中文摘要:

      目的 赋予纸基材料甲醛吸附性能，提高其在甲醛去除领域的应用价值。方法 以对氨基苯甲酸钠改性的海泡石为原料，将其与研磨碳酸钙、丁苯胶乳、聚丙烯酸钠分散剂混合制备除甲醛涂料，并涂布在以废旧箱板纸为原料制备的纸张上，探究涂料配比和涂布量对涂布纸性能的影响。结果 当涂布量为18 g/m²时，制备的涂布纸物理性能最佳，与原纸相比，其抗张指数、耐破指数、环压指数分别提高了52.6%、60%、59.8%;采用改性海泡石占比70%的涂料制备的涂布纸甲醛的吸附量为226.75 μg/g。结论 以废旧箱板纸和改性海泡石为原料制备的涂布纸具有优异的甲醛吸附性能，为箱板纸在甲醛去除领域的应用提供了可能。

英文摘要:

      The work aims to endow paper-based material with formaldehyde adsorption performance to improve its application value in formaldehyde removal. The raw material, sodium p-aminobenzoate modified sepiolite was mixed with ground calcium carbonate, styrene-butadiene latex, and sodium polyacrylate dispersant to prepare formaldehyde removal paint, which was then applied to paper made from waste container board to investigate the effect of paint formulation and coating amount on the properties of coated paper. The results showed that when the coating amount was 18g/m2, the coated paper exhibited the best physical properties, with the tensile index, burst index, and ring crush index increasing by 52.6%, 60%, and 59.8% respectively compared with uncoated paper. The formaldehyde adsorption capacity of the coated paper prepared with paint containing 70% modified sepiolite was 226.75 ug/g. The coated paper prepared from waste container board and modified sepiolite demonstrates outstanding formaldehyde adsorption performance and physical properties.
