| Abstract:In this study， typical paper documents of different ages were taken as the research objects， and the physical and chemical properties and preparation process of paper literature were tested and analyzed to copy the deacidification test paper which could be used as a substitute for paper literature. The effects of accelerated aging process on the tightness， mechanical properties， and degree of cellulose polymerization of deacidification test paper were studied to assess the feasibility of deacidification test paper for replacing paper literature of different years. The results showed that deacidification test paper could be copied by acid sizing with rosin （2% dosage） using talc （10% dosage） as filler. The degradation kinetics study found that the degree of cellulose polymerization of the deacidification test paper had an obvious correlation with the aging time， and the R2 was 0.96. In addition， the multivariate linear fitting found that the mechanical properties of the deacidification test paper had an obvious correlation with the tightness and degree of cellulose polymerization and the R2 reached 0.99， and the tensile index and the degree of cellulose polymerization of the aged deacidification test paper basically remained the same as that of the paper of different ages， which indicated that the deacidification test paper could be used to replace different generations of paper. |
