The current investigation treats about the influence of waste fodder potato proteins (WFPP) recovered from the starch industry on the mechanical-properties of carboxylated acrylonitrile-butadiene rubber (XNBR). WFPP were characterized and used as a filler of the above mentioned XNBR rubber without or after blending with zinc oxide. The obtained rubber compounds were cured, and mechanical properties such as tensile strength, hardness, and cross-linking density were investigated. It was found that the introduction of WFPP previously blended with zinc oxide into rubber compound increases the cross-linking density of the obtained composites, compared with the vulcanizate without protein, which in turn increases the mechanical properties of the obtained vulcanizates. That occurs thanks to the formation of ion nodes, as testified by equilibrium swelling. The introduction of WFPP into the elastomer matrix also increases the susceptibility of the elastomer to biodecomposition.

Positive Effect

The properties of rubber compounds and vulcanizates made using a compositional curing activator with a low content of zinc oxide were studied in this work. Technological modes of obtaining new curing activator activators in the form of an alloy of zinc oxide with a mixture of fatty acids have been developed. To give a convenient outlet shape, finely dispersed fillers of various types were introduced into the experimental products: silicon dioxide, carbon black, microcellulose, bentonite, shungite. The physicochemical properties of compositional curing activator were studied and it was established that, according to the values of acid and iodine numbers, the experimental products satisfy the regulatory requirements for stearic acid. A comparative analysis of the properties of elastomers of experimental products with widely used as curing activator activators of zinc oxide and stearic acid is carried out. It was found that the use of experimental products improves the processability of the compositions due to their better dispersion in an elastomeric medium. The ratios of the compositional curing activator components are determined, which ensure the optimal complex of vulcanization and physical and mechanical properties of elastomers made on their basis. The effectiveness of the action of composite vulcanization activator in the manufacture of elastomeric products is shown - a reduction in the mixing cycle of experimental compositions by an average of 10% is noted compared to the standard rubber compound. The analysis of the research results confirmed the improvement of technological and vulcanization properties of rubber compounds, resistance to scorching. It is shown that the use of compositional curing activators provides the required level of physical and mechanical properties of rubbers even with a decrease in the content of zinc oxide in the experimental product to 20 wt%, and also improves the dispersion of the components of the rubber compound, having a positive effect on the technological and vulcanization properties of rubber compounds.

Abstract The aim of this work was to examine the influence of new curing agents proposed for brominated butyl rubber (BIIR) on the cross-linking process of rubber compounds and the thermal behavior of the vulcanizates. Rubber blends that were filled with carbon black and contained acetylacetonates of different transition metals in the presence of triethanolamine (TEOA) as new cross-linking agents were prepared. The performed studies showed that metal acetylacetonates (Me(acac)) are effective cross-linking agents for BIIR, which was confirmed by high values of the torque increment (∆M) and significant cross-linking degree of the vulcanizates (α(T)). The most active curing agent seems to be iron acetylacetonate (Fe(acac)). Its application results in a shorter optimal vulcanization time, lower onset vulcanization temperature and similar vulcanization enthalpy compared to the BIIR cured with a sulfur curing system. The BIIR vulcanizates cured with Me(acac) reveal good mechanical properties with tensile strengths in the range of 9–14 MPa and better damping properties comparing to the sulfur-cured rubber. The proposed curing agents do not significantly affect the thermal stability of the BIIR vulcanizates.

Successful Technique

Abstract Thermal analysis provides a successful technique for the characterization and identification of rubber compounds. In this study, TGA (thermogravimetric analysis) and DTG (TGA derivative) profiles are used to predict and define the physico-mechanical properties of natural rubber — butadiene rubber (NR / BR) blends, using their thermal behaviors. DTG curves of vulcanizate showed that the initial degradation temperature of NR is lower than BR. According to TGA-DTG profiles we have demonstrated two useful factors, ΔTmax (Tmax BR100−Tmax BRX) and peak height ratio of NR-BR blends which are correlated with physico-mechanical properties of blends.
