High-performance light-storing noctilucent master batch for polyolefin plastic and preparation method thereof

Abstract

The invention relates to a high-performance light-storing noctilucent master batch for polyolefin plastic and a preparation method thereof. The high-performance noctilucent master batch for polyolefin plastic comprises: 10-15.5% of LLDPE (the melt flow rate is 15-25g / 10min, and the particle size is 30-60 meshes), 27.5-5% of LDPE (the melt flow rate is 5-10g / 10min, an the particle size is 50-100 meshes), 60-75% of one (or multiple) noctilucent pigment, 2.0-3.0% of polyethylene wax (the molecular weight is 3000-4000) and 0.5-1.5% of ethylene bis stearamide. The preparation method comprises the following steps: putting 60% of the noctilucent pigment and the other components into a mixer, uniformly mixing, and performing melt blending through a double screw extruder, wherein the temperature is controlled at 140-180 DEG C; meanwhile, feeding the residual 40% of the noctilucent pigment into a machine barrel of the extruder through lateral charging in a uniform metering manner, and mixing and extruding together with the main materials; then granulating and molding in a brace water-cooling cutting and drawing manner or a mold surface air-cooling cutting and drawing manner; and finally, drying to obtain the master batch provided by the invention. The master batch can be used for coloring of plastic products in plastic processing industry.

Description

technical field [0001] The invention relates to a high-performance light-storing luminous masterbatch for polyolefin plastics and a preparation method thereof, which can be applied to the coloring of plastic products in the plastic processing industry. technical background [0002] At present, the luminous masterbatches provided on the market generally have the following disadvantages: 1. Masterbatches with high luminous powder content in the masterbatch have unsatisfactory dispersion performance, and most of them can only be used for thick-walled plastic products; 2. Good dispersion performance High-quality luminous masterbatches often have a low concentration of luminous powder, and are added in a large proportion in thin-walled plastic products (especially plastic films); 3. The color of the masterbatch tends to darken. Contents of the invention [0003] Aiming at the problems in the prior art, the object of the present invention is to provide a high-performance light-s...
