(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.

Information

       这类硅烷改性聚氨酯密封胶具有室温固化快、拉伸强度高、透明度好,被粘表面无需特殊处理等优点,广泛应用于各行各业。双组分(A/B组分)硅烷改性聚氨酯密封胶是以丙烯酸醋的自由基共聚为基础合成的。其中A组分以MMA、弹性体、引发剂、氯磺化聚乙烯配成溶液作为主剂,B组分以弹性体、MMA、促进剂、溶剂为底剂。多组分硅烷改性聚氨酯密封胶是在双组份硅烷改性聚氨酯密封胶基础上引人第三种或第三种以上组分形成的硅烷改性聚氨酯密封胶。

       由于环氧树脂具有耐水性、粘接力强、使用温度宽、固化收缩率小、良好的电绝缘性、耐腐蚀、自重轻使用方便等优点,使得环氧树脂受到了人们的重视。环氧树脂防水材料中的环氧树脂是一种液态的树脂,其基本组成成分是环氧树脂和固化剂。根据不同的使用场合,可调节不同物质进行复配,从而达到理想效果。复配的物质包括稀释剂、固化促进剂、偶联剂、阻燃剂、增韧剂、着色剂和稳定剂等。施工时将环氧树脂和固化剂搅拌混合均匀,涂抹在钢桥面上,待其固化后就会形成一层具有防腐性、防水性和粘接性的有机致密分子膜。根据固化反应的特征可分为环氧树脂粘接剂I型和环氧树脂粘接剂II型。环氧树脂粘接剂I型是在施工的过程中环氧树脂和固化剂一次性固化完成,固化后的涂层具有较高的强度,从而保护钢板。环氧树脂粘接剂II型是在施工期间先预交联,再根据要求完全固化。预交联的优点是可以与后期的施工提供一定的操作条件,预固化后再摊铺沥青混合料,由于混合料温度的作用,为环氧树脂粘接剂提供了固化反应的动力,从而进行第二次反应达到完全固化效果,进而完成最后的铺装。http://www.sdyuantai.com/
