With the rapid development of modern industry, the anticorrosion work of steel materials draws more and more attention from various aspects. When steel is corroded, chemical or electrochemical multiphase reaction usually occurs on the interface of metal to convert the metal into an oxidation state, which can obviously reduce the mechanical properties of the metal material such as strength, plasticity, toughness and the like, destroy the geometric shape of metal components, increase the abrasion among parts, shorten the service life of equipment, and even cause disastrous accidents such as fire, explosion and the like. According to statistics, the steel loss caused by metal corrosion accounts for about 10-20% of the steel yield in the same year, and indirect losses such as production halt, power failure and the like caused by metal corrosion accidents cannot be calculated. Therefore, preservation is a subject to be regarded worldwide.
The acrylic paint is mainly used for metal materials such as steel, aluminum materials and the like, has the advantages of fast drying, good adhesion, good heat resistance, good weather resistance and the like, comprises solvent type acrylic paint and water-based paint acrylic paint, and compared with the solvent type acrylic paint, the water-based acrylic paint has the advantages of low toxicity, nonflammability, no organic solvent, no pollution and the like. However, acrylic paints suffer from common drawbacks during use, such as: the hardness and the flexibility of the paint are difficult to balance, the water resistance is poor, the coating is easy to generate flash corrosion, once flash corrosion points occur, the integrity of the paint film is damaged, and the rust-proof and corrosion-proof functions of the paint film are greatly reduced.
At present, there have been studies on the preparation method of modified acrylic resin coating materials, such as: chinese patent CN109777232A discloses a water-based modified acrylic acid anticorrosive paint and a preparation method thereof, wherein the water-based modified acrylic acid anticorrosive paint comprises the following components in parts by weight: 250-400 parts of core-shell structure acrylic emulsion, 100-250 parts of soap-free acrylic emulsion, 30-150 parts of pigment, 100-300 parts of filler, 0-50 parts of color paste, 3-10 parts of dispersing agent, 1-3 parts of wetting agent, 1-3 parts of defoaming agent, 5-15 parts of propylene glycol, 0.5-5 parts of multifunctional auxiliary agent, 1-3 parts of mildew inhibitor, 1-3 parts of preservative, 10-15 parts of film-forming auxiliary agent, 5-10 parts of thickening agent, 1-2 parts of neutralizing agent, 1-5 parts of flatting agent, 5-15 parts of flash inhibitor and 150-200 parts of softened water; the paint film has high mechanical strength, strong adhesive force and good corrosion resistance.
Chinese patent CN109627880A discloses a water-based acrylic acid anticorrosive paint and a preparation method thereof, belonging to the technical field of anticorrosive paints. The water-based acrylic acid anticorrosive paint comprises the following components in percentage by mass: 50-70% of water-based acrylic emulsion, 0.2-0.4% of pH regulator, 0.1-0.2% of defoaming agent, 0.3-0.6% of wetting agent, 0.5-1.5% of dispersing agent, 1-2% of graphene powder, 12-18% of inorganic toner, 2-4% of corrosion inhibitor, 2-4% of cosolvent, 2-5% of rust converting agent, 1-3% of flash rust resisting agent, 0.3-0.6% of thickening agent and the balance of deionized water.

2) cooling to room temperature, sequentially adding the polyether amine derivative modified waterborne acrylic resin, the APAO modified waterborne acrylic resin, the pH regulator, the defoaming agent and the flatting agent into a paint mixing cylinder according to the weight parts of the formula, and stirring at 500-800 rpm/min for 10-20 min;
3) adding a silane coupling agent, a film forming aid and an antifreezing agent according to the weight parts of the formula, and stirring at 500-800 rpm/min for 10-20 min;
4) sequentially adding a thickening anti-settling agent and deionized water according to the weight part of the formula, stirring at 400-600 rpm/min for 10-20 min, adjusting the viscosity to 40-45 seconds at 25 ℃, filtering and packaging to obtain the polyether amine modified acrylic resin water-based anticorrosive paint.
