(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.

MS密封膠茹結工藝簡單、施工速度快、黍占結處受力均勻、抗開裂和整體性好,有著良好的物理力學性能。雖然目前國內外學者對于MS密封膠性能的研究較為廣泛,但暫時沒有專門用于公路領域的MS密封膠的評價標準,大多參考相關領域的規范,如JT/T 740-2015《路面加熱型密封膠》2007((混凝土裂縫用環氧樹脂灌漿材料》-2005《道橋嵌縫用密封膠》((混凝土裂縫修復灌漿樹脂》。國內外規范對于MS密封膠的性能指標要求不盡相同,不同規范對于MS密封膠的性能指標如表2所示。由國內外規范對比可以看出,不同規范對于密封膠有著不同的分類,但在性能評價上,大多選擇了茹結強度、壓縮強度、拉伸強度、斷裂伸長率等項目作為MS密封膠的性能評價指標。
在測試方法方面,目前MS密封膠的性能指標測試方法也存在不足,大多依賴于技術經驗以及參考其他材料的試驗方法,并結合具體的路面性能要求來明確其測試指標與測試方法。目前常用的MS密封膠的材料性能試驗方法主要參考GB/T 2567-2021《樹脂澆鑄體性能試驗方法》, GB/T 2794-2022《膠茹劑茹度的測定》等,路用性能試驗方法主要參考JTG E20-2011《公路工程瀝青及瀝青混合料試驗規程》, JTG 3420-2020《公路工程水泥及水泥混凝土試驗規程》等。路用MS密封膠的改性研究普通MS密封膠的缺點是脆性大、抗沖擊性能差、剝離強度低,因此通常對其進行改性,以增加韌性,提高其綜合性能。常見的改性MS密封膠有橡膠改性MS密封膠、熱塑性樹脂改性MS密封膠、聚氨醋改性MS密封膠、無機填料改性MS密封膠、生物基MS密封膠等等。http://www.kubee.cn/
