Abstract

The invention relates to the greenery caused by the establishment of plants on materials. To prevent this greenery, the materials are treated with a solution of silicone and fungicidal salt. The invention applies especially to the treatment of roofing products.

Description

L'invention concerne un procédé pour préyenir la formation de verdissement sur un article en matériau poreux non métallique, notamment un élément de couverture de bâtiment. The invention relates to a method for preventing the formation of greening on an article made of non-metallic porous material, in particular a building covering element.

Depuis quelques années, on constate que le verdissement provoqué par la fixation de végétaux tels qu'algues, mousses, lichens, sur tous les matériaux à l'exception des métaux, s'accroît puisqu'il intéresse même quelquefois des toitures déjà anciennes qui n'ont jamais verdi. In recent years, we have noticed that the greening caused by the fixation of plants such as algae, mosses, lichens, on all materials except metals, has increased since it even sometimes involves already old roofs which do not have never greened.

Selon la présente invention, on empêche ou on retarde considérablement ce verdissement en traitant les éléments de couverture, après fabrication avec une solution contenant à la fois des sels fongicides solubilisables par l'eau de pluie et du silicone hydrosoluble. According to the present invention, this greening is considerably prevented or delayed by treating the covering elements, after manufacture with a solution containing both fungicidal salts soluble in rainwater and water-soluble silicone.

Après traitement et séchage suivant le procédé habituellement utilisé pour hydrofuger des produits par simple siliconage, ceux-ci n'absorbent l'eau que très lentement. Par conséquent, les sels d'éléments fongicides, par exemple des sels de certains métaux, sont emprisonnés dans le matériau et leur solubilisation par l'eau de pluie est possible mais tres lente puisque les eaux de pluie ne peuvent pénétrer que faiblement dans les produits et ne peuvent solubiliser que de faibles quantités des sels introduits. Lors de son évaporation, I'eau draîne des cations métalliques en surface où leur présence empêche la fixation des végétaux. After treatment and drying according to the process usually used for water repellency by simple siliconization, these absorb water only very slowly. Consequently, the salts of fungicidal elements, for example salts of certain metals, are trapped in the material and their solubilization by rainwater is possible but very slow since rainwater can only penetrate weakly into the products. and can only dissolve small amounts of the introduced salts. During its evaporation, the water drains metallic cations on the surface where their presence prevents the plants from fixing.

Le procédé présente en outre une particularité spécifique pour la préparation du liquide de traitement. The process also has a specific feature for the preparation of the treatment liquid.

En effet, les sels des éléments fongicides étant insolubles dans la solution de silicone, on procède à un pré-mélange de ces sels avec une base azotée (ammoniaque, sels d'ammonium, amines, amides...) qui, en permettant la formation de complexes aminés (par exemple du type cupriaminé), assure leur maintien en solution en présence de silicone. Indeed, the salts of the fungicidal elements being insoluble in the silicone solution, a premix of these salts is carried out with a nitrogenous base (ammonia, ammonium salts, amines, amides ...) which, by allowing the formation of amino complexes (for example of the cupriamine type), ensures their maintenance in solution in the presence of silicone.

Les sels des éléments fongicides utilisables sont, de préférence, les sels de métaux et, plus particulièrement, les sulfates de zinc et de cuivre. The salts of the fungicidal elements which can be used are preferably the metal salts and, more particularly, the zinc and copper sulphates.

La solution de silicone est de préférence une solution de siliconate de potassium.The silicone solution is preferably a potassium siliconate solution.

De préférence, les teneurs en silicone des solutions de traitement sont comprises entre 0,3 o et 2 % exprimées en volume de solution à partir d'un produit du commerce comprenant environ 50 96 de matières actives.  Preferably, the silicone contents of the treatment solutions are between 0.3% and 2% expressed by volume of solution from a commercial product comprising approximately 50% of active materials.

De préférence, les teneurs en sels d'éléments fongicides sont comprises entre 0,1 et 5 % exprimé en % du poids de la solution définitive. Preferably, the salt contents of fungicidal elements are between 0.1 and 5% expressed as% of the weight of the final solution.

La proportion de solution absorbée par le produit à traiter est comprise entre I et 10 % de son poids. The proportion of solution absorbed by the product to be treated is between I and 10% of its weight.
