Abstract:

In order to effectively solve the flammable defects of polyacrylonitrile fibers and its fabrics and promote the industrial application of polyacrylonitrile products, the research progress of flame retardant modification of polyacrylonitrile at home and abroad was systematically reviewed. The flame retardant mechanism and five main flame retardant modification methods of polyacrylonitrile were introduced. The characteristics and shortcomings of each method during the preparation of flame retardant polyacrylonitrile fibers were expounded and analyzed. The research status of flame retardant polyacrylonitrile at home and abroad was summarized, and the future research of flame retardant modification of polyacrylonitrile was prospected. It is pointed out that blending, copolymerization and chemical modification are expected to become the main methods of industrialization. With the concept of environmental protection gradually strengthened, the research on green environment-friendliness halogen-free flame retardant fiber is deepened, and the development of halogen-free flame retardant polyacrylonitrile fiber will become the focus of research and industrialization.

Key words: halogen-free flame retardant, polyacrylonitrile, flame retardant modification, flame retardant mechanism
