ABS ABS METHOD FOR PREPARING ABS RESIN POWDER AND METHOD FOR PREPARING ABS RESIN COMPOSITION IMPROVED SURFACE QUALITY

摘要

The present invention relates to a method of manufacturing an ABS-based resin powder and a method of manufacturing an ABS-based resin composition with improved surface properties, and more specifically, by introducing an acid flocculant into an ABS-based resin latex produced by emulsion polymerization to aggregate. Acid aggregation step; Aging step of aging the acid-agglomerated slurry; A base treatment step of adjusting the pH to 8 to 12 by adding a base to the aged slurry; And dehydrating the base-treated slurry 1 to 3 times, followed by drying to obtain an ABS-based resin powder, wherein the ABS-based resin powder has a residual emulsifier content of 5,000 ppm or less and is acid-free -free) and a method for manufacturing an ABS-based resin powder, and a method for producing an ABS-based resin composition having improved surface properties, including the same.
