Description
Barrière anti termites, anti attaque chimique, anti rayonnement beta et alpha, anti diffusion de gaz La présente invention concerne le traitement de finition d'une résine d'étanchéité, de revêtement de sol ou de protection anti corrosion. Cette résine peut être appliquée sur un support béton, métallique, bois, isolant, matériau composite pour assurer une protection du support (étanchéité, anti corrosion, pare vapeur, revêtement de sol). La finition est destinée à apporter à la résine diverses propriétés recherchées et souhaitées telles que : barrière contre l'agression des termites ou insectes pour protéger le bois, protection de la résine contre l'agression de produits chimiques très agressifs, protection de la résine contre le rayonnement Béta et Alpha dans les centrales nucléaires, protection contre la diffusion de gaz. La technique de finition présentée dans l'invention permettant d'obtenir les fonctions de protection recherchées consiste à coller sur la résine encore fraîche un tissu de verre dont les fils sont très fins et parfaitement liés, sans vide entre les fils comme c'est le cas des tissus de verre stratifil par exemple. Un tel tissu est étanche à l'eau qui ne peut s'écouler entre les fils. Un tissu de cette performance peut être obtenu par exemple par assemblage de fils comportant 300 filaments de 511 de diamètre à raison de 48 fils dans le sens chaine et 21 fils dans le sens trame. On obtient ainsi un composite composé d'une résine et d'une membrane de verre adhérente à la résine. Cette membrane est donc directement apparente, et non incluse à l'intérieur de la résine, comme c'est généralement le cas pour des matériaux composites.The present invention relates to the finishing treatment of a sealing resin, flooring or anti-corrosion protection. This resin can be applied on a concrete, metal, wood, insulating or composite material substrate to protect the substrate (waterproofing, anti-corrosion, vapor barrier, floor covering). The finish is intended to provide the resin with various desired and desired properties such as: barrier against the aggression of termites or insects to protect the wood, protection of the resin against the aggression of very aggressive chemicals, protection of the resin against Beta and Alpha radiation in nuclear power plants, protection against gas diffusion. The finishing technique presented in the invention making it possible to obtain the desired protective functions consists in bonding to the still-fresh resin a glass fabric whose threads are very fine and perfectly bonded, with no void between the threads as it is the for example, ribbed glass fabrics. Such a fabric is waterproof which can not flow between the threads. A fabric of this performance can be obtained, for example, by assembling yarns comprising 300 filaments 511 in diameter with 48 threads in the warp direction and 21 threads in the weft direction. A composite of a resin and a glass membrane adhered to the resin is thus obtained. This membrane is therefore directly apparent, and not included inside the resin, as is generally the case for composite materials.
Les résines pouvant être utilisées pour ce type d'application sont de type polyuréthane, polyurée, polyurée-uréthane, époxy, acrylique, méthacrylate, polyester, vinyle, vinyl ester. Cette technique permet d'envisager les applications suivantes : 1. protection de la résine, et donc du support sur laquelle la résine est appliquée, contre l'attaque des termites ou insectes : en effet, les termites n'attaquent pas le verre, et un test de laboratoire au centre technique du bois a confirmé l'efficacité de la barrière face à l'agression des termites. Pour protéger le bois contre l'agression des termites, il existe deux principes : . traitement du bois avec des produits chimiques toxiques pour les termites . protection du bois par des membranes traitées avec des produits toxiques pour les termites, ou mise en place d'une barrière physique empêchant les termites d'atteindre le bois. Ce type de protection est celui décrit dans la présente invention. Les techniques existantes utilisent des tissus de mailles de fils inox très fin ne créant aucun passage entre les fils( exemple : système TERMIMESH). Ce système a l'inconvénient d'être lotird, difficile de mise en place, ne peut être découpé facilernetit, n'est pas adhérent au support et est difficile à mettre en plaee. Une fixation mécanique est nécessaire, et cette fixation peut dégrader le support. La toile étant en outre indépendante, et non adhérente, le risque de passage de termites existe. Des essais de barrière anti termites ont été effectués en incorporant dans la résine des tissus de verre, type stratifil, matériaux couramment utilisé dans les matériaux composites. Les essais n'ont pas été concluants, parce que les termites, en rongeant la résine, trouvaient le tissu de verre et arrivaient à passer entre les mailles du tissu pour ensuite attaquer le bois. Des barrières anti termites sont également proposées en créant une barrière constituée de verre pilé coulé le long de dalles béton à protéger pour éviter la migration des termites du sol vers la dalle ( système TERMIGLASS). Cette technique ne peut être utilisée pour protéger les structures bois elle mêmes. La présente invention utilise un tissu de verre à fils très fins et très serrés tissés, ne permettant aucun passage libre entre les fils. Ces tissus sont même étanches à l'eau, l'eau déposée sur le tissu ne passant pas à travers les mailles. La membrane de verre est en outre très mince, et très facile à découper pour suivre la géométrie du support. La membrane est en outre parfaitement adhérente au support à protéger, garantissant ainsi son efficacité. 