Abstract

The invention provides an ABS composite with a special odor, which is prepared from the following raw materials in percentage by mass: 86%-97.4% of ABS resin, 0.4%-4% of antioxidant, 0-5% of flexibilizer, 0.2%-4% of ultraviolet absorber, and 2%-10% of odor regulating master batch, wherein the odor regulating master batch is ABS granules loaded with 0.01%-2% of odor regulator in percentage by mass;and the odor regulator is a mixture of an alcohol, a ketone, an ester and a phenol each having a boiling point of 90-190 DEG C. The composite provided in the present invention is simple in preparation process and low in cost, and further excellent in mechanical properties and capable of well improving the original irritating odor of the ABS composite.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and relates to an ABS composite material, in particular to an ABS composite material with a special odor prepared by using an odor-regulating masterbatch and a preparation method thereof. Background technique [0002] ABS material is a graft copolymer of three monomers of acrylonitrile, 1,3-butadiene and styrene. ABS has excellent mechanical properties, its impact strength is excellent, and can be used at extremely low temperatures; ABS has oil resistance, excellent wear resistance, good dimensional stability, good electrical insulation, and is hardly affected by temperature and humidity and frequency; therefore, ABS materials are widely used in the automotive field, including automotive dashboards, body panels, interior trim panels, steering wheels, sound insulation panels, door locks, bumpers, ventilation pipes and many other components. [0003] Under the trend of "replacing steel with...
