【 摘 要 】

It is shown by researches, made in Russia and abroad, that carbonic primary nanomaterials increase indexes of physic-mechanical properties of oil bitumen and building materials on its basis. Considerable technological problem, which restrains both theoretical knowledge development and practical realization of volumetrical materials nanomodification technology, is the absence of efficient way of carbonic primary nanomaterials distribution in the volume of oil bitumen. The results of realization of the way of combining mentioned nanomaterials with bitumen melt through inclusion of precursor compatible with all the components (oil bitumen and nanomaterials) are discussed in the work. Distribution of carbon primary nanomaterials in the carrier-medium is conducted with ultrasonic dispersion. In this research, studying of primary nanomaterials distribution was conducted with application of laser diffractometry, colorimetry, and calculation of disperse system range was conducted with application of Smolukhovskiy's theory. Kinetic parameters of disperse composition change are found out in process of precursor preparation the same as in process of its storing in normal conditions. According to the mentioned dependences optimal dispersion regimes were defined, which provide high aggregational and sedimentational resistance of precursor of carbonic primary nanomaterials.
