摘要

我国高端减震领域的恒黏天然橡胶(CV-NR)严重依赖进口，国产CV-NR与进口CV-NR的加工工艺相比存在差异，使得国产CV-NR的贮存稳定性较差，进而影响CV-NR的结构与性能. 本工作对CV-NR不打包、打包和干搅打包3种不同的加工工艺所得3种橡胶样品进行本征性能、微介观结构及硫化胶力学性能分析，研究加工工艺对CV-NR结构与性能的影响. 结果表明，打包处理不会影响CV-NR的本征性能和微介观结构，干搅打包处理会降低其门尼黏度、塑性初值、大凝胶含量、分子量和支化程度. 打包和干搅打包处理不会影响CV-NR的常规力学性能，干搅打包处理的CV-NR动态力学性能更好.

Abstract

High-end damping sector of China relies heavily on imported constant-viscosity natural rubber (CV-NR) products. Differences in processing technology between domestic and imported CV-NR lead to the poor storage stability of domestic CV-NR

which in turn affects its structure and properties. In this study

three distinct post-processing approaches

namely non-baling

baling

and dry-mixed baling

were applied to the CV-NR. The intrinsic properties

micro-mesoscopic structure

and mechanical properties of vulcanizates were characterized to investigate the effects of different processing techniques on the structure and properties of CV-NR. The results demonstrated that the baling treatment exerted no significant influence on the intrinsic properties and micro-mesoscopic structure of CV-NR. In contrast

dry-mixed baling treatment reduced the Mooney viscosity

plasticity initial value

macrogel content

molecular weight

and branching degree. Furthermore

both baling and dry-mixed baling treatments showed negligible effects on the conventional mechanical properties of CV-NR

whereas the dry-mixed baling treatment imparted superior dynamic mechanical properties to CV-NR.
