Abstract

The process for producing a ready-to-use mixture of reactive plastics, such as, for example, epoxy, methacrylate or polyester resins and, if appropriate, fillers and additives, provides for the synthetic resin components to be cooled before, during or directly after mixing to the extent that they no longer react with one another. The mixture is then kept in the cooled state until use. The process is suitable in particular for preparing ready-to-use mixtures of reactive plastics in the building industry.

Description

Verfahren zur Herstellung einer gebrauchs- Process for the production of a usable

fertigen Mischung von Reaktionskunststoffen Die Erfindung betrifft ein Verfahren zur Herstellung einer gebrauchsfertigen Mischung von Reaktionskunststoffen, wie zQB Epoxyd- t Methacrylat- oder Polyesterharzen und ggf. finished mixture of reaction plastics The invention relates to a process for the production of a ready-to-use mixture of reaction plastics, such as epoxy t methacrylate or polyester resins and possibly

Füll- und Zuschlagstoffen.Fillers and aggregates.

Mehrkomponenten-Mischungen von Reaktionskunststoffen finden insbesondere im Baubereich, Bausanierungsbereich und Bautenschutz vielfältige Anwendung. Nur beispielhaft seien für den niederviskosen Bereich die für die Rißsanierung verwendeten Gießharze und für den hochviskoan Bereich die verschiedene Füllstoffe enthaltenden Kunststoffmörtel genannt. Üblicherweise werden die Kunstharzkomponenten getrennt gelagert und erst unmittelbar vor Gebrauch zusammengebracht und bei Umgebungstemperatur gemischt. Die dabei einsetzende Reaktion findet je nach den von Fall zu Fall schwankenden Zustandsbedingungen unterschiedlich schnell, gelegentlich auch zu schnell statt Die Mischung vor Ort setzt daher ein hohes Maß an Erfahrung und Zuverlässigkeit voraus und ist auch dann noch mit einem erheblichen Risiko und Zeitaufwand verbundes Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, beì welchem sich besser als bisher die Einhaltung bestimmter Bedingungen in der Praxis und die homogene Mischung der Komponenten gewährleisten lassen, und diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kunstharzkomponenten vor, während oder unmittelbar nach dem Mischen soweit abgekühlt werden, daß sie nicht miteinander reagieren, und bis zum Gebrauch im gekühlten Zustand gehalten werden.In particular, multicomponent mixtures of reaction plastics are found Diverse applications in the construction sector, building renovation and building protection. Just Examples are those used for the repair of cracks in the low-viscosity area Casting resins and, for the highly viscous area, the various fillers Called plastic mortar. Usually the synthetic resin components are separated stored and only brought together immediately before use and at ambient temperature mixed. The reaction that sets in takes place depending on which varies from case to case State conditions vary quickly, sometimes too quickly The mix on site therefore requires a high level of experience and reliability ahead and is still associated with a considerable risk and time investment The invention is based on the object of providing a method of the type mentioned at the beginning to create whichever is better than before the observance of certain Ensure practical conditions and a homogeneous mixture of the components let, and this object is achieved according to the invention in that the synthetic resin components before, during or immediately after the mixing are cooled down to such an extent that they do not react with each other, and are kept refrigerated until use will.

Die Erfindung bietet die Möglichkeit, die aufwendigen Milch vorgänge unter kontrollierten Bedingungen im Betrieb durchzuführen. Weil dort mit großer Zuverlässigkeit sehr homogene Mischungen der Kunstharzkomponenten und der Füll- und Zuschlagstoffe hergestellt werden können, kann im Einzelfall der Kunstharzanteil verringert werden. Auf diese Weise lassen sich die Herstellungskosten senken. Außerdem wird die oft witterungsabhäng-ge Tätigkeit auf der Baustelle abgekürzt.The invention offers the possibility of consuming milk operations to be carried out under controlled conditions in the company. Because there with great Reliability very homogeneous mixtures of synthetic resin components and filling and aggregates can be produced, the synthetic resin content can be used in individual cases be reduced. In this way, the manufacturing costs can be reduced. aside from that the often weather-dependent activity on the construction site is shortened.

