Dampproof silence pad and preparation process thereof
The invention discloses a dampproof silence pad and a preparation process thereof. The preparation process comprises the following steps: mixing low density polyethylene and a hollow material and performing banburying to obtain semi-finished product particles A; mixing low density polyethylene, a foaming agent, an antioxidant and a coupling agent and performing banburying to obtain semi-finished product particles B; mixing low density polyethylene, a toughening agent and a lubricant and performing banburying to obtain semi-finished product particles C; mixing low density polyethylene and a coloring agent and performing banburying to obtain semi-finished product particles D; drying the semi-finished product particles A, B, C and D, stirring and mixing uniformly, and extruding into a sheet E by a single screw extruder; performing radiation crosslinking of the sheet E through a high-frequency high-voltage electron accelerator to obtain a foaming master slice F; preheating the master slice F by a horizontal foaming furnace, performing high-temperature foaming in a vertical foaming furnace, and sequentially performing the processes of calendering setting, corona, punching, trimming and coiling to obtain a coil of the dampproof silence pad; and performing thermal compounding between the coil G and PE films different in thickness on a compound machine with a heating device, and performing online slitting and coiling to obtain the dampproof silence pad.
