Incorporação de resíduos de calçados (SBR) na produção de compósitos leves.

Abstract

The increase in production indicators of the industrial sector is an important factor for the development of a region. In contrast, the generation of waste, is a consequence of that growth,resulting in high rates of environmental liabilities, in many cases difficult to answer. The final disposal of industrial waste into the environment or to burning are not ideal solutions. It is known that the waste from the production process footwear as EVA, PU, PVC, not vulcanized rubber, thermoplastic rubber (TR), natural rubber and thermoplastic polyurethane have good chances of being employed in construction, such as synthetic aggregate in place for households membership of composites in natural light cimentícios. In Paraíba, you can see that the generation of waste from the footwear segment has grown significantly and that is proportional to the economic growth of the sector, thus contributing to the increase in the indicators. The recovery of waste produced by the footwear industry through the manufacture of plates, and reinforcement of cementitious matrix polymer, for application as divisive, fascia, eaves, thermal and acoustic insulation, among others has been set up as a potential alternative to the researchers in framework of technological innovation and has been the subject of recent research. Therefore, this study aimed to, deepen the knowledge developed in the manufacture of wafers, from research, analysis, physical and mechanical tests, referrals and previous results showing the technique's viability as constructive unconventional material. The products available in the market served as a comparison to the alternative product produced, slabs of concrete light-based cementitious (Useplac, Useploc, Brasiplac, Isoplac), plates made with Styrofoam and plaster, among others. It was found through analysis, physical and mechanical tests, that the composite material and reinforcement of cementitious matrix polymer (SBR) is technically feasible. The modules of rupture (MOR) and the compression of such material was consistent with the established minimum resistance and validated in the market for similar products, for use as a constructive non-structural, fireproof, resistant to temperatures between 200 and 800ºC and with high capacity water absorption. When subjected to pressure from low energy, the composite showed excellent degree of sealing, lower porosity and resistivity and better ductility.
