Abstract
Description
La présente invention concerne un procédé de gélification d'une composition de solvants carbonés et, plus particulièrement, la fabrication d'un gel pour une composition nettoyante liquide à base de solvants carbonés. L'invention concerne, en outre, un gel de solvants carbonés et son application pour l'enlèvement des gommes à mâcher. The present invention relates to a gelling process for a composition of carbon-based solvents and, more particularly, to the manufacture of a gel for a liquid cleaning composition based on carbon-based solvents. The invention further relates to a carbon solvent gel and its application for the removal of chewing gum.
L'extraction des gommes à mâcher sur les trottoirs, les bois, les pierres, les moquettes, etc, pose un problème quasiment insoluble et, ni les grandes villes, ni les grandes administrations, par exemple, les sociétés de transport, n'ont réussi à résoudre le problème de façon satisfaisante. The extraction of chewing gum on sidewalks, woods, stones, carpets, etc, poses an almost insoluble problem and, neither large cities nor large administrations, for example, transport companies, have successfully resolved the problem.
L'extraction des gommes à mâcher se fait le plus souvent à l'aide de grattoirs, ce qui a pour inconvénient de laisser des résidus de gomme sur les sols, ou de détériorer purement et simplement les supports sur lesquels se trouvent les gommes à mâcher. The extraction of chewing gums is most often done using scrapers, which has the disadvantage of leaving gum residue on the floors, or outright deteriorating the supports on which the chewing gums are located .
On connaît aussi des bombes cryogéniques ou bombes de froid qui permettent de durcir les gommes à mâcher mais un inconvénient majeur est que l'on arrache des fibres du support lors de l'enlèvement des gommes. Also known are cryogenic bombs or cold bombs which make it possible to harden the chewing gums but a major drawback is that fibers are torn from the support when the gums are removed.
On a décrit dans le brevet US-A-5 080 821 une composition pour enlever des graffitis et des gommes à mâcher. Cette composition comprend
de 25 à 70 % d'alcools dénaturés du type éthanol,
de 30 à 75 % d'un mélange de solvants carbonés.US-A-5 080 821 describes a composition for removing graffiti and chewing gum. This composition includes
from 25 to 70% of denatured alcohols of the ethanol type,
30 to 75% of a mixture of carbon-based solvents.
Le mélange de solvants comprend
de 10 à 35 % en volume d'essence C
de 5 à 25 % en volume d'essence E ; et
de 25 à 50 % en volume d'essence F.The solvent mixture includes
from 10 to 35% by volume of gasoline C
from 5 to 25% by volume of gasoline E; and
25 to 50% by volume of gasoline F.
Cependant une telle composition a un inconvénient majeur, à savoir que les solvants carbonés s'évaporent très vite et, par temps chaud, ils n'ont pas le temps d'agir complètement sur les gommes à mâcher. Ce phénomène est encore renforcé lorsque les gommes à mâcher adhèrent sur des revêtements pierreux comme le granit, le marbre ou le goudron des trottoirs ou routes. En effet par temps chaud, il est bien connu que le granit et le marbre accumulent la chaleur et qu'il en est de même pour le goudron qui peut même fondre. However, such a composition has a major drawback, namely that the carbon-containing solvents evaporate very quickly and, in hot weather, they do not have time to act completely on the chewing gums. This phenomenon is further reinforced when the chewing gums adhere to stony surfaces such as granite, marble or tar on sidewalks or roads. Indeed in hot weather, it is well known that granite and marble accumulate heat and that it is the same for tar which can even melt.
De même, si on utilise une composition voisine constituée d'un mélange d'essences pour enlever les graffiti s, lorsqu'on pulvérise la composition sur une surface verticale, la composition a tendance à couler et la quantité de composition au contact des graffitis en est diminuée, ce qui rend le produit beaucoup moins efficace. Similarly, if a neighboring composition consisting of a mixture of essences is used to remove the graffiti, when the composition is sprayed on a vertical surface, the composition tends to flow and the quantity of composition in contact with the graffiti in is reduced, which makes the product much less effective.
De plus, les solvants hydrocarbonés sont utilisés pour de nombreuses applications de nettoyage et on souhaite en général qu'ils ne s'évaporent que le plus lentement possible pour des raisons de sécurité évidentes et pour une action prolongée. In addition, hydrocarbon solvents are used for many cleaning applications and it is generally desired that they only evaporate as slowly as possible for obvious safety reasons and for prolonged action.
L'invention vise donc à pallier ces inconvénients. The invention therefore aims to overcome these drawbacks.
Un but de l'invention est donc de fournir un gel de solvants carbonés. An object of the invention is therefore to provide a gel of carbon-based solvents.
Un autre but de l'invention est de fournir une composition nettoyante pour graffitis qui ne coule pas. Another object of the invention is to provide a cleaning composition for graffiti which does not drip.
