Description
Technical field
The present invention relates to a kind of modified material technical fields, and in particular to a kind of effective composite polyethylene material of ripple and its
Preparation method.
Background technique
Shape memory high molecule material can be made by the additional stimulation such as heat, chemistry, machinery, light, magnetic or electricity, triggering material
Response, to change the technical parameter of material, i.e. shape, position, strain etc. makes it be returned to original shape rapidly.Shape note
Recall the development of high molecular material in recent years to advance by leaps and bounds, wherein thermo-stimulative shape memory polymer material is emphasis therein.It is high
Molecular material will reach shape memory function and have to have structure phase and deformation phase.With the most use is hot system currently on the market
Tubing is irradiated by electron accelerator or cobalt source using polyethylene extrusion molding tubing, hands over moieties chain by shrink sleeve
Then connection is expanded in heated situation and is formed.The fusing point of polyethylene or more is heated to when use can revert to former pipe
Material size.
Bellows is a kind of common elastic component, it is that required function is realized using the elasticity of material, is carried in the external world
The lower shape and size for changing element of lotus effect, are returned to original state again after load removal, to realize measurement, connect
It connects, convert, compensating, being isolated, sealing, the functions such as damping.If load is excessive, it is unsuitable extensive that collapsing etc. for bellows can be directly resulted in
Multiple situation, so that bellows be made to lose the protective effects such as isolation, damping.Therefore, if shape-memory material is used for wave
Line pipe makes to collapse complete recovery when bellows is collapsed by simply heating, and such bellows can again serve to corresponding work
With.
Summary of the invention
The object of the present invention is to provide effective composite polyethylene materials of a kind of ripple and preparation method thereof.
Technical scheme is as follows:
A kind of effective composite polyethylene material of ripple, is prepared by weight by following components:
Further scheme, the polyethylene be low pressure polyethylene or high pressure polyethylene, melt flow rate (MFR) 190 DEG C/
It is 0.5~5.0g/10min under the test condition of 2.16kg.
The polyphenylene sulfide density 1.34-1.38g/cm3。
The toughener is at least one of ethylene-octene copolymer, ethylene-propylene copolymer.
The fire retardant is low halogen bromide fire retardant, phosphorus content >=9.5wt%, bromine content≤30wt%.
The compatilizer is maleic anhydride stem grafting polyolefin elastomer, maleic anhydride inoculated polypropylene, maleic anhydride grafting
The mixture of one or more of polyethylene, wherein maleic anhydride content is 1.5-3.5%.
The antioxidant be four [β-(3,5- di-t-butyl 4- hydroxy phenyl) propionic acid] pentaerythritol esters (antioxidant 1010),
β-(3,5- di-tert-butyl-hydroxy phenyl) propionic acid n-octadecyl alcohol ester (antioxidant 1076), three-(2,4- di-tert-butyls
Base) phosphite ester (irgasfos 168), at least one of double octadecyls (antioxidant DSTP) of thio-2 acid.
The lubricant is the mixing of one or both of PE wax, EVA wax, calcium stearate, ethylene Stearyl Amine
Object.
Another goal of the invention of the invention is to provide a kind of preparation method of the above-mentioned effective composite polyethylene material of ripple,
By 42-66 parts of polyethylene, 12-20 parts of polyphenylene sulfide, 12-20 parts of toughener, 6-10 parts of fire retardant, 4-8 parts of compatilizer, antioxidant
0.2-1.0 parts, 0.3-0.8 parts of addition high mixers of lubricant carry out mixing 5-15min；Then uniformly mixed material is added double
It is kneaded, squeezed out in screw extruder, obtain the effective composite polyethylene material of ripple；Wherein each extrusion zone in double screw extruder
Between extrusion temperature be 220-235 DEG C, 230-245 DEG C, 255-265 DEG C, 255-265 DEG C, 260-270 DEG C, 260-275 respectively
℃、260-275℃、265-280℃、265-280℃、270-290℃。
When composite material prepared by the present invention is heated to PE fusing point or more, due to there is polyphenylene sulfide to form net in the polymer
Shape it is evenly dispersed, although PE crystal grain melts, there is not flow regime, but the elasticity with rubber one kind, if at this time
When the techniques such as production technology, that is, external force expansion, quenching according to material contracting with heat are prepared into bellows, then bellows can have " shape
Shape memory effect " --- i.e. when it produces deformation under external force, it is heated to the fusing point of polyethylene or more, deformation
It then can be self-healing, so that bellows be made to again serve to the protective effects such as isolation, damping.
Therefore, the beneficial effects of the present invention are:
(1) thin-wall corrugated tube made from the effective composite polyethylene material of ripple of the invention is more soft, and sense of touch is good, and hinders
Fuel efficiency fruit reaches V-2；
(2) when the bellows as made from this material produces deformation under external force, it is heated to the molten of polyethylene
Or more, deformation can be self-healing, and deformation recovery rate is more than or equal to 90%, and recovery time is less than or equal to 100 seconds；Response is very
Quickly.
(3) the effective composite polyethylene material of ripple of the invention, preparation method is simple, and cost is relatively low.
