| description | The invention discloses a preparation method of cultural paper, which comprises the following steps: adding a fiber swelling agent into fully-bleached sulfate broadleaf wood chemical pulp, and pulping until the beating degree is 24-28 degrees SR to obtain pulp; making the pulp into wet paper sheets, pre-drying the wet paper sheets, coating and sizing the wet paper sheets by using a composite sizing agent, post-drying the wet paper sheets, and calendering the wet paper sheets to obtain the cultural paper. Wherein the composite sizing agent is prepared from enzymatic conversion starch, nano cellulose and nano zinc oxide. The invention further provides the cultural paper. The cultural paper produced by the method provided by the invention belongs to a non-pigment-coated cultural paper product, the paper is loose and thick, the color and luster are elegant, the paper surface is fine and smooth, the paper is free of peculiar smell, large-ink-position printing is uniform and the luster is moderate during color prin |
