【摘要】 针对预油漆纸易受潮吸湿的问题 ,本文以三聚氰胺与尿素、甲醛共聚的改性浸渍树脂为对象 ,研究经过树脂浸渍后 ,预油漆纸的耐潮性能及影响因素。通过对浸渍纸恒温恒湿处理和定时观测 ,发现树脂中三聚氰胺与尿素的重量比为 1∶5时 ,耐潮性能显著提高 ;纸中浸胶量为 30 %和 5 0 %时 ,纸张的吸湿过程不同 ,高浸胶量的纸吸湿速度快 ;在不同的环境湿度下 ,浸渍纸的吸湿率随湿度提高而增加。文中还探讨了预油漆纸在不同湿度环境中的使用和储存对策更多还原

【Abstract】 This paper aimed at the problem of the finish foil being easily affected with damp, took the melamine modified urea formaldehyde resin as the research object, studied the anti-moisture performance and the influencing factors of the finish foil. In the experiment, it found through the same temperature and moisture treatment and observation at definite-time, when the ratio of the melamine to urea of the resin is 1∶5,the anti-moisture performance is improved drastically; when the amount of the impregnation glue is 30% and 50% respectively, the process of absorbing moisture is different, the absorbing moisture velocity of the paper of high amount of the impregnation glue is fast; in different environmental moisture, the absorbing moisture ratio increased with the moisture improved. This paper also discussed the countermeasure when the finish foil uses and stores in different moisture environment.更多还原
