Embodiment 1

[0019] Embodiment 1: Dongba paper of the present invention is prepared by the following method:

[0020] 1) Raw material preparation: 8 parts of bark and 1 part of chamaejasma root bark;

[0021] 2) Peeling: Soak the bark in water until soft, peel off the black bark and white bark with a knife, leave the white bark for later use, and peel off the bark at the root of the chamaejasma tree;

[0022] 3) Soaking: Soaking the bark in a 10% aqueous solution of sodium hydroxide removes lignin and other colloids and has a floating effect;

[0023] 4) Steaming: steaming in a steamer for about 72 hours;

[0024] 5) Rinse: Rinse in running water for a week;

[0025] 6) Bark stacking: step on the bark first with artificial feet, after cleaning, add 3% sodium hydroxide aqueous solution to soak and stack for about a week.

[0026] 7) Secondary cooking: cooking for about 72 hours;

[0027] 8) Reinforcement removal: After rinsing in clean water, manually remove the hard wood tendons in the...

Embodiment 2

[0032] Embodiment 2: also can prepare by following method:

[0033] 1) Preparation of materials: 10 parts of bark and 2 parts of chamaejasba root bark:

[0034] 2) same as embodiment 1;

[0035] 3) Soaking: Soaking the bark in a 15% sodium hydroxide aqueous solution removes lignin and other colloids and has a floating effect;

[0036] 4), 5) are identical with embodiment 1;

[0037] 6) Bark stacking: step on the bark first with artificial feet, after cleaning, add 6% sodium hydroxide aqueous solution to soak and stack for about a week.

[0038] 7), 8), 9) are identical with embodiment 1;

[0039] 10) Mixing: mix the above two raw materials for beating or pounding, add 60 parts of water, and mix well with each other, and add 1.5% cactus juice as lubricant;

[0040] The following steps are the same as in Example 1.

Abstract

A technology for making the Dongba paper of Naxi nationality with the paper mulberry bark and euphorbia root bark through proportioning, immersing in aqueous solution of sodium hydroxide, digestion, rinsing, adding aqueous solution of sodium hydroxide, stacking, digestion, removing hard wood, beating, mixing, shaping and drying in sun. Its advantages are high quality and preventing worm-eating.

Description

technical field [0001] The invention relates to papermaking technology, in particular to Naxi Dongba paper and a preparation method thereof. Background technique [0002] The Naxi Dongba paper produced by the Naxi people in Lijiang, Yunnan Province with traditional techniques, has the characteristics that it will not turn yellow and become brittle after long-term storage, and is easy to preserve for a long time. The Naxi people used it to record Dongba scriptures, and it is still used today. However, due to the rough and backward craftsmanship of Dongba paper made by traditional crafts, the paper has fine particles and cannot be printed by machine, which greatly restricts the use of Dongba paper with a simple style, and its production cost is also relatively high. high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, promote national culture, and provide a kind of Naxi Dongba paper which has the sim...
