[0002] The waterproof effect of the sound insulation pads in the prior art is relatively poor. The reason is that the sound insulation materials currently used are all soft and porous materials, which are easy to absorb moisture and water. In the construction process, even if a waterproof plastic film is used, due to the The nodes only take measures such as sealant, the waterproof effect is poor, and there is a slight negligence.
