Description
Composition comprenant un alkylsiliconate hydrophobant contenant au moins un indicateurComposition comprising a hydrophobic alkylsiliconate containing at least one indicator
INTRODUCTIONINTRODUCTION
La présente invention a pour objet une composition comprenant un alkylsiliconate hydrophobant contenant au moins un indicateur.The present invention relates to a composition comprising a hydrophobic alkylsiliconate containing at least one indicator.
Il est déjà connu de rendre hydrophobe un substrat avec une composition à base de méthylsiliconate, par exemple selon le brevet EP 889' 109. Selon le brevet EP l'253'178, une autre solution pour hydrophober un substrat consiste à traiter avec un mélange de méthylsiliconate de sodium ou de potassium et de silicate de sodium ou de potassium. Afin de disposer d'une préparation stable au stockage, elles doivent être stabilisées par un fort excès moléculaire d'agent alcalin. La solution alcaline est appliquée à la surface du sol par voie topique, s'il s'agit de faire un traitement in-situ, ou encore de mélanger ladite préparation à un substrat granulaire dans un mélangeur solide/liquide. Les surfaces traitées humides sont exposées au séchage à l'air ambiant. Au cours de cette étape, une modification de l'alcalinité à lieu (diminution du pH) suite au phénomène de la carbonatation, c-à.d. par l'absorption du gaz carbonique ambiant provoquant ainsi la polymérisation du principe actif. La préparation commercialisée est un concentré stabilisé, laquelle est fortement diluée avant application. Il est apparu que tant la solution concentrée, stockée dans des récipients insuffisamment étanches que les solutions diluées lors des applications sur le terrain perdent leur
activité hydrophobantes suite à une polymérisation induite spontanément suite à la carbonatation. Ce phénomène est à éviter soigneusement pour assurer l'efficacité du traitement.It is already known to render a substrate hydrophobic with a composition based on methylsiliconate, for example according to patent EP 889 109. According to EP 253'178, another solution for hydrophobing a substrate consists in treating with a mixture sodium or potassium methylsiliconate and sodium or potassium silicate. In order to have a stable storage preparation, they must be stabilized by a high molecular excess of alkaline agent. The alkaline solution is topically applied to the surface of the soil, if it is to do an in-situ treatment, or to mix said preparation with a granular substrate in a solid / liquid mixer. Moistened treated surfaces are exposed to drying in ambient air. During this step, a modification of the alkalinity takes place (decrease in pH) following the phenomenon of carbonation, i.e. by the absorption of ambient carbon dioxide thus causing the polymerization of the active ingredient. The marketed preparation is a stabilized concentrate, which is highly diluted before application. It appeared that both the concentrated solution, stored in insufficiently sealed containers and diluted solutions during field applications, lose their hydrophobic activity following spontaneously induced polymerization following carbonation. This phenomenon is to be avoided carefully to ensure the effectiveness of treatment.

EXEMPLESEXAMPLES
EXEMPLE 1EXAMPLE 1
Une préparation industrielle A composée de 28% méthylsiliconate, 19% d'hydroxyde de potassium et 53% d'eau est utilisée communément pour l'imperméabilisation des fondations en génie civil ou comme agent hydrophobant en agriculture pour améliorer le rendement d'eau d'irrigation. Son pH à l'origine est de 13,8. Abandonnée dans un récipient ouvert, une chute du pH lent et progressive est observée suite à la carbonatation du gaz carbonique atmosphérique. A partir de pH 9 à 10, un dépôt commence à se former et une phase solide apparaît, indiquant une perte en matière active.An industrial preparation A composed of 28% methylsiliconate, 19% potassium hydroxide and 53% water is commonly used for the waterproofing of foundations in civil engineering or as a hydrophobic agent in agriculture to improve the water yield of irrigation. Its pH at the origin is 13.8. Abandoned in an open container, a slow and progressive pH drop is observed following the carbonation of atmospheric carbon dioxide. From pH 9 to 10, a deposit begins to form and a solid phase appears, indicating a loss of active material.
Si l'on ajoute à la préparation 20ppm (20mg par litre de solution A) de thymolphtaléine (CA Nr 125-20-2), la coloration bleue intense disparaît avant la formation de phase solide, indiquant l'induction de la dégradation de préparation.
EXEMPLE 2When 20 mg of Thymolphthalein (20 ml per 20 ml of solution A) is added to the preparation, the intense blue color disappears before solid phase formation, indicating the induction of the degradation of the preparation. . EXAMPLE 2
Une solution 1% de A de l'exemple 1, ne contenant pas de colorant telle appliquée en agriculture est abandonnée pendant 1 jour dans le réservoir de 1 ' applicateur . Bien que l'aspect de la dilution soit inchangé, les prestations hydrophobantes sont insuffisantes pour l'application. Par contre, si l'adjonction de la thymolphtaléine a été effectuée, la coloration bleue intense initiale a disparu, signalant la perte d'efficacité de la préparation.A solution 1% of A of Example 1, containing no such dye applied in agriculture is abandoned for 1 day in the reservoir of 1 applicator. Although the appearance of the dilution is unchanged, the hydrophobic benefits are insufficient for the application. On the other hand, if the addition of the thymolphthalein was carried out, the initial intense blue color disappeared, signaling the loss of effectiveness of the preparation.
EXEMPLE 3EXAMPLE 3
A la solution industrielle A de l'exemple 1, on ajouteWith the industrial solution A of example 1, we add
20ppm de thymolphtaléine et 20ppm de rouge de méthyle (CA Nr 493-52-7) , soit 20mg de chaque indicateur /L, on dispose d'une solution verte, indiquant la parfaite réactivité de la préparation.20 ppm of thymolphthalein and 20 ppm of methyl red (CA No. 493-52-7), ie 20 mg of each indicator / L, a green solution is available, indicating the perfect reactivity of the preparation.
Cette solution est diluée à environ 1-2% avec de l'eau en vue de l'application, la rendant très vulnérable à la chute de pH par carbonatation.This solution is diluted to about 1-2% with water for application, making it very vulnerable to pH drop by carbonation.
Abandonnée à l'atmosphère ambiante, la couleur verte originale disparaît et laisse place à la couleur jaune provenant du rouge de méthyle en milieu alcalin: la préparation est à la limite de la tolérance d'application. Si le séjour dans la cuve exposée continue, on observe après un certain temps l'apparition de la couleur rouge, indiquant la perte totale d'efficacité du méthyl- siliconate.
Abandoned to the ambient atmosphere, the original green color disappears and gives way to the yellow color coming from methyl red in an alkaline medium: the preparation is at the limit of the application tolerance. If the residence in the exposed tank continues, the appearance of the red color is observed after a certain time, indicating the total loss of effectiveness of the methyl siliconate.
