Abstract
The invention discloses a low-temperature ceramic bond and a preparation method thereof. The ceramic bond is prepared from the following substances in parts by weight: 36-45 parts of SiO2, 23-33 parts of B2O3, 30-40 parts of Fe2O3, 2-8 parts of CaO, 7-10 parts of Li2CO3, 3-5 parts of KNO3 and 6-9 parts of Na2O. The preparation method comprises the following steps: sufficiently mixing all raw materials in a ball mill; adding water, carrying out ball milling for 10-15 hours, and standing for 3-4 hours; pouring the water out, and baking at 90-105 DEG C; and carrying out ball milling, and screening to prepare the ceramic bond. The prepared ceramic bond has the characteristics of low refractoriness and high strength.
Description
technical field [0001] The invention belongs to the technical field of vitrified bonding agent, and in particular relates to a low-temperature ceramic bonding agent and a preparation method thereof. Background technique [0002] Because the vitrified bond has the advantages of good thermal stability, high rigidity, and controllable porosity, the vitrified cubic boron nitride abrasive tool has the advantages of high strength, good self-sharpening, and easy dressing. Structural elements such as abrasive grains, bonds and pores jointly determine the performance of abradable tools. The lightness of the vitrified bond grinding wheel mainly depends on the strength of the vitrified bond itself and the bonding strength between the bond and the abrasive particles. The composition of the bond is an important factor affecting the strength of the vitrified bond and the bonding strength of the interface between the bond and the abrasive particles. With the advancement of science an...
