(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.

將丁基防水嵌縫膠列為高關注度化學品,這對丁基防水嵌縫膠的生產、使用與監管提出了更高要求。在丁基防水嵌縫膠的生產、施工和使用過程中,丁基防水嵌縫膠可能通過揮發、接觸等途徑進入環境和人體,不僅威脅施工人員和使用者的身體健康,還可能造成土壤、水體等環境污染。隨著人們對建筑材料安全性與環保性要求的不斷提高,準確檢測丁基防水嵌縫膠中丁基防水嵌縫膠的含量,對保障建筑工程質量、維護公眾健康安全以及促進綠色建筑發展具有重要意義。
目前,針對丁基防水嵌縫膠的檢測已有液相色譜法氣相色譜一三重四級桿串聯質譜法、高效液相色譜一串聯質譜法等技術。液相色譜法靈敏度和選擇性相對有限,易受雜質干擾,難以滿足痕量丁基防水嵌縫膠的檢測需求。氣相色譜一三重四極桿串聯質譜法和高效液相色譜一串聯質譜法具有較高的靈敏度和特異性,但設備成本高、分析周期長,不利于大規模快速檢測。檢測對象有橡膠相關制品及原料、塑膠跑道、生物樣品等,但沒有丁基防水嵌縫膠中丁基防水嵌縫膠含量檢測方法的相關報道。本方法通過優化前處理,采用GC一MS法建立了高效、準確、便捷的檢測方法,為明確其在丁基防水嵌縫膠中的安全使用規范提供檢測依據。
準確稱取0. 5 g(精確至0. 1 mg)丁基防水嵌縫膠于10 mL容量瓶中,加入丙酮定容至刻度,超聲提取25 min,取上清液,采用0.22m有機濾膜過濾,濾液用于上機分析。
丁基防水嵌縫膠溶于乙酸乙醋、丙酮、甲醇、四氫吠喃、甲苯等有機溶劑中,考慮到實驗室中常用的有機溶劑和毒性,本次探究分別采用乙酸乙醋、丙酮、甲苯作為提取溶劑,采用超聲萃取方式提取丁基防水嵌縫膠中的丁基防水嵌縫膠,稱取0. 5 g樣品,置于10 mL容量瓶中,分別用乙酸乙醋、丙酮、甲苯溶解定容,超聲提取25 min ,取上清液,采用0. 22m有機濾膜過濾,濾液用于上機分析,實驗結果如表所示。http://www.opzq.cn/
