NOVELTY - Preparing high-strength corrosion-resistant industrial filter cloth comprises (1) adding polyethylene terephthalate polyester slice, reinforcing particles, corrosion-resistant particles and plasticizers into extruder, and melting and extruding, and (2) weaving polyester fiber into cloth to make high-strength corrosion-resistant industrial filter cloth. The preparation method of reinforcing particles comprises (1) adding aluminum trichloride and carbon tetrachloride into reaction kettle, stirring and adding nitrobenzene, adding first intermediate, iron powder and ethanol into reaction kettle, (2) adding third intermediate, toluene and formaldehyde solution into reaction kettle, stirring and adding o-allyl phenol, and reacting fourth intermediate, formamide and formic acid to obtain fifth intermediate, and (3) dispersing graphene oxide in deionized water, adding sixth intermediate and 1-hydroxybenzotriazole, and adding ammonium persulfate under anaerobic conditions after reaction. USE - The method is useful for preparing high strength and corrosion resistant industrial filter cloth. ADVANTAGE - The filter cloth: has low strength, causes corrosion on the surface; reduces the filtering effect; has excellent abrasion resistance; improves the toughness of the reinforced particles; makes the molecular structure of itself network through polymerization; greatly enhances its strength; has excellent corrosion resistance effect; improves the toughness of the polyester fiber; and uniformly disperses in the polyester fiber.
