Abstract

Abstract As a cultural carrier of historical inheritance, paper has high cultural, historical and scientific research value. But with the passage of time and the change of the environment, many paper are aging and damaged. In order to protect the paper, epoxy cyclohexane/chitosan/methyl methacrylate composite material for paper protection was synthesized by radical grafting polymerization with potassium persulfate (KPS) as initiator and disodium hydrogen phosphate (DSP) as buffer reagent. Through single factor experiment, the synthetic condition was obtained as follows: 3 g of monomer dosage, 7.5 mL of initiator, 80 °C of reaction temperature, 3 h of reaction time. The aging test showed that the coating material could obviously improve the mechanical properties and anti-aging properties of paper. The reversibility experiment shows that the composite material has certain reversibility. The acid and alkali salt resistance experiment shows that the coating material could effectively resist external acid and alkali corrosion and protect paper. This study provides some theoretical guidance for the protection of paper cultural relics.

环氧环己烷/壳聚糖/甲基丙烯酸甲酯复合材料的制备及应用

摘要论文作为历史传承的文化载体，具有较高的文化、历史和科学研究价值。但随着时间的推移和环境的变化，许多纸张都在老化和损坏。为了保护纸张，以过硫酸钾（KPS）为引发剂，磷酸氢二钠（DSP）为缓冲剂，通过自由基接枝聚合，合成了环氧环己烷/壳聚糖/甲基丙烯酸甲酯纸张保护复合材料。通过单因素实验，得到了合成条件如下： g单体用量，7.5 mL引发剂，80 反应温度°C，3 h的反应时间。老化试验表明，该涂料能明显改善纸张的力学性能和抗老化性能。可逆性实验表明，该复合材料具有一定的可逆性。耐酸碱耐盐实验表明，该涂料能有效地抵抗外界酸碱腐蚀，保护纸张。本研究为纸质文物的保护提供了一定的理论指导。
