METHOD FOR MANUFACTURING MODIFIED ABS MATERIAL, METHOD FOR MANUFACTURING CAMBERED REAR SHELL, AND REAR SHELL

摘要

Disclosed are a method for manufacturing a modified ABS material, a method for manufacturing a cambered rear shell of a display terminal, and the cambered rear shell of the display terminal. The method for manufacturing a modified ABS material comprises: a common ABS material, talcum powder, a lubricating agent and an antioxidant are added into a plastic extruder, wherein the lubricating agent comprises a silicon-magnesium composite lubricating agent and a stearic acid lubricating agent, the antioxidant comprises a phosphorus phenolic composite antioxidant, and the weight percentage of the common ABS material is 96 percent to 98 percent, the weight percentage of the talcum powder is 1 percent to 2 percent, the weight percentage of the silicon-magnesium composite lubricating agent is 0.5 percent to 2 percent, the weight percentage of the stearic acid lubricating agent is 0.2 percent to 1 percent, and the weight percentage of the phosphorus phenolic composite antioxidant is 0.3 percent to 1 percent; and the temperature of the plastic extruder is adjusted to 180°C to 230°C, and the modified ABS material is extruded.
