Description

COMPOSIONS AQUEUSES POUR LE TRAITEMENT ANTISAUSSURE DES
MATERIAUX DECONSTRUCTION
La présente invention concerne le traitement oléophobe et hydrophobe des matériaux de construction tels que bétons, briques ou carreaux de terre cuite, grès, pierres naturelles, pavés de bois, céramiques1 plâtres et bitumes. Elle a plus particulièrement pour objet des compositions pour le traitement anfisalissure de sols réalisés avec ces matériaux.AQUEOUS COMPOSIONS FOR THE ANTI-SOUS TREATMENT OF
CONSTRUCTION MATERIALS
The present invention relates to the oleophobic and hydrophobic treatment of building materials such as concrete, bricks or terracotta tiles, sandstone, natural stones, wooden pavers, ceramics, plasters and bitumens. It relates more particularly to compositions for the anti-fouling treatment of floors made with these materials.

Pour conférer des propriétés oléophobes et hydrophobes aux matériaux de construction, on a déjà proposé l'application de divers produits, tels que des vernis acryliques ou des vernis polyuréthannes, ou des imprégnations a base d'huile végétale comme l'huile de lin, ou de silicones. Cependant, ces produits présentent tous des inconvénients. Ainsi, outre leur prix généralement élevé, les polyuréthannes doivent le plus souvent être appliqués en système bi-composant en milieu solvant avec un catalyseur ; ils modifient en outre considérablement l'aspect de surface du matériau traité et ne peuvent être appliqués ni sur bétons frais, ni sur supports mouillés. Les vernis acryliques ne présentant qu'un caractère hydrophobe sont d'une efficacité limitée.Les huiles végétales et les silicones s'utilisent en milieu solvant, ne peuvent pas être appliqués sur béton frais ou sur supports humides et ne confèrent pas de propriétés de résistance aux huiles ; d'autre part, les huiles végétales modifient aussi l'aspect de surface des matériaux traités. Enfin, aucun de ces produits ne confère aux supports un caractère autonettoyant. To impart oleophobic and hydrophobic properties to building materials, the application of various products has already been proposed, such as acrylic varnishes or polyurethane varnishes, or vegetable oil-based impregnations such as linseed oil, or of silicones. However, these products all have drawbacks. Thus, in addition to their generally high price, polyurethanes must most often be applied in a two-component system in a solvent medium with a catalyst; they also considerably modify the surface appearance of the treated material and cannot be applied either on fresh concrete or on wet substrates. Acrylic varnishes with only a hydrophobic character are of limited effectiveness. Vegetable oils and silicones are used in a solvent medium, cannot be applied on fresh concrete or on wet supports and do not confer resistance properties. oils; on the other hand, vegetable oils also modify the surface appearance of the treated materials. Finally, none of these products gives the supports a self-cleaning character.

II a maintenant été trouvé de nouvelles compositions aqueuses qui peuvent être facilement appliquées sur tout matériau de construction, sec ou humide, et qui, sans modifier notablement l'aspect de surface du matériau, lui confèrent après un temps de séchage frès court, à la fois des propriétés hydrofuges, oléofuges, antisalissures et autonettoyantes, stables au vieillissement et aux intempéries. New aqueous compositions have now been found which can be easily applied to any building material, dry or wet, and which, without appreciably modifying the surface appearance of the material, give it, after a short drying time, the both water-repellent, oil-repellent, anti-fouling and self-cleaning properties, stable to aging and weathering.

