(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.

       可知,在温度120℃长期老化至12个月过程中,丁基防水嵌缝胶1#,2#,5#,6#的大部分测试点拉伸粘接强度大于初始值,丁基防水嵌缝胶3#的大部分测试点拉伸强度小于初始值,丁基防水嵌缝胶2#,3#,4#呈现随时间延长拉伸强度逐渐下降的趋势。至12个月时,6个牌号丁基防水嵌缝胶试件未出现粘接破坏,强度变化率在一13.1%一++17.6%。

       可知,丁基防水嵌缝胶2#,3#在温度150℃环境放置8个月,拉伸粘接强度基本呈减小趋势;但丁基防水嵌缝胶2#大部分测试点拉伸粘接强度仍大于初始值。丁基防水嵌缝胶3#除3个月时外拉伸粘接强度均小于初始值。

       丁基防水嵌缝胶1#,6#老化后大部分测试点拉伸粘接强度大于初始值,但无明显趋势。所有试件在温度150℃中放置8个月时均已失去弹性,强度变化率在一28.0%一26.0%。结合表2,丁基防水嵌缝胶1#,3#,4#分别在老化6,3和5个月开始出现粘接破坏现象,对强度的变化有一定的影响。

       可知,在温度180℃长期老化至5个月过程中,丁基防水嵌缝胶1#,2#,3#拉伸强度呈衰减趋势;丁基防水嵌缝胶4#,6#呈增大趋势,所有试件在5个月时均发生粘接破坏现象,强度变化率为一100%。http://www.sdyuantai.com/