Um das erfindungsgemäße Ziel zu erreichen, bedarf es in vielen Fällen nicht einmal sehr tiefer Temperaturen. Bei Epoxydharzen und Polyesterharzen können z.B. schon Temperaturen von ungefähr 0 °C oder wenige Grad unter dem Gefrierpunkt ausreichen. Die Temperaturen, bei denen die Komponenten der verschiedenen Reaktionskunststoffe nicht mehr vernetzen, sind dem Fachmann bekannt. Je nach Mischverhalten können die Kunstharzkomponenten vor, während oder unmittelbar nach dem Mischvorgang auf eine Temperatur abgekühlt werden, bei welcher die Reaktion blockiert ist. Dabei besteht auch die Möglichkeit, im gekühlten Zustand harte Materialien zu mahlen und im gemahlenen Zustand zu mischen.In many cases, it is necessary to achieve the aim of the invention not even very cold temperatures. In the case of epoxy resins and polyester resins, you can E.g. temperatures of around 0 ° C or a few degrees below freezing point sufficient. The temperatures at which the components of the various reaction plastics no longer crosslink, are known to the person skilled in the art. Depending on the mixing behavior, the Synthetic resin components before, during or immediately after the mixing process on a Temperature at which the reaction is blocked. There is also the possibility of grinding hard materials in the cooled state and in the ground Mix condition.

Es versteht sich, daß die vorgefertigten, gekühlt gelagerten Mischungen auch während des Transports und der vorübergehenden Aufbewahrung auf der Baustelle in geeigneten Gefäßen gekühlt gehalten werden müssen. Vor Ort brauchen sie dann aber lediglich entnommen zu werden und können direkt zur Anwendung kommen, wobei die Erwärmung auf Umgebungstemperatur je nach den Umständen und der Masse mittels Heizeinrichtungen oder auch ohne besondere Maßnahmen erfolgen kann. Niederviskose Reaktionskunststoffe werden dann mit den bekannten Geräten z.B. für die Rißsanierung verarbeitet, während mittelviskose Systeme z.B. ähnlich wie Knetmassen in Folien verschweißt und z.BX im Dünnbettverfahren für Beschichtungszwecke verwendet werden können Hochviskose wsteme finden beispielsweise bei der Betonsanierung als Auffüllmasse Anwendung In der Praxis entnimmt der Anwender in einfacher Weise dem Kühlbehältnis eine mit Folie umschlossene Packung der vorgefertigten, gekühlten Mischung, entfernt die Verpackungsfolie und drückt die Masse in den auszufüllenden Hohlraum. Nach bekannter Technik wird dann die Oberfläche der vorbestimmten Geometrie angepaßt.It goes without saying that the prefabricated, refrigerated stored mixtures also during transport and temporary storage on the construction site must be kept refrigerated in suitable containers. You then need them on site but only to be removed and can be used directly come with heating to ambient temperature depending on the circumstances and the Mass can be done by means of heating devices or without special measures. Low-viscosity reaction plastics are then used with the known devices, e.g. for the crack repair processes, while medium-viscosity systems e.g. similar to kneading masses welded in foils and e.g. used in the thin bed process for coating purposes Highly viscous wsteme can be found, for example, when renovating concrete Filling compound Application In practice, the user can easily remove the Cooling container a foil-enclosed pack of the prefabricated, cooled Mixture, removes the packaging film and presses the mass into the filler Cavity. According to known technology, the surface is then of the predetermined geometry customized.

Schließlich eignet sich die Erfindung auch für die Beschichtung z.B, von Betonflächen mit Reaktionskunststoffbahnen.Finally, the invention is also suitable for coating e.g. of concrete surfaces with reaction plastic sheets.

Diese können nach Art von Tapeten mit oder ohne Trägerbahnen vorgefertigt, durch Kühlung in der Reaktion blockiert und im zusammengerollten Zustand aufbewahrt werden. Auf der Baustelle brauchen sie dann nur noch aufgewärmt und auf die zu bekleidenden Betonflächen aufgelegt zu werden.These can be prefabricated in the manner of wallpaper with or without carrier strips, blocked in the reaction by cooling and stored in a rolled-up state will. On the construction site, they then only need to be warmed up and put on the clothes to be worn Concrete surfaces to be laid.

Die Auswahl der für eine bestimmte Anwendung geeigneten Kunstharze richtet sich auch bei dem neuen Verfahren im wesentlichen nach denselben Kriterien wie bisher bei Herstellung der gebrauchsfertigen Mischung vor Ort. Es kommen auch grundsätzlich dieselben Materialien in Frage so daß sich eine vollständige Aufzählung erübrigt. Auf jeden Fall ist die Erfindung nicht auf die nur beispielhaft genannten Kunstharzsysteme beschränkt, sondern zielt unabhängig vom Material auf die beschriebene Vorfertigung und Zwischenlagerung der Mischung im durch Kühlung geblockten Zustand.The selection of the most suitable synthetic resins for a particular application is based essentially on the same criteria for the new procedure as before with the production of the ready-to-use mixture on site. There are also coming basically the same materials in question so that is a complete list unnecessary. In any case, the invention is not limited to those mentioned only by way of example Resin systems limited, but aims at the described regardless of the material Prefabrication and intermediate storage of the mixture in the blocked state by cooling.
