OBJETO DE LA INVENCIONOBJECT OF THE INVENTION

1010

La presente invention se refiere a un producto antipinchazos para neumaticos, utilizable para la prevention y reparacion inmediata de pinchazos en neumaticos de vehiculos teles como coches, motocicletas, camiones y similares.The present invention relates to an anti-puncture product for tires, usable for the prevention and immediate repair of punctures in tires of telescopes such as cars, motorcycles, trucks and the like.

ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION

En la actualidad se conocen unos productos antipinchazos que comprenden una suspension de particulas no solubles en un medio liquido, destinada a introducirse en el interior del 15 neumatico, de forma que el giro de la rueda reparte el producto por el interior del neumatico, recubriendo el mismo. En caso de pinchazo este recubrimiento actua como camara interior que tapona la falla del neumatico provocada por el pinchazo.At present, anti-puncture products are known which comprise a suspension of particles that are not soluble in a liquid medium, intended to be introduced inside the tire, so that the rotation of the wheel distributes the product inside the tire, covering the same. In case of a puncture this coating acts as an inner chamber that blocks the tire failure caused by the puncture.

Algunas veces dicho producto comprende componentes que pueden resultar corrosivos o que 20 atacan el material del neumatico a largo plazo, con el consiguiente peligro de reventon.Sometimes this product comprises components that can be corrosive or that attack the tire material in the long term, with the consequent danger of bursting.

Dichos productos presentan diversos problemas, entre los que cabe destacar:These products present various problems, among which are:

-defectos en el sellado debido a la baja viscosidad del medio liquido, con lo que la reparacion 25 muchas veces es inefectiva.-sealing defects due to the low viscosity of the liquid medium, so repair 25 is often ineffective.

-elevado peso, que puede cambiar el comportamiento del vehiculo o producir vibraciones. -cambios de comportamiento con las variaciones de temperatura, problema frecuente que ademas es inevitable teniendo en cuenta que el regimen de funcionamiento de un neumatico implica cambios frecuentes e incluso bruscos de temperatura.- High weight, which can change the behavior of the vehicle or produce vibrations. Changes in behavior with temperature variations, a frequent problem that is also inevitable considering that the operating regime of a tire implies frequent and even sudden changes in temperature.

DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION

El producto antpinchazos de la invention tiene una constitution que soluciona los problemas tecnicos expuestos.The anti-puncture product of the invention has a constitution that solves the exposed technical problems.

El producto antipinchazos para neumaticos es del tipo que comprenden una suspension de partlculas no solubles en un medio liquido, destinada a introducirse en el interior del neumatico, de forma que se reparte perimetralmente por el interior del mismo formando un 5 recubrimiento interior que, en caso de pinchazo es introducido por la abertura del pinchazo por la presion interior de inflado, realizando un sellado gracias a las partlculas incluidas en el mismo en cooperation con las propiedades adherentes que adicionalmente tenga el medio liquido.The anti-puncture product for tires is of the type that comprises a suspension of particles that are not soluble in a liquid medium, intended to be introduced inside the tire, so that it is distributed perimetrically through the interior of the tire, forming an inner coating that, in case of puncture is introduced by the opening of the puncture by the internal inflation pressure, making a seal thanks to the particles included therein in cooperation with the adherent properties that the liquid medium additionally has.

10 Con esta configuracion basica, y de acuerdo con la invencion, el medio liquido comprende una mezcla homogenea de:10 With this basic configuration, and according to the invention, the liquid medium comprises a homogeneous mixture of:

55%-75% de glicerina, y 25%-45% de agua55% -75% glycerin, and 25% -45% water

15 Con esta configuracion, de forma general se consigue aumentar la densidad del medio liquido aumentando la capacidad de taponamiento del producto, siendo por tanto capaz de taponar pinchazos de mayor tamano o afectacion del neumatico, al ofrecer un rozamiento mayor con los bordes de los mismos.15 With this configuration, in general it is possible to increase the density of the liquid medium by increasing the capacity of clogging of the product, being therefore able to plug punctures of greater size or involvement of the tire, by offering a greater friction with the edges of the same .

20 Debido a que la elevada densidad de la glicerina, no seria esperable un buen resultado en cuanto a la dispersion de las partlculas no solubles, lo que constituye un prejuicio o razon por la cual no se utiliza la misma en productos antipinchazos. Por esta causa la invencion ha previsto que preferentemente algunas o todas las partlculas no solubles se encuentran preimpregnadas en glicerina antes de ser anadidas al medio liquido en la preparation del20 Because the high density of glycerin, a good result would not be expected in terms of dispersion of the non-soluble particles, which constitutes a prejudice or reason why it is not used in puncture products. For this reason the invention has provided that preferably some or all of the non-soluble particles are preimpregnated in glycerin before being added to the liquid medium in the preparation of the

25 producto.25 product

Otras ventajas de la utilization de este medio liquido en el producto comprenden:Other advantages of using this liquid medium in the product include:

-La glicerina es una sustancia no contaminante y biodegradable a medio plazo, por lo que el-Glycerin is a non-polluting and biodegradable substance in the medium term, so the

30 producto tiene una nula afeccion medioambiental.30 product has no environmental impact.

