摘要
天然橡胶(NR)作为一种可再生资源,因其优异的综合性能,广泛应用于航天、军工、医用弹性体等领域。但是,NR是非极性不饱和橡胶,其耐油、耐有机溶剂、耐热氧老化、耐臭氧和抗紫外线性能较差,限制了它在一些特殊场合的应用。近年来,天然橡胶的改性引起了广泛的关注。本文从化学改性、共混改性和无机纳米改性三个方面介绍近几年的研究进展,并对未来天然橡胶改性做出了展望。
As renewable resource,natural rubber(NR)has been widely used in many applications including aerospace,war industry and medical treatment due to its excellent comprehensive performances.However,the poor resistances to oil,organic solvent,thermo-oxidative ageing and ultraviolet rays,which drives from its nonpolar and unsaturated chemical chain structures,NR is underperformed in some special fields.Therefore,the modification of NR has attracted great attention in both academia and industry.Herein,the progresses achieved in the recent years are summarized from three aspects,i.e.chemical modification,bleeding modification and organic fillers-filled modification.
