Abstract
The effect of the microwave electromagnetic field on the physicochemical and mechanical characteristics of epoxybasaltoplastics is investigated in this work. The thermal effect of the microwave electromagnetic field in the range of 100-700 W has been proved, which is due to the chemical composition of basalt, namely, the content of metal oxides. The study of the kinetics of curing showed that the effect of microwave EMF on the epoxy oligomer reduces the gelation and curing time compared to the unmodified oligomer, which is associated with a decrease in the viscosity of the oligomer. Optimal parameters of microwave processing of the epoxy oligomer have been selected, ensuring the improvement of the entire complex of characteristics. There was an increase in the destructive stress during bending by 65%, impact strength by 14%, hardness by 11%.
