(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.

为了研究不同温度下，循环加载历史对硅烷改性聚氨酯密封胶材料的力学性能影响。对材料进行平均应变分步减小控制的循环载荷试验。每个温度环境为一组，试验共分为5组，每组分四步进行平均应变减小的循环加载，各个加载步骤之间以平均应变15%减小，每个加载步骤循环50圈。其中，加载步骤、应变幅值和应变加载速率保持恒定不变。结果如图3.8所示。
本章对HP-172B硅烷改性聚氨酯密封胶进行了不同影响因素条件下的强度试验和循环疲劳测试。首先，进行了温度扫描分析，确定了材料的玻璃化转变温度;然后，研究了温度变化、吸湿度变化和应变率变化对材料拉伸强度的影响;最后，研究了温度和循环加载历史对材料循环强度和疲劳寿命的影响。并分析了各个加载状态下，材料力学性能变化的原因。可得出以下结论:
温度扫描分析测出了材料的储存模量、损耗模量和损耗因子，并通过损耗模量确定了材料的玻璃化转变温度为228.670C。材料在该温度以下表现为玻璃态，超过该温度后呈现高弹态或粘流态。www.sdyuantai.com
