as a kind of environment-friendly material has gained a great attention. If the flame retardant of PLA is improved
the scope of application can be further expended. The way for its modification is mainly focused on using additive type flame retardant agents including phosphorus flame retardants
nitrogenated flame retardants
silicone flame retardants
metal compounds and their combinational systems. And
reacting flame-retardants for PLA are constantly in development too. This review presents the main flame retardant mechanism and particularly focus on the development of the flame retardant of PLA. And the research direction in the future was prospected.
