(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.

本文系統(tǒng)的總結(jié)了有機硅材料在電池丁基防水嵌縫膠領(lǐng)域中的應(yīng)用以及研究現(xiàn)狀,首先介紹了有機硅丁基防水嵌縫膠在新能源汽車電池中的作用以及性能要求,其次總結(jié)了電池密封腳常用的性能測試方法,最后介紹了幾種新能源汽車電池包用膠茹劑的優(yōu)缺點。
盡管有機硅丁基防水嵌縫膠在耐高低溫性能、耐候性、耐化學(xué)腐蝕性、電絕緣性能和防震抗沖擊性能等方面具有顯著優(yōu)勢。然而,在汽車電池應(yīng)用領(lǐng)域還應(yīng)考慮到一些其他因素,涂膠方式應(yīng)盡量簡化,丁基防水嵌縫膠在電池箱體粘接面可快速鋪展,開發(fā)具有更低密度的丁基防水嵌縫膠來滿足新能源汽車更加輕量化的需求,這是其在應(yīng)用中需要進一步改進的地方。在新能源汽車電池的應(yīng)用中,可根據(jù)電池的具體使用環(huán)境和性能要求,綜合考慮選擇合適的丁基防水嵌縫膠以及涂膠方式,或通過對有機硅丁基防水嵌縫膠進行配方優(yōu)化和改性,提高其粘接強度,以更好地滿足電池密封的需求。
以低聚物多元醇(N220,N330和N303)為軟段、甲苯二異氰酸醋(TDI)和3,3一二氯-4,4一二氨基二苯基甲烷(MOCA)為硬段、辛酸亞錫為催化劑、鄰苯二甲酸二辛醋(DOP)為增塑劑和輕質(zhì)碳酸鈣(CaC03)為填料,合成了聚氨醞(PU)彈性丁基防水嵌縫膠。著重探討了不同助劑與PU彈性丁基防水嵌縫膠性能之間的關(guān)系。結(jié)果表明:當(dāng),(辛酸亞錫)=1%}2%,w(輕質(zhì)CaC03)=30%-70%和。(DOP)=5%-20%時,PU彈性丁基防水嵌縫膠具有較好的綜合性能、較適宜的表干時間和硬度。
彈性丁基防水嵌縫膠是一種集粘接和密封于一體的新型粘合劑,已在建筑、土木、汽車、船舶、電氣及民用等領(lǐng)域中得到廣泛應(yīng)用(其中建筑用丁基防水嵌縫膠的應(yīng)用范圍最廣)。性能較好的高檔彈性丁基防水嵌縫膠包括有機硅丁基防水嵌縫膠、聚硫丁基防水嵌縫膠和聚氨酷(PU)丁基防水嵌縫膠三類。PU丁基防水嵌縫膠具有耐磨性優(yōu)、低溫柔軟性佳、產(chǎn)品性能可調(diào)范圍廣以及價格適中等諸多優(yōu)點,是近年來發(fā)展較快、需求量較大的品種之一,其性能主要受預(yù)聚體、固化劑和助劑等影響較大。本研究主要考察助劑對彈性丁基防水嵌縫膠性能的影響,并通過比較產(chǎn)品性能、可操作性和價格等因素來優(yōu)選合適的助劑用量。http://www.jifengjixie.cn/
