Den .foreliggende opfindelse angår en fremgangsmåde til fremstilling af pigmentholdige belægningsmasser til carbonpapir ved blanding af vandige voksemulsioner, der indeholder voks, carbon black, olie og oliesyre.The present invention relates to a process for the preparation of pigment-containing coating compositions for carbon paper by mixing aqueous wax emulsions containing wax, carbon black, oil and oleic acid.

Råpapiret til tyndt carbongennemslagspapir kan f.eks. være såkaldt carbonsilke. Det af klude eller cellulose bestående papir med en vægt på 10 til 20 g/m2 skal være sejt og pore- og knudefrit.For example, the raw paper for thin carbon penetration paper may. be so-called carbon silk. The tissue or cellulose paper weighing 10 to 20 g / m2 must be tough and pore- and knot-free.

22

Rent celluloseråpapir med en fladevægt på 30 til 40 g/m anvendes til fremstilling af specielt carbongennemslagspapir, bl.a. til bogføringsmaskiner. Til belægning af råpapiret benyttes pigmenter (f. eks. carbon black, miloriblåt eller paraffin-carbon-black-emulsioner.Pure cellulose paper having a surface weight of 30 to 40 g / m is used for the production of special carbon punch paper, i.a. for bookkeeping machines. Pigments (eg carbon black, milori blue or paraffin-carbon black emulsions are used for coating the raw paper).

2 149132 som blandes med voks, harpikser og olier. Til forhindring af sammenrulning ved brug forsynes papirets bagside som oftest endnu med et voks- eller plastlag. Af det som oftest anvendte "flergangs-carbon-papir" kræves klare og godt læsbare gennemslag, samt en gentagen anvendelsesmulighed for det enkelte blad. Såkaldt "éngangs-carbonpapir", som man kun anvender én gang, benyttes til færdige formularsæt. Til håndgennemskrift (gennemskrivningspapir), til overtryksmetoden (sprit-carbon) og til bogføringsmaskiner benyttes tykkere specialsorter .2 149132 which is mixed with wax, resins and oils. To prevent roll-up during use, the back of the paper is usually still provided with a wax or plastic layer. Of the most commonly used "multipurpose carbon paper", clear and easily readable punches are required, as well as a repeated use for each sheet. So-called "disposable carbon paper", which is used only once, is used for finished form sets. Thicker special types are used for handwriting (transcript paper), for the overprinting method (alcohol-carbon) and for bookkeeping machines.

Det er kendt at fremstille pigmentholdige belægningsmasser til carbonpapir, hvilke masser påføres på råpapiret ved strygningseller trykkemetoden, idet man anvender massen i smeltet, flydende tilstand eller i en organisk opløsningsmiddelfase.It is known to produce pigment-containing coating compositions for carbon paper which are applied to the raw paper by the ironing or printing method, using the pulp in the molten, liquid state or in an organic solvent phase.

De kendte fremgangsmåder har imidlertid den ulempe, at de krarver et stort energiforbrug til frembringelse og opretholdelse af den smeltede, flydende tilstand eller til bortsugning, genvinding eller fjernelse af de mest sundhedsfarlige opløsningsmidler.However, the known methods have the disadvantage that they require a large amount of energy consumption to produce and maintain the molten, liquid state or to absorb, recover or remove the most hazardous solvents.

Formålet med opfindelsen er at tilvejebringe en fremgangsmåde til fremstilling af pigmentholdige belægningsmasser til carbonpapir, ved hvilken man hverken behøver at arbejde med masserne i smeltet, flydende tilstand eller i en organisk opløsningsmiddelfase.The object of the invention is to provide a process for the preparation of pigment-containing coating compositions for carbon paper, in which one does not need to work with the masses in the molten, liquid state or in an organic solvent phase.

