A balloon-type magnetorheological elastomer, preparation method and application of the present invention, each component comprises according to weight ratio: 100-150 parts of rubber matrix, 600-700 parts of magnetic particles, 16-25 parts of vulcanizing agent and 4 parts of accelerator ~5 parts, 20-30 parts of plasticizer, 30-50 parts of dispersant, 50-60 parts of compatibilizer, 10-20 parts of reinforcing agent, 10-30 parts of physical silica gel pore former, 10-30 parts of waterproofing agent share. Through the cooperation and coordination of each component, the elastomer not only improves the bond energy and compatibility between the magnetic particles and the matrix, but also improves the damping performance of the magnetorheological elastomer, and there are many airbags that are elastic and have good mechanical properties. . When an external magnetic field is applied to the balloon-type magnetorheological elastomer, its mechanical property response can be precisely controlled rapidly and reversibly. The airbag in the elastomer plays the role of active sound absorption and noise reduction control. Due to this unique magnetorheological behavior, the magnetorheological elastomer is suitable for promotion and use in the fields of vibration reduction, sound absorption and noise reduction. |
