Graphene oxide reinforced waterproof polymer emulsion preparation method

Abstract

The invention provides a graphene oxide reinforced waterproof polymer emulsion preparation method, wherein 1000 parts of the graphene oxide reinforced waterproof polymer emulsion comprise the following raw materials: 3.3-5.5 parts of an amide hydrophilic small monomer for emulsification, 6.5-15.0 parts of an alkyl hydrophobic small monomer for emulsification, 0.12-0.35 part of an emulsion initiator a, 0.24-0.56 part of a chain transfer agent, 8.3-13.5 parts of an amide hydrophilic small monomer, 35-46 parts of a flexible small monomer, 23-32 parts of an ether polymer, 2.5-6.0 parts of an initiator b, 200-280 parts of an alkyl hydrophobic small monomer, 100-160 parts of an acrylate-based hard monomer, 2.6-7.5 parts of a cross-linking agent, 1.2-2.6 parts of a neutralizer, 2.3-4.0 parts of apH regulator, 0.64-1.35 parts of a functional monomer, and the balance of deionized water. According to the invention, the polymer emulsion with advantages of good stability, strong adhesion, excellent tensile strength, excellent wear resistance and excellent water resistance is synthesized by using the amide-based strong hydrophilic monomer and the long alkyl chain hydrophobic monomer as the rawmaterials through dispersion pre-emulsification, constant-temperature polymerization, variable-speed stirring, pH adjustment and a series of processes, wherein the amide molecules can enhance the adhesion of the polymer, and the tensile strength, the water resistance and the wear resistance of the film formed by the emulsion are remarkably enhanced by graphene oxide.
