| 中文摘要: |
| 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UL94 V-O级（1.6 mm）；（JFMCAiMVQ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。 |
| 英文摘要: |
| 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. |
