Tratamiento mediante plasma para la mejora de propiedades en sustratos poliméricos en juguetes, plásticos y textiles

Revista de plásticos modernos: Ciencia y tecnología de polímeros (2011)

J de Teresa Galván Ana Ibáñez Asunción Martínez-Martínez Óscar Calvo M. Carmen Davó Blanes

espanolEl tratamiento de superficies mediante tecnologias de plasma permite, utilizando tecnologias limpias, la optimizacion de las prestaciones adhesivas, asi como el incremento de la solidez en pinturas y recubrimientos o la funcion de propiedades barrera como repelencia a liquidos. Podrian, asimismo, permitir la aplicacion de recubrimientos metalizados a materiales polimericos. Los centros tecnologicos AIJU y AITEX colaboran en un proyecto de especial relevancia en el que participan diez empresas y liderado por la empresa juguetera INJUSA, para la investigacion de los distintos procesos de plasma en funcion de las propiedades deseables y su campo de aplicacion. EnglishThe surface treatment by means of plasma technologies allows for, using clean technologies, the optimization of the adhesion characteristics as well as the increase in solidness of paints and coatings, or barrier function properties, such as repellent to liquids. They could even allow the application of metalized coatings to polymeric materials. The technological centres AIJU and AITEX are actively collaborating on this project of special relevante in which ten companies, lead by the toy company INJUSA, pariicipate for the research of distinct plasma processes with regards to the intended properties and their field of application.

Surface Modification of a Polyurethane Film by Low Pressure Nitrogen Plasma for Improved Adhesion to Polyethylene Foam for Automotive Industry Laminates

Plasma Processes and Polymers (2007)

M.R. Sanchis Óscar Calvo O. Fenollar David García Sanoguera R. Balart

A low pressure glow discharge nitrogen plasma has been used to modify wettability of a polyurethane film and, consequently, improve adhesion properties to polyolefin foam in order to obtain technical laminates for uses in automotive industry. A significant increase in surface wettability is achieved after the plasma treatment as observed by contact angle measurements. Surface changes have been studied by X-ray photoelectron spectroscopy (insertion of polar groups) and atomic force microscopy (changes in surface roughness and topography). Laminates based on plasma-treated polyurethane film and polyolefin foam show a considerable increase in the T-peel strength of the adhesion joint; furthermore we can observe a slight ageing process under aggressive conditions (high temperature and relative humidity).

Optimization of adhesive joints of low density polyethylene (LDPE) composite laminates with polyolefin foam using corona discharge plasma

Journal of Applied Polymer Science (2009)

PASCUAL Mónica Óscar Calvo Lourdes Sanchez‐Nácher Marilés Bonet-Aracil David García Sanoguera

Abstract In this work, surface modification of low density polyethylene (LDPE) film has been carried out to optimize adhesive joints with polyolefin foam for uses in technological applications. LDPE films were modified in a continuous way using corona discharge plasma with different powers, ranging from 200 to 600 W and several film advance rates in the 5–20 m min −1 range. Changes in surface wettability have been studied with contact angle measurements and subsequent solid surface energy calculation. A polyurethane adhesive was used to join the LDPE film to a polyethylene foam. Mechanical performance of the adhesive joints has been determined by T‐peel tests and also the aging effects of several hydrothermal conditions have been studied to evaluate the usefulness of these laminate composites in technological applications. Results show that corona discharge powers between 400 and 600 W are suitable in terms of wettability improvement; on other hand, a slight decrease in surface wettability as the film advance rate increases is detected but the overall changes as a consequence of the film advance rate in the 5–20 m min −1 range are small if compared to changes derived from working powers in the 200–600 W range. Adhesive joints offer excellent mechanical performance and good durability in hydrothermal conditions thus being appropriate for technical applications. © 2009 Wiley Periodicals, Inc.
