TLDR
In this article, the effect of flame-retardant additives such as tributyl phosphate, tri(dibromopropyl) phosphate, aluminum hydroxide powder and aluminium hydroxides gel are used for acrylic fiber (acrylonitrile and vinyl acetate copolymer).Abstract:
In this study, flame-retardant additives such as tributyl phosphate, tri(dibromopropyl) phosphate, aluminium hydroxide powder and aluminium hydroxide gel are used for acrylic fibre (acrylonitrile and vinyl acetate copolymer), and calcium phosphate and antimony oxide are introduced into modacrylic fibre (acrylonitrile and vinylidene chloride copolymer). Investigations are carried out on the effect of these flame-retardants on the thermal properties, mechanical properties, morphology and flammability of acrylic and modacrylic fibres. The results show that the effect of additives on the rate of coagulation during spinning can be understood from the changee of morphology of the fibres. Tri(dibromopropyl) phosphate and antimony oxide are good flame-retardant and good synergistic flame retardant, respectively.read more
