(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.

人工加速老化试验是研究MS密封胶耐久性能的一般方法，通过在实验室中模拟服役条件，促进MS密封胶老化，从而研究胶体老化行为二研究指出，热、水、紫外光、机械应力和它们的招合作用是导致MS密封胶老化的主要因素。据此，国内外学者开展了人工加速老化试验，根据所考虑的环境因素不同进行分类总结。

单因素加速老化试验

随机选取了8种MS密封胶进行热老化试验，研究了MS密封胶的拉伸粘结强度、拉伸伸长率等力学性能随老化时问的变化规律。对不同交联密度的MS密封胶进行热老化试验，分析MS密封胶力学性能变化规律及交联密度对耐久性能的影响。也对聚氨醋密封胶和MS密封胶进行了热老化试验。以上研究的具体试验条件见表。

研制了一种新型紧凑型自动机械应力老化装置，分别测试了固化和部分固化胶体，采用了两种不同的循环程序来评估密封胶的机械应力老化性能。对MS密封胶进行了剪切应力老化试验。对MS密封胶进行了拉压应力老化试验。对多种MS密封胶进行了拉压应力老化试验，同时采用了不同温度和湿度的组合工况，试验所采用的循环方式按照ASTM C719-14E"，机械应力、温度和湿度同时循环变化。以上研究的具体试验条件见表。

选用了单、双组分共4个样品的MS密封胶以及3种类型的幕墙用铝型材(4种表面处理方式)，以铝型材和MS密封胶的i800剥离破坏面积和剥离粘结强度为性能评估指标，分别考察了热一水浸作用对MS密封胶长期粘结性的影响。采用水浸方法，研究了不同交联密度的MS密封胶的力学性能变化规律。

对聚氨酷和硅酮两种建筑密封胶进行了紫外光一热老化试验。对不同交联密度的MS密封胶进行紫外光一热老化试验。以上研究的具体试验条件见表。http://www.sdyuantai.com/
