Description
Technical field
The present invention relates to chemical fields, and in particular to a kind of metal matrix diamond tool burns pressure graphite jig with carbon-based point
Type agent and preparation method thereof and application method.
Background technology
The realization of diamond abrasive industrialized production is known as the breakthrough with milestone significance acquired by Abrasive Industry
Property achievement, being machined into one and have ready conditions the epoch of high-efficiency and precision operation may be implemented from this material.Almost start to walk from this,
Various countries by high-efficiency and precision process for the purpose of each diamond-like concretion abrasive tool also begin to flourish.
And it is main to make metallic bond used in diamond abrasive tool to mostly use bronze, iron, cobalt, nickel alloy greatly
Bond material, used method are mostly sintering process.Basically the making of diamond tool is by powder forming and sintering
Two procedures composition, under special circumstances, forming process is not important, but sintering circuit or the high temperature work for being equivalent to sintering
Sequence is indispensable.Sintering is also last one of master operation of diamond tool production process, to the performance of final products
It plays a decisive role, because waste product caused by sintering can not be saved by subsequent handling, sintering plays " checking on " product quality
Effect.
But during burning pressure, due to burning pressure graphite jig used and the close contact of diamond abrasive tool, in high temperature
The metallic bond part of lower low melting point is melted, and is immersed in the slight void of graphite jig, be bonded with graphite jig generation, die sinking

Specific implementation mode
In order to make objects and advantages of the present invention be more clearly understood, the present invention is carried out with reference to embodiments further
It is described in detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to limit this hair
It is bright.
An embodiment of the present invention provides a kind of metal matrix diamond tool burn pressure the carbon-based parting compound of graphite jig, by with
The raw material of lower mass percent is prepared：
Carbon dust (graphite) 65%-70%；CaCO3Powder 20%-22%；Na2CO3Powder 2.5%-3.5%；MgCO3Powder 2.5%-
3.5%；Al2O3Powder 2.5%-3.0%；SiO2Powder 2.5%-3.0%；The sum of weight percent of each component is 100%, and carbon
Powder (graphite), CaCO3Powder, Na2CO3、MgCO3Powder, Al2O3Powder and SiO2The particle size range of powder is 0-40 μm.
The embodiment of the present invention additionally provides above-mentioned metal matrix diamond tool and burns the pressure carbon-based parting compound of graphite jig
Preparation method includes the following steps：
After each raw material being weighed by above-mentioned formula, ball milling mixing, you can obtain metal powder and burn pressure graphite jig with carbon-based point
Type agent.
Gained metal matrix diamond tool burns the application method of the pressure carbon-based parting compound of graphite jig, including walks as follows
Suddenly：
S1, by graphite mold surface deashing；
S2, carbon-based parting compound is taken uniformly to brush in graphite mold surface using banister brush is viscous；
S3, the sintering of metal matrix diamond tool；
S4, cooling parting；Then step S1-S4 is repeated.
This specific implementation has good electric conductivity (will not be to graphite jig and gold due to containing a large amount of carbon dust in formula
The electric conductivity belonged between carcass diamond tool has a negative impact), while its lubricity well makes graphite jig and diamond
Abrasive material tools have good separation property, eliminate fracture, deformation etc. that diamond tool occurs when without using carbon-based parting compound
Defect substantially increases the success rate of diamond abrasive tool making.Meanwhile metal matrix diamond tool burns pressure graphite jig
With carbon dust, the Na in carbon-based parting agent prescription2CO3Powder, MgCO3Powder, Al2O3Powder, SiO2Powder and CaCO3Powder is filled in graphite table
It in the slight void in face, does not react with graphite jig, does not also react with metallic bond, less occur with diamond
Reaction.Therefore stronger mechanical snap power will not be formed.
In this specific implementation each component there is it specifically to act on (carbon dust i.e. graphite-phase is led for other parting compounds
Electrically preferable and its heat-resisting quantity is good, simultaneously because its lubricity is good, makes graphite jig and diamond tool separation property very
It is good；Na2CO3Powder and MgCO3Powder have cementability, so that parting compound is preferably sticked to die surface, will not molding sintering before from
Graphite mold surface is fallen；CaCO3Powder keeps the parting compound being laid on graphite jig uniform, while and Al2O3Powder and SiO2Powder has
There is supporting role)
The particle size range of each component is 0-40 μm in this specific implementation formula, and the thickness that when use smears can arbitrarily regulate and control,
It need to only be selected according to working condition, and not influence the mouldability of diamond tool.
Carbon-based parting compound obtained by this specific implementation can be stored for a long time, make succinctly, only need parting compound each component according to the ratio
Ball milling mixing is carried out after weighing to be obtained, when use with banister brush by the carbon-based parting compound brushing prepared in graphite surface.
Metal matrix diamond tool provided by the invention burns back scattering Fig. 1 institutes of the pressure carbon-based parting compound of graphite jig
Show.
Fig. 2 is when not burning pressure slim diamond blade using carbon-based parting compound, and saw blade is adhered cross section with graphite jig
Microscopic appearance figure, the right black portions are graphite jigs, and left side light-colored part is metal matrix diamond ultra-thin saw blade.We
It can see graphite mold surface and rough from figure, internal not fine and close have crackle and gap.It is flowed when metal matrix high temperature
Property it is good, invade in graphite jig, form more close mechanical bond after cooling meat, can not parting take out saw blade, if by force
Open form processed can cause saw blade and burn failure.
Fig. 3 is saw blade and graphite jig in no burning pressure super thin metal carcass diamond saw blade using carbon-based parting compound
The pattern being adhered after fracture polishing.Intermediate light-colored part is super thin metal carcass diamond saw blade in figure, and both sides black portions are
Graphite jig.The metal of low melting point is molten in hot conditions part in metal matrix diamond saw blade as we can clearly see from the figure
Change, soaks in the minim gap of people's graphite jig to generate close mechanical bond with graphite jig.This phenomenon will lead to stone
Black mold can not open form take out saw blade, can mold damage and diamond saw blade if open form by force；Reduce metal matrix Buddha's warrior attendant
The production efficiency and economic benefit of lapicide's tool.
With specific function, (carbon dust, that is, graphite is with well during burning is molded for each component in this specific implementation
Electric conductivity, while its lubricity is good, electric conductivity have ensured the conductive heater burnt during pressure, lubricity be easy to graphite jig with
The separation of diamond tool；Na2CO3Powder and MgCO3Powder has preferable surface-active, and parting compound is enable preferably to be sticked to graphite
Die surface；CaCO3Powder can make parting compound powder evenly laid out in graphite mold surface, while and Al2O3Powder and SiO2Powder is being burnt
Pressure during play certain supporting role), so that graphite jig is detached with metal matrix diamond tool perfection, be not on
The fracture apperance in face.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can also make several improvements and retouch, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
