ИСПОЛЬЗОВАНИЕ МОДИФИЦИРОВАННОГО УГЛИСТОГО СЛАНЦА МЕСТОРОЖДЕНИЯ БАЛА-САУСКАНДЫК В КАЧЕСТВЕ ДИСПЕРСНОГО НАПОЛНИТЕЛЯ ДЛЯ ПОЛИЭТИЛЕНА

Abstract

Currently, researchers are paying great attention to the use of waste from the mining and metallurgical industries as components of polymer composite materials. This makes it possible not only to use them as a valuable secondary resource, to create new composites with certain consumer qualities, to expand the range of polymer products, but also to solve a number of environmental problems. The influence of a new modified filler of natural origin obtained from waste from autoclave leaching of vanadium ore at the Bala-Sauskandyk polymetallic mine on the properties of high-pressure polyethylene has been studied. The carbon-containing filler (CF) has a complex chemical composition. It contains 43.0-45.0% carbon, 48.0 - 51.0% silicon dioxide and a number of oxides, including metal oxides. Since the synergistic effect of the combined use of carbon black and silicon dioxide in rubbers is known from the literature to increase its strength, it was interesting to explore the possibility of using a new modified natural filler in polyethylene compositions. The effect of the new filler on the deformation and strength characteristics of polyethylene compared with talc is compared. It has been established that polyethylene filled with CF has better consumer properties than filled with talc. Thus, the use of CF filler obtained from waste after autoclave leaching of vanadium ore as a filler for polyolefins is promising for reducing the cost of polymer composite materials, expanding their range and reducing the environmental burden. This will expand the approach to the use of waste-free technologies in polymer materials science.
