[0003]
Liquid damping materials generally need to be sealed because of their fluidity, so the use requirements are very high, resulting in a limited range of use, and a single liquid damping material is easy to introduce impurities during use, resulting in use effects, damping The effect becomes worse. With the prolongation of use time, more and more impurities will cause the noise of the damping material to increase during use.

Abstract
The invention discloses a liquid damping and denoising material and a preparation method thereof, and belongs to the field of damping materials. The liquid damping and denoising material and the preparation method thereof have the advantages that an external pseudo-solid layer is broken due to stress deformation before and after use of the material to achieve a certain damping effect; after the external pseudo-solid layer is broken, the liquid damping material is activated, softened and turned from a solid to a fluid to be used normally, embedded wires penetrate among small fragments, and thesmall fragments are bound in the surface of a lining skeleton layer under the action of an adhesive layer; as the hours of use become longer, the small fragments of the external pseudo-solid layer become smaller and smaller to finally appear almost powdery, and have better protection effect on the surface of the lining skeleton layer; the powdery external pseudo-solid layer has better sound-absorbing ability than solid one; the liquid damping material has better sound-absorbing and denoising ability than damping materials with big noise in the prior art.
Description
technical field [0001] The invention relates to the field of damping materials, in particular to a liquid damping and noise reduction material and a preparation method thereof. Background technique [0002] Liquid damping materials generally include damping oil, also called resistance oil, shock absorbing oil, high-viscosity lubricating oil, damping lubricating grease, high resistance lubricating oil, damping lubricating oil, shockproof oil, which is composed of high-purity inorganic thickener and special synthetic A new type of high-quality wide-temperature lubricating oil for damping, buffering, and sealing. It is used in the damper. Only when the damping oil changes with the temperature in any environment and its performance is stable can the damper achieve a perfect damping effect. . Widely used in knobs, shafts and various positioning mechanisms of home appliances, electronics, toys, and optical instruments. It is non-toxic and meets the requirements of environmental p...
