Polymer composites for improving the resource of pipeline transport
Keywords:activity of the filler, adhesion strength, cohesive strength, fracture structure, IR-spectral analysis, optical microscopy.
Epoxy-composite protective coatings filled with anti-agglomerating additive have been investigated using IR-spectral
analysis. The presence of O-H and C-H bonds in the range of wave numbers ν = 2848–2922 cm-1, C-C in the range of wave
numbers ν = 1112–1541 cm-1 and the amino groups in the range of wave numbers ν = 623–667 cm-1, indicating the catalytic
activity of the additive. It has been established that it is expedient to use an additive for the contents of q = 20 pts.wt. for the
formation of the adhesive layer of coating, while there was observed the maximum growth of adhesion strength. Then, as for the
formation of a coating with high cohesive strength, it is advisable to use an additive containing q = 10–20 pts.wt., which provides
both elastic properties and moderate stiffness of the epoxy composite material. By the method of optical microscopy there is
analyzed the structure of epoxy composites and determined the optimum content of the filler with the ordered structure, without
defects, which provides high indicators of cohesive strength of materials.
