METHOD OF ACCELERATED OBTAINING ARTICLES ON BASE OF EPOXY ADHESIVE COMPOSITIONS CONTAINING PLASTICIZER, USING ULTRASOUND

摘要

A method of accelerated obtaining articles on the base of epoxy adhesive compositions containing a plasticizer, using ultrasound includes ultrasonic treatment of liquid epoxy compositions, their mixing with a plasticizer and a hardener followed by measuring the total duration of obtaining a fully solidified article based on the compositions. Then the ultrasonic treatment of the mixture of resin parts of composition weighing (0.4-0.45) kg is carried out prior to mixing them with a hardener at a frequency of (15-20) kHz, amplitude (4-10) μm, intensity (5-10) W/cm, temperature (55-70) °C within (25-30) min. under the normal pressure.
