Embodiment 1
[0013] Example 1. The damping soft board is prepared according to the following raw material proportions by weight: 48 parts of asphalt as base material, 20 parts of waste rubber powder, 24 parts of mud powder and 5 parts of fine sand as filler, 3 parts of polypropylene It is a temperature-resistant additive; the tire base is made of glass fiber cloth. It is extruded by heating and stirring machinery; a layer of fireproof film can be laid on the surface.
[0014] It is used to control the vibration of the fan pipeline and reduce the noise of the pipeline; when in use, just heat one surface of the damping soft plate and wrap it on the pipeline. It is used to control the vibration of the thin wall of the machine (such as a noodle making machine) and the wall of the sound insulation cover to reduce noise; when in use, just heat one side of the damping soft plate and stick it to the vibrating plate or the cover wall. It is used in floor vibration control to reduce the noise in t...
