Abstract

Aqueous composition for cleaning surfaces comprises 10-40 wt.% sodium, potassium or ammonium formate and has a pH of 7-9. An Independent claim is included for use of the product for the elimination of the stains on the frontages of buildings, particularly caused by air pollution.

Description

La présente invention concerne un produit de nettoyage de surfaces pour en éliminer les salissures, et notamment de façades d'immeubles ou toutes autres surfaces couvertes de salissures liées à la pollution atmosphérique.The present invention relates to a cleaning product for surfaces to remove dirt, including building facades or any other surfaces covered with soiling from air pollution.

L'atmosphère des villes devient de plus en plus chargée et concentrée en produits de combustion. Ceux-ci, plus ou moins gras et mélangés aux poussières, déposent avec le temps un dépôt dur, noir ou de couleur tendant vers le noir, très adhérent et inesthétique, sur des surfaces telles que les façades d'immeubles.The urban atmosphere is becoming more and more charged and concentrated in combustion products. These, more or less greasy and mixed with dust, deposit over time a hard deposit, black or color tending towards black, very adherent and unsightly, on surfaces such as facades buildings.

L'anhydride sulfureux SO2, très présent dans ces dépôts réagit avec ces surfaces, généralement calciques, pour donner un sulfate de calcium difficile à éliminer, conduisant dans certains cas à la dégradation du matériau lui même par formation de sulfate de calcium dihydraté.The sulfur dioxide SO 2 , very present in these deposits reacts with these surfaces, generally calcium, to give a calcium sulfate difficult to remove, leading in some cases to the degradation of the material itself by the formation of calcium sulfate dihydrate.

On connaít déjà différents procédés de nettoyage de surfaces couvertes de salissures, en particulier des procédés de nettoyage par abrasion tels que le sablage et le gommage. Ces procédés présentent cependant l'inconvénient d'être coûteux et de ne pas respecter les surfaces traitées.We already know different methods of cleaning surfaces covered with dirt, in particular methods of abrasion cleaning such as sandblasting and scrubbing. These processes have the disadvantage of being costly and not to respect the treated surfaces.

On connaít aussi les procédés de nettoyage par action chimique, notamment les procédés utilisant des lessives fortement basiques, dangereuses pour l'utilisateur et risquant de fragiliser les surfaces calciques. L'utilisation de ces lessives basiques peut donner lieu, avec le temps, à la formation d'efflorescences peu esthétiques.We also know the cleaning methods by action chemical, especially processes using detergents strongly basic, dangerous for the user and likely to weaken calcium surfaces. Use of these detergents can lead to training over time unattractive efflorescence.

En outre, les procédés de nettoyage par abrasion ou par action chimique nécessitent de protéger les ouvertures pouvant exister, notamment sur les façades d'immeubles, telles que les portes, les fenêtres, ou les vérandas. En effet, ces ouvertures risquent, lors du nettoyage, d'être atteintes par les projections d'abrasifs ou de lessives, pouvant ainsi endommager les boiseries, les peintures, les vitres ou les structures en aluminium de ces ouvertures.In addition, methods of cleaning by abrasion or by chemical action requires protecting openings that may exist, especially on the facades of buildings, such as doors, windows, or verandas. Indeed, these openings may, during cleaning, be touched by splashes abrasives or detergents, which could damage the woodwork, paints, windows or aluminum structures of these openings.

La présente invention a donc pour objet un produit de nettoyage simple et efficace, qui remédie aux inconvénients de l'art antérieur et permet notamment d'éliminer les dépôts polluants très adhérents et inesthétiques.The present invention therefore relates to a product of simple and effective cleaning, which overcomes the disadvantages of the prior art and in particular makes it possible to remove deposits highly adherent and unsightly pollutants.

La présente invention a pour objet un produit de nettoyage de surfaces pour éliminer les salissures consistant en une composition aqueuse contenant au moins un formiate de sodium, de potassium, ou d'ammonium, avantageusement du formiate d'ammonium, ledit formiate étant présent à raison de 10 à 40 % en poids par rapport au poids total du produit, et ladite composition possédant un pH de 7 à 9 environ et de préférence d'environ 8.The present invention relates to a cleaning product surfaces to remove dirt consisting of aqueous composition containing at least one sodium formate, potassium, or ammonium, advantageously formate ammonium, said formate being present in an amount of 10 to 40% by weight relative to the total weight of the product, and said composition having a pH of approximately 7 to 9 and preferably about 8.

