Abstract
The invention discloses a cerium based abrasive material, which contains a curing prevention agent used for softening the sediment of abrasive material grains when the abrasive material is dispersed into a medium and a dispersing agent for making the abrasive material grains disperse in a dispersion medium. Specifically, the content of the curing prevention agent is 0.02%-2.0% (weight ratio), and the content of the dispersing agent is 0.02%-2.0% (weight ratio). In all rare earth oxides, cerium oxide accounts for 40.0%-99.5% (mass ratio), and lanthanum oxide accounts for 0.5%-60.0% (mass ratio). According to the invention, the abrasive material grains have good dispersibility, the grain sediment has reduced hardness, and the abrasive efficiency is stably improved.
Description
Technical field
The present invention relates to a kind of abrasive substance, relate in particular to a kind of cerium based abrasive material.
Background technology
At present, for the abrasive substance that the surface of glass material is processed, conventionally can form being scattered in dispersion medium (such as water) under the state of slurries and use.And in the time that this slurries leave standstill, be easy to separate with dispersion medium as the abrasive substance abrasive particle of dispersion, produce deposited phenomenon.The precipitation separation of this abrasive particle not only can not maintain composition or the concentration of the given concentration slurries during recycling, thereby reduction mill efficiency, also, in the time of the hardening of abrasive particle throw out, glass surface easily adheres to abrasive particle, therefore need to eliminate from glass surface the operation of abrasive particle.In addition, in the time of the hardening of abrasive particle throw out, can cause that pore stops up, and causes being polished the generation of injurious surface mark.
Summary of the invention
therefore, the object of the present invention is to provide and a kind ofly can make abrasive substance abrasive particle favorable dispersity and make the sedimentary lower hardness of abrasive particle, and can make the stable abrasive substance improving of mill efficiency.
in order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
a kind of cerium based abrasive material, contains and solidifies preventing agent and dispersion agent; Wherein said curing preventing agent for making the throw out deliquescing of this abrasive substance abrasive particle in the time that described abrasive substance is distributed to medium, and described dispersion agent is used for making this abrasive substance abrasive particle to be dispersed in dispersion medium; The content that wherein solidifies preventing agent is 0.02% ~ 2.0%(weight ratio), the content of dispersion agent is 0.02% ~ 2.0%(weight ratio).
preferably, described curing preventing agent is selected from the one in crystalline cellulose, secondary calcium phosphate, sodiumβ-naphthalenesulfonate formaldehyde condensation products, synthetic silica.
preferably, described dispersion agent is selected from the one in Sodium hexametaphosphate 99 and trisodium phosphate.
preferably, all the cerium oxide proportion in rare earth oxide is 40.0% ~ 99.5%(mass ratio), lanthanum trioxide proportion is 0.5% ~ 60.0%(mass ratio).
owing to having adopted technical scheme as above, the present invention has following beneficial effect:
make abrasive substance abrasive particle favorable dispersity; Make the sedimentary lower hardness of abrasive particle; Make the stable raising of mill efficiency.
