摘要: 本文以羟乙基甲基丙烯酸酯磷酸酯(HEMAP)作为不饱和树脂的反应型含磷阻燃剂,研究其对不饱和树脂阻燃性能的影响。当不饱和树脂加入5份HEMAP后,固化物的极限氧指数为32.5。热重分析结果表明,当不饱和树脂加入HEMAP量从0增加到20份时,氮气下10%失重温度和最大分解温度明显降低,P-O-C键的提前分解产生磷酸类物质,有效阻止了不饱和树脂的进一步分解,800℃残炭率从3.8%提高到31.4%;空气下500℃下初级残炭率从20.6%提高到46.3%。用动态热机械分析仪测试了树脂浇铸体损耗因子,得到树脂体系的玻璃化转变温度,加入5份HEMAP后树脂体系的Tg从120.9℃提高到122℃。

Abstract: A reactive phosphorus-containing fire retardant, 2-hydroxyethyl methacrylate phosphate (HEMAP), was added to the unsaturated resin to improve its flame retardant properties. The cured unsaturated resin reached limiting oxygen index of 32.5 as added 5 parts of HEMAP. Thermal properties of unsaturated resin were studied by means of TG and DTG. Decomposition temperature of 10% mass loss and maximum weight loss both dropped with the increase of HEMAP from 0 to 20 parts by weight. However, formation of phosphorus-containing acid from decomposition of P-O-C bonds inhibited effectively further decomposition of the unsaturated resin. As the HEMAP content increased, the char yield increased from 3.8% to 31.4% at 800℃ in N2 atmospheres, and the carbonaceous char yield increased from 0 to 4 at 500℃ in air atmosphere. The glass transition temperature (Tg) was measured by dynamic mechanical thermal analysis (DMA). The Tg of different unsaturated resins increased from 120.9℃ to 122℃ after added 5 parts of HEMAP.
