Title of the articleComparison of modifying action in epoxy compositions of diopside containing fillers based on technogenic and vegetable raw materials
Abstract.Natural diopside has high electrophysical and strength characteristics, as well as resistance to acids, which causes its use in various types of ceramics. In addition, it is quite effective as a filler of polymer materials, which is shown by the example of polyester resins. However, due to the high cost of extraction and high labor costs for grinding solid rock, dispersed diopside-containing filler is practically absent on the domestic market. In this regard, the main problem is the uneven distribution of the diopside deposit across the territory of Russia. This makes it relevant to synthesize diopside-containing fillers based on available, inexpensive domestic raw materials, in particular, metallurgical slag and rice husk ash. The purpose of the work is to study the phase composition and properties of diopside - containing fillers based on man - made and vegetable raw materials and to study their modifying effect in epoxy compositions to improve the complex of performance indicators. The objectives of the study to achieve this goal are to study the basic properties of diopside-containing fillers, such as phase composition, porosity, surface pH, oil capacity; analysis of the physical and mechanical characteristics of epoxy compositions filled with these fillers. Results. The paper presents the results of studies of diopside-containing fillers obtained on the basis of ferrous metallurgy waste and rice cereal production. The filler based on metallurgical slag contains 4 times less amount of the target product – diopside than the one obtained on the basis of rice husk ash. The diopside-containing filler based on metallurgical slag has significantly lower porosity compared to the filler, which is synthesized on the basis of rice husk ash. The specific surface area of its pores is less by 30%. Modification of epoxy polymers with diopside-containing fillers provides a significant reduction in the coefficient of friction and an increase in the wear resistance of materials based on them, that is, their high tribological characteristics. At the same time, the hardness of the filled compositions and their adhesion to steel increases. Conclusions. The use of diopside-containing fillers is effective for the modification of epoxy polymers and the development of protective coatings of metal structures and adhesive compositions based on them.
