| 摘 要： | 以玉米淀粉为原料，制备了不同羧基含量的氧化淀粉，并通过实验比较了不同羧基含量的氧化淀粉的表面施胶性能．结果表明，与高羧基含量的氧化淀粉相比，用羧基含量适中的氧化淀粉进行表面施胶不仅能提高纸张的抗张强度和环压强度，而且生产成本较低，表现出了更好的表面施胶性能．

| Abstract: | The oxidant starch was prepared by the reaction of corn starch with peroxide. The influencing factors of oxidant dosage, pH value, temperature, catalyst dosage were studied taking corn starch as material, peroxide as oxidant and method as orthogonal experiments. Further, the oxidized starch with different oxidation degree as surface sizing agent applied to corrugated medium, analyzes the effect of starch＇s oxidation degree on ring crush and tensile. The optimum conditions were. re（corn starch） ： m（oxidant dosage） = 100： 7,reaction temperature 55℃,pH=7. The carboxylic content of oxidized starch was 0. 478%. Comparing the surface sizing results of oxidized starch with high carboxylic content and low carbox- ylic content, the result showed that oxidized starch With low carboxylic content was a high effective surface sizing agent. |
