Abstract

The present invention belongs to the field of plastic preparation, and particularly relates to an ABS material with marble imitation decorative effect and a preparation method thereof. The technical problem to be solved is that the ABS plastic material with marble imitation decorative effect has low impact resistance, insufficient weather resistance and poor wear resistance. The invention solves the above technical problem by providing the ABS material with marble imitation decorative effect. The ABS material comprises the following raw materials by weight: 5-23 parts of filler resin, 60-85 parts of ABS resin, 2-10 parts of a compatibilizer, 5-16 parts of a flow modifier and 2-6 parts of masterbatch. The present invention also provides a preparation method of the above-mentioned ABS material with marble imitation decorative effect. The ABS material with marble imitation decorative effect has the advantages of good color and texture, high gloss, high surface hardness and certain scratch resistance, and can meet the decorative appearance requirements for automotive, household appliances and other products.

Description

technical field [0001] The invention belongs to the field of plastic preparation, and in particular relates to an ABS material with a decorative effect of imitating marble and a preparation method thereof. Background technique [0002] Imitation marble effect decorative materials are widely used in the fields of construction, automobiles, and household appliances. The traditional marble-like decorative effects are mostly achieved by extrusion coating, transfer printing, etc., and the materials that are blended and injection-molded by an extruder to imitate marble decorative effects are mostly achieved by adding speckled pigments or adding natural marble particles. preparation. [0003] The patent "A modified PC / ABS with marble stripe appearance and its preparation method" (CN201210275095.9) discloses a modified PC / ABS with marble stripe appearance. The material is directly injection molded mainly by adding color masterbatch. The masterbatch dispersion presents different te...
