Zusammenfassung: | The invention discloses a good-appearance soft ABS (Acrylonitrile Butadiene Styrene) composition as well as a preparation method and application thereof. The soft ABS composition with good appearance is prepared from the following components in parts by weight: 15 to 30 parts of styrene-acrylonitrile copolymer; 25 to 40 parts of high rubber powder; 1-5 parts of a flow modifier; 25 to 45 parts of styrene elastomer; wherein the content of acrylonitrile in the styrene-acrylonitrile copolymer is 17 to 24.5 weight percent; the flow modifier is a styrene oligomer, and the number-average molecular weight of the flow modifier is not higher than 3000. According to the present invention, the SAN resin with the specific acrylonitrile content is selected, the styrene elastomer is added, and the flow modifier is supplemented, such that the prepared ABS composition has characteristics of low hardness and good appearance.
