(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
分別取用120號汽油與壬烷作為溶劑，按照相同組分配比，制備兩組HM301刷涂型丁基防水嵌縫膠試樣:①硫化型丁基防水嵌縫膠A(120號汽油溶劑)、②硫化型丁基防水嵌縫膠B(壬烷溶劑)。通過掃描電鏡一能譜分析(SEM-EDS)、紅外光譜(FTIR)、核磁譜圖分析(NMR)、熱失重等表征手段，判定兩組試樣在硫化后，微觀形貌與元素成分有無差異，從而判斷壬烷溶劑是否與丁基防水嵌縫膠發(fā)生其他化學(xué)反應(yīng)、是否有揮發(fā)殘留。綜合各類表征手段，得出組分分析結(jié)果。綜上分析，120號汽油溶劑組與壬烷溶劑組在硫化后，可得出以下結(jié)論:
1)兩組丁基防水嵌縫膠樣品均未檢測出殘留溶劑，溶劑揮發(fā)充分。
2)兩組丁基防水嵌縫膠樣品的成分上相同。
3)兩組丁基防水嵌縫膠樣品的微觀形貌相同。
4)兩組丁基防水嵌縫膠樣品的熱失重曲線相同。
材料腐蝕性測試
依據(jù)HB5273-1993《室溫硫化丁基防水嵌縫膠腐蝕性試驗方法》、HB20542-2018《航空用高閃點溶劑型清洗劑規(guī)范》，對壬烷進(jìn)行全浸腐蝕、有機玻璃腐蝕、復(fù)合材料腐蝕等19項腐蝕性測試，均滿足技術(shù)要求。選取了ZL116材料、SA90材料、2D70材料、7B04材料、2B06材料幾種零件進(jìn)行刷膠測試，涂膠質(zhì)量均符合預(yù)期。主要指標(biāo)達(dá)標(biāo)情況見表80本項目基于《HM301室溫硫化耐高溫有機硅丁基防水嵌縫膠使用工藝要求》，綜合分析溶解性、揮發(fā)速率、阻燃性、實物質(zhì)量、安全生產(chǎn)等因素，確定了壬烷作為新型溶劑替代120號汽油配制刷涂型HM301丁基防水嵌縫膠的可行性與可靠性。通過實際生產(chǎn)中不同材料的刷涂測試，驗證了壬烷溶劑的工藝有效性，解決了120號汽油閃點低、易燃易爆的問題。http://www.mychangxin.com/
