(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.

       可知,在溫度120℃長期老化至12個月過程中,丁基防水嵌縫膠1#,2#,5#,6#的大部分測試點拉伸粘接強度大于初始值,丁基防水嵌縫膠3#的大部分測試點拉伸強度小于初始值,丁基防水嵌縫膠2#,3#,4#呈現(xiàn)隨時間延長拉伸強度逐漸下降的趨勢。至12個月時,6個牌號丁基防水嵌縫膠試件未出現(xiàn)粘接破壞,強度變化率在一13.1%一++17.6%。

       可知,丁基防水嵌縫膠2#,3#在溫度150℃環(huán)境放置8個月,拉伸粘接強度基本呈減小趨勢;但丁基防水嵌縫膠2#大部分測試點拉伸粘接強度仍大于初始值。丁基防水嵌縫膠3#除3個月時外拉伸粘接強度均小于初始值。

       丁基防水嵌縫膠1#,6#老化后大部分測試點拉伸粘接強度大于初始值,但無明顯趨勢。所有試件在溫度150℃中放置8個月時均已失去彈性,強度變化率在一28.0%一26.0%。結(jié)合表2,丁基防水嵌縫膠1#,3#,4#分別在老化6,3和5個月開始出現(xiàn)粘接破壞現(xiàn)象,對強度的變化有一定的影響。

       可知,在溫度180℃長期老化至5個月過程中,丁基防水嵌縫膠1#,2#,3#拉伸強度呈衰減趨勢;丁基防水嵌縫膠4#,6#呈增大趨勢,所有試件在5個月時均發(fā)生粘接破壞現(xiàn)象,強度變化率為一100%。http://www.www.mobmib.com/
