Description

Auf den Oberflächen, von Gegenständen aller Art, die der dauernden Einwirkung von Wasser ausgesetzt sind., bildet sich nach einer gewissen Zeit ein Pflanzenbewudhs, .der in der Regel aus Algen besteht. Ein .derartiger Bewuchs· ist unerwünscht, da besonders stehendes (Wasser dadurch unansehnlich und undurchsichtig wird.On the surfaces of everyone's objects Species that are permanently exposed to the action of water are formed after a certain period of time a plant life, which is usually made up of algae consists. Such vegetation is undesirable because it makes stagnant water unsightly and becomes opaque.

Es wurde nun .gefunden, daß man die Ausbildung eines Pflanzenbewuchses auf Gegenständen, die der Einwirkung von Wasser ausgesetzt sind, verhindern kann, wenn, man auf der Oberfläche solcher Gegenstände schwerlösliche Salze von carboxylgruppenfaaltigen Wuchsstoffen fixiert. Als Beispiele für geeignete carboxylgruppenhaltige Wuchsstoffe sind vorzugsweise 2, /(.-Dichlorphenoxyessigsäure, ferner andere Phenoxyalkylcarbons-äuren sowie /7-Naphthyl- und /Mndolylessigsäure zu nennen. Von den schwerlöslichen Salzen dieser Verbindungen sind insbesondere die Kupfersalze geeignet.It has now been found that the formation of vegetation on objects that the Exposure to the action of water can prevent if, one on the surface of such Objects sparingly soluble salts of carboxyl-containing growth substances fixed. As examples for suitable growth substances containing carboxyl groups are preferably 2, /(.- dichlorophenoxyacetic acid, also to mention other phenoxyalkylcarboxylic acids and / 7-naphthyl and / mndolyl acetic acid. Of the sparingly soluble salts of these compounds, the copper salts are particularly suitable.

Man kann aber auch Barium-, Calcium- oder ao Quecksilbersalze u. dgl. verwenden.But you can also use barium, calcium or ao Use mercury salts and the like.

Zur Fixierung der schwerlöslichen Wuchsstoffe dienen in erster Linie Lacke auf Basis von trocknenden ölen, ölhaltigen Alkydharzen oder von Lösungen oder Dispersionen von Polymerisations- as kunststoffen oder von Chlorkautschuk. .Man kann auch Mischungen derartiger Stoffe verwenden. !Zweckmäßig setzt man solchen Lacken etwa ι bis 15% der schwerlöslichen Salze der carboxylgruppenhaltigen Wuchsstoffe, berechnet auf das lösungsmittelfreie Bindemittel, zu und trägt dann die Lacke nach bekannten Verfahren., z. B. durch Streichen oder Spritzen, auf. Die Lacke können auch noch weitere Zusatzstoffe, z. B. Pigmente, Weichmacher u.dgl., enthalten. Man kann aber auch andere Bindemittel für die Fixierung der schwerlöslichen Wuchsstoffsalze verwenden, z. B. Gips oder Zement.Paints based on drying are primarily used to fix the sparingly soluble growth substances oils, oil-containing alkyd resins or solutions or dispersions of polymerization as plastics or chlorinated rubber. Mixtures of such substances can also be used. It is advisable to use such lacquers about ι to 15% of the sparingly soluble salts of the growth substances containing carboxyl groups, calculated on the solvent-free Binder, and then wears the paints by known methods., Z. B. by Brush or spray. The paints can also contain other additives such. B. Pigments, Plasticizers and the like. But you can also use other binders for fixing the Use sparingly soluble growth substance salts, e.g. B. plaster of paris or cement.

Nach dem Verfahren können beispielsweise Wasserbecken, Holzboote, Schiffsplanken, Schiffe u. dgl. gegen den Bewuchs· mit Pflanzen, geschützt werden.According to the method, for example, water basins, wooden boats, ship planks, ships and the like. Protected against vegetation will.

Die in dem, nachstehenden Beispiel angegebenen Teile sind Gewidhtsteile.The parts given in the example below are by weight.

Beispielexample

Es· wird eine LackmisChung aus folgenden Stoffen hergestellt:It becomes a mixture of the following Fabrics made:

500 Teile eines Mischpolymerisates aus Vinylchlorid und Vinylisobutyläther, 125 Teile eines Kunstharzes aus Cyclohexanon, 50 Teile chloriertes Diphenyl mit einem Chlorgehalt von 58 bis 59%, 4OoTeileEssigester, 200 Teile Butylacetat, 300Teile Toluol, 500 Teile Benzin, 60 Teile des Kupfersalzes der 2, 4-Dichlorphenoxyessigsäure, 30 Teile Chromöxyd und 80 Teile Kieselgel.500 parts of a copolymer of vinyl chloride and vinyl isobutyl ether, 125 parts of a Synthetic resin made from cyclohexanone, 50 parts of chlorinated diphenyl with a chlorine content of 58 to 59%, 40 parts of ethyl acetate, 200 parts of butyl acetate, 300 parts Toluene, 500 parts of gasoline, 60 parts of the copper salt of 2,4-dichlorophenoxyacetic acid, 30 parts of chromium oxide and 80 parts of silica gel.

Mit diesem Lack werden die !Wände eines Wasserbeckens aus Beton gestrichen. Während sich in einem Wasserbecken, das nicht mit diesem Lack bestrichen ist, schon nach wenigen Tagen Algen ansetzen, ist das bestrichene Becken auch nach mehreren Wochen frei von Algenbewuchs·.The walls of a concrete water basin are painted with this varnish. While in a water basin that has not been coated with this varnish, algae after just a few days start, the coated tank is free of algae growth even after several weeks.
