| Abstract: |
| In this paper,we have studyed the Mechanical property、Hot air aging and the Ozone resistance of light colored rubber compounded prepared by NR/EPDM.At the same time, the elastomer PNE was used to increase the compatibility of NR/EPDM blends. The results show that: with the increase of the dosage of EPDM,the Mechanical properties of NR/EPDM decreased, ozone aging properties and hot air aging properties improved; and treated with a certain amount of compatibilizer can improve Mechanical properties and flex resistance of NR / EPDM blends ; By comparing these different SEM images which have added different amount PNE,we can see the interface of material became blurred;by dynamic mechanical analysis, we can see with the addition of compatibilizer the peak of tanδcurve changed from two to one, these phenomena indicating that the compatibilizer can significantly improve the compatibility of two kinds of rubber. |
