摘要

通过力学性能、扫描电镜（SEM）、红外光谱（IR)、X射线电子能谱（XPS）和热重（TG）分析，探讨改性硅藻土适合橡胶种类及对橡胶结构及热稳定性的影响，并与炭黑及白炭黑进行了对比研究。结果显示：改性硅藻土对氟橡胶（FKM）、丙烯酸酯橡胶（ACM）、三元乙丙橡胶（EPDM）、天然橡胶（NR）以及氯丁橡胶（CR）有增强作用，相容性较好，其中对FKM改性效果最明显，与白炭黑相比，其拉伸强度、扯断伸长率和耐磨性分别提高了28%、17%和30%；EPDM的拉伸强度、扯断伸长率和耐磨性分别提高了11%、12％和14%。并且改性硅藻土能够改善FKM和EPDM的耐热性能。

Abstract

The influence on the structure and thermal stability of the rubbers were studied by the mechanical properties

scanning electron microscopy (SEM)

infrared spectra (IR)

X-ray photoelectron (XPS) and thermogravimetric analysis(TG)

and compared with carbon black and silica. The results showed that the modified diatomite had good reinforcing effect on fluorine rubber (FKM)

acrylic rubber (ACM)

ethylene propylene diene monomer rubber (EPDM)

natural rubber (NR) and chloroprene rubber (CR)

the compatibility between the modified diatomite and the rubbers was good

and the modified effect for the FKM was the best in all rubber. Compared with the silica

the tensile strength

elongation at break and wear resistance of the FKM were increased by 28%

17% and 30%

respectively

and the EPDM was increased 11%

12%

and 14%

respectively. And the modified diatomite could improved the thermal properties of FKM and EPDM.
