The invention relates to a dustproof, antibacterial and
ageing-resistant multifunctional color master batch of a
polyethylene (PE) plastic slide. The dustproof, antibacterial and
ageing-resistant multifunctional color master batch of the PE plastic slide comprises the following components in percentage by weight: 12.5 to 17.5 percent of dust preventive, 15.0 to 20.0 percent of
antibacterial agent, 5.0 to 10.0 percent of anti-
ageing agent, 17.5 to 22.5 percent of coloring agent, 7.5 to 12.5 percent of dispersing
lubricant, 0.5 to 2.0 percent of compatilizer and 25.0 to 35.0 percent of carrier resin. A preparation method of the color master batch comprises the following steps of: adding the dust preventive, the
antibacterial agent, the anti-ageing agent, the coloring agent, the dispersing
lubricant and the carrier resin into a high-speed mixer and mixing for 10 to 20 minutes; adding the dust preventive and the compatilizer and stirring for 5 to 10 minutes; adding the
mixed materials into a double-screw extruder and extruding at 140 to 150 DEG C; and cooling,
drying, dicing and packaging to prepare the required master batch. The dustproof, antibacterial and ageing-resistant multifunctional color master batch can eliminate environmental
pollution caused by dust in a downstream PE plastic forming process and realizes environment-friendly and clean production of the PE plastic. The dustproof, antibacterial and ageing-resistant multifunctional color master batch has the characteristics of small using amount of the carrier resin and the dispersing
lubricant and low master batching forming energy and
antioxidant consumption, and can be widely applied to coloring of the PE plastic.
