Repeatability of properties of compounds and vulcanizates of styrene-butadiene rubber containing pyrolytic carbon black obtained by pyrolysis of tyres

The paper presents the results of studies on the repeatability of properties of compounds and vulcanizates of styrene-butadiene rubber containing independent samples of pyrolytic carbon black. For comparison, analogous compounds and vulcanizates containing technical carbon black N550, N772 and kaolin were examined. It was found that pyrolytic carbon black gives the compounds high Mooney viscosity. The obtained viscosity values for the three carbon black tests are repeatable, within the range of ±5%. Compounds with pyrolytic carbon black samples have optimum vulcanization time (t90) values similar to those of compounds containing technical carbon black. The dispersion of the t90 values is greater and is ±14%. It was found that the more sulphur and zinc compounds containing pyrolytic carbon black, the higher the rate of vulcanization. Individual samples of pyrolytic carbon black give SBR vulcanizates a high and reproducible hardness equal to that of carbon black vulcanizate N550 and much higher than that of carbon black vulcanizate N772 or kaolin. Tensile strength at break (TSb) values of vulcanizates with pyrolytic carbon black samples are also repeatable, but much lower than those obtained for carbon black vulcanizate N550 and N772. Similarly, the abrasion resistance of vulcanizates with pyrolytic carbon black samples reaches similar values, but is significantly lower than that of vulcanizates with carbon black N550, N772, but higher than that of vulcanizates with kaolin. Pyrolytic carbon black has unfavourable features which weaken the possible amplifying effect resulting from the relatively high iodine value (approx. 50 g/kg). These can be: the presence of a significant amount of mineral parts, insufficient fineness of carbon black particles, altered surface structure of primary carbon black particles or the presence of heavy pyrolytic oils and oligomeric rubber substances resulting from pyrolysis process.

Thermoplastic bio-polyurethane elastomers synthesized with two bio-based monomers

The aim of this work was to investigate the influence of renewable origin monomers on selected properties of new thermoplastic polyurethane elastomers. Materials were synthesized by a prepolymer method with using petrochemical diisocyanate and two bio-based monomers: bio-polyol and bio-glycol. The effect of molar ratio of isocyanate [NCO] to hydroxyl [OH] groups during extension of the urethane prepolymer chains on the selected properties of prepared materials was also investigated. The chemical structure of the obtained bio-polyurethanes was confirmed by the FTIR-ATR technique. The influence of molar ratio [NCO]/[OH] on the mechanical properties (i.e. tensile properties, hardness), and dynamic mechanical properties (storage modulus, loss modulus and damping factor) of produced polyurethanes was examined.

Effect of thermo-oxidative ageing on mechanical properties of elastomeric nanocomposites reinforced by carbon nanotubes

This paper presents the results of the studies on thermo-oxidative stability and the influence of thermo-oxidative ageing on the molecular mass and mechanical properties of nanocomposites based on copoly(ether-ester) elastomer filled with non-functionalized and functionalized by -COOH groups multi-wall carbon nanotubes (MWCNT, MWCNT-COOH). The multiblock poly(ether-ester) copolymer used as a polymer matrix in investigated nanocomposites was composed of rigid poly(trimethylene terephthalate) (PTT) blocks and flexible poly(tetramethylene oxide) (PTMO) blocks. The effect of nanotubes contribution on thermal and thermo-oxidative stability was evaluated by thermogravimetric analysis. The influence of the aging time at the elevated temperature on the copolymer molecular mass and mechanical properties of the tested nanocomposites and unfilled PTT-PTMO copolymer was investigated.
It was found that the presence of carbon nanotubes improves the thermal and thermo-oxidative stability of the PTT-PTMO copolymer, as well as increases the resistance to thermo-oxidative ageing of the obtained nanocomposites.
