Description
Wurzelabweisende Dichtungen und Vergußmassen für Wasser-, insbesondere Abwasserleitungen Es ist bekannt, dem Dichtungsmaterial, meist bituminöse VerguBmassen, bei Wasser-, insbesondere Abwasserleitungen, zum Schutz gegen den Bewuchs und das Eindringen von Pflanzenwurzeln Pentachlorphenol zuzusetzen. Dies hat jedoch einige Nachteile. Da das Vergießen der Bitumenmassen bei Temperaturen erfolgt, bei denen Pentachlorphenol bereits erheblich verdampft, treten merkbare Verluste an diesem Stoff ein. Da es zudem nicht selten vorkommt, daß solche Massen mehrmals aufgeschmolzen werden, besteht die Gefahr, daß das Pentachlorphenol praktisch vollständig verlorengeht. Root-repellent seals and potting compounds for water, in particular Sewer pipes It is known that the sealing material, mostly bituminous sealing compounds, in the case of water pipes, especially sewer pipes, to protect against vegetation and that Add pentachlorophenol to penetration of plant roots. However, this has a few Disadvantage. Since the pouring of the bitumen masses takes place at temperatures at which If pentachlorophenol has already evaporated considerably, noticeable losses occur in this Fabric one. Since it is also not uncommon for such masses to be melted several times there is a risk that the pentachlorophenol will be almost completely lost.
Erhitzt man z. B. Bitumen mit einem Gehalt von 3°/o Pentachlorphenol 5 Stunden auf 160 bis 180° C, so ist danach der Gehalt an Pentachlorphenol auf 0, 6"/o abgesunken.-Außerdem ist dieser Wirkstoff in schwachen Alkalien löslich, so daß Dichtungen, die in schwach alkalischen Böden verlegt sind, allmählich ausgelaugt werden.If you heat z. B. bitumen with a content of 3% pentachlorophenol 5 hours at 160 to 180 ° C, then the pentachlorophenol content is 0, 6 "/ o decreased. In addition, this active ingredient is soluble in weak alkalis, see above that seals installed in weakly alkaline soils gradually leached out will.
Es ist ferner bekannt, daß die Wurzelspitzen von gewissen Pflanzen, die sich in der Nähe von unterirdisch verlegten Wasserleitungen befinden, mit verwunderlicher Zielsicherheit und Beharrlichkeit dorthin streben, wo sie Wasser wittern und überwinden hierbei mit erstaunlicher Kraft Hindernisse aller Art. Selbst durch wasserdichte Muffenverbindungen schaffen sie sich Zugang zum Wasser. Leichter gelingt ihnen das bei mit den üblichen Vergußmassen abgedichteten Rohrverbindungen, obwohl diese Vergußmassen aus Bitumen und Füllstoffen, wie Kaolin, Talkum, Asbest, Sand, Stein-und Quarzmehl u. dgl., bestehen. It is also known that the tips of the roots of certain plants, that are located near underground water pipes, with astonishing Strive to get where you can smell water and overcome it with determination and perseverance here with astonishing power all kinds of obstacles. Even watertight ones Socket connections create access to the water. This is easier for them to do in the case of pipe connections sealed with the usual potting compounds, although these potting compounds made of bitumen and fillers such as kaolin, talc, asbestos, sand, stone and quartz flour and the like.
Man ist daher schon seit langem bemüht, solche Dichtungen wurzelfest zu machen. Dies war bisher jedoch nur mit beschränktem Erfolg möglich. Efforts have therefore long been made to make such seals root-proof close. So far, however, this has only been possible with limited success.
Es wurde gefunden, daß Dichtungen und Vergußmassen dadurch wurzelfest bzw. sogar wurzelabweisend gemacht werden können, daß man ihnen Veresterungsprodukte von Pentachlorphenol mit höheren Carbonsäuren oder mehrbasischen Säuren, Salze des Pentachlorphenols oder Verbindungen, in denen Pentachlorphenol über ein mehrbasisches Metallatom mit einem höhermolekularen Säurerest verbunden ist, zusetzt. It has been found that this makes seals and casting compounds root-proof or even root-repellent can be made that they are esterification products of pentachlorophenol with higher carboxylic acids or polybasic acids, salts of Pentachlorophenols or compounds in which pentachlorophenol has a polybasic Metal atom is connected to a higher molecular acid residue, adds.
Der Zusatz der genannten Stoffe zu solchen Vergußmassen bewirkt überraschenderweise, daß die Wurzeln der Pflanzen, insbesondere Baum-und Strauchwurzeln, in der Regel schon bevor sie mit den Wirkstoff enthaltenden Massen in engere Berührung kommen ihre Wachstumsrichtung in einigem Abstand von den Massen umkehren, ohne daß sie und damit die Pflanzen erkranken oder absterben. Sollten dennoch einzelne Wurzelspitzen bis zur Oberfläche der Vergußmassen oder in dieselben eindringen, so sterben sie schon in den oberen Schichten der Massen ab. The addition of the substances mentioned to such casting compounds surprisingly causes that the roots of plants, especially tree and shrub roots, usually even before they come into closer contact with the masses containing the active substance reverse their direction of growth at some distance from the masses without them and thus the plants become sick or die. Nevertheless, individual root tips should if they penetrate to the surface of the casting compound or into it, they die already in the upper strata of the masses.
Geeignete Ester des Pentachlorphenols mit höheren Carbonsäuren oder mehrbasischen Säuren sind z. B. die Ester mit Laurylsäure und mit Vorlauffettsäuren sowie das Bis-pentachlorphenyl-und das Pentachlorphenylisooctylcarbonat. Suitable esters of pentachlorophenol with higher carboxylic acids or polybasic acids are e.g. B. the esters with lauric acid and with first run fatty acids as well as bis-pentachlorophenyl and pentachlorophenyl isooctyl carbonate.
Als Vertreter der Verbindungen, in denen Pentachlorphenol über ein mehrbasisches Metallatom mit einem höhermolekularen Säurerest verbunden ist, seien z. B. das in Bitumen lösliche Pentachlorphenyl-kupfer-oder -zink-oder-bleinaphthenat genannt. As a representative of the compounds in which pentachlorophenol has a polybasic metal atom is connected to a higher molecular acid residue z. B. pentachlorophenyl copper or zinc or lead naphthenate, which is soluble in bitumen called.
Daß derartige Derivate des Pentachlorphenols wurzelabweisend wirken, ist überraschend, denn diese Verbindungen sind z. B. gegen Mikroorganismen sehr viel weniger wirksam als Pentachlorphenol, zum Teil sogar praktisch unwirksam. Gegen Pflanzenwurzeln entspricht ihre Wirksamkeit hingegen voll ihrem Pentachlorphenolgehalt. Dies zeigt die nachstehende Tabelle. That such derivatives of pentachlorophenol have a root-repellent effect, is surprising, because these compounds are z. B. against microorganisms very much much less effective than pentachlorophenol, in some cases even practically ineffective. Against Plant roots, on the other hand, fully correspond to their pentachlorophenol content. This is shown in the table below.
Die dort angegebenen Keimhemmungswerte gegenüber verschiedenen Mikroben
wurden auf einem Malzgelatine-und gegenüber verschiedenen Bakterien auf einem Pepton-Gelatinenährboden
bestimmt. Die wurzelabweisende Wirkung wurde an Lupinen nach der in der Normvorschrift
DIN 4038 beschriebenen Methode ermittelt. Die Werte für die Pentachlorphenolderivate
beziehen sich auf deren Pentachlorphenolgehalt.
