PRODUIT ET PROCEDE POUR LIBERER PAR COMBUSTION DANS
L'ATMOSPHERE UNE SUBSTANCE ACTIVE TELLE QU'UN INSECTICIDE
La présente concerne un produit et un procédé pour libérer de façon continue un principe actif insecticide ou antiparasite dans l'atmosphère, notamment sous l'effet de la chaleur dégagée par la combustion lente et régulière d'un élément porteur de ce principe actif.PRODUCT AND METHOD FOR COMBUSTION RELEASE INTO
THE ATMOSPHERE AN ACTIVE SUBSTANCE SUCH AS AN INSECTICIDE
The present invention relates to a product and a method for continuously releasing an insecticidal or antiparasitic active principle into the atmosphere, in particular under the effect of the heat given off by the slow and regular combustion of an element carrying this active principle.
I1 existe diverses façons de mettre en oeuvre des substances anti-parasites ou insecticides notamment à usage domestique. L'une d'elles consiste à utiliser un élément porteur constitué d'une mélange de sciure de bois à granulométrie très fine, d'un liant tel que l'amidon et d'un comburant tel qu'un nitrate. A cet élément porteur sont incorporées les matières actives insecticides, puis on applique le mélange sous forme de nappe, de couche, de plaque ou de bande. I1 reste ensuite à mettre le produit en forme pour son utilisation. Une technique très courante consiste à emboutir la plaque pour y prédécouper une double spirale. There are various ways of using anti-parasite or insecticide substances, in particular for domestic use. One of them consists in using a carrier element made up of a mixture of very fine particle size sawdust, a binder such as starch and an oxidizer such as a nitrate. Insecticidal active ingredients are incorporated into this carrier element, then the mixture is applied in the form of a sheet, layer, plate or strip. I1 then remains to shape the product for its use. A very common technique is to stamp the plate to pre-cut a double spiral.
Chacune des spirales ainsi obtenues, peut être alors fixée horizontalement sur un support. I1 suffit ensuite avec une allumette de faire démarrer la combustion en enflammant une des extrémités de la spirale. La combustion s'entretient d'elle-même, et la chaleur dégagée par la partie qui brûle, contribue à libérer l'insecticide dans la partie immédiatement adjacente qui n'a pas encore brûlé. Each of the spirals thus obtained can then be fixed horizontally on a support. I1 then suffices with a match to start the combustion by igniting one of the ends of the spiral. The combustion maintains itself, and the heat given off by the burning part contributes to releasing the insecticide in the immediately adjacent part which has not yet burned.
Cette technique simple, présente cependant quelques inconvénients. Tout d'abord, la nature du mélange et notamment la sciure de bois fait que le produit conditionné est fragile et l'utilisateur, lorsqu'il sépare les spirales l'une de l'autre, les brise fréquemment, ce qui compromet l'utilisation subséquente du produit. Cette fragilité est également une cause d'incident pendant la combustion du produit alors qu'il est fixé sur son support. En outre, la sciure de bois est un matériau de constitution variable dont la combustion est irrégulière et incomplète, et susceptible de produire quand elle brûle des fumées indésirables. This simple technique, however, has some drawbacks. First of all, the nature of the mixture and in particular the sawdust makes the conditioned product fragile and the user, when he separates the spirals from one another, breaks them frequently, which compromises the subsequent use of the product. This fragility is also a cause of incident during the combustion of the product while it is fixed on its support. In addition, sawdust is a material of variable constitution whose combustion is irregular and incomplete, and likely to produce when it burns unwanted fumes.
La présente invention a pour objet de remédier à ces inconvénients en préconisant pour former le produit porteur, l'utilisation de matériaux plus appropriés. The object of the present invention is to remedy these drawbacks by recommending the use of more suitable materials to form the carrier product.
Le produit selon l'invention est constitué d'un élément porteur tel qu'une plaque dans laquelle sont prédécoupées des formes, par exemple spiralées, une substance active étant imprégnée dans cet élément porteur et il est caractérisé en ce que l'élément porteur est réalisé à partir d'une matière cellulosique artificielle telle que le carton. The product according to the invention consists of a carrier element such as a plate in which shapes, for example spiral shapes are precut, an active substance being impregnated in this carrier element and it is characterized in that the carrier element is made from an artificial cellulosic material such as cardboard.
Le produit comprend également un comburant qui peut être un nitrate, un nitrite ou de la nitrocellulose. The product also includes an oxidizer which can be a nitrate, a nitrite or a nitrocellulose.
La caractéristique du produit selon l'invention, à savoir le remplacement d'un mélange de sciure de bois très fine et d'un liant par cette matière artificielle, présente les avantages suivants. Le celloderme ou le carton sont des matériaux qu'il est facile de se procurer avec toutes les spécifications souhaitables quant à l'épaisseur, les caractéristiques mécaniques, la couleur etc. La fabrication de ces matériaux est bien suivie et obéit à des normes, ce qui garantit la reproductibilité des caractéristiques et des propriétés. En outre, selon les spécifications choisies, on peut obtenir un matériau qui présentera les caractéristiques et une épaisseur telles que l'inconvénient de fragilité mentionné ci-dessus sera pratiquement éliminé dans des conditions normales d'utilisation. La matière cellulosique artificielle est de préférence le carton et avantageusement un carton fort ou "celloderme" disponible sous forme de feuille de 1 à 5 mm d'épaisseur et formée à partir de pâte à papier ou de papier recyclé. The characteristic of the product according to the invention, namely the replacement of a mixture of very fine sawdust and a binder by this artificial material, has the following advantages. Celloderm or cardboard are readily available materials with all desirable specifications for thickness, mechanical properties, color, etc. The manufacturing of these materials is well monitored and obeys standards, which guarantees the reproducibility of characteristics and properties. In addition, according to the specifications chosen, it is possible to obtain a material which will have the characteristics and a thickness such that the disadvantage of brittleness mentioned above will be practically eliminated under normal conditions of use. The artificial cellulosic material is preferably cardboard and advantageously a strong cardboard or "celloderm" available in the form of a sheet 1 to 5 mm thick and formed from pulp or recycled paper.
