Problems solved by technology

[0007] Aiming at the problems that the existing technology cannot really recycle and treat the magnetorheological fluid modified by oleic acid, and there is secondary pollution, the present invention provides a magnetorheological fluid recovery treatment agent and its preparation method. The recovery treatment agent is mainly composed of lauryl alcohol Composed of polyoxyethylene ether, sodium hypochlorite, cyclooctadiene ruthenium dichloride and water, the oleic acid in the magnetorheological fluid is removed, so that the magnetorheological fluid loses the surfactant, resulting in the main dispersed particles in the magnetorheological fluid The bonding between the carrier liquids is eliminated, so that the main dispersed particles can settle rapidly under the action of their own gravity, so that the main dispersed particles and the carrier liquid are separated, which provides a basis for the subsequent recycling of magnetorheological fluids

Abstract

The invention discloses a magnetorheological fluid recovery treating agent and a preparation method thereof, and belongs to the field of magnetic waste liquid recovery treatment. The recovery treating agent disclosed by the invention is prepared from the following components in percentages by weight: 2 to 4 percent of dodecyl polyoxyethylene ether, 35 to 45 percent of sodium hypochlorite, 2 to 4 percent of cyclooctadiene ruthenium dichloride and the balance of water. Oleic acid in a magnetorheological fluid is removed through oxidative cracking by using sodium hypochlorite, so that the magnetorheological fluid is used for losing a surface active agent to cause that a cementing action between main dispersion particles and a carrier liquid in the magnetorheological fluid is eliminated; therefore, the main dispersion particles can quickly settle under the effect of gravity, the main dispersion particles are separated from the carrier liquid, and a foundation is provided for subsequent recycling of the magnetorheological fluid; and the magnetorheological fluid recovery treating agent has the advantages of simple components, simple preparation and low cost, and is simple in reaction condition and good in treatment effect when the magnetorheological fluid is treated.

Description

technical field [0001] The invention belongs to the field of magnetic waste liquid recovery and treatment, and more specifically relates to a magnetorheological fluid recovery treatment agent and a preparation method thereof. Background technique [0002] Magnetorheological fluid has been widely valued for its unique magnetorheological effect. Magnetorheological fluid is a suspension formed by distributing micron-scale ferromagnetic particles in a non-magnetic liquid. Under the action of an external magnetic field, the properties of the magnetorheological fluid (such as rheology, magnetism, mechanics, heat, optics, etc.) change rapidly, from the original viscous flow state to a solid state, and has a certain yield shear stress. The response time of the magnetorheological effect is very short, generally on the order of milliseconds, and the conversion between solid and liquid states is reversible. Once the external magnetic field is removed, the fluidity can be restored. T...
