The manufacturing method comprises the steps of mixing the rare earth oxide material with the siliceous material and the aluminum-containing material, then performing smelting, performing cooling, ball milling and screening, then mixing with a grinding material, performing sintering and then performing trimming by turning. Through the method, the invention can enable the grinding wheel to have the characteristics of high strength, high self-sharpening performance and long service life.
Description
Technical field
The present invention relates to a kind of rare-earth ceramic bonding agent, belong to field of new; Also relate to the manufacture method of the emery wheel using this bonding agent simultaneously.
Background technology
Emery wheel is a topmost class grinding tool in grinding.Emery wheel adds bonding agent in abrasive material, the porous body made through pressed compact, drying and roasting.Because abrasive material, bonding agent and manufacturing process are different, the characteristic difference of emery wheel is very large, therefore to the crudy of grinding, productivity ratio and economy important.
At present, roller abrasive wheel conventional on market generally adopts resinoid bond, and its intensity is not high, the life-span is low, sharpness is general, and duration of work can produce ammonia serious environment pollution, infringement workman is healthy; And a small amount of vitrified bonded grinding wheel exists that intensity is not high, the life-span general and the more high unfavorable factor of cost, thus have impact on its application commercially.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide a kind of rare-earth ceramic bonding agent and uses the manufacture method of emery wheel of this bonding agent.The emery wheel produced effectively can improve the shortcomings such as the intensity of existing emery wheel is low, the life-span is low, sharpness is low, self-sharpening is poor, cost performance is low, environmental pollution.
The solution of the present invention is as follows: a kind of rare-earth ceramic bonding agent, it is characterized in that comprising following heavy part raw material: the rare earth oxide material of 5-15%, 50-60% siliceous material, 15-20% alumina-bearing material and 15-20% boric acid.
Further, described rare earth oxide material is one, two or three in neodymia, yittrium oxide and lanthana.
Further, described siliceous material is the one, two or three in quartz sand, albite, pyrophillite, prodan.
Further, described alumina-bearing material is the one, two or three in aluminium powder, aluminium oxide, aluminium hydroxide, sodium metaaluminate four kinds of materials.
A kind of manufacture method of the emery wheel of rare-earth ceramic bonding agent that uses is as follows:
(1) rare earth oxide material is mixed with siliceous, alumina-bearing material and boric acid;
(2) mixed rare earth and siliceous raw material are put into high temperature melting furnace melting 1-3 hour, form liquid rare earth vitrified bond;
(3) poured into by liquid rare earth vitrified bond in the container of inert gas and carry out cooling crystallization, after control flow rate of gas makes bonding agent crystallization, granularity is 300-500 order;
(4) bonding agent is mixed with two or three abrasive material in CBN, SiC, Al2O3;
(5) poured in roller abrasive wheel hot pressing die by the raw material after mixed and sinter, Stress control is at 5-10MPa, and sintering time is 20-40 minute, and sintering temperature controls at 600-800 DEG C;
(6) the burned rear turning of emery wheel is trimmed to qualified size, encapsulation warehouse-in;
Further, described inert gas is the one in nitrogen, argon gas or helium.
Further, hot pressing die material is the one in graphite, heat resisting steel or boron nitride material.
Present invention achieves three high characteristics of the high strength of roller abrasive wheel, high life, high sharpness, and there is environmental friendliness, outstanding advantage that cost performance is excellent.Rare earth bonding agent is smelted into liquid phase by the present invention, and realizes cooling and crystallization by inert gas, and make each species distribution of emery wheel after producing even, stability, intensity are better.
