Determination of the main parameters of the modified epoxide oligomer

In order to obtain a high-quality composite material based on the epoxy oligomer that meets the requirements of the operating conditions, research works were carried out in this direction in the dissertation work on obtaining compositions with new quality modified properties based on the modification of the epoxide oligomer with various oligomers. Therefore, ED-20 / MFFO-96/4, ED-20 / SKN-18-1-96/4, ED-20 / MFFO / SKN-18-1-96/2/2, MFFO, SKN-18-1, MFFO / SKN-18-1 and MFFO / . Highly filled compositions based on butadiene-nitrile rubber modified with SKN-18-1 / ED-20 oligomer and oligomer mixtures were prepared and their properties were studied. A number of properties of these obtained adhesive compositions have increased compared to the properties of the composition obtained on the basis of ED-20. For example, strength limit at the moment of breaking, strength of contact with metal on tearing, strength of contact with metal on sliding, strength of contact with wood, resistance to aggressive environments, etc. The influence of fillers (ZnO and dolomite) on the physico-mechanical properties of adhesive compositions was studied and their optimal amounts were determined. It was found that ZnO has a more effective effect than dolomite.
