ABS Automobile interiors manufactured from compounding compositions combining ABS and foaming agent

摘要

The present invention relates to a manufacturing method for a compounding composition in which acrylonitrile butadiene styrene (ABS) for manufacturing foam ABS copolymer and a foaming agent are combined. The manufacturing method for a compounding composition includes: a first mixing and drying process of inserting 10-50 parts by weight of styrene-acrylonitrile (SAN) and 50-90 parts by weight of the ABS copolymer into a mixer and mixing and drying the same at the temperature of 100°C; a second mixing process of mixing 0.1-10% of the foaming agent (azodicarbonamide (AZC) or toluene sulfonyl hydrazide (TSH)), 0.01-5% of a coloring admixture (pigment + ethylene-vinyl acetate (EVA)), 0.2-1% of antioxidant, 0.1-2% of an ultraviolet ray absorbent, and 0.01-0.2% of a dispersant into a mixed resin in the mixer dried by the first mixing and drying process; a mixed resin discharging and hopper supplying process; and a foaming and extrusion-molding process. According to the present invention, the manufacturing method for a compounding composition in which ABS for manufacturing foam ABS copolymer and a foaming agent are combined can reduce production costs by reducing the product′s weight and production cycle.
