Description

       

  Wurzelfeste bzw. wurzelabweisende     bitumenhaltige    Dichtung und     Vergussmasse       Die     Wurzelspitzen    von gewissen Pflanzen, die  sich in der Nähe von z.     JB.    unterirdisch verlegten  Wasserleitungen befinden, streben     bekanntlich    mit  verwunderlicher Zielsicherheit und     Beharrlichkeit          dorthin,    wo sie Wasser wittern, und     überwinden     hierbei     mit        erstaunlicher        Kraft        Hindernisse    aller Art.

    Selbst durch wasserdichte     Muffenverbindungen    schaf  fen sie sich Zugang zum Wasser. Leichter     gelingt     ihnen das bei     mit    den     üblichen        Vergussmassen    abge  dichteten Rohrverbindungen, obwohl diese     Verguss-          massen    aus Bitumen und Füllstoffen,. wie     Kaolin,          Talkum,    Asbest,     Sand,    Stein- und Quarzmehl und  dergleichen, bestehen.  



       Man.    ist daher schon seit langem bemüht, solche  Dichtungen     wurzelfest    zu machen. Dies war bisher  jedoch nur mit beschränktem Erfolg möglich.  



  Es wurde nun gefunden, dass bituminöse Dich  tungen und     Vergussmassen    der erwähnten Art einen  guten Schutz gegen das     Einwachsen    von     Wurzeln.     bieten, das heisst, dass sie     wurzelfest    bzw.

   sogar weit  gehend wurzelabweisend sind, wenn sie mit Bitumen  und Asphaltmassen     verträgliche,    in Wasser     nicht     merklich lösliche, schwerflüchtige     Herbizide,    wie       Schwermetallsalze    von     Polychlorphenolen,    insbeson  dere von     Pentachlorphenol,

      oder     Veresterungs-          produkte    solcher     Phenole    mit höheren     Carbonsäuren     oder mehrbasischen Säuren sowie die     Verbindungen     von mehrwertigen Metallen mit     Polychlorphenolen     einerseits und höheren     Carbonsäuren    anderseits,  ferner Herbizide, wie     2,4-Dichlorphenoxyessigsäure,          2,4,5-Trichlorphenoxyessigsäure    und     a-Naphthyl-          essigsäure    sowie deren Salze, Ester und     Amide,

       ferner     Phenyl-N-isopropylcarbaminat    und     p-Chlor-          phenyldimethylharnstoff,    enthalten.  



  Geeignete Verbindungen im Sinne dieser Erfin  dung sind z. B.    Zink- bzw.     Kupferpentachlorphenolat,          Pentachlorphenyl-laurinsäureester,          Bis-pentachlorphenylcarbonat,          Pentachlorphenylisooctylcarbonat,          Pentachlorphenyl-zink-naphthenat,          2,4-Dichlorphenoxyessigsäurebutylester,          2,4,5-Trichlorphenoxyessigsäurebutylglykolester,          2,4,5-Trichlorphenoxyessigsäure-N-methylamid     und       2,4-Dichlorphenoxyessigsäureamid.       Die genannten Herbizide haben eine über  raschend starke Wirkung,

   so     dass        ein    guter Schutz  im     allgemeinen    schon mit geringen Mengen erzielt  wird.     In    manchen     Fällen    genügen schon Zusätze  zwischen etwa 0,1 und etwa     0,30/a,    jedoch können  auch grössere Mengen, so z. B. bis zu etwa 5     0/a,     der     erwähnten    Herbizide den     Vergussmassen    zuge  setzt     werden.     



  Der Zusatz der     genannten        Stoffe    zu solchen     Ver-          gussmassen    bewirkt überraschenderweise, dass die       Wurzeln    der     Pflanzen,    insbesondere Baum- und       Strauchwurzeln,    in der Regel schon bevor sie mit  den Wirkstoff enthaltenden Massen in engere Be  rührung kommen, ihre Wachstumsrichtung in eini  gem Abstand von den Massen umkehren, ohne dass  sie und damit die     Pflanzen    erkranken oder abster  ben.

   Sollten     dennoch        einzelne    Wurzelspitzen bis       zur    Oberfläche der     Vergussmassen    oder in dieselben  eindringen, so sterben sie schon in den obern  Schichten der Massen ab.  



  Die     Dichtungen    und     Vergussmassen    gemäss der       Erfindung    können für die verschiedensten Zwecke  verwendet werden, so ausser bei den bereits erwähn  ten unterirdisch verlegten Wasserleitungen auch bei  Leitungen     beliebiger    Art oder bei mit dem Erd  reich in Berührung stehenden oder in die Erde ein-      gelassenem Mauerwerk, bei Strassenbelägen und der  gleichen.  



