(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

丁基防水嵌缝胶(Ms聚合物)作为一种高性能环保密封材料，兼具硅酮和聚氨醋的优点，在轨道交通领域具有巨大潜力。本研究针对一种典型的丁基防水嵌缝胶，通过模拟其在高原环境(高海拔、宽温域、强紫外线)下的特殊老化条件，对丁基防水嵌缝胶本体的理化特性、与车体基材的粘附性以及抗剪切疲劳性能进行了系统试验与分析，论证了丁基防水嵌缝胶在高原列车车体密封(如侧墙板缝、车体焊缝、门窗框密封)中应用的优越性、适配性与可靠性。

高原铁路(如青藏铁路)因其独特的地理和气候条件，对运行其上的列车装备提出了极其严峻的挑战。这些环境特点主要包括:高海拔与低气压(易导致密封材料发生蠕变和起泡)、强烈的紫外线辐射(加速高分子材料的老化与降解)、巨大的昼夜温度变化(对材料的柔韧性与粘结耐久性要求极高)以及风沙与雨雪侵蚀。车体密封部件是保障列车气密性、隔音性、防尘防水性及结构完整性的关键四，其性能直接关系到乘客舒适度、车内设备正常运行及车体结构疲劳寿命。

丁基防水嵌缝胶(MS Polymer)是近年来发展的新型弹性丁基防水嵌缝胶，它通过端硅烷基聚醚，兼具聚氨醋的强度与可涂饰性、硅酮的耐候性和硅烷偶联剂的优异粘结性能。此外，其具有无毒、环保、固化收缩率低等优点。尽管该材料在建筑与汽车领域已得到广泛应用，但在高原极端环境下轨道车辆密封应用研究尚不充分。

本研究旨在通过模拟高原的特殊环境条件对一款典型的丁基防水嵌缝胶进行系统性测试和分析，并结合其在极端施工条件下的工艺验证，评估其性能如本体性能、粘附性能、耐候性能等)，为其在高原列车车体如侧墙板缝、车体焊缝及门窗框等部件中的应用提供依据与数据支持。http://www.sdyuantai.com/
