Method for manufacturing exterior parts of copying machine or printer using halogen-free flame-retardant resin composition containing recycled polycarbonate and recycled polyethylene terephthalate

摘要

A copier/printer exterior part uses a halogen-free flame-retardant resin composition. The halogen-free flame-retardant resin composition includes 5 wt% to 50 wt% of unused polycarbonate, 20 wt% to 63 wt% of recycled polycarbonate, 5 wt% to 35 wt% of recycled polyethylene terephthalate, 0.2 wt% to 2 wt% of a styrene-acrylonitrile-glycidyl methacrylate terpolymer, 5 wt% to 15 wt% of a toughener, 10 wt% to 20 wt% of a flame retardant, 0.1 wt% to 0.8 wt% of a flame-retardant antidrip agent, 0.1 wt% to 1 wt% of an antioxidant, and 0.1 wt% to 2 wt% of a lubricant. The styrene-acrylonitrile-glycidyl methacrylate terpolymer includes 1 wt% to 5 wt% of glycidyl methacrylate and 20 wt% to 33 wt% of acrylonitrile.
