Method.
Background technology
The material of traditional stone part is usually abrasive material, bonding agent and filler.Amount of filler according to its purposes have compared with
Big difference, generally 5-15%.Although the content of filler is relatively low, some components in filler in emery wheel process to generating
Stomata have vital effect, eventually affect the cutting performance and service life of emery wheel.In the manufacturing process of emery wheel
Suitable filler is added in, the formation of stomata can be increased, for storage coolant and cutting object, is improved from sharp effect and grinding
Efficiency.Existing process is used as pore-forming material using refined naphthalene, DMT, walnut capsomere etc..Refined naphthalene is molecular crystalline, and compressive resistance is low,
And it is toxic, it has been eliminated.DMT as a kind of new nano polycrystal composite material, have pore-forming uniformly, compressive resistance
High and nontoxic advantage, but the problem of secondary pollution is formed in process there are easy mechanical deformation, after volatilization.Core
The biological materials such as peach capsomere, there is no problem above, derive from a wealth of sources and cheap, but are limited by its molecular composition, easily
Water absorption and swelling causes emery wheel disqualification rate to increase, therefore is not appropriate for using directly as filler.
The present invention selects raw material of the hard biomass as pore-forming material, by changing its composition and physico-chemical property, with full
Requirement of the sufficient emery wheel process to pore-forming material.For example, its hydrophobicity can be improved, play moisture-proof, waterproof, acid-proof, alkali prevention,
The effects that easily scattered, reduces moisture and oxygen etc. to emery wheel internal penetration.In addition, it can also reduce machinery in process
Deformation improves binding agent to the hold of abrasive surface, makes molding mass more stable, loose, uniform indirectly.
The content of the invention
The object of the present invention is to provide a kind of emery wheel preparation methods of biomass-based dewatering filling, solve current emery wheel
In process pore-forming material there are the defects of, using hard biomass as initial material, by changing its structure composition and table
Face hydrophobic property improves its hydrophobic performance, avoids water absorption and swelling, reduces mechanical deformation, meets emery wheel processing to pore-forming material
It is required that.
