Abstract:The nanosheetAl(OH)3/Mg(OH)2 composite retardant coated with oleic acid is synthesized through chemical compounding technique. The SEM result indicates that through changing the ratio of aluminum and magnesium can different morphology nanosheet composite retardant be prepared. The XRD result indicates that composite retardant is based on Al(OH)3, whose surface is coated with Mg(OH)2. The IR result indicates that composite retardant is coated with oleic acid by way of carboxylic acid salt. The EDS and TG result indicates that oleic acid is coated well-distributed, while Al(OH)3 and Mg(OH)2 are compounded near the ratio of reactant. The thermal analysis (TG and DTA) result indicates that compared with Al(OH)3, Mg(OH)2, and the physical mixture of Al(OH)3 and Mg(OH)2, flame retardancy of composite retardant is greatly improved.
Keywords:composite flame retardant  aluminum hydroxide  magnesium hydroxide    nanosheet  chemical compound  oleic acid
