(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.

由图可知:研究人员对丁基防水嵌缝胶的研究中，通过茹合剂材料的配方制备和应用以及通过高分子化合物、组合物合成胶粘剂这两个分支的创新热度较高。其中国内对基础聚合物合成的研究略少，主要采用外购聚合物，通过研究配方对丁基防水嵌缝胶的性能进行改进;另外，国内还有部分企业通过采用不同的MS基础树脂来改进所制备丁基防水嵌缝胶的性能。

技术的区域分布和申请人情况

在研究范围内专利申请中，申请硅烷改性聚由图可知:创新主体为企业(约87 %，科研单位或者高校类等其他研究占比较少，如因此，可知对硅烷改性聚醚的研究主要为应用研究，相应的创新成果更偏向商业应用。

在丁基防水嵌缝胶这一技术方向上，近20年里，在不同国家或地区的专利申请数量分布情况，如图所示。

丁基防水嵌缝胶的主链为聚醚、端基为硅氧烷封端，柔性的长链聚醚和封端的硅氧烷特殊结构，与密封胶的性能有密切关系，因此硅烷改性聚醚预聚体的合成对于丁基防水嵌缝胶的制备非常关键。

硅烷改性聚醚的合成与制备技术路线

对硅烷改性聚醚的合成，使用硅烷改性主链上含有聚醚、聚丙烯酞胺、聚氨醋等结构的聚合物及其掺合物，将其用作密封胶。后来，由日本钟渊化学(IANEIA)开发了硅烷改性聚醚的成熟产品。目前市面上的硅烷改性聚醚产品生产厂商主要有国内在MS胶基础聚合物这方面进行研究的有万华化学等。

开发一种硅烷封端聚醚预聚物的制备方法，以环氧化合物为原料，在金属氰化物的催化作用下聚合，得到一种聚醚多元醇;加人碱金属盐使聚醚多元醇的末端变为碱金属醇盐，再与烯丙基氯反应制备端烯基聚醚;最后在铂类催化剂的催化作用下，以硅烷化合物进行封端。http://www.sdyuantai.com/
