Novel environment-friendly high-barrier direct plating paper and preparation process thereof

The invention relates to novel environment-friendly high-barrier direct plating paper and a preparation process thereof. The direct plating paper sequentially comprises a back coating, a raw paper layer, a bottom coating, an aluminum plating layer and a surface coating from bottom to top, wherein the back coating is a water-based coating coated on the back surface of raw paper, the bottom coatingand the surface coating are EB cured coatings, and the aluminum plating layer is a metal aluminum layer plated on a bottom coating barrier layer in a vacuum evaporation manner and having a preset thickness. The production process is characterized by comprising the following steps: (1) coating base paper with a primer; (2) carrying out electron beam radiation curing to form a prime coat barrier layer; (3) carrying out vacuum evaporation aluminizing to increase the thickness of an aluminum layer so as to form an aluminized layer; 4) coating the aluminized layer with a surface coating material; (5) carrying out electron
