Abstract
The invention discloses a ceramic bond and a preparation method thereof. The ceramic bond is prepared from the following substances in parts by weight: 20-30 parts of Na2O, 30-40 parts of B2O3, 45-50 parts of Al2O3, 15-30 parts of SiO2, 8-10 parts of Li2CO3, 1-5 parts of KNO3 and 5-10 parts of TiO2. 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 3-5 hours; pouring the water out, and baking at 90-110 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 ceramic bonding agents, and specifically relates to a ceramic bonding agent and a preparation method thereof. Background technique [0002] Because the ceramic bond has the advantages of good thermal stability, high rigidity, and controllable porosity, the ceramic bond cubic boronnitrideabrasive tool has the advantages of high strength, good self-sharpening, and easy dressing. Structural elements such as abrasive particles, bonding agent and pores together determine the performance of the abrasive tool. The mildness of the vitrified bond grinding wheel mainly depends on the strength of the vitrified bond itself and the bonding strength between the bond and abrasive particles. The composition of the bond is an important factor that affects the strength of the ceramic bond and the bond strength between the bond and the abrasive particles. With the advancement of science and technology, the ceramic bond i...
