Article Preview

As the epoxy potting compound widely used, their flame retardant properties were concerned day by day.This paper neopentyl glycol phosphate melamine salt (NPM) was synthesised via phosphorus oxychloride as the acid source, neopentyl glycol as carbon source, melamine as gas source. The structure of NPM was characterized via infrared spectroscopic analysis (IR). Then the flame retardant properties of NPM/epoxy resin systerm were researched via the limiting oxygen index (LOI), vertical burning experiment, thermal gravimetric analysis (TGA) . The result shows that When the dosage of NPM is 27%, limiting oxygen index of epoxy resin have a extremum, is 32.4, char yield is 18.7% at 600°C. NPM can play a significant role in the improvement of the flame retardant properties of the epoxy.
