在动力电池组封装技术中，导热硅烷改性聚氨酯密封胶因其独特的化学结构和性能优势而受到广泛关注。在动力电池组的应用中，导热硅烷改性聚氨酯密封胶不仅能够实现电芯问的高效薪接与固定，还能够有效传导电池二作过程中产生的大量热量，从而提升电池系统的散热效能，防止局部过热导致的安全风险。

综上所述，动力电池组封装是新能源汽车技术发展中的一个重要领域，对材料的性能要求极为严苛。导热硅烷改性聚氨酯密封胶作为动力电池组封装中的重要材料，在保证电池组稳定性能、热管理效果和安全性能力面发挥着关键作用。通过对导热硅烷改性聚氨酯密封胶的性能评价力一法、制备工艺参数的优化以及应用平卜能研究的探讨，有助于更好地理解X1:1应用这一材料，推动动力电池组封装技术的不断进步。本文合成了系列聚氨醋预聚体，将其用于制备双组分无溶剂硅烷改性聚氨酯密封胶，并利用红外光谱和核磁共振波谱证明预聚体和硅烷改性聚氨酯密封胶的结构。通过控制变量法研究了聚氨醋预聚体的异氰酸醋基质量分数(}NCO}、多元醇分子量、R值(硅烷改性聚氨酯密封胶中。H和I}1C0基团的摩尔比)对硅烷改性聚氨酯密封胶钻度和耐蒸煮性能的影响。结果表明，在。NC。为17%时，预聚体钻度较低，硅烷改性聚氨酯密封胶经水煮后的剥离力较高。当。NC。一定时，随着多元醇分子量减小，预聚体钻度增大，硅烷改性聚氨酯密封胶水煮前后的剥离力增加。在多元醇分子量为1 609 g/molN。为17%, R值为2.5时，水煮前后耐蒸煮聚丙烯流延膜层剥离力最高分别达到6.30 N和4.37 N。将该预聚体与多种B组分混合获得一系列硅烷改性聚氨酯密封胶，均满足国家标准GB/T 41168-2021对铝塑复合膜耐蒸煮性能的需求。http://www.sdyuantai.com/
