Abstract
The present invention provides a kind of nano-grade ceramic binding agent, belongs to machining technology field.Following technical scheme is provided, each component and constituent mass fraction are：40 50 parts of aluminum oxide, 30 40 parts of boron oxide, 10 20 parts of alkali metal oxide.Sintered 46 hours at 600 700 DEG C after above-mentioned raw materials are well mixed by mass fraction proportioning, obtain vitrified bond matrix.Nanometer grade silica is added in vitrified bond matrix again, sintered at 800 850 DEG C.The technical scheme that the present invention is provided, with sintering at a lower temperature with regard to the superiority of densification can be reached.Nano ceramics sintering temperature is about lower 400 600 DEG C than traditional crystal grain ceramics, and sintering process is also greatly shortened.
Description
Technical field
The present invention relates to a kind of nano-grade ceramic binding agent, belong to machining technology field.
Background technology
Vitrified bond is to apply a kind of increasingly extensive bonding agent at present, and its performance is between metallic bond and resin knot
Between mixture.Holding of the metallic bond to abrasive particle is preferable, and intensity is high, and toughness is preferable, but its self-sharpening is poor, stomata
Rate is low, and finishing is difficult, especially when processing metal material, easily occurs workpiece adhesion, burn and tool jams
Situation；Resinoid bond self-sharpening can be good, is not easily blocked, seldom finishing, and grinding efficiency is higher, grinding temperature compared with
It is low, and itself there is certain elasticity, polishing action, but its poor heat resistance can be played, what is produced in grinding process is big
The thermal capacitance of amount is easily caused resin softening or decomposed, and causes its cohesive force to decline, causes the abrasive material of costliness not sent out completely also
The effect of waving just largely comes off.But existing vitrified bond product quality is low, application effect is undesirable, and determines ceramics
The key of binding agent grinder performance is the performance of bonding agent.And the sintering temperature that the raising of bonding agent performance is required is higher,
But because the heat endurance of diamond is bad, in the case where temperature is higher than 800 DEG C, easily occur oxidation or graphitization etc.
Chemical reaction.
The content of the invention
The purpose of the present invention is that there is provided following technical scheme, each component and component to overcome above-mentioned the deficiencies in the prior art
Mass fraction is：40-50 parts of aluminum oxide, 30-40 parts of boron oxide, 10-20 parts of alkali metal oxide.By above-mentioned raw materials
Sintered 4-6 hours at 600-700 DEG C after being well mixed by mass fraction proportioning, obtain vitrified bond matrix.
Nanometer grade silica is added in vitrified bond matrix again, sintered at 800-850 DEG C.Described nanometer pottery
Porcelain bonding agent adds 20-30% water and 1-2% surfactant, and sintered body rupture strength is more than 100MPa.
The beneficial effects of the invention are as follows：It is an advantage of the invention that：The bonding agent is sintered using nano powder, densification
Speed is fast, sintering temperature is low, with sintering at a lower temperature with regard to the superiority of densification can be reached.Nano ceramics
Sintering temperature is about lower 400-600 DEG C than traditional crystal grain ceramics, and sintering process is also greatly shortened.
