摘要:
采用优化的Hummers法制备氧化石墨烯(GO),利用硅烷偶联剂KH550对其进行改性,得到改性氧化石墨烯(KH550-GO); 将其与蒙脱土(MMT)复合成二元填料添加到甲基乙烯基硅橡胶(MVQ)中,得到了KH550-GO/MMT/MVQ复合材料.研究了KH550-GO和MMT的纳米片层复合现象以及KH550-GO/MMT二元填料的添加对复合材料力学性能和阻燃性能的影响.结果表明:在超声后的水溶液中,KH550-GO和完全剥离的MMT可以形成复合纳米片层结构; 与纯MVQ相比,添加质量分数为5%的KH550-GO/MMT(质量比为3:2)后复合材料的拉伸强度提高到1.83 MPa,极限氧指数(LOI)从30.8%提高到38.5%,残炭率提高了7个百分点,炭层结构更加致密.
Abstract:
By modification of graphene oxide(GO)with γ-aminopropyltriethoxysilane(KH550),KH550-GO was made using Hummers method.KH550-GO/montmorillonite(MMT)was prepared as a flame retardant and a reinforcing agent to the methyl vinyl silicone rubber(MVQ)to obtain KH550-GO/MMT/MVQ composites.The effects of KH550-GO/MMT nanomaterials on the flame retardancy and mechanical properties of the composites were investigated.The results showed that MMT and KH550-GO crosslinked in the aqueous solution after ultrasonic treatment and produced hydrogen bonds,both of which formed nanocomposite lamellae.Compared with the pure MVQ,the performance of composite with 5%(by mass)KH550-GO/MMT(mass ratio of 3:2)was as follows:the tensile strength increased to 1.83 MPa,the limit oxygen index(LOI)increased from 30.8% to 38.5%,the carborn residue rate increased by 7 percentage points,and the thermal decomposition stability was greatly improved with more dense carbon residue.
