Abstract
The invention discloses a preparation method of iron oxide black for a polishing agent. The preparation method comprises the following steps: (1) uniformly mixing 1-2 parts of tung oil anhydride, 0.3-0.5 part of a silane coupling agent KH55O, 0.3-0.5 part of chitosan and 0.1-0.2 part of pulverized fuel ash, then adding 15-20 parts of ethylene glycol monobutyl ether, and uniformly stirring to obtain a modified solution for later use; and (2) adding 100-120 parts of iron oxide black to the modified solution, stirring for 1-2 hours at 1000-1200r/min, then adding 1-2 epoxy linseed oil and 0.2-0.4 part of polypropylene glycol diglycidyl ether, stirring at 800-1000r/min for 10-20 minutes at 30-40 DEG C, taking out, drying and grinding to obtain the iron oxide black.
Description
Technical field
The present invention relates to iron oxide black field, is exactly a kind of preparation method of the iron oxide black for rumbling compound.
Background technology
Z 250, chemical formula Fe
3o
4.Another name iron oxide black, magnet, magnet are the magnetic black crystals of tool, therefore be called again martial ethiops.Iron oxide black is widely used, yet its performance index are limited, is badly in need of customization at the specific breed of all directions.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of the iron oxide black for rumbling compound.
Above-mentioned purpose realizes by following scheme:
A kind of preparation method of the iron oxide black for rumbling compound, it is characterized in that: comprise the following steps: (1) is by 1-2 part tung oil acid anhydride, 0.3-0.5 part silane coupling agent KH55O, 0.3-0.5 part chitosan, after 0.1-0.2 part flyash mixes, add again 15-20 part ethylene glycol monobutyl ether, after stirring, obtain modification liquid standby;
(2) in modification liquid, add 100-120 part iron oxide black, under 1000-1200 rev/min, stir after 1-2 hour, add again 1-2 epoxy linseed oil, 0.2-0.4 part polypropylene glycol diglycidyl ether, at 30-40 ℃, 800-1000 rev/min after stirring reaction 10-20 minute, take out, dry, abrasive dust and get final product.
The preparation method of described a kind of iron oxide black for rumbling compound, is characterized in that: the stir speed (S.S.) of step (1) is 300-500 rev/min.
Beneficial effect of the present invention is: the present invention carries out modification to iron oxide black, makes it can obviously improve polishing effect.。
Embodiment
