Description

La présente invention concerne le nettoyage des rouleaux mouilleurs habillés de textiles, utilisés dans les dispositifs de mouillage conventionnel de machines à imprimer offset. Elle propose de nouvelles compositions utilisables à cet effet.The present invention relates to the cleaning of wet rollers dressed with textiles, used in conventional wetting devices of offset printing machines. It proposes new compositions usable for this purpose.

L'offset est un procéde lithographique reposant sur un équilibre hydrophile-lipophile parfait. L'hydrophilie est fonction de l'état de pro preste des rouleaux mouilleurs. Ceux-ci se chargent en cours d'impression non seulement de salissures grasses, mais aussi de salissures solides (pigments des encres, peluches de papier, charges minérales) rompant ainsi cet équilibre fragile. L'imprimeur est donc amené à nettoyer fréquemment ces rouleaux.Offset is a lithographic process based on a perfect hydrophilic-lipophilic balance. Hydrophilicity is a function of the state of pro preste wet rollers. These are loaded during printing not only greasy soils, but also solid soils (ink pigments, paper fluff, mineral fillers) thus breaking this fragile balance. The printer is therefore led to frequently clean these rollers.

Traditionnellement, le nettoyage des rouleaux mouilleurs s'effectuait en plusieurs opérations - lavage par brossage des rouleaux au petrole, au white spirit, ou
parfois même à l'essence d'automobile ; - rinçage à l'eau ; et - dépôt de blanc de craie d'Espagne (carbonate de calcium) qui absorbe
les substances grasses, puis s'élimine à l'eau.Traditionally, the cleaning of wet rollers was carried out in several operations - washing by brushing the rollers with petrol, with white spirit, or
sometimes even to automobile gasoline; - rinsing with water; and - deposit of white chalk from Spain (calcium carbonate) that absorbs
fatty substances, then removed with water.

Cette façon d'operer était longue, peu efficace et dangereuse ; elle nécessitait de grandes quantites d'hydrocarbures dommageables pour l'environnement.This way of operating was long, inefficient and dangerous; it required large quantities of hydrocarbons damaging the environment.

Plus récemment, l'utilisation de détergents industriels (du genre de ceux vendus sous la marque "Teepol") a été généralisée.More recently, the use of industrial detergents (of the type sold under the trademark "Teepol") has been generalized.

La présente invention propose des compositions de lavage ameliorees qui présentent une plus grande efficacité dans la pénétration des textiles salis et dans l'élimination des salissures. Selon l'importance des salissures à éliminer, ces compositions peuvent être utilisées pures ou diluées par des quantités d'eau variables. Elles présentent encore l'avantage d'être plus faciles à rincer à l'eau, car elles forment avec l'eau des solutiqns pseudo-colloidales diluables en toutes proportions. The present invention provides improved wash compositions that exhibit greater efficiency in penetration of soiled textiles and in soil removal. Depending on the amount of soil to be removed, these compositions can be used pure or diluted by varying amounts of water. They still have the advantage of being easier to rinse with water, because they form with water pseudo-colloidal solutions dilutable in all proportions.

D'une manière générale, les compositions considérées dans l'invention renferment - une proportion majeure (par exemple de 85 à 98 % en poids, d'au moins
un solvant choisi parmi les hydrocarbures liquides de type aliphati
que, alicyclique ou aromatique et éventuellement parmi les hydrocar
bures halogenes liquides ; - une proportion mineure (par exemple de 2 à 10 % en poids) d'au moins
un agent emulsifiant non ionique ; - eventuellement, une proportion mineure (par exemple d'au plus 5 %
en poids) d'un agent tensio-actif anionique ayant des propriétés
mouillantes ; ainsi que, avantageusement, - une proportion mineure (par exemple de 0,1 à 3 % en poids) d'un
stabilisant organique capable de réduire la tension interfaciale
des systèmes huile-eau, et induire une dispersion colloldale. In general, the compositions considered in the invention contain a major proportion (for example from 85 to 98% by weight, of at least
a solvent selected from liquid hydrocarbons of aliphatic type
than, alicyclic or aromatic and optionally among hydrocarbons
liquid halide fluids; a minor proportion (for example from 2 to 10% by weight) of at least
a nonionic emulsifier; - possibly a minor proportion (for example not more than 5%
by weight) of an anionic surfactant having
wetting; as well as, advantageously, a minor proportion (for example from 0.1 to 3% by weight) of a
organic stabilizer capable of reducing interfacial tension
oil-water systems, and induce a colloidal dispersion.

