Abstract
The present invention relates to a kind of low-temperature resistance PE composite materials, are made of the component of following parts by weight: PE is 60 parts -80 parts；Hydrogenated styrene-butadiene block copolymer is 6 parts -12 parts；PBT is 1 part -3 parts；Antioxidant is 0.1 part -0.5 part；Lubricant is 0.1 part -0.3 part.SBES is evenly distributed in the continuous phase of PE formation as dispersed phase, when by external impacts, the SEBS elastomer particles being dispersed in PE resin can absorb a large amount of impact energy, so that the low-temperature flexibility of PE composite material be made to increase by causing crazing and inducing shear band；In addition the presence of chemical bond limits the Entropy Changes of each block between SBES difference block, and block copolymer can generate microcosmic mutually separation, and form the domain structure of very little, and this domain structure is less than the wavelength of light.When crystalline size is less than visible wavelength, light does not occur to reflect and reflect, this can improve the transparency of material.
Description
Technical field
The invention belongs to technical field of polymer materials, a kind of low-temperature resistance PE composite material and its preparation side are particularly related to
Method.
Background technique
Polyethylene (PE) have it is light, nontoxic, odorless, chemical stability is good, and electrical insulation capability is good, and insoluble at normal temperature
In common solvent, the advantages that water imbibition is small.In recent years oneself becomes the kind that growth rate is most fast in five big resins for universal use, is answered extensively
For fields such as chemical industry, building materials, household electrical appliances, automobiles, become the resins for universal use of yield first, but polyethylene itself also there are many deficiencies
Place, mainly impact resistance is poor under cryogenic conditions, and the transparency is poor, and appearance lacks aesthetic feeling, so that PE is in packaging, Medical treatment device
The application in the fields such as tool, household supplies is restricted.
Summary of the invention
The object of the present invention is to provide a kind of low-temperature resistance PE composite materials, to improve the low-temperature impact resistance of PE composite material
Energy and the transparency.
The present invention is achieved by the following technical solutions:
A kind of low-temperature resistance PE composite material, is made of the component of following parts by weight:
The PE is linear low density polyethylene.
The PE is LLDPE 7042.
The antioxidant is three (2,4- di-t-butyl) phenyl-phosphites, four [β-(3,5- di-tert-butyl-hydroxy phenyl)
Propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one of 6- (3,5- di-t-butyl -4- hydroxyphenylmethyl) benzene or more
Kind.
The lubricant is one of zinc stearate, calcium stearate or potassium stearate or a variety of.
A kind of preparation method of the low-temperature resistance PE composite material of any of the above-described, comprising the following steps:
(1) weigh 60 parts -80 parts of PE, 6 parts -12 parts of SEBS, 1 part -3 parts of PBT, 0.1 part of -0.5 part of antioxidant,
0.1 part of -0.3 part of mix lubricant simultaneously stirs evenly, and obtains mixture；
(2) by mixture extruding pelletization obtained in step (1) to get arrive PE composite material.
Preferably, the step (2) specifically: mixture obtained in step (1) is put into double screw extruder
Extruding pelletization in hopper, wherein the double screw extruder includes six humidity provinces sequentially arranged, area's temperature 140~160
DEG C, two 170~200 DEG C of area's temperature, three 170~200 DEG C of area's temperature, four 170~200 DEG C of area's temperature, five area's temperature 170~200
DEG C, six 170~200 DEG C of area's temperature, 170~200 DEG C of head temperature；200~260r/min of screw speed.
The beneficial effects of the present invention are:
SBES is evenly distributed in the continuous phase of PE formation as dispersed phase, when by external impacts, is dispersed in PE tree
SEBS elastomer particles in rouge can absorb a large amount of impact energy, to make PE by causing crazing and inducing shear band
The low-temperature flexibility of composite material increases.
