Description
Die Erfindung betrifft ein Mittel zur Beschichtung von Glasfasern, wie Glasseidenspinnfäden, Glasstapelfasern, Glasseidengewebe, Glasfasermatten oder Mineralwolle, wie sie in der Glas-, Baustoff- und Kunststoffindustrie Anwendung finden.The invention relates to an agent for coating glass fibers, such as glass fiber spun threads, glass staple fibers, glass silk fabrics, Glass fiber mats or mineral wool as used in glass, building materials and plastics industry find application.
Glasfasern werden üblicherweise unmittelbar nach dem Ziehen zum Schutz vor mechanischen Beanspruchungen, wie Abrieb oder Bruch, und zur Verbesserung der Gleiteigenschaften sowie der oberflächen chemischen Verträglichkeit gegenüber verschiedensten Verbundwerk stoffkomponenten mit Überzügen versehen.Glass fibers usually become immediately after pulling Protection against mechanical stress, such as abrasion or breakage and to improve the sliding properties and the surfaces chemical compatibility with various composite structures cover the fabric components.
Gebräuchlich sind hierzu Silanhaftmittel oder Chrom-Methacrylat- Komplexsalze, die sogenannten Chromschlichten, die inform von verdünnten Lösungen in Isopropanol oder wäßrigem Ammoniak ins besondere zur Herstellung von Kunststofflaminaten auf der Basis von ungesättigten Polyesterharzen, Epoxidharzen, Phenolharzen und Acrylharzen angewendet werden. Diese Hilfsmittel beeinflussen zwar die unmittelbare Verarbeitbarkeit der Glasfasern, bieten jedoch keinen längerfristigen Schutz der Fasern gegenüber aggressiven Medien.Silane adhesives or chrome methacrylate Complex salts, the so-called chrome coatings, which inform about dilute solutions in isopropanol or aqueous ammonia especially for the production of plastic laminates on the basis of unsaturated polyester resins, epoxy resins, phenolic resins and Acrylic resins can be applied. These tools do influence the immediate processability of the glass fibers, however, offer no long-term protection of the fibers against aggressive Media.
In der Erfindungsschrift SU 5 95 351 wird auch eine Schutzschicht, bestehend aus einem Methacrylatcopolymer, Epoxid-Dian-Harz, Hydro chinon und Dimethylanilin, beschrieben, die jedoch die Verwendung von organischen Lösungsmitteln erfordert und somit für den Glas seidenspinnprozeß ungeeignet ist.In SU 5 95 351, a protective layer, consisting of a methacrylate copolymer, epoxy dian resin, hydro quinone and dimethylaniline, but described the use of organic solvents and therefore for glass silk spinning process is unsuitable.
Der Erfindung liegt die Aufgabe zugrunde, durch eine neues Mittel zur Beschichtung von Glasfasern, deren Widerstandsfähigkeit gegen über aggressiven Medien, insbesondere deren Säurebeständigkeit, zu verbessern. The invention has for its object by a new means for coating glass fibers, their resistance to aggressive media, especially their acid resistance improve.
Die Aufgabe wird erfindungsgemäß durch ein Mittel gelöst, das aus einer Proteinlösung (Casein, Gelatine) und 1 bis 80 Ma.-%, bezogen auf den Feststoffgehalt des Proteins, eines Härtungsmittels be steht. Der Proteingehalt der Lösung beträgt dabei 2 bis 25 Ma.-%.According to the invention, the object is achieved by a means which consists of a protein solution (casein, gelatin) and 1 to 80% by mass on the solids content of the protein, a hardening agent stands. The protein content of the solution is 2 to 25 mass%.
Als Härtungsmittel eignen sich aliphatische Aldehyde (zum Beispiel Form-, Acet-, Propion-, Butyraldehyd) und aromatische Aldehyde wie Benz-, o- und p-Hydroxyanisaldehyd.Aliphatic aldehydes (for example Form, acet, propione, butyraldehyde) and aromatic aldehydes such as Benz-, o- and p-hydroxyanisaldehyde.
Als weitere Härtungsmittel sind Cyanursäurechlorid und Chromat ionen liefernde Verbindungen wie Ammoniumdichromat einsetzbar.Cyanuric acid chloride and chromate are further curing agents ion-providing compounds such as ammonium dichromate can be used.
