Description

Procedimiento para flocado de perfiles y perfil flocado obtenido mediante el mismo.Profile and profile flocking procedure flocking obtained by it.

La presente invención está destinada a dar a conocer un procedimiento para el flocado de perfiles así como el perfil flocado obtenido mediante el mismo. Mediante el término flocado se hace referencia en diferentes sectores técnicos a una superficie de características aterciopeladas. En particular, la presente invención se refiere al sector de los perfiles hechos, principalmente, de goma.The present invention is intended to give know a procedure for profile flocking as well as the flocked profile obtained by it. Through the term flocking reference is made in different technical sectors to a surface velvety features. In particular, the This invention refers to the sector of the profiles made, Mainly rubber.

Dicho tipo de perfiles de goma, como por ejemplo EPDM (terpolímero de etileno-propileno-dieno no conjugado), flocados, son utilizados, por ejemplo, en el sector de la automoción, para la realización de juntas exteriores en las ventanas de cristal deslizante de los automóviles, dadas las excelente propiedades de resistencia a las condiciones atmosféricas de la goma EPDM. Dichos perfiles poseen una superficie aterciopelada, que recibe el nombre de superficie flocada, que tiene como función reducir el rozamiento del cristal con el perfil.Said type of rubber profiles, such as  EPDM (terpolymer of ethylene-propylene-diene no conjugated), flocked, are used, for example, in the sector of the automotive, for the realization of external joints in the sliding glass windows of cars, given the excellent weather resistance properties of the EPDM rubber. These profiles have a surface velvety, which is called flocked surface, which Its function is to reduce the friction of the glass with the profile.

El método hasta ahora conocido para el flocado en línea de superficies en perfiles de goma consiste en hacer pasar el perfil durante el proceso de extrusionado por una cabina o zona con temperatura y humedad controladas donde se aplica un adhesivo sobre la superficie del perfil a flocar y se procede a la posterior deposición del floc mediante campos electrostáticos. Después de salir de la cabina o zona de flocado, el perfil se introduce en un canal caliente u horno, para que polimerice por temperatura el adhesivo
utilizado.The method known so far for inline flocking of surfaces in rubber profiles is to pass the profile during the extrusion process through a cabin or zone with controlled temperature and humidity where an adhesive is applied on the surface of the profile to be flocked and The floc is subsequently deposited using electrostatic fields. After leaving the booth or flock zone, the profile is introduced into a hot runner or oven, so that the adhesive polymerizes by temperature
used.

Este método presenta varios inconvenientes, entre los que se encuentran los siguientes:This method has several drawbacks, Among which are the following:

--
Los perfiles requieren habitualmente una superficie flocada muy estrecha en comparación con la anchura del perfil, por lo que el rendimiento de la instalación es bajo.The profiles usually require a very flocked surface narrow compared to the width of the profile, so the Installation performance is low.

--
Se requiere una instalación de gran longitud para el flocado en línea (del orden de 50 ó 60 metros).Be requires a large installation for online flocking (of the order of 50 or 60 meters).

--
Tanto la velocidad de flocado como la velocidad de extrusión del perfil quedan limitadas por el tiempo de reticulado del adhesivo en el canal caliente.So much flocking speed as profile extrusion speed are limited by the time of crosslinking of the adhesive in the hot runner

--
La calidad del flocado obtenido no es totalmente satisfactoria, puesto que los pelos que componen el flocado no quedan perpendiculares a la superficie de flocado, sino formando un ángulo variable con la superficie en función de la curvatura de la misma y su posición espacial.The Flock quality obtained is not entirely satisfactory, since that the hairs that make up the flocking are not perpendicular to the flocking surface, but forming a variable angle with the surface depending on its curvature and its position space.

Son objetivos de la presente invención conseguir un sistema de flocado para perfiles de goma que requiere una instalación que ocupe un mínimo espacio, presente un rendimiento superior, y mediante el cual se obtenga un floc de mayor calidad que mediante los procedimientos actualmente conocido para este tipo de perfiles.The objectives of the present invention are to achieve  a flocking system for rubber profiles that requires a installation that occupies a minimum space, presents a performance superior, and by which a higher quality floc is obtained that by the procedures currently known for this type of profiles.

Para ello, la presente invención prevé la utilización de una cinta flocada que previamente se ha cortado a la anchura necesaria y se pone en contacto con el perfil de goma a una temperatura adecuada, produciendo una unión íntima entre la goma y la cinta flocada.For this, the present invention provides for use of a flocked tape that has previously been cut to the necessary width and contacts the rubber profile at a adequate temperature, producing an intimate union between the rubber and The flocked tape.