Les compositions selon l'invention comprennent en poids
(A) de 5 à 45 %, de préférence 10 à 25 %, d'une dispersion aqueuse d'un polymère ou copolymère non fluoré, le taux de matières sèches de cette dispersion pouvant aller de 30 à 60 %, de préférence 40 à 50 O/o ;
(B) de 2 a 20 %, de préférence 4 9 12 %, d'une dispersion aqueuse d'un copolymère acrylique fluoré, le taux de matières sèches de cette dispersion pouvant aller de 20 à 40 %, de préférence 25 à 30 %;;
(C) de 1 à 20 %, de préférence 1 915 %, d'une dispersion aqueuse d'un dérivé silicone ou d'une cire de polyéthylène, le taux de matières sèches de cette dispersion pouvant aller de 20 a 60 %, de préférence 30 à 45 %
(D) de 1 à 20 %, de préférence i 910 %, d'un stabilisant soluble dans l'eau
(E) de 0,5 à 8 %, de préférence 0,5 à 3 %, d'un agent de coalescence insoluble dans l'eau
et éventuellement de l'eau pour complément à 100 %, le taux de matières non volatiles ne devant pas dépasser 50 % et étant de préférence compris entre 5 et 20 %. The compositions according to the invention comprise by weight
(A) from 5 to 45%, preferably 10 to 25%, of an aqueous dispersion of a non-fluorinated polymer or copolymer, the dry matter content of this dispersion possibly ranging from 30 to 60%, preferably 40 to 50 O / o;
(B) from 2 to 20%, preferably 4 9 12%, of an aqueous dispersion of a fluorinated acrylic copolymer, the dry matter content of this dispersion possibly ranging from 20 to 40%, preferably 25 to 30% ;;
(C) from 1 to 20%, preferably 1,915%, of an aqueous dispersion of a silicone derivative or of a polyethylene wax, the dry matter content of this dispersion possibly ranging from 20 to 60%, preferably 30 to 45%
(D) from 1 to 20%, preferably i 910%, of a water-soluble stabilizer
(E) from 0.5 to 8%, preferably 0.5 to 3%, of a water-insoluble coalescing agent
and possibly water to make up to 100%, the level of non-volatile matter not to exceed 50% and preferably being between 5 and 20%.

Le constituant (A) est de préférence choisi parmi les dispersions aqueuses de polymères ou copolymères dérivés d'esters acryliques (par exemple, acrylates ou méthacrylates de méthyle, d'éthyle ou de butyle). Peuvent également être mentionnées les dispersions aqueuses de polyuréthannes et celles de polymères ou copolymères dérivés d'esters, halogénures ou éthers vinyliques (par exemple, acétate de vinyle, chlorure de vinyle ou de vinylidène, isobutyl vinyl éther), d'acides insaturés et leurs dérivés (par exemple, acide acrylique, acrylonitrile), du styrène et ses dérivés, ou d'hydrocarbures oléfiniques inférieurs (par exemple, butadiène). Component (A) is preferably chosen from aqueous dispersions of polymers or copolymers derived from acrylic esters (for example, methyl, ethyl or butyl acrylates or methacrylates). Mention may also be made of aqueous dispersions of polyurethanes and of polymers or copolymers derived from vinyl esters, halides or ethers (for example, vinyl acetate, vinyl or vinylidene chloride, isobutyl vinyl ether), of unsaturated acids and their derivatives (for example, acrylic acid, acrylonitrile), styrene and its derivatives, or lower olefinic hydrocarbons (for example, butadiene).

Le constituant (B) des compositions selon l'invention peut être choisi parmi toutes les dispersions aqueuses commerciales de copolymères acryliques fluorés. Ces dispersions sont généralement obtenues par copolymérisation en milieu aqueux d'au moins un acrylate ou méthacrylate d'alcool contenant une chaîne polyfluorée avec un ou plusieurs comonomères non fluorés tels que ceux précédemment cités, de préférence un ester acrylique. Component (B) of the compositions according to the invention can be chosen from all the commercial aqueous dispersions of fluorinated acrylic copolymers. These dispersions are generally obtained by copolymerization in aqueous medium of at least one alcohol acrylate or methacrylate containing a polyfluorinated chain with one or more non-fluorinated comonomers such as those mentioned above, preferably an acrylic ester.

Comme dérivés siliconés utilisables à titre de constituant (C), on peut mentionner plus spécialement les alkylalcoxysilanes (par exemple les mgthyl-, isobutyl-, isooctyl- ou phényl- trialcoxysilanes), les alkylalcoxysiloxanes (par exemple, les octyl-, isoctyl- ou tolyl-alcoxysiloxanes) ou des alkylsilicones (par exemple, les méthyl-silicones). As silicone derivatives which can be used as constituent (C), mention may more particularly be made of alkylalkoxysilanes (for example mgthyl-, isobutyl-, isooctyl- or phenyl-trialcoxysilanes), alkylalkoxysiloxanes (for example, octyl-, isoctyl- or tolyl-alkoxysiloxanes) or alkylsilicones (for example, methyl-silicones).

