PREPARATION OF HNBR/PMgMA/OMT NANOCOMPOSITES AND THEIR AGING RESISTANCE IN DIFFERENT MEDIA
Nanocomposites composed of hydrogenated nitrile rubber/magnesium methacrylate/organic montmorillonite (HNBR/PMgMA/OMT) were prepared by in situ polymerization and mixing intercalation.The structure
morphology and properties of the nanocompostie were investigated by XRD
SEM
TEM
etc.The nano-micro coexistence structure was formed by PMgMA ion clusters and MgMA monomer.MgMA significantly enhanced the properties of HNBR composites.HNBR/PMgMA/OMT nanocomposites have favorable processing
mechanical properties and resistant aging properties in different media.TEM images revealed that MgMA can help OMT in exfoliating and dispersing
while the composition of MgMA/OMT facilitated the peeling and dispersion of OMT.OMT in the vulcanizates formed a microstructure mainly caused by exfoliation and intercalation
and also by the coexistence of de-intercalation and un-intercalation.SEM results indicated that the interface bonding can be significantly improved with a mixing ratio of MgMA/OMT as 20/10
therefore
the tensile strength
elongation at break and permanent deformation reached 30.2 MPa
520% and 30%
respectively; meanwhile
the hot air
oil and water resistant properties were also improved apparently.An aging coefficient of 0.61
0.63 and 0.84 was attained after aging at 165℃ in air
water and oil
respectively
for 14 days.And the resistant aging property of medium is higher than that of the HNBR composite reinforced by carbon black and MgMA
respectively.The improvement of aging resistance in different media is mainly due to the better dispersed layer structure of organic montmorillonite.
