Description
« Procédé pour la protection contre les insectes, notamment les termites des surfaces à bâtir » "Method for protection against insects, especially termites of building surfaces"
La présente invention concerne un procédé pour la protection contre les insectes, notamment les termites des surfaces à bâtir. Actuellement, la protection antitermites du bâti avant construction est réalisée par l'utilisation des méthodes suivantes : l'aspersion, la pulvérisation ou l'épandage de produits liquides contenant une dose d'insecticide.The present invention relates to a method for protection against insects, including termites of building surfaces. Currently, the antitermite protection of the frame before construction is achieved by the use of the following methods: sprinkling, spraying or spreading liquid products containing a dose of insecticide.
Une autre méthode existe consistant à dérouler un film dont les lés sont préexistants et auquel est intégré un insecticide.Another method is to unroll a film with pre-existing strips and an insecticide.
Le décret du 27 juin 2006 relatif à l'application des articles R 1 12.2 et R 1 12 A du Code de la construction et de l'habitation réglemente la protection du bâti contre leur infestation par les termites.The decree of June 27, 2006 relating to the application of articles R 1 12.2 and R 1 12 A of the Code of the construction and the housing regulates the protection of the building against their infestation by termites.
Ce décret définit les types de méthodes qui peuvent être uti- lises pour la protection du bâti, soit par une barrière physique, physicochimique ou de contrôle.This decree defines the types of methods that can be used for the protection of the building, either by a physical, physicochemical or control barrier.
Ce décret rend non conforme le traitement du sol par pulvérisation d'insecticide.This decree makes non-compliant treatment of the soil by insecticide spraying.
La présente invention a pour objectif de permettre une pro- tection efficace contre les termites dans le respect de cette nouvelle réglementation.The present invention aims to provide effective protection against termites in accordance with this new regulation.
A cet effet, il a déjà été proposé d'appliquer sur une surface à traiter une composition à base de polyuréthanes renfermant un agent insecticide. II est connu que les polyuréthanes sont obtenus par condensation de polyisocyanates avec des polyols.For this purpose, it has already been proposed to apply to a surface to be treated a polyurethane-based composition containing an insecticidal agent. It is known that polyurethanes are obtained by condensation of polyisocyanates with polyols.
Une telle application d'une composition à base de polyuréthanes n'est toutefois pas de nature à donner satisfaction compte tenu du coût des polyuréthanes, et surtout du caractère corrosif et nocif, voire toxique des polyisocyanates dont la mise en oeuvre nécessite un équipement individuel de protection spécifique et en particulier un masque de protection.Such an application of a composition based on polyurethanes is however not likely to be satisfactory given the cost of polyurethanes, and especially the corrosive and harmful, even toxic polyisocyanates whose implementation requires an individual equipment of specific protection and in particular a protective mask.
La présente invention a pour objet de remédier à cet inconvénient. A cet effet, elle propose un procédé pour la protection contre les insectes, notamment les termites des surfaces à bâtir caractérisé en ce que l'on pulvérise sur la surface à traiter une composition polymérisable constituée par une dispersion ou une émulsion aqueuse d'un liant filmo-
gène renfermant un agent insecticide et susceptible de durcir par évapora- tion d'eau en moins de 12 heures de façon à obtenir un film de protection uniforme continu à la partie interne duquel l'agent insecticide se trouve encapsulé. II est à noter que dans le cadre de l'invention, l'expression composition polymérisable doit être comprise dans un sens très large et désigne en fait toute composition de nature à former sur le sol, après application et séchage, un film continu qui s'étend sur toute la surface à construire, permettant le passage des gaines et des canalisations. Ce film épouse parfaitement les contours du bâti et forme ainsi une barrière physico-chimique empêchant la pénétration des insectes, notamment des termites dans l'ensemble de la surface protégée par la présence de l'insecticide qui est encapsulé à la partie interne du film.The present invention aims to overcome this disadvantage. For this purpose, it proposes a method for protection against insects, in particular termites of building surfaces, characterized in that a polymerizable composition consisting of a dispersion or an aqueous emulsion of a binder is sprayed onto the surface to be treated. film forming An insecticide-containing gene capable of curing by evaporation of water in less than 12 hours so as to obtain a continuous uniform protective film at the inner part of which the insecticidal agent is encapsulated. It should be noted that in the context of the invention, the term "polymerizable composition" must be understood in a very broad sense and in fact means any composition that is capable of forming on the soil, after application and drying, a continuous film which is extends over the entire surface to be built, allowing the passage of ducts and pipes. This film perfectly matches the contours of the frame and thus forms a physico-chemical barrier preventing the penetration of insects, including termites throughout the protected area by the presence of the insecticide which is encapsulated in the inner part of the film.
