Abstract

Abstract: A novel flame rctardant 1，3，5一tri(5，5-dimcthyl-1,3-dioxacyclophosphorinane phosphonatc) benzene(FR) and APP were introduced into polypropylene, and the combustion properties of the com-
positc were studied using limiting oxygen index(LOI)，UL94 test, and cone calorimeter test. Itshowed that FR with APP improved the LOI values and UL94 combustion properties, prolonged igni-tion time, and reduced the heat release rate and CO, COZ concentration in smoke. The synergistic effects were prominent. The LOI reached 29.6%and UL94 reached V-0 when 15%FR and 10% APP were added to polypropylene.

Key words: polypropylene, phosphorou, 一containing flame retardant, combustion property