-La glicerina aporta a la mezcla homogenea un punto de congelation muy bajo, evitando la cristalizacion a bajas temperaturas. De este modo en caso de pinchazo se mantienen las propiedades de sellado aunque se deje el vehiculo a la intemperie y se produzca el-Glycerin gives the homogeneous mixture a very low freezing point, avoiding crystallization at low temperatures. In this way, in the event of a puncture, the sealing properties are maintained even if the vehicle is left outdoors and the

enfriamiento del neumatico, situation donde otros productos similares pierden efectividad y donde se produce el desinflado del neumatico.tire cooling, situation where other similar products lose effectiveness and where tire deflation occurs.

-Igualmente la glicerina aporta a la mezcla homogenea una alta temperatura de ebullition, por lo que mantiene las propiedades del producto igualmente a altas temperaturas.- Likewise, glycerin gives the homogeneous mixture a high boiling temperature, so it keeps the properties of the product equally at high temperatures.

Ademas, como efectos inesperados debido a la alta hidrofilia de la glicerina, se ha encontrado un aumento significativo de la estabilidad de la mezcla, produciendo un descenso de la volatilidad del agua de la misma que perjudicaria las proporciones de la mezcla, evitando que la densidad aumente en exceso y permitiendo un optimo reparto por el interior del neumatico. Ademas, el producto no se pega al girar el neumatico, impidiendo que el recubrimiento pueda ser perforado por un objeto punzante que cause un pinchazo. Ademas, en la mezcla no ocurren oxidaciones que igualmente puedan perjudicar las propiedades del producto con el tiempo y los cambios de temperatura por el uso.In addition, as unexpected effects due to the high hydrophilicity of glycerin, a significant increase in the stability of the mixture has been found, resulting in a decrease in water volatility that would impair the proportions of the mixture, preventing the density increase excessively and allowing an optimal distribution inside the tire. In addition, the product does not stick when the tire is rotated, preventing the coating from being punctured by a sharp object that causes a puncture. In addition, oxidations do not occur in the mixture that can also damage the properties of the product over time and changes in temperature due to use.

DESCRIPCION DE UNA REALIZACION PRACTICA DE LA INVENCIONDESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

El producto antipinchazos para neumaticos (1) de la invention tiene una configuration basica del tipo que comprenden una suspension de particulas (3a, 3b) no solubles en un medio liquido (4), destinada a introducirse en el interior del neumatico (1) y taponar el pinchazo (5) (ver fig 1 y 2), donde de acuerdo con la invention, el medio liquido (4) comprende una mezcla homogenea de:The tire puncture product (1) of the invention has a basic configuration of the type comprising a suspension of particles (3a, 3b) not soluble in a liquid medium (4), intended to be introduced inside the tire (1) and plug the puncture (5) (see figs. 1 and 2), where according to the invention, the liquid medium (4) comprises a homogeneous mixture of:

55%-75% de glicerina, y55% -75% glycerin, and

25%-45% de agua.25% -45% water.

Dentro de este intervalo, se ha encontrado un mejor funcionamiento si la mezcla homogenea del medio liquido (4) comprende:Within this range, better performance has been found if the homogeneous mixture of the liquid medium (4) comprises:

66% de glicerina, y 34% de agua.66% glycerin, and 34% water.

Algunas o todas las particulas (3a, 3b) no solubles se encuentran preimpregnadas en glicerina antes de ser anadidas al medio liquido (4), lo que favorece su dispersion por el medio liquidoSome or all of the particles (3a, 3b) not soluble are preimpregnated in glycerin before being added to the liquid medium (4), which favors their dispersion through the liquid medium

(4).(4).

En una variante muy preferida de la invention, el agua contenida en la mezcla homogenea del medio liquido (4) comprende agua destilada, de forma que se evita la existencia de contaminantes que puedan afectar al funcionamiento y/o estabilidad del producto. Ademas, se ha previsto que la mezcla homogenea del medio liquido (4) adicionalmente pueda comprender productos biocidas que evitaran la proliferation de hongos u otros microorganismos en el medio humedo y que puedan afectar a las propiedades del producto, o perjudicar la integridad del neumatico (1). Dichos biocidas por ejemplo pueden comprender mezclas comerciales de 1, 2 - bencisotiazol - 3 (2H) - ona, 2-metil-2H-isotiazol-3-ona y N-(3-Aminopropil)-N- dodecilpropano-1,3-diamina, como el parmetol MBX®, y su proportion maxima sera la admitida por las normativas de seguridad de utilizacion, como maximo un 1% en volumen y 99% de la mezcla de glicerina y agua en las proporciones anteriormente citadas.In a very preferred variant of the invention, the water contained in the homogeneous mixture of the liquid medium (4) comprises distilled water, so that the existence of contaminants that can affect the operation and / or stability of the product is avoided. In addition, it is envisaged that the homogeneous mixture of the liquid medium (4) may additionally comprise biocidal products that will prevent the proliferation of fungi or other microorganisms in the moist environment and that may affect the properties of the product, or impair the integrity of the tire ( one). Such biocides, for example, may comprise commercial mixtures of 1,2-benzothiazol-3 (2H) -one, 2-methyl-2H-isothiazol-3-one and N- (3-Aminopropyl) -N-dodecylpropane-1,3- diamine, such as MBX® parmetol, and its maximum proportion will be that admitted by the safety regulations for use, at most 1% by volume and 99% of the glycerin and water mixture in the aforementioned proportions.

