分别以氢氧化铝( ATH)、三聚氰胺磷酸盐( MP)及MP和季戊四醇( PER)复配体系为阻燃剂,制备了一系列无卤阻燃型EVA共聚乳液胶黏剂,采用热重分析( TGA)、极限氧指数( LOI)和锥形量热计试验( CCT)等手段研究了材料的燃烧性能、力学性能及热分解行为。结果表明,添加阻燃剂会提高体系热分解的温度,ATH和MP添加量均为30%,m(MP)∶m(PER)为3∶1(MP和PER总用量为30%)时,改性体系LOI值分别为38.6、34.3和36.3,均大于30,拉伸强度分别为10.13、13.18和11.28 MPa,均大于8.0 MPa,满足使用要求；ATH在改性EVA乳液胶黏剂时的阻燃效率高于MP体系和MP/PER复合体系,引燃时间、热释放速率、总生烟量和质量损失速率等参数均较优。 MP改性体系中加入少量PER对生成膨胀型炭质残渣有一定的促进作用。

A series of halogen-free flame retardant EVA copolymer emulsion adhesives were synthesized with the blend of ATH, melamine phosphate ( MP) , and the complex system of MP and pentaerythritol ( PER) as flame retardants respectively. Limiting oxygen index ( LOI) and cone calorimeter test ( CCT) for the characterization of burning behavior , thermal gravimetric analysis ( TGA) for the evaluation of thermal decomposition behavior, and tensile strength related to mechanical property, were carried out and investigated . The results showed that thermal decomposition temperature was raised after adding flame retardant. When the amounts of ATH and MP were 30% and m(MP)∶m(PER) was 3∶1(the total amount of MP and PER was 30%), the LOI and tensile strength of the system were more than 30 (38. 6, 34. 3 and 36. 3) and 8. 0 MPa (10. 13, 13. 18 and 11. 28 MPa), respectively. They met the requirement. EVA emulsion modified with ATH had higher flame retardant efficiency than those modified with MP and MP/PER complex system. Its parameters of ignitor firing time, heat release rate, total smoke production and mass loss rate and so on were better. It was found that the addition of a small amount of PER in MP modified system could promote the generation of the intumescent carbonaceous residue.
