1 1

La présente invention concerne un procédé de protection d'une surface à bâtir contre les insectes, notamment les termites. La protection antitermites du bâti avant construction est actuellement classiquement effectuée suite à l'utilisation des procédés suivants : l'aspersion, la pulvérisation ou l'épandage de produits liquides contenant une dose d'agent insecticide. Un autre procédé existant consiste à dérouler sur la surface à protéger des lés d'un film polymère auquel est intégré un agent insecticide. The present invention relates to a method of protecting a building surface against insects, including termites. The antitermite protection of the frame before construction is currently conventionally carried out following the use of the following methods: spraying, spraying or spreading liquid products containing a dose of insecticidal agent. Another existing method consists in unrolling on the surface to be protected strips of a polymer film in which an insecticidal agent is integrated.

Ces différents procédés ne donnent toutefois pas entière satisfaction, en particulier en ce qui concerne la protection de l'environnement et la sécurité du personnel chargé de leur mise en oeuvre. De surcroît, le décret du 27 juin 2006 relatif à l'application des articles R112.2 et R112.4 du Code de la construction et de l'habitation réglemente la protection du bâti contre leur infectation par les termites. Ce décret définit les types de procédés qui doivent être utilisés pour la protection du bâti, par une barrière physique, physicochimique ou de contrôle et rend non conforme le traitement du sol par pulvérisation directe d'insecticide. However, these various methods are not entirely satisfactory, in particular with regard to the protection of the environment and the safety of the personnel responsible for their implementation. In addition, the decree of June 27, 2006 relating to the application of articles R112.2 and R112.4 of the Construction and Housing Code regulates the protection of buildings against their infection by termites. This decree defines the types of processes that must be used for the protection of the building, by a physical, physicochemical or control barrier and makes the treatment of the soil by direct spraying insecticide.

La présente invention a pour objectif de proposer un procédé permettant d'obtenir une protection efficace contre les termites dans le respect de cette nouvelle réglementation. Ce procédé doit en outre permettre d'effectuer le traitement des surfaces à bâtir par temps froid et humide, voire par temps de pluie. The present invention aims to provide a method for obtaining effective protection against termites in accordance with this new regulation. This method must also make it possible to perform the treatment of building surfaces in cold and wet weather, or even in rainy weather.

A cet effet, l'invention propose un procédé de protection d'une surface à bâtir contre les insectes en particulier contre les termites caractérisé en ce que l'on applique sur la surface à protéger, de préférence par pulvérisation, un mortier à base de ciment renfermant un agent insecticide. Selon l'invention, on entend par mortier un mélange renfermant un liant hydraulique susceptible de faire prise en présence d'eau. Selon l'invention, on peut à titre d'exemple non limitatif avoir recours aux insecticides suivants : la bifenthrine, le chlorfénapyr, le fipronil ou la permethrine. Cet agent insecticide peut éventuellement être directement incorporé au mortier sous sa forme liquide ; une telle incorporation pré-sente toutefois l'inconvénient que l'agent insecticide risque d'être facile-ment extrait après application par l'humidité du sol. For this purpose, the invention proposes a method of protecting a building surface against insects, in particular against termites, characterized in that a surface-based mortar is applied to the surface to be protected, preferably by spraying. cement containing an insecticidal agent. According to the invention, mortar means a mixture containing a hydraulic binder capable of setting in the presence of water. According to the invention, the following insecticides can be used as non-limiting examples: bifenthrin, chlorfenapyr, fipronil or permethrin. This insecticidal agent can optionally be directly incorporated into the mortar in its liquid form; such incorporation, however, has the disadvantage that the insecticidal agent may be easily extracted after application by soil moisture.

Pour remédier à cet inconvénient, on peut, selon une autre caractéristique de l'invention, adsorber l'agent insecticide sur un support solide pulvérulent puis incorporer le support porteur de l'agent insecticide au mortier. To overcome this drawback, it is possible, according to another characteristic of the invention, to adsorb the insecticidal agent on a solid powdery support and then to incorporate the carrier carrying the insecticidal agent in the mortar.

