Description
Matière pigmentaire et procédé de fabrication de cette matière Selon les procédés habituels de fabrication d'encres d'imprimerie, les pigments se présentent sous forme de poudre, sont t broyés avec divers résines, solvants et liants dans des broyeurs à billes ou a galets ou des appareils similaires. Ce broyage pre- sente suivant les pigments l'inconvénient d'tre particulierement long (24-40 heures) et donne lieu au moment du chargement du pigment dans les broyeurs à la formation de poussière genante par suite notamment de la très basse densité de certains d'entre eux. Pigmentary material and process for manufacturing this material According to the usual processes for manufacturing printing inks, the pigments are in the form of powder, are ground with various resins, solvents and binders in ball or pebble mills or similar devices. This grinding has, depending on the pigments, the disadvantage of being particularly long (24-40 hours) and gives rise, when loading the pigment into the grinders, to the formation of troublesome dust as a result in particular of the very low density of certain of them.
La présente invention a pour objet une matière pigmentaire ne présentant pas ces inconvénients et un procédé pour sfa fabrication. The present invention relates to a pigmentary material not having these disadvantages and a process for its manufacture.
La matière pigmentaire est caractérisée par le fait qu'elle est constituée par une dispersion d'un pigment dans au moins un liant asphaltique ou bitumineux. The pigment material is characterized in that it consists of a dispersion of a pigment in at least one asphaltic or bituminous binder.
Son procédé de fabrication est caractérisé par le fait qu'on disperse à chaud par malaxage un pigment dans au moins un liant asphaltique ou bitumineux. Its manufacturing process is characterized by the fact that a pigment is dispersed while hot by mixing in at least one asphaltic or bituminous binder.
Cette matière peut tre dissoute à froid par simple agitation dans un solvant approprie pour tre employé, sans broyage en forme de dissolution pour la fabrication des encres à imprimerie. This material can be dissolved in the cold by simple stirring in an appropriate solvent to be used, without grinding in the form of a solution for the manufacture of printing inks.
La matiere pigmentaire selon l'invention peut comprendre une dispersion de pigments organiques ou minéraux, et aussi du noir de pétrole ou du noir à gaz, pouvant tre employés soit en poudre, soit en pâte aqueuse dans des liants asphaltiques ou bitumineux. Ces liants peuvent etre ainsi combines à d'autres dérivés bitumineux tels que le brai, poix minérale ou végétale ou avec du brai sulfitique. Le liant peut également tre combine avec des résines naturelles, des résines naturelles traitées, des résines synthétiques, ou encore avec des mouillants ioni- ques et non ioniques. The pigmentary material according to the invention can comprise a dispersion of organic or mineral pigments, and also petroleum black or gas black, which can be used either in powder or in aqueous paste in asphaltic or bituminous binders. These binders can thus be combined with other bituminous derivatives such as pitch, mineral or vegetable pitch or with sulphite pitch. The binder can also be combined with natural resins, treated natural resins, synthetic resins, or else with ionic and nonionic wetting agents.
Le procédé de fabrication de cette matière pig mentaireconsisteg & neralementadispeTsorä une température comprise entre 80-2000 environ, par malaxage d'une duree de quelques heures, un pigment dans un liant asphaltique ou bitumineux et ceci avec ou sans adjonction de résine et de mouillant. On utilise ladite matière, sans broyage, dans la fabrication des encres à imprimerie en la dissolvant dans un solvant approprie. The manufacturing process for this pigmentary material consists generally of a temperature between 80 and 2000 approximately, by mixing a pigment in an asphalt or bituminous binder for a period of several hours, with or without the addition of resin and wetting agent. Said material is used, without grinding, in the manufacture of printing inks by dissolving it in an appropriate solvent.
L'emploi de la matière pigmentaire selon l'inven- tion simplifie et raccourcit considérablement la pire- paration des encres d'imprimerie. Etant soluble, cette matière permet de supprimer les longs broyages habi tuellement néceslsaires, d'éviter la formation de pous sieres et d'augmenter sensibloment le brillant des encres. Les encres ainsi obtenues sont en outre plus homogènes et plus fines que les encres connues jus qu'à présent. The use of the pigment material according to the invention considerably simplifies and shortens the worst preparation of printing inks. Being soluble, this material makes it possible to eliminate the long grindings usually necessary, to avoid the formation of dust and to significantly increase the gloss of the inks. The inks thus obtained are moreover more homogeneous and finer than the inks known hitherto.
La matière pigmentaire possède une force colorante bien superieure ä celle des pigments en poudre connus, ce qui est du notamment à la dispersion du pigment à la chaleur. The pigmentary material has a coloring force much higher than that of the known powder pigments, which is due in particular to the dispersion of the pigment under heat.
A titre d'exemple on pourrait disperser 20 à 40 kg de noir de pétrole avec 65 à 100 kg de produit asphaltique et 15 à 20 kg de resine naturelle traitée telle que du résinate de calcium ainsi que 2 à 10 % de moulant non ionique. Le tout sera malaxe pendant 2-3 heures environ. Le mélange une fois refroidi sera dissous dans un solvant tel que du xylol ou de l'essence de pétrole ou encore dans un mélange de ces deux produits. Il pourra ainsi tre employé par simple mélange à froid avec les autres ingredients habituels dans la fabrication des encres d'imprimerie. By way of example, 20 to 40 kg of petroleum black could be dispersed with 65 to 100 kg of asphaltic product and 15 to 20 kg of treated natural resin such as calcium resinate as well as 2 to 10% of nonionic molding agent. Everything will be kneaded for about 2-3 hours. The mixture, once cooled, will be dissolved in a solvent such as xylol or petroleum spirit or else in a mixture of these two products. It can thus be used by simple cold mixing with the other usual ingredients in the manufacture of printing inks.
