Description
Technical Field
The invention belongs to the technical field of water-based paint, and particularly relates to efficient anticorrosive water-based acrylic paint and a preparation method thereof.
Background
The coating is used as a common important chemical product, is generally applied to almost all trades such as buildings, aviation, ships, automobiles and the like, and plays a functional role in appearance decoration, weather resistance, corrosion resistance and the like. With the development of engineering technology, special working environments are more and more common, and coatings used in severe environments have become important research contents. The development of resin as a base part of organic coating composition as a protective material having high temperature resistance, multiple purposes and excellent performance has been the focus of research in recent years.
With the increasing awareness of environmental protection and the health of environmental regulations, the use of Volatile Organic Compounds (VOC) and Hazardous Air Pollutants (HAP) in traditional solvent-based coatings is increasingly limited, and high solids coatings are receiving more and more attention. The water-based acrylic resin coating is widely applied to the water-based coating, has the characteristics of light color, high transparency, good corrosion resistance, small absorption in an infrared region, numerous monomers, low price, good glossiness, high fullness and the like, is low in VOC content, does not contain organic volatile matters in the using process, does not pollute the environment, has defects in water resistance, mechanical property and barrier property of nitrogen, influences the anticorrosion function of the nitrogen, and is limited in application in partial fields, so that the water-based acrylic resin coating is required to be improved to improve the overall performance of the nitrogen, and the application range of the water-based acrylic coating is expanded.
Disclosure of Invention
The invention aims to make up the defects of the prior art and provides a high-efficiency anticorrosive water-based acrylic paint and a preparation method thereof.
In order to achieve the above object, the present invention provides the following technical solutions:
an efficient anticorrosive water-based acrylic coating is prepared from the following raw materials in parts by weight: 50-60 parts of methyl methacrylate, 12-15 parts of styrene, 3-5 parts of styrene microsphere solution, 55-70 parts of n-butyl acrylate, 5-7 parts of gamma-methacryloxypropyltrimethoxysilane, 4-6 parts of sodium dodecyl sulfate, 10-12 parts of alkylphenol polyoxyethylene, 0.05-0.1 part of ammonium persulfate, 0.04-0.08 part of sodium bicarbonate, 32-34 parts of coarse whiting powder, 8-10 parts of dodecanol ester, 0.3-0.6 part of polyamine curing agent, a proper amount of ammonia water and a proper amount of deionized water.
Preferably, the efficient anticorrosive water-based acrylic coating is prepared from the following raw materials in parts by weight: 55 parts of methyl methacrylate, 13.5 parts of styrene, 4 parts of styrene microsphere solution, 63 parts of n-butyl acrylate, 6 parts of gamma-methacryloxypropyltrimethoxysilane, 5 parts of sodium dodecyl sulfate, 11 parts of alkylphenol polyoxyethylene, 0.07 part of ammonium persulfate, 0.06 part of sodium bicarbonate, 33 parts of coarse whiting powder, 9 parts of dodecanol ester, 0.4 part of polyamine curing agent, a proper amount of ammonia water and a proper amount of deionized water.
Further, the preparation method of the styrene microsphere solution comprises the following steps: taking potassium persulfate and monomer styrene according to a mass ratio of 1: 80, adding the mixture into deionized water with the mass of 30-50 times, stirring and dissolving, then adding 0.05% of sodium bicarbonate, stirring uniformly under the protection of nitrogen, heating until the reaction is finished, and dialyzing the obtained product in distilled water for 3-4 days to obtain the styrene microsphere solution.
Furthermore, the temperature of the heating reaction is controlled to be 75-85 ℃, the stirring is continuously carried out at 200-300 r/min in the reaction process, and the reaction is completed within 4-6 hours.
The preparation method of the efficient anticorrosive water-based acrylic coating specifically comprises the following steps:
(1) mixing methyl methacrylate, styrene, n-butyl acrylate and gamma-methacryloxypropyltrimethoxysilane as reaction monomers, mixing sodium dodecyl sulfate and alkylphenol ethoxylates as an emulsifier, mixing the two, adding deionized water, stirring and dissolving uniformly to obtain a pre-emulsion for later use;
(2) dissolving ammonium persulfate in deionized water of which the mass is 240-260 times that of the ammonium persulfate, and uniformly stirring to form an ammonium persulfate solution for later use;
(3) dissolving sodium bicarbonate in deionized water with the mass of 350 times that of 300-fold, adding 1/3 pre-emulsion, heating to 65-75 ℃, then adding 1/2 ammonium persulfate solution, and uniformly stirring to obtain seed emulsion for later use;
(4) adding a styrene microsphere solution, a dodecyl alcohol ester and a polyamine curing agent into the seed emulsion, stirring uniformly, then adding the rest pre-emulsion and an ammonium persulfate solution in batches, adding ammonia water to adjust the pH value to 7.5-8.0 when the emulsion presents milky bluish light, finally adding heavy calcium powder, stirring for 25-35 minutes, adding water and adjusting to proper viscosity, thus obtaining the coating.
Further, the adding amount of the deionized water in the step (1) is controlled to be 1: (0.65-0.75).
Further, the residual pre-emulsion and ammonium persulfate solution in the step (4) are added in two times, half of the residual pre-emulsion and ammonium persulfate solution are added in each time, the heating interval is 30 minutes in each time, and the temperature is kept at 65-75 ℃ in the whole process.
Further, after the heavy calcium powder is added in the step (4), the stirring speed is controlled to be 600 revolutions per minute and 1000 revolutions per minute during stirring.
The invention has the advantages that:
according to the invention, a silane coupling agent is introduced to carry out modification treatment on the basis of conventional water-based acrylic acid, wherein gamma-methacryloxypropyltrimethoxysilane provides a hydrophobic group through cohesive energy, hydrolytic crosslinking with acrylic acid in film formation enhances the compactness of a coating film, and forms a hydrophobic layer on the surface, so that moisture cannot permeate into the coating, the water resistance of the coating is enhanced, meanwhile, the terminal alkenyl group contained in the silane coupling agent further forms various crosslinking points with the acrylic acid, the weather resistance and the mechanical property of acrylic resin can be enhanced, and the corrosion resistance of the material is improved from the side.
The invention adds the styrene microsphere solution into the acrylic resin, wherein a large amount of styrene organic microspheres are contained as the filler, the surface of the styrene organic microspheres has a large amount of negative charges, and the styrene organic microspheres can form additional interaction points with polyamine curing agent with positive charges and the acrylic modified resin under the action of electrostatic adsorption, so that the filler and the acrylic base material are combined more tightly, the compactness and the barrier property of the coating are improved, and the diffusion path of a corrosive medium in the coating is effectively reduced. Meanwhile, a coating formed after the coating is used can generate partial microscopic pores due to the volatilization of a solvent in the curing process, and the styrene organic microsphere filler can be automatically filled into the pores, so that the coating absorbs stress when stressed and weakens the microscopic cracks generated when the coating receives stronger acting force, and the mechanical property of the coating is improved.
The efficient anti-corrosion water-based acrylic coating disclosed by the invention is mild in reaction conditions and simple in preparation conditions, can effectively improve the water resistance, mechanical property, barrier property and the like of the water-based acrylic coating, further greatly enhances the anti-corrosion property of the water-based acrylic coating, effectively expands the use field of water-based acrylic materials, and has an ideal market prospect.