Les supports solides pulvérulents pouvant être utilisés à cet effet sont les matériaux minéraux conventionnels connus tels que les kaolins, les argiles, les silices précipitées et pyrogénées, les terres de diatomées, ou encore les zéolithes. Selon une autre caractéristique de l'invention, on peut éga- lement encapsuler l'agent insecticide dans un agent d'encapsulation puis incorporer cet agent d'encapsulation porteur de l'insecticide dans le mortier. Parmi les agents d'encapsulation pouvant être mis en oeuvre conformément à l'invention, on peut à titre d'exemple citer les cyclo-15 dextrines ou les calix-arènes. L'agent insecticide peut également être encapsulé dans une pellicule de polymère, par les méthodes d'encapsulation connues. Les mortiers mis en oeuvre conformément à l'invention peu-vent être réalisés à l'aide de ciment Portland conventionnel ou encore à 20 l'aide de ciments alumineux ou encore à partir de mélanges binaires (mélanges de ciment Portland et de ciment alumineux) ou de mélanges ternaires (mélanges de ciment Portland, de ciment alumineux et de sulfate de calcium). Le temps de prise de ces mortiers peut être réglé entre quel- 25 ques minutes et plusieurs heures en fonction du système utilisé. Dans le cas d'un mortier à base de ciment Portland, le temps de prise est en règle générale de quelques heures. Selon une autre caractéristique de l'invention permettant de réduire ce temps de prise, on peut ajouter au mortier au moins un agent 30 accélérateur de prise. Cet agent accélérateur de prise peut avantageusement être constitué par du carbonate de lithium auquel on peut éventuellement ajouter du bicarbonate de sodium. Dans le cas d'un ciment alumineux ou d'un mélange binaire 35 ou ternaire renfermant un tel agent accélérateur de prise, le temps de prise peut être réduit jusqu'à environ 2 mn. Les mortiers mis en oeuvre conformément à l'invention peu-vent bien entendu également contenir des additifs usuels tels que par The solid powdery supports that can be used for this purpose are known conventional mineral materials such as kaolins, clays, precipitated and fumed silicas, diatomaceous earths or even zeolites. According to another characteristic of the invention, it is also possible to encapsulate the insecticidal agent in an encapsulating agent and then to incorporate this encapsulating agent carrying the insecticide into the mortar. Among the encapsulating agents that can be used according to the invention, mention may be made, for example, of cyclo-dextrins or calix-arenes. The insecticidal agent may also be encapsulated in a polymer film by known encapsulation methods. The mortars used according to the invention can be made using conventional Portland cement or alternatively with aluminous cements or from binary mixtures (mixtures of Portland cement and aluminous cement). or ternary mixtures (mixtures of Portland cement, aluminous cement and calcium sulphate). The setting time of these mortars can be set between a few minutes and several hours depending on the system used. In the case of a Portland cement-based mortar, setting time is usually a few hours. According to another characteristic of the invention making it possible to reduce this setting time, at least one setting accelerating agent may be added to the mortar. This setting accelerating agent may advantageously consist of lithium carbonate to which sodium bicarbonate may optionally be added. In the case of aluminous cement or a binary or ternary mixture containing such a setting accelerating agent, setting time can be reduced to about 2 minutes. The mortars used according to the invention can, of course, also contain conventional additives such as

exemple du sable, des silices fines, des fillers calcaires, des agents épaississants, des agents fluidifiants, des agents antimousse, des polymères pulvérulents ou sous forme de dispersion aqueuse, ainsi que toutes les matières premières classiquement utilisées dans le domaine du bâtiment. sand, fine silicas, calcareous fillers, thickening agents, fluidifying agents, antifoam agents, pulverulent polymers or in the form of an aqueous dispersion, as well as all the raw materials conventionally used in the construction field.

Selon une autre caractéristique de l'invention, les polymères en dispersion aqueuse ajoutés au mortier sont choisis dans le groupe formé par les polymères ou copolymères acryliques, styrène-acryliques, ou vinyliques, compatibles avec les liants hydrauliques. Il sont alors formulés sous forme de composition aqueuse pouvant comprendre également des agents de conformation tels que par exemple des agents de dispersion, des charges, des pigments, des agents antimousse, des agents épaississants ainsi que toutes les matières premières utilisées par l'homme de métier dans le domaine du bâtiment. Selon une caractéristique avantageuse de l'invention la composition aqueuse selon l'invention comprend en proportions pondéra-les de 10 à 40 % de polymère en dispersion calculé en matière sèche, de 0 à 70% d'eau, de 0 à 70 % de charges minérales, de 0 à 1 % d'agents dispersants, de 0 à 1 % d'agents antimousse, de 0 à 5 % d'agents de coalescence, de 0,2 à 5 % d'agents épaississants, et de 0 à 0,5 % d'agents mouillants. According to another characteristic of the invention, the aqueous dispersion polymers added to the mortar are chosen from the group formed by acrylic, styrene-acrylic or vinyl polymers or copolymers compatible with hydraulic binders. They are then formulated in the form of an aqueous composition which may also comprise conforming agents such as, for example, dispersing agents, fillers, pigments, antifoaming agents, thickening agents and all the raw materials used by the man of the invention. profession in the field of building. According to an advantageous characteristic of the invention, the aqueous composition according to the invention comprises, in weighted proportions, from 10 to 40% of dispersed polymer calculated as dry matter, from 0 to 70% of water, from 0 to 70% of mineral fillers, 0 to 1% dispersing agents, 0 to 1% antifoaming agents, 0 to 5% coalescing agents, 0.2 to 5% thickening agents, and 0 to 0.5% wetting agents.

