“…Infra-red spectroscopy: With Infra-red spectroscopy technique it is possible to identify chemical modifications in a polymeric material. Oxidation products, from polymers degradation, subjected to FTIR, present spectral bands within 1,820 to 1,630 cm -1 , corresponding to carbonyl groups (C=O) from various types of organic functions: ketones, aldehydes, carboxylic acids and esters [10].…”

In order to minimize impacts caused to environment and to save natural resources, especially from non-renewable sources, recycling of polymeric materials has been object of study. In this scenery, are included elastomeric materials, such as rubber, especially used in tires manufacturing, considering that pneumatic industry consumes around 60% of rubber production. Taking into account that final tires destination is a requirement based on norms and national and international laws, this work aims to the development of a study on the efficacy of micro-wave irradiation in the process of de-vulcanization of tire powder to be used in recycling. Tire powder was subjected to micro-wave irradiation and further merged to SBR (butadiene-styrene rubber) polymeric matrix, at 5, 15, 25 phr; after mixture, resulting compound was characterized for evaluation of physico-chemical and mechanical properties. For the assessment of all samples containing SBR and rubber powder there were applied following essays: Infra-red spectroscopy (FTIR), Tensile strength and elongation at break, Swelling Index. It was verified higher values for mechanical properties imparted by an increased quantity of rubber powder incorporated to SBR matrix.

The recycling of polymeric materials has been studied in order to save natural resources, mainly from non-renewable sources, in order to minimize the impacts caused to the environment. In this scenario, there are elastomeric materials, such as rubber, mainly used in tire manufacturing, since the pneumatic industry consumes approximately 60% of rubber production. As the final destination of an environmentally correct tire is a requirement, duly supported by national and international laws and regulations, the objective of this work is to develop a study on the efficiency of microwave irradiation in the process of tire powder devulcanization. For this study the tire powder samples were subjected to microwave irradiation, and later incorporated into the polymer matrices of NR (natural rubber) and SBR (butadiene-styrene rubber), and characterized for verification of their properties. For characterization of the samples the following tests were used: Infrared Spectroscopy (FTIR), Hardness, Tensile Strength and Stretching, Rheometry, Swell Index, Thermogravimetric Analysis (TGA) and Scanning Electron Microscopy (MEV). It was verified the technical feasibility of the incorporation of the tire powder in the NR and SBR matrices, since some results showed that the addition of the tire powder irradiated by microwave did not cause significant losses in the mechanical and thermal properties of the compounds.
