Description
Technical Field
The invention relates to the technical field of building coatings, and discloses a water-based anticorrosive industrial paint and a preparation method thereof.
Background
The corrosion is a destructive erosion caused by chemical or electrochemical reaction between metal and the surrounding environment, and compared with the 'surprise natural disasters' such as earthquake, typhoon and the like, the damage is easily ignored because the corrosion occurs under the condition of being silent, and the damage is really more serious than the loss caused by the natural disasters, so that the corrosion not only consumes resources, but also causes environmental pollution, and even harms the health and safety of human beings. According to macroscopic statistics and investigation, the economic loss caused by corrosion accounts for about 3-4% of GDP every year, and the economic loss caused by corrosion is several times of the sum of losses caused by various natural disasters. The anticorrosive coating is widely applied to a plurality of fields such as steel structure construction, ship transportation and the like due to the excellent anticorrosive and antirust functions, and the serious waste of resources and energy caused by metal corrosion is effectively avoided. In the common water-based paint, the paint only generally plays a role of decoration, and has no other specific functions, wherein water in the paint even accelerates the corrosion of steel materials, and the paint cannot play a role of corrosion prevention and rust prevention. However, with the process of water-based paint industry, more and more people pay more attention to the water-based anticorrosive paint. Therefore, the developed water-based anticorrosive and antirust coating with excellent performance has great market prospect and social value.
The existing authorized water-based anticorrosive industrial paint is relatively few, such as high-mechanical-performance hydroxyl-containing polyurethane copolymerized acrylic acid water-based industrial paint disclosed in application publication No. CN 104789104A, the coating is called as a two-component coating, the main agent is composed of components of hydroxyl-containing polyurethane/acrylic acid emulsion, defoaming agent, pigment, wetting agent and water, and the curing agent is hydrophilic modified HDI tripolymer. Although the invention has the higher mechanical properties of the hardness of 1H, the impact resistance of 50kg, the adhesive force of 1 grade and the like, the invention is a two-component coating, needs to be baked for 15-30min at 150 ℃ and is inconvenient to use.

Preferably, the emulsifier is prepared by compounding an anionic emulsifier and a nonionic emulsifier according to the weight ratio of 1; the initiator is at least one of potassium persulfate and sodium persulfate.
The preparation method of the water-based anticorrosive industrial paint comprises the following steps of sequentially carrying out:
1) Adding deionized water, an emulsifier and a reaction monomer into a reaction kettle according to the weight parts, stirring at a high speed for 10-30 min, adding an initiator and the deionized water to prepare a solution with the concentration of 6wt%, slowly dripping the solution into the reaction kettle, continuously reacting at a high temperature for 2-4 h, stopping the reaction, and cooling the emulsion to room temperature to obtain the fluorine-silicon modified styrene-acrylic emulsion;
2) Sequentially adding deionized water, a dispersing agent, a wetting agent, a thickening agent, a 1/2 defoaming agent and a stabilizing agent into a dispersion kettle according to the weight parts, uniformly stirring, then adding titanium dioxide, iron oxide red, sericite, silicon micropowder and heavy calcium, and preparing into pre-slurrying with the fineness of less than or equal to 60 mu m; and then adding the fluorosilicone modified styrene-acrylic emulsion obtained in the step 1) and the inorganic potassium silicate to uniformly disperse to obtain the water-based anticorrosive industrial paint.

Comparative example:
1) Adding 80 parts by weight of deionized water, 0.2 part by weight of emulsifier, 5 parts by weight of styrene, 10 parts by weight of methyl methacrylate, 20 parts by weight of butyl acrylate and 5 parts by weight of methacryloxy silane into a reaction kettle, stirring at a high speed for 10-30 min, adding 0.1 part by weight of initiator into deionized water to prepare 6wt% solution, slowly dropwise adding into the reaction kettle, continuing to react at a high temperature for 2-4 h, stopping the reaction, and cooling the emulsion to room temperature to obtain the self-crosslinking styrene-acrylic emulsion;

The relevant technical indexes of the examples 1 to 4 and the comparative example 1 are detected by referring to the industrial standard HG/T5176-2017 waterborne anticorrosive paint for steel structures. Tests prove that the product meets the standard requirements of related self-cleaning coatings, has excellent paint film performance, and has the main performance indexes shown in table 1.
As can be seen from Table 1, comparative example 1, in which no fluorosilicone modified styrene-acrylic emulsion was added, had excellent adhesion and weathering resistance, but the water and salt spray resistance of the paint film was poor due to the strong hydrophilicity of potassium silicate. In the embodiments 1-4 added with the fluorine-silicon modified styrene-acrylic emulsion, the paint film has lower surface energy due to the introduction of the C-F bond and the Si-O bond, so that the corrosion medium can be effectively prevented from permeating into the base material, and the water resistance and the salt spray resistance of the paint film are greatly improved. The product is a water-based paint, the addition of organic solvents such as film forming aids and antifreeze is reduced by a special preparation method, and the content of organic volatile matters is far lower than that specified in HG/T5176-2017 Water-based anticorrosive paint for steel structures.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make various modifications and changes without departing from the inventive concept, which falls within the scope of the present invention.