Durch diese erfindungsgemäße Kombination von Proteinen, die bisher zur Beschichtung von anorganischen-nichtmetallischen Fasern keine Anwendung fanden, und Härtungsmitteln wird eine chemische Modifi zierung der Proteinkomponente erreicht, die gravierende Eigen schaftsänderungen zur Folge hat. Diese gehärteten Proteine bilden auf den Glasfasern festhaftende, mechanischen Beanspruchungen standhaltende Schutzschichten, die sich durch eine hohe chemische Stabilität gegenüber dem Angriff aggressiver chemischer Medien auszeichnen.Through this combination of proteins according to the invention, which so far none for coating inorganic-non-metallic fibers Chemical modifi Decoration of the protein component achieved the grave own changes in society. Form these hardened proteins mechanical loads adhering to the glass fibers resistant protective layers, which are characterized by a high chemical Stability against attack by aggressive chemical media award.
Die Erfindung wird anhand der nachstehenden Beispiele noch näher erläutert.The invention is further illustrated by the examples below explained.
800 g Casein, 76 g Borax und 0,2 g E 20 (Natrium-Alkansulfonat mittlerer Kohlenstoff-Kettenlänge, Hersteller Leuna-Werke) werden mit 2120 g Wasser gemischt und 4,5 Stunden bei 50 bis 60°C ge rührt. Nach dem Abkühlen ist diese Lösung verwendbar und durch die Zugabe von 6,0 g Phenol über Wochen lagerfähig.800 g casein, 76 g borax and 0.2 g E 20 (sodium alkanesulfonate medium carbon chain length, manufacturer Leuna-Werke) mixed with 2120 g of water and ge for 4.5 hours at 50 to 60 ° C. stirs. After cooling, this solution is usable and by the 6.0 g of phenol can be stored for weeks.
- a) E-Glasseiden-Spinnfäden werden mit dieser Caseingrundlösung (Feststoffgehalt 7,0 Ma.-%) beschichtet und anschließend zwei Stunden bei 130°C getrocknet.a) E-glass silk spun threads with this basic case solution (Solids content 7.0 mass%) coated and then two Dried at 130 ° C for hours.
- b) 10 Teilen der Caseingrundlösung wird 1 Teil einer 3-%igen Ammoniumdichromat-Lösung zugefügt. Mit dieser Lösung werden dann die E-Glasseiden-Spinnfäden beschichtet und anschließend bei 130°C getrocknet.b) 10 parts of the basic case solution becomes 1 part of a 3% solution Ammonium dichromate solution added. With this solution then coated the E-glass silk filaments and then dried at 130 ° C.
- c) Der Caseingrundlösung werden unter Rühren 3 Ma.-% Propion aldehyd zugegeben. Die E-Glasseiden-Spinnfäden werden mit die ser Lösung beschichtet und danach bei 130°C getrocknet.c) The casein basic solution with stirring 3 Ma .-% propion aldehyde added. The E-glass silk spun threads are with the coated water solution and then dried at 130 ° C.
Zur Stabilitätstestung werden jeweils 20 m dieser beschichteten Glasseiden-Spinnfäden für 10 Wochen bei Raumtemperatur der Einwir kung von 200 ml 2,5-%iger H2SO4 ausgesetzt und anschließend die aus dem Glas herausgelöste Al3+-Ionenkonzentration atomabsorptionsspek troskopisch gemessen.For stability testing, 20 m of these coated glass silk spun threads are exposed for 10 weeks at room temperature to the action of 200 ml of 2.5% H 2 SO 4 and then the Al 3+ ion concentration released from the glass is measured by atomic absorption spectroscopy.
Während aus der unbeschichteten E-Glasfaser unter diesen Bedingun gen 3,15 mg Al3+-Ionen/ml 2,5-%iger H2SO4 herausgelöst werden, sind es bei den mit dem gehärteten Casein beschichteten Glasfasern nur noch 1,54 mg Al3+-Ionen/ml 2,5-%iger H2SO4.While 3.15 mg Al 3+ ions / ml 2.5% H 2 SO 4 are dissolved out of the uncoated E-glass fiber under these conditions, it is only 1.54 for the glass fibers coated with the hardened casein mg Al 3+ ions / ml 2.5% H 2 SO 4 .
