  • Publication number: 20250129253
    Abstract: The present invention relates to a kind of pigment preparation, in particular to a modified layered silicate novel barrier and shielding pigment and its preparation method. It is a layer silicate with exchangeable anticorrosive ions as a template, using metal oxides or metal salts, inorganic acids to synthesize nano-spherical zinc phosphate, phosphate, molybdate, borate or tungstate, with rare earth cerium, strontium, lanthanum or praseodymium doped modification of the pigment. The invention uses silicate as a template to effectively control the agglomeration of nanoparticles during the liquid phase deposition process, avoiding the multiple cleaning and sewage treatment processes required by using surfactants and solvents. What is more valuable is lamellar silicic acid. The salt itself has certain anti-corrosion properties and is economical.
