摘要
PURPOSE: A manufacturing method of modified polyethylene powder is provided not to generate volatile organic compound during coating film formation, to prevent environment contamination, and to secure the safety of a worker. CONSTITUTION: A manufacturing method of modified polyethylene powder comprises: a step(S10) of manufacturing modified resin by reacting and extruding high density polyethylene which has the high flexability of 60-100 melt index, and 0.5-1.5 parts by weight maleic anhydride on the basis of total modified resin(P1); a step(S20) of manufacturing resin composition(P2) by mixing 10-40 parts by weight the modified resin(P1), 30-85 parts by weight adhesive resin, and 5-30 parts by weight flame retardant; and an additional step(S30) of manufacturing powder by pulverizing the resin composition(P2) to the size of 10-300 micron.
