The utility model is achieved by the following specific technical means:

an industrial composite plastic film comprises a reinforcing layer, a base layer, an antistatic layer and an outer surface layer; a reinforcing layer is arranged in the middle of the base layer; the antistatic layers are fixedly bonded and connected with the base layer through an adhesive; the two sides of the antistatic layer are provided with outer surface layers which are fixedly bonded and connected with the antistatic layer through an adhesive; the base layer is made of high-density polyethylene; the high-density polyethylene has excellent hardness and tensile strength; the antistatic layer is made of biaxially oriented polystyrene; the biaxially oriented polystyrene has good insulating property and high barrier property, and is nontoxic and odorless; the outer surface layer is made of polyether TPU; the TPU film has the characteristics of wide hardness range, high mechanical strength, outstanding cold resistance, good processability, oil resistance, water resistance, corrosion resistance, good recycling property and the like; a plurality of convex wear-resistant salient points are uniformly arranged on the outer side of the outer surface layer.

Further, the reinforcing layer is a metal grid layer formed by transversely and longitudinally interweaving metal wires; the metal mesh with the mesh structure has stronger tensile property and strength and excellent puncture resistance.

Furthermore, the wear-resistant salient points are made of polytetrafluoroethylene materials; the polytetrafluoroethylene has the characteristic of extremely low friction coefficient, and improves the wear resistance of the two sides of the plastic film, thereby prolonging the service life of the plastic film.

Compared with the prior art, the utility model has the following beneficial effects:

the utility model improves the stretch resistance and puncture resistance of the plastic film and avoids the puncture by sharp objects; meanwhile, the wear-resistant alloy has good wear resistance and high corrosion resistance, and has the effect of preventing wear or corrosion.
