Simultaneously Improved Curing, Mechanical, Antioxidative Properties and Reduced ZnO Loading of Silica Filled NR Composites by Incorporation of Low-cost Crude Carbon Dots via Conventional Melt-milling Method
crude carbon dots (CCDs) were used as multifunctional additives for natural rubber/silica system. The results revealed that the CCDs could endow the rubber compound with excellent anti-aging capability
higher curing rate
better mechanical performance
lower rolling resistance and effectively reduce the ZnO dosage by at least 40%.
Abstract
Rubbers or elastomers play an important role in hi-tech technology and civilian daily life because of their unique and strategical properties. Generally
the rubber additives are essential components for rubbers' practical application. Nowadays
developing novel multifunctional additives has attracted increasing research attention. In this work
low-cost crude carbon dots (CCDs) were used as m
ultifunctional additives for natural rubber/silica system (without any additional modification) through industrial compatible melt-mixing method. The results revealed that the CCDs could disperse well in the NR/silica system
and they could not only endow the rubber compound with excellent anti-aging capability due to CCDs' radical scavenging activity because of their plenty of nitrogen-containing species
but also improve the curing rate and mechanical performance of the rubber composite. Also
the CCDs could reduce the rolling resistance of the rubber composites (tan
δ
value at 7% strain of the rubber composite could be decreased by 34%)
which is promising for the application of energy-saving tire industry. Lastly
the addition of CCDs could effectively reduce the ZnO dosage by at least 40% in the rubber composite without deteriorating its performance. Overall
this work provides valuable guidance to develop novel cheap yet effective additives for the elastomer.
