摘　　要：目的为赋予医用涂胶透析盖材纸高强度高透气度,提高其在医疗包装领域的应用价值。方法研究了干燥温度、干燥时间及隔离胶与致孔剂的配比等工艺对涂胶纸透气性能、强度性能和表面性能的影响。结果在干燥温度85℃、干燥时间15 min、致孔剂加入量7%(涂胶量约2.0 g/m^(2))时,复合隔离胶纸透气度、横向抗张指数、纵向抗张指数、横向撕裂指数、纵向撕裂指数分别为280mL/min、60.00N·m/g、97.30N·m/g、8.52mN·m^(2)/g、8.06mN·m^(2)/g,涂隔离胶后透气度>200mL/min,涂热熔胶后透气度>80mL/min。结论通过对涂胶层的构筑及工艺优化,所制备的涂胶透析盖材纸具有优异的透气性能,为高强度高透气度医用涂胶透析盖材纸工艺提供了理论基础。The work aims to improve the strength and permeability of medical coated dialysis cover paper,and enhance its application value in the field of medical packaging.The effects of drying temperature,drying time and the ratio of isolation coating and pore-forming agent on the air permeability,strength and surface properties of coated paper were studied.The results showed that when the drying temperature was 85℃ and the drying time was 15 minutes,the addition amount of pore-forming agent was 7%(the coating amount was about 2.0 g/m^(2)),the permeability,transverse tensile index,longitudinal tensile index,transverse tear index and longitudinal tear index of composite insulating coated paper were 280 mL/min,60.00 N·m/g,97.30 N·m/g,8.52 mN·m^(2)/g,and 8.06 mN·m^(2)/g,respectively.The permeability was greater than 200 mL/min after application of isolation coating and greater than 80 mL/min after application of hot melt coating.In conclusion,through the construction of the coated layer and the optimization of the process,the prepared coated dialysis cover paper has excellent air permeability,which provides a theoretical basis for the process of high strength and high permeability medical coated dialysis paper.
