合成表面施胶剂在双胶纸中的应用

介绍了自制合成表面施胶剂的合成方法，并与市售合成表面施胶剂在实验室和纸机上进行了双胶纸施胶效果对比，结果表明：合成表面施胶剂加入后能提高纸页的表面强度，改善成纸的吸水性能，降低生产成本；与市售表面施胶剂比较，自制合成表面施胶剂在效果和成本上都有明显的优势。

The application of synthetic surface sizing agent in offset printing paper

The synthesis method of self-made surface sizing agent was introduced in this paper, comparisons of offset paper sizing effect were made between the self-made surface sizing agent and that on the market in laboratory and paper machine. The results indicate that synthetic surface sizing agent improves surface strength of paper and water adsorptivity of the finished paper so as to reduce the production cost. Compared with that on market, the self-made surface sizing agent has evident advantages in both effect and cost.
