Beschreibung der ErfindungDescription of the invention Filmbildende Überzüge, Verklebungen und/oder Dichtungen auf der Grundlage von wäßrigen Dispersonen und/oder Emulsionen von Kunststoffen und/oder Naturharzen lassen in bezug ihrer Haftfestigkeit, Härte, Flexibilität, Wasser- und Wetterbeständigkeit im allgemeinen zu wünschen übrig, so daß ihr Einsatzgebiet, d. h. ihre praktische Verwendbarkeit, beschränkt ist. Insbesondere weisen sie bei Verwendung als Anstrichmittel bzw. Kunststoffbeschichtungen auf Natur- und Kunststeinen, Ziegern, Klinkern, Fliesen, Tesr-, Asphalt-, Bitumen-, Zement- und Kunststoffböden, bzw. Putzuntergründen, Nachteile auf, die in ihrer Natur und Struktur rohstoffbedingt sind. Sie sind zu weich, ihr Haftvermögen — insbesondete auf porendichten Untergründen — ist mangelthaft und ihr starkes Wasseraufnahme- und damit -Quellvermögen birgt auch im aufgetrockneten Zustand die Gefahr des Auffrierens bei Temperaturen unter — 0° C in sich.Film-forming coatings, bonds and / or seals based on aqueous dispersions and / or emulsions of plastics and / or natural resins with regard to their adhesive strength, Hardness, flexibility, water and weather resistance generally leave something to be desired, so that their area of application, d. H. their practical usability, is limited. In particular, they exhibit when used as paints or plastic coatings on natural and artificial stone, brick, clinker, tiles, Tesr, asphalt, bitumen, cement and synthetic floors, or plaster substrates, have disadvantages that are due to the nature and structure of the raw material are. They are too soft, their adhesive strength - especially on pore-tight surfaces - is inadequate and their strong water absorption and thus swelling capacity also conceals in the dried up Condition there is a risk of freezing at temperatures below - 0 ° C. Dieselben Nachteile sind auch bei ihrer Verwendung als Verklebungs- und/oder Dichtungsmittel gegeben, woteiWIkeihe Rolle spielt, ob diese wäßrigea Dispersio'iia^nd)ioder Emulsionen von Kunststoffen und/odeäiÖMi^arzen mit Pigmenten und/oder Füllstoffen versetztlunÜ oder nicht.The same disadvantages are also associated with their use as adhesives and / or sealants given what role it plays whether this wateryea Dispersio'iia ^ nd) i or emulsions of plastics and / odeäiÖMi ^ arzen with pigments and / or Fillers added or not. Eingehende Versuche haben ergeben, daß diese Nachteile ausgeräumt werden, wenn man dieee Dispersionen und/oder Emulsionen vor ihrer Vi /beitung ein feuchtigkeitshärtendes Polyurethane· bzw. Polyurethansystem unter intensivem Umrühren manuell oder maschinell untermischtIn-depth tests have shown that these disadvantages are eliminated if the dispersions are used and / or emulsions before their processing a moisture-curing polyurethane or polyurethane system with intensive stirring mixed in manually or by machine Durch dieses Verfahren tritt eine chemische Reak- Itidto.'- ;^ws|pbc4)djiip feuchtigkeitshärtenderi Polyurethanharz bzw. Polyurethansystem und der wäßrigen Dispersion und/oder Emulsion ein, die dem Endprodukt eine bedeutend bessere Haftfähigkeit, Härte, Flexibilität und Wetterbeständigkeit verleihen und damit wäßrigen Dispersionen und/oder Emulsionen ein Einsatz- und Verarbeitungsgebiet eröffnen, das — rohstoffbedingt — bisher unvorstellbar war.Through this process, a chemical reaction occurs Itidto .'- ; ^ ws | pbc4) djiip moisture-curing polyurethane resin or polyurethane system and the aqueous dispersion and / or emulsion, which give the end product significantly better adhesion, hardness, flexibility and weather resistance and thus Aqueous dispersions and / or emulsions open up a field of application and processing which - due to the raw materials used - was previously unimaginable. Das Untermischen von feuchtigkeitshärtenden Polyurethanharzen bzw. Polyurethansystemen in wäßrige Dispersionen und/oder Emulsionen erweist sich somit als ein ausgezeichnetes Verfahren und stellt einen bedeutenden Fortschritt dar.Mixing in moisture-curing polyurethane resins or polyurethane systems in Aqueous dispersions and / or emulsions thus proves to be an excellent process and represents a significant advance.
