Abstract
Description
La présente invention concerne la composition d'un matériau constitutif d'une barrière physico-chimique qui vient s'interposer entre le sol et les bâtiment ou les éléments d'ouvrage susceptibles d'être franchis par des termites tels, par exemple, que les joints de dilatations, la jonction des murs et des dalles ou des pieux de soutènement, sans que cette liste ne soit limitative. The present invention relates to the composition of a material constituting a physicochemical barrier which is interposed between the ground and the buildings or workpieces likely to be crossed by termites such as, for example, that the expansion joints, the junction of walls and slabs or retaining piles, without this list being exhaustive.
De part le monde, la technique la plus répandue consiste en l'usage de barrières chimiques réalisées par épandage au sol avant érection du bâtiment, de pesticides liquides à raison de 5 litres par mètre carré environ. Plus récemment, des barrières physico-chimiques présentées sous la forme de films de polymères tels que le polyéthylène chargés de pesticides ou sous la forme de résines polymérisables additivées de biocides ont été utilisées. Des barrières physiques composées de fins grillages métalliques sont en usage dans différentes parties du monde ainsi que des écrans de gravier calibré. Worldwide, the most widespread technique consists of the use of chemical barriers made by spreading the soil before erection of the building, liquid pesticides at the rate of 5 liters per square meter. More recently, physicochemical barriers presented in the form of polymer films such as polyethylene loaded with pesticides or in the form of polymerizable resins additives of biocides have been used. Physical barriers made up of thin metal fences are in use in different parts of the world as well as calibrated gravel screens.
L'ensemble de ces procédés présente différents inconvénients : All of these methods have different disadvantages:
Les barrières chimiques sont génératrices de pollution et leur usage est réglementairement restreint. Chemical barriers are generators of pollution and their use is legally restricted.
Les barrières physico-chimiques sous forme de films nécessitent une mise en oeuvre longue et de nombreux raccords. Les barrières physico-chimiques sous forme de résines polymérisables et chargées en insecticides sont susceptibles de générer des pollutions de part la migration du biocide qui n'est pas fixé. The physicochemical barriers in the form of films require a long implementation and many connections. Physico-chemical barriers in the form of polymerizable resins and loaded with insecticides are likely to generate pollution by the migration of the biocide which is not fixed.
Les barrières physiques classiques, utilisant des grillages métalliques par exemple, manquent de souplesse et doivent être finement ajustées aux éléments de maçonnerie pour être efficientes. Cette contrainte entraîne une installation longue et complexe. Conventional physical barriers, using wire mesh for example, lack flexibility and must be finely tuned to the masonry elements to be efficient. This constraint results in a long and complex installation.
La présente invention est une formulation constitutive d'une barrière physico-chimique qui vient s'interposer entre le sol et les éléments d'ouvrage susceptibles d'être franchis par des termites, tels que les joints de dilatations, la jonction des murs et des dalles ou des pieux de soutènement par exemple. La protection de l'ensemble de la surface sous et en périphérie de la dalle et des murs de fondations est également possible grâce à la présente invention. The present invention is a formulation constituting a physicochemical barrier which comes interposed between the ground and the workpieces likely to be crossed by termites, such as expansion joints, the junction of the walls and walls. slabs or retaining piles for example. The protection of the entire surface under and around the slab and the foundation walls is also possible thanks to the present invention.
La formulation objet de l'invention répandue sous forme liquide ou pâteuse grâce à une pompe idoine, se solidifie en quelques heures et forme un film homogène à la surface du sol dégagé avant édification du bâtiment à protéger ou bien sur les éléments de maçonnerie afin de faire obstacle au passage des termites souterrains. The formulation object of the invention spread in liquid or pasty form by means of a suitable pump, solidifies in a few hours and forms a homogeneous film on the surface of the ground cleared before erection of the building to be protected or on the masonry elements in order to hinder the passage of underground termites.
La formulation objet de l'invention est une émulsion de latex synthétique polymérisable à l'air par exemple et incorporant en dispersion des particules, granulés ou fibres de polyoléfines chargées en insecticide. Les insecticides sont incorporés aux polyoléfines selon des techniques connues de l'homme de l'art tel notamment le mélange à chaud par une extrudeuse bi-vis à flux inverses. The formulation forming the subject of the invention is a synthetic latex emulsion polymerizable in air for example and incorporating into dispersion particles, granules or polyolefin fibers loaded with insecticide. The insecticides are incorporated into the polyolefins according to techniques known to those skilled in the art, such as hot mixing by a twin-screw extruder reverse flow.
La substance biocide est fortement fixée dans la matrice par le biais de la liaison mécanique créée entre la résine solidifiée et les particules de polyoléfine dans lesquelles elle a été intégrée. Cette liaison mécanique combine les avantages suivants : • ainsi fixée, la diffusion de la substance biocide dans le milieu est très fortement réduite ; • la cohésion du film formé après solidification du matériau est renforcée, les particules assurant un rôle d'armature. The biocidal material is strongly fixed in the matrix through the mechanical bond created between the solidified resin and the polyolefin particles in which it has been incorporated. This mechanical bond combines the following advantages: • thus fixed, the diffusion of the biocidal substance in the medium is very greatly reduced; The cohesion of the film formed after solidification of the material is reinforced, the particles ensuring a role of reinforcement.
20 Les insecticides convenant dans cet usage et pouvant être associées au polyéthylène basse densité, au polyéthylène haute densité, au polypropylène ou à l'éthyle-vinyle-acétate peuvent être choisis, sans que ces listes ne soient restrictives, parmi : Suitable insecticides suitable for use with low density polyethylene, high density polyethylene, polypropylene or ethyl vinyl acetate can be chosen without these lists being restrictive, among:
