Manufacturing method of DM single paper

The invention discloses a manufacturing method of DM single paper, which comprises the following steps: by using NBKP (blended with industrial hemp), LBKP and APMP as raw materials, sequentially and respectively pulping, proportioning, adding auxiliary materials, forming a wet paper sheet, pre-drying, coating and sizing, and post-drying to obtain the DM single paper; according to the bleached sulfate needlebush chemical pulp, a coating formula adopted for coating and sizing comprises the following components in parts by weight: 10-20 parts of Brazilian porcelain clay, 5-10 parts of aluminum oxide, 15-20 parts of talcum powder, 50-70 parts of coating-grade heavy calcium carbonate, 10-15 parts of styrene-butadiene latex and 0.1-0.2 part of a tricarboxylic acid copolymer. Experimental results show that the DM single paper surface glossiness, the printing glossiness and the surface strength are obviously improved, and the DM has high quality and low cost and is beneficial to application. 本发明公开了一种DM单纸的制造方法，包括以下步骤：
