摘　　要：以自制高分散型三聚氰胺氰尿酸盐(GFMCA)为阻燃剂制备甲基乙烯基硅橡胶(MVQ)阻燃材料,并对阻燃剂粒子形貌及团粒结构、阻燃材料的阻燃性能和物理性能进行研究。结果表明:GFMCA团粒结构松散,在MVQ中表现出优异的分散性和稳定性,无析出。传统三聚氰胺氰尿酸盐(MCA)/MVQ与GFMCA/MVQ硫化胶的阻燃性能相当,当阻燃剂用量为30份时,均可达到UL94V-0级(1.6mm);GFMCA/MVQ硫化胶的物理性能较好,其拉伸强度和拉断伸长率较MCA/MVQ硫化胶分别提高20%和118%。GFMCA/MVQ硫化胶的综合性能较好。Using lab-synthesized highly dispersible melamine cyanurate （GPMt_;A） as a flame re- tardant,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 investiga- ted. 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 addi- tion level of flame retandant was 30 phr, both vulcanizates could achieve UL94 V-0 （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.