Las gomas son materiales termoestables, por lo que, para conseguir la unión mediante calentamiento y contacto prevista por la presente invención, la cinta flocada, que podrá ser del tipo comercialmente disponible, deberá incluir en su base, destinada a hacer contacto con la superficie del perfil, un elemento olefínico compatible con alguno de los polímeros que forman parte de la formulación de la goma.The gums are thermostable materials, so that, to achieve the union by heating and contact provided by the present invention, the flocked tape, which may be of the commercially available type, you must include in your base, intended to make contact with the profile surface, a olefinic element compatible with any of the polymers that They are part of the gum formulation.

Las pruebas y experimentaciones realizadas por los inventores muestran que la presencia del citado elemento olefínico en la base de la cinta hace posible, de manera sorprendente, una unión mediante temperatura con el perfil de goma de forma íntima y duradera, pese al hecho conocido de ser las gomas materiales termoestables, es decir, que no fluyen con el aumento de temperatura.The tests and experiments carried out by the inventors show that the presence of said element olefinic at the base of the tape makes it possible, so surprising, a union by temperature with the rubber profile in an intimate and lasting way, despite the known fact of being the gums thermostable materials, that is, that do not flow with the increase of temperature.

La temperatura de calentamiento de la cinta deberá estar cercana al punto de fusión del componente olefínico seleccionado.The heating temperature of the tape It should be close to the melting point of the olefinic component selected.

Preferentemente, el componente olefínico será de cadena corta. Más preferentemente, éste será etileno.Preferably, the olefinic component will be of  short chain More preferably, this will be ethylene.

Dependiendo de la composición y estructura de la goma, el componente olefínico presente en la base de la cinta se añadirá como aditivo a la misma.Depending on the composition and structure of the  rubber, the olefinic component present at the base of the tape is will add as an additive to it.

La cinta flocada, existente como producto normal en el mercado, y previamente cortada a la anchura deseada, provendrá durante el proceso de flocado de una bobina.The flocked tape, existing as a normal product  in the market, and previously cut to the desired width, will come during the flocking process of a coil.

La presente invención también consiste en el perfil flocado obtenido mediante el presente procedimiento. Este perfil de goma se caracteriza porque presenta íntimamente unida a su superficie una cinta flocada del tipo disponible comercialmente, formado por una base y un floc, en la que no existe adhesivo intermedio entre ambos componentes.The present invention also consists of the flocked profile obtained by the present procedure. This rubber profile is characterized because it presents intimately attached to its surface a flocked tape of the commercially available type, formed by a base and a floc, in which there is no adhesive intermediate between both components.

El presente procedimiento presenta numerosas ventajas sobre el anteriormente conocido, entre las cuales se pueden citar:The present procedure presents numerous advantages over the previously known, among which They can quote:

- Reducción de la inversión en la línea de flocado. El espacio necesario para aplicar la cinta flocada es de aproximadamente 2 metros, mucho menor que con el procedimiento conocido.- Reduction of investment in the line of flocking The space required to apply the flocked tape is approximately 2 meters, much smaller than with the procedure known.

- Calidad de floc constante a lo largo del perfil.- Constant floc quality throughout the profile.

- Incremento de la velocidad de flocado, al no estar limitado por el tiempo de reticulado. Como consecuencia, se puede aumentar la velocidad de extrusión del perfil.- Increase in flocking speed, by not be limited by the cross-linking time. As a consequence, it You can increase the extrusion speed of the profile.

- Aumento del rendimiento, puesto que se elimina la pérdida del floc que escapa del adhesivo.- Performance increase, since it is eliminated  the loss of the floc that escapes the adhesive.

- Reducción de los denominados costes de calidad. En el caso de un flocado defectuoso no es necesario tirar el perfil, sino que se desecha únicamente la cinta.- Reduction of the so-called costs of quality. In the case of a defective flocking it is not necessary to throw the profile, but only the tape is discarded.

Para su mejor compresión, se adjunta a título de ejemplo ilustrativo pero no limitativo unos dibujos de una realización preferente de la presente invención.For better compression, it is attached as  illustrative but not limiting example some drawings of a preferred embodiment of the present invention.

La figura 6 es un corte transversal según el plano VI-VI de la figura 5.Figure 6 is a cross section according to the VI-VI plane of figure 5.

La figura 7 es una vista en alzado posterior del perfil de la figura 5.Figure 7 is a rear elevational view of the profile of figure 5.

