EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION

De forma concreta, lo que la invención propone es un producto en forma de resina fotopolimerizable mediante el cual se produce, con la acción de la luz y el contacto con los plásticos deteriorados, una reacción de polimerización molecular en varias dimensiones que regenera, mediante la formación de una película estable y homogénea, la capa exterior de dichos materiales plásticos, dándoles el aspecto de nuevos y con más intensidad en el color y brillo. Specifically, what the invention proposes is a product in the form of a photopolymerizable resin by means of which, with the action of light and contact with deteriorated plastics, a molecular polymerization reaction in several dimensions is regenerated which regenerates, by means of formation of a stable and homogeneous film, the outer layer of said plastic materials, giving them the appearance of new and with more intensity in color and brightness.

En una primera realización del producto objeto de la invención, la película que genera es transparente, sin pigmentos, y se aplica directamente sobre la superficie, la cual deberá estar limpia de suciedad y polvo y completamente seca, para que la adherencia y agarre del producto sobre la superficie sea efectiva. Esta variante del producto está encaminada para ser utilizada en aquellos plásticos rígidos que, estando deteriorados por la luz del sol y efectos climatológicos, aún tienen propiedades de pigmentación y únicamente han perdido intensidad de color y brillo. In a first embodiment of the product object of the invention, the film it generates is transparent, without pigments, and is applied directly on the surface, which must be clean of dirt and dust and completely dry, so that the adhesion and grip of the product on the surface be effective. This product variant is intended to be used in those rigid plastics that, being damaged by sunlight and weather effects, still have pigmentation properties and have only lost color intensity and brightness.

El modo de uso del producto descrito será el siguiente: The way of using the product described will be the following:

Primero, se procede a la limpieza y preparación de la superficie a tratar, con un producto desengrasante puro o diluido en agua, en función de la intensidad de la suciedad, preferentemente con mochila de fumigación o similar. Se deja actuar unos minutos (entre 5 y 10) y si fuera necesario, en función de la suciedad que presente la superficie, se puede frotar con un cepillo o simplemente aclarar. Se mejora el resultado con la utilización de agua caliente y, si la superficie está muy sucia, se recomienda repetir la operación. First, we proceed to the cleaning and preparation of the surface to be treated, with a pure degreasing product or diluted in water, depending on the intensity of the dirt, preferably with a spray bag or similar. Leave on for a few minutes (between 5 and 10) and if necessary, depending on the dirt on the surface, it can be rubbed with a brush or simply rinse. The result is improved with the use of hot water and, if the surface is very dirty, it is recommended to repeat the operation.

Posteriormente, y habiendo dejado secar completamente la superficie tras su limpieza, siendo importante que esté bien seca, se procede a aplicar el producto renovador-recuperador de plásticos rígidos objeto de la invención, para conseguir la recuperación de la superficie mediante la polimerización dicho producto sobre ella. Para ello, se aplica el producto puro, es decir, tal y como se suministra sin diluir, por pulverización con mochila de fumigación o similar, impregnando la superficie y dejando actuar entre 5 y 10 minutos. Si fuera necesario, se repite la operación y se dejan otros 5 a 10 minutos. El excedente de producto se retira con un paño de algodón que no suelte pelusa ni pelos, pudiendo utilizarse así mismo un rodillo de lacar, para realizar dicha retirada del exceso de producto y extenderlo y unificarlo. Luego se deja secar de seis a ocho horas y ya queda listo. Subsequently, and having allowed the surface to dry completely after cleaning, it is important that it be very dry, the renovator-recovery product of rigid plastics object of the invention is applied, to achieve surface recovery by polymerization said product on she. For this, the pure product is applied, that is, as it is supplied undiluted, by spraying with a spray bag or similar, impregnating the surface and allowing it to act for 5 to 10 minutes. If necessary, the operation is repeated and another 5 to 10 minutes are left. The surplus of the product is removed with a cotton cloth that does not release lint or hair, and a lacquer roller can also be used to perform said removal of the excess product and spread and unify it. Then let it dry for six to eight hours and it is ready.

La invención contempla, además, una segunda variante de realización del producto renovadorrecuperador de plásticos rígidos que incorpora pigmentos y que está pensado para utilizarse en aquellos plásticos rígidos que, estando deteriorados por la luz del sol y los efectos climatológicos, sus pigmentos se han degradado mucho o no existen y, además, han perdido intensidad de brillo, es decir, la capa superficial del material plástico se encuentra tan deteriorada que no tiene ni brillo ni pigmentación. The invention also contemplates a second variant of the renovation product recovery of rigid plastics that incorporates pigments and is intended for use in those rigid plastics that, being damaged by sunlight and weather effects, their pigments have greatly degraded or they do not exist and, in addition, they have lost brightness intensity, that is, the surface layer of the plastic material is so deteriorated that it has neither shine nor pigmentation.