2. Protection contre les attaques chimiques de la résine, qui elle - même protège le support (béton ou acier) : Certaines résines sont utilisées pour assurer la protection anti - corrosion de supports béton - par exemple rétentions chimiques. Lorsque les agents chimiques sont fortement agressifs - H2SO4 concentré, HNO3 concentré par exemple etc... ces résines sont dégradées par les attaques chimiques, et ne peuvent assurer la protection espérée du béton. L'application de la membrane de verre sur la résine assure une protection de la résine face aux agents chimiques, qui sont blo- qués par la membrane étanche et rie pettvetit diffuser dans la résine. Ainsi tous les produits chirriletties auxquels le verre est résistant peuvent ainsi être bloqués par la membrane de verre, évitant ainsi l'attaque chimique du support. Certaines résines (vinyl ester par exeniple) utilisent en outre des écailles de verre pour améliorer la résistance chimique, les liquides corrosifs devant diffuser sur un chemin plus long en évitant les écailles de verre. Intercaler dans la résine une membrane de verre étanche améliore sensiblement la résistance à la corrosion du système, les agents chimiques agressifs étant bloqués dans leur diffusion par la membrane de verre.The resins that can be used for this type of application are polyurethane, polyurea, polyurea-urethane, epoxy, acrylic, methacrylate, polyester, vinyl, vinyl ester. This technique makes it possible to envisage the following applications: 1. protection of the resin, and therefore of the support on which the resin is applied, against the attack of termites or insects: indeed, termites do not attack glass, and a laboratory test at the Wood Technology Center confirmed the effectiveness of the barrier against termite aggression. To protect wood against aggression of termites, there are two principles:. treatment of wood with toxic chemicals for termites. protection of the wood with membranes treated with toxic products for termites, or establishment of a physical barrier preventing termites from reaching the wood. This type of protection is that described in the present invention. Existing techniques use very fine stainless steel mesh fabrics that do not create any passage between the wires (example: TERMIMESH system). This system has the disadvantage of being lotird, difficult to set up, can not be cut out easy, is not adherent to the support and is difficult to implement. A mechanical fixation is necessary, and this fixation can degrade the support. The fabric is also independent, and not adherent, the risk of termite passage exists. Termite barrier tests have been carried out by incorporating in the resin glass fabrics, roving type, materials commonly used in composite materials. The tests were inconclusive because the termites, by gnawing the resin, found the glass cloth and could pass between the mesh of the fabric and then attack the wood. Anti-termite barriers are also proposed by creating a barrier consisting of crushed glass cast along concrete slabs to protect against the migration of termites from the soil to the slab (TERMIGLASS system). This technique can not be used to protect the wood structures themselves. The present invention uses a glass fabric with very fine and very tight woven threads, allowing no free passage between the threads. These fabrics are even waterproof, the water deposited on the fabric does not pass through the mesh. The glass membrane is also very thin, and very easy to cut to follow the geometry of the support. The membrane is also perfectly adherent to the support to be protected, thus guaranteeing its effectiveness. 2. Protection against chemical attacks of the resin, which itself protects the support (concrete or steel): Some resins are used to ensure the anti-corrosion protection of concrete supports - for example chemical retentions. When the chemical agents are highly aggressive - concentrated H2SO4, concentrated HNO3 for example etc ... these resins are degraded by chemical attacks, and can not provide the expected protection of concrete. Application of the glass membrane to the resin provides protection of the resin against chemicals, which are blocked by the waterproof membrane and allow it to diffuse into the resin. Thus, all the chirrylate products to which the glass is resistant can thus be blocked by the glass membrane, thus avoiding the chemical attack of the support. Some resins (vinyl ester for example) also use glass flakes to improve the chemical resistance, corrosive liquids to diffuse on a longer path avoiding glass scales. Interposing a waterproof glass membrane in the resin substantially improves the corrosion resistance of the system, the aggressive chemical agents being blocked in their diffusion by the glass membrane.
La membrane de verre peut ainsi être placée de manière apparente en finition sur la résine, ou intercalée en sandwich à l'intérieur de la résine. 3. protection contre la diffusion des rayonnements alpha ou béta émis dans les centrales nucléaires. Les rayonnements alpha sont complétement arrêtés par la membrane. La diffusion du rayonnement béta est considérablement ralentie, et son énergie initiale réduite, ce qui permet d'éviter la dégradation de la résine qui sert de support à la membrane de verre. Dans les réacteurs EPR, en cas d'accident, un rayonnement très intense de rayonnement béta dégrade complètement les résines de protection du bâtiment réacteur qui se transforment en poudre, créant ainsi un problème grave de sécurité du bâtiment réacteur. L'amortissement de l'énergie des rayonnements béta éviterait cette dégradation. 4. protection contre la diffusion des gaz : certains gaz doivent être confinés dans un local, et ne pas diffuser à l'extérieur du local. Ainsi dans l'industrie nucléaire les gaz suivants doivent être confinés : Tritium, Hydrogène, Radon etc .... Une membrane de verre réduit sensiblement la diffusion de ces gaz.35The glass membrane can thus be placed apparently in finish on the resin, or inserted sandwiched inside the resin. 3. protection against the diffusion of alpha or beta radiation emitted in nuclear power plants. Alpha radiation is completely stopped by the membrane. The diffusion of the beta radiation is considerably slowed down, and its initial energy is reduced, which makes it possible to avoid the degradation of the resin which serves as a support for the glass membrane. In EPR reactors, in the event of an accident, a very intense radiation of beta radiation completely degrades the protective resins of the reactor building which turn into powder, thus creating a serious problem of reactor building safety. The energy damping of beta radiation would avoid this degradation. 4. protection against the diffusion of gases: certain gases must be confined in a room, and not to diffuse outside the room. Thus in the nuclear industry the following gases must be confined: Tritium, Hydrogen, Radon, etc. A glass membrane substantially reduces the diffusion of these gases.
