The invention relates to a production method of high-strength liner kraft cardboard paper. The production method of the high-strength liner kraft cardboard paper comprises the following steps of (1) producing raw wood pulp and recycled pulp respectively, sorting the recycled pulp into short-fiber pulp, medium-fiber pulp and long-fiber pulp, and conducting beating on the short-fiber pulp, the medium-fiber pulp and the long-fiber pulp through a pulping machine separately; (2) mixing the raw wood pulp and the medium-fiber pulp to obtain surface-layer pulp, mixing the long-fiber pulp and the medium-fiber pulp to obtain core-layer pulp, and mixing the long-fiber pulp and the short-fiber pulp to obtain bottom-layer pulp; and (3) making the surface-layer pulp, the core-layer pulp and the bottom-layer pulp flow into a surface-layer pulp headbox, a core-layer pulp headbox and a bottom-layer pulp headbox through a fan pump and a pressurized screen separately, sending the surface-layer pulp, thecore-layer pulp and the bottom-layer pulp into a screen part for screen part dehydration, and conducting squeezing shaping, sizing and crimping on the surface-layer pulp, the core-layer pulp and the bottom-layer pulp to obtain the high-strength liner kraft cardboard paper. The invention furthermore provides the high-strength liner kraft cardboard paper produced by adopting the method. A burst index and folding strength of the high-strength liner kraft cardboard paper produced through the production method are greatly improved compared with those of the prior art.
