Abstract
The present invention relates to a kind of low-temperature impact resistance clear PE composite material, it is made of the component of following parts by weight：PE is 60 parts 80 parts；AES is 5 parts 10 parts；Hydrogenated styrene butadiene block copolymer is 6 parts 12 parts；Antioxidant is 0.1 part 0.5 part；Lubricant is 0.1 part 0.3 part.SBES is evenly distributed on as dispersed phase in the continuous phase of PE formation, when being subject to external impacts, the SEBS elastomer particles being dispersed in PE resins can absorb substantial amounts of impact energy, so that the low-temperature flexibility increase of PE composite materials by triggering crazing and inducing shear band；In addition the presence of chemical bond limits the Entropy Changes of each block between SBES differences block, and block copolymer can produce microcosmic phase 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 is not reflected and reflected, this can improve the transparency of material.
Description
Technical field
The invention belongs to technical field of polymer materials, particularly relates to a kind of low-temperature impact resistance clear PE composite material.
Background technology
Polyethylene (PE) have it is light, nontoxic, odorless, chemical stability is good, and electrical insulation capability is good, and insoluble at normal temperatures
In common solvent, the advantages that water imbibition is small.In recent years become the kind that growth rate is most fast in five big resins for universal use, extensively should
For fields such as chemical industry, building materials, household electrical appliances, automobiles, become the resins for universal use of yield first, but polyethylene also there are many deficiencies in itself
Impact resistance is poor under part, mainly 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.
The content of the invention
The object of the present invention is to provide a kind of low-temperature impact resistance clear PE composite material and preparation method thereof, answered with improving PE
The low-temperature impact property and the transparency of condensation material.
The present invention is achieved by the following technical solutions：
A kind of low-temperature impact resistance clear 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 phenyls)
Propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one kind or more in 6- (3,5- di-t-butyl -4- hydroxyphenylmethyls) benzene
Kind.
The lubricant is the one or more in zinc stearate, calcium stearate or potassium stearate.
The beneficial effects of the invention are as follows：
SBES is evenly distributed on as dispersed phase in the continuous phase of PE formation, when being subject to external impacts, is dispersed in PE trees
SEBS elastomer particles in fat can absorb substantial amounts of impact energy, so that PE by triggering crazing and inducing shear band
The low-temperature flexibility increase of composite material.
