Abstract
Aim. The determination of the influence oligomeric rubbers of various chemical structures in the wear-resistant epoxy compositions on the main parameters of their processing and the establishment of directions for possible regulation of these parameters. Methods. The study tested by computational method for determining the compatibility of the components of the compositions, experimental - optical microscopy to confirm the calculated data of the compatibility of the epoxy matrix with oligomeric rubbers, static Wilhelmy when determining the surface tension of the constituent components of epoxy compositions, sessile «droplet» when wetting the surface of model high-hard fillers with constituents of the compositions and their combinations, the amount gel epoxy matrix - filler (silicon carbide), the temperature of the exothermic reaction of the interaction of the epoxy groups of the matrix with the amine groups of the hardener (polyethylenepolyamine). Results. The initial compatibility of the epoxy matrix (dian resin ED-20, aliphatic resin DEG-1) with oligomeric rubbers of various chemical structures is determined and experimentally confirmed by a calculation method, and the possibility of its improvement by using butadiene-nitrile rubbers with terminal hydroxyl (SKN-GTR) and carboxyl (SKN-KTR) groups with a high content (14-40% wt.) of acrylonitrile, oligoisoprene with terminal hydrazide (SKI-GDSH) groups. The influence of the components of wear-resistant epoxy compositions on the wetting of model high-hardness according to the Mohs scale of filler surfaces is established and it is found that oligomeric rubbers do not improve the wetting of the boron and silicon carbide surfaces and do not significantly affect this process when wetting electrocorundum; they also do not improve the spreading of epoxy composites filled with silicon carbide F1000, which is associated with an increase in the formation of the epoxy matrix-filler gel in their presence as compared to the unmodified ED-20 resin. The positive effect of oligomeric rubbers on a decrease in the temperature of the exothermic reaction of the curing of compositions, an increase in their "viability" as the main technological parameters in the processing of modified epoxy compositions is determined.