Les dispersions aqueuses (A), (B) et (C) utilisées pour préparer les compositions selon l'invention peuvent être de nature anionique, cationique ou non-ionique, mais elles doivent être choisies de façon à être compatibles entre elles. The aqueous dispersions (A), (B) and (C) used to prepare the compositions according to the invention can be of anionic, cationic or nonionic nature, but they must be chosen so as to be compatible with one another.

Comme stabilisant (D) soluble dans l'eau, on peut mentionner plus particulièrement les glycols comme l'éthylèneglycol, le propylèneglycol, la glycérine, les N-alkylpyrrolidones (par exemple la N-mgthyl-pyrrolidone), les aminoalcools comme la diéthanolamine ou la triéthanolamine, et les polyéthyléneglycols.  As water-soluble stabilizer (D), there may be mentioned more particularly glycols such as ethylene glycol, propylene glycol, glycerin, N-alkylpyrrolidones (for example N-mgthyl-pyrrolidone), amino alcohols such as diethanolamine or triethanolamine, and polyethylene glycols.

L'agent de coalescence, insoluble dans l'eau, peut être un dialkyl éther de l'éthylèneglycol (par exemple, le diéthyl ou dibutyl éther), I'hexylbneglycol, le monoisobutyrate de triméthyl - 2,2,4 pentanediol - 1,3.  The water-insoluble coalescing agent may be a dialkyl ether of ethylene glycol (for example, diethyl or dibutyl ether), hexylbneglycol, trimethyl monoisobutyrate - 2,2,4 pentanediol - 1, 3.

Si on le désire, les compositions selon l'invention peuvent également contenir divers additifs tels que des agents de conservation anticryptogamiques ou fongicides comme, par exemple, le pentachlorophénate de sodium, l'acétate de phénylmercure, l'orthophénylphénate de sodium, le dodiécylsuccinate de phénylmercure et les chlorocrésols, ainsi des colloTdes protecteurs comme, par exemple, les acides polyacryliques, les polyalcools vinyliques, les dérivés cellulosiques et les polyvinylpyrrolidones. If desired, the compositions according to the invention may also contain various additives such as anticryptogamic or fungicidal preservatives such as, for example, sodium pentachlorophenate, phenylmercury acetate, sodium orthophenylphenate, dodiecylsuccinate phenylmercury and chlorocresols, as well as protective colloTdes such as, for example, polyacrylic acids, polyvinyl alcohols, cellulose derivatives and polyvinylpyrrolidones.

Bien qu'elles puissent être appliquées à des supports en élévation, les propriétés des compositions selon l'invention les destinent plus spécialement à la protection des sols intérieures ou extérieurs à usage particulier ou collectif tels que sous-sols, garages, places urbaines, rues piétonnes, parkings, etc...  Although they can be applied to supports in elevation, the properties of the compositions according to the invention more specifically make them suitable for the protection of interior or exterior floors for particular or collective use such as basements, garages, urban squares, streets pedestrian, parking, etc ...

Les compositions selon l'invention peuvent notamment être appliquées sur des bétons coulés en place (talochés lisses, dgsactivgs, bouchardés. balayes, acidés ou sablés). sur des éléments préfabriqués (pavés autobloquants mono- ou bicouches, colorés ou non,à granulats apparents ou non),sur des dalies vibrées ou pressées, lisses ou à granulats apparents ou bouchardées, sablées ou acidées. The compositions according to the invention can in particular be applied to concretes cast in place (smooth floats, dgsactivgs, bush hammered. Sweeps, acid or sanded). on prefabricated elements (self-locking pavers, monolayer or bilayer, colored or not, with visible aggregates or not), on vibrated or pressed dalies, smooth or with visible aggregates or bush hammered, sandblasted or acidic.

L'application des compositions selon l'invention peut se faire en une ou plusieurs couches suivant les techniques bien connues en soi, par exemple par pulvérisation, immersion, étendage à la brosse ou au rouleau, de façon 9 déposer de 50 à 800 g de composition selon l'invention par m2 de surface à traiter, de préférence 200 à 400 g/m2. The application of the compositions according to the invention can be carried out in one or more layers according to techniques well known per se, for example by spraying, immersion, spreading by brush or roller, so as to deposit from 50 to 800 g of composition according to the invention per m2 of surface to be treated, preferably 200 to 400 g / m2.

Les exemples suivants dans lesquels les parties sont exprimées en poids, illustrent l'invention sans la limiter. The following examples in which the parts are expressed by weight, illustrate the invention without limiting it.

