Description

COMPOSITION DE NETTOYAGE CLEANING COMPOSITION
La présente invention porte sur une composition de nettoyage utilisable notamment pour enlever à température ambiante des mastics polysulfures, des goudrons, des fuels et autres salissures grasses ou adhérentes de surfaces dures métalliques, de céramiques, de verre, de matières plastiques, de circuits imprimés ou de textiles.The present invention relates to a cleaning composition which can be used in particular for removing at room temperature polysulphide sealants, tars, fuels and other greasy or adherent soiling from hard metallic surfaces, ceramics, glass, plastics, printed circuits or of textiles.
Traditionnellement, ces surfaces étaient nettoyées au moyen de solvants chlorés tels que le chlorure de méthylène, le 1 ,1 ,1-trichloroéthane ou le 1 ,1 ,2-trichloro-1 ,2,2-trifluoroéthane mais ces solvants ont été condamnés par le protocole de Montréal en raison de leur impact sur la couche d'ozone ou en raison de leur toxicité.Traditionally, these surfaces were cleaned using chlorinated solvents such as methylene chloride, 1, 1, 1-trichloroethane or 1, 1, 2-trichloro-1, 2,2-trifluoroethane but these solvents were condemned by the Montreal Protocol because of their impact on the ozone layer or because of their toxicity.
Pour remplacer ces solvants chlorés, il a été utilisé des esters tels que les lactates d'alkyle. Ces produits présentent l'inconvénient d'être malodorants et corrodent les surfaces à nettoyer. Pour enlever des mastics polysulfures (Thiokol) de surfaces en verre ou métalliques, il est proposé dans le brevet US 5,561 ,215 une composition comprenant au moins 50 % en poids de pyrrolidones et tout particulièrement de N-méthyl-2-pyrrolidone.To replace these chlorinated solvents, esters such as alkyl lactates have been used. These products have the disadvantage of being smelly and corrode the surfaces to be cleaned. To remove polysulphide sealants (Thiokol) from glass or metallic surfaces, US Pat. No. 5,561,215 proposes a composition comprising at least 50% by weight of pyrrolidones and very particularly of N-methyl-2-pyrrolidone.
Ces solvants pyrrolidoniques présentent l'inconvénient d'être hygroscopiques, ce qui est rédhibitoire lorsque les durées de nettoyage sont élevées, car la présence d'eau entraîne une baisse d'efficacité desdits solvants. Ils sont également malodorants.These pyrrolidonic solvents have the drawback of being hygroscopic, which is unacceptable when the cleaning times are high, since the presence of water results in a reduction in the efficiency of said solvents. They are also smelly.
En outre, ces solvants pyrrolidoniques seraient suspectés d'être cancérigènes.In addition, these pyrrolidonic solvents are suspected of being carcinogenic.
Egalement, les compositions à base de solvants pyrrolidoniques ont un effet décapant et, par conséquent leur utilisation est rédhibitoire dans certains types d'applications de la présente invention car ils attaquent le revêtement en peinture.Also, the compositions based on pyrrolidonic solvents have a pickling effect and therefore their use is prohibitive in certain types of applications of the present invention because they attack the paint coating.
La demanderesse a maintenant trouvé une composition de nettoyage polyvalente constituée de solvants ne présentant pas les inconvénients précédemment décrits et permettant d'enlever efficacement à température ambiante des mastics polysulfures, des goudrons, des fuels et autres salissures grasses ou adhérentes de surfaces dures métalliques, de céramiques, de verre, de matières plastiques, de circuits imprimés ou de textiles. La présente invention a donc pour objet une composition de nettoyage caractérisée en ce qu'elle comprend de :The Applicant has now found a versatile cleaning composition made up of solvents which do not have the drawbacks described above and which make it possible to effectively remove at room temperature polysulphide sealants, tars, fuels and other greasy or adherent dirt from hard metal surfaces, ceramics, glass, plastics, printed circuits or textiles.
