In said structure, described antistatic layer thickness is 0.2 ~ 0.4 mm.
In said structure, described antistatic, fire-retardant composite bed thickness is 0.6 ~ 0.8 mm.
In said structure, described antistatic layer is UV antistatic coating.
In said structure, described bonding resin layer, bonding resin layer are the polyethylene polymer of maleic anhydride and tackifying resin modification.
In said structure, described flame-retardant layer is made up of following material (mass percent): polyethylene resin 75 ~ 80%, environmental protection fire retarding agent 20 ~ 25%.
In said structure, described antistatic, fire-retardant composite bed is made up of following material (mass percent): polyethylene resin 75 ~ 80%, environmental protection fire retarding agent 15 ~ 20%, the antistatic carbon black 5 ~ 8% of superconduction.
The present invention compared with prior art, has following good effect:
1. be provided with inside and outside two-layer antistatic layer, flame-retardant layer, make the present invention possess antistatic, flame retardant property preferably, electrostatic layer, flame-retardant layer do not affect mechanical property of the present invention.