EXEMPLE 1
Sous agitation et à température ambiante, on mélange les ingrédients suivants
-15 parties d'une dispersion aqueuse anionique à 40 % d'un copolymère 70/30 de méthacrylate de butyle et de méthacrylate d'éthyle
-10 parties d'une dispersion aqueuse anionique à 30 % d'un copolymère 50/40/10 de méthacrylate de sulfamidoalcool polyfluoré, de méthacrylate d'heptyle et de méthacrylate de butyle
-10 parties d'une dispersion aqueuse non ionique d'un méthylalcoxysiloxane à 40 % de matières sèches
-5 parties de propylèneglycol
-0,9 partie de monoisobutyrate de triméthyl -2,2,4 pentanediol -1,3
-0,5 partie de dodécylsuccinate de phénylmercure
-58,6 parties d'eau.EXAMPLE 1
With stirring and at room temperature, the following ingredients are mixed
-15 parts of an anionic aqueous dispersion at 40% of a 70/30 copolymer of butyl methacrylate and ethyl methacrylate
-10 parts of an anionic aqueous dispersion at 30% of a 50/40/10 copolymer of polyfluorinated sulfamidoalcohol methacrylate, heptyl methacrylate and butyl methacrylate
-10 parts of a nonionic aqueous dispersion of a methylalkoxysiloxane with 40% dry matter
-5 parts of propylene glycol
-0.9 part of trimethyl monoisobutyrate -2.2.4 pentanediol -1.3
-0.5 part of phenylmercury dodecylsuccinate
-58.6 parts of water.

La composition ainsi obtenue est appliquée sur un sol de béton à
granulats apparents à raison de 250 glm2 par puivgerisation en une couche, puis
on laisse sécher 24 heures à température ambiante.The composition thus obtained is applied to a concrete floor to
apparent aggregates at the rate of 250 glm2 by spraying in a layer, then
allowed to dry for 24 hours at room temperature.

Le sol ainsi traité est alors volontairement souillé avec de l'huile de
vidange, puis on y laisse circuler des véhicules pendant 15 jours. On lave alors
au jet d'eau à la pression ordinaire de distribution du réseau urbain, puis on
laisse sécher. Après 4 purs, on constate qu'il ne reste ni tâche ni auréole et que
le sol a recouvré son aspect d'origine. II en est de même lorsque le sol traité et
souillé subit l'effet d'une pluie d'orage. The soil thus treated is then voluntarily soiled with oil
emptying, then vehicles are allowed to circulate there for 15 days. We wash then
with the jet of water at the ordinary distribution pressure of the urban network, then we
let dry. After 4 pure, we see that there is no stain or halo left and that
the ground has recovered its original appearance. It is the same when the treated soil and
soiled undergoes the effect of a thunderstorm rain.

EXEMPLE2
On opère comme à l'exemple 1, mais avec les ingrédients suivants:
-25 parties d'une dispersion aqueuse à 40 % d'un polyuréthanne aliphatique sur base polyester
-8 parties de la même dispersion aqueuse de copolymère fluoré qu'à l'exemple 1
-5 parties d'une dispersion aqueuse non-ionique de cire de polyéthylène (extrait sec : 35 %)
-5 parties de diéthylèneglycol
-1,5 partie d'hexylèneglycol
-55,5 parties d'eau.EXAMPLE 2
The procedure is as in Example 1, but with the following ingredients:
-25 parts of an aqueous dispersion at 40% of an aliphatic polyurethane on polyester base
-8 parts of the same aqueous dispersion of fluorinated copolymer as in Example 1
-5 parts of a nonionic aqueous dispersion of polyethylene wax (dry extract: 35%)
-5 parts of diethylene glycol
-1.5 parts of hexylene glycol
-55.5 parts of water.

La composition ainsi obtenue est appliquée comme à l'exemple 1 sur un sol de pierre naturelles. Ce sol est ensuite souillé avec de l'huile de vidange, puis laissé à la circulation pendant 2 jours. Après nettoyage au jet d'eau comme à l'exemple 1, le sol a recouvré son aspect initial.  The composition thus obtained is applied as in Example 1 to a natural stone floor. This soil is then soiled with drain oil, then left for circulation for 2 days. After cleaning with a water jet as in Example 1, the floor has recovered its initial appearance.
