Abstract: |
Two series of compatibilizers for nitrile rubber(NBR)/polyurethane(PU) composites
were prepared by the reaction of hydroxy-terminated liquid nitrile rubber(HTBN) with diphenylmethane
diisocyanate(MDI) and p-chlorophenyl isocyanate(4CPI),respectively,which were HTBN-PU and HTBN-
4CPI,and their effects on the properties of NBR/PU composites prepared by mechanical blending method
were studied. The results showed that the compatibility of NBR and PU was effectively improved with the
addition of the compatibilizers,the tensile strength and storage modulus of NBR/PU composites increased,
and the abrasion resistance was improved. When the mass fraction of HTBN-4CPI was 0. 98%,the tensile
strength and storage modulus of the NBR/PU composite were the largest,the abrasion resistance was the
best. Compared with the composites without compatibilizer,the tensile strength increased by 35% and the
abrasion loss was reduced by 56%. |
