titleOfInvention | A kind of nano-montmorillonite and polymer composite viscosity reducer and preparation method thereof |
abstract | The invention discloses a nanometer montmorillonite and polymer composite viscosity reducer and a preparation method thereof. The preparation method uses organic montmorillonite, high-carbon alkyl methacrylate and acrylamide as raw materials, and methacrylic acid high Carbon alcohol ester and acrylamide are polymerized in the sheets of organic montmorillonite to obtain nano-montmorillonite and polymer composite viscosity reducer; wherein, the organic montmorillonite uses organic quaternary ammonium salt as intercalation agent For the modified montmorillonite nanoparticles, the high-carbon alkyl group in the high-carbon alkyl methacrylate refers to a straight-chain alkyl group with 12-22 carbon atoms. The viscosity reducing agent prepared by the method has high viscosity reducing rate, simple preparation method, low raw material cost, and can reduce viscosity reducing cost. |
