Description

La présente invention concerne un produit de démoulage pour les liants hydrauliques tels que les bétons par exemple.The present invention relates to a mold release product for hydraulic binders such as concrete for example.

Il est connu dans le moulage des pièces en béton par exemple d'enduire les surfaces des moules venant au contact avec le matériau de moulage d'un produit qui facilite le démoulage et permette d'obtenir un état de surface des pièces satisfaisants.It is known in the molding of concrete parts for example to coat the surfaces of the molds coming into contact with the molding material with a product which facilitates demolding and makes it possible to obtain a satisfactory surface condition of the parts.

Les produits de démoulage actuellement utilisés sont essentiellement constitués suivant différentes formulations d'un mélange de solvants et de produits pétroliers auxquels sont ajoutés des principes actifs de démoulage.The mold release products currently used consist essentially of different formulations of a mixture of solvents and petroleum products to which are added mold release active ingredients.

Il est également proposé des émulsions plus ou moins stables dans le temps comportant des pourcentages de produits pétroliers.Emulsions more or less stable over time are also proposed, comprising percentages of petroleum products.

Le recours à des produits pétroliers est générateur d'un accroissement de coût des dits produits de démoulage.The use of petroleum products generates an increase in the cost of said mold release products.

En outre, la présence dans les dits produits de solvants et d'huiles pétrolières rend necessaire un temps de séchage des surfaces démoulées avant toute autre opération de traitement des dites surfaces, telles que par exemple l'application de peintures qui en l'absence de séchage n'adhéreraient pas aux dites surfaces.In addition, the presence in said products of solvents and petroleum oils makes it necessary to dry the molded surfaces before any other treatment operation on said surfaces, such as for example the application of paints which in the absence of drying would not adhere to said surfaces.

La présente invention vise à obvier aux inconvénients ci-dessus en réalisant un produit de démoulage qui ne comporte pas de produits pé- traliers.The present invention aims to overcome the above drawbacks by producing a mold release product which does not include petroleum products.

A cet effet, le produit selon la présente invention de démoulage pour liants hydrauliques se caractérise essentiellement en ce qu'il est constitué par la combinaison d'au moins un principe actif de démoulage qui est un sel d'acide organique et/ou au moins un agent clarifiant antigel, qui est un hydroxy-ethyl-ether et/ou d'au moins un agent d'étalement qui peut être un ester et/ou d'au moins un agent d'onctuosité constitué de polymères solubles dans l'eau et d'un véhicule qui est de l'eau, les proportions de la combinaison ci-dessus étant variables, notamment celles du véhicule, selon la concentration souhaitée des produits obtenus qui se caractérisent en ce qu'ils sont des solutions acqueuses, limpides, résistantes au gel et stables dans le temps.To this end, the mold release product according to the present invention for hydraulic binders is essentially characterized in that it consists of the combination of at least one mold release active principle which is an organic acid salt and / or at least an antifreeze clarifying agent, which is a hydroxyethyl ether and / or at least one spreading agent which can be an ester and / or at least one oil -iness agent consisting of water-soluble polymers and of a vehicle which is water, the proportions of the above combination being variable, in particular those of the vehicle, according to the desired concentration of the products obtained which are characterized in that they are aqueous, clear solutions, frost resistant and stable over time.

La lecture de la description ci-après d'une forme préférée et non limitative de l'invention dans laquelle les proportions et pourcentages sont donnés à titre non limitatif permettra de mieux comprendre l'invention.Reading the description below of a preferred and non-limiting form of the invention in which the proportions and percentages are given without limitation will allow a better understanding of the invention.

Comme énoncés les produits de démoulage à l'eau selon l'invention se composent de la combinaison d'un principe actif de démoulage qui a pour but le décollement des pièces fabriquées des parois du moule,d'un agent clarifiant antigel qui vient compléter la solubilité du principe actif et par augmentation de son dosage assurer la tenue au gel,d'un agent d'étalement permettant après application, lors du séchage la formation d'un film uniforme sur les parois du moule, d'un agent d'onctuosité qui coopère avec le précédent pour assurer une certaine épaisseur du film et sa continuité et d'un véhicule.As stated water-release agents according to the invention consist of the combination of an active ingredient release which has b ut the separation of the manufactured parts of the mold walls, of a clarifying agent antifreeze which complements the solubility of the active principle and by increasing its dosage ensure the resistance to freezing, of a spreading agent allowing after application, during drying, the formation of a uniform film on the walls of the mold, of a oiliness which cooperates with the previous one to ensure a certain thickness of the film and its continuity and of a vehicle.

Le principe actif de démoulage est un sel d'acide organique. La partie cathionique du sel est une base qui peut être par exemple la soude, la potasse, l'ammoniaque, les amines ou leurs dérivés.The active release agent is an organic acid salt. The cathionic part of the salt is a base which can be, for example, soda, potash, ammonia, amines or their derivatives.

Suivant une forme préférée de l'invention, l'ammoniaque a été choisie en raison de la bonne solubilité des sels obtenus, de l'absence d'effets secondaires néfastes sur l'action du produit final, tels que retard de prise du liant en surface ou poudrage.According to a preferred form of the invention, the ammonia was chosen because of the good solubility of the salts obtained, the absence of harmful side effects on the action of the final product, such as delay in setting of the binder in surface or dusting.

