INNOVATIVE APPLICATION OF ALUMINUM SILICATE MICROSPHERE (CENOSPHERE) AS AN EFFECTIVE FILLER IN COMPOSITE MATERIALS

Abstract. Aluminosilicate microspheres as industrial waste of thermal power plants as a result of the combustion of thermal coal are widely used in various industries due to the uniqueness of their physical and chemical properties. The paper considers the use of aluminosilicate microspheres in the technologies of creating composite materials based on butadiene-styrene and nitrile rubbers with increased properties of the obtained materials for abrasive wear. Changes in the typical characteristics of the obtained rubber composite materials due to the addition of aluminosilicate hollow microspheres in the amount of 1 to 8 mass percent to the rubber matrix were studied. The deformation-strength characteristics of the latest composites and the effect of aluminosilicate microspheres on the creation of tribotechnical polymer materials for general purposes are determined. It is shown that increasing the amount of aluminosilicate hollow microspheres in the range from 2 to 8 mass percent to butadiene-styrene and nitrile rubbers contributes to the stabilization of wear intensity values, which is a positive technological factor in the creation of composite materials with an innovative filler.

Keywords: aluminosilicate microspheres, butadiene-styrene, nitrile rubber, tribotechnical materials, deformation-strength characteristics, friction.
