“…It is also a known fact that these materials are used as fillers and additives in the polymer sector. 23,24 According to a study of ªaban et al carried out in 2014, they proved that wood ash could be used as an effective filler material in polymer materials. 25 It should be noted that our natural resources are not infinite, that every source of production is reduced and that our natural resources are completely lost if they are carelessly used.…”

In this study, the effect of adding wood ash (oak tree) on the mechanical properties (tensile, abrasion, tearing, elongation %, etc.) of NR/SBR-type elastomer materials was investigated. Five different compounds were prepared by adding 16 %, 32 %, 48 % and 64 % wood ash to the filler and additive materials in the general composition (G). The mechanical test results and production costs of the new compounds composed were compared between themselves and with the G compound. The fracture surfaces of the compounds as well as the shape and morphological distribution of the fillers in the rubber matrix were examined using a Scanning Electron Microscope (SEM). As a result of the experimental studies, it was found that the new compounds composed had an increased tensile and tearing strength, abrasion amounts, bending capability, unit elongation amounts and densities in comparison to the G compound. A decrease was observed in the hardness values and material costs (production cost) of the compounds. Keywords: compounds, mechanical properties, wood ash Avtorji opisujejo raziskavo vpliva dodatka lesnega pepela (hrasta) na mehanske lastnosti (natezne lastnosti, abrazija, trganje, raztezek v %, itd.) elastomerov tipa NR/SBR. Pripravili so pet razli~nih vrst zmesi z dodatkom (16, 32, 48 in 64) w/% lesnega pepela, ki so ga uporabili kot polnilni in dodajni material k osnovni sestavi (G; angl.: General). Rezultate mehanskih preizkusov in stro{ke izdelave novih zmesi so primerjali med seboj in z zmesjo osnovne sestave G. Prelomne povr{ine zmesi, kakor tudi morfolo{ko porazdelitev polnila v matrici iz gume so opazovali in analizirali s pomo~jo vrsti~nega elektronskega mikroskopa (SEM). Na osnovi analize eksperimentalnih rezultatov avtorji ugotavljajo, da imajo izdelane nove zmesi povi{ano natezno in stri`no trdnost, ve~jo odpornost proti abraziji in sposobnost upogibanja ter enovit raztezek v primerjavi z gumo osnovne sestave G. Ugotavljajo tudi, da se je zmanj{ala trdota zmesi ter da so se zni`ali stro{ki njihove izdelave. Klju~ne besede: gumijaste zmesi, mehanske lastnosti, lesni pepel

“…In the paper provided by El-Nashar et al (17) it was reported that modified phosphate pigments may act as a strong reinforcement for an elastomeric composite. Ahmed et al (18) reported that it is economically justified to create a core-shell pigment out of the previously studied phosphate pigments with zinc oxide. Generally, any substance contributing to both changing the absorbance in visiblelight spectrum and enhancing other properties of a final composite may find practical application in the industry.…”

Abstract:A study about the influence of the impartment of phthalocyanine pigments into elastomeric composites was conducted. Acrylonitrile-butadiene (NBR) and styrenebutadiene (SBR) rubbers crosslinked by either sulfur or dicumyl peroxide were filled with non-toxic flame retardants (Mg(OH) 2 or Al(OH) 3 ) and thermally stable pigments (zinc or chloroaluminum phthalocyanines). Determination of cross-linking degree, mechanical properties, aging coefficient, thermal analysis (TG, DTG, DTA) and flammability tests (oxygen index, combustion in air) were carried out. The addition of the pigments, apart from the impartment of blue or blue-green color to elastomeric composites, in numerous cases improved their mechanical properties, thermal stability, limited flammability and allowed obtaining self-extinguishing materials in atmospheric air.

“…Typically, the core is formed by an inert filler (limestone, kaolin) or aluminum or glass flakes. The core functions as the support carrying the chemically active layers, e.g., oxides, which proactively prevent corrosion of the paint substrate (Ahmed, Abdel-Fatah, & Youssef, 2012;Ahmed & El-Nashar, 2013;El-Sabbagh, Ahmed, & Ward, 2012).…”

The anticorrosion properties of paints containing mixed metal oxide-based pigments were examined. Spinels with the cation combinations Ti-Zn-Mg or Fe-ZnMg were synthesized. Core-shell pigments with zinc oxide and magnesium oxide layers were also prepared. The pigments were synthesized from the oxides or carbonates by the high-temperature solid-phase process. The anticorrosion and physico-mechanical properties of film of paints based on an alkyd resin modified with soy oil and containing the pigments at a volume concentration of 10% were investigated. The highest anticorrosion efficiency was observed with the ferrite-based pigments. The anticorrosion efficiency was found to increase with increasing Zn contents of the pigments.