Dette opnås ved fremgangsmåden ifølge opfindelsen, der er ejendommelig ved, at man anvender vand i en mængde mellem 36 og 69 vægt%, beregnet på den samlede blanding, og eventuelt under blandingen tilsætter en pyrogent fremstillet kiselsyre.This is achieved by the process according to the invention, characterized in that water is used in an amount between 36 and 69% by weight, based on the total mixture, and optionally, during the mixing, a pyrogenic silica is added.

Fra tysk fremlæggelsesskrift nr. 1.242.642 og tysk offentliggørelsesskrift nr. 1.421.444 kendes ganske vist fremgangsmåder af den omhandlede art, men ved disse fremgangsmåder anvendes der vand i betydelig større mængder end ved fremgangsmåden ifølge den foreliggende opfindelse, således at tørringstrinnet ved anvendelse af de ved de kendte fremgangsmåder fremstillede blandinger er besværligere og kræver mere energi.German Patent Laid-Open No. 1,242,642 and German Laid-Open Publication No. 1,421,444 admittedly have known processes of the kind in question, but in these methods water is used in considerably greater quantities than in the process of the present invention, so that the drying step using the mixtures prepared by the known methods are more difficult and require more energy.

Blandingens komponenter kan blandes med hinanden i et forhold fra 50:30:40 til 50:60:10. Ved en foretrukken udførelsesform for fremgangsmåden ifølge opfindelsen kan blandingens komponenter blandes med hinanden i forholdet 50:50:20. Som olie kan der også til den totale blanding sættes en blanding af knogleolie, olein og ricinusolie i forholdet 40:40:20.The components of the mixture can be mixed with one another in a ratio of 50:30:40 to 50:60:10. In a preferred embodiment of the process according to the invention, the components of the mixture can be mixed in a ratio of 50:50:20. As an oil, a mixture of bone oil, olein and castor oil can also be added in the ratio 40:40:20.

3 149132 På basis af fremgangsmåden ifølge opfindelsen er det muligt at fremstille pigmentholdige belægningsmasser til carbonpapir uden at måtte anvende en energiforbrugende smelteflydning eller sundhedsfarlige organiske opløsningsmidler.Based on the process of the invention, it is possible to produce pigment-containing coating compositions for carbon paper without having to use an energy-consuming melt flow or hazardous organic solvents.

Udtrykket "voks" er en teknologisk samlebetegnelse for en række naturlige eller syntetisk fremstillede stoffer, der i reglen har følgende egenskaber: Ved 20°C æltbare faste eller skøre hårde, grovkrystallinske til finkrystallinske, gennemskinnelige til opake, dog ikke glasagtige, over 40°C smeltbare uden sønderdeling og ikke trådtrækkende, stærkt temperaturafhængig konsistens og opløselighed, og under let tryk polerbare (jfr. Ullmanns Enzyklopådie der technischen Chemie, 18. bind, 3. oplag, side 263 til 305/1967).The term "wax" is a technological collective term for a variety of natural or synthetically produced substances, which usually have the following properties: At 20 ° C kneadable solid or brittle hard, coarse crystalline to fine crystalline, translucent to opaque, but not glassy, above 40 ° C meltable without decomposition and non-tensile, highly temperature-dependent consistency and solubility, and lightly polishable (cf. Ullmann's Enzyklopådie der technischen Chemie, 18th volume, 3rd edition, pages 263 to 305/1967).

Tilsætningen af pyrogentfremstillet kiselsyre kan bibringe de pigmentholdige belægningsmasser bedre stabilitet og lagringsdygtighed og desuden hos gennemslagene give større skarphed og farvedybde. Den pyrogent franstillede kiselsyre kan tilsættes i mængder på 0,1 til 3 vægt-%, beregnet på den totale blanding.The addition of pyrogen-made silica can give the pigment-containing coating compositions better stability and storage capacity and, moreover, at the breakthroughs, give greater sharpness and color depth. The pyrogenically produced silicic acid can be added in amounts of 0.1 to 3% by weight, based on the total mixture.

Fremgangsmåden ifølge opfindelsen belyses nærmere ved hjælp af de efterfølgende eksempler.The process according to the invention is further elucidated by the following examples.
