The invention relates to a method for evaluating the service life of paper, which is used for estimating the service life of the paper by using a paper sample artificial accelerated aging method, applying a molecular weight characterization technology of gel permeation chromatography and combining a Monte Carlo computer simulation technology. According to the Monte Carlo method, the defects of gel chromatography characterization can be made up, a kinetic model matched with a paper sample aging mechanism is adopted, molecular weight distribution of aging reaction system molecules is comprehensively provided, and the effectiveness of a paper service life estimation result is greatly improved; in addition, the method can predict the preservation time of the paper under a specific temperature condition, has small dependence on the environment, and can be popularized to other different laboratories. 本发明涉及一种纸张的寿命的评定方法，通过纸样人工加速老化方法，运用凝胶渗透色谱的分子量表征技术，联合蒙特卡洛计算机模拟技术预估纸张的寿命。本发明中蒙特卡洛方法能够弥补凝胶色谱表征的不足，采用与纸样老化机制吻合的动力学模型，全面提供老
