Problems solved by technology

[0003] However, alum is easy to hydrolyze in a humid environment, and the acid produced after hydrolysis will accelerate the hydrolysis and aging of cellulose or silk fibroin, the main component in paper silk, making it difficult for ancient calligraphy and paintings to be preserved for a long time.

preparation example Construction

[0023] Such as figure 1 As shown, the preparation method of the anti-acidification type rice paper according to the embodiment of the present invention comprises the following preparation steps:

[0024] S1. Take deionized water, gelatin and alum as raw materials to prepare gelatin-based body fluid.

[0025] S2. Prepare a cross-linking mixed solution by using hydrolyzed protein, ethylene glycol diglycidyl ether and water as raw materials.

[0026] S3, using the cross-linking mixture as a matrix to add monomers to prepare a cross-linking matrix emulsion.

[0027] S4. Using magnesium oxide, water and sodium hydroxide as raw materials, mixing them to prepare anti-acidification modified particles.

[0028] S5. Take the gelatin base liquid, the cross-linked base emulsion and the anti-acidification modified particles, mix and homogeneously prepare a sizing agent.

[0029] S6, sizing the raw rice base, drying in the sun to prepare acid-resistant rice paper.

[0030] Thus, accordi...

Abstract

The invention provides a preparation method of acidification-resistant Xuan paper. The method includes firstly, preparing a gelatin-alum matrix liquid from deionized water, gelatin and alum; preparinga cross-linking mixed solution by taking hydrolyzed protein, ethylene glycol diglycidyl ether and water as raw materials; adding a monomer into the cross-linked mixed solution serving as a matrix toprepare a cross-linked matrix emulsion; mixing magnesium oxide, water and sodium hydroxide as raw materials to prepare acidification-resistant modifying particles; mixing the gelatin-alum matrix liquid, the cross-linked matrix emulsion and the acidification-resistant modifying particles, and homogenizing to prepare a sizing agent; performing sizing treatment on a Xuan paper matrix, airing and drying to obtain the acidification-resistant Xuan paper. The preparation method not only can effectively improve the color fastness of the Xuan paper in use, but also can reinforce cellulose in the Xuan paper material, so that the mechanical strength of the Xuan paper material is improved, and the storage period of the Xuan paper is prolonged.

Description

technical field [0001] The invention belongs to the technical field of rice paper preparation, in particular to a method for preparing acidification-resistant rice paper. Background technique [0002] Chinese ancient calligraphy and painting is an important traditional art category. There are a large number of ancient calligraphy and painting collections in various museums and folks in my country. Due to the large number of pores between paper or silk fibers, the carrier material of calligraphy and painting, it is easy to smudge and lose ink when writing and painting, which affects the effect of writing and painting. In order to improve the color fastness of paintings, it is necessary to use glue and alum to coat the pigment particles with glue, and then deposit them on the surface of paper fibers through alum. Alum, as a mordant, played a vital role in this process. In order to make their works more perfect, many meticulous painters will repeatedly dye alum water in the p...
