摘要

天然橡胶中存在约3 wt%~7 wt%的非胶组分

这些非胶组分中的蛋白质、磷脂及金属离子通过氢键/离子键等弱价键将天然橡胶的线性分子链结构连接成超分子网络聚集态结构

进而使天然橡胶具有应变诱导结晶、切变模量自恢复性以及与金属良好的粘接性等优异性能

广泛应用于航空轮胎、工程轮胎、坦克负重轮、空气弹簧等极端服役工况领域

至今不可被合成顺式-1

4-聚异戊二烯橡胶(简称异戊橡胶)所替代。本文首次以非胶组分对于天然橡胶超分子网络聚集态结构的构建以及结构对于性能的影响关系为主线

概述了非胶组分的种类、含量及检测方法

总结了非胶组分在形成天然橡胶超分子网络聚集态结构中所起的作用

阐明了天然橡胶超分子网络聚集态结构与优异性能之间的关系

并展望了未来的研究方向。

Abstract

Natural rubber (NR)includes about 3 wt%~7 wt% none rubber components (NRCs). It is the NRCs that have transferred the structure of NR from linear to supramolecular by the means of non-covalent interactions such as hydrogen bonding

ionic bonding. The above unique structure has given irreplaceable properties such as strain induced crystallization

modulus self-recovery after shearing and good adhesion to metal compared with Isoprene Rubber (IR). Because of the above properties

NR has widely used in aviation tires

engineering tires

tank roadwheels

air springs and other extreme service conditions. In this article

we make a systematic and comprehensive summary of this field based on effects of NRCs on relationship between supramolecular structure and performance of NR. The species

content and methods for determining content of NRCs have firstly introduced; three aspects are discussed in more detail: the structure of modified end groups of polymer

the mechanism for supramolecular structure and the relationship between the structure and performance. Meanwhile

the future direction of development is discussed as well.