L'insecticide peut alors être incorporé également dans la composition polymérique. L'application du mortier selon le procédé conforme à l'invention est extrêmement simple : en effet, lorsque la surface à traiter est humide, il suffit à cet effet de répandre le mortier sous forme pulvéru- lente sur cette surface pour qu'il fasse prise après la durée impartie. Dans le cas d'un temps sec, on peut, selon une autre caractéristique de l'invention, arroser la surface à protéger avec de l'eau avant d'appliquer le mortier renfermant un agent insecticide de façon à permettre la prise. The insecticide can then be incorporated into the polymeric composition as well. The application of the mortar according to the process according to the invention is extremely simple: in fact, when the surface to be treated is wet, it suffices for this purpose to spread the mortar in powder form on this surface so that it makes taken after the time given. In the case of a dry weather, it is possible, according to another characteristic of the invention, to water the surface to be protected with water before applying the mortar containing an insecticidal agent so as to allow setting.

Dans le cas de l'utilisation d'une composition polymérique en dispersion aqueuse, la surface à protéger est arrosée à l'aide de la composition polymérique avant d'appliquer le mortier. Le mortier peut être appliqué également avant la composition polymérique. La composition po- In the case of the use of a polymeric composition in aqueous dispersion, the surface to be protected is sprayed with the aid of the polymeric composition before applying the mortar. The mortar can be applied also before the polymeric composition. The composition

lymérique est alors pulvérisée sur la couche de mortier pulvérulent pour permettre la prise. L'agent insecticide peut être incorporé indifféremment au mortier ou à la composition polymérique. The polymer is then sprayed onto the powdery mortar layer to allow setting. The insecticidal agent may be incorporated indifferently in the mortar or in the polymeric composition.

L'application peut être réalisée à des températures très bas-ses, proches de 0°C, à la condition que l'eau ne soit pas gelée. Lorsque la durée de prise a été réglée à quelques minutes, le mortier peut être sollicité mécaniquement tout de suite après sa prise, et ne peut pas être endommagé par exemple lors d'un orage. The application can be carried out at very low temperatures, close to 0 ° C, provided that the water is not frozen. When the setting time has been set to a few minutes, the mortar can be mechanically stressed immediately after its setting, and can not be damaged for example during a storm.

La protection de la surface à bâtir est alors achevée, et il est possible de procéder au coulage de dalles de béton sur cette surface immédiatement après ou quelques jours plus tard. Selon l'invention, le mortier peut également être gâché en continu à l'aide d'une machine à projeter ou guniteuse dans laquelle l'eau est amenée directement dans la buse de la machine juste avant projection du mortier afin d'éviter la prise et le durcissement de la composition dans les tuyauteries de la machine. Dans le cas d'une composition dont le temps de prise est réglé à 1 heure environ le gâchage peut s'effectuer dans une machine con- ventionnelle comportant une première partie dans laquelle la poudre est mélangée à l'eau puis une seconde partie dans laquelle le coulis obtenu est pompé puis projeté à l'aide d'air comprimé. L'utilisation de telles machines présente l'avantage de per-mettre d'appliquer le mortier sur des surfaces inclinées ou verticales. The protection of the building surface is then completed, and it is possible to proceed to the pouring of concrete slabs on this surface immediately after or a few days later. According to the invention, the mortar can also be tempered continuously using a spraying machine or guniteuse in which the water is fed directly into the nozzle of the machine just before the mortar is sprayed in order to avoid the setting and hardening of the composition in the pipework of the machine. In the case of a composition whose setting time is set to about 1 hour, the mixing can be carried out in a conventional machine comprising a first part in which the powder is mixed with water and then a second part in which the grout obtained is pumped and then sprayed with compressed air. The use of such machines has the advantage of permitting the application of the mortar on inclined or vertical surfaces.
