【摘要】 通过十溴二苯醚与三氧化二锑协调使用制备阻燃环氧树脂,选择粒径为2~30μm和60~120μm的空心玻璃微珠按照体积比为1∶1均匀混合,固化剂十二烯基琥珀酸酐与甲基四氢邻苯二甲酸酐复配制备了4 500m阻燃固体浮力材料,材料的密度、耐静水压强度与普通4 500m浮力材料相当,并且材料氧指数达27%~29%。更多还原

【Abstract】 With the flame retardant epoxy resin prepared through decabromodiphenyl oxide and antimony oxide,two kinds of hollow glass microspheres with the respective particle sizes of 2 ~ 30μm and 60 ~ 120μm mixed with volume ratio of 1 ∶ 1 and dodecenylsuccinic anhydride and methyl tetrahydrophthalic anhydride as the compound curing agent,the flame retardant solid buoyancy material of 4 500 meters was prepared.The density and hydrostatic pressure strength of the material was the same as the ordinary 4 500 meters of solid buoyancy material,and the oxygen index of the material was 27% ~ 29%.更多还原