Selon l'invention, le liant filmogène est choisi dans le groupe formé par les polymères ou copolymères acryliques, styrène-acryliques, ou vinyliques, ainsi que par les latex naturels, les siloxanes, les dispersions ou émulsions de cires naturelles ou synthétiques et les dispersions ou émulsions de polyoléfines et leurs mélanges.According to the invention, the film-forming binder is chosen from the group formed by acrylic, styrene-acrylic or vinyl polymers or copolymers, as well as by natural latices, siloxanes, dispersions or emulsions of natural or synthetic waxes and dispersions. or polyolefin emulsions and mixtures thereof.
Le procédé conforme à l'invention permet donc de recouvrir avant construction du bâti la surface à traiter d'un revêtement formant un film continu après séchage.The method according to the invention therefore allows to cover before construction of the frame the surface to be treated with a coating forming a continuous film after drying.
Ce revêtement peut avantageusement être appliqué par pulvérisation à l'aide d'un pistolet pneumatique classique, ou d'un pistolet haute pression de type Airless®, ou encore d'un pistolet moyenne pression de type Airmix®.This coating may advantageously be applied by spraying using a conventional pneumatic gun, or a high-pressure airless® type gun, or a medium-pressure spray gun type Airmix®.
Selon l'invention, on applique au moins 50 ml, en règle générale de l'ordre de 50 ml à 500 ml de composition polymérisable par mètre carré de surface à traiter.According to the invention, at least 50 ml are applied, as a rule of the order of 50 ml to 500 ml of polymerizable composition per square meter of surface to be treated.
A l'application, cette composition s'étale de manière homo- gène sur la surface à protéger et forme après séchage un film uniforme dont l'épaisseur est en règle générale de l'ordre de 250 μm.On application, this composition spreads homogeneously over the surface to be protected and forms, after drying, a uniform film whose thickness is generally of the order of 250 μm.
Un tel film présente l'avantage de ne pas pénétrer dans un support tel que sable ou remblais après pulvérisation.Such a film has the advantage of not penetrating into a support such as sand or embankment after spraying.
Il peut être appliqué non seulement sur des surfaces essen- tiellement horizontales mais également sur des surfaces verticales ou fortement inclinées (parpaings, panneaux de coffrage, parois externes de canalisations, enduits bitumineux, membranes d'étanchéité, ...) de façon à
former une barrière de protection physico-chimique continue et durable de nature à satisfaire à la législation.It can be applied not only on essentially horizontal surfaces but also on vertical or steeply inclined surfaces (concrete blocks, shuttering panels, external pipe walls, bituminous coatings, waterproof membranes, etc.) so as to to form a continuous and durable physicochemical protective barrier of a nature to satisfy the legislation.
Les insecticides ajoutés à la composition polymérisable sont variables et concernent l'ensemble des molécules appartenant à la classe pt 18 de la directive biocide.The insecticides added to the polymerizable composition are variable and concern all the molecules belonging to class pt 18 of the biocidal directive.
On peut notamment avoir recours à des insecticides suivants : la bifenthrine, le chlorfénapyr, le fipronil ou à la permethrine.The following insecticides may be used: bifenthrin, chlorfenapyr, fipronil or permethrin.
A titre d'exemple, on peut ajouter à la composition polymérisable de 0, 10 à 1 ,00 % en poids de bifenthrine. Selon une autre caractéristique de l'invention, la composition polymérisable renferme des charges minérales et/ ou des pigments.By way of example, from 0 to 10% by weight of bifenthrin can be added to the polymerizable composition. According to another characteristic of the invention, the polymerizable composition contains mineral fillers and / or pigments.
Ces composants ont pour fonction de colorer la composition polymérisable et donc de mieux maîtriser son application sur la surface à traiter. De plus, la charge minérale permet d'abaisser notablement le coût de cette composition, et également de faciliter et d'améliorer son séchage après application.These components serve to color the polymerizable composition and thus to better control its application on the surface to be treated. In addition, the mineral filler makes it possible to significantly lower the cost of this composition, and also to facilitate and improve its drying after application.
Les charges minérales ainsi ajoutées à la composition polymérisable peuvent avantageusement être choisies dans le groupe consti- tué par le carbonate de calcium, la dolomie, le talc, le mica, le sulfate de baryum, l'hydrate d'alumine, le lithopone, le sulfure de zinc, et la silice et leurs mélanges.The mineral fillers thus added to the polymerizable composition may advantageously be chosen from the group consisting of calcium carbonate, dolomite, talc, mica, barium sulfate, alumina hydrate, lithopone, zinc sulphide, and silica and mixtures thereof.
Il s'agit là de charges minérales courantes facilement disponibles dans le commerce. De telles charges minérales peuvent avantageusement avoir une granulométrie comprise entre 0, 1 et 100 μm, de préférence entre 5 et 50 μm.These are common mineral fillers readily available commercially. Such mineral fillers may advantageously have a particle size of between 0.1 and 100 μm, preferably between 5 and 50 μm.
