Resumen
This research is an innovation proposal for magnetic conditioning of the aqueous-based polychloroprene contact adhesive with the purpose of increasing the adherence capacity between the adhesive and the substrate. Today, the aqueous-based polychloroprene contact adhesive presents an adhesion capacity variation between 1.15 and up to 2.75 kgf/cm2. On the other hand, the solvent-based polychloroprene adhesives support average tensions of shearing of 3.8 kgf/cm2. To promote an increase in adhesion to the aqueous-based polychloroprene contact adhesive, we formulated one adhesive using a nano-additive, carbon dioxide as catalyst, and a magnetic conditioning process before the phase of application on the substrates. The results obtained show an average increase of 292% in the shearing tension of the adhesive magnetically conditioned when compared with an adhesive of same formulation without the magnetic conditioning and when compared to the commercial aqueous-based polichloroprene adhesive, the increase reaches 122%.
