中文摘要: |
将干冰用于氧化石墨烯(GO)/白炭黑/天然胶乳(NRL)的混合乳液中,利用干冰气化产生的大量气泡破裂而
形成的能量对填料聚集体的破碎作用,提高填料在NRL中的分散性,研究干冰用量对GO/白炭黑/天然橡胶(NR)复合材
料性能的影响。结果表明:干冰用量较小时,随着干冰用量的增大,复合材料的Payne效应减弱,交联密度增大,物理性能
提高,滚动阻力降低;干冰用量较大时,复合材料的Payne效应增强,交联密度减小,物理性能下降,滚动阻力提高;干冰用
量为20份时,复合材料的物理性能最佳。 |
英文摘要: |
The dry ice was applied in the mixed emulsion of graphene oxide(GO)/silica/natural latex
(NRL),the fragmentation action of energy generated by the breaking of a large number of bubbles due to dry
ice gasification was used to crush the filler aggregate in order to improve the dispersion of fillers in NRL,and
the effect of the addition level of dry ice on the properties of GO/silica/natural rubber(NR) composites was
studied.The results showed that,when the addition level of dry ice was small,with the increase of the addition
level of dry ice,the Payne effect of the composites was weakened,the crosslinking density and the physical
properties increased,and the rolling resistance decreased. When the addition level of dry ice was large,the
Payne effect was strengthened with the increase of dry ice amount,the crosslinking density and the physical
properties decreased,and the rolling resistance increased. It was found that the physical properties of the
composites were the best when the addition level of dry ice was 20 phr. |