Selon une autre caractéristique de l'invention, la composition polymérisable renferme des additifs de conformation de préférence choisis dans le groupe constitué par les agents dispersants, les agents antimousse, les agents épaississants, les agents coalescents et leurs mélanges.According to another characteristic of the invention, the polymerizable composition contains conformational additives preferably selected from the group consisting of dispersing agents, antifoaming agents, thickening agents, coalescing agents and mixtures thereof.
Ces additifs de conformation ont pour fonction de permettre d'adapter la composition polymérisable de façon à permettre d'obtenir un revêtement qui s'étale de manière homogène sur la surface à protéger à l'application et forme un film fin uniforme après séchage.
Selon une caractéristique particulièrement avantageuse de l'invention, la composition polymérisable renferme en proportion pondérale 10 à 50 %, de préférence 30 à 40 % de liant filmogène.These conformation additives have the function of making it possible to adapt the polymerizable composition so as to make it possible to obtain a coating which spreads homogeneously over the surface to be protected on application and forms a uniform thin film after drying. According to a particularly advantageous characteristic of the invention, the polymerizable composition contains, in weight proportion, 10 to 50%, preferably 30 to 40% of film-forming binder.
Selon une autre caractéristique particulièrement avanta- geuse de l'invention, la composition polymérisable renferme en proportion pondérale :According to another particularly advantageous characteristic of the invention, the polymerizable composition contains, in a proportion by weight:
- de 0 à 70 % de charges minérales,from 0 to 70% of mineral fillers,
- de 0 à 1 % d'agents dispersants,from 0 to 1% of dispersing agents,
- de 0 à 1 % d'agents antimousse, - de 0 à 5 % d'agents de coalescence,from 0 to 1% of anti-foam agents, from 0 to 5% of coalescence agents,
- de 0,2 à 5 % d'agents épaississants, etfrom 0.2 to 5% of thickening agents, and
- de 0 à 0,5 % d'agents mouillants.from 0 to 0.5% of wetting agents.
Pour que le procédé conforme à l'invention puisse donner entière satisfaction, il est nécessaire qu'après son application, la composi- tion polymérisable sèche en moins de 12 heures pour permettre d'intervenir sur le chantier dès le lendemain de cette application, en particulier pour couler une dalle de béton.In order for the process according to the invention to be completely satisfactory, it is necessary that after its application, the polymerizable composition dries in less than 12 hours in order to enable work to be carried out on the site the day after this application. particular for pouring a concrete slab.
Or, un tel impératif peut parfois poser des problèmes par temps froid ou en présence d'une humidité élevée. Pour remédier à cet inconvénient, il est proposé, selon une autre caractéristique de l'invention, d'ajouter à une telle composition polymérisable un agent activateur de prise, notamment constitué par un liant hydraulique, de préférence dispersé dans un solvant organique.However, such a requirement can sometimes cause problems in cold weather or in the presence of high humidity. To remedy this drawback, it is proposed, according to another characteristic of the invention, to add to such a polymerizable composition a setting activating agent, in particular consisting of a hydraulic binder, preferably dispersed in an organic solvent.
Ce liant hydraulique peut à titre d'exemple être constitué par du ciment Portland, un aluminate de calcium ou un sulfate de calcium éventuellement associé à des additifs connus de nature à ajuster les temps de prise, en les retardant ou en les accélérant tel qu'à titre d'exemple carbonate de lithium et/ ou bicarbonate de sodium.This hydraulic binder can for example be constituted by Portland cement, a calcium aluminate or a calcium sulfate optionally combined with known additives such as to adjust setting times, by delaying or accelerating them, such as as an example lithium carbonate and / or sodium bicarbonate.
Selon l'invention, on ajoute de préférence à la composition polymérisable 30 à 70 % en poids d'agent activateur de prise.According to the invention, 30 to 70% by weight of setting activating agent is preferably added to the polymerizable composition.
L'invention concerne également un film de protection anti insectes, notamment antitermites obtenu par la mise en oeuvre du procédé susmentionné.The invention also relates to an insect protection film, particularly antitermites obtained by the implementation of the aforementioned method.
Ce film de protection est caractérisé en ce qu'il est constitué par un film uniforme continu à la partie interne duquel un agent insecticide est encapsulé.This protective film is characterized in that it consists of a continuous uniform film at the inner part of which an insecticidal agent is encapsulated.
Il est à noter qu'un tel film peut également faire office de film hydrofuge permettant d'éviter les remontées d'humidité.
Les caractéristiques du procédé et du film de protection qui font l'objet de l'invention seront décrites plus en détail en se référant aux exemples ci-dessous de compositions polymérisables pouvant être appliquées par le procédé conforme à l'invention.It should be noted that such a film can also act as a water repellent film to prevent rising damp.
