9. the preparation method of the fibre-added fire-retardant polyethylene powders of the toughness reinforcing enhancing of a kind of micro-calcium carbonate according to claim 1, is characterized in that, comprises the following steps:
(1) take by weight ratio poly-2,6-dibromo phenylene ether (PBO) 50wt%, melamine polyphosphates (MPP) 25wt% and talcum powder 25wt%, make to mix, and makes compound flame redundant, then at 80 ℃～85 ℃, be dried 30～45 minutes, stand-by;
(2) after micro-calcium carbonate and surface treatment agent are taken by weight ratio, add in sonic oscillation producer or high-speed mixer, at 100 ℃～120 ℃ temperature, stir 20～60 minutes, make dispersedly, be then cooled to lower than 40 ℃ of dischargings, stand-by;
(3) take by weight ratio polyethylene, compound flame redundant, oxidation inhibitor, lubricant and other additives, add high-speed mixer, add the material of step (2) simultaneously, make fully to mix together 5～10 minutes;
(4) again by the main spout of the compound input twin screw extruder of step (3), the glass fibre of processing through silane coupling agent taking is by weight ratio added from the side spout of twin screw extruder, control screw speed at 180～600 revs/min, barrel zone temperature is at 180 ℃～250 ℃, by the shearing of twin screw extruder, mixing, extrude again, cooling, pelletizing, dry, then be broken into fine powder and sieve by plastic crusher, get the fibre-added fire-retardant polyethylene powders that 180～200 objects form and obtain the toughness reinforcing enhancing of a kind of micro-calcium carbonate of the present invention.
