Description

Auf Silikonkautschuk haftende Überzüge bildende Silikonharzlacke Es ist bereits bekannt, zur Verbesserung der Haftfähigkeit von Silikonharzen auf Silikongummi den Silikongummi mit bestimmten Grundierungen zu versehen, wobei Kieselsäureester, Titanate, Silane gegebenenfalls in Kombination mit hochvernetzten, reinen Methylsilikonharzen verwendet werden (deutsche Auslegeschrift 1071790). Diese Grundierungen haben den Nachteil, daß sie den Silikongummi nicht genügend benetzen. Um eine ausreichende Haftung des Silikonharzes auf dem Silikongummi zu erreichen, muß es zur Erzielung eines gleichmäßigen Silikonharzfilmes mechanisch eingerieben werden, wobei mit Fehlstellen gerechnet werden muß. Silicone resin lacquers that form coatings that adhere to silicone rubber It is already known to provide the silicone rubber with certain primers to improve the adhesion of silicone resins to silicone rubber, silicic acid esters, titanates, and silanes optionally being used in combination with highly crosslinked, pure methyl silicone resins (German Auslegeschrift 1071790). These primers have the disadvantage that they do not sufficiently wet the silicone rubber. In order to achieve adequate adhesion of the silicone resin to the silicone rubber, it must be mechanically rubbed in to achieve a uniform silicone resin film, and defects must be expected.

Erfindungsgemäß gelingt es, einen gleichmäßigen, festhaftenden Überzug eines Silikonharzes auf einer Silikongummioberfläche zu erzeugen, ohne daß eine besondere Vorbehandlung des Silikongummis erforderlich wird (Fortfall einer besonderen Grundierung).According to the invention it is possible to obtain a uniform, firmly adhering coating of a silicone resin on a silicone rubber surface without a special pretreatment of the silicone rubber is required (omission of a special Primer).

Erfindungsgemäß werden Silikonharze, wie Methyl-, Methylphenyl- bzw. polyestermodifizierte Silikonharze, in Kombination folgender Zusätze verwendet: 1. In organischen Lösungsmitteln lösliche, als- Härter für Silikonharze an sich bekannte Metallsalze, vorzugsweise Metallsalze organischer Säuren, wie Kobalt-, Blei-, Mangannaphthenat oder -octoat, 2. Titansäureester und bzw. oder Ester des Aluminiums sowie deren Chelate mit a,p-Diketonen oder Aminen, 3. Kieselsäureester und bzw. oder Alkoxysilane und bzw. oder Polykieselsäureester, 4. Fettsäureverbindungen von Organozinn- oder Organogermaniumderivaten, insbesondere Dibutylzinndilaurat.According to the invention, silicone resins such as methyl, methylphenyl or polyester-modified silicone resins, used in combination of the following additives: 1. Soluble in organic solvents, as a hardener for silicone resins per se known metal salts, preferably metal salts of organic acids, such as cobalt, Lead, manganese naphthenate or octoate, 2nd titanic acid ester and / or ester of Aluminum and their chelates with a, p-diketones or amines, 3. Silicic acid esters and / or alkoxysilanes and / or polysilicic acid esters, 4. fatty acid compounds of organotin or organogermanium derivatives, especially dibutyltin dilaurate.

Zweckmäßig werden die Silikonharze mit den Zusätzen nach der Erfindung in Form von Lösungen auf die Silikongummioberfläche aufgebracht.The silicone resins with the additives according to the invention are expedient applied in the form of solutions to the silicone rubber surface.

Als Beispiel für die Kombination nach der Erfindung können reine oder modifizierte Silikonharze in folgendem Verhältnis der Zusätze Verwendung finden: 79,20/, Silikonharz, 750/aig in Toluol, 1,50/a Bleinaphthenat, 200/aig in Toluol, 4,80/a einer 43%igen Lösung von Tetrabutyltitanat in Acetessigester, 3,30/, Orthoäthylsilikat, 0,40/a Dibutylzinndilaurat, 6,30/, Xylol, 4,50/a Butanol.As an example of the combination according to the invention, pure or modified silicone resins are used in the following ratio of additives: 79.20 /, silicone resin, 750 / aig in toluene, 1.50 / a lead naphthenate, 200 / aig in toluene, 4.80 / a of a 43% solution of tetrabutyl titanate in acetoacetic ester, 3.30 /, orthoethylsilicate, 0.40 / a dibutyltin dilaurate, 6.30 / a, xylene, 4.50 / a butanol.

An Stelle der Komponenten nach 3. können gegebenenfalls auch Borsäureester verwendet werden. Trägt man derartige Lacke auf vulkanisierte oder nicht bzw. nur halbvulkanisierte Gummischichten auf und härtet sie bei 180°C aus, so werden Überzüge erreicht, die so innig mit dem Silikongummi sich vereinigen, daß sie sich nicht mehr abziehen lassen. Dies ist wichtig bei der Herstellung von Isolierwicklungen, welche eine besondere mechanische Festigkeit und Feuchtigkeitsschutz erhalten sollen.Instead of the components according to 3, boric acid esters can optionally also be used be used. If you wear such varnishes on vulcanized or not or only semi-vulcanized rubber layers and harden them at 180 ° C, so are coatings achieved that unite so intimately with the silicone rubber that they do not let more peel off. This is important in the manufacture of insulating windings, which should receive a special mechanical strength and moisture protection.
