Description

Verfahren zum Verkleben von Kunststoffteilen aus Polyacryl- bzw. Polymethacrylderivaten Zwecks Vereinfachung der Herstellung von Fo@rmteiZ@en besonders komplii Art werden diese vielfach aus einzelnen Teilen einfacherer Raumformen zus:ammengehaut. Auch Formteile aus Kunststoff lassend .sich auf diese Weise herstellen, wenn man die einzelnen Teile miteinander verklebt. Nun ist aber bei dien verschiedenen Kunsitstoffen das Verkleben nicht so ohne weiteres durchführbar. So z. B. bereitet das @einwandfreie Verklebten der Kuans@tsitoffe aus Polyacryl- bzw. Polym@ethacrylderivaten, stets ;große Schis ierigkeiten, wenn man als Klebstoff die bisher für diesen Zweck vorgesehenen Läsumgsmttel benutzt: Diese bisher verwendeten Lösungsmittel haben bekanntlich den Nachteil, daß sie zwischen den Klehefugen, insbesondere wenn diese etwas breiter ausfallen, nicht völlig verdunsten. Auf diese Weise hergestellte Klebefugen sied also nicht auf ihrer ganzen Fläche gleichmäßig gut und befriedigen einerseits mechanisch acht und andererseits vor allem auch in elektrischer Hinsicht nicht wegen ihrer miangelhaften ielektrIschen Festigkeit.Process for gluing plastic parts made from polyacrylic or polymethacrylic derivatives In order to simplify the production of shapes, be particularly complex these are often hewn together from individual parts of simpler spatial forms. Even Molded parts made of plastic can be produced in this way if the individual parts glued together. But now there are various plastics gluing is not so easily feasible. So z. B. prepares the @ flawless Always stick the Kuans @ tsitoffe made of polyacrylic or polym @ ethacrylic derivatives ; Great skiing, if you use the adhesive previously intended for this purpose Läsumgsmttel used: These solvents used up to now have known to have the Disadvantage that they are between the glue joints, especially if they are a bit wider fail, do not evaporate completely. Adhesive joints made in this way boiled so not equally good over their entire surface and on the one hand mechanically satisfactory eight and on the other hand, especially in electrical terms, not because of them insufficient dielectric strength.

Ein Klebverfahren für die vorgenanrnten Kunststoffe, dem :die ,aufgezeigten Nachteile nicht anhaften, bürgt die Erfindung.A bonding process for the aforementioned plastics, the: the, indicated Disadvantages do not adhere to the invention.

Erfindungsgemäß werden. zurr Verklebten von Kunststoffteilen aus Polyacryl- bzw. Polymethacrylderivaten mit Äthylenimidharz moidifizier-te unges:ät@-te Polyesterharze verwendet, denen eine geringe Menge eines H,ärters zugesetzt ist. Als Härter kam z. B. Schwefelsäuneester beigemengt werden.Be according to the invention. for gluing plastic parts made of polyacrylic or polymethacrylic derivatives with ethylene imide resin moidified uns: ät @ -te polyester resins used to which a small amount of a hardener is added. When hardener came z. B. sulfuric acid esters are added.

Das erfindungsgemäße Klebverfahren bringt bisher weder in mechanischer noch in elektrischer Hinsicht erreichte ;gute Verklebungen. Da der verwendete Klebstoff unter der Einwirkung des Här temi:ttels sich verfestigt, ohne dabei irgendwelche Gäste -oder Dämpfe abzuspalten, spult es bei dem erfimidungsgemäßen Klebverfahren keine Rolle, wie breit diie Klebefugen gemacht werden. Es können somit auch großflächige Fugen ohne weiteres her- gestellt werden.. Das .erfiindun;gägemiäße Verfahren,eignet sich vor allem zum Verklebiem vorn glasklaren Teileng aus Pgolyacryls;aureies.term, z. B. Polyxnethacrylsäur--- mIethyliester, die nicht nur mechaunisch feist, sondern vor gallem ,auch gelektrisch fest miteinander zu ver- binden sind, z. B. bei Spulenkästen für gelehtro- techmische Zweckte, Kapseln für .elektrische Spulen, Isollzrungien vorn - Meßwandlern, Schalem für Kathodenfallableiter usw. The adhesive bonding process according to the invention has hitherto not produced good bonds, either mechanically or electrically. Since the adhesive used solidifies under the action of the hardening temi: ttels, without any Splitting off guests or vapors, it winds up with that adhesive method according to the invention does not matter how wide the glue joints are made. It can thus also large-area joints easily be asked .. The invented procedure is suitable especially to the gluing in front of crystal clear parts Pgolyacryls; aureies.term, e.g. B. Polyxnethacrylic acid --- methyl esters who are not only mechanically fat, but also before gallem, also electrically firmly to bind, z. B. for bobbins for gel-thro- technical purposes, capsules for electrical coils, Isollzrungien in front - transducers, shells for Cathode drop arrester, etc.
