(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

       這類硅烷改性聚氨酯密封膠具有室溫固化快、拉伸強度高、透明度好,被粘表面無需特殊處理等優點,廣泛應用于各行各業。雙組分(A/B組分)硅烷改性聚氨酯密封膠是以丙烯酸醋的自由基共聚為基礎合成的。其中A組分以MMA、彈性體、引發劑、氯磺化聚乙烯配成溶液作為主劑,B組分以彈性體、MMA、促進劑、溶劑為底劑。多組分硅烷改性聚氨酯密封膠是在雙組份硅烷改性聚氨酯密封膠基礎上引人第三種或第三種以上組分形成的硅烷改性聚氨酯密封膠。

       由于環氧樹脂具有耐水性、粘接力強、使用溫度寬、固化收縮率小、良好的電絕緣性、耐腐蝕、自重輕使用方便等優點,使得環氧樹脂受到了人們的重視。環氧樹脂防水材料中的環氧樹脂是一種液態的樹脂,其基本組成成分是環氧樹脂和固化劑。根據不同的使用場合,可調節不同物質進行復配,從而達到理想效果。復配的物質包括稀釋劑、固化促進劑、偶聯劑、阻燃劑、增韌劑、著色劑和穩定劑等。施工時將環氧樹脂和固化劑攪拌混合均勻,涂抹在鋼橋面上,待其固化后就會形成一層具有防腐性、防水性和粘接性的有機致密分子膜。根據固化反應的特征可分為環氧樹脂粘接劑I型和環氧樹脂粘接劑II型。環氧樹脂粘接劑I型是在施工的過程中環氧樹脂和固化劑一次性固化完成,固化后的涂層具有較高的強度,從而保護鋼板。環氧樹脂粘接劑II型是在施工期間先預交聯,再根據要求完全固化。預交聯的優點是可以與后期的施工提供一定的操作條件,預固化后再攤鋪瀝青混合料,由于混合料溫度的作用,為環氧樹脂粘接劑提供了固化反應的動力,從而進行第二次反應達到完全固化效果,進而完成最后的鋪裝。http://www.www.sunsage.net/
