Description
Technical Field
The invention relates to the technical field of paint preparation, in particular to a special anticorrosive paint for a steel structure and a preparation method thereof.
Background
The direct economic loss due to metal corrosion is reported to account for about 4% of the total value of national production in China each year. The corrosion protection of metals is therefore of great interest, and the application of anticorrosive coatings is currently the most convenient and economical means. The solvent type antirust coating has excellent antirust and anticorrosive effects and universality, and is widely applied in the industrial fields of steel structures, petrifaction, machinery and the like. As is known, the traditional solvent-based paint contains a large amount of organic solvents, has many problems in the aspects of safety and environmental protection, has great hidden dangers for people and the environment, and the national emission limit for VOC is gradually tightened, so that the trend of upgrading from the water-based paint to the environmental protection type is imperative in the face of increasingly severe environmental protection situation.
At present, the water-based anticorrosive paint special for the steel structure mainly takes water-based acrylic emulsion paint as a main material, although the paint has high drying speed, the paint has the defects of poor fullness, easy whitening of a paint film when meeting water, poor film forming at low temperature, easy rust return under a high-humidity environment, high requirement on substrate treatment and the like, and the development of the water-based steel structure anticorrosive paint is severely limited due to high cost.

The invention also provides a preparation method of the special water-based acrylic acid modified alkyd anticorrosive paint for the steel structure, which comprises the following specific steps: adding 40-60 parts of water-based acrylic acid modified alkyd resin, (0.1-0.3) part of dispersing agent and (5-15) parts of deionized water into a dispersing kettle, uniformly dispersing at a high speed, adding 0-1.5 parts of anti-settling additive, (10-20) parts of pigment, (5-15) parts of filler and (5-15) parts of antirust base material, fully stirring uniformly, sanding until the fineness reaches 40 mu m, adding 0.1-0.5 part of leveling additive, (0.1-0.3) part of defoaming agent, (0.5-1) part of anti-flash rust agent and (0.3-0.6) part of thickening agent, fully stirring uniformly, and adjusting the viscosity to 120-140 s by using the rest (5-10) parts of deionized water.
The anticorrosive coating is prepared by self-preparing waterborne acrylic modified alkyd resin, grafting an acrylic monomer and an organic silicon monomer onto the alkyd resin by a free radical polymerization grafting process, wherein the solid content of the obtained resin is high and reaches more than 46 percent and is far higher than about 40 percent of the solid content of the current commercially available waterborne acrylic modified alkyd resin product, and the anticorrosive coating is high in drying speed, high in paint film fullness, good in weather resistance and excellent in adhesive force to a substrate; organic silicon monomers are introduced into the resin molecules, so that the hydrophobicity of the surface of the paint film is improved, and the water resistance and the corrosion resistance of the paint film are improved. The invention adopts the low-boiling point, low-toxicity and low-odor 2-tert-butoxyethanol to replace the traditional toxic cosolvent such as ethylene glycol butyl ether and the like, thereby improving the drying speed of the paint film and reducing the harm to the environment and constructors. During resin synthesis, a large amount of acrylic monomers are grafted, the drying speed is high under low-temperature and high-humidity conditions, and the problem that the drying speed is influenced because a large amount of film-forming additives are needed at low temperature of emulsions is solved. The rust-proof base materials such as the zinc-aluminum phosphate polymer, the modified aluminum tripolyphosphate, the iron zinc phosphate and the like have strong chemical activity and interact with the film-forming base materials, so that a complex paint film consisting of chemical bonds and physical bonding is generated on the surface of metal, the rust-proof coating has strong inhibition effect on corrosion of metal such as steel and the like, and flash rust can be effectively prevented from being generated by coating a small amount of iron rust metal base materials. The paint has high solid content, low VOC content, thick one-time spraying and low requirement on construction environment, can completely replace the oil steel structure anticorrosive paint in the field of light corrosion resistance, and has remarkable economic benefit.
