摘　　要：进入21世纪以来,石油基合成橡胶的发展不可持续,且日益受到节能减排的压力;天然橡胶面临气候、疫病等因素的影响,产量有限,而且我国天然橡胶自给不足,严重依赖进口。面对上述挑战,以太阳能为源头,开发不依赖于化石资源的新一代生物基橡胶,是解决橡胶资源短缺的有效手段,也是保证全球橡胶资源安全、长久、稳定供应的必由之路。目前,主要有两种思路制备生物基合成橡胶,本文针对两类生物基合成橡胶的研究进展进行综述,一种是生物质发酵得到的生物基单体(如乙醇等)进一步转化为传统单体(如乙烯等),再通过传统的合成工艺制备出生物基乙丙橡胶、生物基异戊橡胶等生物基传统橡胶,其性能与传统非生物基工程弹性体几乎完全相同,可以直接替代现有工程橡胶;另一种是利用现有生物基化学品,如衣康酸、丙二醇、丁二酸等,通过聚合反应制备新型结构的生物基橡胶材料,其原料易得,成本较低,随着发酵技术的快速发展,将出现越来越多的生物基化学品可以进行选择和使用,生物基合成橡胶具有光明的发展前景。As entering the 21st century,the development of petrochemical synthetic rubber is unsustainable,and is gradually constrainted by energy saving and emission reduction.The production of natural rubber is limited and affected by factors such as climates,epidemic diseases,etc.China’s natural rubber self-supporting is insufficient,rely heavily on imports.In the face of the above challenges,the development of a new generation of bio-based rubber resources independent of fossil resources from solar energy is an effective means to solve the shortage of rubber resources and the only way to ensure the safe,long-term and stable supply of global rubber resources.At present,there are two main ideas for the preparation of bio-based synthetic rubber.The research progress of two types of bio-based synthetic rubber was mainly reviewed in this paper.One is to further convert bio-based monomers(such as ethanol)obtained by fermentation of biomass into conventional monomers(such as ethylene),then the bio-based conventional rubber such as bio-based ethylene propylene rubber and bio-based isoprene rubber will be prepared by a conventional synthetic process,and its performance is almost identical to that of a conventional non-bio-based engineering elastomer,and the existing engineering rubber can be directly replaced;the other is to prepare a novel structure of bio-based rubber materials through polymerization using the existing bio-based chemicals,such as itaconic acid,propylene glycol,succinic acid,etc.The raw materials can be easily obtained,the cost is low,and with the rapid development of fermentation technology,more and more bio-based chemicals will be available for selection and use,and bio-based synthetic rubber has bright prospects.
