Abstract

The invention discloses a preparation method for polypropylene coloring masterbatches, and belongs to the technical field of plastic additives. The method comprises the following steps of A, mixing: adding 25 to 40 parts by weight of a polypropylene random copolymer and 10 to 20 parts by weight of a dispersant into a high-speed mixer, performing pre-mixing for 3 to 6min, adding 10 to 18 parts by weight of nanometer montmorillonite, 3 to 8 parts by weight of a pigment, 2 to 5 parts by weight of an antibacterial agent, 2 to 5 parts by weight of a light stabilizer, 0.1 to 0.8 part by weight of cerium oxide and 2 to 8 parts by weight of an enhanced improver, continually performing mixing for 20 to 35min, and performing discharging, wherein the enhanced improver is nanometer silicon; B, extruding; C, granulating and packaging. The prepared coloring masterbatches have the advantages of high resistance to high temperature, high processability and capability of endowing a product with long service life and wide application range.
