Special high-concentration color master batch for ABS resin applied to household appliances and preparation method thereof

Abstract

The invention belongs to the technical field of color master batch preparation, and particularly relates to a special high-concentration color master batch for ABS resin applied to household applianceand a preparation method thereof. The preparation method comprises the following steps: 1, feeding; 2, mixing: feeding the raw materials in the step 1 into a mixing cavity of a mixing mill, controlling the temperature of the cavity of the mixing mill to be 40-80 DEG C, and conducting mixing through high-speed shearing with a speed of 520-600 rpm / min; 3, extrusion: sending a molten polymer obtained in step 2 to a twin-screw extruder; and step 4, pelletizing: dehydrating, drying and screening the master batch to obtain a round grain type finished product. Thus, a color master batch product produced by the invention is good in condition, has the advantages of good pigment dispersion and small color difference when used for ABS resin coloring, does not use a compatilizer, is low in cost, simple in process and suitable for large-scale production, and has. relatively good market prospects.

Description

technical field

[0001] The invention relates to the technical field of color masterbatches, in particular to a special high-concentration color masterbatch for home appliance ABS resin and a preparation method thereof. Background technique

[0002] Acrylonitrile-butadiene-styrene copolymer (referred to as ABS resin) is synthesized from three chemical units of acrylonitrile, butadiene and styrene, and its microscopic morphology presents an "islands in the sea" structure. In ABS resin, acrylonitrile provides it with good surface hardness and chemical corrosion resistance; butadiene provides it with toughness and good impact strength; styrene provides it with good processability and dyeability. Therefore, ABS resin has excellent comprehensive performance, good toughness, dimensional stability, low temperature corrosion resistance, etc., and is widely used in the fields of household appliance shells, office supplies, instruments and meters, among which high-end home appliance pl...
