Abstract

The invention discloses a preparation method of special paper for a print. The preparation method comprises the following steps of: pulping clear water, paper mulberry bark pulp, wood pulp and an AKDsizing agent in a pulping machine, standing, and controlling water to obtain raw material pulp; enabling the weight ratio of the broussonetia papyrifera bark dry pulp to the wood pulp is 7-9: 1-3, andenabling the weight of the AKD sizing agent to be 0.2-0.5% of the weight of the broussonetia papyrifera bark dry pulp; and adding the raw material pulp into a papermaking tank to prepare pulp with the mass concentration of 12-17%, adding a first part of dispersing agent solution, stirring, adding a second part of dispersing agent solution, stirring to obtain papermaking pulp, carrying out papermaking manually, pressing paper and drying the paper, wherein the papermaking comprises three times of papermaking, papermaking pulp is splashed within 2 seconds after being beaten during the first timeof papermaking, the papermaking pulp is shaken for 20-25 times after being beaten and excessive papermaking pulp is splashed during the second time of papermaking, and during the third time of papermaking, an angle of 30 degrees is formed between the back surface of a papermaking device and the liquid level of the papermaking pulp, and the papermaking pulp is shaken for 20-25 times back and forth, shaken for 10-15 times left and right and then shaken for 20-25 times front and back.