Les compositions considérées dans l'invention peuvent aussi contenir une proportion mineure d'eau, par exemple de 2 a 10 % en poids par rapport au poids de ladite composition anhydre.The compositions considered in the invention may also contain a minor proportion of water, for example from 2 to 10% by weight relative to the weight of said anhydrous composition.

On décrit ci-après plus précisément les constituants des compositions de nettoyage de l'invention.Hereinafter, the constituents of the cleaning compositions of the invention are described more precisely.

Comme solvants hydrocarbonés aliphatiques, alicycliques ou aromatiques on peut utiliser plus particulièrement le dodécane, le tetradécane, l'isopropylbenzène ou le para-cyméne, ou encore diverses coupes pétro lières, telles que des essences, des white-spirits désaromatisés ou non, des solvants naphta et des pétroles lampants desaromatisés ou non.As aliphatic, alicyclic or aromatic hydrocarbon solvents, dodecane, tetradecane, isopropylbenzene or para-cymene may be used more particularly, or various petroleum cuts, such as gasolines, white-spirits, deflavored or otherwise, solvents. naphtha and lamp oils, whether flavored or not.

On peut citer, comme convenant particulièrement bien une coupe dont l'intervalle de distillation est de 160 à 2100C et qui présente une composition volumique du type
n-alcanes : 20 - 25 %
isoalcanes : 35 - 45 %
cycloalcanes : 35 - 40 %
alkybenzènes : < 3.5 %
La présence d'au moins un hydrocarbure halogéné dans les compositions de l'invention est particulièrement avantageuse en ce qu'elle permet d'améliorer la stabilité des émulsions formées par dilution à l'eau.One particularly suitable is a section whose distillation range is from 160 to 2100 C and which has a volume composition of the type
n-alkanes: 20 - 25%
isoalkanes: 35 - 45%
cycloalkanes: 35 - 40%
Alkylbenzenes: <3.5%
The presence of at least one halogenated hydrocarbon in the compositions of the invention is particularly advantageous in that it makes it possible to improve the stability of the emulsions formed by dilution with water.

Comme exemples d'hydrocarbures halogénes liquides, on peut citer, le trichloroéthane-lll et le trichlorotrifluoroêthane. Le solvant ha logéné peut constituer jusqu'à 25% en poids de la composition.Examples of liquid halohydrocarbons are trichloroethane-III and trichlorotrifluoroethane. The halogenated organic solvent may constitute up to 25% by weight of the composition.

Les agents émulsifiants non-ioniques mis en jeu dans les compositions de nettoyage de l'invention sont choisis parmi les composés qui présentent une balance hydrophile-lipophile (BHL) de 1 à 14, de préférence de 8 a 12. A titre d'exemples de tels composes, on peut citer : BHL - le trioléate d'anhydrosorbitol 1,8 - le monooléate d'anhydrosorbitol 4,3 - l'alcool laurique éthoxylé (2 moles) 6,6 - le monooléate de polyéthylèneglycol 200 8,4 - le monooléate de polyethyleneglycol 300 9,5 - le monooléate de polyéthylèneglycol 400 11,0 - le trioléate de sorbitan ethoxyle (20 moles) 11,5 - l'huile de ricin éthoxylée (40 moles) 13,0
On peut aussi utiliser un mélange de deux ou plusieurs émulsifiants non ioniques.Dans ce cas, c'est la valeur deBHL globale qui doit être comprise entre les limites fixees précédemment. The nonionic emulsifying agents used in the cleaning compositions of the invention are chosen from compounds which have a hydrophilic-lipophilic balance (BHL) of 1 to 14, preferably 8 to 12. As examples such compounds include: BHL - anhydrosorbitol trioleate 1.8 - anhydrosorbitol monooleate 4.3 - ethoxylated lauric alcohol (2 moles) 6.6 - polyethylene glycol monooleate 200 8.4 - Polyethylene glycol monooleate 300 9.5 - Polyethylene glycol monooleate 400 11.0 - Ethoxyl sorbitan trioleate (20 moles) 11.5 - Ethoxylated castor oil (40 moles) 13.0
It is also possible to use a mixture of two or more nonionic emulsifiers. In this case, it is the overall BHL value which must be between the previously fixed limits.

