Characterization of Elastomer Nanocomposite Blends Based on NR/EPDM/Organoclay

摘要

Elastomer nanocomposites based on NR/EPDM/organoclay were prepared by two-roll mill to investi-gate the effect of different percentages of nanoclay (0, 1, 3, 5 & 7 Wt%) and different matrix compositions (100/0, 75/25, 50/50, 25/75 & 0/100) on the microstructure, mechanical properties and best applicability of the mathematical models. Results of X-ray diffraction showed that enlargement of the silicate layers, pene-tration of polymer chains into layers and formation of an intercalated and exfoliated structure which was confirmed by TEM analysis. Mechanical properties as well as heat build up of the samples improved by addition of nanoclay. Addition the compounds with EPDM leads to an increase in compression strength, modulus and compressin set and decrease in tensile and tear strength. The prepared samples receive more aging resistance by addition of more clay and EPDM.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35610
