A kind of preparation method of graphene oxide reinforced waterproof polymer emulsion

Abstract

The invention provides a preparation method of graphene oxide reinforced waterproof polymer emulsion. Required raw materials: 3.3-5.5 parts of amide-based hydrophilic small monomers for emulsification, 6.5-15.0 parts of alkyl-based hydrophobic small monomers for emulsification, 0.12-0.35 parts of emulsion initiator a, 0.24-0.56 parts of chain transfer agent, amides 8.3-13.5 parts of hydrophilic small monomers, 35-46 parts of flexible small monomers, 23-32 parts of ether polymers, 2.5-6.0 parts of initiator b, 200-280 parts of alkyl hydrophobic small monomers, acrylic acid 100-160 parts of hard ester monomer, 2.6-7.5 parts of cross-linking agent, 1.2-2.6 parts of neutralizing agent, 2.3-4.0 parts of pH regulator, 0.64-1.35 parts of functional monomer, and 1000 parts of deionized water. The present invention uses amide-based strong hydrophilic monomers and long alkyl chain hydrophobic monomers as raw materials, and synthesizes a product with good stability, strong adhesion, and Polymer emulsion with excellent tensile, wear-resistant, and waterproof properties, in which amide-based molecules strengthen the adhesion of the polymer, and graphene oxide significantly enhances the tensile strength, water resistance, and abrasion resistance of the emulsion film.
