一种热稳定性好家电用无卤阻燃绝缘料及其制备方法
摘要：
一种热稳定性好家电用无卤阻燃绝缘料，由下列重量份的原料制成：低密度聚乙烯树脂10-15、乙烯基三甲氧基硅烷0.3-0.4、过氧化二异丙苯0.04-0.08、月桂酸二正丁基锡0.01-0.02、氢氧化镁50-60、EVA60-65、高密度聚乙烯树脂20-23、Mg6Al2(OH)16CO3?4H2O 6-7、氢化松香0.7-0.9、偏苯三酸三(2-乙基己)酯1-1.5、羟基硅油1-2、二氧化锆纳米管2-3。本发明绝缘料使用的二氧化锆纳米管和Mg6Al2(OH)16CO3?4H2O，可以使其颗粒与氢氧化镁搭建出较密的骨架结构,不仅可以使复合材料的阻燃性能达到FV-0级,还可以保证复合材料优良的力学性能，热稳定性得到很大的提高。
摘要（英）：

A high-heat-stability halogen-free flame-retardant insulating material for household appliances comprises, by weight, 10-15 parts of low-density polyethylene resin, 0.3-0.4 part of vinyl tri-methoxysilane, 0.04-0.08 part of dicumyl peroxide, 0.01-0.02 part of dibutyltin dilaurate; 50-60 parts of magnesium hydrate, 60-65 parts of EVA (ethylene-vinyl acetate copolymer), 20-23 parts of high-density polyethylene resin, 6-7 parts of Mg6Al2(OH)16CO3 4H2O, 0.7-0.9 part of hydrogenated rosin, 1-1.5 parts of trioctyl trimellitate, 1-2 parts of hydroxyl silicone oil and 2-3 parts of zirconium dioxide nanotubes. The high-heat-stability halogen-free flame-retardant insulating material has the advantages that by the zirconium dioxide nanotubes and the Mg6Al2(OH)16CO3 4H2O both applied to the insulating material, a dense framework structure can be formed by particles of the insulating material and the magnesium hydrate, so that flame retardation performance of the composite material can reach FV-0 level, excellent mechanical property of the composite material can be guaranteed, and heat stability is improved greatly.
