarbon.Chlorinatedorganic and strong oxidizer can cause face crack or molten
It is swollen.Non-polar compound generally is easier to be absorbed by polypropylene than polar compound.Its molecule only has carbon, protium, does not have
Harmful poisonous element exists.Therefore, PPR material are blended into HDPE, the case where not increasing significantly thickness under table, can be had
Effect improves the ring stiffness of tubing.