Le produit de l'invention peut être préparé selon le mode opératoire suivant qui est donné à titre d'exemple. The product of the invention can be prepared according to the following procedure which is given by way of example.
On prend une plaque de celloderme P 20/10 fournie par la Société Cartonnerie Jean SA de dimensions 90/150 cm et d'épaisseur 2 mm. On fait tremper cette plaque dans une solution aqueuse de nitrate de potassium à 10 % en masse. We take a P 20/10 celloderm plate supplied by the company Cartonnerie Jean SA with dimensions 90/150 cm and thickness 2 mm. This plate is soaked in an aqueous solution of potassium nitrate at 10% by mass.
La trempe est effectuée à une température de 300C environ.The quenching is carried out at a temperature of approximately 300C.
On égoutte puis on rince à l'eau pendant 5 à 10 secondes et on sèche dans un courant d'air tiède à 400C environ. On imprègne ensuite la plaque avec une solution alcoolique de 8 % en masse d'insecticide de type alléthrine, on sèche à 300C. It is drained and then rinsed with water for 5 to 10 seconds and dried in a stream of warm air at around 400C. The plate is then impregnated with an alcoholic solution of 8% by mass of insecticide of allethrin type, dried at 300C.
Le produit résultant est découpé sous forme de plaques de forme carrée de 15 cm de côté. Dans ces plaques, on forme à l'aide d'un emporte pièce une prédécoupe spiralée permettant d'obtenir deux spirales emboîtées de 6 mm de largeur chacune. L'épaisseur qui est celle du celloderme initial est de 2 mm. The resulting product is cut into the form of square plates 15 cm square. In these plates, a spiral precut is formed using a cookie cutter allowing two interlocking spirals of 6 mm in width to be obtained. The thickness which is that of the initial celloderm is 2 mm.
Une spirale, ou serpentin, peut être extraite de cette plaque prédécoupée sans rupture, même en ne prenant pas de précaution particulière de manipulation et sans former de poussière ou de débris. A spiral, or serpentine, can be extracted from this precut plate without breaking, even without taking any special handling precautions and without forming dust or debris.
Fixée horizontalement sur son support et allumée, elle se consume de manière régulière et continue à une vitesse de 20 cm/heure environ, sans mettre de fumées acres ou désagréables. Fixed horizontally on its support and lit, it burns regularly and continuously at a speed of about 20 cm / hour, without putting on acrid or unpleasant fumes.
Divers insecticides ou anti-parasites peuvent être utilisés selon la nature des insectes ou des parasites à traiter, par exemple, alléthrine, esbiothrine, pyrèthre, ciperméthrine, butoxycarboxime. D'une façon générale, les substances insecticides utilisées dans les émanateurs électriques conviennent très bien pour l'application visée par la présente invention. Various insecticides or anti-parasites can be used depending on the nature of the insects or parasites to be treated, for example, allethrin, esbiothrin, pyrethrum, cipermethrin, butoxycarboxime. In general, the insecticidal substances used in electric emitters are very suitable for the application targeted by the present invention.
On peut incorporer diverses charges pour autant qu'elles n'interfèrent pas avec l'utilisation et en particulier qu'elle ne gènent pas la combustion lente et régulière du produit. Various fillers can be incorporated, provided that they do not interfere with use and in particular that they do not interfere with the slow and regular combustion of the product.
Ces charges peuvent être des colorants ou des pigments, des substances odoriférantes, des agents renforçateurs, des substances améliorant la résistance à la pénétration de l'humidité, etc. These fillers can be dyes or pigments, odoriferous substances, reinforcing agents, substances improving resistance to the penetration of moisture, etc.
Les techniques pour incorporer les constituants dans le carton sont bien connues. On peut procéder par pulvérisation ou aspersion ou par imprégnation en égouttant ou en exprimant l'excès de solution, par exemple en faisant passer la plaque entre les rouleaux presseurs. Le séchage est une étape importante dans la mesure où il faut éviter des concentrations ou des cristallisations de substance notamment à la surface du produit. Les vitesses de séchage optimales sont comprises entre 5 et 60 minutes environ, pour une température comprise entre 30 et 600C et avantageusement entre 40 et 500C. Les différentes étapes du procédé peuvent être effectuées dans un ordre variable. Si les solvants utilisés le permettent, il est possible d'imprégner simultanément le carton avec le comburant et l'insecticide. The techniques for incorporating the components into the carton are well known. One can proceed by spraying or sprinkling or by impregnation by draining or expressing the excess solution, for example by passing the plate between the pressure rollers. Drying is an important step since it is necessary to avoid concentrations or crystallizations of the substance, in particular on the surface of the product. The optimal drying rates are between 5 and 60 minutes approximately, for a temperature between 30 and 600C and advantageously between 40 and 500C. The different steps of the process can be carried out in a variable order. If the solvents used allow, it is possible to simultaneously impregnate the cardboard with the oxidizer and the insecticide.