En este segundo caso, y para disolver el pigmento, se hace necesario incorporar un aditivo disolvente que lo solubilice y un fotopolimerizador que active el proceso de polimerización y lo acelere. In this second case, and to dissolve the pigment, it is necessary to incorporate a solvent additive that solubilizes it and a photopolymerizer that activates the polymerization process and accelerates it.

La composición del producto, en esta segunda variante de realización es, pues, la misma que la anterior, pero incorporando pigmentos (rojo, blanco, azul, amarillo, verde, negro, etc.), preferentemente según carta de colores RAL, así como un segundo componente fotoiniciador que se mezcla en el momento de uso. The composition of the product, in this second variant, is therefore the same as the previous one, but incorporating pigments (red, white, blue, yellow, green, black, etc.), preferably according to RAL color chart, as well as a second photoinitiator component that is mixed at the time of use.

En concreto, dicho segundo componente fotoiniciador comprende las siguientes sustancias, detalladas con el tanto por ciento en peso preferente de cada una: Specifically, said second photoinitiator component comprises the following substances, detailed with the preferred weight percent of each:

--: Peróxido de metil-etil cetona 35,0000 Methyl Ethyl Ketone Peroxide 35,0000

--: Ftalato de dimetilo 60,0000 Dimethyl Phthalate 60,0000

--: Metil-Etil-Cetona 5,0000 Methyl Ethyl Ketone 5,0000

En este caso, el modo de uso es el mismo que el anterior en la primera parte de limpieza y preparación de la superficie. Sin embargo, para la aplicación propiamente dicha del producto, como ya se ha señalado, se mezcla el producto inicial o resina fotopolimerizable pigmentada con el componente fotoiniciador que se mezcla en una proporción de un 2% a un 2,5%, sobre el total del producto. In this case, the mode of use is the same as the previous one in the first part of cleaning and surface preparation. However, for the actual application of the product, as already indicated, the initial product or pigmented photopolymerizable resin is mixed with the photoinitiator component that is mixed in a proportion of 2% to 2.5%, over the total of the product.

Conviene señalar que se debe preparar la cantidad que se vaya a utilizar poco a poco, ya que, transcurridos unos 25 minutos, endurece y no se puede extender. It should be noted that the amount to be used should be prepared little by little, since, after about 25 minutes, it hardens and cannot be extended.

Esta segunda variante del producto de la invención, una vez mezclada, se aplica por pulverización, con pistola de presión o equipo de pintura similar, impregnando la superficie y dejando actuar unas 2 ó 3 horas. Se repite la operación si fuera necesaria una segunda mano, y se deja secar. This second variant of the product of the invention, once mixed, is applied by spraying, with a pressure gun or similar painting equipment, impregnating the surface and allowing to act for 2 or 3 hours. The operation is repeated if a second hand is necessary, and allowed to dry.

En este caso conviene procurar que no exista exceso de producto, para que no chorree y se formen marcas. Además, en este caso, no se puede pasar ningún paño, ya que el acabado del color sería defectuoso. In this case it is advisable to ensure that there is no excess of product, so that it does not drip and marks are formed. In addition, in this case, no cloth can be passed, since the color finish would be defective.

Se deja secar un mínimo de 8 horas y el objeto reparado (silla, etc.) se puede utilizar al partir de 5 las 24 a 48 horas. A minimum of 8 hours is allowed to dry and the repaired object (chair, etc.) can be used after 5 to 24 to 48 hours.

En ambos casos, es importante que no haya humedad ni polvo o suciedad, tal como sucede con la aplicación de cualquier pintura normal. Además, es aconsejable realizar la aplicación a la luz del sol para acelerar la polimerización, si bien, no es aconsejable que se alcancen elevadas temperaturas, ya que ello puede ser contraproducente para una buena adherencia del producto sobre la superficie a reparar. In both cases, it is important that there is no moisture or dust or dirt, as with the application of any normal paint. In addition, it is advisable to apply it to sunlight to accelerate polymerization, although it is not advisable to reach high temperatures, since this can be counterproductive for good adhesion of the product on the surface to be repaired.
