Description
Líquido sellante anti-pinchazos para ruedas de bicicleta.Anti-puncture sealant liquid for bicycle wheels.
La presente invención se refiere a un líquido sellante, que ha sido especialmente concebido para ruedas de bicicleta, especialmente para ruedas tipo "tubeless", es decir para ruedas con cubierta sin cámara, donde el líquido de la invención actúa como elemento anti-pinchazos y para eliminar las clásicas fugas de aire en este tipo de ruedas, que obligan a reponer el aire prácticamente a diario, a la vez que permite convertir una cubierta convencional, prevista para su utilización con cámara, en una cubierta tubeless mediante un perfecto sellado entre cubierta y llanta de la rueda.The present invention relates to a liquid sealant, which has been specially designed for wheels of bicycle, especially for tubeless wheels, that is for wheels with a cameraless cover, where the liquid from the invention acts as an anti-puncture element and for eliminate the classic air leaks in this type of wheels, which force to replenish the air almost daily, while allows converting a conventional cover, intended for use with camera, in a tubeless cover by means of a Perfect sealing between tire and wheel rim.
Como es sabido en el ámbito de la bicicleta existen dos tipos de ruedas, las ruedas clásicas con cámara y las ruedas carentes de ella, comúnmente denominadas "tubeless", en las que un especial acabado de la llanta y un perfecto acoplamiento de la cubierta a la misma, determinan un ajuste adecuado entre ambas piezas para evitar la pérdida de aire.As is known in the field of cycling There are two types of wheels, the classic wheels with camera and the wheels lacking it, commonly called "tubeless", in which a special rim finish and a perfect coupling from the cover to it, determine an appropriate fit between Both pieces to prevent air loss.
Las cubiertas "tubeless", con independencia de que se ven sometidas a pinchazos al igual que las cubiertas clásicas, aunque con menor intensidad, sufren pequeñas pérdidas de aire que obligan a un periódico inflado de las mismas, prácticamente diario."Tubeless" covers, regardless that they are subjected to punctures just like the covers classical, although with less intensity, suffer small losses of air that forces an inflated newspaper of them, practically daily
Tratando de resolver esta problemática, tanto la de los pinchazos como la de pérdida de aire en las ruedas tubeless, son conocidos productos sellantes, a base de látex, que introducidos en el interior de la rueda son capaces de sellar cualquier poro o pinchazo de la misma, entre los que cabe destacar los comercializados con las marcas "Eclipse" de origen suizo y "Velox" y "Notubex" de origen americano.Trying to solve this problem, both the of punctures such as air loss in tubeless wheels, latex based sealant products are known, which introduced inside the wheel are able to seal any pore or puncture of it, among which it is worth highlighting those marketed under the "Eclipse" brands of Swiss origin and "Velox" and "Notubex" of American origin.
Estos productos se comercializan en forma de disolución, con una importante cantidad de agua u otro disolvente, lo que repercute negativamente en la eficacia del producto, y además requieren del desmontaje de la cubierta con respecto a la correspondiente llanta para efectuar su aplicación, lo que hace que su utilización resulte compleja e incómoda.These products are marketed in the form of solution, with a significant amount of water or other solvent, which negatively affects the effectiveness of the product, and they also require the disassembly of the cover with respect to the corresponding tire to make its application, which makes its use is complex and uncomfortable.
El líquido sellante que la invención propone, aun basándose también en la utilización de látex como materia prima fundamental, presenta una serie de aditivos que mejoran sustancialmente sus prestaciones, especialmente en lo que se refiere a la unión entre la llanta y la cubierta, y que permite a su vez su aplicación a la rueda mediante inyección, con la colaboración de una aguja con jeringuilla, sin necesidad de desmontar la cubierta, consistiendo la primera acción del líquido en el cierre instantáneo del orifico dejado por la aguja de aplicación del producto.The sealing liquid that the invention proposes, even also based on the use of latex as raw material fundamental, it presents a series of additives that improve substantially its benefits, especially as far as refers to the junction between the tire and the tire, and that allows turn its application to the wheel by injection, with the Collaboration of a needle with syringe, without the need for disassemble the cover, consisting of the first action of the liquid at the instant closure of the hole left by the needle of product application.
