Embodiment 1
[0020] See 1# in Table 1 for the raw material ratio of the damping laminate, see 1# in Table 2 for the raw material ratio of the bound laminate, and use polybutadiene hot-melt adhesive for the viscoelastic layer.
[0021] First, melt the asphalt at 120-160°C; secondly, add the filler, resin and rubber into the melted asphalt according to the weight ratio and stir evenly; extrude the green block with an extruder; finally, put the green block with a double roller Calender to make sheet
[0022] processing methods:
[0023] 1. Manufacturing process of damping laminates: According to the raw material ratio of 1# in Table 1, heat the asphalt at 160°C to melt, then add filler, resin and rubber to the melted asphalt, extrude and calender to make damping laminates, thickness 2mm.
[0024] 2. The production method of the binding layer:
[0025] Add the 1# raw material in Table 2 into the integrated machine, and adopt the equipment integrating rubber and plastic mixer-hoist-double-co...
