| 摘 要： | 研究了涂料体系中抗水剂的种类和用量对低定量、高吸收性原纸涂布后主要性能的影响。结果表明，Y（改性的丙烯酸酯共聚物）抗水剂、D（丙烯酸类聚合物）、X（苯乙烯-丙烯酸树脂类）和K（三聚氰胺甲醛树脂）等4种抗水剂对涂布纸的抗液体性能、湿拉毛强度和光学性能等影响差异很大，2％～4％用量的Y抗水剂作用时，涂布纸的Cobb值、K＆N值和湿拉毛强度等指标较为均衡，有一定的湿排斥现象，但对涂布纸IS0白度和不透明度影响不大。

| Abstract: | The influences of the species and added amount of water-resistance agents on the properties of coated high absorptive base paper with low basis weight were investigated. The four different water-resistance agents Y （modified acrylate copolymer）, D（ acrylic polymer）, X（ styrene-acrylic resin） and K（ melamine formaldehyde resin） , exhibit different effects on the liquid-resistance and wet-surface strength of the coated paper. When 2%-4% of Y are used, the wet-surface strength, Cobb value and K＆N value can be balanced on their higher levels with only light wet-resistance phenomenon, while the ISO brightness and opacity of the coated paper are not changed significantly. |
