Definitions

  • the present invention relates to substances and preparations which protect buildings, seals and insulation against ingrowth and through-growth of roots.
  • the substances are used for the production of root-resistant building materials such as bitumen mixtures, sealants and insulating materials.
  • Root growth in building materials leads to unwanted material damage. Particularly plastic materials, such as sealing compounds, roofing membranes, but also asphalt can be destroyed by plant roots.
  • plastic materials such as sealing compounds, roofing membranes, but also asphalt can be destroyed by plant roots.
  • the penetration of roots in the seals of sewers and sewage pipes, in flat roof covers, in bitumen insulation of pipes, bridges and water structures as well as the ingrowth and ingrowth of roots on light bitumen roads are generally known problems. This can result in leaks, corrosion, damage to buildings, roads and pipelines.
  • herbicides such as, for example, 2,4-dichlorophenoxyacetic acid, 2,4,5-trichlorophenoxyacetic acid and ⁇ -naphthylacetic acid or their salts, amides or esters, for example isooctyl ester or esters of l-hydroxy-2-butoxyethane, furthermore phenyl- N-isopropyl carbaminate and p-chlorophenyldimethylurea can be used as root inhibitors (DE 1 108 833).
  • phenoxycarbon acids as herbicides has long been known (see, eg, The Agrochemicals Handbook, 3 r d Ed, Royal Soc Chem., Cambridge 1993).
  • Building materials include to understand bituminous building materials as well as concrete or building materials containing concrete, as well as those that e.g. be described in WO 92/10 537.
  • the application therefore relates to the use of phenoxycarboxylic acid bonded to an inorganic support material for protecting buildings, insulation and seals against root penetration.
  • R 1 to R 5 independently of one another represent F_-Br, CI, F, CF3, CF2H, methyl, ethyl, propyl, methoxy, OCF3 and R 6 stands for H, Me, Et
  • Preferred compounds of the formula (I) are those in which R 1 represents Me, CI, CF 3 , R 2 to R 5 represent H, CI, F, methyl, CF 3 and R 6 represents H, Me.
  • R 2 , R 4 , R 5 stand for H, R 3 is CI and R 6 is Me.
  • Suitable support materials include: e.g. nat. and synthetic zeolites, layered silicates, clays, precipitated silicas, diatomaceous earth, silica gels, aerosils, bentonites, kaolins, activated carbons, natural and synthetic clay minerals, TiO 2, ZnO, calcium carbonate, dolomites, pumice stones, attapulgites, sepiolites, ball clays, clays, as well as aluminophosphates , Metal aluminophosphates and crystalline silicas with pore structure.
  • zeolites or molecular sieves which come under the following formula, have proven to be particularly suitable support materials:
  • M is an exchangeable cation
  • E ⁇ means a trivalent element
  • E 2 is a tetravalent element, E ⁇ and E 2 being the anionic skeleton,
  • n / m is the ratio of the elements E ⁇ and E 2 and can have values of 1 to 3,000, preferably 1 to 2,000,
  • the zeolites having pore sizes of at least 4 ⁇ , for example pore sizes in the range from 4 to 8 ⁇ , preferably in the range 5 to 8 ⁇ .
  • the basic structure is made of zeolites from a network of SiO-4 and AIO4
  • Tetrahedron constructed, whereby the individual tetrahedra are linked with each other by oxygen bridges via their corners and form a spatial network that is moderately crisscrossed by channels and cavities.
  • the aluminum as a representative of the element E * can be partially replaced by other trivalent or divalent elements such as B, Ga, In, Fe, Cr, V, As, Sb or Be, Cu and Co.
  • the silicon as a representative of the element E 2 can be replaced by other tetravalent elements, such as Ge. Interchangeable cations are stored to compensate for the negative charge of the lattice caused by the trivalent elements.
  • the individual zeolite structures (types) also differ in the arrangement and size of the channels and cavities.
  • Zeolites always contain q H 2 O as a sorbed water phase, which can be removed reversibly without the structure losing its structure.
  • a detailed description of zeolites can be found, for example, in the monograph "Introduction to Zeolite Science and Practice” Ed. H. van Bekkum, EM Flanigen, JC Jansen in the series Studies in Surface Science and Catalysis, Vol. 58, Elsevier, Amsterdam, Oxford, New York, Tokyo, 1991.
  • aluminophosphates such as e.g. A1PO-5, A1PO-11, AJPO-8, A1PO-17 and silicoaluminophosphates such as e.g. S.APO-5, SAPO-11, SAPO-34, SAPO 17 and others.
  • layered silicates such as e.g. Magadiit or SKS-6 suitable as a carrier material.
  • zeolites Preferred among the zeolites are the easily accessible zeolite structures such as zeolite A and faujasite with the types zeolite X and zeolite Y and the following formulas: Type A Na 12 [(AlO 2 ) ⁇ 2 • (SiO 2 ) ⁇ ] • 2 ? H 2 0
  • Type X Na 86 [AlO 2 ) 86 • (SiO 2 ) 106 ] • 2 64 H 2 O
  • the various ion-exchanged forms are also suitable as a carrier material.
  • the carriers are loaded with the phenoxycarboxylic acids in different ways adapted to the respective carrier material. Such techniques would e.g. described in DE 1 219 008.
  • the loading of molecular sieves or zeolites e.g. in that the molecular sieve is first freed of water by heating, which e.g. can be done by heating to 400 to 450 ° C for several hours, and then brought into contact with the active substance.
  • Loading takes place in any way, e.g. by passing the active substance brought into the vapor form through the zeolite or by immersing the zeolite in the liquid or molten active substance or a solution of the active substance in a non-polar, volatile solvent with subsequent evaporation of the solvent.
  • the amount of active substance with which the carrier material is loaded can vary within wide limits. It depends on the active ingredient used and the conditions under which the carrier / active ingredient combination is to be used.
  • amounts of from 0.1 to about 90% by weight of active compound, preferably 5 to 70%, particularly preferably 10 to 50%, based on the carrier material, are applied.
  • the maximum loading is preferably selected in order to achieve a high active ingredient concentration per mass of starting material.
  • the phenoxycarboxylic acid is preferably mixed in its crystalline form with the carrier material and together to a temperature above its melting point warmed up.
  • the carrier material water, oxygen, air etc. may have to be excluded.
  • auxiliaries can also be added to the mixture of carrier material and phenoxycarboxylic acid, e.g. reduce dusting of the mixture or sensitivity to water.
  • phenoxycarboxylic acid / carrier combinations are used directly or in the form of other preparations such as e.g. mixed with bitumen, tar pitch, building materials or insulating materials. It is also possible to separate the carrier material and the phenoxycarboxylic acid separately but at the same time to add it to the building materials.
  • the content of phenoxycarboxylic acid in the bitumen is 0.01 to 20% by weight, preferably 0.1 to 5%, particularly preferably 0.3 to 2%.
  • the content of phenoxycarboxylic acid in bituminous building * _ ⁇ n results from the application concentration of the acid in the bitumen and the bitumen content in the building materials. It is generally 0.05 to 0.5%.
  • the fixed phenoxycarboxylic acid can also be added to these and worked in together with them.
  • Example 2 Analogously to Example 1, only with H zeolite Y, a dealuminated zeolite Y with an SiO 2 / Al 2 ⁇ 3 ratio of 90.