En outre, l'ammoniaque présente l'avantage d'un dégagement de gaz ammoniac lors de la saponification par l'ion calcium présent dans l'eau de gachage, le dit gaz ammoniac apportant une aide au démoulage.In addition, ammonia has the advantage of giving off ammonia gas during saponification by the calcium ion present in the mixing water, the said ammonia gas providing a release aid.

La partie anionique du sel d'acide organique est constituée par un ou des acides organiques du groupe des acides carboxylique ne renfermant pas plus d'une fonction hydroxyle par molécule.The anionic part of the organic acid salt consists of one or more organic acids from the group of carboxylic acids not containing more than one hydroxyl function per molecule.

Suivant une préférence on utilise des acides hydrocarbonés saturés ou non à chaîne linéaire, ramifiées ou cyclique contenant au moins cinq atomes de carbone et de préférence de dix à trente.According to a preference, saturated or unsaturated straight chain, branched or cyclic hydrocarbon acids containing at least five carbon atoms and preferably from ten to thirty are used.

Ces acides peuvent être des acides héxanoïques, décanoïques cyclohexyl carboxylique , naphténiques, néodécanoiques, abiétiques, dodécanoiques, myristiques, capryliques, oléïques, palmitiques, pélargomiques, unde- cylique, versatiques.These acids can be hexanoic, decanoic cyclohexyl carboxylic, naphthenic, neodecanoic, abietic, dodecanoic, myristic, caprylic, oleic, palmitic, pelargomic, unde-cylic, versatic acids.

L'agent d'étalement peut également être choisi parmi les ester hydroxyles et/ou ethoxyles.The spreading agent can also be chosen from hydroxyl and / or ethoxy esters.

Le choix est effectué de préférence en tenant compte de l'incidence la plus réduite présentée par le composé au niveau de l'effet retardateur de la prise sur le liant.The choice is preferably made taking into account the most reduced incidence presented by the compound at the level of the delay-setting effect on the binder.

Les essais effectués ont démontré que l'utilisation d'un ether permettait les meilleurs résultats.Tests have shown that using an ether provides the best results.

L'ester choisi comme agent d'étalement est un dérivé d'un polyol tel que par exemple, glycérine, triméthylolpropane , pentaerythritol, etc..., qui est partiellement esterifié par un mono ou un diacide gras organique.The ester chosen as spreading agent is a derivative of a polyol such as, for example, glycerin, trimethylolpropane, pentaerythritol, etc., which is partially esterified with a mono or an organic fatty diacid.

La ou les fonctions hydroxyles libres du polyol seront ethoxylées de façon à assurer une solubilité limitée du produit dans l'eau.The free hydroxyl function (s) of the polyol will be ethoxylated so as to ensure a limited solubility of the product in water.

L'agent d'onctuosité est constitué de polymères solubles à l'eau. Ce peut être des dérivés cellulosiques tels que :

  • - hydroxy - ethyl - ether,
  • - methoxy - ether
  • - carboxy - methyl etc...
The oiliness agent consists of water-soluble polymers. It can be cellulose derivatives such as:

Ce peut être des polysaccharides linéaires ou un polyglycol à très haut poids moléculaire.They can be linear polysaccharides or a very high molecular weight polyglycol.

Le critère de choix du produit est celui de la plus faible action retardatrice sur la prise du liant hydraulique combiné avec le meilleur effet de lubrification.The criterion for choosing the product is that of the weakest delaying action on the setting of the hydraulic binder combined with the best lubrication effect.

De préférence, en sorte de donner au produit de démoulage une viscosité comprise entre un et deux degrés de l'échelle d'Engler, on utilise un polyglycol de longueur de chaîne très élevée qui a donné les meilleurs résultats au cours des essais effectués.Preferably, so as to give the demolding product a viscosity of between one and two degrees of the Engler scale, a very long chain length polyglycol is used which has given the best results during the tests carried out.

Le choix du véhicule qui est l'eau est conditionné par son faible prix. rThe choice of vehicle which is water is conditioned by its low price. r

Si l'eau a un degré de dureté trop fort par présence de calcium celle-ci peut être masquée par adjonction d'un agent à capacité sequestran- te tel que ethylènediaminetetracetique ou acide nitrilotriacetique, etc...If the water has a too high degree of hardness by the presence of calcium, this can be masked by adding an agent with sequestering capacity such as ethylenediaminetetracetic or nitrilotriacetic acid, etc.

Le dosage de l'agent sequestrant s'effectue à la quantité limite pour masquer le calcium présent dans l'eau en sorte qu'il ne modifie en rien les propriétés finales de la composition.The dosage of the sequestering agent is carried out at the limit quantity to mask the calcium present in the water so that it in no way modifies the final properties of the composition.

L'absence de ces agents peut necessiter un surcroît d'agent clarifiant et leur excès peut entraîner un retard du durcissement du liant en surface ou même un poudrage.The absence of these agents may require an additional clarifying agent and their excess may result in a delay in the hardening of the binder on the surface or even in powdering.
