摘要
采用水溶液聚合法,以丙烯酸(AA)、丙烯酰胺(AM)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)为原料,合成了AA/AM/AMPS高吸湿性树脂,对其吸放湿性能进行了测试,分析了其吸放湿机理,发现该材料能够随着环境湿度的变化,自发且快速地吸湿放湿,在90%相对湿度(RH)下其平衡吸湿量可达2.19 g/g,且在吸湿48 h内即可达到1.04 g/g,其性能优于无机吸湿材料、部分文献所载高分子吸湿材料及前期制备的AA/AM高吸湿性树脂,可广泛应用于防潮及防腐蚀包装中。
By means of water solution polymerization, a high moisture absorptive resin is prepared by acrylic acid (AA) ,acrylamide (AM) and 2-aerylamido-2-methylpropanesuffonic acid (AMPS). This resin can absorb and release humidity quickly by itself with the environmental humidity changing. The maximum absorbency of this hygroscopic resin is 2. 19 g/g in 90% RH ,and its absorbency before 48 hours can reach 1.04 g/g. Its capability is better than inorganic hygroscopic material, and other polymer materials in some papers and our pre-prepared AA/AM high moisture absorptive resin. It can be widely used in moistureproof or anti-corrosion packaging.
