摘要

Abstract

Elastomers are extensively used in engineering,but their properties suffer when they are exposed to heat,ozone,UV radiation,and toxic chemicals.To improve their perform-ance for specific industrial applications,they are often blended with other materials.We blended chloroprene rubber with brominated butyl rub-ber and reinforced it with Ketjenblack(KB)in concentrations up to 20%.KB has a porous and fluffy morphology and a high specific surface area of 1347 m2/g.Tensile tests were conducted before and after exposure to UV,ozone,saline,petrol,and diesel environments,and their retention capacity was evaluated according to ASTM standards.Trans-mission electron microscopy revealed a uniform dispersion of KB filler.Tribological studies and barrier properties showed the best content of KB to be 10%because of its uniform dispersion.Thermal degradation kinetics were studied using Kissinger-Akahira-Sunose modelling to determine its activation energy.Dynamic mechanical analysis indicates a reduction of 5 ℃ in the glass transition for a 20%composite.These elastomeric blends can be considered cutting-edge materials with great potential for use in extremely harsh industrial applications.
