Pyrolysis of natural, butadiene, styrene–butadiene rubber and tyre components: Modelling kinetics and transport phenomena at different heating rates and formulations

The method for recycling of rubber of different composition in granular state by introducing them into the polymerization medium at the synthesis of butadiene-styrene rubber was considerd. It was shown that rubber made on basis of such rubber, exhibits better physical and mechanical properties than at introducing grinded vulcanizate at producing these mixtures on rolls as well as through rubbers thermomechanical regeneration.

Aggregate–binder adhesion is critical to the performance of asphalt mixtures. Recently, particle probe scanning force microscopes were created to measure the adhesion between aggregate minerals and various plain and modified binders at the microscale. In this study, statistical analyses were performed to evaluate comprehensively the effects of different factors on the aggregate–binder adhesion, including aggregate constituents, binder types, and modifier types. Average unit surface energy values were used to quantify the adhesion between aggregate minerals and various binders. Results showed that the alumina–binder pairs exhibited the greatest adhesion. For the control binder, the adhesion values increased as the weight percentages of styrene–butadiene–styrene, styrene–butadiene–rubber, and polyphosphoric acid increased. Adhesion differences between aggregate minerals and various plain and modified binders were observed by using particle probe scanning force microscopes.

In this research, the effect of adding a virgin Styrene Butadiene rubber (SBR) on the morphology and properties of Acrylonitrile Butadiene Styrene (ABS) waste plastic has been investigated. The blends were prepared by melting method and characterized by means of mechanical testing, Scanning Electron Microscopy (SEM), Thermogravimatric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The obtained results indicated that virgin SBR phase dispersed efficiently, effectively in the ABS matrix and impact strength along with thermal resistance of the blends significantly improved. Thus, investigated results in this work will open promising approach for recycling ABS waste plastic.
