(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.

研究采用邵氏硬度計測試抗菌性MS密封膠的硬度，測試標準出自GB/T531-1999《硫化橡膠邵爾A型硬度試驗方法》;采用拉力材料試驗儀測試抗菌性MS密封膠的拉伸強度和斷裂伸長率，其中拉伸強度測試標準出自GB/T s28《硫化橡膠或熱塑性橡膠拉伸應力應變性能的測定》，斷裂伸長率測試標準出自GB/T 13477.8《建筑密封材料試驗方法第8部分:拉伸粘結性的測定》。

本次研究采用測角儀測試抗菌性MS密封膠表面的靜態水接觸角，靜態水滴液體積為1,L表干時間是衡量密封膠應用性能的重要指標，在表干時間較短的情況下，密封膠能夠在較短時間內干燥凝固，縮短羽毛球拍的膠粘時間，提高生產效率。抗菌性MS密封膠的表干時間測試結果如圖1所示。

由圖1可知，在C,8 -QAs摻量逐漸增加的過程中，抗菌性MS密封膠的表干時間隨之降低，說明C,8 -QAs能夠有效提升MS密封膠的固化速度。經試驗研究發現，QAS/PDMS-C-S%的表干時間相較于QAS/PDMS-C-O%縮短了1.6 h。出現該現象的原因在于，C,8-QAs中的季錢鹽基團((QAS)帶有一定的親水性，能夠聚集整個交聯體系中的水分，促進烷氧基基團的水解反應，加速形成交聯點s-o-s鍵，進而提升MS密封膠的固化速度。http://www.www.mobmib.com/