Como particulas no solubles se pueden utilizar unas particulas resistentes a la traccion (3a) que formaran interiormente un entrelazado (2) sobre las comisuras (10) del pinchazo (5), como se ve en la figura 3, gracias a la viscosidad del medio liquido (4) que retendra la salida de dicho entrelazado (2) por el pinchazo (5), y con la cooperation opcional de unas particulas de relleno (3b), que rellenan los huecos de dicho entrelazado (2). Opcionalmente tambien se podrian utilizar unicamente particulas de relleno (3b), que funcionarian bien en pinchazos pequenos, pero para pinchazos grandes se prefiere su utilizacion conjuntamente con particulas resistentes a la traccion (3a).As non-soluble particles, traction resistant particles (3a) can be used that will internally form an interlocking (2) on the corners (10) of the puncture (5), as seen in Figure 3, thanks to the viscosity of the medium liquid (4) that retains the exit of said interlaced (2) by the puncture (5), and with the optional cooperation of filling particles (3b), which fill the gaps of said interlaced (2). Optionally you could also use only filler particles (3b), which would work well in small punctures, but for large punctures it is preferred to use them together with tensile particles (3a).

Las particulas resistentes a la traccion (3a) comprenden muy preferentemente fibras deThe tensile resistant particles (3a) most preferably comprise fibers of

carbono tubulares huecas, que mejoran la retention interior de humedad del medio liquido (4)hollow tubular carbon, which improves the internal moisture retention of the liquid medium (4)

Dichas fibras de carbono tienen longitudes idealmente comprendidas entre 0,1 y 0,5 milimetros. Por su parte, las particulas de relleno (3b) comprenden preferentemente particulas de dioxido de titanio, debido a la gran dureza y economia de las mismas, pudiendo alcanzar granulometrias muy finas con gran poder de penetracion y sellado del pinchazo. La granulometrla de las mismas sera variada, e idealmente comprendida entre 0,1 y 1 milimetros, de forma que algunas de las mismas penetren y sellen el pinchazo, mientras que otras son las que quedaran retenidas entre los huecos del entrelazado (2) formando un tapon. Ademas, la utilization de particulas de dioxido de titanio sirve de testigo para la localization del pinchazo, ya que son de color bianco y las de menor tamano que penetren por el pinchazo (5) acabaran rebosando por el exterior del neumatico (1), marcando el lugar por donde entro el clavo (7) (ver fig 1) que genera el pinchazo (5).Said carbon fibers have ideally lengths between 0.1 and 0.5 millimeters. On the other hand, the filler particles (3b) preferably comprise titanium dioxide particles, due to the great hardness and economy thereof, being able to reach very fine particle sizes with great penetration and sealing power of the puncture. The granulometrla of the same will be varied, and ideally between 0.1 and 1 millimeters, so that some of them penetrate and seal the puncture, while others are those that will be retained between the gaps of the interlacing (2) forming a plug. In addition, the use of titanium dioxide particles serves as a witness for the localization of the puncture, since they are of white color and those of smaller size that penetrate through the puncture (5) will end up overflowing with the outside of the tire (1), marking the place where the nail (7) entered (see fig 1) that generates the puncture (5).

Adicionalmente, las particulas de relleno (3b) pueden comprender particulas de arcillas (sepiolita y bentonita) y/o de caucho, que generan grandes rozamientos entre si, mejorando el sellado. Su granulometrla preferida seria similar a la de las particulas de dioxido de titanio.Additionally, the filler particles (3b) may comprise clays (sepiolite and bentonite) and / or rubber particles, which generate large friction with each other, improving sealing. Its preferred particle size would be similar to that of titanium dioxide particles.

Descrita suficientemente la naturaleza de la invention, asi como la manera de realizarse en la practica, debe hacerse constar que las disposiciones anteriormente indicadas y representadas en los dibujos adjuntos son susceptibles de modificaciones de detalle en cuanto no alteren el principio fundamental.Described sufficiently the nature of the invention, as well as the way of carrying it out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter the fundamental principle.