Para ello y de forma más concreta el líquido sellante que la invención propone está compuesto a partir de látex natural líquido, en una proporción comprendida entre el 72 y el 80%, alkyl concentrado puro en una proporción comprendida entre el 14 y el 18% y látex vinílico de alta viscosidad en una proporción comprendida entre el 6 y el 8%.For this and more specifically the liquid sealant proposed by the invention is made from latex natural liquid, in a proportion between 72 and 80%, pure concentrated alkyl in a proportion between 14 and 18% and high viscosity vinyl latex in a proportion between 6 and 8%.
Sobre el 100% del producto líquido obtenido con los tres componentes anteriormente citados, se incorpora posteriormente y se disuelve en el mismo pimentón molido, en una proporción comprendida entre el 4 y el 8%.Over 100% of the liquid product obtained with The three components mentioned above are incorporated later and dissolves in the same ground paprika, in a proportion between 4 and 8%.
El alkyl confiere al producto su propio efecto adhesivo, de forma que la llanta y cubierta quedan mejor unidas evitando pérdida de presión en situaciones extremas, sin que dicho adhesivo haga posteriormente que la rueda sea difícil de desmontar, mientras que el pimentón incrementa la capacidad de sellado en el caso de pinchazos de mayores dimensiones, aglomerándose en el seno del resto de los componentes del producto.The alkyl gives the product its own effect adhesive, so that the tire and cover are better joined avoiding loss of pressure in extreme situations, without saying adhesive subsequently make the wheel difficult to disassemble, while paprika increases the sealing capacity in the case of larger punctures, agglomerating in the breast of the rest of the product components.
Para la obtención de un litro de producto se utilizaron 760 mm de látex natural líquido, 160 mm de alkyl concentrado puro, y 80 mm de látex sintético extra brillante, vinílico de alta viscosidad.To obtain a liter of product, they used 760 mm of natural liquid latex, 160 mm of alkyl pure concentrate, and 80 mm of extra bright synthetic latex, High viscosity vinyl.
Los tres componentes fueron removidos hasta conseguir una adecuada homogeneidad en la mezcla, y a este litro de producto se añadieron posteriormente 60 cm3 de pimentón molido, removiéndose de nuevo hasta conseguir recuperar la homogeneidad de la mezcla.The three components were removed until achieve adequate homogeneity in the mixture, and at this liter of product was subsequently added 60 cm3 of ground paprika, stirring again until the homogeneity of mix.
Del producto obtenido se introdujeron, mediante inyección, 12,5 mm disueltos en 37,5 mm de agua, para rebajar la densidad del citado producto y facilitar que el mismo se reparta correctamente por el interior de la rueda, obteniéndose como resultado inmediato, en las ruedas tipo "tubeless" una total eliminación de las clásicas y pequeñas pérdidas constantes de aire, de manera que las cubiertas mantenían su presión de inflado, constante, múltiples días después de la aplicación del producto.Of the product obtained were introduced, by injection, 12.5 mm dissolved in 37.5 mm of water, to reduce the density of said product and facilitate that it is distributed correctly inside the wheel, obtaining as immediate result, in the "tubeless" type wheels a total elimination of classic and small constant air losses, so that the covers maintained their inflation pressure, constant, multiple days after product application.
Se obtuvieron resultados similares en ruedas provistas de cubiertas convencionales con cámara, tras la eliminación de dicha cámara para convertirlas en ruedas tubeless.Similar results were obtained in wheels provided with conventional camera covers, after the elimination of said camera to turn them into wheels tubeless
Durante el periodo de ensayo no se produjeron aparentemente pinchazos en las ruedas, y dado que dichos pinchazos realmente existieron, se evidencia que los mismos fueron automáticamente cerrados con el líquido sellante.During the trial period there were no apparently punctures on the wheels, and given that said punctures they really existed, it is evident that they were automatically closed with sealing liquid.
