Radiation Resistance Of Filled Elastomer Compositions

Abstract

Abstract The paper investigates the physical and chemical properties of the carbon-containing material of the secondary raw material for the production of acetylene and its effect on the radiation resistance of rubber products and cable rubbers. It was found that the carbon-containing material is modified carbon, the surface of which is microencapsulated with oligomeric oxygen-containing compounds, its thickness, calculated from the value of the specific geometric surface, amounted to 50-60Å. The effect of carbon-containing material on the relaxation coefficient and compressive stress is shown, and radiation resistance by the relative elongation of rubbers in an ionizing radiation environment 60Co. At the same time, it was found that, due to the finished oligomer on the surface of particles of carbon-containing material, threshold dose of radiation of rubbers based on styrene butadiene rubber according to the relaxation index, compressive stress and the coefficient of radiation resistance in terms of relative elongation increases three times compared to carbon blacks P803. Similarly, dependencies were obtained in rubbers based on other types of rubbers, including nitrile butadiene rubbers, possessing low radiation resistance due to the increased tendency to structuring. The findings indicate that the carbon-containing material is an effective filler for increasing the radiation resistance of industrial rubber goods and cables, operated in the environment of ionizing radiation.
