Abstract
Los oscurecimientos de frita de esmalte negro son serigrafiados comúnmente en vidrios laminados y templados de seguridad automotriz, los cuales sirven para ocultar el adhesivo utilizado para unir el laminado al cuerpo del automóvil y para proteger el adhesivo de la radiación ultravioleta. Sin embargo, la frita tiene una serie de inconvenientes. La frita debilita la superficie del vidrio. Puede crear distorsión en el vidrio debido a gradientes térmicos. Los oscurecimientos de frita serigrafiada son incompatibles y no se pueden usar con muchos tipos de recubrimientos. La frita estándar bloquea el intercambio iónico y no se puede usar con el proceso de templado químico. Además, aunque existen muchos tipos de fritas disponibles que pueden ser serigrafiados en vidrio de cal sodada, existen muy pocas, si es que las hubiera, para el vidrio que no posee cal sodada. A medida que el mercado avanza hacia laminados más delgados y livianos, los tipos de vidrio que no poseen cal sodada encuentran cada vez más aplicaciones en laminados automotrices. Estas limitaciones se superan mediante la sustitución del oscurecimiento de frita negra serigrafiada con un oscurecimiento formado a partir de una lámina delgada de plástico, que se integra en el laminado.Black enamel frit darkenings are commonly screen printed on laminated and tempered automotive safety glass, which are used to hide the adhesive used to bond the laminate to the car body and to protect the adhesive from ultraviolet radiation. However, the frit has a number of drawbacks. The frit weakens the surface of the glass. It can create distortion in the glass due to thermal gradients. Screen darkening fritters are incompatible and cannot be used with many types of coatings. The standard frit blocks the ion exchange and cannot be used with the chemical tempering process. In addition, although there are many types of frits available that can be screen printed on soda lime glass, there are very few, if any, for glass that does not have soda lime. As the market moves towards thinner and lighter laminates, glass types that do not have soda lime are increasingly finding applications in automotive laminates. These limitations are overcome by replacing the darkening of black silk screen printed with a darkening formed from a thin sheet of plastic, which is integrated into the laminate.
