Problems solved by technology

[0005] The technical problem to be solved by the present invention is to use the traditional painting and calligraphy mounting paste, which is made from starch gelatinization. After long-term use, the calligraphy and painting works will be mildewed and moth-eaten, which shortens the preservation time of calligraphy and painting and affects its To preserve the quality of the problem, a gelatin extracted from pigskin reacts with gelatinized starch to improve the viscosity and film-forming properties of the gelatinized product. After reacting the modified gelatinized product with methyl acrylate and vinyl acetate The method for preparing the painting and calligraphy mounting paste. In the present invention, firstly, the pigskin is degreased with anhydrous ether and n-butanol after freezing, thawing and alkali soaking treatment, and after degreasing, it is dissolved with acid bubbles and filtered to obtain a viscous liquid. , then mix cornstarch with wood vinegar and other substances and heat to obtain gelatinized product, mix with viscous liquid and then ultrasonically treat to obtain modified gelatinized product, and finally react it with vinyl acetate and other substances to obtain moisture-proof and insect-proof calligraphy and painting mounting paste

Abstract

The invention relates to a preparation method of moistureproof and mothproof calligraphy and painting mounting paste and belongs to the technical field of preparation of paste. The preparation method comprises the following steps: firstly, carrying out freezing, unfreezing and alkali soaking treatments on pigskin, then degreasing the pigskin with absolute ether and n-butanol respectively, carrying out acid soaking dissolution after degreasing, filtering to obtain viscous liquid, then mixing substances including corn starch and pyroligneous, heating a mixture to obtain a paste substance, mixing the paste substance and the viscous liquid, carrying out ultrasonic treatment on a mixture to obtain an improved paste substance, and finally carrying out reaction on the improved paste substance and substances including vinyl acetate to obtain the moistureproof and mothproof calligraphy and painting mounting paste. The prepared moistureproof and mothproof calligraphy and painting mounting paste is excellent in moisture resistance and moth resistance without rotten due to insect bites within 2-3 years and mildews within 7-10 months, and the retention time is prolonged.

Description

technical field [0001] The invention relates to a method for preparing moisture-proof and insect-proof calligraphy and painting mounting paste, which belongs to the technical field of paste preparation. Background technique [0002] Paste is used as the adhesive between paper and paper, paper and mounting fabric in the painting and calligraphy mounting and restoration work. Painting and calligraphy mounting paste has a vital impact on the preservation and restoration of calligraphy and painting. The quality of mounting paste is directly related to the quality of the work and the preservation time of the work. The paste used in painting and calligraphy mounting and restoration should have good wettability, adhesion, film-forming property and reversibility, moderate viscosity, clean and mothproof. The quality of paste directly affects the quality of mounting and restoration. Paste is a key material in the entire mounting process and an important factor affecting the quality o...
