乳胶组合物及应用其的纸张
摘要：
本发明提供一种乳胶组合物，其含有环氧基官能聚合物、环氧基反应性聚合物及适量的水，其中环氧基官能聚合物的质量为环氧基反应性聚合物质量的5%~100%；该环氧基官能聚合物指含有环氧基的聚合物，具体包括水溶性聚官能环氧树脂、环氧基-改性的有机反应性硅酮、缩水甘油基环氧树脂、脂肪族非缩水甘油基环氧树脂、环脂肪族非缩水甘油基环氧树脂；该环氧基反应性聚合物为含有羧基、羟基、巯基、酐、胺、酰胺、氰基、酯基中的至少一种官能基团的聚合物。本发明还提供一种应用该乳胶组合物的纸张。本发明的纸张具有高湿强及湿抗压性，经低温固化，纸张的湿干比可提升至45%以上。
摘要（英）：

The invention provides a latex composition which comprises an epoxy-based functional polymer, an epoxy-based reactive polymer and a proper amount of water, wherein the mass of the epoxy-based reactive polymer is 5-100 percent of the mass of the epoxy-based reactive polymer; the epoxy-based reactive polymer comprises an epoxy-based polymer and specifically comprises water-soluble polyfunctional epoxy resin, epoxy-based-modified organic reactive silicone, glycidol epoxy resin, aliphatic non-glycidyl epoxy resin and cycloaliphatic non-glycidyl epoxy resin; and the epoxy-based reactive polymer is a polymer containing at least one functional group of carboxyl, hydroxyl, hydrosulphonyl, anhydride, amine, amide, cyano group and ester group. The invention further provides paper applying the latex composition. The paper disclosed by the invention has high wet strength and wet press resistance; and after the paper is cured at low temperature, the ratio of wetness to dryness can be improved over 45 percent.
