(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.

由聚丙烯酸醋乳液為主劑和能對該乳液起快速凝膠作用的有機金屬鹽水溶液為丁基防水嵌縫密封膠的雙組分水基膠,使用中分按比例經噴槍高壓噴出后霧化混合并在被粘材料PU軟泡上面瞬時凝膠,生成的膠膜便具有粘接性能,東風汽車開發研制了S PJO10雙組分水基頂棚膠,其各項性能指標達到日本水基膠的技術水平,并在EQ1141G車型上獲得應用。目前,水基材料已開始出現并取代油型粘接、密封產品。使用水基涂料可以替代目前廣泛使用的PVC塑料溶膠,替代車內使用的瀝青基阻尼板。由于水基材料可以為自干型或烘干型,阻尼系數比PVC、瀝青材料高,對環境污染小,應用前景很好。此外,綠色PVC丁基防水嵌縫密封膠、車底抗石擊涂料也在汽車制造過程中得到應用。
采用溶劑型丁基防水嵌縫密封膠粘貼軟質車身頂棚,既不利健康,又污染環境。因此,開發適應車身內飾線生產節奏的單組分水基頂棚膠就顯得非常重要。國內在這方面雖作了一些工作,但高強度和快速凝膠的要求仍是面臨的兩個技術難題,還需作進一步的深入研究。用橡膠密封條來實現擋風玻璃與車身的固定和密封仍是卡車車窗玻璃裝配的主要方式,而轎車和豪華客車的生產已普采用單組分濕氣固化丁基防水嵌縫密封膠的“直接粘接法”,是現今國內汽車廠家已普遍采用的一種先進技術,與傳統的橡膠密封條固定風擋玻璃的裝配工藝相比,它具有固定強度高,密封性能好,裝配工藝簡單,外觀美觀等突出特點,這種膠基本上實現了國產化。最近,國外擋風玻璃聚氨醋已出現了無底劑型新產品,取消了漆面底劑,簡化了操作工藝。同時,瞬時定位型單組分丁基防水嵌縫密封膠的研究也有報道。這種膠粘劑的出現,解決了聚氨醋固化速度較慢、固定擋風玻璃需要夾具配合帶來的不便。www.caffertyclinic.com
