提要：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

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份方。研究表明：底涂配方采用＃２

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。关键词：防水剂；涂料配方；涂层；　静态接触角

Abstract: Three typical kinds of waterproof agents were selected and subsequently applied as additives in papercoatings. The coating formula and the waterproof properties of coated paper were studied through analyzing the Cobbvalue, static contact angle, ink absorption properties and picking velocity. The results showed that the waterproofproperties and surface properties can be reached when No.2 waterproof agent is applied at 0.5 pph in bottom coatingcolors and No.1 waterproof agent at 7.5 pph in top coating colors. Furthermore, EPMA results indicate that the tightwaterproof layer was formed in the coating surface by adding No.1 waterproof agent.Key words：　waterproof agents; coating formula; coating layer; static contact angle
