Abstract (EN):
This paper aims to analyze the peel strength of an adhesive joint with various types
of surface treatments. In the shoe industry, the adhesive properties are very important to ensure the quality of manufacture of the shoe, thus, to better understand the
behaviour of the adhesive joint, it is important to analyze the peel resistance in order
to adjust the manufacturing process. In this work, natural leather, thermoplastic rubber (TR) and a non-structural, solvent based, polyurethane adhesive were considered. The influence of the application of chemical and/or mechanical surface treatments on substrates in the peel strength of a T joint were analysed. To characterize
the surfaces, several test were considered, including Fourier Transform Infrared
Spectroscopy (FTIR), Scanning Electron Microscope (SEM) and contact angle
measurements. It was found that certain surface treatments are required to obtain
an adhesive joint capable of satisfying the minimum strength requirements of the
shoes sector.
