Abstract
The invention relates to a ceramic bonding agent, in particular to a ceramic bonding agent containing rare-earth metal. A preparation method of the ceramic bonding agent containing rare-earth metal comprises the following steps that firstly, according to weight percentages, 55%-60% SiO2, 11%-15% Al2O3, 8.5%-10% B2O3, 12-15% K2O, 1-5% BaO and 0.5%-2% rare-earth metal are taken, raw materials are put into a ball mill to be ground uniformly to be prepared for use; secondly, the uniformly ground raw materials are put into a high-temperature furnace to be calcined, the calcination temperature is 1100-1400 DEG C, and time is 1-2h; thirdly, products obtained in the second step are dried, put into the ball mill to be ground and screened for 250 meshes, and the ceramic bonding agent containing rare-earth metal is obtained. After the rare-earth metal is led into the ceramic bonding agent, dispersity of the bonding agent is improved, and the service life of a manufacturing tool is greatly prolonged and is 1.5-2 times that of an original tool.
Description
Technical field
The present invention relates to a kind of vitrified bond, especially a kind of vitrified bond that contains rare earth metal.
Background technology
Emery wheel is comprised of abrasive particle, bonding agent and three Fundamentals of pore, and abrasive particle mainly plays shear action, and pore mainly plays chip removal and cooling effect, and the Main Function of bonding agent has: (one) is bonded together abrasive particle, makes the emery wheel of various shapes; (2) after making emery wheel fixed, can bear certain grinding force and revolution tangential stress, there is enough revolving strengths; (3) make after Abrasive Grain blunt, be subject to External Force Acting can produce different Automatic-falling abilities, make various hardness, during work, produce sharping by oneself affect.Therefore, on emery wheel product quality, particularly intensity, hardness have vital impact in the selection of bonding agent.For vitrified abrasive, the properties of product of its high-quality depend mainly on well behaved vitrified bond.General vitrified bond be take sial glass as basis, introduces some alkali metal oxides and alkaline earth oxide to regulate the performances such as the charge balance of bonding agent and the fusing point of bonding agent, intensity.But the wheel life of utilizing such vitrified bond to prepare is generally shorter, and the dispersiveness of vitrified bond is general.
Summary of the invention
The invention provides a kind of vitrified bond that contains rare earth metal, solved the bad dispersibility of existing vitrified bond, the problem that the life-span is short.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A vitrified bond that contains rare earth metal, according to weight percent meter, comprises rare earth metal and the oxide thereof of 0.5%-2%.
