Abstract
The composition, physical-mechanical and structural features of polyamide-6 modified at the stage of synthesis by basalt fillers are investigated. The influence of the introduced fillers on the structural features, deformation-strength, technological and physic-chemical properties of the synthesized polymer is established. The positive effect of heat treatment of fillers on their adhesion interaction with the polymer matrix in the synthesis of the composite is revealed. It is shown that with the introduction of a fibrous filler of more than 7.5 wt%, there is a tendency to increase the physical and mechanical characteristics of the synthesized polymer. The behavior of the synthesized composite under high temperature conditions was evaluated by thermogravimetric analysis, which showed that the thermal treatment of basalt fiber can significantly increase the activation energy of destruction, which confirms the effectiveness of the thermal modification of the basalt thread. With the help of infrared spectroscopy, it is shown that the synthesized polymer is fully identified with the spectral pattern characteristic of polyamide-6.
