Abstract

The invention belongs to the technical field of high-molecular polymer synthesis, relates to preparation of a polymer material for paper cultural relic protection, in particular to a preparation method of the polymer material for paper cultural relic protection and application thereof. The preparation method of the polymer material for paper cultural relic protection comprises the steps that modified cellulose (MCC) and modified TiO2 serve as cores, styrene-acrylate copolymer serves as a shell, and a composite emulsion with a core-shell structure is obtained. According to the preparation method of the polymer material for paper cultural relic protection, the obtained protective material is good in stability and small in surface tension, and the excellent performance of water proofing, grease proofing, water resistance, acid and alkali resistance, bacterium resistance, reversibility and the like is achieved; the preparation technology is simple, operation is easy and convenient, applied solvent adopts water, pollution does not exist, and green and environmental protection are achieved. The polymer material and paper cultural relics have better compatibility, the thickness is ultra small, the transparency is good, the original appearance of the paper cultural relics is not affected, the principle of restoring the old as the old is followed, the reversibility is achieved, and a protective film can be removed.

Description

technical field [0001] The invention belongs to the technical field of polymer synthesis, and relates to the preparation of a polymer material for paper cultural relic protection, in particular to a preparation method and application of a polymer material for paper cultural relic protection. Background technique [0002] Papermaking is one of the four great inventions of my country. Paper first originated in the late Western Han Dynasty. It recorded the social and historical changes, the progress of human civilization, and the development of science and technology at that time. However, with the passage of time, paper cultural relics carrying social memory are constantly aging and damaged. There are tens of thousands of paper cultural relics, and the number of Ganges sands, but their aging speed is also amazing. According to statistics, according to the calculation of "the average annual damage rate of paper cultural relics in national collections is 1.33‰", tens of thousa...
