Beschreibung
Zusammenfassung:The invention discloses a preparation method of a difunctional magnetorheological damping material, which comprises the following steps: step 1, weighing polyborosiloxane and dimethyl silicone oil according to a certain mass ratio, and uniformly mixing at a certain temperature; 2, uniformly mixing and stirring the mixture obtained in the step 1 and the compatilizer according to a certain proportion; 3, uniformly mixing and stirring the mixture obtained in the step 2 and a plasticizer according to a certain proportion; and 4, uniformly stirring and mixing the mixture obtained in the step 3 with ferromagnetic particles according to a certain ratio to obtain the difunctional magnetorheological damping material. The anti-settling performance and the anti-wear performance of the material are superior to those of a traditional magnetorheological fluid, and the excellent damping performance can still be kept under the state of no magnetic field. 本发明公开了一种双功能磁流变阻尼材料的制备方法,步骤如下:步骤一:称取一定质量比的聚硼硅氧烷、二甲基硅油,在一定温度下混合均匀;步骤二:取步骤
