Description
Technical Field
The invention relates to the technical field of water treatment, in particular to a coating circulating water treatment agent and a preparation method thereof.
Background
Painting is an important step in modern product manufacturing processes. The quality of antirust and anticorrosive coatings is one of the important aspects of the overall quality of products. The appearance quality of the product not only reflects the protection and decoration performance of the product, but also is an important factor forming the value of the product. Along with the wide application of coating, the collection of coating paint mist is more and more emphasized, and the collection of the coating paint mist is basically collected by circulating water at present. The general coating circulating water contains a large amount of toxic and harmful substances such as paint molecules, thinner and the like, and contains a large amount of nonionic wetting dispersant, emulsifier and anionic surfactant. Generally, the coating wastewater is treated by using a sewage treatment agent such as a paint mist coagulant or a flocculating agent, and the treated wastewater can be recycled, so that the enterprise cost is reduced.
In order to purify the coating circulating water, the coating wastewater is usually adsorbed by sepiolite, and the treated circulating water is recycled, so that the enterprise cost is reduced. The particular structure of sepiolite determines its ability to have channels and holes throughout the structure and a large surface area, it has tubular through channels with a cross-sectional area of 0.36nm by 1.06nm and a theoretical surface area of up to 900 square meters per gram. Large amounts of water or polar substances, including low-polarity substances, can be adsorbed in the channels and the holes, so that the sepiolite has strong adsorption capacity. Technical background:
untreated sepiolite absorbs a lot of water when it encounters water and becomes soft and hard once it dries. Although the coating has super large specific surface area and developed adsorption pore channels, a large number of water molecules occupy the adsorption pore channels after meeting water, and the adsorption capacity of the coating on organic matters in coating circulating water is greatly reduced. Therefore, the application of the paint in the field of coating circulating water treatment is restricted.

Detailed Description
The technical solution of the present invention is described in detail below with reference to examples.
The embodiment of the invention provides a preparation method of a coating circulating water treatment agent, which comprises the following steps:
dispersing sepiolite powder in an organic solvent, adding a wetting agent to prepare slurry with the solid content of 80%, adding organic acid and methylsilicate into the slurry, heating and stirring to distill and remove volatile components, and grinding to prepare the hydrophobic modified sepiolite powder, wherein the organic solvent comprises a 95% ethanol solution; washing hydrophobic modified sepiolite powder with deionized water for 2-3 times, and drying at 107 deg.C to obtain refined sepiolite powder.
The steps finish the hydrophobic modification of the sepiolite pore channels (inhibiting the adsorption of the pore channels to water molecules), wherein 95 percent of ethanol solution contains water, and organic acid can ionize H after meeting water+The methyl silicate is usually selected to be sodium methyl silicate or potassium methyl silicate, and the following chemical reactions can exist in the system:
CH3-SiOOK+H+→CH3-SiOOH+K+or
CH3-SiOONa+H+→CH3-SiOOH+Na+，
The reaction product methylsilicic acid is a hydrophobic substance. The sepiolite powder is fully wetted with the organic solvent under the action of the wetting agent, the micromolecule methyl silicate can fully enter the sepiolite pore passage along with the organic solvent, and after the organic acid is added, the methyl silicate and the H are mixed+Reacting to form an acid-alkali-resistant methyl silicic acid hydrophobic coating which can inhibit the adsorption of the pore channels to water molecules; the alcoholic solution can provide water required by organic acid ionization, and the water required by the reaction is controlled by controlling the addition of the alcoholic solution, so that the modification of the hydrophobicity of the channel is not facilitated by too much water, and the water content is too low to enable the organic acid to be sufficiently ionized to obtain H required by the reaction+In the above process, the reaction can be accelerated by heating and stirring, and in order to further improve the dispersing ability, the reaction can be accelerated by stirringWith 95% ethanol as solvent, other organic solvents, e.g. 200#Solvent oil. The sepiolite powder prepared by the scheme can inhibit the pore channels of the sepiolite powder from adsorbing water molecules, so that a large number of water molecules are prevented from occupying the adsorption pore channels after meeting water, the adsorption capacity of the sepiolite powder on organic matters in coating circulating water is greatly improved, and selective adsorption is realized.
In some examples, the coating cycle water treatment agent is prepared by mixing the refined sepiolite powder prepared in the above examples with an organic quaternary ammonium salt, adding a wetting agent, heating and stirring for 2 hours, washing the reacted refined sepiolite powder with deionized water for 3 times, and drying and grinding the washed sepiolite powder. After the pore channels of the sepiolite powder are subjected to hydrophobicity modification, in the process of quaternization, the hydrophobic end of the quaternary ammonium salt preferentially enters the pore channels, and a large number of cationic ends are exposed at the port of the pore channels, so that on one hand, a large number of anionic active ingredients can be captured, on the other hand, the pore channels are subjected to hydrophobicity modification, but the sepiolite unit cells still have the function of dispersing in water.
Through the steps, on one hand, a pore channel of the sepiolite powder can adsorb a specific amount of cationic organic matters, so that the channel with a large specific surface area can carry a certain cationic charge, and the high-density cationic charge carried by the channel can adsorb and separate the organic matters with anionic charges in the coating circulating water through electrostatic adsorption, so that the organic matters are inactivated; on the other hand, the pore channels can adsorb a large amount of active ingredients such as nonionic wetting dispersants and emulsifiers in the coating circulating water, so that the coating circulating water resin, the pigment and the filler are separated, and after the active ingredients such as the nonionic wetting dispersants and the emulsifiers are stripped from the surfaces of the resin, the filler and the pigment through the adsorbing materials, the components of the paint are destabilized to form flocculent (emulsion breaking). Finally, paint water separation in the coating circulating water can be thoroughly realized.
In some embodiments, dispersing the sepiolite powder in the organic solvent further comprises: adding organic or inorganic acid into sepiolite raw ore powder, stirring, standing, filtering, drying and grinding a filter cake, and controlling the water content of the filter cake to be 0.1-4% to obtain sepiolite powder. The step can dredge the pore channel of the sepiolite through acidification, and dissolve out acid-soluble ions or organic matters from the pore channel.