Encore un autre but de l'invention est de fournir une composition nettoyante pour les gommes à mâcher, cette composition s'évaporant très lentement et agissant en quelque minutes sur les gommes à mâcher. Yet another object of the invention is to provide a cleaning composition for chewing gums, this composition evaporating very slowly and acting in a few minutes on chewing gums.
Un quatrième but de l'invention est de fournir un procédé de fabrication de solvants carbonés, de préférence hydrocarbonés, sous forme de gels. A fourth aim of the invention is to provide a process for the production of carbon-based solvents, preferably hydrocarbon-based solvents, in the form of gels.

La description suivante en regard des exemples annexés à titre non limitatif permettra de comprendre comment l'invention peut être mise en pratique. The following description with reference to the non-limiting examples appended will make it possible to understand how the invention can be put into practice.
Exemple caiparatif 1
On réalise la composition suivante:
essence C: 30 % en volume ;
essence E: 10 % en volume
éther monométhylique de dipropylèneglycol: 30 % en volume;
essence F: 10 % en volume
essence A: 20 % en volume.Caiparative example 1
The following composition is produced:
gasoline C: 30% by volume;
essence E: 10% by volume
dipropylene glycol monomethyl ether: 30% by volume;
essence F: 10% by volume
essence A: 20% by volume.
Cette composition permet d'enlever les gommes à mâcher, mais du fait qu'elle s'évapore en 2 minutes, son action est incomplète et il reste des résidus sur les surfaces poreuses et sur les pierres ou le goudron. This composition removes chewing gum, but because it evaporates in 2 minutes, its action is incomplete and there are residues on porous surfaces and on stones or tar.
Exemple 1
On mélange 10 % de dioxyde de silicium finement divisé et 90 % d'essence C et on obtient une pâte. Puis, on ajoute à cette pâte un solvant polaire, par exemple de ltéthanol, jusqu'à obtenir un gel.Example 1
10% of finely divided silicon dioxide and 90% of gasoline C are mixed and a paste is obtained. Then, a polar solvent, for example ethanol, is added to this paste until a gel is obtained.
On ajoute ensuite à ce gel la composition nettoyante de l'exemple comparatif à raison de 80 % de composition et 20 % de gel. On obtient une composition sous forme de gel qui, lorsqu'on la fait agir sur des gommes à mâcher qui se trouvent sur des pierres, s'évapore très lentement. Au bout de 10 minutes, les gommes à mâcher se rétractent complètement et se détachent du support sans laisser de traces. De plus, la quantité de produit nécessaire pour enlever les gommes est très faible, car il n'est pas nécessaire de vaporiser plusieurs fois la composition sur les gommes. The cleaning composition of the comparative example is then added to this gel at the rate of 80% of composition and 20% of gel. A composition is obtained in the form of a gel which, when it is acted on chewing gums which are on stones, evaporates very slowly. After 10 minutes, the chewing gums fully retract and detach from the support without leaving any traces. In addition, the amount of product required to remove the gums is very low, since it is not necessary to spray the composition several times on the gums.
Exemple comparatif 2
On réalise la composition suivante:
essence C: 30 % en volume
essence E: 20 % en volume
éther monométhylique de dipropylèneglycol: 30 % en volume;
essence F: 10 % en volume
essence A: 10 % en volume.Comparative example 2
The following composition is produced:
gasoline C: 30% by volume
essence E: 20% by volume
dipropylene glycol monomethyl ether: 30% by volume;
essence F: 10% by volume
essence A: 10% by volume.
Cette composition permet d'enlever les graffitis, mais elle à tendance à couler vers le bas lorsqu'elle est déposée sur une surface verticale ou inclinée. Ainsi, on est obligé de vaporiser plusieurs fois du produit sur la surface, ce qui entraîne un gaspillage. This composition removes graffiti, but it tends to flow down when it is placed on a vertical or inclined surface. Thus, we are forced to spray the product several times on the surface, which results in waste.
Exemple 2
On réalise un gel en prenant la composition de l'exemple précédent. Le gel obtenu est ensuite projeté sur une surface comportant des graffitis. Cette composition ne coule pas et il n'est pas nécessaire de la déposer à plusieurs reprises sur la surface à nettoyer. On utilise donc beaucoup moins de produit.Example 2
A gel is produced by taking the composition of the previous example. The gel obtained is then sprayed onto a surface containing graffiti. This composition does not drip and it is not necessary to deposit it repeatedly on the surface to be cleaned. We therefore use much less product.
Bien que l'on ait décrit ce que l'on considère actuellement être les modes de réalisation préférés de la présente invention, il est évident que l'Homme de l'Art pourra y apporter différents changements et modifications sans sortir du cadre de la présente invention tel que défini ci-après. Although we have described what are currently considered to be the preferred embodiments of the present invention, it is obvious that a person skilled in the art can make various changes and modifications without departing from the scope of the present. invention as defined below.
