  • Method for preparing block polyether amide foam particles with sandbag structure
    Patent number: 11124619
    Abstract: A method for preparing block polyether amide foamed particles with sandbag structure includes: premixing modifier, filler and coupling agent, melting and blending the premixed raw materials, and preparing blended particles I with core-shell structure after underwater granulation or water tank granulation; premixing the blended particles I with block polyether amide raw material, melting and blending the premixed raw material, and preparing block polyether amide blended particles II with sandbag structure after underwater granulation or water tank cutting; putting the quantitative blended particle II into an autoclave, introducing quantitative environment-friendly physical foaming agent until the foaming agent and G2 blende particles reach a homogeneous system, evacuating autoclave pressure through a valve, and taking out block polyether amide blended particles III containing the foaming agent; and transferring the blended particles III into a thermostatic equipment at softening temperature of particles, and o
