Description
Technical field
The invention belongs to polymeric material field, particularly to a kind of composite polyethylene material and preparation method thereof.
Background technology
Packaging material, mainly for the manufacture of packing container, packages printing, packed and transported etc., according to for material, mainly have
The main packaging material such as metal, plastics, glass, pottery, paper, fibrous material, composite, according to different demands, packing timber
Material mainly need to possess that thickness is thin, appearance transparent, nontoxic, tasteless, safety is good, easy to use, high, good the returning of anti-buffer intensity
Shrinkage, resistance to scraping, anti-tear performance is good and performance ratio is high.
Polyethylene is to be formed by vinyl monomer polymerization, because of its molecular weight height, chain structure difference, can be divided into high-density polyethylene
Alkene, Low Density Polyethylene and linear low density polyethylene.Low Density Polyethylene density is relatively low, and softness is good, is mainly used as moulding
Poly-bag, film for agricultural use etc..High density polyethylene (HDPE) has preferable heat resistance, can intercept greasy dirt and steam.The poly-second of linear, low density
Alkene is the copolymer that ethylene is polymerized in the presence of a catalyst with a small amount of senior Α-alkene.Due to these features of polyethylene,
Become the research focus of thin-film material.
Summary of the invention
The invention provides a kind of composite polyethylene material and preparation method thereof, the composite polyethylene material of the present invention has
Good electrical insulating property, mechanical strength, impact resistance and cold tolerance, can be by being blow molded, being molded and prolong the technological formings such as pressure, system
After becoming film article, its lustrous surface is good, overcomes the low-temperature flexibility of original polythene material and the problem that fragility is bigger.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of composite polyethylene material, is made up of the component comprising following weight portion:
Polyethylene 70-85 part,

Under, react 5-8 hour, in nitrogen environment, be cooled to room temperature；
(3) product in step 2 being regulated pH is 7, adds tristerin 5-8 part, stirs, ultrasonic, obtains
Composite polyethylene material.
Stir speed (S.S.) in described step 3 is 320 revs/min.
Ultrasonic time in described step 3 is 30-50 minute.
Compared with prior art, beneficial effects of the present invention:
Electrical insulating property that the composite polyethylene material of the present invention is good owing to the addition of polyformaldehyde and polyvinyl alcohol has, power
Learn intensity, impact resistance and cold tolerance, can be by being blow molded, being molded and prolong the technological formings such as pressure, after making film article, its table
Face good luster, overcomes the low-temperature flexibility of original polythene material and the problem that fragility is bigger, prepared composite polyethylene material
There is high-modulus, counter-bending and stress cracking resistance, the impact strength advantage such as preferably under low temperature.The present invention is obtained by optimization
When the mass ratio that Low Density Polyethylene, high density polyethylene (HDPE) and linear low density polyethylene put into is 5:1:1, material has high property
Can ratio, the advantages such as appearance transparent, relaxation shrinkage that anti-buffer intensity is high, good, resistance to scraping, anti-tear performance be good simultaneously.
