Description
Man hat schon vielfach versucht, das zum Löten erforderliche Lot mit den gleichzeitig zu benutzenden Lötmitteln (Harz, Chlorzink o. dgl·.) ziu einem handlichen Körper ziu vereinigen, wodurch die bekannten Lötstäbe und Lötpasten entstanden sind. Die bekannten Lötstäbe, bei denen die als Lot dienende Legierung zerkleinert und dann mit den Lötmitteln durch Pressen, gegebenenfalls unter Erwärmung, zu einem stabförmigen Körper vereinigt Ist, haben den Nachfeil, daß die erhaltenen Stäbe nicht die genügende mechanische Festigkeit besitzen.Many attempts have already been made to achieve this Solder the required solder with the soldering agents to be used at the same time (resin, zinc chloride o. the like.) to unite a manageable body ziu, whereby the well-known soldering rods and soldering pastes were created. The known Soldering bars in which the alloy serving as solder is crushed and then with the solder combined by pressing, possibly with heating, to form a rod-shaped body Is, have the disadvantage that the rods obtained do not have sufficient mechanical Possess strength.
Gemäß der Erfindung wird diesem Übelstände dadurch abgeholfen, daß man nicht die fertige Legierung in gekörnter Form benutzt, sondern die einzelnen Metalle in Körnerform mit den Lötmitteln vereinigt.According to the invention, this becomes a problem helped by not using the finished alloy in granular form, but the individual metals in grain form combined with the solder.
Die Metalle, vorzugsweise Blei und Zinn,The metals, preferably lead and tin,
so werden in bekannter Wieise gekörnt, so daß das Metall etwa die Form eines groben Sandes erhält. Die einzelnen Metalle werden in dem gewünschten Mengenverhältnis gemischt, wobei erforderlichenfalls noch weitere Metalle, wie Antimon, Wismut, Kadmium o. 'dgl., ebenfalls in Körnerform zugesetzt werden können. Das erhaltene Metallgemisch wird mit dem Lötmittel vermischt, das als Pttlver ! (Kolophonium, andere Harze o. dgl.) oder als , steifer Brei (Chlorzink, Glyzerin, Natrium-I phosphat usw.) benutzt wird. Nachdem die ; Masse gut durchgemischt, ist, wird sie in einer : Presse, gegebenenfalls unter schwacher Eri wärmiung, jedoch nicht bis zum Schmelzpunkt t der Bestandteile, in Stangen gepreßt.so are grained in the known way, so that the metal is roughly in the form of coarse sand. The individual metals are mixed in the desired proportions, further metals such as antimony, bismuth, cadmium or the like, likewise being able to be added in granular form, if necessary. The resulting metal mixture is mixed with the solder, which is available as a Pttlver! (Rosin, other resins or the like) or as a stiff paste (chlorzinc, glycerine, sodium phosphate, etc.) is used. After the ; By mass mixed well, it will in a: wärmiung press, optionally with the weak Eri, but not up to the melting point of t of the components pressed into bars.
} Bei diesem Preßvorgang fließt das Blei ! unter der Einwirkung des Druckes sehr leicht, während' die 'Zinnkörner ihre Form nicht wesentlich ändern. Das Blei umfaßt dabei die Zinnkörner, und da ein Bleikörnchen stets mehrere benachbarte Zinnkörnchen umklammert, tritt eine vollkommene Verfilzung der verschiedenen Metalle und des Lötmittels ein. Man' erhält auf diese Weise einen Lötstab, der eine sehr viel größere Festigkeit besitzt als' die bisher bekannten, so daß er besser als diese benutzt werden kann.} The lead flows during this pressing process! very easily under the action of pressure, while 'the' tin grains do not change their shape significantly. The lead includes the Grains of tin, and since a grain of lead always clasps several neighboring grains of tin, a perfect matting of the various metals and solder occurs. In this way, a soldering rod is obtained which has a much greater strength than the ones previously known, so that it can be used better than these.
