[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，
