Abstract
Description
Spachtelmasse Die Erfindung betrifft eine Spachtelmasse zum Schutt metallischer Geräte- oder Maschinenteile der keramischen Industrie oder der Bautechnik vor vorzeitigen VerschlaiB, die neben Elektrokorund, Silioiuncarbid und Glasquarz ein Bindemittel enthält, nach Patent . . . . . (Patentanmeldung P 21 49 529.4). Filler The invention relates to a filler for rubble metallic device or machine parts of the ceramic industry or construction technology against premature wear, in addition to electrical corundum, silicon carbide and glass quartz contains a binder, according to patent. . . . . (Patent application P 21 49 529.4).
Dieae Spachtelmasse wird an dem Ort ihrer Verwendung z.. auf der Baustelle mit einem Härter angerührt und auf die vor Verschleiß zu schützenden Flächen mit einer Spachtel je nach Bedarf zwischen 2 und 10 mm aufgetragen. Nach einer Aushärtungszeit von ca.- 6 Stunden ist die Spachtelmasse derartig hart und verschleißfest, daß die zu schützenden Teile eine vier- bis fünffache Standzeit erreichen. Diese Werte wurden durch praktische Versuche an Mischflügeln von Betonmaschinen und glatten Rutschen bei Kieswerken ermittelt.The leveling compound is applied at the place where it is used, e.g. on the construction site mixed with a hardener and applied to the surfaces to be protected from wear a spatula applied between 2 and 10 mm as required. After a curing time from about 6 hours the filler is so hard and wear-resistant that the parts to be protected achieve four to five times the service life. These values were through practical experiments on mixing blades of concrete machines and smooth slides determined at gravel works.
Einen besonders guten Spachtel erhält man, wenn man einen Kunststoff auf Polyurathaßsbasix, z.B. Polyglykolätherisocyanat verwendet, da dieser sehr widerstandsfähig und säurefest, z.B. gegenüber Moorsäure, ist.You get a particularly good spatula if you use a plastic based on polyurate, e.g. polyglycol ether isocyanate, because it is very resistant and is acid-resistant, e.g. to moor acid.
Ebenso ist es zweckmäßig der Spachtelmasse zur Verdikkung und Thixotropierung pyrogene Kieselsäure zuzusetzenit Beispiel für die Zusammensetzang der Spachtelmaßse 20 % Elektrokorund mit einer Siebung nach Fepa 70, 24 % Elektrokorund mit einer Siebung nach Fepa 24, 28 % Siliciumcarbid mit einer Siebung nach Fepa 24, 20 0 Siliciumcarbid mit einer Siebung nach Fepa 70, 7 % Kunststoff auf Polyätherisocyanat-Basis, 1 % pyrogene Kieselsäure.It is also useful to thicken and thixotrope the filler Add fumed silica as an example of the composition of the spatula 20% electro corundum with a sieving according to Fepa 70, 24% electro corundum with a Sieving according to Fepa 24, 28% silicon carbide with a sieving according to Fepa 24, 20th 0 silicon carbide with sieving according to Fepa 70, 7% plastic based on polyether isocyanate, 1% fumed silica.
Zur Herstellung dieses Spachtels werden Elektrokorund und Siliciumcarbid mittels eines Kneters,Sandmühle, Ein- oder Dreibarrenwalze innig vermischt. Dieser Vorgang dauert ca. 5 bis 7 Minuten. Nach dieser Zeit wird der Kunststoff beigegeben und abermals ca. 2 bis 3 Mi nuten gemischt. Anschließend wird die pyrogene Kieselsäure in die Mischung eingearbeitet. Die hierdurch eintretende Thixotropierung bewirkt, daß der Spachtel auch auf Flächen von 50 - 750 aufgetragen werden kann, ohne daß er durch sein Eigengewicht absackt. Die Aushärtungszeit des Spachtels beträgt bei 100 C 20 Stunden und bei 230 C 5 Stunden. Die mit dem Spachtel überzogenen Plächen sind äußerst verschleißfest.Electro-corundum and silicon carbide are used to manufacture this filler intimately mixed by means of a kneader, sand mill, single or three-bar roller. This The process takes about 5 to 7 minutes. After this time, the plastic is added and mixed again for about 2 to 3 minutes. Then the fumed silica incorporated into the mixture. The resulting thixotropy causes that the putty can also be applied to areas of 50 - 750 without it sags under its own weight. The hardening time of the filler is 100 C for 20 hours and at 230 C for 5 hours. The surfaces covered with the spatula are extremely wear-resistant.
Da es sich bei dem verwendeten Kunststoff um feuchtigkeitstrocknende Polyurethane handelt, kann die Aushärtungszeit durch Besprühen mit Heißdampf (nicht über 1500) auf 20 bis 30 Minuten herabgesetzt werden.Since the plastic used is moisture-drying Polyurethane, the curing time can be reduced by spraying with hot steam (not over 1500) can be reduced to 20 to 30 minutes.
Durch die Verbindung von erhöhten N-C-O-Gruppen als auch OH-Gruppen wird es ermöglicht den Härter der Spachtelmasse bereits vor Auslieferung beizumischen, denn die überschüssigen N-C-O-Gruppen finden keinen Reaktionspartner in der Spachtelmasse und suchen sich ihre OH-Partner in der Buftfeuchtigkeit oder auch im luftfeuchten Untergrund. Selbstverständlich kann nicht auf sichtbare Nässe gearbeitet werden, weil sonst der Spachtel schlagartig reagiert, ohne eine befriedigende Verbindung mit dem Untergrund herzustellen.By connecting elevated N-C-O groups as well as OH groups it is possible to mix the hardener with the filler before delivery, because the excess N-C-O groups find no reaction partner in the filler and look for their OH partner in the humidity or also in humid underground. Of course, it cannot be visibly wet because otherwise the spatula reacts suddenly without a satisfactory one Establish a connection with the subsurface.
Der vorgeschlagene Spachtel ergibt keine hart-spröden, sondern zäh-harte, elastische Schichten.The proposed spatula does not produce hard-brittle, but tough-hard, elastic layers.
