Pasta pigmentaria aplicable en recubrimientos y metodo para su fabrication.Pigment paste applicable in coatings and method for manufacturing.
Objeto de la invention.Object of the invention.
El objeto de la presente invention es una pasta pigmentaria aplicable en recubrimientos, que comprende. pigmentos, dispersantes, resina filmogena y disolventes; as! como a un metodo para su fabricacion.The object of the present invention is a pigment paste applicable in coatings, which it comprises. pigments, dispersants, filmogenic resin and solvents; ace! as to a method for its manufacture.
Esta invention presenta unas caracterlsticas orientadas a conseguir una pasta pigmentaria con un grado de finura o tamano de partlcula inferior a una micra.This invention has characteristics aimed at achieving a pigment paste with a degree of fineness or particle size of less than one micron.
Estado de la tecnica.State of the art.
Actualmente es conocido en el mercado la existencia de pastas pigmentarias destinadas a las industrias de recubrimientos, entendiendo como tales los productos llquidos aplicables a un soporte de cualquier tipo y que por secado, reticulation, o cualquier otro sistema se convierten en una pellcula o capa seca fuertemente adherida al soporte en cuestion.At the moment the existence of pigmentary pastes destined to the coatings industries is known in the market, understanding as such the liquid products applicable to a support of any type and that by drying, reticulation, or any other system become a film or dry layer strongly attached to the support in question.
Tambien es conocida la obtencion de estas pastas pigmentarias mediante la dispersion de los pigmentos en maquinas de molienda-dispersion, por ejemplo monocillndricas, tricillndricas, o molinos de bolas ceramicas.It is also known to obtain these pigment pastes by dispersing the pigments in grinding-dispersing machines, for example, monocillndricas, tricillndricas, or ceramic ball mills.
Los equipos y tecnicas utilizadas permiten obtener pastas pigmentarias con un grado de finura o tamano de partlcula comprendido entre 5 y 25 micrasThe equipment and techniques used make it possible to obtain pigment pastes with a fineness or particle size between 5 and 25 microns
Los pigmentos estan conformados por productos insolubles, organicos e inorganicos, usados para cubrir la superficie aplicada cambiando su color, aspecto y acabado.The pigments are made up of insoluble, organic and inorganic products, used to cover the applied surface by changing its color, appearance and finish.
Cabe mencionar que los pigmentos tienen un tamano de partlculas muy variable, y no pueden usarse sin una dispersion previa, ya que se obtendrla una capa heterogenea, rugosa y con un aspecto final que no cumplirla los mlnimos requisitos de calidad.It should be mentioned that the pigments have a very variable particle size, and cannot be used without a previous dispersion, since a heterogeneous, rough layer with a final appearance will be obtained that does not meet the minimum quality requirements.
Un objetivo de los fabricantes de estas pastas pigmentarias es mejorar el rendimiento colorlstico y la calidad del acabado, desconociendo el solicitante de la presente invention la existencia en el mercado de pastas pigmentarias que proporcionen un acabado y una calidad mayor a la conseguida con las tecnicas de dispersion empleadas anteriormente y en las que las pastas pigmentarias alcanzan un grado de finura entre 5 y 25 micras.An objective of the manufacturers of these pigment pastes is to improve the color yield and the quality of the finish, the applicant of the present invention being unaware of the existence in the market of pigment pastes that provide a finish and a quality greater than that achieved with the techniques of dispersion used previously and in which pigment pastes reach a fineness between 5 and 25 microns.
Description de la invention.Description of the invention.
La pasta pigmentaria objeto de esta invencion, siendo aplicable en recubrimientos, y comprendiendo en su composicion pigmentos insolubles, agentes dispersantes, resina filmogena y disolventes; presenta unas caracterlsticas orientadas a resolver los problemas mencionados anteriormente y concretamente a obtener un grado de dispersion de los pigmentos que proporciona unos efectos sorprendentes en lo que se refiere al rendimiento colorlstico y a la calidad de los acabados de los recubrimientos.The pigment paste object of this invention, being applicable in coatings, and comprising in its composition insoluble pigments, dispersing agents, filmogenic resin and solvents; It presents some characteristics oriented to solve the problems mentioned above and specifically to obtain a degree of dispersion of the pigments that provides surprising effects in terms of color performance and the quality of the coatings finishes.
La pasta pigmentaria de la invention, comprendiendo en su composition los elementos mencionados anteriormente es decir: pigmentos insolubles, agentes dispersantes, resina filmogena y disolventes presenta la particularidad de estar constituida por una nanodispersion de los pigmentos insolubles en los componentes indicados, presentando la pasta pigmentaria un grado de finura o tamano de partlcula inferior a 1 micra.The pigment paste of the invention, comprising in its composition the elements mentioned above that is to say: insoluble pigments, dispersing agents, filmogenic resin and solvents has the particularity of being constituted by a nanodispersion of the insoluble pigments in the indicated components, presenting the pigment paste a degree of fineness or particle size less than 1 micron.

Este grado de dispersion y tamano de los pigmentos insolubles, inferior a 1 micra proporciona unas mejoras sorprendentes respecto a los productos tradicionales, siendo de destacar:This degree of dispersion and size of insoluble pigments, less than 1 micron, provides surprising improvements over traditional products, the most important being:
- Mejora del rendimiento colorlstico.- Color rendering improvement.
- Mejora de las propiedades de brillo y acabado.- Improvement of gloss and finish properties.
- Elimination de fenomeno de "rub out”, o cambio de color por roce en la pelicula humeda.- Elimination of "rub out" phenomenon, or change of color by rubbing on the wet film.
- Facilita la reproduction del producto en production, ya que el pigmento se encuentra en fase de total rendimiento.- It facilitates the reproduction of the product in production, since the pigment is in full performance phase.
- Elimina las tensiones internas en la capa de recubrimiento una vez seca, ya que no existen partlculas sobredimensionadas.- Eliminates internal stresses in the coating layer once dry, since there are no oversized particles.
- Aumenta la transparencia del pigmento, lograndose capas totalmente transparentes, similares a las obtenidas con colorantes, pero con las propiedades de resistencia de los pigmentos.- Increases the transparency of the pigment, achieving completely transparent layers, similar to those obtained with dyes, but with the resistance properties of the pigments.
La estabilidad de la pasta pigmentaria con este grado de dispersion de los pigmentos se consigue mediante el uso de agentes dispersantes, preferiblemente polimericos y de resinas filmogenas, preferentemente alquldicas o aldehldicas, compatibles con las formulaciones de los recubrimientos a fabricar.The stability of the pigment paste with this degree of dispersion of the pigments is achieved through the use of dispersing agents, preferably polymeric and filmogenic resins, preferably alkyd or aldehyde, compatible with the formulations of the coatings to be manufactured.
