高疲劳寿命氯丁橡胶基减振材料的结构与性能
|
摘要
以氯丁橡胶(CR)为基体材料,将新型反式-1,4-丁二烯-异戊二烯共聚橡胶(TBIR)引入传统CR减振基体中,探讨TBIR在减振材料中的应用前景.研究发现,随着TBIR用量的增加,CR/TBIR混炼胶的强度及模量明显提升; CR/TBIR硫化胶的拉伸强度、撕裂强度、压缩永久变形、动静刚度比及耐疲劳性能均得到改善,特别是一级疲劳寿命提高了50%～400%(未填充体系)及40%～180%(填充体系),六级疲劳寿命提高了60%～500%(未填充体系)及30%～120%(填充体系).与未填充CR/TBIR硫化胶相比,填充CR/TBIR硫化胶由于炭黑补强作用及填料-聚合物相互作用的引入,屈挠疲劳寿命、撕裂强度及拉伸性能均显著提高.与填充CR硫化胶相比,填充CR/TBIR质量比为90/10的并用胶能够在保持硫化胶的损耗因子基本不变的基础上,实现综合性能的平衡提升.
A new type of synthetic trans-1,4-poly( butadiene-co-isoprene) copolymer rubber( TBIR) was introduced into the traditional chloroprene rubber( CR) as damping matrix for railway track damping rubber cushion. It was found that CR/TBIR blends exhibited excellent comprehensive properties including significantly increased tensile strength and modulus of the CR/TBIR compounds,the obviously improved tensile strength,tear strength,compression permanent deformation,dynamic and static stiffness ratio and fatigue resistance of the CR/TBIR vulcanizates. Especially,the 1 st flexural fatigue lifetimes showed 50%—400% improvements for unfilled CR/TBIR vulcanizates and 40%—180% improvements for the filled CR/TBIR vulcanizates; the 6th flexural fatigue lifetimes showed 60%—500% improvements for the unfilled CR/TBIR vulcanizates and 30%—120% improvements for filled CR/TBIR vulcanizates. Compared with the unfilled CR/TBIR vulcanizates,the 1st flexural fatigue lifetime,tear strength and tensile property of the filled CR/TBIR vulcanizates improved greatly,which were attributed to the better filler dispersion and improved filler-polymer interactions in the CR/TBIR vulcanizates. Compared with pure CR vulcanizate,m( CR) ∶m( TBIR) = 90 ∶ 10( mass ratio) vulcanizate exhibited balanced comprehensive performances with loss factor changed little.
