Antioxidant, high flow, halogen-free and flame retardant ABS and preparation process thereof

The invention provides an antioxidant, high flow, halogen-free and flame retardant ABS (acrylonitrile-butadiene-styrene copolymer) and a preparation process thereof. The ABS is composed of the following components by weight: 60-80 parts of ABS; 10-20 parts of a compound flame retardant; 10-20 parts of a toughening agent; 0-5 parts of a flow modifier; 0-1 part of a light stabilizer; 0.1-1 part of an antioxidant; and 0-5 parts of other processing aids. The innovation point of the material lies in that the compound flame retardant, the light stabilizer, the antioxidant and the flow modifier are introduced to achieve a good flame retardant effect and also ensure the ABS good mechanical properties, weather resistance, and processing fluidity. The antioxidant, high flow, halogen-free and flame retardant ABS prepared by the invention has the characteristics of ageing resistance, high flow, low cost, high mechanical properties and stable flame retardancy, and can be widely used in the field of ultra-thin walls and large parts, like office equipment, communication, movie and television multimedia, etc.
