Abstract
The influence of additives of nanofillers containing nanoparticles of copper oxides stabilized by a polymer matrix of maleinized high-pressure polyethylene obtained by the mechano-chemical method on the structure and properties features of metal-containing nanocomposites based on isotactic polypropylene and butadiene-nitrile rubber by x-ray phase and differential thermal analyses is studied. The improvement of strength, deformation and rheological parameters, as well as thermal-oxidative stability of the obtained nanocomposites was revealed, that is probably due to the synergistic effect of interaction of copper-containing nanoparticles with maleic groups of maleinated high-pressure polyethylene. It is shown that nanocomposites based on isotactic polypropylene and butadiene-nitrile rubber can be processed both by pressing method and by injection molding and extrusion methods that expands the scope of its application
Highlights
The current stage in the development of chemistry and technology of composite materials is largely determined by the search for ways to create materials with an improved set of properties
We studied the effect of small NF additives containing NP of metal oxides on the properties of mixed thermoplastic elastomers (TPE) based on isotactic PP and butadiene nitrile rubber (BNR)
The introduction of 0.3–0.5 mass % NF into the composition leads to an increase in the strain upon rupture of the composite by 1.25–1.5 times, which, apparently, is due to the synergistic effect associated with the presence of copper-containing nanoparticles in the maleinized high-pressure polyethylene (MPE) matrix containing maleic groups, the mutual influence of which contributes to an increases in both the deformation value and the strength index
Summary
The current stage in the development of chemistry and technology of composite materials is largely determined by the search for ways to create materials with an improved set of properties. Intensive development of the global petrochemical industry requires a constant search for new materials with high consumer properties, environmental safety and ease of processing Such materials, not without reason, are thermoplastic elastomers (TPE). Due to the complex of high physical and mechanical properties, a wide temperature range of operability, lower cost of end products, TPV are considered one of the most promising classes of polymer composite materials. The areas of their application are very diverse [3, 4].