La concentration totale préférée en emulsifiants non ioniques est comprise entre 2 et 5 % en poids.The preferred total concentration of nonionic emulsifiers is from 2 to 5% by weight.

Il est souvent avantageux de mettre aussi en jeu un agent tensio-actif anionique présentant de bonnes propriétes mouillantes. On le choisira plus particulièrement parmi les di--alkyl-sulfosuccinates de sodium, tels que le dioctyl, le dihexyl- ou le bis tridécyl- sulfosuccinate de sodium. Dans la plupart des cas, un tel agent tensio-actif anionique sera introduit dans les compositions de nettoyage de l'invention en une proportion de 0,5 à 4 % par rapport au poids de ladite composition. It is often advantageous to also use an anionic surfactant having good wetting properties. It will be chosen more particularly from sodium di-alkyl sulphosuccinates, such as dioctyl, dihexyl or sodium bis-tridecyl sulphosuccinate. In most cases, such anionic surfactant will be introduced into the cleaning compositions of the invention in a proportion of 0.5 to 4% based on the weight of said composition.

Comme stabilisant organique colloïdal capable de réduire la tension interfaciale des systèmes huile - eau, on utilise avantageusement la lécithine, en particulier la lécithine de soja en une proportion préforée de 0,7 à 1,6 % en poids.As a colloidal organic stabilizer capable of reducing the interfacial tension of oil-water systems, lecithin, especially soy lecithin, is advantageously used in a pre-drilled proportion of 0.7 to 1.6% by weight.

On peut aussi utiliser la gélatine, la gomme arabique, l'agar-agar ou des polysaccharides provEnant de cultures microbiennes en fermenteurs.It is also possible to use gelatin, gum arabic, agar or polysaccharides from microbial cultures in fermenters.

Pour le nettoyage des objets salis, tels que les textiles naturels ou synthétiques constituant l'habillage des rouleaux mouilleurs de machines à imprimer (de type "offset"), on met lesdits objets en contact avec une composition de nettoyage telle que décrite dans l'invention, celle-ci pouvant être utilisée telle quelle ou diluee par des quantités d'eau variables, formant alors une émulsion stable. La proportion d'eau ajoutée peut être par exemple de 50 à 300 % par rapport au poids de la composition.For the cleaning of soiled objects, such as natural or synthetic textiles constituting the coating of the damping rollers of printing machines (offset type), said objects are brought into contact with a cleaning composition as described in FIG. the invention can be used as such or diluted by varying amounts of water, thus forming a stable emulsion. The proportion of water added may be, for example, from 50 to 300% relative to the weight of the composition.

te nettoyage se fait en genéral par brossage. Grâce à la présence de l'emulsifiant et éventuellement du tensio-actif, les solvants pénètrent le tissu à nettoyer et en detachent efficacement les salissures. On procède ensuite à un rinçage à l'eau, par lequel on obtient une émul- sion laiteuse huile-dans-l'eau dont le diametre moyen des particules (gouttelettes) est de l'ordre de quelques microns. Cette émulsion stable riche en eau, est elle même douée de propriétés de lavage.cleaning is usually done by brushing. Thanks to the presence of the emulsifier and possibly the surfactant, the solvents penetrate the fabric to be cleaned and effectively detach the dirt. This is followed by a rinsing with water, whereby a milky oil-in-water emulsion is obtained, the average diameter of the particles (droplets) of which is of the order of a few microns. This stable emulsion rich in water, is itself endowed with washing properties.
