Abstract

1. Use of copolymers which, based on the weight of the polymers, contain 40 to 90% of acrylic or methacrylic acid and 60 to 10% of maleic acid as copolymerized units, or of their alkali metal or ammonium salts as incrustation inhibitors in detergents.

Description

In modernen Waschmittelformulierungen muß bekanntlich wegen der Gefahr der Eutrophierung der Gewässer der Gehalt an Phosphaten zumindest stark herabgesetzt werden. Um die Waschwirkung aber auf dem gleichen Stand wie bisher halten zu können, müssen Phosphatersatzstoffe eingesetzt werden. Von diesen sind vor allem Nitrilotriessigsäure, Polycarbonsäuren, wie Gluconsäure, Citronensäure, sodann polymere Säuren, wie Poly(meth)acrylsäure, Maleinsäure/Vinyläther--Copolymerisate und neuerdings auch Polymaleinsäuren bekannt geworden. Neueste Entwicklungen stellt der Einsatz von anorganischen wasserunlöslichen Aufbaustoffen dar. Es handelt sich um die in der DE-OS 24 12 837 beschriebenen Alumosilikate vom Typ Zeolith A.In modern detergent formulations, it is known that the phosphate content must be at least greatly reduced because of the risk of eutrophication of the waters. In order to keep the washing effect at the same level as before, phosphate substitutes must be used. Of these, nitrilotriacetic acid, polycarboxylic acids, such as gluconic acid, citric acid, and then polymeric acids, such as poly (meth) acrylic acid, maleic acid / vinyl ether copolymers, and more recently also polymaleic acids, have become known. The latest developments are the use of inorganic water-insoluble building materials. These are the aluminosilicates of the zeolite A type described in DE-OS 24 12 837.

Eine Zusammenfassung über Möglichkeiten des Phosphatersatzes findet sich in Angew. Chemie 87, Seiten 115 bis 142 (1975).A summary of the possibilities of phosphate replacement can be found in Angew. Chemie 87, pages 115 to 142 (1975).

Nun sind aber die Phosphate nicht nur hervorragende Builder mit Komplexierungsvermögen, sondern sie wirken auch als Sekundärwaschmittel, d.h. sie verhindern auch die Ablagerung von anorganischen, unlöslichen Salzen auf dem PGewebe. Diese Ablagerung wird Inkrustation genannt, und es hat sich gezeigt, daß keiner der bisher verwendeten Phosphatersatzstoffe hinsichtlich der Gesamtwirkung als Builder und des Inhibierungsvermögens gegenüber der Inkrustation in der Lage ist, Phosphate gleichwertig zu ersetzen. Man mußte daher Zusatzstoffe einsetzen, um des Problems der Inkrustierung Herr zu werden.However, the phosphates are not only excellent builders with complexing power, they also act as secondary detergents, ie they also prevent the deposit of inorganic, insoluble salts on the P tissue. This deposit is called incrustation, and it has been shown that none of the phosphate substitutes used hitherto are capable of replacing phosphates on an equivalent basis in terms of their overall action as a builder and in terms of their inhibition capacity against incrustation. Additives had to be used to deal with the problem of incrustation.

Aus der DE-PS 697 945 und DE-PS 540 101 sind Polyacrylsäuren und Copolymerisate der Maleinsäure mit anderen copolymerisierbaren Monomeren (verseifte Maleinsäureanhydrid-Copolymerisate) als Zusätze in Waschmitteln bekannt, und es heißt in der dortgenannten Publikation, daß sich Textilien, die mit derartigen Waschmitteln gewaschen seien, durch einen weichen Griff auszeichneten. Es hat sich gezeigt, daß diese Griffverbesserung zwar auf eine verminderte Inkrustation zurückzuführen ist, jedoch wiesen diese Gewebe einen immer noch zu hohen Aschegehalt auf, d.h. die Inkrustation war noch zu stark.From DE-PS 697 945 and DE-PS 540 101, polyacrylic acids and copolymers of maleic acid with other copolymerizable monomers (saponified maleic anhydride copolymers) are known as additives in detergents, and it is mentioned in the publication cited there that textiles containing such Detergents are washed, characterized by a soft handle. It has been shown that this improvement in grip can be attributed to reduced incrustation, but these fabrics still had an ash content that was still too high, i.e. the incrustation was still too strong.

Neuerdings wurden auch reine Homopolymerisate der Maleinsäure mit niedrigem Molgewicht für diesen Zweck getetet, und es wurden auch, wie die DE-OS 28 40 169 lehrt, gewisse Fortschritte erzielt, aber auch diese reichten indes noch nicht aus.Recently, pure homopolymers of maleic acid with a low molecular weight have also been tested for this purpose, and, as taught in DE-OS 28 40 169, certain progress has been made, but these have not yet been sufficient.

