Abstract

The invention relates to the technical field of high polymer materials, in particular to ABS noctilucent masterbatches and a preparation method thereof. The ABS noctilucent masterbatches comprise the following components in percentage by mass: 50 to 75 percent of ABS, 5 to 10 percent of dispersant, and 20 to 40 percent of noctilucent powder, wherein the dispersant is dimethyl silicon oil and / or polyethylene wax. The ABS noctilucent masterbatches and the preparation method thereof have the benefits that the abrasion of a machine caused by noctilucent powder during a production process is reduced and the blackening phenomenon of noctilucent powder is avoided by the improvements, such as extruding through a single screw, reducing extruding rate, raising processing temperature, mixing materials in a plastic material barrel at a low speed, of process conditions; the processing temperature is risen, the coating capacity of melt to the noctilucent powder is improved, and the ABS noctilucent masterbatches with higher concentration are prepared by mixing ABS powdery matrix resin and ABS particular matrix resin; the interference to the luminance caused by the color of the matrix resin is reduced by using a suitable amount of dispersant; the ABS noctilucent masterbatches prepared by the preparation method has the advantages of high concentration, long-acting luminescence, large molecular weight of ABS, low abrasion to the machine, uniform dispersion, no chromatic aberration, wide application range and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an ABS luminous masterbatch and a preparation method thereof. Background technique [0002] ABS resin is an acrylonitrile-butadiene-styrene copolymer. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the advantages of easy processing, stable product size and good surface gloss. It is a thermoplastic engineering plastic with a wide range of uses. [0003] In recent years, with the development of functional masterbatch technology, luminous masterbatch has also developed rapidly. However, the existing luminous masterbatches are limited in use due to many defects. At present, the concentration of commercially available ABS luminous masterbatch is generally low, because the existing ABS luminous masterbatch production process usually adopts twin-screw extrusion, the twin-screw torque...
