Abstract
The invention provides antistatic polyethylene. The antistatic polyethylene is characterized by comprising the following components in part by weight: 80 to 90 parts of polyethylene, 10 to 20 parts of ethylene-acrylic acid copolymer, 0.2 to 1.0 part of zinc stearate, 0.1 to 0.5 part of zinc acetate and 0.1 to 0.4 part of polyethylene wax. In the method, the antistatic material is made of polyethylene and a macromolecular material, wherein the macromolecular material is manufactured by extruding and granulating a mixture of the ethylene-acrylic acid copolymer, the zinc stearate and the zinc acetate with a twin-screw rod at the temperature of between 150 and 200 DEG C. Because the macromolecular material is crosslinked by ionic bonds, the conductivity of the antistatic polyethylene is quite good, and the miscibility of the macromolecular material and the polyethylene is good, no precipitation phenomenon occurs, and the antistatic polyethylene can be made into various colorful products.
Description
Technical field
The present invention relates to electric wire and cable material and make field, specifically a kind of anti-static polyethylene and preparation method thereof.
Background technology
Polyethylene has good physical and mechanical properties, electrical property and chemical stability, and good processability can be at 80-110 ℃ of following life-time service, can be made into sheet material, tubing, film, fiber and the container that differs in size etc.Be widely used in industry, agricultural, medical and health and articles for daily use industry.
Because poly electrical insulation capability excellence, therefore sheet material, tubing, the film with polyethylene production has static, greatly influenced the application of polyethylene in electron trade, and for this reason, people have released anti-static polyethylene material.
Anti-static polyethylene material in the past is divided into two kinds: one, add static inhibitor, two, add graphitized carbon black, three, add various conductive metal powder.
More than three kinds of methods all have easy to processly, need not do the change of big technical recipe, but have the inherent shortcoming yet:
One, adds static inhibitor.
Static inhibitor all is made up of some low molecular organic compound, after joining polyethylene formation, precipitate into product surface and form anti-static polyethylene, reach antistatic effect, so the antistatic effect of its product surface and inside is inequality, secondly, static inhibitor is volatile, the work-ing life of video product, the 3rd, because static inhibitor is a small organic molecule, the valency amount is many can to cause goods " bloom " phenomenon, and influence is used.
Two, add graphitized carbon black.
Graphitized carbon black is a kind of carbon black of resistor base, after the adding polyethylene is made product, does not add three big disadvantages of static inhibitor goods fully, but can only be used to produce the black goods.
Three, add various conductive metal powder.
Add various conductive metal powder, make physical and mechanical properties, the process industrial art performance variation of goods, proportion increases, and price is expensive, has therefore also influenced its range of application.
Summary of the invention
The object of the invention provides a kind of anti-static polyethylene and preparation method thereof, adopts polyethylene to add macromolecular material and makes antistatic material.
Technical scheme of the present invention is:

A kind of anti-static polyethylene, this product comprises polyethylene, ethylene-acrylic acid copolymer, Zinic stearas, zinc acetate and polyethylene wax, described polyethylene is the 80-90 weight part, and ethylene-acrylic acid copolymer is that 10-20 weight part, Zinic stearas are that 0.2-1.0 weight part, zinc acetate are 0.1-0.5 weight part, polyethylene wax 0.1-0.4 weight part.In polyethylene, ethylene-acrylic acid copolymer, Zinic stearas, zinc acetate and polyethylene wax is 100%.Acrylic acid content is 5-15% in the described ethylene-acrylic acid copolymer.
A kind of preparation method of anti-static polyethylene may further comprise the steps:
A) with the polyethylene wax high-speed stirring of the zinc acetate of the Zinic stearas of the ethylene-acrylic acid copolymer of 10-20 weight part, 0.2-1.0 weight part, 0.1-0.5 weight part, 0.1-0.4 weight part 5-6 minute to 80 ℃;
B) the material extruding pelletization that step a) is obtained obtains the macromolecular material of a kind of molecular weight between 25000-26000;
C) macromolecular material that step b) is obtained with obtain anti-static polyethylene after the polyethylene of 80-90 weight part mixes.
Among the described step b, the material that step a) is obtained adds extruding pelletization in the twin screw extruder.
Among the described step b, material extruding pelletization under 150-200 ℃ of condition that step a) is obtained.
The invention has the beneficial effects as follows:
The present invention adopts polyethylene to add macromolecular material and makes antistatic material, this macromolecular material material by ethylene-acrylic acid copolymer add stearic acid zinc, zinc acetate forms through double-screw extruding pelletizing at 150-200 ℃.Because macromolecular material is by ionic crosslinking, so electroconductibility is very good, and macromolecular material and polyethylene compatibility are good, can " not separate out ", can make various colored articles.
The conductivity index assert by the volume resistance rate score of material, under 20 ℃, and the volume specific resistance such as the table 1 of different anti-static polyethylenes:
Under the table 1.20 ℃, the volume specific resistance of different anti-static polyethylenes (Ω M) synopsis.
| The modification anti-static polyethylene | Add the polyethylene of graphitized carbon black | Add the polyethylene of static inhibitor |
| 4.2*10 5 | 3.5*10 4 | 1.2*10 6 |
The resistivity of anti-static plastic should be 1.0*10
4-1.0*10
7Between the Ω M, therefore, anti-static polyethylene of the present invention adopts polyethylene, and promptly the electroconductibility of modification anti-static polyethylene is better than the polyethylene that adds static inhibitor, leads a carbon black and be worse than to add.
Compatibility is to judge according to the tensile strength of material, and intensity greatly then compatibility is better.The tensile strength such as the table 2 of different anti-static polyethylenes:
The tensile strength of the different anti-static polyethylenes of table 2. (MPa) synopsis.
| The modification anti-static polyethylene | Add the polyethylene of graphitized carbon black | Add the polyethylene of static inhibitor |
| 17.4 | 14.6 | 17.5 |
Anti-static polyethylene of the present invention adopts polyethylene, and promptly the tensile strength of modification anti-static polyethylene is roughly the same greater than the polythene material of polyethylene that adds graphitized carbon black and interpolation static inhibitor.
To sum up, anti-static polyethylene of the present invention adopts polyethylene to have comparatively equilibrated physical and mechanical properties, combine polyethylene that adds graphitized carbon black and the poly advantage of adding static inhibitor, can satisfy the requirement of cable industry well insulating material electroconductibility and compatibility.
