Abstract
The invention discloses a high-strength ceramic bond. The ceramic bond comprises the following ingredients in parts by weight: 35-45 parts of feldspar, 15-25 parts of clay, 5-15 parts of borosilicate glass, 5-15 parts of bentonite, 10-20 parts of spodumene and 4-6 parts of quartz. The ceramic bond is prepared from the following steps: mixing the ingredients for ball milling for 30 minutes with the weight ratio of raw meal pellets of 3:1, and carrying out calcining after passing through an 80-mesh screen with the highest firing temperature of 1200 DEG C; carrying out ball milling once again after calcining for 120 minutes with the weight ratio of raw meal pellets of 1:3, and passing through a 320-mesh screen. According to the ceramic bond, bentonite, spodumene, quartz and other ingredients are introduced into the ceramic bond, so that refractoriness of the ceramic bond is reduced, the formation of the glass phrase is promoted, strength of the ceramic bond is improved, and the strength, the safety performance, the qualification rate and the like of a high-speed ceramic grinding wheel can be effectively improved; when the ceramic bond is used for a regular ceramic grinding wheel, the dosage of the ceramic bond can be reduced, the grinding efficiency and effects of a grinding wheel are improved, and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to a kind of bonding agent manufacturing emery wheel, especially for the high-strength ceramic bonding agent manufacturing ceramic concretion abrasive wheel.
Background technology
Emery wheel is made up of abrasive particle, bonding agent and pore three fundamental factor, 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 different shape; (2), after making emery wheel consolidation, certain grinding force and revolution tangential stress can be born, there is enough revolving strengths; (3) after making Abrasive Grain blunt, different Automatic-falling abilities can be produced by External Force Acting, namely make various hardness, during work, produce sharping by oneself affect.Therefore, on emery wheel quality product, particularly intensity, hardness have vital impact in the selection of bonding agent.For vitrified grinding wheel, the product performance of its high-quality depend mainly on ceramic bond of good performance.Current domestic and international existing ceramic bond is of a great variety, along with the progress of science and technology and the development of scientific research, difficult-to-grind material kind increases, grinding process is updated, new junction agent also gets more and more, and has clay-feldspar, clay-feldspar-boron glass class, clay-feldspar-talcs, boron glass-quartz-soda ash class etc.But to manufacture high speed ceramic emery wheel (using linear velocity V >=60m/s), the problems such as ubiquity intensity does not pass a test, quality unstable, scrap rate is high, security is low, its major cause is that the liquid phase that bonding agent is formed when high temperature burns till is inadequate, refractoriness is higher.There are some producers, adopt the method increasing boron glass content, but the fragility of emery wheel can be caused to increase, affect safety performance.Ling You producer, employing strengthens the ratio of bonding agent and abrasive material, though this method can solve the strength problem of emery wheel, due to the increase in conjunction with dosage, the void content of emery wheel diminishes, hardness increases, and affects ground effect.
Summary of the invention
The object of the invention is to solve the strength problem manufacturing vitrified grinding wheel and particularly exist in high speed ceramic emery wheel, there is provided that a kind of cost is lower, refractoriness is lower, the ceramic bond of high strength, effectively can improve the intensity of vitrified grinding wheel, turning spur speed, work-ing life, security and quality product.
Technical scheme of the present invention is: a kind of high-strength ceramic bonding agent, and each component of its formulation consists is made, and is by ratio of weight and the number of copies: feldspar 35 ~ 45 parts, clay 15 ~ 25 parts, boron glass 5 ~ 15 parts, wilkinite 5 ~ 15 parts, triphane 10 ~ 20 parts, 4 ~ 6 parts, quartz.
Further scheme is: described high-strength ceramic bonding agent, and each component of its formulation consists is made, and is by ratio of weight and the number of copies: feldspar 40 parts, clay 20 parts, boron glass 10 parts, wilkinite 10 parts, triphane 15 parts, 5 parts, quartz.
Concrete preparation method:
(1) by formulating of recipe, precise feldspar, clay, boron glass, wilkinite, triphane, quartz, add after mixing in ball mill and carry out ball milling.In ball mill, pellet weight ratio is 3:1, Ball-milling Time 30 minutes, crosses 80# screen cloth after discharging.
(2) calcine in above-mentioned compound loading High Temperature Furnaces Heating Apparatus, maximum sintering temperature is 1200 DEG C.
(3) bonding agent after calcining is added in ball mill and carries out ball milling.In ball mill, pellet weight ratio is 1:3, Ball-milling Time 120 minutes, crosses 320# screen cloth after discharging, i.e. obtained this kind of bonding agent.
The present invention adds the wilkinite of corresponding proportion in clay-feldspar-boron glass class bonding agent, because the performances such as bentonitic plasticity-, adsorptivity are close to clay, but its refractoriness only has 600 ~ 700 DEG C, well below the refractoriness of clay 1700 ~ 1780 DEG C, effectively reduce the overall refractoriness in conjunction with Liu, when high temperature burns till, reaction is more abundant.The introducing of triphane, as urging flux to impel formation glassy phase, improves the intensity of bonding agent, thus reaches the object improving the finished product intensity.The introducing of a small amount of quartz, can regulate the plasticity-of bonding agent, reduces dry shrinkage; When high temperature burns till, volume produces expansion simultaneously, and base substrate when can reduce high temperature shrinks.Of the present invention through mixture owing to having carried out high-temperature calcination in the preparation, in its various starting material, impurities greatly reduces, and improves high temperature wettability and the response capacity of bonding agent, to raising wheel strength have very great help.Utilize the bonding agent described in this invention, effectively can not only improve the intensity of high speed ceramic emery wheel, work-ing life, safety performance and conforming product rate etc.; During for the manufacture of conventional ceramic emery wheel, can also reduce the consumption of bonding agent, promote grinding efficiency and the ground effect of emery wheel, reduce manufacturing cost, economic benefit is fairly obvious.
