With.In order to succeed application in above-mentioned field, these materials will generally pass through very delicate processing to obtain enough
High precision and superficial layer quality.Exactly because in this way, the processing for surrounding this kind of material both at home and abroad proposes various types of add
Work principle and processing technology.But since this kind of material has the characteristics that high rigidity and big brittleness, abrasive machining especially with
Fine-grained abrasive machining, which is still, realizes its precision machined main means.In terms of abrasive machining, using free abrasive
Processing is the main means for obtaining low roughness surface again.But for hard brittleness used in information and precision engineering field
Material, free abrasive grain processing is general to be difficult while obtaining high processing efficiency and high processing quality.Therefore, also have both at home and abroad very
More researchs are using concretion abrasive tool processes technique and the method being fixed on abrasive material in bonding agent.In these methods, resin
Or metal is widely used as combining agent material.It is typically all by abrasive grain and powdered combination using this two classes bonding agent tool
Agent material is made after being sintered by press molding after being pre-mixed.For this method of more coarse grained abrasive grain, there is no too many
Problem.But when the size of abrasive grain it is small to a certain extent when, the agglomerate effect of abrasive grain itself make abrasive grain be difficult in bonding agent
Even dispersion.Such tool is used to process the finished surface for being also difficult to obtain high quality.
Vitrified bond has the characteristics that heat-resisting, oil resistant, water-fast, resistance to acid and alkali is good, but existing vitrified bond material
Material consumption the energy it is larger, cannot get homogeneous bond material, also some can be made to be vapored away compared with the substance of low melting point, thus to its into
Row is effective modified, is the key that existing prepare in conjunction in place of agent material.
Invention content
The technical problems to be solved by the invention：For the problem that existing bonding agent material homogeneity is poor, provide

Obtain mixed liquor and in mass ratio 1:10, manganous fluoride is added in mixed liquor, is stirred and filters, filter cake is collected and vacuum is cold
It is lyophilized dry, collects to obtain modified particles；
（2）It counts in parts by weight, weighs 45~50 parts of 5% hydrochloric acid of mass fraction, 10~15 parts of zinc acetates, 6~8 parts of acetic acid respectively
Lithium and 1~2 part of boric acid are placed in beaker, are stirred and collect to obtain matrix liquid, then in mass ratio 1:8, absolute ethyl alcohol is added
Into ethyl orthosilicate, mixing is stirred at room temperature and adjusts pH to 5.5, obtains modification liquid；
（3）By volume 1:8, modification liquid is added dropwise in matrix liquid, after being added dropwise to complete, then crosslinking is stirred at room temperature, it is quiet
Gelation processing is set, desiccant gel and in mass ratio 1 is collected:5, modified particles are added in desiccant gel, are stirred simultaneously
It is placed in ball grinder, ball mill grinding simultaneously collects to obtain ball milling particle；
（4）Ball milling particle is placed in resistance furnace, heating heating and insulation reaction lead to nitrogen and exclude air, then in nitrogen atmosphere
Under, heating heating, heat preservation melts, and standing is cooled to room temperature, and is crushed and is ground up, sieved, you can is prepared into the uniform type and combines
Agent material.
Step（3）The modification liquid drop rate is 2~3mL/min.
Step（4）It is 35~40mL/min that the nitrogen, which is passed through rate,.
Step（4）The heat preservation melting temperature is 750~850 DEG C.
Compared with other methods, advantageous effects are the present invention：
Technical solution of the present invention uses modified glass powder to prepare uniformly modified combination agent material for raw material, high-purity by selecting
Raw material reduces influence of the impurity to material homogeneity energy, meanwhile, by the composition of uniform chemical constitution, it is made effectively to dissolve
And it is mutually compounded to form the glass material with rock-steady structure, simultaneously as corresponding combination occurs after persursor material melting,
Melting temperature is relatively low simultaneously, and the crystallization inside modified glass particle completely disappears, and effectively increases the uniform performance of material.
