Embodiment 1
[0027] Preparation of porous coated resin foam particles:
[0028] Through a twin-screw extrusion granulation device, polypropylene (PP) thermoplastic resin is made into thermoplastic resin particles with a diameter of 2 μm by melt extrusion; it is put into an autoclave, and high-pressure gas (CO 2 , N 2 ) and organic solvent (chloroform, ethanol) to form a high-pressure mixed fluid, the pressure of the high-pressure fluid is 2MPa, and the weight ratio of each component of the high-pressure mixed fluid is CO 2 :N 2 : chloroform: ethanol = 1:1:1:1; make the high-pressure mixed fluid reach saturation in the thermoplastic resin particles, and finally heat and foam the saturated thermoplastic resin particles in 150°C continuous hot air medium to obtain the degree of expansion High, foamed thermoplastic resin particles with a closed-cell structure and a particle size of 12 μm.
