基于电子产品应用的无卤涂料制备研究 摘 要 随着水性聚氨酯合成与改性工艺的不断进步，水性聚氨酯的应用也得到了极大地提升，反过来由于水性聚氨酯涂料的优异性能以及其极好的应用前景近些年来有关于水性聚氨酯的合成与改性研究也是如火如荼。本文主要研究了水性聚氨酯的结构与性能、制备，在阻燃剂探讨中分析了阻燃剂的分类、无机阻燃剂；在有机磷阻燃改性水性聚氨酯的研究中，设计了实验过程、进行了性能测试，最后给出了红外光谱分析、预聚体中P含量影响WPU乳液粒径以及极限氧指数及垂直燃烧研究 ；在对电子标签应用中水性聚氨酯的分析中 ，探讨了交联型PUA复合乳液、自交联型PUA复合乳液、互穿网络型PUA复合乳液、环氧树脂改性水性聚氨酯乳液，最后就电子标签天线基材中进行了应用研究。研究表明采用FRC-6替代其他小分子二醇扩链剂，能够合成大量的稳定的有机磷阻燃改性的水性聚氨酯；如果P含量保持在一定范围内，那么P含量在预聚体中质量分数的增加同时还会影响PU的热释放速率，即降低热释放量，增大LOI，提高阻燃性能等。如果P的含量在预聚体中的质量分数是端点2.31％，且氧指数是28％，UL-94V-2级就是垂直燃烧的PU的阻燃性能等级；将DMAc作为溶剂，能够提高预聚体反应效率。如果要得到外观较好的半透明乳液，预聚体中DMBA用量必须控制在5％。 关键字：水性聚氨酯；预聚体；无机阻燃剂；复合乳液；RFIF基材 Based on the electronic product application of halogen free coating preparation research Abstract Along with the water-borne polyurethane synthesis and modification technology advances, the application of waterborne polyurethane has been greatly increased, which in turn because of the excellent properties of waterborne polyurethane coatings and its good application prospect in recent years about the synthesis of waterborne polyurethane and modification research is also like a raging fire.
