POLYESTER CHIP FOR WHITE CONDUCTIVE FIBER AND PREPARATION METHOD THEREOF

摘要

The present invention provides a method for producing a polyester master batch containing a functional material produced through an extruder divided into a first section, a second section, a third section, a fourth section and a fifth section, The polyester masterbatch is introduced and passed at a passage time of 8 to 15 seconds while heating at 100 to 150 DEG C while passing through the second section at a passage time of 3 to 6 seconds while being heated to 150 to 200 DEG C to melt the polyester step; The silicon carbide (SiC) is introduced into the third section, and the silicon carbide is passed through at a passage time of 2 to 4 seconds while being heated to 200 to 240 캜; Zinc oxide (ZnO) is injected in the fourth section and passes through at a passage time of 1 to 3 seconds while heating at 240 to 270 ° C; And an extrusion step of extruding a polyester containing silicon carbide and zinc oxide as functional materials while heating to 270 to 290 ° C in the fifth section, and a polyester masterbatch containing the functional material / RTI
