Abstract

The invention relates to an environmental-friendly polypropylene foaming bead. Preparation of the foaming bead comprises steps of: a) subjecting a polypropylene resin and a porous material with an adsorption function to mixing, extrusion, wire drawing and granulation through an extruder to obtain polypropylene particles; and b) adding the polypropylene particles into a reactor, heating and pressuring, and releasing into the air in an instant to obtain a certain multiplying power of the environmental-friendly polypropylene foaming beads having adsorption, air purification and disinfection functions. The porous material with the adsorption function comprises active silicon, active carbon, active alumina, bamboo charcoal, graphitized carbon black, active carbon fiber, and the like. The porous material with the adsorption function accounts for 0.1%-20% by weight of the total adding amount of the polypropylene. The porous material with the adsorption function has a particle size of 700-1200 meshes, and a pore diameter of 2-500 nm. The polypropylene foaming bead has a great application potential in environment purification of automobile inner decoration, home decoration, and other industries.
