(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.

       (1)選擇適合于硅烷封端樹脂材料的添加型阻燃劑和阻燃協效劑,通過添加阻燃劑的方式來獲取阻燃功能化聚氨酯密封膠。這類阻燃聚氨酯密封膠的優勢在于成本低、易操作,缺點在于添加型阻燃劑可能影響聚氨酯密封膠性能,且阻燃劑以發生遷移而導致阻燃效果無法持久。

       (2)選擇適合的與基礎樹脂能夠發生化學反應的反應型阻燃劑或者以具有本質阻燃性能的阻燃型硅烷封端樹脂為基礎樹脂,這兩類方法均可以獲得耐候性佳的阻燃功能化聚氨酯密封膠。這類聚氨酯密封膠的優勢在于聚氨酯密封膠性能穩定、阻燃性能持久有效、耐候性較好。因此反應型本質阻燃研究應該得到更多的關注。

       我國對于濕氣固化硅烷封端樹脂材料的研究尚處于初級階段,無法掌握大規模合成該類樹脂的工藝,生產供應均被國外壟斷,研究主要集中在聚氨酯密封膠的應用研究上,難以獲得這一領域的話語權。未來研究方向為:

       研究硅烷封端樹脂的合成方法和大規模生產工藝,擺脫國外壟斷,贏得市場話語權。

       探索拓展硅烷封端樹脂材料的應用領域,提高其市場認可度。

       在硅烷封端樹脂聚氨酯密封膠領域,深人推進透明、高位移、透氣、耐水、防霉、防腐等功能性改性研究,尤其是阻燃性能研究需要引起高度重視。http://www.16878m.com/
