| titleOfInvention | A kind of preparation method of loudspeaker magnetic fluid |
| abstract | A kind of preparation method of loudspeaker magnetic fluid, the present invention relates to the preparation methods of magnetic fluid.The technical issues of it is the volatility height that solve existing loudspeaker magnetic fluid, poor high temperature stability.The magnetic fluid is by nanometer Fe 3 O 4 , n-hexane, one-time surface dressing agent, secondary coating material, synthesis hydrocarbon base oil, antioxidant, viscosity modifier and antiaging agent be made；Preparation method are as follows: by Fe 3 O 4 It is added in n-hexane and reacts, after stratification, obtain the nanometer Fe on upper layer 3 O 4 Hexane solution；Then one-time surface dressing agent is added, then one-time surface modification is completed in temperature reaction；Synthesis hydrocarbon base oil mixed liquor is obtained after antioxidant, viscosity modifier high speed shear is added in synthesis hydrocarbon base oil；The nanometer Fe that one-time surface is modified 3 O 4 Mixed liquor is added in synthesis hydrocarbon base oil mixed liquor after reaction, adds antiaging agent and the reaction of secondary coating material, obtains loudspeaker magnetic fluid. |
