摘要: 制备了天然橡胶(NR)/MCM--41--M、NR/偶联剂化学改性纳米介孔MCM--41--M、NR/MCM--41--M/偶联剂复合材料, 研究了不同含量的MCM--41--M、不同种类偶联剂对MCM--41--M的改性以及偶联剂的添加方式对NR复合材料性能的影响。结果表明:MCM--41--M在NR中有明显的补强作用, 当代替3份炭黑时NR基复合材料的拉伸强度达到最大值, 比纯NR提高了12.7%。与MCM--41--M和KH--570直接添加到NR中相比, MCM--41--M经偶联剂KH--570改性使拉伸强度提高了50%。将MCM--41--M用偶联剂KH--570改性后添加到NR中, 使NR的玻璃化转变温度升高、玻璃化转变区的损耗角减小、储能模量提高到最大。

Abstract:The nano–sized mesoporous MCM–41–M, chemical modification of MCM–41–M by coupling agents, and four different coupling agents were used to prepare natural rubber(NR) composites. The effects of content of nano–sized mesoporous MCM–41–M, the kinds of coupling agents, and adding method of coupling agent on the mechanical properties of the composites were investigated. The results show that the MCM–41–M has better reinforcing effects in the NR matrix. The tensile strength of the NR composites raised by 12.7% compared with pure NR when the content(mass fraction) of MCM–41–M is 3%. Compared with NR/MCM–41–M/KH–570, the tensile strength of NR/KH–570 modified MCM–41–M raised by 50%. NR/KH–570 modified MCM–41–M shows a higher glass transition  temperature, lower tanδ peak value and higher storage modulus under all temperature regions.
