The invention discloses a polyethylene talcum powder master batch. The polyethylene talcum powder master batch is prepared from, by weight, 19.5-20.5% of polyethylene, 0.1-1.1% of polyethylene wax and 78.9-79.9% of talcum powder. During preparation, talcum powder is put at first, polyethylene is added, then, the polyethylene wax is added, the mixture is subjected to smelting to be heated to 150 min, heating is performed for 12 min, then, the mixture enters a double-screw extruder to be mixed, mixing is performed, and then extruding, cooling and grain dicing are performed. In this way, the polyethylene talcum powder master batch is applicable to plastic modification, and due to the compact form and the higher compound quantity, the plastic is good in dispersity, resistant to wear and scraping, capable of achieving feeding easily and good in heat stability.
