【摘要】：目的研究一种既具有湿度调节功能,又具有缓冲吸能特性的新型缓冲包装材料的制备及性能,解决部分精密仪器运输存贮中受潮或过于干燥影响精度的问题。方法利用微波发泡方法制备得到具有调湿功能的发泡缓冲包装材料,研究影响该材料发泡性能、调湿性能、缓冲性能的因素,并对最佳组分配比下制得发泡材料的性能进行测试。结果微波发泡功率为122.5 W,丙烯酸-丙烯酸钠与丙烯酰胺质量比为4∶1,KGM基调湿材料初始含水体积为6.5 m L时,所制得调湿发泡材料的性能最佳,能在180min内将密闭容器内环境的相对湿度调节至(50±5)%,同时该材料还具有优异的缓冲吸能特性,单位体积总吸收能量为1.73 J/cm~3,最小缓冲系数为3.32。结论影响该新型发泡材料的发泡性能、调湿性能和缓冲性能的因素有微波发泡功率,丙烯酸-丙烯酸钠与丙烯酰胺的质量比,魔芋葡甘聚糖(KGM)基调湿材料的初始含水体积。
[Abstract]:Objective to study the preparation and properties of a new cushioning packaging material with humidity regulation function and cushioning energy absorption characteristics, and to solve the problem of moisture or excessive dryness affecting the accuracy of some precision instruments in transportation and storage. Methods the foaming cushioning packaging material with humidification function was prepared by microwave foaming method, and the factors affecting the foaming performance, humidification property and cushioning performance of the material were studied. The properties of the foamed material prepared by the optimal group distribution ratio were tested. Results when the microwave foaming power was 122.5 W, the mass ratio of acrylic acid to sodium acrylic acid to acrylamide was 4 鈮，
