Dustproof, antibacterial and ageing-resistant color master batch of polyethylene (PE) plastic slide, and preparation method of color master batch

Abstract

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 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.

Description

technical field [0001] The invention relates to the technical field of plastic coloring, in particular to a dustproof, antibacterial, antiaging and antiaging multifunctional color masterbatch for polyethylene plastic slides and a preparation method. Background technique [0002] Polyethylene is the most widely used variety of general-purpose plastics. It is widely used in packaging materials, daily necessities, office supplies, medical supplies, gas transmission, water supply, sewage, agricultural irrigation, oil fields, chemicals, mines, post and telecommunications and other fields. Polyethylene has good heat resistance, cold resistance and chemical stability, high rigidity, toughness and mechanical strength, does not absorb moisture and has good water vapor performance, non-toxic, easy to form and process, especially its rich raw materials Source, cheap material price and become the material of choice for plastic slides. [0003] Plastic slides are large-scale public amus...

AI Technical Summary

Problems solved by technology

The method of adding a single masterbatch makes it necessary to use a large amount of carrier resin and dispersing lubricant when the comprehensive performance of polyethylene is high, and this leads to high energy consumption and high antioxidant consumption during processing, and downstream molding There are many components to be processed, and the process is complicated, etc.
