Abstract
Compuestos termofusibles a base de polipirrol, procedimiento para su preparación y su utilización como adhesivo, constituidos por mezclas de polipirrol conductor, en una proporción comprendida entre el 0,1% y el 90% en peso y copolímero de etileno y acetato de vinilo (EVA) en una proporción, en peso, comprendida entre el 99,9% y el 10%. Estas composiciones tienen propiedades mecánicas y de adhesión comparables a las de los termofusibles convencionales presentando, además, un buen nivel de conductividad eléctrica, por lo que son indicadas para fabricar adhesivos conductores termofusibles para aplicaciones de blindaje a interferencias electromagnéticas. Los nuevos adhesivos son útiles para aplicaciones electrónicas y de telecomunicaciones donde el peso sea una limitación, tales como juntas sellantes conductoras para aparatos de telefonía móvil, ordenadores portátiles y buscapersonas; así como para apantallar elementos o partes que irradien o reciban energía electromagnética en exceso respectoa valores permitidos. De aplicación en adhesivos.Thermofusible compounds based on polypyrrole, a procedure for their preparation and use as an adhesive, consisting of mixtures of conductive polypyrrole, in a proportion between 0.1% and 90% by weight and copolymer of ethylene and vinyl acetate (EVA) ) in a proportion, by weight, between 99.9% and 10%. These compositions have mechanical and adhesion properties comparable to those of conventional hot melts, also presenting a good level of electrical conductivity, and are therefore suitable for manufacturing hot melt conductive adhesives for shielding applications to electromagnetic interference. The new adhesives are useful for electronic and telecommunications applications where the weight is a limitation, such as conductive sealant joints for mobile telephony devices, laptops and pagers; as well as to shield elements or parts that radiate or receive electromagnetic energy in excess of permitted values. Application in adhesives.
