KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die vorliegende Erfindung bezieht sich aufThe present invention relates to ein Verfahren zur Herstellung der wirksamen Masse von Bleisammlerelektroden und bezweckt, die Festigkeit sowie den Wirkungsgrad und den Nutzeffekt derselben zu vergrößern.a process for the production of the effective mass of lead collector electrodes and aims, to increase the strength as well as the efficiency and the efficiency of the same. Um die wirksame Masse härter und zusammenhängender zu machen, wird das Bleioxyd in Form einer Paste mit verdünnter Schwefelsäure unter Zusatz einer geringen Menge eines in Schwefelsäure unlöslichen Bindemittels angerührt. Als Bindemittel verwendet man an Stelle der bisher verwendeten Teerdestillationsrückstände oder fossilen Harze, wie des Bernsteins, Erdpech, d.h. Bitumen (zweckmäßig Trinidadbitumen), welches man in einem leichten Kohlenwasserstoff, zweckmäßig Benzol, auflöst. Diese Erdpechlösung verdünnt man mit Alkohol, um sie mit verdünnter Schwefelsäure vermischen zu können. Die erforderliehen Verhältnisse sind von Fall zu Fall zu bestimmen.To make the effective mass harder and more cohesive, the lead oxide is used in the form of a paste with dilute sulfuric acid with the addition of a small amount of a binder that is insoluble in sulfuric acid touched. The tar distillation residues used up to now are used as binders or fossil resins, such as amber, earth pitch, i.e. bitumen (suitably Trinidad bitumen), which can be combined in one light hydrocarbon, expediently benzene, dissolves. This pitch solution is diluted with alcohol in order to be able to mix them with dilute sulfuric acid. The required Relationships are to be determined on a case-by-case basis. Man löst z. B. 28 g Erdpech in 280 g Benzol auf und verdünnt diese Lösung mit 1120g Alkohol (denaturiert); diese verdünnte Lösung gibt man zu einer genügenden Menge verdünnter Schwefelsäure von ungefähr 1,170 spez. Gewicht, um mit 45 kg Bleioxyd eine Paste anrühren zu können. Man kann auch die Schwefelsäurelösung weglassen, wobei dann 2,8 kg verdünnter Erdpechlösung auf 45 kg Bleioxyd erforderlich sind. Ebenso kann man auch den Alkohol weglassen, in welchem Falle man 2,8 kg Erdpechbenzollösung auf 45 kg Bleioxyd verwendet, um mit einer entsprechenden Menge verdünnter Schwefelsäure eine gut zu verarbeitende Paste zu erhalten. Nachdem man die so erhaltene Paste auf den Träger aufgestrichen hat, wird sie bei niedriger Temperatur vollständig getrocknet, wobei das zum Auflösen des Erdpeches verwendete Lösungsmittel verdunstet, während das Erdpech als Bindemittel für die wirksame Masse zurückbleibt. Die Bindekraft des in den angegebenen Mengen zugesetzten Erdpeches erteilt der Masse solche Härte, daß ihre Lebensdauer wesentlich erhöht wird, ohne daß die Kapazität der Batterie, ausgedrückt in Amperestunden, wesentlich verringert wird; wenn man jedoch die Menge des zugesetzten Erdpeches wesentlich erhöht, nimmt zwar die Härte und Lebensdauer der Masse noch mehr zu, die Kapazität wird jedoch entsprechend verringert.One solves z. B. 28 g of pitch in 280 g of benzene and diluted this solution with 1120g Alcohol (denatured); this diluted solution is added to a sufficient amount of the diluted solution Sulfuric acid of about 1.170 spec. Weight to make a paste with 45 kg of lead oxide to be able to touch. The sulfuric acid solution can also be omitted, in which case 2.8 kg of dilute earth pitch solution to 45 kg Lead oxide are required. Likewise, one can also omit the alcohol, in which case 2.8 kg of pitch benzene solution to 45 kg of lead oxide are used to make a corresponding Amount of dilute sulfuric acid to obtain a paste that is easy to process. After this the paste thus obtained has been spread on the support, it becomes at a low temperature completely dried, the solvent used to dissolve the earth pitch evaporates, while the pitch remains as a binding agent for the effective mass. The binding force of the earth pitch added in the specified amounts gives the mass such hardness that their service life is significantly increased without affecting the capacity of the Battery, expressed in ampere-hours, is significantly reduced; but if you have the The amount of added pitch increases significantly, although the hardness and service life decrease the mass even more, but the capacity is reduced accordingly. Die Platten werden in üblicher Weise formiert. Zur Herstellung der Elektroden verwendet man zweckmäßig Gitterträger. Die in den Zellen der Gitter enthaltene wirksame Masse wird in dünner Schicht aufgetragen, so daß fast durch die ganze Masse hindurch eine chemische Wirkung eintritt, wobei diese Wirkung vollständig und gleichmäßig zum Ausdruck kommt, und in dieser Weise das Werfen der Platten fast völlig vermieden und der Anteil der wirksamen Masse, der tatsächlich zur Wirkung kommt, bedeutend erhöht wird.The plates are formed in the usual way. Used to make the electrodes one expedient lattice girders. The effective contained in the cells of the grid The mass is applied in a thin layer so that a chemical effect occurs, this effect being fully and evenly expressed comes, and in this way the throwing of the plates is almost completely avoided and the stake the effective mass that actually takes effect is significantly increased. PateNT-AνSPRUcη :PateNT-AνSPRUcη: Verfahren zur Herstellung der wirksamen Masse, für Bleisammlerelektroden, dadurchProcess for the production of the effective mass, for lead collector electrodes, thereby gekennzeichnet, daß die Bleioxyde mit einer Lösung von Bitumen (zweckmäßig Trinidadbitumen) in einem leicht siedenden Kohlenwasserstoff, z. B. Benzo! unter Zusatz von Alkohol und zweckmäßig auch unter Zusatz von verdünnter Schwefelsäure, gemischt werden, wobei nach dem Trocknen und Verdunsten des Lösungsmittels eine harte und zusammenhängende Masse zurückbleibt, welche sodann in bekannter Weise in verdünnter Schwefelsäure gehärtet und formiert werden kann.characterized that the lead oxides with a solution of bitumen (appropriately Trinidad bitumen) in a low boiling hydrocarbon, e.g. B. Benzo! with the addition of Alcohol and expediently also with the addition of dilute sulfuric acid, mixed after drying and evaporation of the solvent a hard and coherent mass remains, which is then hardened and formed in a known manner in dilute sulfuric acid can be.
