二(2,3—二溴丙基)烯丙基异三聚氰酸酯对丙烯酸系树脂的阻燃研究

Study on the Flame-retardance of Cured Acrylic Resin Retarded by Bis(2,3-dibromopropyl) allyisocyanurate

用氧指数(LOI)、热失重(TGA)、微分热失重(DTG)等方法研究了二(2,3—二溴丙基)烯丙基异三聚氰酸酯对丙烯酸系树脂阻燃性的影响。结果表明二(2,3—二溴丙基)烯丙基异三聚氰酸酯对丙烯酸系树脂有一定的阻燃作用,与三氧化二锑配用时具有阻燃协同效应,阻燃效果较好,与磷酸三甲苯酯配用时没有协同效果。

In this paper, The flame-retardation and mechanism of Bis(2,3-dibromopropyl) allyisocyanurate (DBAC) toward cured acrylic resin were studied by the measurment of limit oxygen index (LOI) and thermogravimetry analysis (TGA) .The results indicate that DBAC can flame- retard the acrylic resin to some extent. There is synergism between DBAC and antimony trioxide (Sb2O3). But the synergism between DBAC and tricresyl phosphate (TCP) don抰 exsist.
