In this paper, bromized polystyrene flame retardant was synthesized by electrophilic substitution of waste polystrene with bromine using aluminium ehlorid as catalyst.
The paper introduced the synthetic process of the flame retardant and lubricant Melamine Cyanurate Acid(MCA),which was prepared by Melamine and Cyanurate Acid.
Flame retardant vinyl ester resin using tetrabromo bisphenol A, epichlorohydrin, acrylic acid as raw materials was also synthesized, Its flame retardant property was excellent.
Synthetic method of phosphoretted fire retarding agent - YHD was researched.The property and application technique together with its application result of flame retardant YHD were mentioned here.