En faisant réagir le formiate de sodium, de potassium, ou d'ammonium sur le sulfate de calcium peu soluble, présent sur les surfaces polluées, on obtient du carbonate de calcium peu adhérant et du sulfate de sodium, de potassium, ou d'ammonium soluble, ces deux produits de réaction pouvant être facilement éliminés à l'eau.By reacting sodium, potassium, or of ammonium on poorly soluble calcium sulfate, present on polluted surfaces, we get little calcium carbonate adhering and sodium, potassium, or ammonium sulfate soluble, these two reaction products can be easily eliminated with water.

Le pH proche de la neutralité permet d'éviter toute réaction du produit de nettoyage avec les matériaux du support traité, et plus particulièrement lorsque celui-ci est en pierre calcaire, en brique, ou en ciment.The near-neutral pH prevents any reaction cleaning product with the materials of the treated support, and more particularly when it is made of limestone, in brick, or cement.

En outre, le produit de nettoyage selon l'invention est sans effet sur les vitres, les boiseries, les peintures et les structures en aluminium des ouvertures que l'on rencontre habituellement sur les façades d'immeubles. Par conséquent, il n'est pas nécessaire de protéger les ouvertures présentes sur les façades à nettoyer lors du nettoyage de ces dernières à l'aide du produit selon l'invention.In addition, the cleaning product according to the invention is without effect on windows, woodwork, paints and structures aluminum openings that are commonly encountered on the facades of buildings. Therefore, it is not necessary to protect the openings on the facades to be cleaned when cleaning them with the product according to the invention.

Le produit de nettoyage selon l'invention peut également comprendre un ou plusieurs agents tensioactifs, de préférence non moussant(s) ou faiblement moussant(s).The cleaning product according to the invention can also include one or more surfactants, preferably non-foaming or weakly foaming.

Le choix des tensioactifs peut s'avérer important, car ces constituants agissent en synergie avec le formiate. Les tensioactifs aident également à la dissolution des corps gras, et par conséquent à l'élimination de l'ensemble des produits de combustion polluants plus ou moins gras.The choice of surfactants can be important, because these constituents act in synergy with formate. The surfactants also help dissolve fatty substances, and consequently to the elimination of all the products of more or less fatty pollutants.

Les agents tensioactifs utilisables selon l'invention représentent généralement de 2 à 10% en poids du poids total du produit de nettoyage selon l'invention.Surfactants usable according to the invention generally represent from 2 to 10% by weight of the total weight of the cleaning product according to the invention.

De manière avantageuse, le ou les agents tensioactifs sont amphotères.Advantageously, the surfactant (s) are amphoteric.

A titre d'exemple d'agent tensioactif amphotère utilisable selon l'invention, on peut citer le sel de sodium d'alkylamine commercialisé sous la dénomination AMPHOTENSID EH par la société ZSCHIMMER & SCHWARZ. Cet agent tensioactif est non seulement un excellent solubilisant des corps gras, mais il est également non moussant.As an example of an amphoteric surfactant which can be used according to the invention, mention may be made of the sodium salt of alkylamine marketed under the name AMPHOTENSID EH by the ZSCHIMMER & SCHWARZ. This surfactant is not only an excellent solubilizer for fatty substances, but it is also non-foaming.

De préférence, le ou les agents tensioactifs sont associés à un sel d'ammonium quaternaire.Preferably, the surfactant (s) are combined to a quaternary ammonium salt.

A titre d'exemple de dérivé d'ammonium quaternaire utilisable selon l'invention, on citera le chlorure d'acétyle diméthylammonium commercialisé par la société VALUY sous la dénomination VITALUB QA5D Na, qui est un bon détergent et est en outre fongicide, bactéricide et algicide.As an example of a quaternary ammonium derivative usable according to the invention, mention will be made of acetyl chloride dimethylammonium marketed by VALUY under the name VITALUB QA5D Na, which is a good detergent and is in addition fungicide, bactericide and algicide.

Étant donné que le produit selon l'invention est une composition aqueuse de nettoyage destinée à être appliquée, dans bien des cas, sur des surfaces verticales inclinées, il comprend généralement au moins un additif choisi parmi les agents épaississants, les agents viscosifiants, les agents gélifiants et leurs mélanges. En effet, les additifs favorisent l'adhérence du produit de nettoyage selon l'invention sur les surfaces à nettoyer, en particulier les surfaces verticales ou inclinées, de sorte que le produit de nettoyage selon l'invention reste en contact d'une manière permanente, généralement plusieurs heures avec la surface à nettoyer, sans pour autant que le produit ne coule ou ne se dessèche prématurément par évaporation.Since the product according to the invention is a aqueous cleaning composition intended to be applied, in many cases, on inclined vertical surfaces, it generally includes at least one additive chosen from thickening agents, viscosifiers, agents gelling agents and their mixtures. Indeed, additives promote the adhesion of the cleaning product according to the invention to the surfaces to be cleaned, especially vertical surfaces or inclined, so that the cleaning product according to the invention stays in touch permanently, usually several hours with the surface to be cleaned, without that the product does not leak or dry out prematurely by evaporation.

