(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)选择适合于硅烷封端树脂材料的添加型阻燃剂和阻燃协效剂，通过添加阻燃剂的方式来获取阻燃功能化聚氨酯密封胶。这类阻燃聚氨酯密封胶的优势在于成本低、易操作，缺点在于添加型阻燃剂可能影响聚氨酯密封胶性能，且阻燃剂以发生迁移而导致阻燃效果无法持久。

(2)选择适合的与基础树脂能够发生化学反应的反应型阻燃剂或者以具有本质阻燃性能的阻燃型硅烷封端树脂为基础树脂，这两类方法均可以获得耐候性佳的阻燃功能化聚氨酯密封胶。这类聚氨酯密封胶的优势在于聚氨酯密封胶性能稳定、阻燃性能持久有效、耐候性较好。因此反应型本质阻燃研究应该得到更多的关注。

我国对于湿气固化硅烷封端树脂材料的研究尚处于初级阶段，无法掌握大规模合成该类树脂的工艺，生产供应均被国外垄断，研究主要集中在聚氨酯密封胶的应用研究上，难以获得这一领域的话语权。未来研究方向为:

研究硅烷封端树脂的合成方法和大规模生产工艺，摆脱国外垄断，赢得市场话语权。

探索拓展硅烷封端树脂材料的应用领域，提高其市场认可度。

在硅烷封端树脂聚氨酯密封胶领域，深人推进透明、高位移、透气、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视。http://www.sdyuantai.com/
