Description
Technical field
The present invention relates to superhard material and abrasive grinding field, provides and a kind of prepare nano-grade ceramic binding agent superhard material sand
The new method of wheel.
Background technique
Since superhard material (such as diamond, cubic boron nitride) to have that hardness is high, wearability is good, thermal stability is good etc. excellent
Point is widely applied in all kinds of grinding tools.In all kinds of ultrahard material grinding wheel bonds, metallic bond is from sharp
Property is poor, easily adheres when processing metal material, and resinoid bond thermal stability is poor, and vitrified bond is between metal knot
Between mixture and resinoid bond, heat resisting temperature is higher, self-sharpening is preferable, intensity is high, wearability is good.Ceramic bond super-hard
Material grinding wheel not only has that cutting is sharp, grinding force is small, high production efficiency, long service life, to be easy to shaping and dressing, grinding smart
Workpiece temperature is low when spending the advantages that high, but also having grinding, can eliminate residual tension and generate residual compressive stress, make workpiece
The characteristics of durability improves 30~50%.Therefore, the conduct of ceramic bond super-hard material grinding wheel is a kind of at a high speed, efficient, high-precision, low
The high-performance grinding tool product of cost, low pollution, becomes the research and development emphasis of world's grinding tool in recent years.
High-performance ceramic bonding agent is the key that prepare high-performance ceramic bonding agent extra hard material grinding wheel.With surpassing in recent years
The development of high speed extra hard material grinding wheel, to the performance of vitrified bond, more stringent requirements are proposed, that is, bonding agent is required to have height
Intensity, low refractoriness, good gas porosity, wellability, craftsmanship, chemical stability, and thermally expanded with superhard abrading agent and be
Number matching, however the defects such as the generally existing sintering temperature of traditional vitrified bond is high, intensity is low.Nano-grade ceramic binding agent due to
The advantages that its granularity is small, large specific surface area, sintering temperature is low, intensity is high, good toughness is expected to solve current traditional ceramics bonding agent
Contradictory problems between sintering temperature and low and high intensity improve the performance of ceramic bond super-hard material grinding wheel, further widen
The application range of extra hard material grinding wheel.
Recent domestic has carried out exploratory development to nano-grade ceramic binding agent.Compared with traditional vitrified bond, to the greatest extent
Pipe nano-grade ceramic binding agent has the advantages that intensity height, good toughness, sintering temperature are low etc., but since its granularity is smaller, specific surface area
Greatly, there are still some problems in the preparation process of extra hard material grinding wheel, is in particular in the following aspects: (1) due to receiving
The fine granularity and large surface area of rice vitrified bond, appearance is bulk, and density is lower, this may bring centainly the molding of grinding tool
Difficulty, green density and sintering strength are lower, shrink it is larger.(2) appearance is compared in nano-grade ceramic binding agent one pack system powder preparation
Easily, how to guarantee its favorable dispersibility during subsequent ball milling mixes and be uniformly distributed.(3) due to the activity of nano particle
It is higher, easily occur the abnormal growth of crystal grain in sintering process and be difficult to the disadvantages of densifying, therefore, to obtain truly
Nano ceramics structural material is not easy to.(4) compared with traditional ceramics bonding agent, to the structure of stomata in nano-grade ceramic binding agent
Relationship between (such as shape, content and size) and its performance lacks system in-depth study.
Based on the above analysis, if direct in-situ can generate nano-ceramic particle during preparation and be allowed to and superhard material
Material is built into the nano-grade ceramic binding agent extra hard material grinding wheel with ideal structure and performance, it would be possible to solve current nanometer pottery
The problem of porcelain bonding agent extra hard material grinding wheel preparation and application.
Summary of the invention
The object of the present invention is to provide a kind of methods that one-step method prepares nano-grade ceramic binding agent extra hard material grinding wheel.This hair
Bright preparation process is simple, and the requirement to equipment and process conditions is low, is conducive to promote and apply.
A kind of preparation method of nano-grade ceramic binding agent extra hard material grinding wheel, it is characterised in that preparation process includes following step
It is rapid:
