Abstract
The invention discloses a kind of rare-earth ceramic bonding agent, including rare earth oxide material, siliceous material, alumina-bearing material and boric acid.The invention also discloses the manufacture method of the emery wheel using the bonding agent, it carries out melting after rare earth oxide is mixed with siliceous and alumina-bearing material, merges after supercooling, ball milling, sieving with abrasive mixed and be sintered, and sinters laggard driving and cuts finishing.By the above-mentioned means, the present invention can make emery wheel have high intensity, high self-sharpening, the three of the high life high features.
Description
Technical field
The present invention relates to a kind of rare-earth ceramic bonding agent, belong to field of new materials；Also relate to using the bonding agent
The manufacture method of emery wheel.
Background technology
Emery wheel is most important a kind of grinding tool in grinding.Emery wheel is that bonding agent is added in abrasive material, through pressed compact, drying
With roasting and manufactured porous body.Because abrasive material, bonding agent and manufacturing process are different, the characteristic difference of emery wheel is very big, therefore right
Crudy, productivity ratio and the economy important of grinding.
At present, the conventional roller abrasive wheel of in the market generally uses resinoid bond, and its intensity is not high, the life-span is low, sharpness
Typically, and during working it can produce ammonia and seriously pollute environment, infringement worker's health；And a small amount of vitrified bonded grinding wheel
The unfavorable factors such as intensity is not high, the life-span is general and cost is higher again be present, so as to have impact on its application commercially.
The content of the invention
To overcome above-mentioned deficiency, the emery wheel it is an object of the present invention to provide a kind of rare-earth ceramic bonding agent and using the bonding agent
Manufacture method.The emery wheel of production can be effectively improved the low intensity of existing emery wheel, the life-span is low, sharpness is low, self-sharpening is poor, property
The shortcomings of valency is than low, environmental pollution.
The solution of the present invention is as follows：A kind of rare-earth ceramic bonding agent, it is characterised in that including following heavy part raw material： 5-15%
Rare earth oxide material, 50-60% siliceous materials, 15-20% alumina-bearing materials and 15-20% boric acid.
Further, described rare earth oxide material be in neodymia, yittrium oxide and lanthana it is a kind of, two or three.
Further, described siliceous material be quartz sand, albite, pyrophillite, one kind in prodan, two kinds or three
Kind.
Further, described alumina-bearing material be aluminium powder, aluminum oxide, aluminium hydroxide, one kind in four kinds of materials of sodium metaaluminate,
Two or three.
A kind of manufacture method of emery wheel using rare-earth ceramic bonding agent 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 melting 1-3 hours in high temperature melting furnace, form liquid rare earth pottery
Porcelain bonding agent；
（3）Liquid rare earth vitrified bond is poured into the container of inert gas and carry out cooling crystallization, control gas stream
Granularity is 300-500 mesh after dynamic speed makes bonding agent crystallization；
（4）Bonding agent is mixed with two or three of abrasive material in CBN, SiC, Al2O3；
（5）Raw material after will be mixed is poured into roller abrasive wheel hot pressing die and sintered, and Stress control is in 5-10MPa, sintering
Between be 20-40 minutes, sintering temperature is controlled at 600-800 DEG C；
（6）Turning is trimmed to qualified size, encapsulation storage after emery wheel is burned；
Further, described inert gas is one kind in nitrogen, argon gas or helium.
Further, hot pressing die material is one kind in graphite, heat resisting steel or boron nitride material.
The present invention realizes high intensity, high life, the three of the high sharpness high characteristics of roller abrasive wheel, and with environment friend
Outstanding advantage good, cost performance is excellent.Rare earth bonding agent is smelted into liquid phase by the present invention, and is realized and cooled down by inert gas
And crystallization so that each material of emery wheel after production is evenly distributed, and stability, intensity are more preferable.
