Description
Technical Field
The invention relates to the technical field of chemical coatings, in particular to a high-temperature-resistant anticorrosive coating and a preparation method thereof.
Background
According to the data at home and abroad, the existing high-temperature resistant systems are divided into two categories of inorganic silicon high-temperature resistant coatings and organic high-temperature resistant coatings. The inorganic high-temperature resistant paint mainly comprises ceramic paint, silicate paint, phosphate paint, zinc-rich primer and the like, and although the inorganic series is environment-friendly, the requirement on the pretreatment of the base material is high, so that the application of the inorganic high-temperature resistant paint is indirectly limited. The organic high-temperature resistant coating mainly comprises fluorocarbon resin coating, heterocyclic polymer coating, organic silicon high-temperature resistant coating and the like. The organic silicon resin contains Si-O bond with larger energy and good stability under high temperature. However, the common organic silicon high-temperature resistant coating can be dried only by baking for 1-3 hours at about 200 ℃, the paint film is softer, and the energy consumption is higher in the construction process.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a high-temperature-resistant anticorrosive coating. The component A is prepared by mixing high-temperature resistant resin serving as main resin, high-temperature resistant pigment serving as coloring pigment, antirust material, framework material, structure reinforcing material and organic solvent. The component B adopts a mixture of a cross-linking agent containing active groups and an organic solvent.
The technical scheme for realizing the purpose of the invention is as follows: a high-temperature resistant anticorrosive paint comprises a component A and a component B;
the component A is prepared from the following components in parts by mass:
the component B is prepared from the following components in parts by mass:
30-90 parts of cross-linking agent
10-70 parts of organic solvent
Further, the high-temperature resistant resin is one or more of organosilicon containing hydroxyl functional groups and modified organosilicon resin.
Further, the anti-settling agent is one or more of bentonite, polyamide wax and polyethylene wax.
Furthermore, the pigment is one or more of high temperature resistant pigments such as high temperature resistant titanium white, ceramic black, cobalt black, cadmium red, titanium nickel yellow and the like.
Further, the antirust material is one or more of high-temperature-resistant antirust fillers such as zinc phosphate, aluminum tripolyphosphate and the like.
Further, the framework material is a mixture of coarse glass powder (100-300 meshes) and fine glass powder (400-800 meshes), and the ratio is (1-5): 1.
Furthermore, the structural reinforcing material is one or more of silica powder, talcum powder, kaolin and mica powder.
Furthermore, the organic solvents in the component A and the component B are one or more common organic solvents for the coating, such as dimethylbenzene, butyl acetate, dimethyl isobutyl ketone and the like.
Further, the crosslinking agent is one or more of an isocyanate crosslinking agent and an aminosilane coupling agent.
A preparation method of a high-temperature-resistant anticorrosive paint comprises the following steps:
(1) putting the high-temperature-resistant resin, the anti-settling agent, the pigment, the antirust material, the structure reinforcing material and the organic solvent in the component A formula into a container, stirring at the rotating speed of a dispersion machine of 800-1000 r/m for 30 min;
(2) grinding the slurry by using a horizontal sand mill until the fineness is less than 40 mu m;
(3) putting the framework material into a container filled with the ground slurry, stirring for 1-2 hours at the rotating speed of a dispersion machine of 800-1000 r/m, and filtering and discharging;
(4) mixing the cross-linking agent and the organic solvent in the component B, stirring for 30min at the rotation speed of 500-800r/m of a dispersion machine, and filtering and packaging.
After the technical scheme is adopted, the invention has the following positive effects:
(1) the invention adopts a double-component scheme, can completely carry out film forming at normal temperature, and saves energy consumption in the high-temperature film forming process; the surface treatment requirement of common anticorrosive paint can be referred to in the treatment of the base material in the construction process, the construction difficulty is reduced, and the stability of a paint film at the high temperature of 600 ℃ is not influenced after the film is formed.
(2) According to the invention, the organic silicon resin and the cross-linking agent are used as basic film forming materials, and the compound glass powder is used as auxiliary film forming materials at different temperature stages, so that the purpose of high temperature resistance is achieved, after the film is formed, the paint film can be kept at the temperature of 600 ℃ for more than 4 hours, and the paint film is not foamed or dropped after being taken out; wherein the proportion of the coarse glass powder (100-300 meshes) and the fine glass powder (400-800 meshes) in the compound glass powder determines whether the paint film is foamed or peeled under the high-temperature condition. The melting point difference between the coarse glass powder and the fine glass powder is mainly utilized to convert a paint film at different temperature stages. And (3) keeping the temperature at 600 ℃ for 4 hours, taking out the paint film, and cooling the paint film at room temperature, wherein the paint film does not bubble, bubble or fall off.
