FIELD: chemistry.
SUBSTANCE: epoxy resin ED-20 is first mixed with carboxylated rubber SKD-KTRA in a closed mechanical mixer. Final mixing of components in the composition is carried out in a rotary-oscillatory apparatus in self-oscillation mode while monitoring onset of final mixing indicated by power input switching to stationary mode and fluctuation thereof ceasing. Characteristics of the epoxy-rubber composition: for 50% rubber content - breaking strength of 16.9 MPa, relative elongation - 70.2%, adhesion strength - 16.2 MPa.
EFFECT: high-quality end product with improved physical and mechanical properties.
