| Abstract: |
| Using lab-synthesized highly dispersible melamine cyanurate （GFMCA） as a flame retardant，the MVQ retardant materials were prepared， and the morphology and aggregation state of GFMCA，the flame retardant property and physical property of the MVQ compound were investigated. The results showed that， GFMCA possessed loose aggregation structure， showed outstanding dispersity and stability in MVQ， and had no blooming. The flame retardant properties of traditional melamine cyanurate （MCA）/MVQ and GFMCA/MVQ vulcanizates were similar，and when the addition level of flame retandant was 30 phr， both vulcanizates could achieve UL94 V-O（1.6 mm）. The physical property of GFMCA/MVQ vulcanizates was better. The tensile strength and elongation at break of GFMCA/MVQ vulcanizates were higher than MCA/MVQ vulcanizates by 20% and 118% ，respectively. Overall， GFMCA/MVQ vulcanizates showed better comprehensive performance. |
