ESTUDIO DE LA PINTABILIDAD DE PELÍCULAS DE NANOCOMPUESTOS POLIPROPILENO/TALCO

Abstract

En este trabajo se propone la inclusión de partículas minerales en películas a base de polipropileno (PP) para incrementar su pintabilidad. Para tales efectos, se aplicaron diferentes clases de pinturas comerciales en aerosol sobre películas de nanocompuestos a base de PP conteniendo 0, 1 y 5% p/p de talco. El grado de cubrimiento y homogeneidad de las pinturas sobre las películas se observó mediante microscopía óptica, en tanto que la adhesión de la pintura a la superficie polimérica se evaluó mediante ensayos bajo norma ASTM. De todas las pinturas analizadas, los mejores resultados de adhesión se obtuvieron con los aerosoles para plásticos y acrílicos. Sin embargo, la presencia de las nanopartículas de talco indujo mejoras en la adhesión pintura-película para el caso de los aerosoles que no son apropiados para aplicar sobre superficies plásticas, tal es el caso de los de secado rápido y para melamina.

In this work the incorporation of mineral particles in films based on polypropylene (PP) to increase their paintability, is proposed. For this purpose, several kinds of commercial spray paints were applied on nanocomposite films based on PP containing 0, 1 and 5% w/w of talc. The coating degree and homogeneity of the paints on the films was observed by optical microscopy, meanwhile the paint adhesion to the polymeric surface was evaluated using ASTM standard tests. From all analyzed paints, the best adhesion results were obtained with sprays for plastics and acrylics. However, the presence of talc nanoparticles induced improvements on paint-film adhesion for spray paints that are not suitable for application on plastic surfaces, such as quick dry and melamine paints.
