The invention belongs to functional plastics fields, provide a kind of preparation method of diatom soil matrix antistatic plastic masterbatch.This method is by the way that diatomite is crushed, after removing mineral dregs, clay mineral and organic substance, under hydrochloric acid solution effect, silver nitrate is made to be fully dispersed in the surface in diatomite and micropore, the diatomite of load silver chlorate is formed, then with matrix resin in screw mixing, while reducing agent is passed through in screw rod, silver chlorate in-situ reducing is made to obtain the excellent antistatic plastic masterbatch of dispersion performance for elemental silver.The defects of directly being difficult to disperse by metal powder addition matrix resin the method overcome tradition, is suitble to large-scale production. |
