Study on flame retardant ABS

Abstract

Flame-retardant ABS resin was prepared by adding fl ame retardant, toughening agent and dispersing silicone oil with acrylonitrile-butadiene-styrene resin (ABS, grade 0215 A) as raw material. The results showed that in the ABS resin, fl ame retardant with tetrabromobisphenol A and antimony trioxide as the composite system (the mass ratio of 2:1) was added. When the bromine content of the system was more than 10%, the flame retardant ABS meets the requirements of UL 94 V-0. The best toughening agent for flame retardant ABS resin is ABS graft powder. When the amount of fl ame retardant ABS is 9% ~ 19% (mass fraction) Strength of 150-200 J / m; in the same formula and operating conditions, brominated alkylene oxide as fl ame retardant prepared fl ame retardant ABS resin, the weather resistance is better than tetrabromobisphenol A as fl ame retardant The Composite expansion fl ame retardant and coated red phosphorus is an eff ective halogen-free fl ame retardant.