La figura 8 es un detalle de la zona flocada de la sección de la figura 8, en la que se muestra en un detalle adicional, la unión entre el perfil de goma y el perfil flocado.Figure 8 is a detail of the flocked area of the section of figure 8, in which it is shown in detail additional, the union between the rubber profile and the profile flocking

La figura 1 muestra el proceso de fabricación de un perfil (1) de EPDM flocado, en el que se utiliza el procedimiento según la presente invención. Como se puede observar en la figura, la fabricación de un perfil de goma comprende, habitualmente, el paso de extrusión del perfil (2), que precede a una fase de vulcanización mediante microondas o vulcanización UHF, indicada en la figura con el numeral (3), y a una fase posterior de vulcanización mediante aportación de calor en un canal de gas, indicada en la figura con el numeral (4). A la salida de esta última fase de vulcanización, el perfil (1) pasa a la zona (5) de flocado.Figure 1 shows the manufacturing process of  a profile (1) of flocked EPDM, in which the procedure according to the present invention. As you can see in the figure, the manufacture of a rubber profile comprises, usually the profile extrusion step (2), which precedes a microwave vulcanization phase or UHF vulcanization, indicated in the figure with numeral (3), and at a later stage of vulcanization by heat input in a gas channel, indicated in the figure with the numeral (4). At the exit of this last vulcanization phase, the profile (1) passes to the zone (5) of flocking

De manera característica para la presente invención, dentro de la zona de flocado (5) tanto el perfil (1) como la cinta flocada (6) pasan a una zona (7) donde se calientan y luego a una zona (8) donde se ponen en contacto, realizándose la unión, y dando lugar al perfil flocado.Characteristically for this invention, within the flock zone (5) both the profile (1) as the flocked tape (6) pass to an area (7) where they are heated and then to an area (8) where they get in touch, performing the union, and giving rise to the flocked profile.

En el ejemplo mostrado, la cinta flocada (6) ha sido previamente cortada a la anchura deseada (que de manera habitual para la aplicación mostrada en el ejemplo, oscila entre 5 y 30 mm), y entra en la zona de flocado (5) proveniente de un desbobinador (9) motorizado que desbobina un carrete de cinta (6) de modo que la velocidad lineal de avance de la cinta (6) sea igual que la velocidad de extrusión del perfil.In the example shown, the flocked tape (6) has previously cut to the desired width (so usual for the application shown in the example, it ranges from 5 and 30 mm), and enters the flock zone (5) from a motorized unwinder (9) unwinding a reel of tape (6) so that the linear speed of advance of the belt (6) is equal than the extrusion speed of the profile.

La cinta flocada (6) (ver figuras 2 y 3) es de tipo disponible comercialmente. Dicha cinta comprende una cara flocada (10) sobre una base (11) destinada a hacer contacto con la superficie del perfil. La base (11) comprende un compuesto olefínico que es compatible químicamente con alguno de los polímeros del EPDM del perfil, por ejemplo, etileno, lo que nos garantiza, si calentamos la superficie (11) de la cinta (6) hasta una temperatura cercana a al punto de fusión del compuesto olefínico y calentamos la superficie del perfil de EPDM adecuadamente, que se unan por simple contacto, como se observa esquemáticamente en las figura 4, en la que el contacto ha sido representado mediante flechas (A), y la temperatura mediante líneas onduladas (B).The flocked tape (6) (see figures 2 and 3) is of commercially available type. Said tape comprises a face flock (10) on a base (11) intended to make contact with the profile surface. The base (11) comprises an olefinic compound which is chemically compatible with any of the EPDM polymers of the profile, for example, ethylene, which guarantees us, if we heat the surface (11) of the tape (6) to a temperature close to the melting point of the olefinic compound and we heat the surface of the EPDM profile properly, to be joined by simple contact, as shown schematically in Figure 4, in which the contact has been represented by arrows (A), and the temperature by wavy lines (B).

La temperatura de calentamiento de la superficie del perfil (1) de EPDM debe ser del orden de la temperatura de fusión del polímero que realizará la unión con el componente olefínico de la base (11) de la cinta, pero en todo caso inferior a la temperatura de degradación del EPDM.Surface heating temperature  of the EPDM profile (1) must be of the order of the temperature of fusion of the polymer that will make the union with the component olefinic base (11) of the tape, but in any case less than the degradation temperature of the EPDM.

Dependiendo de la composición y estructura del material del perfil, la presente invención prevé la adición como aditivo a la composición del EPDM de un compuesto olefínico compatible con el presente en la cinta flocada (6), para favorecer la unión entre perfil y cinta.Depending on the composition and structure of the profile material, the present invention provides for the addition as EPDM composition additive of an olefinic compound compatible with the present in the flocked tape (6), to favor the union between profile and tape.

Las figuras 5 a 8 muestran un perfil de EPDM destinado a servir como junta en una ventana (1) con cristal deslizable obtenido mediante el procedimiento de la figura 1. En el detalle de la figura 8 puede apreciarse cómo el perfil (1) de goma, objeto de la presente invención se caracteriza por presentar un perfil de goma unido a una cinta flocada (6) compuesta por una base (11) que tiene una cara (10) flocada, estando la cinta (6) unida íntimamente al perfil sin presencia de un adhesivo entre ambos componentes.
