9. a kind of antistatic high-performance toughening modifying polyethylene powders according to claim 1, is characterized in that, other described additives are photostabilizer and colorant.
10. the preparation method of a kind of antistatic high-performance toughening modifying polyethylene powders according to claim 1, is characterized in that, comprises the following steps:
(1) take by weight ratio poly-2,6-dibromo phenylene ether 50wt%, phospho acid aluminium 25wt% and magnesium hydroxide 25wt%, make to mix, make compound flame redundant, then at 80 DEG C～100 DEG C, be dried 30～45 minutes, stand-by;
(2) after Nano particles of calcium carbonate and surface treatment agent are taken by weight ratio, add sonic oscillation producer or be not less than in the high-speed mixer of 3000 revs/min, at 80 DEG C～110 DEG C temperature, stir 10～60 minutes, make the even coated nano calcium carbonate particle of surface treatment agent, then be cooled to lower than 40 DEG C, discharging is stand-by;
(3) take by weight ratio elastomerics, and even with the mixing of materials of step (2), then add in two roller mills or Banbury mixer, in 120 DEG C～140 DEG C mixing 5～10 minutes, then after pulling-on piece, blank, make core-shell master batch of elastomerics/Nano particles of calcium carbonate;
(4) take by weight ratio polyethylene, compound flame redundant, static inhibitor, oxidation inhibitor, lubricant and other additives, add high-speed mixer, the core-shell master batch that simultaneously adds step (4) to make, makes fully to mix 5～10 minutes;
(5) again the mixture of step (4) is added to twin screw extruder melt blending, melt temperature is controlled at 180 DEG C～240 DEG C, screw speed is 200～500 revs/min, shearing by twin screw extruder, mixing 10～15 minutes, extrude again, cooling, pelletizing, dry, then be broken into fine powder and sieve by plastic crusher, getting 180～200 objects and form and obtain a kind of antistatic high-performance toughening modifying polyethylene powders of the present invention.
