SYNTHESIS AND APPLICATION OF FLAME RETARDANT AS UV FIXING AGENT

摘要

PURPOSE: A flame retardant composition containing a phosphonate compound and a method for flame retardant fiber treatment by UV curing are provided to prevent fiber damage and maintain form stability. CONSTITUTION: A phosphonate compound having an effect of flame retardant is denoted by chemical formula 1. In chemical formula 1, R1 and R2 are same or different hydrogen or alkyl group of C1-C3. A flame retardant composition contains 100 weight parts of compound of chemical formula 1, 1-10 weight parts of photo initiator, and 1-10 weight parts of solubilizer. The photoinitiator is benzophenone, aceophenone, or ether compound. A method for flame retardant treatment of fiber comprises: a step of immersing the fiber sample in a flame retardant composition an padding; a step of irradiating UV to the fiber sample to cure the flame retardant composition on the surface of the fiber sample; and a step of washing and drying the cured fiber sample.
