(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.

丁基防水嵌縫膠(Ms聚合物)作為一種高性能環(huán)保密封材料,兼具硅酮和聚氨醋的優(yōu)點,在軌道交通領域具有巨大潛力。本研究針對一種典型的丁基防水嵌縫膠,通過模擬其在高原環(huán)境(高海拔、寬溫域、強紫外線)下的特殊老化條件,對丁基防水嵌縫膠本體的理化特性、與車體基材的粘附性以及抗剪切疲勞性能進行了系統(tǒng)試驗與分析,論證了丁基防水嵌縫膠在高原列車車體密封(如側墻板縫、車體焊縫、門窗框密封)中應用的優(yōu)越性、適配性與可靠性。
高原鐵路(如青藏鐵路)因其獨特的地理和氣候條件,對運行其上的列車裝備提出了極其嚴峻的挑戰(zhàn)。這些環(huán)境特點主要包括:高海拔與低氣壓(易導致密封材料發(fā)生蠕變和起泡)、強烈的紫外線輻射(加速高分子材料的老化與降解)、巨大的晝夜溫度變化(對材料的柔韌性與粘結耐久性要求極高)以及風沙與雨雪侵蝕。車體密封部件是保障列車氣密性、隔音性、防塵防水性及結構完整性的關鍵四,其性能直接關系到乘客舒適度、車內設備正常運行及車體結構疲勞壽命。
丁基防水嵌縫膠(MS Polymer)是近年來發(fā)展的新型彈性丁基防水嵌縫膠,它通過端硅烷基聚醚,兼具聚氨醋的強度與可涂飾性、硅酮的耐候性和硅烷偶聯(lián)劑的優(yōu)異粘結性能。此外,其具有無毒、環(huán)保、固化收縮率低等優(yōu)點。盡管該材料在建筑與汽車領域已得到廣泛應用,但在高原極端環(huán)境下軌道車輛密封應用研究尚不充分。
本研究旨在通過模擬高原的特殊環(huán)境條件對一款典型的丁基防水嵌縫膠進行系統(tǒng)性測試和分析,并結合其在極端施工條件下的工藝驗證,評估其性能如本體性能、粘附性能、耐候性能等),為其在高原列車車體如側墻板縫、車體焊縫及門窗框等部件中的應用提供依據(jù)與數(shù)據(jù)支持。http://www.mychangxin.com/
