(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.

中空玻璃耐紫外线辐照性能:按GB/I11944《中空玻璃》进行;粘结性能:按GB/T 13477《建筑密封材料试验方法》进行，H试样;热老化性能:按GB 16776《建筑用硅酮结构聚氨酯密封胶》进行;耐久性能:按GB 16776心建筑用硅酮结构聚氨酯密封胶》进行;热重分析:升温速率为10 ℃/min。掺油的中空玻璃聚氨酯密封胶与中空玻璃热熔丁基聚氨酯密封胶的相容性。

在讨论二者的相容性之前，先通过实验观察中空玻璃聚氨酯密封胶常用的增塑剂与热熔丁基聚氨酯密封胶的溶解或溶胀性，实验结果见表卜图t。

通过实验可以看出，矿物油对热熔丁基聚氨酯密封胶有明显的溶解性，而甲基硅油和酷类增塑剂则无任何溶解作用，与热熔丁基聚氨酯密封胶相容性好。矿物油又称石蜡油，是无色无味的透明液体，是由石油中提取的液态烃类混合物，含链烷烃和环烷烃。丁基橡胶则是一种非极性橡胶，且具有极低的不饱和度，溶解度参数为I5.8 (Jcm2)，其硫化胶在非极性溶剂中(如燃油、矿物油等)具有较强的溶解性，丁基橡胶与石蜡烃的混溶性好，与环烷烃的混溶性一般，与芳香烃的混溶性差。http://www.sdyuantai.com/
