The invention relates to a production process of low-basis-weight damp-proof waterproof coveying paper, which belongs to the technical field of the preparation of gypsum board coveing paper, and can solve the problems in the prior art that the performance of the gypsum board coveing paper is influenced and the cost is high due to the addition of additives in the gypsum board coveing paper production process. The production process comprises two steps, i.e. pulping and papermaking, wherein in a papermaking OCC production line, a process for pulping short fibers at a high concentration is adopted, the papermaking adopts four-layer mesh composite molding, deinked pulp is smeared on a surface layer, four layers of pulp are injected onto a four-layer molding mesh by virtue of a pulp flowing box, then the pulp is subjected to one vacuum pressing, twice large-roller pressing, primary drying, surface gluing, later drying and winding, and finally the pulp is rewound into paper rolls with different specifications by virtue of a rewinding machine. The production process saves the energy, reduces the pollution, improves the paper strength, reduces the basis weight of the paper, and improves the damp-proof and waterproof characteristics of the paper.
