THERMOPHYSICAL PROPERTIES OF PARA-AMINOAZOBENZENE-MODIFIED EPOXY MATRICES FOR PROTECTIVE COATINGS IN THE TRANSPORT INDUSTRY
Abstract
On the basis of tests of thermal properties of epoxy composites filled with modifier using modern research methods permissible limits of temperature, at which it is possible to implement the developed materials are established. The thermal expansion coefficient (α), heat resistance (T) and thermal of epoxy composites are investigated. We set the absolute values of the thermal expansion coefficient of materials which can be used in different temperature ranges. The method of differential thermal and thermogravimetric analysis studied the thermal stability of materials and structural characteristics as the temperature increases. It is found the formation of composite materials with enhanced thermal properties, it is advisable to use as a modifier in an amount of q = 1,0 %. This material is characterized by the highest activation energy, resistance to structural change at the highest temperatures and intense interaction of the functional groups of the filler with an epoxy oligomer with the structure formation at the molecular level, all of the materials.
