Effect of Magnesium Hydroxide on the Flame Retardant Properties of Unsaturated Polyester Resin
The unsaturated polyester resin containing 35%, 45%, and 55% of magnesium hydroxide were synthesized with 1, 2- propylene glycol, phthalic anhydride, maleic anhydride and styrene as the main materials, and their combustion performance was investigated. Results showed that the ignites times (tig) of...

| Summary: | The unsaturated polyester resin containing 35%, 45%, and 55% of magnesium hydroxide were synthesized with 1, 2- propylene glycol, phthalic anhydride, maleic anhydride and styrene as the main materials, and their combustion performance was investigated. Results showed that the ignites times (tig) of the samples with magnesium hydroxide were higher than samples without magnesium hydroxide. Compared to the samples without magnesium hydroxide, the peak heat release rate (HRRpeak) of the samples contained 35%, 45% and 55% of magnesium hydroxide decreased by 60.47%, 65.89% and 74.99%; total heat release during1200 (THR1200s) reduced by 64.38%, 77.62% and 79.34%; the average specific extinction area (SEAav) decreased by11.96%, 58.15% and 89.15%; the average mass loss rate (MLRav) decreased by 66.12%, 70.25% and 70.25%. The samples with 55% of magnesium hydroxide observed the best flame retardant and smoke suppression effects, and the increase of magnesium hydroxide concentration could significantly improve the flame retardant performance of the unsaturated polyester resin. |
