Problems solved by technology

Considering the needs of energy saving at low temperature, boron glass and other fusible substances are generally added to reduce the refractoriness of the binder without reducing the bonding strength of the binder, but this often increases the production cost of the vitrified binder

Abstract

The invention discloses a white corundum ceramic grinding wheel binder added with architectural glass wastes, and belongs to the technical field of bonded abrasive tool manufacturing. The white corundum ceramic grinding wheel binder is obtained through milling and mixing potassium feldspar, clay, talc and recycled architectural glass wastes according to a certain proportion, wherein all components are subjected to synergistic effect within a limited dosage range, so that the sintering temperature and use performance of the ceramic binder are ensured, the maximum sintering temperature does not exceed 1260 DEG C, and the white corundum ceramic grinding wheel binder is suitable for manufacturing ceramic grinding wheels by using milled white corundum. The white corundum ceramic grinding wheel binder is good in wettability to milled white corundum, strong in holding force, and good in abrasive tool self-sharpening property. The grinding wheel prepared by using the binder is high in rotating strength, has a use line viscosity of 63 m / s or more, and high in durability; a workpiece has no burn cracks; the recycled architectural glass wastes are milled and used for preparing the white corundum ceramic grinding wheel binder, so as to reduce the cost of raw materials of the binder and reduce non-renewable mineral resources.

Description

technical field [0001] The invention belongs to the technical field of bonded abrasive tool manufacturing, and in particular relates to a white corundum ceramic grinding wheel bond added with construction glass waste and a preparation method thereof. Background technique [0002] Grinding wheel is an important tool for mechanical processing. Vitrified grinding wheel is an abrasive tool made by combining loose and barren granular abrasives at high temperature with a vitrified bond. Vitrified grinding wheels have the advantages of high grinding efficiency, high processing precision, and low cost. Vitrified bond is the key raw material for preparing vitrified grinding wheels. Under the premise that the abrasive has been determined, the performance of the bond such as temperature and bonding strength determines the grinding wheel. The safe use performance and firing temperature. The safe use requirements of grinding wheel products in use stipulate that the insurance factor is a...
