Antioxidants are important additives to improve the thermal stability of plastics, however, the addition of antioxidants affects the processing and mechanical properties of ABS plastic. This study aims to prepare an antioxidant emulsion for ABS plastic and investigate its addition amount and effects on processing and mechanical properties. Firstly, common antioxidants are selected as raw materials. Antioxidant emulsions are prepared by emulsifying agents and characterized. Then, the antioxidant emulsion is added to ABS plastic, and the effects of different amounts of antioxidant emulsion on the processing and mechanical properties of ABS plastic are studied through experiments. Finally, the ABS plastic modified by the antioxidant emulsion is coagulated by a and its perance is tested. The results of this study show that the antioxidant emulsion can effectively improve the thermal stability of ABS plastic and extend its service life, but its addition amount should be moderate, otherwise it will have adverse effects on the processing and mechanical properties of ABS plastic. Through the optimization of coagulation process, ABS plastic modified by antioxidant emulsion with good perance can be obtained.
