Abstract

The invention discloses a method for producing a resin emulsion used for water-based metallic paint and a produced resin emulsion thereof. The resin emulsion is prepared by the following raw materials by weight: 0-260 parts of styrene, 40-310 parts of methyl methacrylate, 3.0-5.0 parts of acrylamide, 16.5-23.5 parts of acrylic acid, 182-202 parts of butyl acrylate, 18-38 parts of functional unsaturated monomers, 1.1-2.1 parts of an emulsifier, 5.4-7.4 parts of a phosphorus and double bond-containing polymerizable surfactant, 8-12 parts of organosilicon monomers, and 45-55 parts of a Zn<2+> solution with a mass concentration of 12-16%. The method of the invention employs a core-shell emulsion polymerization technology to make the emulsion has an overall high vitrification temperature and alow film-forming temperature. By adopting a phosphorus and double bond-containing polymerizable surfactant, the water proofness and corrosion resistance of the emulsion are enhanced. By using a dual normal-temperature self-crosslinking technology, a compact netted polymer structure can be formed, so that the emulsion can has good adhesive force, hear resistance, wear resistance, as well as the advantages of energy saving, environmental protection, nontoxicity and harmlessness.

Description

technical field [0001] The invention relates to the technical field of metal paint, in particular to a resin emulsion for water-based metal paint and a production method thereof. Background technique [0002] At present, in the anti-corrosion coating of mechanical equipment and various metal products, most of the downstream petrochemical products are used as solvents. During the production and use process, it will cause great harm to human health, and the fire and explosion caused will be harmful to people's lives and properties. cause huge losses. Organic solvents are discharged into the atmosphere, causing serious air pollution and are difficult to degrade, and are also a huge waste of energy. Now the country and the whole world are vigorously advocating ecological environmental protection, energy conservation and emission reduction, and have been included in the national development implementation plan. Contents of the invention [0003] The technical problem to be so...