  <I>Beispiel 1</I>       Vergussmassen        mit    2,5      /u        Zinkpentachlorphenolat     sind gegen das Einwachsen von Wurzeln voll wirk  sam und verlieren auch bei wiederholtem Erhitzen  praktisch nicht an Wirksamkeit.  



  <I>Beispiel 2</I>  Eine     Asphalt-Dichtungsmasse    mit     0,60/a    Zusatz  an     2,4-Dichlorphenoxyessigsäurebutylester    ist gegen       Wurzeleinwachsen    voll wirksam.  



  <I>Beispiel 3</I>  Bituminöse Dichtungsmassen mit einem Gehalt  von     0,7 /a        an        2,4,5-Trichlorphenoxyessigsäurebutyl-          glykolester    sind gegen das Einwachsen von Wurzeln  <B>a</B>  schützt, auch wenn die Massen vorher mehrfach  auf 160-180  C erhitzt     wurden.  



  Root-resistant or root-repellent bituminous sealant and potting compound. The root tips of certain plants that are near z. JB. underground water pipes are known to strive with astonishing accuracy and perseverance where they smell water, and overcome obstacles of all kinds with astonishing power.

    They even gain access to the water through watertight socket connections. This is easier for them to do with pipe connections sealed with the usual potting compounds, although these potting compounds are made from bitumen and fillers. such as kaolin, talc, asbestos, sand, rock and quartz flour and the like.



       Man. has therefore tried for a long time to make such seals root-proof. However, this has so far only been possible with limited success.



  It has now been found that bituminous seals and casting compounds of the type mentioned provide good protection against the ingrowth of roots. offer, that means that they are root-proof or

   are even largely root-repellent if they are compatible with bitumen and asphalt compounds, not noticeably soluble in water, low-volatility herbicides, such as heavy metal salts of polychlorophenols, in particular of pentachlorophenol,

      or esterification products of such phenols with higher carboxylic acids or polybasic acids as well as the compounds of polyvalent metals with polychlorophenols on the one hand and higher carboxylic acids on the other hand, also herbicides such as 2,4-dichlorophenoxyacetic acid, 2,4,5-trichlorophenoxyacetic acid and a-naphthylacetic acid as well their salts, esters and amides,

       also contain phenyl-N-isopropylcarbaminate and p-chlorophenyldimethylurea.



  Suitable compounds for the purposes of this inven tion are, for. B. zinc or copper pentachlorophenolate, pentachlorophenyl lauric acid ester, bis-pentachlorophenyl carbonate, pentachlorophenyl isooctyl carbonate, pentachlorophenyl zinc naphthenate, 2,4-dichlorophenoxyacetate, 2,4,5-trichlorophenoxyacetate, 2,4,5-trichlorophenoxyacetate butylglycol ester, 2,4,5-trichlorophenoxyacetate and trichloro-2,4-phenoxyacetamido-butylglycol ester, 2,4,5-phenoxyacetate 2,4-dichlorophenoxyacetic acid amide. The herbicides mentioned have a surprisingly powerful effect,

   so that good protection is generally achieved even with small amounts. In some cases, additions between about 0.1 and about 0.30 / a are sufficient, but larger amounts can also be used, e.g. B. up to about 5 0 / a, the herbicides mentioned are added to the casting compounds.



  The addition of the substances mentioned to such potting compounds surprisingly has the effect that the roots of the plants, in particular tree and bush roots, usually before they come into closer contact with the compounds containing the active substance, their direction of growth at some distance from the Reversing masses without them and thus the plants becoming sick or dying.

   Should individual root tips nevertheless penetrate to the surface of the casting compound or into the same, then they will die in the upper layers of the compound.



  The seals and potting compounds according to the invention can be used for a wide variety of purposes, except in the case of the already mentioned underground water pipes and pipes of any kind or in the case of masonry that is in contact with the earth or sunk into the earth, in the case of road surfaces and the same.



  <I> Example 1 </I> casting compounds with 2.5 / u zinc pentachlorophenolate are fully effective against the ingrowth of roots and practically do not lose their effectiveness even with repeated heating.



  <I> Example 2 </I> An asphalt sealing compound with 0.60 / a addition of butyl 2,4-dichlorophenoxyacetate is fully effective against root ingrowth.



  <I> Example 3 </I> Bituminous sealing compounds with a content of 0.7 / a of 2,4,5-trichlorophenoxyacetic acid butyl glycol ester are protected against the ingrowth of roots <B> a </B>, even if the compounds were previously heated to 160-180 C several times.