En outre, ces additifs permettent également de limiter l'action du produit à la surface du support.In addition, these additives also make it possible to limit the action of the product on the surface of the support.

A titre d'exemple d'agent épaississant utilisable selon l'invention, on peut citer l'éthyl cellulose ou la carboxyméthyl cellulose, notamment le produit commercialisé par la société HERCULES sous la dénomination BLANOSE 12 M 31 F.As an example of a thickening agent which can be used according to the invention, mention may be made of ethyl cellulose or carboxymethyl cellulose, in particular the product marketed by the company HERCULES under the name BLANOSE 12 M 31 F.

Les agents viscosifiants utilisables selon l'invention peuvent avantageusement être choisis parmi les agents viscosifiants hydrophiles rétenteurs d'eau, qui présentent l'avantage de conserver pendant plusieurs heures le produit humide, ralentissant ainsi son évaporation.The viscosifying agents which can be used according to the invention can advantageously be chosen from agents hydrophilic water-retaining viscosifiers, which have the advantage of keeping the product for several hours humid, slowing down its evaporation.

A titre d'agent viscosifiant hydrophile utilisable selon l'invention, on peut citer la gomme xanthane commercialisée par la société MONSANTO sous la dénomination KELZAN S.As hydrophilic viscosifying agent usable according to the invention, mention may be made of xanthan gum sold by MONSANTO under the name KELZAN S.

Les agents gélifiants utilisables selon l'invention sont de manière avantageuse thixotropes, pour que le produit de nettoyage selon l'invention reste bien en place sur la surface sans couler.The gelling agents which can be used according to the invention are of advantageously thixotropic, so that the product of cleaning according to the invention remains firmly in place on the surface without sinking.

A titre d'agents gélifiants utilisables selon l'invention, on peut citer des colloïdes minéraux naturels ou synthétiques, notamment la bentonite, les colloïdes à base d'aluminosilicate commercialisées par la société LAPORTE sous la dénomination Laponite RDS, ou l'AEROSIL de la société DEGUSSA.As gelling agents which can be used according to the invention, may include natural or synthetic mineral colloids, especially bentonite, colloids based on aluminosilicate marketed by LAPORTE under the name Laponite RDS, or AEROSIL from DEGUSSA.

Le ou les additifs utilisables selon l'invention sont généralement présents à raison de 2 à 10% en poids du poids total de la composition. Les proportions de ces additifs pouvant varier en fonction des moyens d'application utilisés (projection, rouleau, spatule, brosse) et de la nature des matériaux constitutifs des surfaces à nettoyer.The additive (s) which can be used according to the invention are generally present at 2 to 10% by weight of the weight total of the composition. The proportions of these additives can vary depending on the means of application used (projection, roller, spatula, brush) and the nature of the materials constituting the surfaces to be cleaned.

Le produit de nettoyage selon l'invention peut également comprendre un agent antimousse, notamment siliconé, présent à raison de 0,1 à 1% en poids, et de préférence à raison de 0,6% en poids par rapport au poids total du produit selon l'invention.The cleaning product according to the invention can also include an anti-foaming agent, in particular a silicone agent, present 0.1 to 1% by weight, and preferably 0.6% by weight relative to the total weight of the product according to the invention.

A titre d'exemple d'agent antimousse siliconé on peut citer le RHODORSIL 426R commercialisé par la société RHONE POULENC.As an example of a silicone antifoaming agent, mention may be made of RHODORSIL 426R marketed by RHONE Poulenc.

Le produit de nettoyage selon l'invention peut également comprendre des additifs autres que ceux cités précédemment, choisis notamment parmi la triéthanolamine, la monoéthanolamine, la glycérine, les alcools polyvinyliques, les argiles colloïdales, et les bentonites.The cleaning product according to the invention can also include additives other than those mentioned above, chosen in particular from triethanolamine, the monoethanolamine, glycerin, polyvinyl alcohols, colloidal clays, and bentonites.
