Description

Verfahren zur Behandlung klebriger Harz oberflächen Man hat bisher bei der Herstellung der Oberflächen natürlicher oder künstlicher Harze die Klebrigkeit etwa durch Pudern mit Talkum oder ähnlichen Pulvern verhindert. Die Anwendung solcher Pulver hat aber zur Folge, daß die Klebrigkeit nicht nur vorübergehend, sondern dauernd aufgehoben ist. Solche Verfahren sind daher nicht anwendbar, wenn die Klebrigkeit nur vorübergehend abgeschwächt oder aufgehoben werden soll.Process for treating sticky resin surfaces One has so far in the manufacture of the surfaces of natural or artificial resins, the stickiness prevented by powdering with talc or similar powders. The application of such But powder has the consequence that the stickiness is not only temporary, but is permanently canceled. Such methods are therefore not applicable when the stickiness should only be temporarily weakened or canceled.

Die Erfindung betrifft ein Verfahren, um Harzoberflächen, insbesondere dreidimensionale Gebilde, vorübergehend nicht klebrig zu machen. Das Verfahren besteht darin, die Oberfläche mit Substanzen zu bedecken, welche sich schon bei mäßiger Wärme verflüchtigen und dabei die Harzoberfläche wieder freigeben. Als solche Substanzen können beispielsweise feste Stoffe, wie Benzoesäure, Benzochinon oder Carbonate des Ammoniums, verwendet werden. Die Aufbringung erfolgt beispielsweise durch Pudern, Aufstäuben oder Anwendung einer Lösung der betreffenden Substanz und Auftrocknung. Die Substanz verbleibt auf der Oberfläche, solange die Klebrigkeit verhindert werden soll, und wird beispielsweise durch Anwendung von Wärme oder Dampf bei gewöhnlichem oder vermindertem Druck entfernt, wenn die Klebrigkeit zur Haftung etwa eines Textilüberzugs gebraucht wird. The invention relates to a method to resin surfaces, in particular three-dimensional structures, temporarily non-sticky. The procedure persists in covering the surface with substances which are already present in moderate The heat evaporates and the resin surface is released again. As such substances can, for example, solid substances such as benzoic acid, benzoquinone or carbonates of ammonium. The application is carried out, for example, by powdering, Dusting or application of a solution of the substance in question and drying. The substance remains on the surface as long as stickiness is prevented should, and is for example by application of heat or steam in ordinary or reduced pressure if the tackiness for adhesion such as a textile cover is needed.

Die Erfindung kann z. B. folgendermaßen ausgeführt werden. Versucht man einen Handschuh, der durch Tauchen einer Form in Latex entstanden ist, mit einem Textilhandschuh zu überziehen, so gelingt dies infolge der starken Klebrigkeit nicht ohne weiteres. Gemäß der Erfindung wird der auf der Tauchform sitzende, unvulkanisierte, aber abgetrocknete Latexhandschuh beispielsweise mit Ammoniumbicarbonat eingepudert oder in eine konzentrierte Ammoniumbicarbonatlösung eingetaucht und diese aufgetrocknet. Dann läßt sich der Textil- handschuh leicht überstreifen. Durch Anhü,,eln oder allseitigen heißen Druck o. dgl. verflüchtigt sich das Salz, und die Latexschicht wird fest mit der Textilschicht verbunden. Die Erwärmung kann zur Vulkanisation ausgenutzt werden, oder die Vulkanisation kann nachträglich erfolgen. The invention can e.g. B. be carried out as follows. Tries a glove made by dipping a mold in latex with a To put on a textile glove does not succeed due to the strong stickiness just like that. According to the invention, the unvulcanized, but dried latex gloves, for example, powdered with ammonium bicarbonate or immersed in a concentrated ammonium bicarbonate solution and dried it up. Then the textile Slightly put on glove. By The salt volatilizes by applying hot pressure on all sides or the like, and the latex layer is firmly connected to the textile layer. The warming can lead to Vulcanization can be exploited, or the vulcanization can take place afterwards.
