Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of polyethylene antistatic master granule and preparation method thereof.
Background technology
Polyethylene (PE) has light weight, the feature that nontoxic, forming process is easy, the ratio of performance to price is high, is all widely used in a lot of fields, and be that consumption occupies deputy general-purpose plastics in the world.Because polyethylene belongs to electrically insulating material, its surface easily produces static, brings potential safety hazard to actual production.Poly eliminostatic adds type and the large class of outer spreading type two in can being divided into by employing method difference, wherein, add with interior that type is antistatic to be most widely used.But because the fusing point of most of static inhibitor is lower than polyvinyl resin, there is strong outer lubrication, if direct interpolation can cause processing difficulties in the time of forming process, so, conventionally join in polyvinyl resin and be advisable with antistatic master granule form.
Summary of the invention
The object of the present invention is to provide a kind of consistency good, be uniformly dispersed, thermotolerance is high, stable performance, cost are low and have polyethylene antistatic master granule of permanent antistatic performance and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: polyethylene antistatic master granule, its component by mass percent proportioning is: polyvinyl resin 20%～80%, static inhibitor 15%～40%, nucleator 0.5%～2%, dispersion agent 3%～5%, coupling agent 0.5%～3%, other additive 0～1%.
Described static inhibitor is the one in two (2-hydroxyethyl) octyl group methyl biconjugate ammonium tosylates, quaternary ammonium compound, alkylsulfonate, stearic acid monoglycerides (GMS), polyether ester, Nanometer-sized Antimony-doped stannic oxide (ATO).
Described nucleator is talcum powder.
Described dispersion agent is the one in polyethylene wax, oxidized polyethlene wax (EVA wax), OP wax, ethylene bis stearic acid amide (EBS).
Described coupling agent is silane coupling agent or titanate coupling agent.
Other described additive is oxidation inhibitor and colorant.
The preparation method of above-mentioned polyethylene antistatic master granule is: each component is prepared burden by weight proportion, then add in high-speed mixer or ultrasonic generator and mix 10～30 minutes, again the material mixing is added to twin screw extruder melt blending, melt temperature is controlled at 150 ℃～180 ℃, after extruding by twin screw extruder, through overcooling, pelletizing, dry, pack and obtain polyethylene antistatic master granule of the present invention.
The invention has the beneficial effects as follows, the antistatic master granule that the present invention makes is applied to polyethylene and carries out antistatic modifiedly, can make surface resistivity be reduced to 10
8～10
10between Ω cm, antistatic effect is good and lasting, and its processing characteristics is good, Heat stability is good, and cost is low, easy to use.
