| titleOfInvention | A stable and fast response high yield strength bimodal magnetorheological fluid and preparation method thereof |
| abstract | The invention belongs to the field of intelligent materials, and relates to a magnetorheological fluid with rapid response to high yield strength soft settlement and a preparation method thereof. The magnetorheological fluid provided by the present invention includes: composite magnetic particles, wherein the composite magnetic particles include bimodal carbonyl iron powders with different particle sizes, and the particle sizes of the bimodal carbonyl iron powders with different particle sizes differ by 3 to 300 times; The synthetic oil-based compound carrier liquid is added with a friction reducing and anti-wear agent, a thixotropic agent, an antioxidant and a surfactant. Also provided is a method for preparing a magnetorheological fluid, which comprises stirring and emulsifying composite magnetic particles and the synthetic oil-based composite carrier fluid to obtain the magnetorheological fluid. The yield strength of the magnetorheological fluid provided by the invention is greater than 80 MPa, and the response time is short and the settlement rate is low, and is suitable for aerospace, aircraft carrier, automobile engineering, mechanical engineering, and especially the fields that need to provide strong impact resistance. |
