摘　　要：选取三种典型涂料用抗水剂,通过分析涂布后纸页的Cobb值、静态接触角、油墨吸收性能、拉毛速度等重要指标,研究了防水涂布纸涂料配方及纸张表面防水性能。确定最佳涂料配方。研究表明:底涂配方采用#2抗水剂且用量为0.5份,面涂涂料采用#1抗水剂且用量为7.5份时涂布纸具有良好的防水效果和表面性能。采用电子探针(EPMA)进行表面结构分析表明添加#1抗水剂在涂层表面形成了结构致密的防水涂层。Three typical kinds of waterproof agents were selected and subsequently applied as additives in paper coatings. The coating formula and the waterproof properties of coated paper were studied through analyzing the Cobb value, static contact angle, ink absorption properties and picking velocity. The results showed that the waterproof properties and surface properties can be reached when No.2 waterproof agent is applied at 0.5 pph in bottom coating colors and No.1 waterproof agent at 7.5 pph in top coating colors. Furthermore, EPMA results indicate that the tight waterproof layer was formed in the coating surface by adding No.1 waterproof agent.
