Abstract

The invention discloses a high-strength ceramic bond and a preparation method thereof. The ceramic bond is composed of the following substances of, by weight, 1-3 parts of sodium pyrophosphate, 5-8 parts of borax, 2-3 parts of sodium silicate, 0.02-0.05 part of magnesium oxide, 1-2 parts of modified phenolic resin, 0.5-0.8 part of calcite, 0.2-0.4 part of barium sulfate and 0.1-0.5 part of calciumcarbonate. All raw materials are sufficiently mixed in a ball mill, then water is added, ball milling is conducted for 6-8 h, and then still standing is conducted for 3-4 h; and the water is poured out, drying is conducted under the condition of 95-105 DEG C, and then ball milling and sieving are conducted to prepared and obtain the ceramic bond. The prepared ceramic bond has the characteristicsof being low in fire resisting degree and high in strength.

Description

technical field [0001] The invention belongs to the technical field of vitrified bonding agent, and in particular relates to a high-strength vitrified 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 and te...