Das Ziel der vorliegenden Erfindung bestand darin, Stoffe aufzufinden, die in phosphatfreien oder -armen Waschmitteln, in möglichst geringen Mengen zugesetzt, die Inkrustation weitestgehend verhindern.The aim of the present invention was to find substances which, in the smallest possible amounts, added in low-phosphate-free or low-phosphate detergents largely prevent incrustation.

Dieses Ziel wurde überraschenderweise mit Copolymerisaten erreicht, die 40 bis 90 Gew.% (Meth)acrylsäure und 60 bis 10 Gew.% Maleinsäure als Monomerbausteine enthalten. Geeignet sind auch deren Alkali-, vorzugsweise Natrium- und Ammoniumsalze. 'This goal was surprisingly achieved with copolymers containing 40 to 90% by weight of (meth) acrylic acid and 60 to 10% by weight of maleic acid as monomer units. Also suitable are their alkali metal, preferably sodium and ammonium salts. '

Die Copolymerisate zeigen gegenüber reiner Polyacrylsäure und gegenüber reiner Polymaleinsäure ein sprunghaft verbessertes Inhibierungsvermögen gegenüber Inkrustationen bei Textilwaschprozessen mit phosphatfreien und phosphatarmen Waschmitteln.Compared to pure polyacrylic acid and pure polymaleic acid, the copolymers have an abruptly improved inhibition capacity against incrustations in textile washing processes with phosphate-free and low-phosphate detergents.

Dieser Befund ist außerordentlich überraschend, da kaum anzunehmen war, daß Copolymerisate derart sprunghafte Än- derungen ihrer Eigenschaften zeigen, nachdem die reinen Homopolymerisate ihrer Monomerbausteine wesentlich schlechtere Wirkungen zeigen.This finding is extremely surprising, there was hardly likely that copolymers such abrupt Su - ments show their properties after the pure homopolymers their monomeric show substantially worse effects.

Die Copolymerisate erhält man in an sich bekannter Weise durch Copolymerisation von Maleinsäureanhydrid mit (Meth)-acrylsäure in den angegebenen Mengenverhältnissen (berechnet als Maleinsäure) und anschließende Verseifung. Bevorzugt wählt man solche Mengen, daß im Copolymerisat 45 bis 85 Gew.% (Meth)acrylsäure und 55 bis 15 Gew.% Maleinsäure anwesend sind.The copolymers are obtained in a manner known per se by copolymerization of maleic anhydride with (meth) acrylic acid in the proportions given (calculated as maleic acid) and subsequent saponification. Amounts are preferably chosen such that 45 to 85% by weight of (meth) acrylic acid and 55 to 15% by weight of maleic acid are present in the copolymer.

Die Polymerisation wird durch radikalische Initiierung in Lösung, Suspension oder als Fällungspolymerisation durchgeführt.The polymerization is carried out by free radical initiation in solution, suspension or as precipitation polymerization.

Die Polymerisationstemperaturen liegen bei etwa 50 bis 200, vorzugsweise 100 bis 150°C. Als Initiatoren kommen die üblichen radikalbildenden Verbindungen wie Dialkylperoxide, Alkylhydroperoxide, Perester, Diacylperoxide und Azoverbindungen, wie Azoisobutyronitril in Betracht.The polymerization temperatures are about 50 to 200, preferably 100 to 150 ° C. Suitable initiators are the customary radical-forming compounds, such as dialkyl peroxides, alkyl hydroperoxides, peresters, diacyl peroxides and azo compounds, such as azoisobutyronitrile.

Die erhaltenen Copolymerisate in unverseiftem Zustand weisen bevorzugt K-Werte von 10 bis 40 auf, die gemäß Fikentscher, Cellulosechemie 13, Seite 58 in Methyläthylketon bei 25°C bestimmt werden.The copolymers obtained in the unsaponified state preferably have K values of 10 to 40, which according to Fikentscher, Cellulosechemie 13, page 58 can be determined in methyl ethyl ketone at 25 ° C.

Die Copolymerisate werden Waschmitteln - bezogen auf Trockensubstanz - in Mengen von 0,5 bis 10, vorzugsweise 2 bis 6 Gew.% zugesetzt.The copolymers are added to detergents, based on dry substance, in amounts of 0.5 to 10, preferably 2 to 6,% by weight.

Da die Waschmittel alkalisch reagieren, liegen die Copolymerisate in Form der entsprechenden Alkalisalze vor; sie können auch direkt als Alkali-, vorzugsweise Natriumsalz oder Ammoniumsalz eingesetzt werden.Since the detergents react alkaline, the copolymers are in the form of the corresponding alkali salts; they can also be used directly as the alkali, preferably sodium or ammonium salt.
