微米级滑石粉补强丁腈橡胶的性能研究
Performance of Nitrile Rubber Filled with Micro-talc Powder
摘要
Abstract
In order to reinforce the nitrile rubber(NBR) with the micro-talc powder, the effects of the particle size and the content and the surface treatment by the silane coupling agent of the talc on the mechanical properties of NBR are studied in this paper. It is shown that the talc has better reinforcement results when its particle size is very small with its optimal content and NBR has the tensile strength of 13.5 Mpa and the tearing strength of 41.4 kN/m when the talc has the particle size of 2500 mesh and the content of 60phr, and that the comprehensive properties of NBR can be further raised with the tearing strength of 14.1 Mpa and the tearing strength of 48. lkN/m when the surface of the talc is treated by 1 % (mass concentration) KH550, and that the dispersivity and compatibility improved by KH550 between the talc and NBR have been verified through the SEM.关键词
