Description
Die Erfindung betrifft einen Bindemittelversntz, der bei der Herstellung von keramisch gebundenen Korundschleifkörpern für Umfangsgeschwindigkeiten bis 35m/s Anwendung findet.The invention relates to a binding agent used in the production of ceramic bonded corundum abrasive bodies for peripheral speeds up to 35m / s application.
Die Herstellung und Anwendung keramisch gebundener Schleifkörper wird in hohem Maße von der Beschaffenheit und dem thermischen Verhalten des keramischen Bindemittels bestimmt. Zur Gewährleistung einer konstanten Schleifkörperqualität müssen enge Toleranzwerte in der Zusammensetzung des Bindemittels eingehalten werden.The manufacture and use of ceramic bonded abrasive articles is largely determined by the nature and thermal behavior of the ceramic binder. To ensure a constant abrasive quality, close tolerances must be maintained in the composition of the binder.
Neben den üblichen Bindemittelzusammensetzungen auf der Basis von Kaolin und Feldspat (z. B. SU 808 259) sind auch Bindemittel auf der Grundlage glimmerreicher Sande, die 0,4-0,7 Masseanteile Glimmer der Mischkristallreihe Zinnwaldit-Protolithionit enthalten (DD 222240), bekannt. Nach DD 227638 ist es möglich, Spiegelglaspulver oder Gemische aus Spiegelglaspulver und unbelegtem Glaspulver mit einer Teilchengröße von <63μηη als Bindemittel zur Herstellung keramisch gebundener Schleifkörper einzusetzen. Nachteilig bei den aufgeführten Bindemitteln sind die erforderlichen hohen Brenntemperaturen bei der Schleifkörperherstellung, die z.B. beim Bindemittel gemäß DD 227638 bei über 1250°C liegen. Der Nachteil der hohen Brenntemperaturen kann durch den Einsatz von borhaltigen Bindemitteln (SU 1247 253, DE 2211442, DE 2345759, DE 3616257, GB 1194110) oder Bindemitteln auf der Basis eines Bleiglases (SU 573336) beseitigt werden. Nachteilig beim Einsatz borhaltiger Bindemittel bzw. der Bindemittel auf Bleiglasbasis sind jedoch die bedeutend höheren Rohstoffkosten. Deshalb wurde in der DD 255640 vorgeschlagen, bis zu 50 Masseanteile in % des borhaltigen Bindemittels durch aufgemahlenes Flachglas zu ersetzen.In addition to the usual binder compositions based on kaolin and feldspar (eg SU 808 259), there are also binders based on mica-rich sands which contain 0.4-0.7% by weight of mica of the mixed-crystal series tin-forestite protolithionite (DD 222240), known. According to DD 227638 it is possible to use mirror glass powder or mixtures of mirror glass powder and uncoated glass powder with a particle size of <63μηη as a binder for the production of ceramic-bonded abrasive articles. A disadvantage of the binders listed are the required high firing temperatures in the abrasive article production, e.g. when binder according to DD 227638 at over 1250 ° C. The disadvantage of the high firing temperatures can be eliminated by the use of boron-containing binders (SU 1247 253, DE 2211442, DE 2345759, DE 3616257, GB 1194110) or binders based on a lead glass (SU 573336). However, the disadvantage of using boron-containing binders or binders based on lead glass is the significantly higher raw material costs. For this reason DD 255640 proposed replacing up to 50% by weight of the boron-containing binder by means of ground flat glass.

Der Erfindung liegt die technische Aufgabe zugrunde, eine bor- und bleifreie Bindemittelzusammensetzung für die Schleifkörperherstellung zu entwickeln, die die Sinterung der Schleifkörper bei Temperaturen £ 1250°C gestattet.

According to the invention, the technical object is achieved in that the binder offset a mixture of
